What Pressure to Cook Beef Stew in Instant Pot

The correct pressure for cooking beef stew in an Instant Pot is High Pressure, which equates to 10-12 psi (pounds per square inch). This high-pressure setting is essential to break down tough collagen in beef chuck or brisket within 35-45 minutes, yielding fork-tender meat and a rich broth. Low pressure (5-7 psi) is not recommended as it will not achieve the same tenderness in a reasonable time.

Quick Answer

For beef stew, always use High Pressure. The standard cooking time is 35-45 minutes at high pressure, followed by a 10-15 minute natural pressure release (NR). Quick release can toughen the meat and cause splattering.

Pressure Level: High Pressure (10-12 psi) is the only effective setting for beef stew.
Cooking Time: 35-45 minutes at High Pressure for 1-inch beef cubes; larger chunks need up to 50 minutes.
Release Method: Natural release for at least 10 minutes helps retain moisture and tenderness.
Meat Type: Chuck, brisket, or round cuts work best; avoid lean cuts like sirloin.

Why High Pressure Is Necessary for Beef Stew

Beef stew relies on tough, collagen-rich cuts like chuck or brisket. These cuts require sustained heat above 240°F (115°C) to break down connective tissue into gelatin, which thickens the broth and tenderizes the meat. The Instant Pot’s High Pressure setting achieves this temperature quickly and maintains it throughout cooking. Low Pressure only reaches about 230°F (110°C), which is insufficient for collagen breakdown in a reasonable time.

If you use Low Pressure, you may end up with chewy meat and thin broth even after doubling the cooking time. Stick to High Pressure for any stew with large chunks of beef.

Step-by-Step: Cooking Beef Stew at High Pressure

Cut 2-3 lbs of beef chuck into 1.5-inch cubes. Season with salt, pepper, and flour (optional for thickening).
Use the Sauté function to brown the beef in batches (do not overcrowd). Remove and set aside.
Sauté aromatics (onion, garlic) for 2 minutes, then deglaze with 1 cup beef broth or red wine, scraping up browned bits.
Return beef to the pot. Add vegetables (carrots, potatoes, celery) cut in uniform 1-inch pieces, plus herbs (bay leaf, thyme).
Pour in enough broth to barely cover the ingredients (about 2 cups total liquid). Do not exceed the Max Fill line.
Secure the lid, set valve to Sealing, and select Manual or Pressure Cook on High Pressure for 40 minutes (adjust to 35 for smaller cubes, 45 for larger).
When done, allow Natural Pressure Release for 15 minutes, then turn valve to Venting to release remaining steam.
Open lid, discard bay leaf, adjust seasoning. If stew is too thin, use Sauté to simmer uncovered for 5-10 minutes to reduce.

How Pressure and Time Affect Different Cuts

Beef chuck (shoulder) is ideal for stew: it has high marbling and collagen. At High Pressure, 40 minutes yields tender, shreddable meat. Brisket requires a bit longer (45-50 minutes) due to denser fibers. Round cuts (bottom or top round) can be used but tend to dry out; reduce time to 30-35 minutes and slice against the grain after cooking.

Do not use lean cuts like sirloin or tenderloin; they will become tough and dry under high pressure. For these, Low Pressure for 15-20 minutes might work, but they are better suited for quick searing or roasting.

Natural Release vs. Quick Release: Why It Matters

Natural pressure release (NR) allows the pressure to drop slowly over 10-15 minutes. This lets the meat fibers relax and reabsorb moisture, resulting in juicier, more tender stew. Quick release (QR) vents steam immediately, which can cause the liquid to boil vigorously and spray out, and may shock the meat into toughness.

If you are short on time, a minimum of 10 minutes NR is recommended. For thicker stews with potatoes, always use at least 10 minutes NR to prevent the potatoes from bursting.

Adjusting for Altitude and Thickness

At altitudes above 3,000 feet (915 m), the boiling point of water drops, so High Pressure may not reach the same temperature. Increase cooking time by 5-10% for every 1,000 feet above sea level. For example, at 5,000 feet, cook for 45-50 minutes instead of 40.

If you prefer a thicker stew, you can add a cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons cold water) after pressure cooking and simmer on Sauté for 2-3 minutes. Alternatively, mash some of the potatoes against the side of the pot to naturally thicken the broth.

Pro Tips

Cut beef and vegetables into uniform sizes (1-1.5 inches) for even cooking; larger pieces require longer pressure time.
Always deglaze the pot thoroughly after browning to avoid a Burn warning; use a wooden spoon to loosen all fond.
For extra flavor, add a tablespoon of tomato paste or Worcestershire sauce with the aromatics.
Let the stew rest for 5 minutes after opening the lid to allow flavors to meld before serving.

Common Mistakes to Avoid

Using Low Pressure thinking it will be gentler on the meat – it will actually make it tough and undercooked.
Quick releasing the pressure immediately – this can cause meat to become dry and vegetables to fall apart.
Overfilling the pot with liquid or ingredients – never exceed the Max Fill line to avoid clogging the steam valve.
Skipping the browning step – this loses deep caramelized flavor; at least brown the beef for best results.

FAQ

Can I cook beef stew on Low Pressure in an Instant Pot?

Low Pressure (5-7 psi) is not recommended for beef stew because it will not reach a high enough temperature to break down collagen effectively. You would need to cook for 2-3 times longer, and the meat may still be tough. Stick to High Pressure for best results.

Why does my Instant Pot say ‘Burn’ when cooking beef stew?

The Burn warning usually occurs when there is insufficient liquid or when starchy ingredients (like potatoes or flour) settle at the bottom and scorch. Ensure you have at least 1 cup of thin liquid, deglaze well after browning, and avoid thickening agents before pressure cooking.

How do I adapt a stovetop beef stew recipe for Instant Pot?

Reduce total liquid by about 1/3 since little evaporation occurs. Pressure cook on High for 35-45 minutes instead of simmering for 1.5-2 hours. Use natural release for 10-15 minutes. Add dairy (cream, sour cream) only after pressure cooking to prevent curdling.

The Bottom Line

Cooking beef stew in an Instant Pot is straightforward: always use High Pressure, set the timer for 35-45 minutes depending on meat size, and let the pressure release naturally for at least 10 minutes. This method reliably produces tender, flavorful stew in a fraction of the time compared to stovetop or slow cooker methods. Adjust for altitude and personal preference, and you’ll have a perfect bowl of comfort every time.
