Instructions

Season the Steak: Place the sirloin steak pieces into a large bowl. Sprinkle with kosher salt and black pepper, then toss well to ensure all pieces are evenly seasoned.
Brown the Steak: Heat a large skillet over medium-high heat and add vegetable oil. Once the oil is very hot, sear the steak pieces in batches, ensuring they are browned on all sides but not cooked through. Add more oil as needed to prevent sticking. This step enhances flavor with a nice crust.
Combine Ingredients in Slow Cooker: Transfer the seared steak to a 6-quart slow cooker. Add the thinly sliced sweet onion and garlic, gently stirring to combine. Pour in the unsalted beef stock, sprinkle the au jus gravy mix evenly over the top, and lay the thinly sliced butter over everything.
Cook Slowly: Cover the slow cooker and cook on high for 3-4 hours or on low for 6-8 hours. For best results, stir the mixture once every hour if possible to evenly distribute flavors and ensure thorough cooking.
Serve and Enjoy: Once the steak bites are tender and flavorful, serve them hot with your choice of mashed potatoes, egg noodles, or rice for a hearty, satisfying meal.

Notes

This is a great set-it-and-forget-it recipe, perfect for busy days.
Searing the steak before slow cooking boosts flavor and texture.
Use the au jus gravy mix to deepen the savory flavor in the slow cooker.
Stirring occasionally during cooking helps meld flavors and prevents sticking.
Pairs wonderfully with creamy mashed potatoes, buttered egg noodles, or steamed rice.
