Key Ingredients for Slow Cooker Garlic Butter Steak Bites

See recipe card below for full list of measurements, ingredients, and instructions.

Sirloin Steak

Sirloin steak gives this recipe its signature juicy, beefy flavor. Cut the steak into even, bite-sized cubes for perfect tenderness and even cooking. If sirloin isn't available, try ribeye for extra richness or top round as a leaner, more budget-friendly alternative. Just avoid stew meat, as it can turn stringy in the slow cooker.

Fresh Garlic

Freshly minced garlic infuses the sauce with irresistible, aromatic depth. Don't skimp! Jarred garlic works in a pinch, but freshly minced offers a more vibrant flavor. For extra garlic kick, add a couple more cloves or finish with roasted garlic.

Unsalted Butter

Butter is the key to silky, indulgent sauce that clings to every bite. Use unsalted so you can control the saltiness, especially since broth and steak both add salt too. Ghee or plant-based butter can work for dairy-free needs, though flavor will change slightly.

Low-Sodium Beef Broth

Beef broth keeps the steak moist and helps create that mouthwatering sauce. Go for low-sodium to prevent the dish from becoming too salty. If you don't have beef broth, chicken broth or even a splash of dry red wine make solid substitutes.

Worcestershire Sauce

This pantry staple brings deep umami, slight tang, and just a hint of sweetness, rounding out all the flavors. Soy sauce can be used for a pinch-hitter substitute, but the Worcestershire gives a more complex, classic steakhouse flavor.

Instructions for Slow Cooker Garlic Butter Steak Bites

See recipe card below for full list of measurements, ingredients, and instructions.

Prep the Steak and Ingredients

Cut the sirloin steak into uniform 1-inch cubes so each piece cooks evenly and stays juicy. Mince the fresh garlic, melt the butter in the microwave, and have your seasonings ready to go.

Make the Garlic Butter Mixture

In a bowl, whisk together the melted butter, minced garlic, beef broth, Worcestershire sauce, salt, pepper, onion powder, and smoked paprika. Mix well to get all those flavors combined-your kitchen will already start to smell amazing!

Layer Everything in the Slow Cooker

Add the cubed steak to your slow cooker in an even layer. Pour the garlic butter mixture over the top, gently tossing so every piece is coated. Don't worry if the sauce seems thin-it will thicken and concentrate as it cooks.

Slow Cook Until Tender

Cover and cook on LOW for 3 hours, until steak bites are melt-in-your-mouth tender. (Avoid cooking on HIGH; low and slow is best for tenderness.) Stir halfway through if you can, just to coat everything again.

Serve and Garnish

Once they're cooked, give your steak bites a gentle stir and spoon them onto a plate or over your favorite base. Pour the garlicky butter sauce all over and sprinkle with fresh parsley for a burst of color and freshness.

Recipe Variations

Give It a Kick

Love some heat? Add ½ teaspoon of crushed red pepper flakes or a diced jalapeño to the butter mixture for a mild but noticeable spicy kick.

Mushroom & Onion Twist

Toss in a cup of sliced mushrooms and half an onion, thinly sliced, before cooking. They'll soak up all the amazing garlic butter and add extra bulk and savory flavor to the dish.

Make It Dairy Free

Swap the butter for a high-quality plant-based substitute or use olive oil. The flavor will be a bit different-lighter and less creamy, but still delicious.

Herb Lovers Version

Enhance your steak bites with extra herbs like fresh rosemary or thyme. Add a sprig or two in with the steak for aromatic, earthy undertones.

Low-Carb & Keto

Skip the Worcestershire, and add a splash of coconut aminos instead for a lower-carb and keto-friendly alternative. Serve with cauliflower mash for a hearty, low-carb dinner.

Serving Suggestions

These steak bites are mouthwatering on their own, but truly shine served over creamy mashed potatoes, steamed rice, or buttery egg noodles. Pair with roasted vegetables or a fresh green salad for balance and color. Don't forget extra crusty bread to mop up every drop of the garlicky butter sauce, and finish with a sprinkle of fresh parsley.

Storage and Reheating

Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm steak bites gently in a skillet over medium-low heat with a splash of broth or water, or microwave in 30-second bursts until heated through. You can also freeze cooked steak bites (and sauce) in a freezer-safe container for up to 2 months-thaw overnight in the fridge and reheat as above.

Frequently Asked Questions About Slow Cooker Garlic Butter Steak Bites (FAQ)

Q: Can I use a different cut of beef besides sirloin?

A: Absolutely! Ribeye will be even richer and more tender, while top round or chuck roast are budget-friendly choices. Just ensure bite-sized, even pieces.

Q: Can I cook these steak bites on HIGH instead of LOW?

A: I recommend sticking with LOW for 3 hours for the juiciest, most tender results. Cooking on HIGH may make the steak tough.

Q: Will the garlic butter sauce thicken in the slow cooker?

A: The sauce lightly thickens but stays pourable and buttery. If you'd like it thicker, remove the steak after cooking and simmer the sauce on the stovetop for a few minutes.
