Method
- Pat beef dry, season with salt and pepper, and sear in olive oil in a skillet over medium-high heat for 2-3 minutes per side. Transfer to slow cooker.
- Sauté onions in the skillet for 3-4 minutes, add garlic and mushrooms for 2 minutes, then transfer to slow cooker.
- Whisk onion soup mix, cream of mushroom soup, beef broth, Worcestershire sauce, and soy sauce. Pour over beef and vegetables.
- Cover and cook on low for 6-8 hours or high for 3-4 hours until beef is fork-tender.
- Mix cornstarch with cold water to make a slurry, stir into slow cooker in the last 30 minutes to thicken gravy.
- Taste and adjust seasoning. Garnish with thyme before serving.
Notes
Sear beef for better flavor. Keep slow cooker 2/3 full to avoid overcrowding. Use cornstarch slurry for perfect gravy thickness. Store refrigerated for up to 4 days or frozen for up to 3 months, reheating with broth to restore consistency.
