Why This Recipe Works

If you’re used to cooking steak quickly in a skillet, you’ll love how the slow cooker turns even lean cuts like sirloin into fork-tender bites. The garlic butter keeps the meat juicy while infusing every bite with flavor.

Steak bites + garlic butter + slow cooker = one seriously delicious dinner with almost no effort.

Ingredients for Crockpot Garlic Butter Steak Bites

3 lbs sirloin steak, cut into bite-sized chunks
1 teaspoon salt
½ teaspoon black pepper
¼ teaspoon garlic powder
2 tablespoons olive oil, to sear beef
6 garlic cloves, minced
1 stick butter (8 tablespoons)
¼ cup chopped parsley, for topping

Pro Tip: Pat your steak pieces dry before seasoning and searing. That helps create a better crust and keeps the butter sauce from becoming greasy.

How to Make Crockpot Garlic Butter Steak Bites

Season the steak. Blot the steak with a paper towel to remove excess moisture. Cut into small pieces. In a large bowl, toss the steak pieces with salt, pepper, and garlic powder until evenly coated.
Sear for flavor. Heat a large skillet over medium-high heat and add olive oil. Sear steak bites for 2–3 minutes on both sides until browned. (Don’t overcrowd the pan, and work in batches if needed.) This beautiful sear adds depth of flavor to your Garlic Butter Steak Bites. Transfer to your slow cooker.

Add garlic and butter. Add minced garlic and butter to the slow cooker.
Cook low and slow. Cover and cook on low for 6–8 hours or high for 3–4 hours.
Serve and enjoy. Stir before serving and top with fresh parsley.

Pro Tip: If you want a thicker sauce, remove the lid for the last 30 minutes of cooking to let it reduce slightly.

Recipe Variations to Try

Want to change things up or make this dish your own? Here are a few easy ways to customize your Garlic Butter Steak Bites and how to serve them:

Add a little heat: Sprinkle in red pepper flakes to give the garlic butter sauce a subtle spicy kick.
Try a different cut: Swap the top sirloin for beef stew meat, cubed steak, or beef tenderloin—the slow cooker will make it just as tender and flavorful.
Adjust the garlic: Love garlic? Add a couple more cloves. Prefer it mild? Use a little less—this recipe is flexible.
Make extra sauce: You don’t need broth, but adding ¼ cup of beef broth creates more buttery sauce to pour over mashed potatoes or rice.
Thicken and boost flavor: Stir in a packet of au jus mix or brown gravy mix before cooking for a richer, thicker sauce.

FAQs about Garlic Steak Bites

Absolutely. Sirloin works great, but you can also use stew meat, strip steak, or ribeye for an extra tender result.
