Grilling season is upon us, and the aroma of smoky deliciousness fills the air. But before you fire up the grill and start cooking, you might be wondering about the versatility of your cookware. Can you use that beautiful stoneware you love so much on the grill? The answer isn’t a simple yes or no. It depends on various factors, and understanding them is crucial for both successful grilling and preserving your precious stoneware.
Understanding Stoneware and Its Properties
Stoneware is a type of pottery fired at relatively high temperatures, typically between 2,100 and 2,300 degrees Fahrenheit (1,100 to 1,300 degrees Celsius). This high-firing process results in a dense, non-porous, and durable material. Its strength and heat retention properties make it a popular choice for baking dishes, casseroles, and serving ware.
The Composition of Stoneware
Stoneware is primarily made from clay, but the specific type of clay and the addition of other minerals influence its final characteristics. Different stoneware formulations have varying tolerances to thermal shock, which is the rapid change in temperature that can cause cracking or shattering.
Heat Resistance and Thermal Shock
While stoneware is known for its heat resistance, it’s not indestructible. The key concern when using stoneware on a grill is thermal shock. Grills can reach extremely high temperatures very quickly, creating a drastic temperature difference between the stoneware and its environment. This sudden change can cause the stoneware to crack, especially if it’s not designed to withstand such extreme conditions.
Factors to Consider Before Grilling with Stoneware
Before placing your stoneware on the grill, carefully consider the following factors:
Manufacturer’s Instructions
This is the most important step. Always consult the manufacturer’s instructions or the product description. Many stoneware pieces are specifically designed for oven use and may not be suitable for direct exposure to grill flames or extremely high temperatures. Some manufacturers may explicitly state whether their stoneware is grill-safe. If you can’t find specific instructions, err on the side of caution.
Type of Grill
The type of grill you’re using significantly impacts the heat distribution.
Gas Grills
Gas grills offer more precise temperature control compared to charcoal grills. This makes them a slightly safer option for using stoneware, as you can gradually increase the heat and avoid sudden temperature spikes. However, direct flame impingement is still a risk.
Charcoal Grills
Charcoal grills produce intense heat and can be difficult to regulate precisely. The uneven heat distribution and high temperatures make charcoal grills riskier for stoneware. Using stoneware on a charcoal grill greatly increases the chance of thermal shock.
Ceramic Grills (Kamado)
Ceramic grills, like the Big Green Egg, are known for their excellent heat retention and insulation. While they maintain consistent temperatures, the intensity can still pose a threat to stoneware. Use caution and consider indirect grilling methods.
Indirect vs. Direct Heat
Direct heat exposes the stoneware directly to the flames or heat source. This is generally not recommended, as it increases the risk of thermal shock. Indirect heat, where the stoneware is placed away from the direct flame and exposed to circulated hot air, is a much safer approach. This allows the stoneware to heat more gradually and evenly.
The Thickness of the Stoneware
Thicker stoneware is generally more resistant to thermal shock than thinner pieces. The thicker material can better withstand temperature fluctuations without cracking. However, even thick stoneware can be damaged by extreme temperature changes.
The Age and Condition of the Stoneware
Older stoneware or pieces with existing cracks or chips are more susceptible to damage from heat. Even minor imperfections can weaken the structural integrity of the stoneware and make it more likely to crack under stress. Inspect your stoneware carefully for any signs of damage before using it on the grill.
Safe Practices for Using Stoneware on the Grill
If you decide to use stoneware on the grill, follow these guidelines to minimize the risk of damage:
Preheating Gradually
Avoid placing cold stoneware directly onto a hot grill. Preheat the stoneware gradually, starting with a low temperature and slowly increasing it over time. This allows the stoneware to adjust to the heat gradually and reduces the risk of thermal shock.
Using Indirect Heat
Always use indirect heat whenever possible. Create a barrier between the stoneware and the direct flames. On a gas grill, turn off the burner directly under the stoneware. On a charcoal grill, arrange the coals to the sides of the stoneware.
Monitoring Temperature
Closely monitor the temperature of the grill. Avoid exceeding the maximum temperature recommended by the stoneware manufacturer. Use a grill thermometer to accurately track the temperature.
Avoiding Sudden Temperature Changes
Avoid adding cold liquids or ingredients to hot stoneware, as this can cause thermal shock. Let the stoneware cool down gradually after grilling before washing it.
Seasoning the Stoneware
Seasoning stoneware can help to increase its durability and prevent food from sticking. Seasoning involves coating the stoneware with oil and baking it at a low temperature. Over time, the oil will polymerize and create a non-stick surface.
Alternatives to Stoneware for Grilling
If you’re unsure about using your stoneware on the grill, consider these safer alternatives:
Cast Iron
Cast iron is incredibly durable and can withstand extremely high temperatures. It’s an excellent choice for grilling, searing, and baking. Cast iron distributes heat evenly and retains heat well, making it ideal for achieving a perfect sear.
Grill Baskets
Grill baskets are designed specifically for grilling delicate foods like vegetables and seafood. They allow you to cook these items without them falling through the grates.
