Method
- Place steak pieces in a large bowl and toss with salt and pepper until evenly coated.
- Heat a large skillet over medium-high heat. Add 1 tablespoon oil and sear half the steak pieces until browned, about 2 to 3 minutes. Don't overcrowd the pan.
- Repeat searing process with remaining 1 tablespoon oil and remaining steak pieces.
- Transfer all seared steak to a 6-quart crockpot.
- Add sliced onion and garlic, tossing gently with the steak.
- Pour beef stock evenly over everything in the crockpot. Sprinkle au jus gravy mix on top.
- Lay butter slices evenly across the top of the steak and vegetables.
- Cover and cook on HIGH for 3 to 4 hours or LOW for 6 to 8 hours, until steak is fork-tender.
- Gently stir before serving and garnish with fresh chopped parsley if desired.
Notes
Searing the steak first locks in flavor and creates depth. Use unsalted stock and butter to control saltiness. Thinly slice garlic to avoid bitterness during long cooking. Stir occasionally for even cooking. Add sliced mushrooms during the last 2 hours for extra flavor.
