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

Tips for success

To take your mashed potatoes to the next level of silkiness, pass the boiled potatoes through a potato ricer or food mill instead of using a traditional hand masher. This technique breaks down the potatoes evenly without overworking the starches, resulting in an incredibly light, cloud-like texture.

When adding the butter, make sure it is warm or at least at room temperature. Cold dairy cools down the hot potatoes too quickly, preventing them from fully absorbing the fats and leading to a heavy, dense texture.

For the absolute best sear on your steak bites, use a well-seasoned cast-iron skillet or a heavy stainless steel pan. These pans retain heat exceptionally well, which is crucial for maintaining high temperatures when the cold meat is added.

Avoid using non-stick pans, as they cannot safely reach the high temperatures required to create a deep, caramelized crust. Let the pan heat up for a few minutes before adding the steak, and ensure the skillet is extremely hot before dropping in the beef.

Variations

• Herbed Garlic Butter: Stir fresh chopped rosemary or thyme into the melting butter along with the garlic for an earthy, aromatic twist on the classic sauce.
• Loaded Parmesan Mash: Fold crispy cooked bacon bits and chopped chives into the whipped potatoes along with the parmesan cheese for extra texture and flavor.

Storage and make-ahead

Fridge

Cool leftovers for no more than 2 hours, then store in airtight containers in the refrigerator for up to 3 to 4 days.

Freezer

Freeze the mashed potatoes in a freezer-safe container for up to 1 month. Freezing the cooked steak bites is not recommended.

Reheat

Reheat potatoes on the stovetop over low heat with a splash of melted butter. Reheat steak bites quickly in a hot skillet with butter.

Store any leftover steak bites and mashed potatoes in separate airtight containers in the refrigerator within 2 hours of cooking to ensure food safety. Keeping them separate prevents the potatoes from absorbing too much of the butter sauce and becoming soggy, while allowing you to reheat each component perfectly. When stored correctly, the leftovers will remain fresh and delicious for up to 3 to 4 days.

While the steak bites are best enjoyed fresh from the skillet, you can easily prepare the creamy parmesan mashed potatoes up to 24 hours in advance. Store the cooked potatoes in an airtight container in the refrigerator.

When ready to serve, gently reheat them on the stovetop over low heat, stirring in an extra spoonful of warm butter to restore their smooth, velvety texture. The steak bites should always be cooked right before serving to maintain their tender texture.

Serving ideas

Serve this comforting dish by creating a generous well of creamy parmesan mashed potatoes in the center of a warm, shallow bowl or plate. Spoon the hot, tender steak bites directly into the center of the potato well, allowing them to nestle into the fluffy mash. Pour the rich, fragrant garlic butter sauce from the skillet generously over both the steak and the potatoes, letting the golden butter pool in the crevices of the potatoes for an elegant presentation.

To complement the rich, savory flavors of the garlic butter beef and cheesy potatoes, serve this meal alongside a crisp, bright green salad dressed with a simple lemon vinaigrette. The acidity of the salad cuts through the richness of the butter and cheese, refreshing the palate between bites.

Roasted green vegetables, such as asparagus spears, green beans, or tender broccoli florets, also make excellent side dishes that pair beautifully with the steakhouse-style theme of the meal.

Garlic Butter Steak Bites with Creamy Parmesan Mashed Potatoes

Prep 15 minCook 20 minRest 3 minTotal 38 minServes 4

Ingredients

• 2 lb Yukon Gold potatoes, peeled and cubed
• 3/4 cup unsalted butter, divided
• 1/2 cup grated parmesan cheese
• 1 1/2 lb sirloin steak, cut into 1-inch cubes
• 4 cloves garlic, minced

Instructions

1. Place the peeled and cubed Yukon Gold potatoes in a large pot. Cover them with cold water and bring to a boil over high heat. Cook the potatoes until they are completely fork-tender, which should take about 15 minutes, then drain them thoroughly in a colander.
2. Return the drained hot potatoes to the pot. Add half of the unsalted butter and the grated parmesan cheese. Mash or whip the ingredients together until the mixture is completely smooth, fluffy, and free of lumps, then cover and keep warm.
3. Pat the cubed sirloin steak dry with paper towels. Heat a large cast-iron skillet over high heat until it is shimmering and extremely hot. Add the steak bites in a single layer and sear without moving for 2 minutes to form a deep golden-brown crust, then toss and cook for another 1 to 2 minutes.
4. Reduce the heat to medium-low. Add the remaining unsalted butter and the minced garlic to the skillet. Toss the steak bites continuously in the melting butter for about 1 minute, ensuring the garlic becomes fragrant without browning. Confirm the steak reaches an internal temperature of 145°F (63°C) and let the meat rest for 3 minutes. Serve the warm steak bites over the whipped parmesan potatoes, drizzling the rich garlic butter sauce from the pan over the top.
