Ingredients You’ll Need

• 1 tablespoon olive oil – For searing.
• 1 small onion, chopped – Flavor base.
• 3 cloves garlic, minced – Non-negotiable.
• 1 cup beef broth – Cooking liquid magic.
• 2 tablespoons Worcestershire sauce – Depth boost.
• 1 tablespoon tomato paste – Adds richness.
• 4 carrots, cut into chunks – Sweet balance.

Step-by-Step Instructions

1. Sear the roast.
Turn on sauté mode. Add olive oil and sear the chuck roast on all sides until nicely browned. Browning builds serious flavor. Don’t skip it.

2. Add aromatics.
Remove roast briefly. Add onion and garlic to the pot. Cook for 2–3 minutes until fragrant. Scrape the bottom to lift those browned bits.

3. Add liquid and seasoning.
Pour in beef broth, Worcestershire sauce, and tomato paste. Stir well. Add thyme, salt, and pepper.

4. Pressure cook.
Place roast back into the pot. Seal lid and cook on high pressure for 60 minutes. Let it naturally release for 15 minutes before quick releasing.

5. Add vegetables.
Remove roast temporarily. Add carrots and potatoes to the broth. Return roast on top. Cook on high pressure for 5 minutes. Quick release immediately.

6. Thicken gravy.
Remove roast and veggies. Turn on sauté mode. Stir in cornstarch slurry if desired. Cook until gravy thickens.

7. Slice and serve.
Slice or shred roast. Spoon gravy generously over everything. Serve hot.
