Perfect for busy weeknights or cozy gatherings, it delivers deep flavor and melt-in-your-mouth texture in under 90 minutes.

Ingredients

Scale
  • 3–4 lbs beef chuck roast, boneless and well-marbled
  • Salt and pepper, to taste (about 1 teaspoon each)
  • 1 packet (1 oz) ranch seasoning mix
  • 1 packet (1 oz) au jus gravy mix
  • 6–8 whole pepperoncini peppers
  • 2–3 tablespoons pepperoncini liquid (from jar)
  • 4 tablespoons unsalted butter, sliced
  • 1 cup beef broth or stock (low-sodium recommended)
  • 2 tablespoons cornstarch
  • 2 tablespoons cold water
  • Optional: 2-3 cloves fresh garlic, minced
  • Optional: 1 medium onion, sliced

Instructions

  1. Pat the beef chuck roast dry with paper towels. Season all over with salt and pepper.
  2. Select ‘Sauté’ mode on the Instant Pot. Add 1 tablespoon oil and sear the roast for 2-3 minutes per side until browned. (Optional but recommended.)
  3. Turn off ‘Sauté’ mode. Place the roast in the Instant Pot. Sprinkle ranch seasoning and au jus mix evenly over the top.
  4. Scatter pepperoncini peppers around the roast and pour in pepperoncini liquid. Place butter slices over the meat.
  5. Pour beef broth around the edges of the roast.
  6. Seal the lid and set to ‘Manual’ or ‘Pressure Cook’ on high for 60 minutes (for 3 lbs) or 80 minutes (for 4 lbs). Allow a natural pressure release for 15-20 minutes, then quick release any remaining pressure.
  7. Carefully transfer the roast to a cutting board. Shred with two forks or let rest for 10 minutes before slicing.
  8. Select ‘Sauté’ mode again. In a small bowl, whisk together cornstarch and cold water. Stir the slurry into the Instant Pot juices and simmer for 2-3 minutes until thickened, stirring often. Add more broth if needed.
  9. Return shredded beef to the pot, toss with gravy, and serve hot. Garnish with extra peppers or fresh parsley if desired.

Notes

For gluten-free, use gluten-free au jus mix and check ranch ingredients. For dairy-free, substitute butter with olive oil. Searing the roast adds flavor but can be skipped for speed. If the Instant Pot gives a ‘burn’ notice, add more broth and deglaze the pot. Natural pressure release is crucial for tenderness. Leftovers store well and taste even better the next day.
