Ingredients

Scale
  • 3 to 4 pounds chuck roast (well-marbled)
  • 1 packet (about 1 ounce) ranch seasoning mix
  • 1 packet (about 1 ounce) au jus gravy mix
  • 1/2 cup (113 grams) unsalted butter, softened
  • 1 jar (about 7 ounces) pepperoncini peppers with juice
  • 1 teaspoon garlic powder
  • Black pepper to taste
  • Salt (optional, depending on seasoning mixes)
  • Optional: fresh herbs like thyme or rosemary
  • Optional: red potatoes or carrots for one-pot meal

Instructions

  1. Pat your 3 to 4-pound chuck roast dry with paper towels. Season lightly with salt and black pepper on both sides if desired.
  2. In a small bowl, combine ranch seasoning mix and au jus gravy mix with 1/2 cup softened unsalted butter. Blend until smooth and creamy.
  3. Spread the ranch-au jus butter mixture evenly over the entire surface of the roast.
  4. Place the roast in the slow cooker. Pour the entire jar of pepperoncini peppers with juice over and around the roast.
  5. Cover and cook on low for 7 to 8 hours or on high for 4 to 5 hours until the meat is fork-tender.
  6. Remove the roast carefully and place on a serving platter. Stir the cooking juices and pepperoncini butter gravy in the slow cooker.
  7. If thicker gravy is desired, whisk in a slurry of 1 tablespoon cornstarch mixed with 2 tablespoons cold water and cook on high for 10 minutes.
  8. Spoon the pepperoncini butter gravy over thick slices of pot roast and serve.

Notes

Searing the roast before slow cooking adds extra flavor but is optional. Use a well-marbled chuck roast for best tenderness. Do not overcrowd the slow cooker if adding vegetables. Let the roast rest 10 minutes before slicing to keep it moist. For thicker gravy, use cornstarch slurry. Butter is key for the gravy; for dairy-free, substitute with vegan butter.
