Pressure cookers have revolutionized cooking, offering speed and efficiency that traditional methods simply can’t match. However, with this powerful appliance comes a need for caution and understanding of which materials are safe to use. One common question that arises is: Can you use parchment paper in a pressure cooker? The answer, while seemingly simple, requires a nuanced exploration of the science behind pressure cooking and the properties of parchment paper.
Understanding Pressure Cooking
Pressure cooking is a method of cooking in a sealed vessel that doesn’t allow air or liquids to escape below a preset operating pressure. In essence, it cooks food by steam under pressure. The increased pressure raises the boiling point of water, allowing food to cook at a higher temperature than it would in a regular pot. This higher temperature significantly reduces cooking time.
The key to pressure cooking is the airtight seal. This seal traps the steam generated by the boiling liquid inside the pot, creating a pressurized environment. This pressure forces moisture into the food, resulting in tender and flavorful dishes in a fraction of the time.
There are two main types of pressure cookers: stovetop and electric. Stovetop pressure cookers require manual adjustment of the heat source, while electric pressure cookers, like the popular Instant Pot, are automated and offer pre-programmed settings for various types of food. Regardless of the type, the principle remains the same: cooking with pressurized steam.
The Properties of Parchment Paper
Parchment paper, also known as baking paper, is a cellulose-based paper that has been treated to make it non-stick, grease-resistant, and heat-resistant. Unlike wax paper, parchment paper can withstand high temperatures without melting or sticking to food. It’s commonly used in baking to line baking sheets, preventing cookies and cakes from sticking and making cleanup easier.
Parchment paper’s heat resistance comes from a process called parchmentizing. This process involves passing the paper through a bath of sulfuric acid, which partially dissolves the cellulose and creates a dense, non-porous surface. This treatment gives parchment paper its characteristic strength and heat resistance.
However, it’s crucial to note that parchment paper is not fireproof. While it can withstand oven temperatures up to a certain limit (usually around 420-450°F or 215-230°C), it will eventually burn if exposed to direct flame or excessive heat. This is a critical consideration when using it in a pressure cooker.
Parchment Paper in a Pressure Cooker: Is it Safe?
The question of whether you can safely use parchment paper in a pressure cooker depends on how it’s used and the specific type of pressure cooker. In general, using parchment paper in a pressure cooker is considered safe under certain conditions, but it’s essential to understand the risks and limitations.
The primary concern is the potential for the parchment paper to block the pressure release valve or interfere with the sealing mechanism of the pressure cooker. If the paper is not properly positioned or if it’s used in excessive amounts, it could prevent the cooker from reaching the correct pressure or cause it to malfunction.
Safe Uses of Parchment Paper in Pressure Cookers
When used correctly, parchment paper can be a helpful tool in pressure cooking. Here are some safe and common applications:
- As a Sling: Parchment paper can be used to create a sling for lifting delicate foods out of the pressure cooker. This is particularly useful for cheesecakes, pot roasts, or other items that might fall apart when lifted directly. Simply cut a large circle of parchment paper, place the food in the center, and use the overhanging edges to lift the food out after cooking. Ensure the edges don’t obstruct the vent or sealing ring.
- Separating Layers: Parchment paper can be used to separate layers of food in the pressure cooker, preventing them from sticking together. This is useful when cooking multiple items at once, such as vegetables and meat. Cut the parchment paper to fit inside the pot and place it between the layers of food.
- As a Barrier: Using parchment paper as a barrier is helpful when cooking delicate fish or other foods that tend to stick to the bottom of the pot. Line the bottom of the pressure cooker with parchment paper before adding the food.
- In Pot-in-Pot (PIP) Cooking: Parchment paper can be used inside a smaller, oven-safe dish when using the pot-in-pot cooking method. This method involves placing the smaller dish inside the pressure cooker on a trivet, with water in the bottom of the main pot. The parchment paper helps prevent food from sticking to the smaller dish.
Risks and Precautions
While parchment paper can be used safely in a pressure cooker, it’s essential to be aware of the potential risks and take necessary precautions.
- Avoid Blocking Vents: The most critical precaution is to ensure that the parchment paper does not block the pressure release valve or the sealing ring. Blocking these components can prevent the pressure cooker from working correctly and could potentially lead to a dangerous situation.
- Use High-Quality Parchment Paper: Use only high-quality, food-grade parchment paper that is specifically designed for baking. Avoid using wax paper or other types of paper, as they can melt or release harmful chemicals when exposed to high heat.
- Don’t Overfill the Cooker: Avoid using excessive amounts of parchment paper, as this can interfere with the circulation of steam inside the pressure cooker. Overfilling can also prevent the cooker from reaching the correct pressure.
- Monitor the Cooking Process: Always monitor the cooking process carefully, especially when using parchment paper for the first time. If you notice any unusual noises or smells, stop the cooking process immediately and allow the pressure to release naturally.
- Check Manufacturer’s Instructions: Always consult the manufacturer’s instructions for your specific pressure cooker model before using parchment paper. Some manufacturers may have specific recommendations or warnings regarding the use of parchment paper.
Alternatives to Parchment Paper
If you’re concerned about using parchment paper in your pressure cooker, there are several safe and effective alternatives.
