Ingredients You’ll Need

• 3–4 pounds chuck roast – The star of the show.
• 1 tablespoon olive oil – For searing.
• 1 packet ranch seasoning mix – Flavor bomb.
• 1 packet au jus gravy mix – Savory depth.
• ½ cup beef broth – Helps pressure build.

Step-by-Step Instructions

1. Sear the roast.
Turn on sauté mode. Heat olive oil and sear roast on both sides until browned. Remove and set aside.

2. Deglaze the pot.
Pour in beef broth and scrape up browned bits. This prevents burn notice.

3. Add the roast back.
Place roast into the pot. Sprinkle ranch and au jus seasoning evenly over the top.

4. Add peppers and butter.
Place pepperoncini around the roast. Pour in a little juice and add butter on top.

5. Pressure cook.
Seal lid and cook on high pressure for 60 minutes. Let natural release for 15 minutes, then quick release.

6. Shred and serve.
Shred beef with two forks and stir into the juices before serving.

Common Mistakes to Avoid
