Ingredients Equipment Method Notes

Ingredients
  

  • 3 lbs chuck roast or venison roast
  • 0.5 cup butter 1 stick, sliced
  • 6 whole pepperoncini peppers 6 to 8 peppers
  • 2 tbsp pepperoncini juice from the jar
  • 1 tbsp onion powder
  • 1 tbsp garlic powder
  • 1 tsp dried dill
  • 1 tsp dried parsley
  • 0.5 tsp salt
  • 0.5 tsp black pepper

Equipment

  • Slow cooker (6-quart)
  • Cast Iron Skillet (optional, for searing)
  • Two forks (for shredding)

Method
 

  1. Optional: Heat a cast iron skillet over high heat with a tablespoon of oil. Sear the chuck roast for 2 to 3 minutes per side until deeply browned. This step adds savory depth to the finished dish.
  2. Place the chuck roast in the bottom of the slow cooker. Do not add water or broth.
  3. Sprinkle the onion powder, garlic powder, dried dill, dried parsley, salt, and black pepper evenly over the top of the roast.
  4. Lay the sliced butter on top of the seasoned roast. Scatter the whole pepperoncini peppers around the meat and pour the pepperoncini juice over everything.
  5. Cover and cook on Low for 8 hours. Do not use the High setting — Low heat is essential for the collagen in chuck roast to break down into a fork-tender texture.
  6. Once cooking is complete, use two forks to shred the beef directly in the pot. Stir the shredded meat into the buttery braising juices until fully combined.
  7. Serve warm, garnished with the cooked pepperoncini peppers and a spoonful of the braising liquid over each portion.

Notes

Storage: Refrigerate in an airtight container with braising juices for up to 4 days. Freeze for up to 3 months. Reheat gently on the stovetop or microwave with a splash of liquid to keep moist. Substitutions: Venison roast works with the same cook time. For chicken breasts, reduce cook time to 4 to 5 hours on Low. Add extra pepperoncini or red pepper flakes for more heat. Serving: Pairs well with cauliflower mash, roasted green beans, zucchini noodles, or roasted broccoli for a complete keto dinner.
