Ingredients for Slow Cooker Steak Bites

3 pounds sirloin steak, cut into bite-sized pieces
2 teaspoons kosher salt
1 teaspoon black pepper
2 tablespoons vegetable oil
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
Fresh chopped parsley for garnish (optional)

Preparing Your Slow Cooker Steak Bites

Tossing the Steak with Salt and Pepper

In a large bowl, combine the sirloin steak pieces with kosher salt and black pepper, ensuring each bite is well-seasoned. This step is crucial as it sets the foundation for the flavor right from the start.

Searing the Steak Bites

Heat a large skillet over medium-high heat and add half of the vegetable oil. As the oil heats up, sear the steak bites in batches—brown all sides until you see a delicious crust form. This step adds depth to the flavor. Once done, transfer the seared steak to your 8-quart slow cooker.

Cooking the Aromatics

Now it’s time to add some fantastic flavor. Toss the sliced onion and garlic into the slow cooker with the seared steak bites. Gently combine the ingredients so that each bite benefits from that onion and garlic goodness.

Adding Liquid and Flavor

Pour the unsalted beef stock over the steak and sprinkle the au jus gravy mix across the top. This mix adds a savory richness that’s hard to beat. For extra richness, lay thin slices of unsalted butter over the mixture. It’ll melt down to add even more flavor.

Slow Cooking for Perfect Tenderness

Cover the slow cooker and set it on high for 3-4 hours or low for 6-8 hours. Be sure to stir occasionally if you can. The longer cook time will yield more tender steak bites, perfect for those who like their beef melt-in-your-mouth soft.

Garnishing Your Dish

Once the cooking time is up, serve the steak bites hot. If you want, garnish with fresh chopped parsley for a pop of color and freshness.

Serving Suggestions

These Slow Cooker Steak Bites are delicious served with crusty bread, over mashed potatoes, or alongside a fresh garden salad. They also pair perfectly with a glass of red wine for a more indulgent experience. No matter how you serve them, they’re sure to satisfy.

Tips for Success

For enhanced flavor, consider marinating the steak bites for a few hours before cooking. A simple marinade of soy sauce and garlic can elevate the taste further.
Ensure to sear the steak in batches; overcrowding the pan can lead to steaming rather than browning, which you don’t want.
If you’re short on time, use pre-sliced beef for quicker preparation—it’ll make your cooking experience more efficient.

Variations

Spicy Kick: If you like some heat, add a teaspoon of cayenne pepper or red pepper flakes for spice.
Vegetable Additions: Toss in some diced bell peppers or mushrooms for a heartier dish full of textures.
Gluten-Free Option: Swap out the au jus mix for a gluten-free version to meet dietary needs without sacrificing flavor.
