Ingredients
– 3 pounds round steak or sirloin steak
– 1/2 to 1 large sweet onion
– 2 to 4 teaspoons minced garlic
– 1 to 2 teaspoons kosher salt
– 1 teaspoon black pepper
– 4 tablespoons unsalted butter
– 1 cup unsalted beef broth or beef stock
– 1-ounce packet au jus gravy mix
– 1 tablespoon cornstarch
– 2 tablespoons Worcestershire sauce
– 2 tablespoons olive or vegetable oil
– 1/4 cup cream of mushroom soup
– fresh herbs (parsley, rosemary, thyme)
– red pepper flakes
– red wine
Instructions
First Step: Prepare the Steak and Ingredients
Trim and cut 3 pounds of sirloin or round steak into 1-inch bite-sized pieces ensuring even cooking. Dice or thinly slice 1 large sweet onion and mince 3 garlic cloves to boost the aromatic base.
Second Step: Season the Steak Bites
Season the steak cubes evenly with 1 to 2 teaspoons kosher salt and 1 teaspoon black pepper. Toss gently to coat all pieces. If you prefer extra depth, you may sear the steak in olive oil over medium-high heat in batches until browned on all sides (about 2-4 minutes per batch), but this step is optional.
Third Step: Layer Ingredients in the Crockpot
Place diced onions at the bottom of the crockpot to create a flavor foundation. Arrange seasoned or seared steak bites evenly on top. Add the minced garlic scattered over the meat for maximum infusion.
Fourth Step: Add Liquids and Butter
Pour 1 cup of unsalted beef broth evenly over the steak and onions. For enhanced flavor, sprinkle the au jus gravy mix or add 2 tablespoons Worcestershire sauce now, if using. Distribute 4 tablespoons of sliced unsalted butter on top.
Fifth Step: Cook and Stir
Cover the crockpot and cook on low for 6-8 hours or high for 3-4 hours until steak bites are tender and flavorful. Stir gently once or twice if possible to blend flavors and melt butter thoroughly.
Final Step: Thicken Sauce and Serve
If a thicker gravy is desired, mix 1 tablespoon cornstarch with ½ cup water and stir into the crockpot during the final 15-30 minutes of cooking, increasing heat to thicken. Serve immediately with mashed potatoes, rice, vegetables, or crusty rolls. Garnish with fresh parsley for color.
