Your crockpot has been sitting on that shelf collecting dust. This recipe is about to change that.
Garlic butter steak bites made in the slow cooker are the kind of meal that makes people think you spent hours in the kitchen. You didn’t. Your crockpot did the heavy lifting while you went about your day.
The result? Tender, juicy pieces of steak swimming in the most ridiculously good garlic butter sauce you’ve ever had. Every bite is soft enough to melt, and that sauce? You’ll be tempted to drink it straight from the pot. (No judgment here.)
The thing that surprises most people is how little prep this takes. Under 15 minutes. Then you walk away.
What You’ll Need
For the Steak Bites
- 2 lbs sirloin steak, cut into 1-inch bite-sized cubes
- 1/2 cup (1 stick) unsalted butter, cut into slices
- 6 cloves garlic, minced (don’t even think about using less)
- 1 cup beef broth
- 2 tablespoons Worcestershire sauce
- 1 tablespoon soy sauce
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- 1 teaspoon Italian seasoning
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt (or to taste)
- 1/4 teaspoon red pepper flakes (optional, but recommended)
- 1 tablespoon cornstarch + 2 tablespoons cold water (for thickening the sauce)
- Fresh parsley, chopped, for garnish
Tools You’ll Need
- 6-quart slow cooker / crockpot
- Sharp chef’s knife and cutting board
- Measuring cups and spoons
- Small bowl (for the cornstarch slurry)
- Tongs or a large spoon for serving
Pro Tips 🔥
These are the things I wish someone had told me the first time around.
- Don’t skip the sear (if you have 5 minutes). You don’t have to sear the steak before it goes in, but if you do, you get this beautiful golden crust on each bite that adds so much flavor depth. Just a quick 60-second sear in a hot pan before they hit the crockpot is all it takes.
- Cut your steak pieces evenly. Uneven cuts mean some pieces overcook while others are still tough. Aim for uniform 1-inch cubes and they’ll all cook at the same rate.
- Use the cornstarch slurry. The sauce starts out thin. Adding the cornstarch slurry in the last 20-30 minutes of cooking turns it into something thick, glossy, and absolutely incredible. Don’t skip this step.
- Low and slow is the move. Cook on LOW for 4-5 hours rather than HIGH for 2-3. The lower temperature keeps the steak tender instead of rubbery. You have the time. Let it do its thing.
- Fresh garlic only. Pre-minced garlic from a jar works in a pinch, but fresh garlic cloves minced yourself will make this sauce taste like something from a steakhouse. It’s worth the extra 2 minutes.
How to Make Garlic Butter Steak Bites in the Crockpot
Prep time: 10-15 minutes | Cook time: 4-5 hours on LOW (or 2-3 hours on HIGH) | Serves: 4-6
Step 1: Prep the Steak
Pat your steak cubes completely dry with paper towels. This helps with browning and keeps your sauce from getting watery.
Season generously with salt and black pepper.
Step 2: Optional (But Worth It) Sear
Heat a skillet over high heat with a tiny bit of oil. Sear the steak bites for about 60 seconds per side just to get a golden crust. Do this in batches so you’re not crowding the pan.
Transfer to the crockpot.
Step 3: Build the Sauce
In the crockpot, add the minced garlic, beef broth, Worcestershire sauce, soy sauce, onion powder, smoked paprika, Italian seasoning, and red pepper flakes.
Give everything a gentle stir.
Step 4: Add the Butter
Scatter the butter slices right on top. As it melts down into the broth, it creates the most glossy, rich, garlicky sauce you can imagine.
Step 5: Cook
Place the lid on and cook on LOW for 4-5 hours or HIGH for 2-3 hours.
Resist the urge to open the lid constantly. Every time you lift it, you’re adding cooking time.
Step 6: Thicken the Sauce
About 20-30 minutes before serving, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth.
Stir the slurry into the crockpot and replace the lid. Let it cook for the remaining time until the sauce thickens up nicely.
Step 7: Serve
Taste and adjust salt if needed. Spoon over mashed potatoes, rice, or egg noodles. Garnish with fresh parsley and serve immediately.
