Ingredients
For the steak
2 pounds beef tenderloin or your favorite steak cut
2 tablespoons olive oil
3 tablespoons butter
4 cloves garlic, minced
1 teaspoon salt
1 teaspoon freshly ground black pepper
1 teaspoon dried Italian seasoning
1 teaspoon fresh thyme leaves
For the creamy mushroom sauce
12 ounces mushrooms, sliced
2 tablespoons butter
3 cloves garlic, minced
1 small onion, finely chopped
1 cup heavy cream
1/2 cup beef broth
1 teaspoon Worcestershire sauce
1/2 teaspoon Italian seasoning
1 teaspoon fresh thyme
Salt and black pepper to taste
2 tablespoons grated Parmesan cheese, optional
Fresh parsley or thyme for garnish
Instructions
Prepare the steak
Take the steaks out of the refrigerator about 20 to 30 minutes before cooking. Allowing them to come closer to room temperature helps them cook more evenly.
Pat the steaks completely dry with paper towels. Season both sides generously with salt, black pepper, and Italian seasoning.
Sear the steak
Heat a large heavy skillet over medium high heat. Add the olive oil and allow it to become hot.
Place the steaks in the pan and sear without moving them for about 3 to 4 minutes, depending on their thickness.
Flip the steaks and cook the other side for another 3 to 4 minutes.
Add the butter, minced garlic, and fresh thyme to the skillet. As the butter melts, spoon the garlic butter repeatedly over the steaks.
Continue cooking until the steaks reach your preferred level of doneness.
For the best results, use a meat thermometer. The exact cooking time will depend on the thickness of the steak and your desired doneness.
Transfer the steaks to a plate and loosely cover them with foil. Let them rest for at least 5 to 10 minutes before slicing.
Make the mushroom sauce
Keep the same skillet over medium heat. Add the butter and sliced mushrooms.
Cook the mushrooms for several minutes, stirring occasionally, until they become golden brown and release their moisture.
Add the chopped onion and cook until softened.
Stir in the minced garlic and cook for about 30 seconds, just until fragrant.
Pour in the beef broth and Worcestershire sauce. Scrape the bottom of the skillet with a wooden spoon to release all the flavorful browned bits left from the steak.
Let the mixture simmer for a few minutes.
Reduce the heat to medium low and pour in the heavy cream. Add the Italian seasoning and fresh thyme.
Stir gently and allow the sauce to simmer until it becomes creamy and slightly thickened.
If using Parmesan cheese, stir it in at this stage and let it melt into the sauce.
Taste and adjust the seasoning with salt and freshly ground black pepper.
Slice and serve
After the steak has rested, slice it into thick pieces against the grain.
Arrange the sliced steak over the creamy mushroom sauce and garnish with fresh thyme or parsley.
Spoon some of the sauce and mushrooms over the steak before serving.
Tips for the Best Steak
Always pat the steak dry before seasoning. A dry surface helps create a better sear.
Do not overcrowd the skillet. If necessary, cook the steaks in batches.
Let the pan become properly hot before adding the steak.
Avoid constantly flipping the meat. Let it develop a deep golden brown crust before turning.
Resting the steak is important because it allows the juices to redistribute throughout the meat.
For the mushroom sauce, allow the mushrooms to brown properly before adding the cream. This gives the sauce much more flavor.
What to Serve With It
This steak pairs beautifully with creamy mashed potatoes, roasted potatoes, steamed vegetables, green beans, asparagus, rice, or a simple green salad.
Crusty bread is also perfect for soaking up every bit of the creamy mushroom sauce.
Storage and Reheating
Store leftover steak and mushroom sauce separately in airtight containers in the refrigerator for up to 3 days.
Reheat the mushroom sauce gently over low heat. Warm the steak carefully so it does not become overcooked and dry.
Final Thoughts
This Garlic Butter Steak with Creamy Mushroom Sauce is perfect for a cozy weekend dinner, date night at home, or whenever you want to turn an ordinary meal into something special.
The juicy steak, golden mushrooms, garlic butter, and creamy sauce make this a recipe worth coming back to again and again.
