Recipe Details
- Prep Time: 10 minutes
- Cook Time: 6 hours (Low) or 4 hours (High)
- Yield: 6 servings
🛒 Ingredients
- 2 lbs beef stew meat, sirloin tips, or chuck roast (cut into 1.5-inch cubes)
- 8 oz fresh white button or cremini mushrooms, sliced
- 1 large yellow onion, cut into thin wedges or sliced
- 2 cloves garlic, minced
- 2 cups low-sodium beef broth
- 2 tbsp Worcestershire sauce
- 1 packet (1 oz) dry onion soup mix
- 1/2 tsp dried thyme
- 1/2 tsp coarsely cracked black pepper
- Salt (to taste)
- 3 tbsp cornstarch dissolved in 3 tbsp cold water (for thickening slurry)
- Fresh chopped parsley (for garnish)
👩🍳 Step-by-Step Instructions
- Sear the Beef (Optional for deeper flavor): Pat the cubed beef completely dry with a paper towel and season lightly with black pepper. If you have time, sear the meat in a hot skillet with a tablespoon of oil for 1–2 minutes per side until a golden brown crust forms. If you’re in a rush, you can skip this step and place the beef directly into the slow cooker raw. [1]
- Layer the Crockpot: Place your seasoned beef chunks into an even layer at the bottom of the slow cooker. Scatter the fresh sliced mushrooms, sliced onions, and minced garlic evenly over the top of the meat. [1, 2]
- Mix and Pour Liquids: In a separate measuring cup or small bowl, whisk together the beef broth, Worcestershire sauce, dry onion soup mix, dried thyme, and black pepper until fully combined. Pour the liquid mixture directly over the beef and vegetables in the pot. [1, 2]
- Slow Cook: Secure the lid tightly onto your cooker. Cook on Low for 6 to 8 hours or on High for 4 hours until the beef tips are completely fork-tender and break apart easily. [1]
- Thicken the Gravy: About 20 to 30 minutes before serving, whisk the cornstarch and cold water together in a small cup to create a smooth slurry. Stir this slurry directly into the hot, bubbling liquids in the slow cooker. Cover and let it cook on High for an additional 15 minutes until the gravy thickens into a rich, velvety consistency. [1, 2]
- Garnish and Serve: Give everything a gentle final stir. Garnish generously with fresh chopped parsley and serve hot over a mountain of creamy mashed potatoes, buttered egg noodles, or fluffy white rice! [1]
💡 Chef’s Pro Tips
- Choosing the Best Meat: Beef chuck roast cut into cubes yields the most tender results for longer cook times because its healthy marble of fat breaks down beautifully during the slow braise. [1]
- Watch the Salt: Dry onion soup mixes and store-bought beef broths can carry a lot of sodium. Always use low-sodium broth and wait to add any extra salt until the very end after tasting the finished gravy. [1]
