Ingredients

Scale
  • 1 lb beef sirloin or tenderloin, thinly sliced
  • 8 oz fresh button mushrooms, sliced
  • 1 medium yellow onion, sliced
  • 2 garlic cloves, minced
  • Fresh parsley, chopped (optional, for garnish)
  • 2 cups beef broth
  • 1 tablespoon Dijon mustard
  • 1 cup sour cream
  • 2 tablespoons all-purpose flour (use gluten-free flour for gluten-free option)
  • 2 tablespoons butter (use olive oil for dairy-free option)
  • 1 tablespoon olive oil
  • Salt and freshly ground black pepper, to taste

Instructions

1. Cut the beef into thin strips against the grain for tenderness. Season with salt and pepper, then lightly dredge with flour.

2. In a large skillet, heat butter and olive oil over medium heat. Add sliced mushrooms and onions, cooking until soft and golden brown.

3. Push mushrooms and onions to the sides of the pan, add beef strips in the center, and sear quickly until browned.

4. Stir in minced garlic until fragrant, then add beef broth and Dijon mustard. Let the sauce simmer gently.

5. Remove from heat and stir in sour cream until creamy and smooth, avoiding boiling.

6. Season with salt and pepper to taste. Serve immediately over buttered egg noodles, mashed potatoes, or steamed rice.

Notes

Slice the beef thinly against the grain for extra tenderness.

Don’t skip the flour dredging—it helps thicken the sauce.

Avoid boiling the sauce after adding sour cream to prevent curdling.
