A cozy, easy slow cooker recipe featuring a tender chuck roast cooked low and slow with ranch seasoning, pepperoncini peppers, and a buttery sauce for a flavorful comfort meal.

Ingredients

Scale
  • 34 pounds chuck roast
  • 1 packet (about 1 ounce) ranch seasoning mix
  • 1 packet (about 1 ounce) au jus gravy mix
  • 1/2 cup (1 stick or 115 grams) unsalted butter
  • 68 pepperoncini peppers with juice
  • 1 cup (240 ml) beef broth
  • Freshly ground black pepper to taste
  • Optional: 1 teaspoon garlic powder

Instructions

  1. Trim excess fat from the chuck roast, leaving a bit for flavor (about 5 minutes).
  2. Optional: Heat 1 tablespoon oil in a cast iron skillet over medium-high heat and sear the roast on all sides until browned, about 3 minutes per side.
  3. Place the trimmed (and optionally seared) roast in a 6-quart slow cooker.
  4. Sprinkle ranch seasoning mix and au jus gravy mix evenly over the roast. Add garlic powder if using.
  5. Place the butter on top of the roast. Scatter pepperoncini peppers around and on top, pouring in some of their juice.
  6. Pour beef broth around the roast, avoiding pouring directly on top to keep seasoning in place. Season with freshly ground black pepper to taste.
  7. Cover and cook on low for 6-8 hours until the meat is fork-tender and easily shredded.
  8. After 6 hours, check doneness by piercing with a fork. If it does not pull apart easily, cook for another 1-2 hours.
  9. Remove the roast with tongs and shred it with two forks in the slow cooker or on a plate. Mix shredded beef with the sauce to soak up flavor.
  10. Optional: If sauce is too thin, mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the slow cooker 15 minutes before serving to thicken.

Notes

Searing the roast before slow cooking is optional but adds extra flavor. Avoid lifting the lid during cooking to maintain heat. Use fresh pepperoncini peppers with juice for best flavor. To thicken sauce, use a cornstarch slurry 15 minutes before serving. Can be adapted for Instant Pot cooking (60-70 minutes on high pressure).
