Ingredients
Method
- Season beef with salt and pepper in a large bowl. Toss to coat evenly.
- Heat oil in a skillet over medium-high heat. Sear beef in small batches until browned on all sides. Do not overcrowd the pan.
- Transfer seared beef into a 6-quart slow cooker. Add onion and garlic.
- Pour beef stock over the beef. Sprinkle au jus mix evenly. Top with butter slices.
- Cover and cook on low for 6–8 hours or high for 3–4 hours. Stir once or twice during cooking if possible.
- Garnish with fresh parsley or thyme before serving.
Notes
- Flat iron steak is a flavorful, cost-effective option if sirloin is not available.
- Add mushrooms, fresh herbs, or a splash of red wine for richer depth.
- For thicker gravy, whisk together 1 tablespoon cornstarch with 2 tablespoons water and stir in 30 minutes before serving.
- Leftovers reheat well on the stovetop or in the microwave.
