Ingredients You’ll Need
All the ingredients in this Garlic Butter Steak Bites in Crockpot Recipe come together beautifully to build layers of savory, comforting flavors. I like to shop for fresh garlic and a good-quality sirloin to make sure each bite is tender and flavorful.

- Sirloin steak: Choose fresh sirloin trimmed of excess fat for tender steak bites.
- Kosher salt: Its coarse texture helps season steak evenly and enhances natural flavors.
- Black pepper: Freshly ground works best for that subtle kick.
- Vegetable oil: Its high smoke point is perfect for searing without burning.
- Sweet onion: Adds a mild, natural sweetness to balance the richness.
- Garlic: Thinly sliced for a mellow, aromatic punch throughout the dish.
- Unsalted beef stock: Keeps the steam going in the slow cooker and deepens the beefy flavor.
- Au jus gravy mix: This simple addition intensifies the savory sauce without much effort.
- Unsalted butter: Sliced thin to melt evenly over the steak bites for ultimate richness.
Variations
I love how flexible this Garlic Butter Steak Bites in Crockpot Recipe is. You can play around with seasonings or even swap some ingredients based on what you have in your kitchen or dietary preferences.
- Adding Mushrooms: I sometimes toss in sliced cremini or button mushrooms when adding onions and garlic for an earthy note that pairs wonderfully with the steak.
- Spicy Kick: A pinch of crushed red pepper flakes mixed into the gravy mix gives a subtle heat that my family goes crazy for.
- Herbs Boost: Fresh thyme or rosemary can bring an aromatic lift; I add them on top before slow cooking for more depth.
- Substitute Steaks: Flank steak or chuck steak work well too – just watch the slow cook time slightly so it doesn’t turn too soft or tough.
How to Make Garlic Butter Steak Bites in Crockpot Recipe
Step 1: Season and Sear the Steak Bites
Start by cutting your sirloin steak into bite-sized pieces, then season them thoroughly with kosher salt and black pepper. Here’s the trick I learned: searing the steak bites in a hot skillet before tossing them in the crockpot is a must—it locks in flavor and adds that beautiful brown crust we all love. Heat your vegetable oil until it’s shimmering but not smoking, then work in batches to avoid overcrowding the pan. You’re aiming to brown the edges without cooking the steak all the way through since it will finish cooking slowly later. If you notice the pan getting too dry, add a little more oil.
Step 2: Build the Layers in Your Crockpot
Once the steak pieces are perfectly browned, transfer them to your slow cooker. Add the thinly sliced sweet onion and garlic—you want those slices to infuse the slow-cooked sauce with their mellow sweetness and signature aroma. Pour in the beef stock, then evenly sprinkle the au jus gravy mix on top. Lay the slices of unsalted butter over everything; as it melts, it’ll add that irresistible buttery richness. No stirring just yet! Cover the lid and set your crockpot to high for 3 to 4 hours (or low 6 to 8 hours if you prefer). If you can, stir gently every hour to keep flavors mingling.
Step 3: Serve and Enjoy
When your kitchen starts smelling like garlic butter heaven, you’re ready to serve. These steak bites shine served over creamy mashed potatoes, egg noodles, or steamed rice—the juices soak right in, making the side dishes extra comforting. I absolutely love serving this for weekend dinners or when friends come over because it’s so satisfying yet simple to plate.
Pro Tips for Making Garlic Butter Steak Bites in Crockpot Recipe
- Don’t Skip the Sear: I used to think slow cooking alone was enough, but searing really adds depth and texture you just can’t get otherwise.
- Thin Slices of Garlic: Slicing garlic instead of mincing gives the sauce those beautiful mellow pockets of garlicky flavor instead of harsh bursts.
- Use a Good Au Jus Mix: It’s a game changer. I tried it without once, and it lacked that rich beefy punch this recipe is known for.
- Don’t Overcrowd the Pan: When searing, work in small batches to get an even brown crust on each piece—crowding leads to steaming instead.
How to Serve Garlic Butter Steak Bites in Crockpot Recipe

Garnishes
Whenever I serve these steak bites, I like to finish with a sprinkle of freshly chopped parsley or a light dusting of cracked black pepper. The green parsley not only brightens the plate visually but also adds a fresh balance to the rich garlic butter sauce.
Side Dishes
I usually pair this with creamy mashed potatoes because they soak up that luscious butter sauce perfectly, but egg noodles or steamed jasmine rice work beautifully too. One of my favorite combos is roasted asparagus on the side—it adds a fresh, crisp veggie element that cuts through the richness.
Creative Ways to Present
For special occasions, I like to serve these steak bites family-style in a rustic cast iron skillet right on the table. It makes everything feel extra warm and inviting, plus guests can help themselves to as much saucy steak as they want. A crusty baguette on the side for mopping up the buttery juices is a must-have in this setup!
Make Ahead and Storage
Storing Leftovers
I always refrigerate leftovers in an airtight container and try to enjoy them within 3 days. The sauce thickens a little in the fridge, but a splash of beef stock when reheating brings it back to that luscious consistency.
Freezing
This Garlic Butter Steak Bites in Crockpot Recipe freezes surprisingly well. I portion mine into freezer-safe containers and freeze for up to 3 months. When defrosting, I thaw overnight in the fridge and reheat gently on the stove to keep the steak tender.
Reheating
To reheat, I warm the steak bites slowly in a skillet over low heat, adding a splash of broth if needed to loosen the sauce. This method keeps the steak juicy and the sauce silky without drying it out or overcooking.
FAQs
-
Can I use a different cut of steak for this recipe?
Absolutely! While sirloin steak is ideal for its tenderness and flavor, you can use flank steak or chuck steak as well. Just keep in mind that chuck might benefit from a slightly longer cooking time for maximum tenderness, and flank steak cooks fairly quickly, so monitor closely to avoid overcooking.
-
Do I have to sear the steak before slow cooking?
Searing isn’t strictly mandatory, but I highly recommend it. It adds a delicious caramelized crust and enhances the overall flavor profile. Skipping this step can result in steak bites that are less flavorful and a bit pale.
-
Can I make this recipe in an Instant Pot instead of a crockpot?
Yes! You can use the sauté function to sear the steak and then pressure cook with the other ingredients for about 20-25 minutes on high. Just be sure to follow your Instant Pot’s manual for pressure release instructions. The result will be equally tender and flavorful.
-
What can I serve with Garlic Butter Steak Bites?
This dish pairs wonderfully with mashed potatoes, egg noodles, or rice to soak up all that buttery sauce. Roasted or steamed vegetables like asparagus, green beans, or broccoli add a fresh contrast and make for a balanced meal.
-
How long do leftover Garlic Butter Steak Bites keep?
When stored properly in an airtight container, leftovers stay good in the refrigerator for up to 3 days. For longer storage, freeze them for up to 3 months.
Final Thoughts
This Garlic Butter Steak Bites in Crockpot Recipe holds a special place in my kitchen rotation because it’s one of those meals that manages to be both indulgent and effortless.
