How to Make Garlic Butter Steak Bites with Parmesan Cream Sauce

Let me show you how to make this incredibly delicious Garlic Butter Steak Bites meal:

Prep the Ingredients

1. I cut the steak into 2-3″ pieces.
2. I rub them evenly with avocado oil, then season well on all sides with the homemade blackened seasoning. I let the steak sit for 10-15 minutes at room temp to remove the chill from the fridge while preparing the potatoes.
3. I peel the potatoes and quarter them. I place them in a bowl of cold water for 10 minutes to remove the excess starch.
4. I drain, then place them in a pot of salted water and boil them until fork-tender while I cook steak.

Cook Steak

1. In a large skillet over medium-high heat, I heat 2-3 tablespoons of avocado oil.
2. I add the steak pieces to the hot skillet (I may need to cook in batches to avoid overcrowding).
3. I cook them undisturbed for about 2 minutes, or until they have a good golden coloring.
4. I flip just once. I continue to cook for 1 minute, then reduce the heat to low and cook for 1 minute more.
5. I remove the steak and place it in a bowl.

Make Garlic Butter and Toss Steak

1. I add 3 tablespoons of butter and 1 tablespoon of the minced garlic to the same pan and sauté in the butter until fragrant.
2. I toss the steak in the garlic butter, coating all sides, and cook for another minute.
3. I remove the steak and place it in a bowl, tented with foil to keep it moist.

Make the Parmesan Cream Sauce

1. In the same pan with the residual butter and garlic, I add two more tablespoons of butter and the remaining minced garlic. I sauté until fragrant.
2. Slowly, I whisk in the heavy cream and bring it to a simmer, allowing it to reduce for 3-5 minutes.

Make Cheesy Mashed Potatoes

1. Meanwhile, I drain the water from the boiled potatoes.
2. I add the melted butter and warmed half-and-half and mash until no longer chunky.
3. I add the shredded Monterey Jack cheese, garlic powder, salt, and pepper, and mix until smooth.

Finish the Cream Sauce and Serve

1. Into the simmering cream sauce, I add the red pepper flakes and diced green onions.
2. Then I add the Parmesan cheese. I whisk until the sauce thickens.
3. I taste and adjust salt and pepper.
4. Serve steak over potatoes and sauce.

Tips and Tricks for the BEST Steak Bites

Here are my secrets for making this dish truly exceptional:

• Use Good Quality Steak: The quality of the steak makes a difference. Choose a cut known for tenderness like filet, ribeye, or sirloin.
• Hot Pan for Searing: Ensure the skillet is hot before adding the steak to get a good sear.
• Don’t Overcook: Cook the steak bites quickly to keep them tender. Use a meat thermometer if needed (aim for your preferred internal temperature, keeping carryover cooking in mind).
• Freshly Grated Parmesan: This melts better and has superior flavor compared to pre-shredded.
• Warm the Cream/Milk for Potatoes: Warming the half-and-half before adding it to the potatoes helps create a smoother mash.

How to Serve

This Garlic Butter Steak Bites with Parmesan Cream Sauce is a rich meal best served:

• Over Cheesy Mashed Potatoes: As described in the recipe, this is the ultimate comfort food pairing.
• Over Pasta: Fettuccine or pappardelle would be excellent choices.
• With Roasted Vegetables: Balance the richness with a side of roasted asparagus, broccoli, or Brussels sprouts.
• With Crusty Bread: For soaking up every last bit of the delicious sauce.

Make Ahead and Storage

You can make the mashed potatoes and the Parmesan cream sauce ahead of time. Store them separately in the refrigerator. Reheat gently before serving. The steak bites are best cooked just before serving. Leftovers can be stored in the refrigerator for up to 2 days.

FAQs about Garlic Butter Steak Bites with Parmesan Cream Sauce

Instructions

 Prepare Potatoes:

• Peel and quarter the russet potatoes. Place them in a large bowl of cold water for about 10 minutes to remove excess starch. Drain well.
• Place the drained potatoes in a large pot, cover with cold salted water, and bring to a boil. Cook until fork-tender (about 15-20 minutes).

2. Prepare Steak:

• While potatoes are cooking, cut the steak into 2-3 inch pieces. Pat the steak pieces dry with paper towels.
• Rub the steak pieces evenly with 1-2 tablespoons of avocado oil.
• Season the steak generously on all sides with the blackened seasoning.
• Let the seasoned steak sit at room temperature for 10-15 minutes while the potatoes finish cooking.

3. Cook Steak Bites:

• Heat 2-3 tablespoons of avocado oil in a large skillet (cast iron recommended) over medium-high heat.
• Once the oil is hot and shimmering, add the steak pieces to the skillet in a single layer. Do not overcrowd the pan; cook in batches if necessary.
• Cook undisturbed for about 2 minutes, or until a good golden-brown sear forms on the bottom.
• Flip the steak pieces just once. Continue to cook for 1 minute on the second side.
• Reduce the heat to low and cook for another 1 minute (for medium-rare, adjust time for desired doneness).
• Remove the steak pieces from the skillet and place them in a bowl.
• Add 3 tablespoons of unsalted butter and 1 tablespoon of minced garlic to the same skillet. Sauté for about 30 seconds until fragrant.
• Return the steak pieces to the skillet and toss them in the garlic butter to coat on all sides, cooking for another minute.
• Remove the steak bites from the skillet again and place them back in the bowl. Tent loosely with foil to keep warm.

4. Finish Mashed Potatoes:

• Drain the cooked potatoes thoroughly. Return them to the pot (off the heat).
• Add the warmed half-and-half and melted salted butter. Mash the potatoes until no longer chunky (use a potato masher or ricer).
• Add the shredded Monterey Jack cheese, garlic powder, salt, and pepper. Stir until the cheese is melted and the potatoes are smooth and creamy. Keep warm.

5. Make Parmesan Cream Sauce:

• In the same skillet used for the steak (with residual butter and garlic), melt the remaining 2 tablespoons of unsalted butter over medium heat.
• Add the remaining 9 cloves of minced garlic and sauté until fragrant, about 30-60 seconds.
• Slowly whisk in the heavy cream. Bring the mixture to a gentle simmer. Allow it to reduce and thicken slightly, about 3-5 minutes, stirring occasionally.
• Stir in the diced green onions and red pepper flakes.
• Reduce heat to low. Gradually stir in the grated Parmesan cheese until melted and the sauce is smooth. Do not let the sauce boil vigorously after adding cheese.
• Taste the sauce and adjust salt and pepper as needed.

6. Serve:

• Spoon a generous portion of the cheesy mashed potatoes onto each plate.
• Top the potatoes with the garlic butter steak bites.
• Spoon the Parmesan cream sauce generously over the steak and potatoes. Serve immediately.

Notes

• Steak: Choose a tender cut like filet mignon, ribeye, or sirloin for best results. Cut into uniform pieces for even cooking.
• Blackened Seasoning: Adjust the cayenne in the homemade blend or use less store-bought seasoning if you prefer less heat.
• Potatoes: Russet potatoes create fluffy mashed potatoes. Yukon Golds can also be used for a creamier texture.
• Cheese: Freshly grated Parmesan melts best in the sauce. Feel free to swap the Monterey Jack in the potatoes for other melty cheeses.
• Cooking Steak: Adjust cooking time for desired doneness (rare, medium, well-done). Using an instant-read thermometer is recommended.
• Sauce Consistency: If the sauce is too thick, thin it with a little extra heavy cream or chicken broth.
• Storage: Store leftover components separately in airtight containers in the refrigerator. Reheat gently.
