Ingredients
Scale
Spice Rub
- 2 tablespoons all purpose flour (or gluten-free flour mix)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
Main Ingredients
- 2.5 lb boneless beef chuck roast (trimmed)
- ½ tablespoon olive oil
- 4 cups onion (thinly sliced half moons, about 3 small or 2 medium onions)
- ⅓ cup sherry wine
- 2 cups beef bone broth
- 1 1¼-ounce package dry onion soup mix (about 3 tablespoons; check labels for gluten-free or use homemade recipe)
- 4 sprigs fresh thyme
Instructions
- Prepare Spice Rub: In a small bowl, combine the flour, garlic powder, onion powder, kosher salt, and black pepper. Rub 1 tablespoon of this mixture evenly over the chuck roast. Set both the roast and the remaining spice mixture aside.
- Caramelize Onions: Place ½ tablespoon olive oil and the sliced onions in a large pan starting with a cold pan. Cook over medium-low heat, stirring often to prevent burning, until the onions turn golden brown and caramelized, about 25 to 30 minutes. The onions should develop a sweet, rich flavor.
- Thicken Onion Base: Stir the remaining spice mixture into the caramelized onions thoroughly. Pour in the sherry wine and cook for 1 to 2 minutes until the mixture thickens and the alcohol begins to cook off, leaving a fragrant aroma.
- Add Broth and Seasoning: Add the beef bone broth and dry onion soup mix to the onion mixture, stirring to combine. Transfer this onion broth base into the slow cooker.
- Brown the Roast: Wipe out the pan used for onions (ensure it’s dry), spray it lightly with olive oil, and heat over medium-high. Sear the seasoned chuck roast on each side for about 2 to 3 minutes until caramelized and browned.
- Slow Cook: Place the browned roast on top of the onion mixture in the slow cooker. Add the thyme sprigs around the roast. Cover and cook on the low setting for 8 hours.
- Slice and Finish Cooking: After 7 hours, remove the roast and slice it into 6 pieces. Taste the broth and adjust salt if needed. Return the sliced beef to the slow cooker and continue cooking uncovered for 1 more hour until the meat is fork tender.
- Serve: Serve the pot roast and onions over egg noodles, mashed potatoes, mashed cauliflower, or roasted potatoes and vegetables for a complete comforting meal.
- Alternative Stove/Oven Method: After browning the roast and caramelizing the onions, transfer both to a Dutch oven or heavy oven-safe pot. Bake in a preheated 375°F oven for 2½ hours or until fork tender. Check liquid levels after 1½ hours and add more beef broth if necessary. Cook until meat and vegetables are tender.
Notes
- For gluten-free, use a gluten-free flour mix and verify that the onion soup mix is gluten-free or make your own from scratch.
- Sherry wine adds depth to the sauce but can be substituted with dry white wine or extra beef broth if preferred.
- The long, low cooking time in the slow cooker is essential for tenderizing the chuck roast.
- This recipe pairs wonderfully with creamy mashed potatoes, egg noodles, or roasted root vegetables.
- Leftovers store well and taste great reheated the next day as flavors meld even further.