Aluminum Foil
Aluminum foil can be used to create a barrier between the food and the grill grates. It’s a versatile option for grilling fish, vegetables, and other delicate items.
Grilling Stones
Grilling stones, typically made from ceramic or cordierite, are designed specifically for grilling pizzas and other flatbreads. They can withstand high temperatures and provide even heat distribution.
Cleaning Stoneware After Grilling
Cleaning stoneware after grilling requires a gentle approach to avoid damaging the surface.
Cooling Down Completely
Allow the stoneware to cool down completely before washing it. Never plunge hot stoneware into cold water, as this can cause it to crack.
Gentle Cleaning
Use warm water and a mild dish soap to clean the stoneware. Avoid using abrasive cleaners or scouring pads, as they can scratch the surface.
Removing Stubborn Residue
For stubborn residue, try soaking the stoneware in warm water with baking soda. You can also use a plastic scraper to gently remove stuck-on food.
Avoiding Dishwashers
While some stoneware is dishwasher-safe, it’s generally best to hand-wash it to prolong its lifespan. The harsh detergents and high temperatures in dishwashers can damage the surface of the stoneware.
Conclusion
While it might be tempting to use your stoneware on the grill for that perfect smoky flavor, it’s crucial to proceed with caution. Always prioritize safety and consult the manufacturer’s instructions. Consider the type of grill, the thickness and condition of the stoneware, and use indirect heat whenever possible. If you’re unsure, opt for a safer alternative like cast iron or a grill basket. By understanding the properties of stoneware and following safe grilling practices, you can minimize the risk of damage and enjoy delicious grilled meals. Remember, the best approach is to prioritize the longevity of your cookware while exploring the possibilities of outdoor cooking.
Can all types of stoneware be used on the grill?
Not all stoneware is created equal, and not all types are suitable for grilling. The crucial factor is the stoneware’s heat resistance and its ability to withstand rapid temperature changes. Stoneware designed for oven use, often labeled as oven-safe, is generally more likely to withstand the heat of a grill than decorative pieces or those meant for serving only.
Look for stoneware specifically designated as grill-safe or flameproof. These pieces are typically made with a higher clay content and are fired at higher temperatures, resulting in a more durable and heat-resistant product. Always check the manufacturer’s instructions before using any stoneware on the grill to avoid damage or cracking.

Stoneware offers excellent heat retention, distributing heat evenly across its surface. This even heating helps to prevent hot spots and ensures your food cooks uniformly, minimizing the risk of burning. It also retains heat for a longer period, keeping your food warm for serving.
Beyond even cooking, stoneware provides a unique cooking surface that can impart a subtle smoky flavor to your food. This is especially true if you preheat the stoneware on the grill before placing your food on it. The porous nature of some stoneware allows it to absorb flavors from the grill, enhancing the overall taste of your meal.
What are the potential risks of using stoneware on the grill?
The primary risk is thermal shock, which occurs when stoneware experiences a rapid and significant temperature change. This can cause the stoneware to crack or even shatter. Placing cold stoneware directly onto a hot grill is a surefire way to induce thermal shock, as is adding cold liquids to hot stoneware.
Another risk is that some stoneware glazes may not be food-safe at high temperatures. While most modern glazes are lead-free and safe for oven use, it’s important to verify that your stoneware is explicitly labeled as safe for grill use. Using stoneware with unsafe glazes could potentially leach harmful chemicals into your food.
How should I prepare my stoneware before using it on the grill?
The most important step is to preheat the stoneware gradually. Start by placing the stoneware on the grill while it’s still cold or at a low temperature. Slowly increase the heat to your desired cooking temperature, allowing the stoneware to warm up evenly. This minimizes the risk of thermal shock.
If you’re using the stoneware for the first time, consider seasoning it lightly with cooking oil. This can help prevent food from sticking and also creates a protective layer that enhances its durability. Ensure the stoneware is completely dry before placing it on the grill, as any moisture can also contribute to cracking.
What types of food are best suited for cooking on stoneware on the grill?
Stoneware is particularly well-suited for cooking delicate foods that might otherwise fall through the grates or stick to the grill. Vegetables, seafood, and smaller cuts of meat are excellent choices. Think about grilling sliced vegetables like zucchini or peppers, fish fillets, or even making individual pizzas directly on the stoneware.
It’s also ideal for foods that benefit from indirect heat. By placing the stoneware on one side of the grill and the heat source on the other, you can create an oven-like environment for roasting or baking. This is great for cooking larger cuts of meat, baking desserts, or preparing casseroles.
How do I clean stoneware after using it on the grill?
Allow the stoneware to cool completely before attempting to clean it. Introducing cold water to hot stoneware can cause it to crack. Once cooled, avoid using harsh abrasive cleaners or steel wool, as these can scratch the surface and damage the glaze. A gentle dish soap and a soft sponge or cloth are usually sufficient.
For stubborn food residue, try soaking the stoneware in warm, soapy water for a few minutes before scrubbing. Baking soda can also be used as a gentle abrasive to remove difficult stains. Avoid placing stoneware in the dishwasher, as the harsh detergents and high temperatures can shorten its lifespan and damage the finish.
