Ingredients You’ll Need

All the ingredients work together like a flavor dream team. When choosing your steak, I recommend going for ribeye or sirloin for that perfect balance of tenderness and beefy flavor. And a little heads-up — avocado oil is my go-to here because it handles the high heat beautifully without burning or smoking up your kitchen.

• Steak filet (ribeye, sirloin, etc): Choose fresh or well-marbled cuts for juicy bites.
• Avocado oil: Higher smoke point than olive oil, perfect for searing.
• Butter: Adds richness; divided use lets you layer flavor.
• Garlic cloves: Fresh garlic minced into the sauce and butter for aroma and depth.
• Heavy cream: Gives the Parmesan sauce its lush, silky texture.
• Green onions: Fresh crunch and mild onion flavor brighten the sauce.
• Red pepper flakes: Provide a subtle kick; adjust to your heat preference.
• Parmesan cheese: The star in the sauce — freshly grated works best.
• Russet potatoes: Ideal for fluffy, creamy mashed potatoes.
• Half and half: Warmed to blend smoothly into the potatoes.
• Monterey Jack cheese (or mozzarella/pepper jack): Melts beautifully for cheesy mashed potatoes.
• Garlic powder, salt, pepper: Seasonings for the potatoes and the homemade blackened seasoning.
• Smoked paprika, cayenne pepper, onion powder, thyme, oregano: Essential spices to make your own blackened seasoning — trust me, it’s worth it!

Variations

This garlic butter steak bites with Parmesan sauce recipe is a great base, but I love switching things up depending on what’s in my fridge or what kind of night I’m aiming for. Feel free to get creative!

• Spicy kick: I’ve added extra cayenne and red pepper flakes when I want a bolder heat — my family goes crazy for it that way.
• Dairy-free: Swap heavy cream for coconut cream and omit the cheese; you’ll still get a luscious sauce with a different twist.
• Different cheeses: Sometimes I use sharp cheddar or Asiago in the mashed potatoes for a punchier flavor.
• Veggie additions: Toss in sautéed mushrooms or roasted asparagus on the side to make it a full meal.

How to Make Garlic Butter Steak Bites with Parmesan Sauce Recipe

Step 1: Prep Your Steak and Potatoes Like a Pro

Start by cutting your steak into roughly 2-3 inch pieces. You want them bite-sized but not too small to keep them juicy. Rub all sides evenly with avocado oil — this helps the blackened seasoning stick and creates a perfect sear. Speaking of seasoning, I mix a homemade blackened blend with smoked paprika, cayenne, and herbs — it gives the steak an incredible depth of flavor. After seasoning, let the steak sit for about 10-15 minutes at room temperature; this trick helps it cook evenly and brings out the best texture.

Step 2: Boil Potatoes While You Cook the Steak

Peel and quarter your russet potatoes, then soak them in cold water for 10 minutes to pull out excess starch — this makes your mashed potatoes extra fluffy. Drain, then boil in salted water until fork tender, about 15 minutes. While the potatoes cook, move to your steak on the stovetop — multitasking here saves so much time!

Step 3: Sear the Steak Bites to Golden Perfection

Heat 2–3 tablespoons of avocado oil in a large skillet over medium-high heat — hot but not smoking. Add the steak pieces in a single layer without overcrowding; you might need to work in batches. Let them cook undisturbed for about 2 minutes until they develop a beautiful golden crust. Flip once and cook for another minute. Then, lower the heat and cook 1 more minute to finish. Remove the steak onto a plate and tent with foil to keep warm while you prepare the sauce. This method locks in juices — I discovered this trick after too many dry bites in the past!

Step 4: Make That Garlic Butter Magic

In the same skillet, add 3 tablespoons butter and 1 tablespoon minced garlic. Sauté until fragrant — this is where the flavor gets next-level. Toss the steak bites back in to coat in this glorious garlic butter, cooking an additional minute. Then set the steak aside again. Don’t skip this step — it really seals the deal on flavor.

Step 5: Whip Up the Creamy Parmesan Sauce

Still using the skillet with all those tasty browned bits, add 2 more tablespoons of butter and the remaining minced garlic. Sauté until fragrant, then slowly whisk in heavy cream. Let it simmer gently for 3-5 minutes so it thickens just right. Stir in red pepper flakes, diced green onions, and the grated Parmesan. As the cheese melts into the sauce, you’ll notice it becoming luxuriously smooth and thick. Taste and tweak salt and pepper — balance is everything here.

Step 6: Finish Those Cheesy Mashed Potatoes

Drain your potatoes and mash them up with melted butter and warmed half-and-half until creamy and smooth. Then fold in shredded Monterey Jack or your favorite melty cheese, garlic powder, salt, and pepper. Keep stirring until all the cheese melts into those fluffy potatoes — I find this cheesy base makes the perfect partner to the rich steak bites and sauce.

Step 7: Plate It Up and Enjoy!

To serve, spoon a generous scoop of cheesy mashed potatoes onto each plate, layer with garlic butter steak bites, and drizzle the warm Parmesan cream sauce on top. I love watching the sauce drizzle over everything — it just feels like a big, warm hug on a plate.

How to Serve Garlic Butter Steak Bites with Parmesan Sauce Recipe

Garnishes

I usually sprinkle extra chopped green onions and a pinch of fresh cracked black pepper on top — that little pop of color and freshness finishes the dish beautifully. Sometimes a light drizzle of balsamic glaze adds a sweet tang that balances the richness.

Side Dishes

Besides the cheesy mashed potatoes, try serving with simple roasted or steamed vegetables like garlic green beans, asparagus, or a crisp spinach salad dressed with lemon vinaigrette to brighten the plate.

Creative Ways to Present

For special occasions, I like to thread the steak bites onto skewers as mini kebabs, drizzle the Parmesan cream sauce in a beautiful swirl, and sprinkle with edible flowers or microgreens for a restaurant vibe. Dinner parties have never been easier or more impressive!

Make Ahead and Storage

Storing Leftovers

I store leftovers in airtight containers in the fridge up to 3 days. The steak bites stay surprisingly tender — just keep the sauce separate when possible to prevent sogginess.

Freezing

I’ve frozen portions of the steak bites and Parmesan sauce separately with great results. Just thaw overnight in the fridge to keep texture intact. Potatoes don’t freeze as well, so I usually make those fresh.

Reheating

Reheat steak bites gently in a skillet over low heat with a splash of butter or oil to avoid drying out. Warm the Parmesan sauce separately in a small saucepan over low heat, stirring to reincorporate. Microwaving works too, but go slow with low power.
