Pot roast has always been the classic Sunday dinner. My grandma cooked it almost every week while my mom was growing up, and my mom made sure it was on our table regularly while I was growing up.

Over a decade ago, my mom and I decided to upgrade our tradition by making it in our Instant Pot. 

The result? Tender, juicy pot roast on the table in less than half the time it would take in the oven or on the stovetop.

Enjoy this comfort food any day you want a special supper—without spending hours in the kitchen!

Why Cook Pot Roast in the Instant Pot?

I love to use my Instant Pot to make pot roast! 

The steam and high-pressure cooking also helps tough cuts of meat cook up tender in much less time than they require on the stove. 

Plus, using the Saute setting makes it easy to brown the meat without dirtying an extra dish and keeps all the rich, savory flavor in the pot to flavor the gravy.

What meat to use for Pot Roast? 

Make sure you use a well-marbled (aka “fattier) cut of beef. Nicely marbled meats have fat-soluble flavor compounds that get evenly distributed as the fat breaks down during cooking. 

Look for cuts with “chuck” in the name and cross rib roast. You can buy boneless or trim off the bone before cooking. 

❤️ Chuck roast is my go-to cut for pot roast because: 

  • It’s less expensive and usually in stock
  • Often on sale
  • Its shape is easy to brown evenly in the pressure cooker

Avoid leaner cuts, which tend to be dryer with less flavor, including:

  • Ribeye roast
  • Eye of round roast
  • Bottom round rump roast 
  • Tri-tip roast
  • Top blade 
  • Cuts with “steak,” “sirloin,” or “tenderloin” in the name 

Sliced or Shredded: Which Do You Prefer?

People have strong opinions when it comes to pot roast texture! Some like it so tender it falls apart and shreds easily. Others prefer it sliceable but still tender. 

This recipe strikes a happy medium—fork-tender but holds together well enough to slice.

If you prefer your roast ultra shreddable, add another 5 to 10 minutes to the cook time and another 5 minutes to the natural pressure release. This allows the collagen in the meat to break down more thoroughly, resulting in fall-apart, melt-in-your-mouth texture.

💡 A handy tip: Use an instant-read thermometer to check the roast’s internal temperature. For ideal tenderness, aim for 200°F in the thickest part—this ensures the tough connective tissue has softened perfectly.

Why Cut the Roast Into Thirds?

Cutting your chuck roast into three smaller pieces isn’t just for convenience—it actually helps the meat cook faster and more evenly. 

Pressure cooking times depend more on thickness than total weight. Smaller pieces mean the heat penetrates the meat’s center more quickly, reducing overall cooking time.

Plus, cutting the roast helps it fit more easily in your Instant Pot and allows for more even browning. 

If you prefer to cook a whole roast, try my Classic Pot Roast and Potatoes recipe, which requires a longer cook time and natural release.

To get the most tender slices, always cut your roast against the grain (aka the direction the muscle fibers run). Cutting against it shortens those fibers, making each bite easier to chew and more tender.

Why the second cook time for potatoes and carrots?

I don’t pressure cook the potatoes and carrots with the meat because potatoes cook much faster than beef and will become mushy if cooked for the full time.

Instead, after the roast is done, I cook the potatoes and carrots separately in the flavorful cooking liquid. This method lets the vegetables soak up the beefy goodness without overcooking.

If you want to cook the veggies with the roast, some readers like to wrap the potatoes and carrots tightly in aluminum foil and place the packet on top of the meat. The foil slows the cooking time, preventing mushiness.

You can also double or triple the number of potatoes you add without changing the cook time. (Try to use potatoes about the same size.) If you do double the potatoes, know that it will take longer for the pot to come to pressure.

How to make roast and gravy

In my family, pot roast isn’t complete without a generous helping of gravy!

So this pressure cooker recipe makes a BIG batch of gravy to satisfy even the hungriest appetites.

If you prefer less gravy, you can reduce the liquid to 2 cups of water and 2 teaspoons of beef base, and cut the flour slurry ingredients in half.

Flour vs. Cornstarch for Thickening

For this pot roast gravy, I prefer to thicken with flour. (Wondra flour works best if you have it on hand, but regular all-purpose is great too.) 

Flour gives the gravy a rich flavor and a satisfying texture. When using flour, whisk it with cold water to make a slurry, then add it gradually to the hot broth. Bring the gravy to a boil and maintain the boil for at least 2 minutes to cook out any raw flour taste.

However, if you prefer cornstarch, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water, then stir it into the hot cooking liquid and bring to a boil to activate the thickener. Use more if desired, but keep in mind that the gravy will continue to thicken as it cools.

Serving Suggestions

Pot roast with potatoes and carrots is the classic combo, and this recipe includes small potatoes and carrots to make a complete meal. 

