Ingredients You’ll Need

I love how these ingredients come together to create a steak dinner that balances rich, creamy sauce with perfectly seared steak bites. Plus, the homemade blackened seasoning is a game-changer that brings some smoky, spicy depth you won’t find in store-bought blends.

• Steak filet (ribeye, sirloin, etc): Choose good quality cuts – they’ll sear beautifully and stay tender.
• Avocado oil: I prefer this for searing because it has a higher smoke point than olive oil, so no burnt flavors here.
• Butter: Divided for cooking steak and making the rich sauce; salted butter adds great flavor depth.
• Garlic: Fresh minced garlic is key here to get that aromatic punch in both the steak and sauce.
• Heavy cream: Bring the sauce together with luxurious creaminess.
• Green onions: Adds a fresh, mild onion pop and bright color.
• Red pepper flakes: For just a little kick—adjust to your heat preference.
• Parmesan cheese: Use freshly grated or shaved for the best melt and flavor.
• Russet potatoes: For creamy, cheesy mashed potatoes – they absorb butter and cream beautifully.
• Half and half: Warmed before mashing for a smoother, creamier texture.
• Monterey Jack or preferred cheese: Adds extra melty goodness to those mashed potatoes.
• Garlic powder, salt, pepper: Essential seasonings for mashed potatoes and blackened rub.
• Homemade blackened seasoning spices: Smoked paprika, cayenne, onion powder, black pepper, thyme, oregano—all combined to pack a flavorful punch.

Variations

Over time, I’ve tweaked this Garlic Butter Steak Bites with Parmesan Sauce Recipe based on what’s in my kitchen or to suit different tastes, and I always encourage you to make it your own. Maybe you want less heat, more herbs, or a cheese swap—go for it!

• Milder Version: You can reduce or skip the red pepper flakes if you’re not into spicy food; the sauce is still deliciously creamy.
• Herb-Infused: Adding fresh rosemary or thyme to the skillet while cooking the steak adds a lovely aromatic touch.
• Cheese Options: Feel free to swap Monterey Jack for mozzarella, pepper jack, or any melting cheese you love in the mashed potatoes.
• Low Carb: Skip the mashed potatoes and serve steak bites and sauce over steamed veggies or cauliflower mash for a keto-friendly meal.

How to Make Garlic Butter Steak Bites with Parmesan Sauce Recipe

Step 1: Prep Your Steak and Potatoes

Start by cutting your steak into 2 to 3-inch chunks—this size allows for a perfectly seared crust with a tender inside. Rub the steak evenly with avocado oil; this helps the blackened seasoning stick while also preventing sticking to the pan. Make sure to season generously with the homemade blackened seasoning on all sides. Once seasoned, let the steak rest at room temperature for about 10-15 minutes. This step is crucial because it takes the chill off the meat, which means better searing and juicier bites.

While the steak is resting, peel and quarter your potatoes. To slam dunk the creamiest mashed potatoes, soak them in cold water for 10 minutes—that pulls excess starch and prevents gluey results. After soaking, drain, rinse, and place the potatoes into a pot with salted water and bring to a boil. Leave them cooking until fork-tender while you start on your steak. Multitasking for the win!

Step 2: Sear the Steak Bites to Golden Perfection

Heat a large skillet over medium-high heat and pour in 2-3 tablespoons of avocado oil. When the oil is shimmering hot, add the steak bites in a single layer—don’t overcrowd the pan or they’ll steam instead of sear. You might need to cook in batches, but trust me, it’s worth it for that gorgeous brown crust. Let them cook undisturbed for about 2 minutes until you see a beautiful golden color developing. Flip them once, cook for an additional minute, then immediately reduce the heat to low and give them one more minute to finish cooking gently. This method keeps the steak juicy while achieving that charred flavor I love.

Remove the steak from the skillet and set aside in a bowl. Now, toss in 3 tablespoons of butter and 1 tablespoon of minced garlic right into the same pan. Sauté the garlic until fragrant (about 30 seconds) and return the steak bites to the skillet. Toss them around to coat thoroughly with the garlic butter, letting the flavors soak in for another minute. Then pop them back in a bowl and tent with foil so they stay warm and succulent.

Step 3: Whip Up the Dreamy Parmesan Cream Sauce & Finish Mashed Potatoes

With the steak bites resting, use the same skillet (don’t wash it – those yummy browned bits hold flavor!) and add the remaining 2 tablespoons of butter and all the rest of your minced garlic. Sauté until aromatic, then slowly whisk in the heavy cream, scraping the pan to deglaze it. Let the cream come to a gentle simmer and reduce for about 3-5 minutes. This step thickens the sauce and gives it that irresistible velvety texture.

Meanwhile, drain your cooked potatoes and transfer to a bowl. Add warmed half and half, melted butter, garlic powder, salt, pepper, and your choice of shredded cheese. Mash until creamy but still a bit chunky for texture and a comforting feel. Finally, stir in the red pepper flakes, scallions, and Parmesan cheese into the cream sauce—whisk until you see it thicken up nicely. Taste and adjust seasoning; this sauce is the crown jewel of the dish!

To serve, plate a generous scoop of cheesy mashed potatoes, arrange the garlic butter steak bites over top, and drizzle with that luscious Parmesan cream sauce. It’s show-stopping but surprisingly easy.

How to Serve Garlic Butter Steak Bites with Parmesan Sauce Recipe

Garnishes

I usually finish this dish with a sprinkle of extra fresh green onions and sometimes a little chopped parsley for a burst of color and freshness. Those red pepper flakes in the sauce add just the right touch of heat, but if you want, a few freshly cracked black peppercorns on top give a subtle crunch and aromatic boost.

Side Dishes

While cheesy mashed potatoes are the classic and my top pick for this recipe, I’ve also served it with garlic roasted asparagus, steamed green beans, or even a crisp Caesar salad for a lighter contrast. You’ll find the creamy sauce pairs well with greens that are a bit bitter or crisp to balance the richness.

Creative Ways to Present

For special occasions, I like to plate the steak bites on a bed of mashed potatoes in a shallow bowl, drizzle the Parmesan sauce artfully over top, and add edible flowers or microgreens for a fancy touch. Bringing that steakhouse vibe home makes the dinner feel extra special without additional effort.

Make Ahead and Storage

Storing Leftovers

I store leftover steak bites and sauce in an airtight container in the fridge for up to 3 days. Separating the mashed potatoes in another container helps keep flavors fresh and textures on point. Just make sure everything cools down before refrigerating.

Freezing

Freezing the steak bites and sauce is possible but I’ve noticed the texture of the mashed potatoes changes a bit when frozen, becoming a little grainy. If you want to freeze, do it without the potatoes and reheat together with freshly made or reheated mash later.

Reheating

Reheat the steak bites gently in a skillet over low heat to avoid drying out, adding a splash of butter or a little cream if the sauce thickened too much. For mashed potatoes, warming in the microwave with a small pat of butter or in a small pan with some cream restores creaminess nicely.
