Ingredients
Scale
- 3–4 pounds beef chuck roast
- 1 packet (about 1 oz / 28 g) ranch seasoning mix
- 1 packet (about 0.87 oz / 24 g) au jus gravy mix
- 1/2 cup (1 stick / 113 g) unsalted butter, sliced
- 7–8 pepperoncini peppers with juice (about 1/2 cup / 120 ml)
- Salt and pepper to taste
Instructions
- Pat the chuck roast dry with paper towels. Sprinkle salt and pepper evenly on all sides.
- Optional: Heat a tablespoon of oil in a skillet over medium-high heat. Brown the roast on all sides, about 3-4 minutes per side.
- Place the roast at the bottom of the slow cooker. Sprinkle ranch seasoning mix and au jus gravy mix evenly over the top.
- Lay sliced butter over the roast. Pour the jar of pepperoncini peppers along with their juice around and over the roast.
- Cover and cook on low for 8 hours or on high for 4-5 hours until the roast is fork-tender and easily pulls apart.
- If the sauce is too thin, remove the roast and turn the slow cooker to high. Mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir into the sauce. Cook uncovered for 15 minutes until thickened.
Notes
Searing the roast is optional but adds extra flavor. Use the pepperoncini juice for signature tang. For a thicker sauce, use cornstarch slurry at the end. Butter keeps the roast juicy; substitute with olive oil or plant-based butter for dairy-free. Leftover sauce is great for sandwiches or mashed potatoes. Slow and low cooking yields best tenderness.