If you prefer mashed potatoes, it’s easy to steam them over the cooking liquid instead. For best results, use a steamer basket that keeps the potatoes suspended over the roast juices so the potatoes absorb extra flavor.

Also, Yorkshire Pudding is a MUST-HAVE with roast. I love making it in muffin tins or a popover pan so everyone gets their own crispy, individual servings.

How to Store Leftovers

If I have leftovers, I like to cut the remaining beef and store it directly in the gravy in an airtight container. Store the vegetables separately in another container. Place in the refrigerator for up to 4 days or freeze for up to 4 months. 

To reheat, I like to let the roast and gravy thaw in the fridge overnight. Then transfer to a sauce pan and reheat until hot. Serve over mashed potatoes or egg noodles. 

Recipe variation

Do you like mushrooms with your roast? I like to prepare them according to step 6 in our Beef Stroganoff recipe and add them just before serving.

Old-Fashioned Pressure Cooker Pot Roast

Yield: 8 servings
Prep Time: 5 minutes
Cook Time: 50 minutes
Additional Time: 30 minutes
Total Time: 1 hour 25 minutes

This Pressure Cooker Pot Roast recipe combines beef roast, broth, new potatoes, and chopped carrots to create hearty, flavorful, old-fashioned comfort food.

Ingredients

  • 3 pounds beef chuck roast, about 2.5 inches thick, cut into 3 equal pieces
  • Salt and freshly ground pepper, for seasoning
  • 1 tablespoon vegetable oil
  • 2/3 cup diced onion (I used frozen)
  • 3 1/2 cups water*
  • 3 teaspoons beef base or 3 beef bouillon cubes*
  • 1 tablespoon tomato paste
  • 1 bay leaf
  • About 10 small new potatoes, optional
  • 3 large carrots, cut into 2-inch pieces, optional
  • 1/2 cup all-purpose flour (we prefer Wondra)
  • 1/2 cup cold water

Instructions

Prepare & Pressure Cook the Beef:

  1. Pat the roast dry with paper towels. Season both sides of the roast well with salt and pepper.
  2. Select Sauté and preheat the pressure cooking pot. When hot, add the vegetable oil. Add the three pieces of roast to the cooking pot so that they lay flat in the pot. Cook until the beef is browned and releases easily from the pot, about 5 minutes. Transfer to a plate.
  3. Add the onion to the cooking pot. Sauté for about 3 minutes until tender, stirring occasionally to scrape up any browned bits from the bottom of the pot.
  4. Stir in the 3 1/2 cups water and beef base or bouillon,* tomato paste, and bay leaf.
  5. Return the roast and any accumulated juices to the pot. Lock the lid in place. Select High Pressure and 50 minutes cook time.
  6. When the cook time ends, turn off the pressure cooker. Let the pressure release naturally for 10 minutes, then use a quick release to release any remaining pressure.
  7. When the valve drops, carefully remove the lid. Transfer the roast to a cutting board and cover with aluminum foil.

If you wish to cook potatoes and carrots with this meal, proceed with this section; otherwise, skip to the gravy:

  1. Add potatoes and carrots directly to the juices remaining in the cooking pot. Lock the lid in place. Select High Pressure and 3 minutes cook time.
  2. When the cook time ends, turn off the pressure cooker. Use a quick pressure release. When the valve drops, carefully remove the lid. Check the potatoes for doneness. If needed, select Sauté and simmer in the juices until potatoes reach your desired tenderness.
  3. Use a slotted spoon to transfer the potatoes and carrots to a serving bowl and sprinkle with parsley. Cover with foil until ready to serve.

Finish the Gravy:

  1. Pour the juices in the cooking pot through a mesh strainer into a fat separator. (You can skip the strainer if you like onions in your gravy. Be sure to remove the bay leaf, though!) Skim off any excess fat. Return the juices to the cooking pot.
  2. In a small bowl, whisk together the flour and 1/2 cup cold water until smooth. Add ½ cup hot cooking juices to the flour mixture and stir to combine. Add the slurry to the pot, stirring constantly. Select Sauté and bring the gravy to a boil, stirring constantly until it thickens. Taste the gravy and season with salt and pepper to taste.
  3. To serve, cut the roast into pieces and place on a rimmed serving platter. Ladle half the gravy over the roast and pour the rest of the gravy into a gravy boat to serve with the potatoes and carrots.

Notes

* As written, this recipe makes lots of extra gravy. If you’d prefer to make less gravy, reduce the liquid to 2 cups water and 2 teaspoons beef base. You’ll also want to reduce the flour and cold water to 1/4 cup of each. You can also use 3 1/2 cups beef broth in place of the bouillon and water.

** The total time to make this recipe will be 10 minutes shorter if you don't cook the potatoes and carrots.
