How to Make Slow Cooker Steakhouse Burgers

Step 1: Prepare the Slow Cooker

Lightly coat the inside of your slow cooker with nonstick cooking spray for easy cleanup.

Spread the sliced onions evenly across the bottom of the slow cooker.

Step 2: Add the Burgers

Place the frozen burger patties on top of the onions in a single layer whenever possible. Slight overlapping is fine if needed.

Step 3: Add Mushrooms

Scatter the sliced mushrooms around and over the burger patties.

Step 4: Pour on the Steak Sauce

Pour the steak sauce evenly over the burgers, onions, and mushrooms, ensuring every patty gets coated.

Step 5: Slow Cook

Cover and cook:

  • Low: 5–6 hours

  • High: 3–3½ hours

Cook until the burgers reach an internal temperature of 160°F (71°C).

Step 6: Serve

Carefully remove the burgers using a spatula.

Stir the onions and mushrooms into the remaining sauce.

Place each burger on a toasted bun and top generously with the saucy onion-mushroom mixture.

Add your favorite toppings and serve immediately.
