Why You’ll Love This Recipe

I appreciate how this recipe delivers restaurant-style flavor with simple ingredients and straightforward cooking techniques. The steak develops a delicious crust while staying tender and juicy inside, and the mushroom mash adds a creamy and flavorful twist to classic mashed potatoes.

Ingredients

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

For the steak:

beef steaks
olive oil
butter
garlic cloves
fresh thyme or rosemary
salt
black pepper

For the mushroom mash:

potatoes, peeled and chopped
mushrooms, sliced
butter
heavy cream or milk
garlic cloves, minced
parmesan cheese, optional
salt
black pepper
fresh parsley

Directions

I start by boiling the potatoes in salted water until fork-tender, then I drain them and set them aside.
While the potatoes cook, I sauté the mushrooms in butter over medium heat until golden brown and tender.
I add the minced garlic to the mushrooms and cook for another minute until fragrant.
I mash the cooked potatoes with butter and cream until smooth, then fold in the sautéed mushrooms and parmesan cheese if using.
I season the mushroom mash with salt and black pepper and keep it warm.
I pat the steaks dry and season both sides generously with salt and black pepper.
In a hot skillet, I heat olive oil and sear the steaks for several minutes on each side until cooked to my preferred doneness.
I add butter, garlic cloves, and fresh herbs to the skillet and spoon the melted butter over the steaks for extra flavor.
I let the steaks rest for a few minutes before serving them over the mushroom mash.
I finish the dish with fresh parsley and extra black pepper if desired.

Variations

I sometimes use sweet potatoes instead of regular potatoes for a slightly sweeter mash. When I want extra richness, I stir cream cheese into the mashed potatoes. I also enjoy adding caramelized onions alongside the mushrooms for deeper flavor. For a more luxurious version, I occasionally top the steak with a creamy mushroom sauce. If I want extra greens, I serve the dish with sautéed spinach or roasted asparagus.

storage/reheating

I store leftover steak and mushroom mash separately in airtight containers in the refrigerator for up to 3 days. When reheating the steak, I warm it gently in a skillet over low heat to avoid overcooking. I reheat the mash on the stovetop or in the microwave with a splash of cream or milk to keep it smooth and creamy.

FAQs

What cut of steak works best for this recipe?

I enjoy using ribeye, sirloin, or New York strip because they stay tender and flavorful when seared.

Can I make the mushroom mash ahead of time?

I often prepare the mash ahead and reheat it gently before serving.

How do I know when the steak is done?

I use a meat thermometer or check the firmness of the steak depending on my preferred doneness.

Can I use different mushrooms?

I like using cremini, button, or portobello mushrooms depending on the flavor and texture I want.