- Silicone Baking Mats: Silicone baking mats are a reusable and heat-resistant alternative to parchment paper. They can withstand high temperatures and are non-stick, making them ideal for lining the bottom of the pressure cooker or using as a sling.
- Aluminum Foil: Aluminum foil can be used in a pressure cooker, but it’s essential to use it carefully. Ensure that the foil does not block the pressure release valve or the sealing ring. Foil is best used for wrapping food or lining the bottom of the pot.
- Oven-Safe Dishes: Oven-safe dishes, such as glass or ceramic bowls, can be used inside the pressure cooker for pot-in-pot cooking. This eliminates the need for parchment paper altogether.
- Trivets: A trivet is a metal or silicone stand that elevates food above the bottom of the pressure cooker. This prevents food from sticking and allows for even cooking.
Practical Examples
To illustrate the safe and effective use of parchment paper in a pressure cooker, consider these practical examples:
- Cheesecake: When making a cheesecake in a pressure cooker using the pot-in-pot method, line the bottom of the springform pan with parchment paper to prevent sticking and make it easier to remove the cheesecake after cooking. Create a parchment paper sling to lift the pan out of the pressure cooker safely.
- Pot Roast: When cooking a pot roast in a pressure cooker, place a large sheet of parchment paper on the bottom of the pot before adding the roast. This will prevent the roast from sticking and make it easier to clean the pot afterward. You can also create a sling for easy removal.
- Salmon: When steaming salmon in a pressure cooker, place the salmon fillets on a piece of parchment paper before placing them on the trivet. This will prevent the salmon from sticking to the trivet and make it easier to remove the cooked fillets.

Yes, you can generally use parchment paper in a pressure cooker, but with certain precautions. It’s often used to create a barrier between the food and the inner pot, especially when cooking delicate items or ingredients that tend to stick. Ensure the parchment paper is adequately sized and does not obstruct the pressure release valve or completely cover the bottom, hindering even heat distribution.
However, parchment paper alone cannot withstand extremely high temperatures or prolonged exposure to moisture for extended durations. It is not intended to completely replace trivets or other pressure cooking accessories used to raise items above the bottom of the pot. Consider combining it with other methods for optimal results.
What are the benefits of using parchment paper in a pressure cooker?
Using parchment paper in a pressure cooker offers several benefits. It helps prevent food from sticking to the bottom of the pot, making cleanup much easier. It also reduces the need for excessive oil or fat when cooking, making it a healthier alternative.
Furthermore, parchment paper can create a makeshift “sling” to easily lift food items out of the pressure cooker once they’re cooked, especially for delicate dishes like cheesecakes or roasts. It also helps keep flavors separate when layering different ingredients during the cooking process.
Are there any risks associated with using parchment paper in a pressure cooker?
One potential risk is that if the parchment paper is not cut correctly or placed properly, it can block the pressure release valve. This could lead to dangerous pressure build-up inside the cooker. Always make sure the valve is clear and unobstructed.
Another risk involves the potential for the parchment paper to degrade or tear during the cooking process, especially with longer cooking times or when exposed to excessive moisture. Consider using a thicker, higher-quality parchment paper or combining it with other techniques for added safety and performance.
What type of parchment paper should I use in a pressure cooker?
Ideally, you should use parchment paper specifically labeled as “oven-safe” or “baking parchment,” as these are designed to withstand high temperatures. Ensure the packaging states a temperature rating higher than your pressure cooker’s operating temperature, typically around 250°F (121°C).
Avoid using wax paper, as the wax coating can melt and potentially contaminate your food or damage your pressure cooker. Brown parchment paper, which is unbleached, is generally considered a safer and more environmentally friendly option compared to bleached white parchment paper.
How do I properly line a pressure cooker with parchment paper?
To line a pressure cooker with parchment paper, first measure the diameter of the inner pot’s base. Cut a circle of parchment paper slightly larger than this diameter. You can also cut strips of parchment paper to line the sides of the pot, overlapping them slightly for full coverage.
Ensure the parchment paper doesn’t cover the pressure release valve or the sealing ring. It should fit snugly against the bottom and sides without excessive overhang. For easier lifting, you can create a sling by cutting two long strips, placing them perpendicular to each other underneath the food before cooking, and using the ends to lift it out.
Can parchment paper affect the cooking time in a pressure cooker?
In most cases, using parchment paper shouldn’t significantly affect the cooking time in a pressure cooker. Pressure cookers rely on steam and pressure, and the thin layer of parchment paper generally doesn’t act as a substantial insulator.
However, if you’re using a very thick layer of parchment paper or if it covers a large portion of the food’s surface, it might slightly impede heat transfer. In such cases, you might need to add a minute or two to the cooking time, but this is usually minimal and requires adjusting based on your specific recipe.
Is there an alternative to using parchment paper in a pressure cooker?
Yes, there are several alternatives to using parchment paper in a pressure cooker. A common alternative is using a silicone baking mat or liner, which is reusable and can withstand high temperatures. These are readily available in various shapes and sizes.
Another option is to use a trivet or steamer basket to elevate the food above the bottom of the pot, preventing it from sticking and ensuring even cooking. You can also use a light coating of cooking oil or spray directly on the bottom of the pot, although this might not be suitable for all recipes or dietary needs.
