Garlic Parmesan Steak Bites with Mashed Potatoes is a rich, satisfying meal that combines juicy, pan-seared steak pieces tossed in garlicky butter and parmesan with a side of creamy mashed potatoes. I love how this dish hits all the comfort food notes—tender beef, bold flavors, and buttery mashed potatoes to soak it all up.

Why You’ll Love This Recipe

I like this recipe because it’s fast, flavorful, and feels like a steakhouse dinner without all the fuss. The steak bites are seared quickly, then finished in a savory garlic-parmesan butter that coats every piece in rich flavor. Pairing them with mashed potatoes creates that perfect balance of texture—creamy, tender, and crispy all in one bite.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the steak bites:

• Sirloin steak or ribeye, cut into bite-sized cubes
• Salt and pepper
• Garlic powder
• Olive oil or butter (for searing)
• 3–4 cloves garlic, minced
• 3 tablespoons butter
• ¼ cup grated Parmesan cheese
• Chopped fresh parsley (optional for garnish)

For the mashed potatoes:

• Yukon gold or russet potatoes, peeled and chopped
• Butter
• Milk or heavy cream
• Garlic (optional, for extra flavor)
• Salt and pepper

Directions

1. I start by boiling the potatoes in salted water until fork-tender, about 15–20 minutes.
2. While the potatoes cook, I season the steak bites with salt, pepper, and garlic powder.
3. I heat oil or butter in a large skillet over medium-high heat and sear the steak bites in batches to get a nice crust—about 2 minutes per side. I remove them and set aside.
4. In the same skillet, I lower the heat and add the butter and minced garlic. I sauté until fragrant, about 1 minute.
5. I return the steak to the skillet, toss to coat in the garlic butter, and sprinkle with Parmesan cheese. I stir just until everything is glossy and coated.
6. Once the potatoes are done, I drain them and mash with butter, warm milk or cream, salt, and pepper until smooth. I add roasted garlic for more depth if I’m feeling fancy.
7. I serve the steak bites over a bed of mashed potatoes, spooning extra garlic butter from the pan over the top and sprinkling with parsley.

This recipe serves 4.
Prep time: 15 minutes
Cook time: 20–25 minutes
Total time: About 40 minutes

Variations

Sometimes I add a splash of Worcestershire or balsamic vinegar to the skillet for added depth. I’ve also made a spicy version by adding red pepper flakes to the garlic butter. For a lighter option, I swap the mashed potatoes with cauliflower mash or steamed veggies.

storage/reheating

I store leftovers in the fridge for up to 3 days. To reheat, I warm the steak bites gently in a skillet with a splash of broth or butter to keep them moist. The mashed potatoes reheat well in the microwave or stovetop with a bit of milk stirred in.

FAQs

What cut of steak is best for this?

I use sirloin or ribeye because they stay tender and sear beautifully. Strip steak or tenderloin also work well.

Can I make this ahead of time?

Yes, I prep the steak and even cook the mashed potatoes in advance. I reheat everything gently and finish the steak in garlic butter just before serving.

What kind of Parmesan should I use?

I use freshly grated Parmesan for the best flavor and texture—it melts better and gives a richer finish than pre-grated.

Can I make this without butter?

Yes, I’ve used olive oil and it still works, but butter really enhances the richness. A dairy-free butter alternative also works fine.

What sides go well with this dish?

I usually stick with mashed potatoes, but I’ve also served it with roasted vegetables, creamed spinach, or a side salad for freshness.

Conclusion

Garlic Parmesan Steak Bites with Mashed Potatoes is the ultimate comfort meal—quick to make, loaded with flavor, and always a crowd-pleaser. Whether I’m serving it for a weeknight dinner or something a little special, it brings big steakhouse vibes with none of the hassle.
