Cooking a roast in an Instant Pot pressure cooker can be one of the most rewarding culinary experiences. The tender, juicy meat and flavorful gravies that emerge from this wonder of modern cooking technology not only taste delicious but also save you time in the kitchen. However, achieving that perfect balance of tenderness and flavor requires a good understanding of cooking times, techniques, and the science behind pressure cooking. In this comprehensive guide, we will explore everything you need to know about how long to cook roast in an Instant Pot pressure cooker, along with tips and tricks to elevate your dish to perfection.
Understanding Instant Pot Pressure Cooking
Before diving into specific cooking times for various types of roasts, it’s essential to grasp the concept of pressure cooking. The Instant Pot is a multi-functional appliance that combines several cooking methods, most notably pressure cooking, slow cooking, and sautéing. When pressure cooking, the appliance traps steam inside a sealed pot, which raises the temperature and cooks food more quickly than traditional methods.
The Benefits of Using an Instant Pot for Roasting
Using an Instant Pot for roasting meat comes with numerous benefits:
- Time Efficiency: Pressure cooking dramatically reduces cooking times, allowing you to enjoy a delicious roast in a fraction of the time.
- Flavor Infusion: The sealed environment means that flavors are locked in, resulting in a more flavorful dish.
- Tender Texture: Cooking under pressure creates a tender, juicy roast that is hard to achieve with conventional methods.
Factors Affecting Cooking Time
When determining how long to cook your roast in an Instant Pot, several factors come into play. Understanding these factors can help you achieve the perfect roast every time.
Type of Meat
Different types of meat require varying cooking times. Whether you are making a beef, pork, or lamb roast, it’s crucial to recognize their differences in texture and size.
Weight of the Roast
The size of your roast significantly influences cooking time. Generally, larger roasts take longer to cook. A rule of thumb is to plan for approximately 15 minutes per pound.
Desired Doneness
Your preference for doneness will also affect cooking time. For example, medium-rare will cook faster than well-done. Knowing the ideal temperatures for different levels of doneness is critical.
Natural vs. Quick Release
The method you use to release pressure after cooking influences the final texture of your roast. A natural release can help retain moisture, while a quick release may result in a firmer texture.

Tips for Cooking the Perfect Roast in an Instant Pot
To ensure your roast turns out succulent and flavorful, follow these additional tips:
Brown the Meat First
Searing the roast on the sauté setting before pressure cooking not only locks in flavors but also adds a beautiful caramelized crust. This step is particularly important for larger cuts.
Use Aromatics and Liquids
Adding aromatics like onions, garlic, herbs, and spices can enhance the flavor of your roast. You should also include a liquid, such as broth or wine, to create steam and build pressure. The amount of liquid typically required is about one cup.
Consider Adding Vegetables
To create a complete meal, consider adding vegetables like carrots, potatoes, and celery. These can be added directly in the pot, but remember to adjust cooking times accordingly. Root vegetables generally require less time than the roast.
Check for Doneness
To ensure your roast is cooked to perfection, it’s wise to check its internal temperature using a meat thermometer. For reference, the USDA recommends the following temperatures for different levels of doneness:
- Medium-Rare: 135°F (57°C)
- Medium: 145°F (63°C)
- Well-Done: 160°F (71°C)
Rest Your Meat
Once the cooking time is complete, allow your roast to rest for at least 10-15 minutes before slicing. This lets the juices redistribute, resulting in a more flavorful and moist dish.

What types of roast can I cook in an Instant Pot?
You can cook a variety of roasts in an Instant Pot, including beef, pork, and lamb. Cuts such as chuck roast, brisket, and pork shoulder are particularly well-suited for pressure cooking. The key is to choose cuts with enough marbling as they will become tender and flavorful during the cooking process.
For lamb, options like leg of lamb or lamb shanks work beautifully in an Instant Pot. You can also explore cooking roasts with spices, herbs, and liquids such as broth or wine to enhance the flavor profile of your dish. The versatility of the Instant Pot allows you to experiment with different meats and seasonings.
How long should I cook a roast in an Instant Pot?
Cooking times for roasts in an Instant Pot vary depending on the type of meat and its size. As a general guideline, beef roasts can take anywhere from 60 to 90 minutes for a 3 to 4 lb cut, while pork roasts usually require about 50 to 70 minutes. Always refer to a reliable recipe specific to the cut you’re using for the best results.
It’s important to also allow for natural releasing time after cooking, which can take an additional 10 to 15 minutes. This helps retain moisture and makes the meat more tender. Remember that larger cuts will require more cooking time, so plan accordingly.
Do I need to brown the roast before cooking it?
While it’s not mandatory to brown the roast before cooking, doing so enhances the flavor and creates a beautiful crust. Searing the meat using the ‘Sauté’ function on the Instant Pot allows the Maillard reaction to occur, which adds depth to the overall taste of your dish. It can elevate the flavor profile significantly, making the final outcome more satisfying.
Furthermore, browning also helps to develop fond, which is the browned bits left in the pot. These bits can be deglazed with broth or wine before pressure cooking, which helps build a rich sauce for your roast. Therefore, while not essential, browning is a recommended step for optimal flavor.
Can I cook vegetables with the roast in the Instant Pot?
Yes, you can absolutely cook vegetables alongside your roast in an Instant Pot. Just be mindful of the cooking times for different vegetables, as some may take longer to become tender than others. Root vegetables like potatoes and carrots can be added into the pot, typically cut into larger pieces so they don’t become mushy.
To achieve the best results, it’s advisable to layer them properly in the pot. Place the roast on the bottom and the vegetables on top, allowing them to steam while the roast cooks. This way, your vegetables can soak up the flavors of the meat and broth as they cook, resulting in a delicious one-pot meal.
What liquid should I use for cooking roast in an Instant Pot?
For cooking roast in an Instant Pot, you need to use some form of liquid to create steam and facilitate pressure cooking. Common choices include beef or chicken broth, water, or red wine, each imparting a unique flavor to the meat. Choosing a rich broth or stock is ideal for beef roasts, while lighter liquids may be more suitable for pork or chicken.
Additionally, aromatics such as garlic, onions, or herbs can be added to the liquid to enhance the flavor even further. The liquid will also become a base for gravy or sauce when the cooking is complete, making it a vital component of your roast preparation.
How do I know when my roast is done cooking?
The best way to determine if your roast is done cooking is by using an instant-read meat thermometer. For beef roasts, the internal temperature should reach at least 145°F for medium-rare or higher depending on your preference. For pork, it should reach a minimum of 145°F, while lamb should be cooked to an internal temperature of 135°F for medium-rare.
After removing the roast from the Instant Pot, allow it to rest for about 10 to 15 minutes before slicing. This resting period allows the juices to redistribute, ensuring a tender and juicy roast. Always double-check the temperature of the thickest part of the meat to confirm it has reached a safe and desired level of doneness.
What should I do if my roast is tough after cooking?
If your roast turns out tough after cooking, it’s likely that it either needed more time or the cut of meat you used was too lean. Tough cuts, such as those from the shoulder or shank, often require longer cooking times to break down the connective tissues and become tender. Consider placing it back in the Instant Pot, adding a bit more liquid, and then cooking it on high pressure for an additional 10 to 20 minutes.
Another factor to consider is how you sliced the meat. Always cut against the grain to ensure the pieces are tender and easier to chew. If the issue persists, you might also use the shredded meat in other dishes, such as tacos or sandwiches, where the texture may be less noticeable.
