Ingredients You’ll Need
The beauty of this Garlic Butter Steak Bites and Cheesy Smashed Potatoes Recipe is how much flavor you get from such a simple lineup of ingredients. Each component plays a crucial role, from the rich butter that gives the steak its silky finish to the sharp cheddar that takes the potatoes over the top. Here’s what you’ll need and why each ingredient matters:
- Sirloin Steak: Tender and flavorful, sirloin is perfect for quick searing and stays juicy in bite-sized pieces.
- Olive Oil: Helps sear the steak and crisp up the potatoes, adding a subtle fruity note.
- Unsalted Butter: The base of the irresistible garlic butter sauce for the steak bites.
- Garlic: Freshly minced garlic brings big, bold flavor to both the steak and the potatoes.
- Fresh Parsley: Adds a burst of color and a fresh, herby finish to the steak bites.
- Salt and Pepper: Simple seasonings that bring out the natural flavors in both steak and potatoes.
- Baby Potatoes: Red or gold potatoes are ideal for smashing and roasting to crispy perfection.
- Garlic Powder: Gives the potatoes a gentle, savory depth without overpowering the cheese.
- Shredded Cheddar Cheese: Melts beautifully over the potatoes, creating a gooey, cheesy crust.
- Grated Parmesan Cheese: Adds a nutty, salty kick to balance the richness of the cheddar.
- Chopped Chives or Green Onions (optional): Lend a fresh, oniony bite and a pop of color as a garnish.
How to Make Garlic Butter Steak Bites and Cheesy Smashed Potatoes Recipe
Step 1: Cook and Smash the Potatoes
Start by boiling your baby potatoes in a big pot of salted water. You want them fork-tender but not falling apart, so keep an eye on them after 15 minutes. Once they’re ready, drain and let them cool just until you can handle them. Space them out on a parchment-lined baking sheet, then gently press each one down with the bottom of a glass or fork. The goal is flat and rustic, with some cracks for extra crispy edges.
Step 2: Season and Roast the Potatoes
Drizzle the smashed potatoes with olive oil and sprinkle on garlic powder, salt, and pepper. Slide the tray into a hot oven at 425°F and let them roast for 20 to 25 minutes. You’ll know they’re ready when the edges are golden and crispy. Right before serving, shower them with shredded cheddar and Parmesan, then return to the oven for a few more minutes to melt the cheese into a bubbly, irresistible layer.
Step 3: Prepare and Sear the Steak Bites
While the potatoes roast, pat your steak cubes dry and season generously with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Add the steak in a single layer, working in batches as needed to avoid crowding. Sear the bites for about 2 to 3 minutes per side—just enough for a deep brown crust and juicy middle. Remove the steak from the pan while you make the garlic butter.
Step 4: Make the Garlic Butter Sauce
Lower the heat to medium and add the butter and minced garlic to the same skillet. Stir constantly for a minute or two, letting the garlic infuse the butter without burning. Return the steak bites to the pan and toss well, spooning the garlicky butter over every piece. Finish with chopped parsley for a pop of freshness.
Step 5: Serve and Enjoy
Arrange the steak bites alongside the cheesy smashed potatoes while everything is still hot and melty. The flavors complement each other so well, you’ll want a bit of both in every bite. This Garlic Butter Steak Bites and Cheesy Smashed Potatoes Recipe is best enjoyed fresh, so gather everyone around the table and dig in!
How to Serve Garlic Butter Steak Bites and Cheesy Smashed Potatoes Recipe

Garnishes
Finish your plate with a generous sprinkle of fresh chives, green onions, or extra parsley for a burst of color and a hint of brightness. If you like a touch of heat, a pinch of red pepper flakes or a drizzle of hot sauce can wake up the flavors even more.
Side Dishes
This hearty Garlic Butter Steak Bites and Cheesy Smashed Potatoes Recipe can easily stand alone, but a simple green salad, roasted asparagus, or steamed broccoli makes a lovely, fresh counterpoint. A side of garlic bread never hurts if you want to soak up all that extra buttery sauce.
Creative Ways to Present
Serve the steak bites and potatoes family-style on a big platter for a casual gathering, or portion onto individual plates for a more elegant touch. For parties, you can even skewer the steak bites and serve the cheesy potatoes in mini cups for a fun, shareable appetizer version.
Make Ahead and Storage
Storing Leftovers
If you find yourself with extras, store steak and potatoes in separate airtight containers in the refrigerator. The steak will keep well for up to 3 days, and the potatoes for about 4 days. Keeping them separate helps maintain their textures and makes reheating easier.
Freezing
For the best results, freeze only the steak bites. Arrange them in a single layer on a baking sheet to freeze individually, then transfer to a freezer bag for up to 2 months. The cheesy potatoes can be frozen, but their texture may change—expect them to be a bit less crispy after thawing.
Reheating
Warm steak bites gently in a skillet over low heat with a little extra butter to keep them juicy. For potatoes, pop them in the oven or toaster oven at 400°F until heated through and the cheese is bubbly. Avoid the microwave if you can—it tends to make the potatoes soggy and the steak rubbery.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While sirloin works beautifully for its tenderness and flavor, you can substitute ribeye, strip steak, or even tenderloin if you’re feeling fancy. Just make sure to cut the steak into even cubes for even cooking.
Is there a way to make this recipe gluten-free?
Yes, this Garlic Butter Steak Bites and Cheesy Smashed Potatoes Recipe is naturally gluten-free as long as you double-check your cheese and seasonings. If you add extra sauces, be sure they’re gluten-free as well.
Can I prep any components ahead of time?
Definitely! You can boil and smash the potatoes a day in advance, then roast and top with cheese just before serving. You can also cube and season the steak ahead of time, storing it covered in the fridge until you’re ready to cook.
What’s the best way to get crispy potatoes?
For ultra-crispy results, make sure your potatoes are fully dry before smashing and roasting. Don’t skimp on the olive oil, and give them plenty of space on the baking sheet so the edges can crisp up instead of steaming.
Can I add other cheeses to the potatoes?
Absolutely! Feel free to mix in mozzarella for extra meltiness, or a sharp white cheddar for tang. Even a sprinkle of crumbled blue cheese can add a bold twist if you’re feeling adventurous.

If you’re looking for a meal that’s as satisfying as it is simple, the Garlic Butter Steak Bites and Cheesy Smashed Potatoes Recipe will quickly win a spot in your regular rotation.
