4 beef tenderloin steaks (6 ounces each)
1 teaspoon steak seasoning
2 tablespoons butter
1 cup sliced fresh mushrooms
1/2 cup reduced-sodium beef broth
1/4 cup heavy whipping cream
1 tablespoon steak sauce
1 teaspoon garlic salt with parsley
1 teaspoon minced chives

Directions

Season both sides of the beef tenderloin steaks with steak seasoning.
In a large skillet, melt butter over medium-high heat. Add steaks and cook 3–4 minutes per side for medium-rare, or until desired doneness. Remove steaks and set aside to rest.
In the same skillet, add mushrooms and sauté for 3–4 minutes until tender.
Stir in beef broth, heavy cream, steak sauce, and garlic salt with parsley. Bring to a simmer and cook 2–3 minutes until slightly thickened.
Return steaks to the skillet, spooning sauce over the top to coat. Cook 1–2 more minutes to heat through.
Garnish with minced chives before serving.

Steak Diane is best served immediately. Leftovers can be stored in an airtight container in the refrigerator for up to 1 day. Reheat gently in a skillet over low heat to preserve tenderness.

FAQs

Can I cook the steaks ahead of time?

You can sear the steaks ahead, but the sauce is best prepared fresh to maintain flavor.

How do I get the sauce thick without flour?

Simmering the sauce allows it to reduce naturally. For a thicker consistency, add a small slurry of cornstarch and water.

Can I make this gluten-free?

Yes, just ensure your steak sauce is gluten-free.

What side dishes pair well?

Mashed potatoes, roasted vegetables, or a simple green salad complement the rich sauce beautifully.

Can I use frozen mushrooms?

Yes, but fresh mushrooms give the best texture and flavor.
