Ingredients

Gather these for a 4-6 serving pot roast:

• 2 teaspoons salt
• 1 teaspoon black pepper
• 2 tablespoons olive oil
• 1 large onion, sliced
• 4 cloves garlic, minced
• 1 cup beef broth
• 2 tablespoons Worcestershire sauce
• 1 tablespoon tomato paste

Equipment Needed

You need an Instant Pot (6-quart or 8-quart). Other tools include:

• Tongs
• Wooden spoon
• Measuring cups and spoons
• Cutting board and knife
• Small bowl for slurry

Keep everything handy. Prep saves time.

Step-by-Step Instructions

Follow these steps for success.

1. Step 1: Prepare the Meat
   Pat the chuck roast dry with paper towels. Season all sides with salt and pepper. Let it sit for 10 minutes. This draws out moisture for better searing.
2. Step 2: Sear the Roast
   Set your Instant Pot to Sauté mode. Add olive oil. Wait for it to shimmer. Sear the roast for 4-5 minutes per side until browned. Remove to a plate. Work in batches if needed. Browning builds flavor through Maillard reaction.
3. Step 3: Sauté Aromatics
   Keep Sauté mode on. Add sliced onion. Cook for 3-4 minutes until softened. Stir in minced garlic. Cook 1 minute more. Scrape up browned bits from the pot bottom. These add depth.
4. Step 4: Deglaze and Add Liquids
   Stir in tomato paste. Cook 1 minute. Pour in beef broth and Worcestershire sauce. Use a wooden spoon to dissolve bits. Turn off Sauté.
5. Step 5: Assemble the Pot
   Return roast to the pot. Add thyme, rosemary, bay leaves, carrots, and potatoes around it. Do not submerge veggies fully. They cook perfectly on top. Secure the lid. Set valve to Sealing.
6. Step 6: Pressure Cook
   Select Manual or Pressure Cook on High. Set timer for 60 minutes. Natural release for 20 minutes. Quick release remaining pressure. Open carefully.
7. Step 7: Make Gravy
   Remove roast and veggies to a platter. Tent with foil. Switch to Sauté. Mix cornstarch and water into a slurry. Stir into pot juices. Simmer 2-3 minutes until thickened. Taste and adjust salt.
8. Step 8: Serve
   Slice roast against the grain. Spoon gravy over meat and veggies. Pair with crusty bread or green salad.

Total time: About 1 hour 45 minutes. Hands-on: 20 minutes.

Tips for Perfect Pot Roast

Achieve restaurant results with these pro tips.

• Cut vegetables uniformly. This ensures even cooking. Smaller pieces turn mushy.
• Do not skip searing. It locks in juices and boosts flavor.
• Use low-sodium broth. Control salt levels.
• For thicker gravy, add more slurry. Simmer longer if needed.
• Fresh herbs elevate taste. Swap dried for 1 tablespoon each fresh thyme and rosemary.
• Room temperature meat sears better. Let it sit out 30 minutes.
• Avoid overcrowding. Use a larger Instant Pot for bigger roasts.
• Natural release keeps meat tender. Quick release can toughen it.
• Deglaze thoroughly. Burnt bits trigger burn notice.
• Store leftovers in airtight containers. Refrigerate up to 4 days. Freeze for 3 months.
• Reheat on Sauté with extra broth.

Common Mistakes to Avoid

New cooks often err here. Learn from them.

• Overfilling the pot. Fill max 2/3 full for pressure buildup.
• Skipping fat trim. Excess leads to greasy gravy.
• Forgetting bay leaves. They impart subtle aroma.
• Rushing release. Patience yields fall-apart meat.
• Stirring veggies under meat. They steam instead of roast.
• Using lean cuts. Sirloin dries out.
• Ignoring burn notice. Add more liquid next time.

These fixes make cooking foolproof.

Variations

Customize your pot roast.

• Classic Root Veggies: Add parsnips or celery.
• Mexican-Style: Use beef bouillon, cumin, chili powder, and cilantro. Top with lime.
• Asian Twist: Soy sauce, ginger, hoisin. Serve over rice.
• Mushroom Lover: Sauté 8 ounces mushrooms with onions.
• Gluten-Free: Cornstarch is fine. Skip Worcestershire or use tamari.
• Slow Cooker Conversion: Cook 8 hours low after searing.

These keep meals exciting.
