The Instant Pot, a kitchen marvel, has revolutionized cooking, offering speed and convenience, especially when it comes to tough cuts of meat like roast. But a common question plagues both novice and experienced Instant Pot users: Does the roast need to be fully submerged in liquid for optimal results? The answer, as with many culinary questions, isn’t a straightforward yes or no. It’s nuanced and depends on several factors. This article dives deep into the science, techniques, and considerations surrounding liquid levels in Instant Pot roasts, equipping you with the knowledge to achieve perfectly cooked, flavorful roasts every time.
Understanding the Instant Pot’s Cooking Process
To understand whether your roast needs to swim in liquid, it’s crucial to grasp how the Instant Pot cooks. It operates under pressure, significantly raising the boiling point of water. This superheated steam cooks food much faster than traditional methods.
The liquid in the Instant Pot plays several key roles. It generates the steam necessary for pressure cooking, helps distribute heat evenly, and prevents the food from burning on the bottom of the pot. The liquid also contributes to the overall flavor and moisture content of the final dish.
The Role of Steam in Cooking
Steam is the primary cooking agent in an Instant Pot. As the liquid heats up, it transforms into steam, which then builds pressure inside the sealed pot. This high-pressure steam penetrates the meat, tenderizing tough fibers and cooking it quickly and efficiently.
Heat Distribution and Preventing Burning
The liquid also ensures even heat distribution. Without enough liquid, the bottom of the roast could scorch or burn before the rest is cooked through. The steam, generated from the liquid, circulates around the roast, ensuring uniform cooking.
Flavor Infusion and Moisture Retention
Beyond cooking, the liquid adds flavor to the roast. Whether it’s broth, wine, or a simple combination of water and seasonings, the liquid infuses the meat with delicious flavors. It also helps retain moisture, preventing the roast from drying out during the cooking process.
To Submerge or Not to Submerge: Factors to Consider
Whether or not your roast needs to be fully covered in liquid depends on several factors, including the type of roast, the desired outcome, and the cooking time. There’s no universal rule, but understanding these elements will guide you toward the best approach.
Type of Roast and Cut of Meat
Different cuts of meat behave differently in the Instant Pot. Tougher cuts, like chuck roast, benefit from longer cooking times and more liquid, as this helps break down the connective tissues and tenderize the meat.
Leaner cuts, like sirloin tip roast, can become dry if overcooked or if there’s too much liquid diluting the flavor. These cuts often require less liquid and shorter cooking times.
Desired Outcome: Braised vs. Roasted
The level of submersion also depends on whether you want a braised or roasted effect. A braised roast, where the meat is cooked in a generous amount of liquid, results in a fall-apart tender texture and a rich sauce.
A roasted effect, where the meat is browned on the outside and cooked to a specific internal temperature, requires less liquid and often involves a trivet to elevate the roast above the liquid line.
Cooking Time and Pressure Level
Longer cooking times necessitate more liquid to prevent scorching and maintain sufficient steam pressure. Conversely, shorter cooking times may require less liquid, especially for smaller roasts. The pressure level (high or low) also influences the amount of liquid needed. High pressure generally requires more liquid than low pressure.
Practical Guidelines for Liquid Levels
While the exact amount of liquid can vary, these general guidelines will help you determine the appropriate level for your Instant Pot roast. Remember, it’s always better to err on the side of slightly more liquid than not enough.
Minimum Liquid Requirement
The Instant Pot requires a minimum amount of liquid to function correctly and build pressure. This minimum is typically around 1 cup (8 ounces) for most 6-quart Instant Pots and 1.5 cups for 8-quart models. Refer to your Instant Pot’s manual for the specific recommended minimum.
Submersion vs. Partial Immersion
For tougher cuts of meat that you want to braise, aim for partial submersion. The roast doesn’t need to be completely covered, but at least half of it should be submerged in liquid. This allows the meat to cook evenly and develop a rich, flavorful sauce.
For leaner cuts or when aiming for a roasted effect, use a trivet to elevate the roast above the liquid line. Add enough liquid to reach just below the trivet, ensuring that the bottom of the roast doesn’t sit in the liquid.
Adjusting Liquid Based on Ingredients
Consider the moisture content of other ingredients you’re adding to the Instant Pot. Vegetables like onions, celery, and carrots release moisture as they cook, which can contribute to the overall liquid level. If you’re using a lot of these ingredients, you may need to reduce the amount of added liquid accordingly.
Step-by-Step Guide to Cooking a Roast in the Instant Pot
Let’s walk through a general process for cooking a roast in the Instant Pot, emphasizing the liquid management aspect. This guide can be adapted based on your specific recipe and desired outcome.
