Ingredients:

- ¼ cup low-sodium beef broth
- 2 Tbsp olive oil
- 1 packet (1 oz or 3 Tbsp) ranch dressing mix *see notes for GF
- 4 Tbsp unsalted butter, sliced

- 1 packet au jus mix (or substitute with brown gravy mix *see notes for GF)
- 2 garlic cloves, minced
Instructions:
- Prepare the Beef: Season the chuck roast with black pepper on both sides.
- Sear the Roast: Heat 2 Tbsp olive oil in a large skillet over medium-high heat. Sear the beef for 2-3 minutes per side until browned.
- Assemble in Slow Cooker: Pour the beef broth into the slow cooker. Place the seared beef on top, then sprinkle with ranch dressing mix and au jus mix. Add minced garlic, pepperoncini, and distribute butter slices over the roast.
- Cook: Cover and cook on low for 7-9 hours or on high for 4-6 hours, until the meat is fork-tender. Cooking time may vary depending on the thickness of the cut.
- Shred and Serve: Shred the beef using two forks and mix it into the buttery gravy in the slow cooker. Serve hot.
Tips
- For extra flavor, deglaze the skillet with a splash of beef broth after searing and pour it into the slow cooker.
- Don’t skip the sear—this adds depth to the final dish.
- For a thicker gravy, mix a tablespoon of cornstarch with water and stir it in during the last 30 minutes of cooking.
Variations and Substitutions
- No slow cooker? Use an oven-safe Dutch oven at 275°F for 3-4 hours or until tender.
- Gluten-free? Substitute au jus mix with a GF brown gravy mix and ensure your ranch dressing mix is gluten-free.
- Spicier version? Add more pepperoncini and a dash of red pepper flakes.
- Low-sodium option? Use reduced-sodium beef broth and seasoning mixes.
