Perfect Instant Pot Beef Roast: Cooking Times & Tips

Looking to make a juicy, tender beef roast in your Instant Pot but not sure how long to cook it? You’re in the right place! The Instant Pot is a game-changer for home cooks, turning tough cuts of beef into melt-in-your-mouth roasts in a fraction of the time it takes in the oven or slow cooker. In this guide, we’ll break down everything you need to know about cooking beef roast in your Instant Pot—from choosing the right cut and setting the timer, to adding veggies and ensuring perfect results every time.

Why Use an Instant Pot for Beef Roast?

The Instant Pot is a pressure cooker that speeds up cooking by using high pressure and steam. This means you can enjoy a flavorful, fork-tender beef roast in just over an hour, instead of waiting all day. Plus, it’s a one-pot meal—less mess and less fuss!

Choosing the Right Cut of Beef

Not all beef roasts are created equal when it comes to pressure cooking. Here are some of the best cuts for your Instant Pot:

• Chuck Roast: Rich in flavor and marbled with fat, this cut becomes incredibly tender under pressure.
• Brisket: Known for its robust taste, brisket does well with longer cook times.
• Rump Roast: Leaner than chuck but still delivers great results.
• Round Roast: Another lean option that benefits from pressure cooking to avoid dryness.

For best results, choose a roast between 2 to 4 pounds. Larger roasts may require more time and could become dry if overcooked.

How Long to Cook Beef Roast in the Instant Pot

The key to a perfect beef roast is timing. Here’s a quick reference for common roast sizes:

• For a 2-pound roast: Cook on high pressure for 45-50 minutes, with a natural release for 15-20 minutes.
• For a 3-pound roast: Cook on high pressure for 60-65 minutes, with a natural release for 15-20 minutes.
• For a 4-pound roast: Cook on high pressure for 75-80 minutes, with a natural release for 15-20 minutes.

The natural release is important—it lets the juices redistribute so your roast stays moist and flavorful.

Step-by-Step: Cooking Beef Roast in the Instant Pot

1. Season Your Roast: Generously sprinkle salt, pepper, garlic powder, and any other favorite seasonings all over the beef.
2. Sear the Meat: Turn your Instant Pot to “Sauté.” Add a tablespoon of oil and brown the roast on all sides. This step adds depth of flavor but is optional if you’re short on time.
3. Add Liquid: Pour in at least 1 cup of beef broth or water. The Instant Pot needs liquid to build pressure and prevent burning.
4. Add Aromatics & Veggies (Optional): Toss in onions, carrots, potatoes, garlic, or herbs for extra flavor and a complete meal.
5. Pressure Cook: Secure the lid, set the valve to sealing, and cook according to your roast’s size (see timing above).
6. Natural Release: Let the pressure release naturally for at least 15-20 minutes before opening the lid. This helps keep the meat juicy.
7. Rest & Serve: Remove the roast, let it rest for a few minutes, then slice against the grain. Serve with veggies and pan juices or make a quick gravy!

Tips for the Best Instant Pot Beef Roast

• Sear for Flavor: Browning the meat first adds rich flavor and helps seal in juices.
• Add Enough Liquid: Always use at least 1 cup of liquid to avoid a burn notice and ensure proper pressure.
• Don’t Skip Natural Release: Quick-releasing pressure can make meat tough; natural release keeps it tender.
• Add Veggies Later: If you like firmer veggies, add them halfway through cooking or after releasing pressure and cook for an additional 5 minutes.
• Use a Meat Thermometer: For perfect doneness, check that your roast reaches an internal temperature of at least 145°F (medium rare) or up to 160°F (medium).

Flavor Variations & Add-Ins

The classic beef roast is delicious on its own, but you can easily switch up the flavors. Try these add-ins:

• Red wine: Replace half the broth with wine for depth.
• Fresh herbs: Rosemary, thyme, or bay leaves boost aroma.
• Balsamic vinegar or Worcestershire sauce: Adds tang and complexity.

Troubleshooting: Common Questions & Solutions

• The roast is tough: It probably needs more cooking time. Return it to the pot and cook for another 10-15 minutes under pressure.
• The roast is dry: This can happen if it’s overcooked or too lean. Next time, try a fattier cut or reduce cook time slightly.
• The veggies are mushy: Add vegetables later in the process or cook them separately to keep them firm.

Serving Suggestions

Your beef roast pairs perfectly with classic sides like mashed potatoes, roasted vegetables, or crusty bread. Don’t forget to use those delicious pan juices as a sauce—or thicken them into gravy with a bit of cornstarch slurry!

Storing & Reheating Leftovers

• Refrigerate: Store leftover beef and veggies in an airtight container in the fridge for up to 4 days.
• Freeze: Beef roast freezes well; slice it and store in freezer bags for up to 3 months.
• Reheat: Warm gently in the microwave or on the stovetop with a splash of broth to keep it moist.

FAQs About Cooking Beef Roast in Instant Pot

Can I cook frozen beef roast in the Instant Pot?

Yes! You can cook a frozen beef roast directly in your Instant Pot—just add about 20-30 extra minutes to your usual cook time. You won’t be able to sear it first, but it will still turn out tender and delicious.

How much liquid should I use?

The Instant Pot requires at least 1 cup of liquid to build pressure. For extra flavor, use beef broth instead of water. Add more if you’re including lots of veggies or want extra sauce.

Do I need to let my roast rest before slicing?

Absolutely! Letting your beef roast rest for about 10 minutes after cooking helps retain its juices and makes slicing easier.

Can I make gravy from the cooking liquid?

You sure can! After removing the meat and veggies, turn your Instant Pot to “Sauté.” Mix a tablespoon of cornstarch with two tablespoons of water, whisk into the juices, and simmer until thickened.
