Ingredients You’ll Need

Each ingredient in this Slow Cooker Garlic Butter Steak Bites (+Video) Recipe plays a crucial role in building layers of flavor—from the juicy sirloin to the garlicky butter sauce and the savory au jus gravy. I recommend using fresh garlic and a good-quality beef stock to really make this dish pop.

• Sirloin steak: Choose a tender cut like sirloin; it holds up well in slow cooking without drying out.
• Kosher salt: I always prefer kosher salt for a clean seasoning that doesn’t overpower.
• Black pepper: Freshly ground black pepper adds a hint of warmth and spice.
• Vegetable oil: Use a neutral oil with a high smoke point for searing the steak.
• Sweet onion: Thinly sliced for a little natural sweetness that balances the garlic.
• Garlic cloves: Thin slices soak the sauce with bold, aromatic flavor.
• Unsalted beef stock: Adds depth and richness without excessive salt.
• Au jus gravy mix: This pantry staple instantly turns the juices into a velvety gravy.
• Unsalted butter: Thin slices melt throughout for that luscious garlic butter finish.

Variations

I love playing around with this recipe depending on the season or what I have on hand. The beauty of this Slow Cooker Garlic Butter Steak Bites (+Video) Recipe is how easily it adapts to your taste preferences—so don’t be shy about making it your own.

• Spicy Kick: I sometimes add a pinch of red pepper flakes for a little heat, which my family absolutely loves.
• Mushroom Addition: Toss in sliced mushrooms with the onions for a lovely earthy twist.
• Gluten-Free: Just swap the au jus mix for a gluten-free gravy seasoning, and you’re good to go.
• Herb Flavor: Fresh herbs like thyme or rosemary lifted the flavor when sprinkled on top just before serving.

How to Make Slow Cooker Garlic Butter Steak Bites (+Video) Recipe

Step 1: Season and Sear the Steak

Start by cutting your sirloin into bite-sized pieces and tossing them with kosher salt and black pepper—it’s the simplest way to boost flavor. Next, heat a large skillet over medium-high heat and add vegetable oil. When it’s smoking hot, sear the steak pieces in batches; you want to get a nice brown crust on each side but not fully cook them. This searing step is what brings out that incredible depth of flavor in this Slow Cooker Garlic Butter Steak Bites (+Video) Recipe, so don’t skip it!

Step 2: Layer Ingredients in the Slow Cooker

Once your steak is nicely browned, transfer all the pieces to your slow cooker. Add the thinly sliced sweet onion and garlic on top. Pour in the unsalted beef stock, sprinkle the au jus gravy mix uniformly over everything, and top with those thin slices of unsalted butter. This layering sets the stage for that garlicky butter sauce that’s the heart of the dish.

Step 3: Slow Cook to Perfection

Cover the slow cooker and cook on high for 3-4 hours or on low for 6-8 hours. I like to stir it once every hour if I’m around, just to redistribute everything and help the butter melt evenly into the sauce. The steak will come out juicy, tender, and bursting with garlicky buttery goodness—you really can’t rush this part.

Step 4: Serve and Enjoy

Once the cooking time is up, give everything a gentle stir to coat the steak bites in the buttery sauce. Serve immediately while it’s nice and hot. This Slow Cooker Garlic Butter Steak Bites (+Video) Recipe pairs beautifully with creamy mashed potatoes, egg noodles, or even steamed rice to soak up all that savory sauce. Prepare for anyone around you to ask for seconds!

Garnishes

I usually finish this dish with a sprinkle of freshly chopped parsley—it adds a lovely pop of color and a fresh, herby brightness that balances the rich garlic butter sauce. Sometimes I’ll add a few cracked black peppercorns on top to give a slight spicy kick. Both are simple touches that elevate the presentation and flavor.

Side Dishes

My go-to favorites alongside these steak bites are creamy mashed potatoes or buttered egg noodles—they soak up that buttery sauce beautifully. Steamed green beans or a crisp side salad add a fresh, crunchy contrast that rounds out the meal perfectly. I also love serving it over garlic rice for an easy one-pot feel.

Creative Ways to Present

For special occasions, I’ve served this recipe as a steak bite appetizer, skewered with toothpicks and arranged around a garlic butter dipping sauce. It’s always a hit at parties and feels extra indulgent when plated on a wooden board with artisan bread and a glass of red wine. Making a “steak and sauce” grazing board has become one of my favorite creative ways to showcase it.

Make Ahead and Storage

Storing Leftovers

I usually store leftover steak bites in an airtight container in the fridge for up to 3 days. The rich sauce thickens as it cools, which actually makes reheating better, since the flavors settle beautifully overnight. Just give it a gentle stir before reheating to loosen it up.

Freezing

Freezing these steak bites works well if you want a make-ahead meal. Portion them out into freezer-safe containers, and they’ll keep nicely for up to 3 months. I recommend thawing overnight in the fridge before reheating for best texture and flavor retention.

Reheating

To reheat, I like warming the steak bites gently in a skillet over low heat or in the microwave with a splash of beef stock or water to keep the sauce silky. Stir occasionally and heat just until warmed through—this helps avoid overcooking the steak and keeps it tender.
