How to Make the Slow Cooker Garlic Butter Steak Bites and Potatoes

Step 1: Give the Steak a Quick Sear
Heat the olive oil in a skillet over medium-high heat. Add your sirloin steak bites and sear them for just 1 to 2 minutes. We just want a gorgeous, light brown crust on the outside—we are not cooking them fully here! This little step locks in the texture and flavor.
Step 2: Layer the Potatoes and Steak in the Slow Cooker
Place all of your halved baby potatoes right into the bottom of the slow cooker. Then, gently nestle the seared steak bites right on top of the potatoes.
Step 3: Mix Up the Dreamy Garlic Butter
In a small bowl, whisk together the melted butter, minced garlic, smoked paprika, dried thyme, dried rosemary, onion powder, salt, and pepper. Give it a good swirl until it’s perfectly combined and smelling amazing.
Step 4: Drench and Cook Low and Slow
Pour that gorgeous garlic butter mixture evenly all over the steak and potatoes in the slow cooker. Cover your slow cooker and cook on low for 5–6 hours or on high for 2.5–3 hours, until the potatoes are beautifully tender.
Step 5: Toss and Finish with Fresh Parsley
Once the cooking time is up, give the whole thing a gentle toss to make sure everything is coated in that amazing sauce. Sprinkle generously with fresh chopped parsley for a bright flavor lift, and get ready to serve this masterpiece!
Pro Tips for Making the Recipe
- Don’t Skip the Sear: That quick sear in Step 1 is important! It gives the steak bites some structure and a depth of flavor that a slow cooker alone can’t achieve. Just make sure it’s only a light sear, not a full cook.
- Layering is Key: Place the potatoes on the bottom—they can handle the direct heat and moisture better than the steak and they need a little longer to become perfectly tender.
- Taste and Adjust: Before serving, give the sauce a quick taste. Slow cooking often mellows seasoning, so you may want a final pinch of salt and pepper to make those flavors sing!
- Go Big on the Garlic: We use a lot of garlic here, and it’s worth it. When cooked for hours, the raw bite mellows into a deep, comforting sweetness.
How to Serve

This is a true one-pot meal, but it pairs wonderfully with a few simple additions to complete your dinner plate!
- Fresh Greens: Balance the richness with a simple, crisp green salad dressed with a light vinaigrette.
- Crusty Bread: You must have something to soak up that unbelievable, buttery garlic sauce left at the bottom of the cooker. A crusty French baguette is perfect for dipping!
- Roasted Veggies: If you want extra greens, a side of simple steamed green beans or roasted asparagus would be heavenly.
Make Ahead and Storage
Storing Leftovers
Place any leftovers into an airtight container and store them in the refrigerator for up to 3 days.
Freezing
You can freeze leftovers, but know that the potatoes may have a slightly different texture when thawed. Place the cooled mixture in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat leftovers gently in the microwave or, even better, in a pan on the stovetop over low heat until warmed through, adding a small pat of butter if it seems dry.
FAQs
1. Is it okay if my steak looks pink after searing?
Absolutely! The goal of searing is only to develop flavor and color on the outside of the meat, not to cook it through. The steak will finish cooking completely during the long, slow-cooker process, resulting in incredibly tender, juicy bites. If you cooked it fully during the sear, it would become tough in the slow cooker—so a quick sear is perfect.
2. Can I use a different cut of beef for this recipe?
Yes, you can! While sirloin is a fantastic, flavorful choice, you can also use chuck roast, which will become fall-apart tender, or even flank steak, cut into cubes. The key is to use a cut that benefits from the low-and-slow cooking method, which helps break down connective tissue for ultimate tenderness.
3. What can I use if I don’t have fresh herbs?
If you don’t have fresh parsley for the garnish, no worries! You can substitute the fresh parsley with dried parsley in the butter mix, or simply use an extra pinch of dried thyme and rosemary instead. However, the fresh parsley at the end really does add a vibrant finish, so grab some if you can!
4. Can I add other vegetables to this recipe?
Of course! Feel free to toss in some hearty vegetables like sliced carrots or parsnips. Make sure to cut them into similar sizes as the potatoes so they cook evenly and become tender at the same time. Add them right along with the potatoes at the bottom of the slow cooker.
