Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 strip steaks, 8 ounces each
1 teaspoon kosher salt
1/2 teaspoon black pepper
2 tablespoons salted butter
2 tablespoons olive oil
1 small red onion, finely diced
3 garlic cloves, thinly sliced
1 teaspoon fresh thyme leaves
1/2 cup beef broth
1 cup heavy cream
1 tablespoon whole-grain mustard
1 tablespoon balsamic reduction
3 tablespoons fresh chives, minced
Directions
Remove the steaks from the refrigerator about 30 minutes before cooking. Allowing the meat to sit at room temperature helps it cook evenly and creates a better sear.
Season both sides of the steaks evenly with kosher salt and black pepper.
Heat a large heavy-bottomed skillet over medium-high heat. Add the butter and olive oil, allowing the butter to melt completely.
Place the steaks into the hot skillet and cook for approximately 3 minutes on the first side without moving them. Flip and cook another 3 minutes for medium-rare, or continue cooking until your desired doneness is reached.
Transfer the steaks to a cutting board and let them rest while preparing the sauce.
In the same skillet, add the diced onion, sliced garlic, and thyme leaves. Cook for 2 to 3 minutes, stirring frequently, until softened and fragrant.
Pour in the beef broth and scrape the bottom of the skillet with a wooden spoon to release all the flavorful browned bits.
Stir in the heavy cream, whole-grain mustard, and balsamic reduction. Let the sauce simmer gently for about 2 minutes until smooth and slightly thickened.
Taste the sauce and add extra salt and pepper if needed.
Slice the steaks against the grain into thin strips. Arrange them on serving plates and spoon the creamy sauce generously over the top.
Finish with freshly minced chives and serve immediately.

Variations
Swap strip steak for filet mignon if you prefer a more tender cut of beef.
Add sliced mushrooms to the skillet for extra flavor and texture.
Use shallots instead of red onion for a milder taste.
For a lighter version, substitute half-and-half for the heavy cream.
Fresh parsley can replace chives for a different herb flavor.
Serve the steak over mashed potatoes, rice, or buttered noodles for a heartier meal.
Storage/Reheating
Store leftover Steak Diane in an airtight container in the refrigerator for up to 3 days.
Reheat gently in a skillet over low heat until warmed through. Add a splash of cream or broth if the sauce thickens too much.
Microwave reheating also works in short intervals, stirring between each interval to keep the sauce smooth.
Freezing is not recommended because cream-based sauces can separate after thawing.
FAQs
What is Steak Diane?