Substitutions and Variations
Not everyone has the same pantry (or the same taste buds), so here’s how you can mix things up.
| Ingredient | Substitution |
|---|---|
| Sirloin steak | Ribeye, chuck steak, or beef tenderloin |
| Unsalted butter | Salted butter (just reduce added salt) |
| Beef broth | Chicken broth or vegetable broth |
| Soy sauce | Coconut aminos (for a lower-sodium option) |
| Fresh garlic | 1 teaspoon garlic powder (but fresh is better) |
| Red pepper flakes | A dash of cayenne pepper |
Want to switch things up? Try adding sliced mushrooms in the last hour of cooking. They soak up that garlic butter sauce and become absolutely unreal.
Make-Ahead Tips
This recipe is already easy, but here’s how to make it even more hands-off.
- Prep the night before: Cut your steak into cubes, season them, and store in an airtight container in the fridge overnight.
- Mix the sauce: Combine the broth, Worcestershire, soy sauce, and spices in a jar the night before. Refrigerate until ready to use.
- Morning assembly: Dump everything in the crockpot before you leave the house. Dinner handles itself.

What to Serve With It
The garlic butter sauce is practically begging to be soaked up by something. Here are some perfect pairings:
- Creamy mashed potatoes (the classic choice for a reason)
- Buttered egg noodles
- Steamed white rice or cauliflower rice (for a lighter option)
- Crusty bread to mop up every last drop of sauce
- Roasted broccoli or asparagus on the side to balance the richness
Diet-Friendly Swaps
- Low-carb/Keto: Serve over cauliflower mash. Skip the cornstarch and let the sauce reduce naturally.
- Dairy-free: Use vegan butter or ghee instead of regular butter.
- Gluten-free: Swap Worcestershire and soy sauce for gluten-free versions (or use coconut aminos).
Leftovers & Storage
Good news: this tastes even better the next day.
- Fridge: Store in an airtight container for up to 4 days. The sauce thickens further as it chills, which makes it extra good reheated.
- Freezer: Freeze in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
- Reheating: Warm gently on the stovetop over medium-low heat or microwave in 60-second intervals, stirring in between. Add a splash of beef broth if the sauce has thickened too much.
FAQ
Can I use frozen steak? You can, but thaw it completely first. Adding frozen meat to a slow cooker means it spends too long in the “danger zone” temperature before fully cooking. Always thaw in the fridge overnight.
My sauce is too thin. What happened? You likely skipped the cornstarch slurry step, or added it too early. Make the slurry in the last 20-30 minutes of cooking with the lid on so it properly activates.
Can I cook this on HIGH instead of LOW? Yes, but LOW is strongly recommended. Cooking on HIGH can make the steak tough and chewy. If you’re short on time, HIGH for 2-3 hours works, just expect slightly less tender bites.
What cut of steak works best for this? Sirloin is the sweet spot for budget and flavor. Ribeye gives you more fat and flavor, while chuck steak is the most budget-friendly and gets beautifully tender with the long, slow cook time.
Do I really need 6 cloves of garlic? Yes. And honestly, 8 is fine too. This is a garlic butter recipe. The garlic is the whole point.
Can I add vegetables to the crockpot? Absolutely. Baby potatoes, carrots, and mushrooms all work well. Add sturdier vegetables (like carrots and potatoes) at the beginning, and softer vegetables (like mushrooms or zucchini) in the last hour.
Is it okay to open the lid while it’s cooking? Try to resist. Every time you lift the lid, you release heat and add about 15-20 minutes to the cook time. Check on it at the end, not throughout.
Wrapping Up
There’s a reason this recipe lives rent-free in my head.
It’s the kind of dinner that makes you look like you’ve been cooking all day when all you really did was chop some steak, dump everything in a pot, and walk away. The garlic butter sauce alone is worth making this recipe just once.
And once is rarely all it takes. 😄
Give it a try this week and come back to tell me how it went. Did you sear the steak first? Did you add mushrooms? Did someone in your house hover over the crockpot asking “is it ready yet?” (Because same.)
