Garlic Butter Steak Bites with Creamy Parmesan Mashed Potatoes Tips, FAQ & printable recipe

Tips for success

To achieve an even more intense garlic flavor, you can toast the minced garlic in the butter for a few seconds before adding the steak back to the pan.

If you prefer a lighter potato texture, you can add a splash of warm milk or heavy cream while mashing, though the butter and parmesan usually provide enough richness to keep the texture luxurious and smooth.

When adding the steak back to the skillet, ensure you do it in the final stages of the process to avoid overcooking. The residual heat of the pan and the butter sauce will continue to cook the meat slightly, so pulling the steak at the correct temperature before the final toss is key to maintaining the perfect level of doneness.

Variations

• Spicy Garlic Steak Bites: Add a teaspoon of red pepper flakes to the butter sauce along with the garlic to introduce a subtle heat that cuts through the richness of the beef.
• Herb-Infused Potatoes: Stir in fresh chives or rosemary into the mashed potatoes during the final mashing stage to add a fragrant, earthy note that complements the garlic butter.

Storage and make-ahead

Fridge

Keep in an airtight container for up to 3 days.

Freezer

Not recommended, as the texture of the potatoes and steak will degrade significantly upon thawing.

Reheat

Reheat gently in a skillet over low heat with a teaspoon of water or butter to loosen the sauce until warmed through.

Store any leftovers in an airtight container to prevent the steak from drying out. Keep the potatoes and steak together if possible, as the sauce will continue to season the potatoes. Consume within 3 days for the best quality. Ensure the food cools to room temperature for no more than 2 hours before placing it in the refrigerator.

You can prepare the mashed potatoes in advance and reheat them gently on the stove with a splash of milk. The steak, however, is best cooked fresh immediately before serving, as reheating steak often leads to a tougher texture.

You can cut and season the steak ahead of time, keeping it in the refrigerator until you are ready to sear.

Serving ideas

Serve this dish immediately on pre-warmed plates to keep the butter sauce from solidifying. Spoon a generous amount of the creamy parmesan mashed potatoes onto the center of the plate, then top with the glistening garlic butter steak bites.

Drizzle any remaining sauce from the skillet over the top of the steak and potatoes for an extra hit of flavor.

For a complete meal, serve alongside steamed green beans or a simple arugula salad with a light lemon vinaigrette.

The brightness of the green vegetables or the acidity of the salad cuts through the richness of the steak and potatoes, providing a balanced and satisfying dining experience. Ensure every plate gets a generous portion of the garlic butter from the pan.

Ingredients

• 2 lbs Yukon Gold potatoes, peeled and quartered

• 1/2 cup grated parmesan cheese
• 1 1/2 lbs sirloin steak, cut into 1-inch cubes
• 4 cloves garlic, minced
• 3 tbsp unsalted butter

Instructions

1. Place the peeled and quartered potatoes in a large pot of salted water. Bring to a boil and cook until fork-tender, about 15 minutes. Drain the water, then add the butter and parmesan cheese. Mash until smooth and creamy. Keep warm while preparing the steak.
2. Heat a heavy cast iron skillet over high heat. Pat the steak cubes dry and season with salt and pepper. Add to the hot skillet in a single layer.
