Ingredients
For the Pot Roast:
- 4 1/2 lbs boneless beef bottom round roast
- 2 cups (1/2 lb) peeled and thick-sliced carrots or baby carrots
- 1 lb fresh mushrooms, thickly sliced
- 1 large onion, finely diced
- 6 cloves garlic (about 1/2 head), pressed
- 1/3 cup all-purpose flour
- 1 oz onion soup or dip mix
- 1/2 tbsp Mrs. Dash (salt-free seasoning)
- 2 cups reduced-sodium vegetable or beef broth
- 1/2 cup red wine
- 1 cup heavy whipping cream
- 2 tsp salt (to taste)
Instructions
- Prepare the Slow Cooker: Line the bottom of the slow cooker with the thickly sliced carrots.
- Sear the Beef: Heat a large, heavy-bottomed skillet over high heat. Add 4 tbsp cooking oil (I recommend extra light olive oil for its high smoke point). Once the skillet is very hot, sear all sides of the beef roast (2-3 minutes per side) until well-browned. Be cautious of splatters, and wear an apron! Transfer the seared roast to the slow cooker.
- Sauté Mushrooms and Onions: In the same skillet, sauté the sliced mushrooms and diced onions over medium-high heat for about 5-7 minutes until softened. Add the pressed garlic and cook for an additional minute, then remove from heat.
- Make the Gravy: In a medium saucepan, whisk together the broth, heavy cream, onion soup mix, Mrs. Dash seasoning, salt, and flour. Heat over medium-high heat, whisking until the mixture thickens to a gravy-like consistency.
- Combine the Mixture: Stir the sautéed mushrooms and onions into the gravy. Add the red wine, stir well, and bring to a simmer.
- Slow Cook: Pour the mushroom gravy over the beef roast in the slow cooker. Cover and cook on high for 6 hours, or until the beef is tender and easily shreds.
- Shred the Beef: Just before serving, transfer the beef to a serving dish. Use forks to shred the meat and pour the gravy over it while it’s hot to absorb the flavorful sauce. Taste and adjust seasoning with more salt if desired.
