Description

Slow Cooker Pepperoncini Beef Roast with Rosemary is a tender, flavor‑packed dish where a chuck roast slowly simmers with tangy pepperoncini, garlic, and rosemary until it melts in your mouth. It’s an easy dump‑and‑go meal that yields rich, savory, juicy beef — perfect over mashed potatoes, in sandwiches, or with roasted vegetables.


Ingredients

  • 34 lb boneless chuck roast
  • 68 whole pepperoncini peppers (from a jar)
  • ¼½ cup pepperoncini juice (from the jar)
  • 4 cloves garlic, minced
  • 1 large onion, sliced
  • 23 sprigs fresh rosemary
  • ½ cup beef broth (optional, for extra sauce)
  • Salt and black pepper, to taste
  • 12 tbsp olive oil (optional, for searing)

Instructions

  1. Season the chuck roast generously with salt and pepper on all sides.
  2. (Optional) Heat olive oil in a skillet over medium‑high heat. Sear the roast on all sides until browned, then transfer to the slow cooker.
  3. Place the sliced onion and minced garlic at the bottom of the slow cooker. Set the roast on top.
  4. Add pepperoncini peppers and pour in pepperoncini juice. Tuck rosemary sprigs around the beef, and add beef broth if you want more sauce.
  5. Cover and cook on low for 8–9 hours (or high for 4–5 hours), until the beef is fall-apart tender.
  6. Remove the roast, shred the meat with two forks, then return the shredded beef to the cooking juices so it can soak up flavor.
  7. Serve hot — over mashed potatoes, on rolls, with veggies, or as desired.

Notes

  • Add baby potatoes and carrots in the last 2–3 hours for a full one‑pot meal.
  • Swap rosemary for thyme, or add a splash of red wine for deeper flavor.
  • For richer sauce, stir in a small knob of butter at the end.
  • Use brisket or rump roast if chuck isn’t available — adjust cooking time as needed.
  • For a crispier exterior, broil shredded beef on a baking sheet for a few minutes before serving.
