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 olive oil
• 1 small sweet onion, thinly sliced
• 3 cloves garlic, thinly sliced
• 1 cup unsalted beef stock or broth
• 1 packet (1 ounce) au jus gravy mix
• 4 tablespoons unsalted butter, thinly sliced
• Fresh chopped parsley (optional, for garnish)

Optional substitutions: Round steak, stew meat, or chuck roast can be used instead of sirloin.

Equipment Needed

• 6-quart slow cooker
• Large skillet for searing (optional but recommended)
• Sharp knife and cutting board

Step-by-Step Instructions

1. Season the steak – Place steak pieces in a large bowl and toss with salt and black pepper until evenly coated.
2. Sear the beef – Heat a skillet over medium-high heat and add half of the olive oil. Sear steak pieces in batches until browned on all sides. Transfer the seared steak to the slow cooker. Add more oil if needed for remaining batches.
3. Add aromatics – Place sliced onion and garlic over the steak bites in the slow cooker and toss gently to combine.
4. Add liquids and butter – Pour in the beef stock and sprinkle the au jus gravy mix evenly over the top. Lay slices of butter across the surface.
5. Cook – Cover and cook on HIGH for 3–4 hours or LOW for 6–8 hours, stirring occasionally if possible.
6. Serve – Garnish with fresh parsley if desired and serve hot over mashed potatoes, egg noodles, or rice.

Tips for the Perfect Steak Bites

• Searing is optional but adds a rich, caramelized flavor. If skipping, place seasoned steak directly into the slow cooker.
• Cooking times vary – every slow cooker heats differently; adjust the time slightly if needed.
• Storage – Refrigerate leftovers for up to 3 days, or freeze for up to 3 months. Reheat gently to maintain tenderness.

Serving Suggestions

• Over creamy mashed potatoes to soak up the gravy.
• Tossed with buttered egg noodles for a hearty meal.
• Served with steamed rice for a simple, family-friendly dinner.
• Pair with roasted or steamed vegetables for balance.
