Ingredients

Units Scale

Steak and Seasonings

  • 3 pounds sirloin steak, cut into bite-sized pieces
  • 2 teaspoons kosher salt
  • 1 teaspoon black pepper
  • 1 Tablespoon vegetable oil (you may need more)

Vegetables and Aromatics

  • 1 small sweet onion, thinly sliced
  • 3 cloves garlic, thinly sliced

Liquids and Seasoning Mix

  • 1 cup unsalted beef stock
  • 1 ounce packet au jus gravy mix
  • 4 tablespoons unsalted butter, thinly sliced

Instructions

  1. Season the steak: Place the 3 pounds of sirloin steak cut into bite-sized pieces into a large bowl. Add 2 teaspoons kosher salt and 1 teaspoon black pepper, then toss to coat the meat evenly with the seasonings.
  2. Sear the steak: Heat a large skillet over medium-high heat and add 1 tablespoon of vegetable oil. Once the oil is hot, sear the steak pieces in batches, ensuring they develop a brown crust on all sides without cooking fully through. Add more oil if necessary to keep the pan hot.
  3. Prepare the slow cooker: Transfer all the seared steak pieces into a 6-quart slow cooker. Add the thinly sliced sweet onion and garlic, gently stirring to combine the ingredients.
  4. Add liquids and butter: Pour 1 cup of unsalted beef stock into the slow cooker. Sprinkle the 1-ounce packet of au jus gravy mix evenly over the top. Lay the 4 tablespoons of thinly sliced unsalted butter over the steak and aromatics.
  5. Slow cook the steak bites: Cover the slow cooker and cook on high for 3 to 4 hours, or on low for 6 to 8 hours. Stir the mixture gently once every hour if possible to ensure even cooking and flavor distribution.
  6. Serve: Once cooked tender, serve the garlic butter steak bites hot alongside mashed potatoes, egg noodles, or rice for a complete meal.

Notes

  • Ensure the skillet is very hot before searing to get a good crust on the steak bites without overcooking.
  • Stirring occasionally during slow cooking helps prevent the meat from sticking and promotes even flavor infusion.
  • You can adjust butter quantity to your preference for richer flavor.
  • Use a 6-quart slow cooker for optimal cooking space and heat distribution.
  • Leftovers store well in the refrigerator for up to 3 days and can be reheated gently on the stovetop or microwave.
