Garlic Butter Steak Potatoes

This garlic butter steak with potatoes combines tender sirloin and perfectly browned baby potatoes infused with fragrant garlic and Italian seasoning for a satisfying dinner that feels special yet comes together quickly. The balance of savory steak and buttery potatoes makes it a comforting meal you can rely on any night of the week.

I first made this when craving something hearty but easy. The family was hooked after the first bite and now I make it regularly when I want a cozy dinner with zero fuss.

Ingredients

• Sirloin steak: cut into 1-inch cubes for quick cooking and tenderness
• Low sodium soy sauce: to add umami rich depth without overpowering
• Olive oil: for searing steaks and roasting potatoes, choose extra virgin for better flavor
• Sriracha sauce: for a mild spicy kick that brightens the marinade
• Baby potatoes: that brown beautifully and cook evenly, choose firm and smooth-skinned ones
• Butter: to create the classic garlic butter richness that coats everything
• Fresh garlic: minced for a fragrant punch, fresh cloves work best over pre-minced
• Italian seasoning: blends herbs like oregano and basil to evoke classic Italian flavors
• Salt and black pepper: to season and balance out the savory richness

Step-by-Step Instructions

Sear the Potatoes:

Heat a large skillet over medium-high heat and add olive oil and butter. Place halved baby potatoes cut side down and cook without moving for about 8 minutes until golden and tender inside. This step ensures the potatoes develop a crispy crust and soften perfectly.

Sauté Garlic and Seasonings:

Remove potatoes to a plate. In the same skillet add remaining butter, minced garlic, and Italian seasoning. Cook for 30 seconds just until fragrant to bloom those herbs and garlic flavors into the butter base.

Marinate the Steak:

Combine sirloin cubes with soy sauce, olive oil, and Sriracha sauce in a bowl. Let this mixture sit while you prepare the potatoes so the flavors infuse into the meat.

Cook the Steak:

Add marinated steak cubes to the skillet in a single layer. Let them cook undisturbed for 1 minute to build a nice sear then toss and cook an additional minute for even browning. Pour the reserved marinade over the steak and cook 1 more minute to thicken the sauce slightly.

Combine and Finish:

Return the cooked potatoes to the skillet, stir everything to coat in the garlic butter sauce, and heat through for a couple of minutes. Season with salt and pepper to taste. Remove from heat and serve immediately, optionally garnished with fresh parsley or a sprinkle of Parmesan cheese.

My favorite part of this recipe is the garlic butter sauce. It magically transforms simple ingredients into a meal that feels indulgent but is surprisingly straightforward to make. Family gatherings often end with someone asking for this dish again because of that buttery garlic flavor that feels cozy and familiar.

Storage Tips

Store any leftovers in airtight containers and fridge for up to three days. For longer storage, freeze portions up to three months. To reheat, thaw frozen portions overnight and warm gently in a skillet or microwave to keep the steak tender and the potatoes crispy.

Ingredient Substitutions

• Sirloin can be swapped for ribeye or filet mignon cubes for a different texture or flavor profile but adjusting cooking time is key as fattier cuts take longer.
• If baby potatoes are unavailable, small Yukon gold or red potatoes work well. Just halve or quarter them for even cooking.
• For a spicier kick, add a dash more Sriracha or sprinkle in crushed red pepper flakes during seasoning.

Serving Suggestions

• This dish pairs perfectly with steamed green beans or a fresh arugula salad to balance richness with bright, peppery notes.
• A side of roasted vegetables like asparagus or Brussels sprouts adds complementary earthiness.
• Consider a simple crusty bread to mop up any remaining garlic butter sauce on the plate.

Frequently Asked Questions

→ How do I keep the steak tender?

Marinate the sirloin cubes in soy sauce and Sriracha to enhance flavor and tenderness. Avoid overcooking by searing each side briefly and letting the meat rest before serving.

→ What’s the best way to cook the potatoes evenly?

Use baby potatoes, halved if large, and cook them first in olive oil and butter over medium-high heat until browned and tender before adding the steak.

→ Can I substitute the sirloin with another cut?

Yes, tender cuts like ribeye or flank steak work well, but adjust cooking time to prevent toughness.

→ How does the garlic butter enhance the dish?

Garlic infused in melted butter brings a rich aroma and depth of flavor, complementing both the steak and potatoes perfectly.

→ What seasoning can I use if I don’t have Italian seasoning?

Try combining dried oregano, basil, thyme, and rosemary in equal parts as a fresh alternative for the Italian herb mix.
