Gathering these ingredients is as easy as it is important because each one plays a crucial role in making this dish truly spectacular. From the perfectly seasoned steak bites to the creamy sauce and cheesy mashed potatoes, every element works together harmoniously.

2 lbs steak filet, ribeye, or sirloin: Choose your favorite cut for tender and juicy bites.
4-5 tablespoons avocado oil: Ideal for high-heat searing thanks to its high smoke point.
5 tablespoons butter (divided): Adds richness and depth to both the steak and sauce.
10 cloves garlic (minced and divided): The soul of the dish, infusing every bite with unbeatable flavor.
1.5 cups heavy cream: Creates the smooth, velvety Parmesan cream sauce.
2 green onions (diced): Adds freshness and a mild bite to the sauce.
1 teaspoon red pepper flakes: Provides just enough heat to excite the palate without overwhelming.
2/3 cup Parmesan cheese (grated/shredded/shaved): Essential for the savory cream sauce with a sharp finish.
4 lbs russet potatoes: The base for ultra-creamy, fluffy mashed potatoes.
1 cup half and half (warmed): Ensures your mashed potatoes are smooth and creamy.
6 tablespoons salted butter (melted): Melts right into the potatoes for a rich texture.
3/4 cup Monterey Jack cheese (or mozzarella, pepper jack): Melts beautifully for cheesy, gooey mashed potatoes.
1 teaspoon garlic powder: Enhances the flavor of the potatoes with subtle garlicky notes.
3/4 teaspoon salt and 1/2 teaspoon black pepper: For seasoning the potatoes perfectly.
Blackened seasoning blend: Smoked paprika, cayenne pepper, onion powder, garlic powder, black pepper, salt, dried thyme, and oregano for a perfectly spiced steak.

How to Make Garlic Butter Steak Bites with Parmesan Cream Sauce & Cheesy Mashed Potatoes Recipe

Step 1: Prepare the Blackened Seasoning

Mix together smoked paprika, cayenne pepper, onion powder, garlic powder, ground black pepper, salt, dried thyme, and dried oregano in a small bowl. This homemade blend is the star seasoning that gives your steak bites a smoky, spicy kick that perfectly complements the rich garlic butter.

Step 2: Prep the Cheesy Mashed Potatoes

Peel and cube the russet potatoes, then boil them in salted water until fork-tender. Drain and return to the hot pot. Mash the potatoes while warming the half and half and melting the butter. Slowly add the warm half and half and melted butter to the potatoes. Stir in garlic powder, salt, pepper, and shredded cheese until everything is creamy and gooey. Keep them warm while you focus on the steak.

Step 3: Cook the Steak Bites

Cut your chosen steak into bite-sized cubes and generously toss them in avocado oil and the blackened seasoning blend. Heat a large skillet over medium-high and sear the steak bites in batches to avoid crowding, allowing a rich crust to form. This high-heat sear locks in juices for those tender, flavorful bites you crave.

Step 4: Make the Garlic Butter Parmesan Cream Sauce

In the same skillet, lower the heat and add butter along with minced garlic—cook gently until fragrant and golden. Pour in the heavy cream, then sprinkle in Parmesan cheese. Add diced green onions and red pepper flakes for a bit of freshness and heat. Stir continuously until the sauce thickens into a smooth, creamy dream that you’ll want to drizzle over every bite of steak.

Step 5: Combine and Serve

Return the perfectly seared steak bites to the skillet and toss to coat with the luxurious Parmesan cream sauce. Spoon the cheesy mashed potatoes onto serving plates and top with your saucy steak bites. This combination is sheer comfort food bliss.

Garnishes

Fresh herbs like chopped parsley or extra diced green onions add a pop of color and freshness that brightens this rich dish. A sprinkle of freshly cracked black pepper or a light dusting of smoked paprika can add a final touch of flavor and visual appeal.

Side Dishes

Pair this decadent main with a crisp green salad or roasted vegetables for a balanced meal. Simple steamed asparagus, roasted Brussels sprouts, or sautéed green beans with garlic make fantastic complements without stealing the spotlight from your star dish.

Creative Ways to Present

For an elegant dinner, serve the steak bites and mashed potatoes in shallow bowls with the cream sauce drizzled artistically. Alternatively, layer mashed potatoes with steak in individual ramekins for a charming, portioned presentation that’s perfect for entertaining guests.

Make Ahead and Storage

Storing Leftovers

Store any leftover steak bites, sauce, and cheesy mashed potatoes in airtight containers in the refrigerator for up to 3 days. Keeping the sauce and steak together helps maintain flavor and moisture.

Freezing

The mashed potatoes freeze very well on their own; store them in freezer-safe containers for up to 3 months. It’s best to freeze the steak bites and Parmesan cream sauce separately in portioned containers to preserve texture and taste.

Reheating

Reheat the mashed potatoes gently on the stovetop or microwave with a splash of half and half to return their creamy texture. Warm the steak bites and sauce slowly in a skillet over low heat until heated through, stirring occasionally to avoid separating the sauce.

FAQs

Can I use a different cut of steak for this recipe?

Absolutely! Ribeye, sirloin, filet, or even strip steak will work beautifully. Just make sure to cut the meat into evenly sized bites so they cook quickly and uniformly.

Is it possible to make the Parmesan cream sauce dairy-free?

You can try substituting heavy cream with coconut cream and using a dairy-free butter alternative, but keep in mind that the flavor and texture will be different from the original rich sauce.

How spicy is the Garlic Butter Steak Bites with Parmesan Cream Sauce & Cheesy Mashed Potatoes Recipe?

The dish has a mild heat from the red pepper flakes and cayenne in the blackened seasoning; you can adjust the amount to your taste or omit it entirely for a milder meal.

Can I prepare parts of this recipe ahead of time?

Yes! You can make the blackened seasoning and cheat mash earlier in the day, and sear the steak bites just before serving. The sauce is best made fresh but can be prepped a few hours in advance.

What cheese works best in the mashed potatoes?

Monterey Jack, mozzarella, or pepper jack are all fantastic choices but feel free to get creative with any melty cheese you love. Just be sure to shred it finely for smooth incorporation.
