Description
This Slow Cooker Smothered Steak is the ultimate comfort food—tender sirloin smothered in savory mushroom gravy with onions and peppers, slow-cooked to perfection. Serve it over mashed potatoes, rice, or noodles for a cozy family dinner.
Ingredients
2 lbs sirloin steak (well-marbled)
1 large onion, sliced
1 green bell pepper, sliced
2 tbsp butter
3 cloves garlic, minced
2 tbsp flour
2 envelopes brown gravy mix, divided
1 ½ cups water
2 tbsp Worcestershire sauce
1 tbsp brown sugar
1 tsp smoked paprika
1 tsp onion powder
1 tbsp steak seasoning
Instructions
Season steak with smoked paprika, onion powder, and steak seasoning.
Heat a skillet over medium-high heat and sear steak on both sides (do not fully cook). Transfer to slow cooker.
In the same skillet, melt butter. Add onions and bell peppers; sauté until softened and browned. Stir in garlic and flour; cook for 1 minute.
Transfer veggie mixture to the slow cooker on top of the steak.
In a bowl, whisk together 1 envelope gravy mix, water, Worcestershire sauce, and brown sugar. Pour over steak and veggies.
Cover and cook on LOW for 6 hours or HIGH for 4 hours until steak is fork-tender.
Remove steak, whisk in second gravy packet, and cook on HIGH for a few minutes to thicken sauce. Return steak to soak in gravy before serving.
Notes
Don’t skip searing the steak—it locks in flavor.
For extra creaminess, stir in a splash of heavy cream at the end.
Delicious served over mashed potatoes, rice, or buttered egg noodles.
Leftovers keep in the fridge for up to 3 days or freeze for 2 months.
