Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the Steak Bites:

• 1 ½ lbs sirloin steak, cut into bite-sized pieces
• 4 cloves garlic, minced
• 4 tablespoons unsalted butter
• 2 tablespoons olive oil
• Salt and pepper, to taste
• Fresh parsley, chopped, for garnish

For the Mashed Potatoes:

• 2 lbs russet potatoes, peeled and cut into chunks
• ½ cup whole milk
• 4 tablespoons unsalted butter
• ¼ cup sour cream
• Salt and pepper, to taste

Directions

Step 1: Make the Mashed Potatoes
I start by boiling the potato chunks in a large pot of salted water until they’re fork-tender—usually about 15–20 minutes. After draining, I return them to the pot and mash them with milk, butter, and sour cream until smooth and fluffy. I season to taste with salt and pepper and keep them warm while preparing the steak.

Step 2: Sear the Steak Bites
Next, I heat olive oil in a large skillet over medium-high heat. I season the steak pieces with salt and pepper, then add them to the pan in a single layer (working in batches if necessary). I let each side cook for 2–3 minutes until browned and juicy, then remove them from the pan and set them aside.

Step 3: Make the Garlic Butter Sauce
With the skillet still hot, I lower the heat to medium and melt the butter. I add the minced garlic and stir constantly for about 1–2 minutes, just until fragrant—being careful not to let it brown too much.

Step 4: Finish and Serve
I return the steak bites to the skillet and toss them in the garlic butter until fully coated. A quick minute of warming through and they’re ready. I spoon the steak bites over a generous helping of mashed potatoes and finish with a sprinkle of fresh parsley.

Variations

• Make It Creamier: I sometimes add a splash of cream cheese or extra sour cream to the potatoes for an ultra-smooth texture.
• Add Veggies: Roasted broccoli or green beans pair perfectly here.
• Spicy Twist: A pinch of crushed red pepper in the garlic butter gives the steak bites a mild kick.
• Change the Cut: If I don’t have sirloin, I use ribeye or strip steak—whatever’s on hand.

Storage/Reheating

Storage: I store any leftovers in an airtight container in the fridge for up to 3 days.
Reheating: I reheat the steak bites gently in a skillet with a little butter to keep them juicy. Mashed potatoes go back in the microwave or stovetop with a splash of milk to bring them back to life.

FAQs

Can I use a different cut of beef?

Absolutely. I sometimes use ribeye or New York strip for extra tenderness and marbling.

What’s the best way to avoid overcooking the steak bites?

I cook them in batches over high heat and avoid crowding the pan. That way, each piece gets a good sear without steaming.

Can I prep this ahead of time?

Yes, I often prep the potatoes ahead and reheat them. The steak bites are best fresh, but they reheat well if done gently.

Is there a substitute for sour cream in the mashed potatoes?

Greek yogurt or cream cheese both work well for a tangy, creamy texture.

What sides go well with this dish?

Steamed veggies, garlic bread, or a crisp side salad all pair beautifully.