Selecting and Preparing the Roast
Choose your desired cut of meat. Chuck roast is a popular choice for its tenderness and flavor when cooked in the Instant Pot. Trim any excess fat, but leave some for flavor. Season the roast generously with salt, pepper, and other desired spices.
Searing the Roast (Optional but Recommended)
Searing the roast before pressure cooking adds a depth of flavor and enhances its texture. Use the “Sauté” function on your Instant Pot. Add a tablespoon or two of oil to the pot and sear the roast on all sides until browned. Remove the roast and set it aside.
Adding Aromatics and Deglazing the Pot
Add chopped onions, garlic, celery, and carrots to the Instant Pot and sauté until softened. This creates a flavorful base for your roast. Deglaze the pot by pouring in a cup of broth or wine and scraping up any browned bits from the bottom. This adds even more flavor to the sauce.
Adding Liquid and the Roast
Place the roast back in the Instant Pot. Add enough liquid (broth, water, or a combination) to reach your desired level of submersion. For a braised effect, aim for partial submersion. For a roasted effect, use a trivet and add liquid just below the trivet line.
Pressure Cooking the Roast
Secure the lid on the Instant Pot and set the pressure valve to “Sealing.” Cook on high pressure for the appropriate amount of time. A general guideline is 20 minutes per pound for chuck roast. Adjust the cooking time based on the size and type of roast.
Natural Pressure Release vs. Quick Release
Once the cooking time is complete, allow the Instant Pot to naturally release pressure for at least 15-20 minutes. This helps prevent the roast from drying out. After the natural pressure release, you can perform a quick release to release any remaining pressure. Be careful of escaping steam.
Shredding or Slicing and Serving
Remove the roast from the Instant Pot and let it rest for a few minutes before shredding or slicing. The resting period allows the juices to redistribute, resulting in a more tender and flavorful roast. Serve with the flavorful sauce from the Instant Pot.
Troubleshooting Common Issues
Even with careful planning, things can sometimes go wrong. Here are some common issues and how to troubleshoot them.
Roast is Dry
If your roast is dry, it could be due to several factors, including overcooking, not enough liquid, or performing a quick pressure release too soon. Try reducing the cooking time, ensuring adequate liquid levels, and allowing for a longer natural pressure release in future attempts.
Roast is Tough
A tough roast usually indicates undercooking. Increase the cooking time and ensure that the roast reaches a safe internal temperature. Tougher cuts of meat benefit from longer cooking times to break down the connective tissues.
Sauce is Too Thin
If the sauce is too thin, you can thicken it using the “Sauté” function after removing the roast. Mix a tablespoon or two of cornstarch with cold water to create a slurry. Add the slurry to the sauce and simmer until thickened. Alternatively, you can use a roux (a mixture of flour and butter) to thicken the sauce.
Burn Notice on the Instant Pot
A “Burn” notice indicates that food is burning on the bottom of the pot. This can happen if there isn’t enough liquid, if food is stuck to the bottom, or if the heat is too high. Immediately turn off the Instant Pot and release the pressure manually. Carefully remove the roast and check the bottom of the pot. Add more liquid and scrape up any stuck-on food before resuming cooking.
Enhancing Flavor and Texture
Beyond liquid management, several techniques can elevate the flavor and texture of your Instant Pot roast. Experiment with different seasonings, marinades, and browning methods to create your signature roast.
Marinating the Roast
Marinating the roast for several hours or overnight can significantly enhance its flavor and tenderness. Use a marinade that contains acidic ingredients like vinegar or citrus juice to help break down the meat fibers.
Adding Flavorful Liquids
Experiment with different liquids to add depth of flavor. Beef broth, chicken broth, vegetable broth, red wine, and even beer can all contribute unique flavors to your roast.
Browning the Roast
As mentioned earlier, searing the roast before pressure cooking adds a rich, caramelized flavor and improves its texture. Don’t skip this step if you have the time.
Using Herbs and Spices
Don’t be afraid to experiment with different herbs and spices. Rosemary, thyme, garlic powder, onion powder, paprika, and chili powder are all excellent choices for seasoning a roast.
Adding Vegetables
Adding vegetables like potatoes, carrots, and onions to the Instant Pot along with the roast creates a complete and satisfying meal. Choose vegetables that can withstand the pressure cooking process without becoming mushy.

FAQ 1: Does a roast always need to be fully submerged in liquid when cooking in an Instant Pot?
No, a roast does not need to be fully submerged in liquid when cooking in an Instant Pot. While adequate liquid is essential for generating the steam required for pressure cooking, covering the roast entirely is not necessary. The steam created by the liquid in the pot will circulate around the roast, cooking it evenly even if the top portion is not immersed.
The amount of liquid needed will vary depending on the size of the roast and the Instant Pot model. Generally, one to two cups of liquid are sufficient to create the necessary steam. Using a trivet also helps to elevate the roast slightly, preventing it from sitting directly in the liquid and promoting even cooking throughout. This method ensures a flavorful and tender roast without requiring complete submersion.
