Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Steak Bites:

1.5 lb sirloin steak, cut into bite-sized cubes

Salt and black pepper, to taste

1 tablespoon olive oil

3 tablespoons unsalted butter

5 cloves garlic, minced

1 tablespoon fresh parsley, chopped (plus more for garnish)

1 teaspoon smoked paprika (optional)

For the Mashed Potatoes:

2 lb Yukon Gold or Russet potatoes, peeled and cubed

4 tablespoons unsalted butter

1/2 cup whole milk or heavy cream (more as needed)

Salt and pepper, to taste

Directions

I bring a large pot of salted water to a boil. Then I add the potatoes and cook them for 15 to 20 minutes, until they’re fork-tender. After draining them well, I mash them with butter and milk until they’re smooth and creamy. I season them with salt and pepper, then cover and keep them warm.

While the potatoes are cooking, I pat the steak cubes dry and season them generously with salt, pepper, and smoked paprika (if I’m using it).

I heat olive oil in a large skillet over medium-high heat. I add the steak in a single layer and sear it undisturbed for 2 to 3 minutes, then flip and cook for another 2 to 3 minutes until browned but still juicy. If needed, I work in batches to avoid overcrowding.

I reduce the heat to medium, add butter and garlic to the skillet, and stir to coat the steak bites in the garlic butter. I cook for another 1 to 2 minutes, being careful not to burn the garlic.

I sprinkle chopped parsley over the steak bites and remove the skillet from heat.

I serve the hot steak bites over a bed of mashed potatoes and garnish with more parsley if I want an extra pop of color and flavor.

Servings and timing

This recipe makes 4 servings. It takes about 15 minutes to prep and 25 minutes to cook, bringing the total time to 40 minutes.

Variations

I sometimes swap the sirloin with ribeye or tenderloin for an even more tender bite.

For a low-carb version, I serve the steak bites over cauliflower mash instead of potatoes.

A splash of lemon juice or a dash of Worcestershire sauce adds a new layer of flavor to the garlic butter.

I like adding a pinch of chili flakes to the garlic butter when I want a little heat.

Swapping parsley for thyme or rosemary gives it a more herbaceous twist.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 3 days. To reheat, I warm the steak bites in a skillet over medium heat until heated through, and I reheat the mashed potatoes with a splash of milk to bring back their creamy texture. I avoid microwaving the steak to keep it from becoming tough.

FAQs

How do I keep the steak bites from overcooking?

I make sure the pan is hot before adding the steak and cook them quickly in batches. I also avoid overcrowding the pan to ensure a good sear without steaming the meat.

Can I make the mashed potatoes ahead of time?

Yes, I often make them a day ahead and store them in the fridge. When ready to serve, I reheat with a bit of milk and butter until smooth again.

What cut of steak works best for this recipe?

I usually use sirloin for a good balance of tenderness and flavor, but ribeye or tenderloin also work great if I want something extra rich.

Can I freeze the leftovers?

I don’t recommend freezing the mashed potatoes as they can change texture, but the steak bites freeze well. I reheat them gently in a pan to keep them juicy.

What can I serve with this dish besides mashed potatoes?

When I want something lighter, I serve the steak bites with steamed veggies, a crisp green salad, or roasted cauliflower.
