How to Make Steak with Creamy Mushroom Sauce
Pat the steak dry with paper towels. Season generously on both sides with salt and freshly ground black pepper. Heat olive oil in a heavy skillet over medium high heat until shimmering. Place the steak in the pan and let it sear undisturbed for 3 to 4 minutes until a deep golden crust forms.
Reduce the heat slightly. Add butter and fresh thyme to the pan. As the butter melts and begins to foam, tilt the skillet and spoon the melted butter over the steak repeatedly. This builds flavor and keeps the meat juicy.
Add crushed garlic cloves to the pan. Continue basting for another 1 to 2 minutes until the steak reaches your desired doneness. Remove from the skillet and let it rest for at least 5 minutes to lock in the juices.
In the same skillet, add sliced mushrooms. Cook over medium heat without stirring too often. Allow them to release their moisture and caramelize properly. This step creates deep savory flavor for the sauce.
Pour in heavy cream along with a splash of water if needed. Add Dijon mustard and Worcestershire sauce. Stir gently and bring to a low simmer. The sauce will begin to thicken as it cooks.
Let the sauce simmer gently for 4 to 6 minutes until smooth and velvety. Stir occasionally. Taste and adjust seasoning with salt and pepper. The sauce should coat the back of a spoon.
Slice the rested steak against the grain. Spoon the creamy mushroom sauce generously over the top. Serve immediately with mashed potatoes and your favorite vegetables for a complete and satisfying meal.

Frequently Asked Questions
What is the best cut of steak for this recipe?
Ribeye is ideal for its marbling and rich flavor. Sirloin is a leaner option that still stays tender when cooked properly. Choose steaks about 1 inch thick for best results.
What temperature should steak be cooked to?
For medium rare, cook to 130–135°F. For medium, aim for 135–145°F. Always let the steak rest for 5 minutes before slicing to retain juices.
Can the mushroom sauce be made ahead?
Yes. Prepare the sauce up to 2 days in advance. Store refrigerated and reheat gently over low heat. Add a small splash of cream if needed to adjust consistency.
How do I thicken the cream sauce properly?
Simmer the sauce uncovered until it reduces naturally. Avoid high heat, which can cause the cream to separate.
What sides pair best with steak and mushroom sauce?
Mashed potatoes are the classic choice. Roasted vegetables, steamed broccoli, or buttered rice also complement the rich sauce well.
