Slow Cooker Garlic Butter Steak Bites feature deeply seared sirloin finished low and slow in a savory au jus–based sauce, then brought together with butter and fresh garlic at the end. Big, beefy flavor with minimal hands-on time, this is a comforting, crowd-pleasing meal that pairs perfectly with mashed potatoes or egg noodles.

Ingredients

Units Scale
  • 2 pounds top sirloin steak, cut into bite-sized pieces
  • 1 teaspoon Kosher salt, or to taste
  • 1 teaspoon Freshly ground black pepper, or to taste
  • 2 tablespoons olive oil, for searing
  • 1 large white onion, thinly sliced (about 1/4-inch thick)
  • 4 cloves garlic, crushed then minced, divided
  • 1 (1-ounce) packet McCormick Au Jus Gravy Mix
  • 1 cup beef stock or beef broth
  • 2 tablespoons Worcestershire sauce
  • 6 tablespoons unsalted butter, cut into small pats

Instructions

  1. Cut the top sirloin into bite-sized pieces and season generously with kosher salt and freshly ground black pepper. Crush the garlic, then mince it and divide it equally. Thinly slice the white onion into ¼-inch slices and set aside.
  2. Heat olive oil in a cast-iron skillet over medium-high heat. Working in batches, sear the steak bites until well browned on all sides. Transfer the seared steak to the slow cooker as it finishes.
  3. Spread the sliced onions evenly across the bottom of the slow cooker. Arrange the seared steak bites on top of the onions.
  4. In the same skillet, pour in the beef stock, au jus gravy mix, half of the minced garlic, and Worcestershire sauce. Stir to combine, scraping up any browned bits from the pan. Simmer for 3–4 minutes, until the au jus is fully dissolved and the sauce is smooth.
  5. Pour the sauce over the steak and onions. Cover and cook on low for 4–5 hours, or until the steak is tender.
  6. Scatter the remaining garlic over the steak bites, then arrange the butter evenly on top. Cover and cook for an additional 10 minutes, until the butter is melted. Stir gently to combine (see note below).
  7. Serve hot over mashed potatoes or egg noodles.

Notes

  1. For a sharper garlic bite, a small pinch of the minced garlic can be reserved and sprinkled over the finished dish just before serving.
