Ingredients
Scale
2 lbs beef stew meat or sirloin tips, cut into bite-sized pieces
8 oz mushrooms, sliced
1 large yellow onion, sliced
3 cloves garlic, minced
2 cups beef broth
¼ cup Worcestershire sauce
2 tablespoons soy sauce
2 tablespoons tomato paste
1 teaspoon Dijon mustard
1 teaspoon dried thyme
½ teaspoon dried rosemary
½ teaspoon black pepper
½ teaspoon salt, or to taste
2 tablespoons olive oil
2 tablespoons cornstarch
3 tablespoons cold water
2 tablespoons butter
Instructions
Prepare the beef: Pat the beef tips dry with paper towels. Season with salt and black pepper.
Brown the beef: Heat olive oil in a large skillet over medium-high heat. Sear the beef in batches for 2–3 minutes per side until browned. Transfer to the slow cooker.
Add the vegetables: Arrange the sliced mushrooms, onions, and minced garlic over the beef.
Prepare the gravy: In a bowl, whisk together beef broth, Worcestershire sauce, soy sauce, tomato paste, Dijon mustard, thyme, and rosemary.
Slow cook: Pour the gravy mixture over the beef and vegetables. Cover and cook on LOW for 7–8 hours or HIGH for 4–5 hours, until the beef is fork-tender.
Thicken the gravy: About 20–30 minutes before serving, mix cornstarch with cold water until smooth. Stir the mixture into the slow cooker along with the butter.
Finish cooking: Cover and cook on HIGH for another 15–20 minutes, or until the gravy thickens.
Serve: Stir gently and spoon the beef tips, mushrooms, onions, and gravy over mashed potatoes, steamed rice, or egg noodles.
Notes
Browning the beef before slow cooking adds deeper flavor to the gravy.
Use cremini or baby bella mushrooms for a richer, earthier taste.
For extra richness, stir in ¼ cup heavy cream just before serving.
If the gravy gets too thick, add a little beef broth.
Avoid lifting the slow cooker lid frequently, as this releases heat and increases cooking time.