FAQ 2: What happens if I don’t put enough liquid in the Instant Pot with my roast?
Insufficient liquid in your Instant Pot can lead to several issues. The most immediate concern is that the pot won’t reach pressure properly. Without enough liquid to create steam, the Instant Pot may display an error message or simply fail to seal, preventing the cooking process from starting. This can result in a raw or undercooked roast.
Furthermore, if the pot manages to reach pressure with minimal liquid, it risks scorching the bottom of the roast. The food at the base of the pot can burn before the rest of the roast cooks properly. This not only affects the taste and texture of the roast but also makes cleaning the Instant Pot significantly more difficult. Always ensure there’s a sufficient amount of liquid to prevent these problems.
FAQ 3: What are the best liquids to use when cooking a roast in an Instant Pot?
The best liquids to use when cooking a roast in an Instant Pot are those that complement the flavor of the meat. Beef broth or stock is a classic choice, adding richness and depth to the roast. Chicken broth can also be used, especially if you prefer a lighter flavor profile. Vegetable broth is a suitable alternative for those who prefer a vegetarian or vegan option.
Beyond broth, you can also use other flavorful liquids such as wine, beer, or even tomato sauce. Adding a splash of wine or beer can enhance the taste of the roast, while tomato sauce can create a braised effect. Experimenting with different combinations of liquids and herbs can help you create a unique and delicious roast every time. Just remember to consider the overall flavor profile you’re aiming for.
FAQ 4: How does using a trivet affect the liquid requirements for cooking a roast in an Instant Pot?
Using a trivet in the Instant Pot significantly affects the liquid requirements for cooking a roast. A trivet elevates the roast above the liquid, preventing it from sitting directly in it. This allows the steam to circulate more freely around the roast, promoting more even cooking and browning on all sides. As a result, you generally need less liquid when using a trivet compared to cooking the roast directly in the liquid.
When using a trivet, the liquid level only needs to reach below the trivet’s surface. Usually, 1 to 1.5 cups of liquid is sufficient. This ensures that enough steam is generated to cook the roast thoroughly without submerging the meat. The trivet also prevents the roast from becoming waterlogged, preserving its texture and flavor.
FAQ 5: Can I add vegetables to the Instant Pot with the roast, and will that affect the liquid level needed?
Yes, you can absolutely add vegetables to the Instant Pot along with your roast. This is a convenient way to cook a complete meal in one pot. Root vegetables like potatoes, carrots, and onions work particularly well as they can withstand the pressure cooking process without becoming overly mushy. Adding vegetables contributes flavor and nutrients to the cooking liquid and the overall dish.
When you add vegetables, they will release some of their own moisture during cooking, which can slightly increase the overall liquid level in the pot. However, this typically does not drastically change the liquid requirement. It’s still advisable to add the recommended 1 to 2 cups of additional liquid to ensure sufficient steam generation and prevent scorching. Keep in mind that denser vegetables like potatoes absorb more liquid, so consider adjusting the amount accordingly if using a large quantity of such vegetables.
FAQ 6: What happens if I add too much liquid to the Instant Pot when cooking a roast?
Adding too much liquid to the Instant Pot when cooking a roast can lead to a few undesirable outcomes. The most common issue is that the roast might become overly tender and fall apart easily, losing its shape and texture. While tenderness is often desired, too much can result in a mushy consistency that is less appealing. The roast can also taste more boiled than roasted, as it’s essentially braising in a large amount of liquid.
Furthermore, excess liquid can dilute the flavors of the seasonings and the meat itself. The resulting broth might also be less concentrated and flavorful. If you’re planning to use the cooking liquid to make gravy, you may need to reduce it for a longer period to achieve the desired consistency and intensity of flavor. Therefore, it’s best to stick to the recommended amount of liquid to ensure a perfectly cooked and flavorful roast.
FAQ 7: How can I ensure my roast is cooked properly without being fully submerged in liquid in the Instant Pot?
Ensuring your roast is cooked properly without being fully submerged in liquid in the Instant Pot involves a few key steps. First, use a trivet to elevate the roast above the liquid, allowing for even steam circulation. Second, accurately calculate the cooking time based on the weight of the roast. Use a reliable Instant Pot cooking time chart as a guide and adjust as needed.
Finally, always use a meat thermometer to check the internal temperature of the roast. Insert the thermometer into the thickest part of the meat, avoiding bone. Refer to recommended safe internal temperatures for the type of roast you are cooking. If the roast hasn’t reached the desired temperature after the initial cooking time, you can continue cooking in short intervals until it reaches the proper doneness. This will ensure a safe and delicious roast every time.
