1.5 lbs sirloin steak, cut into 1-inch cubes
4 tbsp unsalted butter, divided
4 cloves garlic, minced
1 tbsp olive oil
Salt and black pepper, to taste
Fresh parsley, chopped (for garnish)
2 lbs russet potatoes, peeled and cubed
1/2 cup whole milk, warmed
1/4 cup heavy cream
4 tbsp unsalted butter (for potatoes)
Salt and pepper, to taste (for potatoes)

directions

I start by bringing a large pot of salted water to a boil, then I add the cubed potatoes. I let them cook until fork-tender, which takes about 15 minutes.
While the potatoes are boiling, I pat the beef cubes dry using paper towels, then season them generously with salt and pepper.
In a large skillet over medium-high heat, I add the olive oil and 2 tablespoons of butter.
I place the beef cubes in a single layer, searing each side for 1–2 minutes until nicely browned. Once done, I remove the beef to a plate and cover it to keep warm.
I reduce the heat to medium, then melt the remaining 2 tablespoons of butter in the skillet and stir in the minced garlic for about 30 seconds, just until fragrant.
I return the beef to the pan and toss it in the garlic butter for a minute to coat it thoroughly, then sprinkle with chopped fresh parsley.
Once the potatoes are cooked, I drain them and return them to the pot. I add the warm milk, cream, and butter, then mash everything until smooth and creamy. I finish with salt and pepper to taste.
I serve the beef bites either on top of the mashed potatoes or alongside them, making sure to drizzle the extra garlic butter from the pan right over everything.

Variations

I sometimes swap the russet potatoes for Yukon Gold to make the mashed potatoes even richer. For a flavor twist, I like adding a splash of Worcestershire sauce to the garlic butter—it gives a deeper umami kick. If I’m feeling like spicing things up, a pinch of red pepper flakes in the butter does the trick. And when I want a veggie boost, I serve this with steamed broccoli or sautéed green beans on the side.

storage/reheating

To store leftovers, I place the beef and mashed potatoes in separate airtight containers and refrigerate for up to 3 days. When reheating, I warm the beef in a skillet over low heat to keep it tender and reheat the mashed potatoes with a splash of milk in the microwave or on the stovetop, stirring until smooth again.

FAQs

How do I keep the beef bites tender?

I make sure not to overcook them. A quick sear on high heat locks in the juices. Also, I let the beef rest before tossing it back into the pan with the garlic butter.

Can I use a different cut of beef?

Yes, I’ve used ribeye and strip steak with great results. Just make sure it’s a tender cut and slice it into even cubes.

What’s the best way to mash potatoes?

I prefer using a potato masher or a ricer for smooth and fluffy results. I also warm the milk and cream before adding to the potatoes to keep everything hot and creamy.

Can I make this recipe ahead of time?

I can make the mashed potatoes ahead and reheat them with a little milk. The beef is best cooked fresh to keep it tender, but I sometimes prep the cubes and season them ahead.

Is this recipe gluten-free?

Yes, there are no gluten-containing ingredients here. It’s naturally gluten-free and comforting, just how I like it.
