Ingredients
Scale
Main Ingredients
- 3 pounds sirloin steak, cut into bite-sized pieces
- 2 teaspoons kosher salt
- 1 teaspoon black pepper
- 1 Tablespoon vegetable oil (may need more for browning)
- 1 small sweet onion, thinly sliced
- 3 cloves garlic, thinly sliced
- 1 cup unsalted beef stock
- 1 ounce packet au jus gravy mix
- 4 tablespoons unsalted butter, thinly sliced
Instructions
- Season the Steak: Place the bite-sized sirloin steak pieces into a large bowl, season with kosher salt and black pepper, then toss well to evenly coat the meat with the seasoning.
- Sear the Beef: Heat a large skillet over medium-high heat and add vegetable oil. Once hot, brown the steak pieces in batches, searing them on all sides until they gain a deep brown color. The goal is to develop flavor and color, not to cook the steak through. Add more oil if necessary.
- Combine Ingredients in Slow Cooker: Transfer all of the seared steak pieces to a 6-quart slow cooker. Add the thinly sliced sweet onion and garlic, and gently stir to mix the ingredients together.
- Add Liquids and Butter: Pour the unsalted beef stock evenly over the beef mixture. Sprinkle the au jus gravy mix on top, then lay thin slices of unsalted butter evenly along the surface.
- Slow Cook: Cover the slow cooker and cook on high for 3 to 4 hours, or on low for 6 to 8 hours. Stir the mixture once every hour if possible to ensure even cooking and flavor distribution.
- Serve: Once cooked, serve the garlic butter beef bites hot over mashed potatoes, egg noodles, or rice for a satisfying and hearty meal.
Notes
- You can use vegetable oil or any neutral oil with a high smoke point for searing.
- For a richer flavor, consider using homemade beef stock or broth.
- Stirring every hour helps prevent sticking and mixes flavors evenly but can be skipped if inconvenient.
- The gravy from the au jus mix creates a flavorful sauce; adjust seasoning after cooking if needed.
- Best served fresh but leftovers can be refrigerated up to 3 days or frozen for up to 3 months.
