This sounds delicious! Here's a recipe for Beef Tenderloin Tips in a Creamy Sour Cream Sauce, along with tips for variations and serving ideas:

Ingredients:

* 1 pound beef tenderloin, cut into 1-inch pieces

* 1 tablespoon olive oil

* 1/2 teaspoon salt

* 1/4 teaspoon black pepper

* 1/2 cup chopped onion

* 1/2 cup sliced mushrooms

* 1/4 cup all-purpose flour

* 1 cup sour cream

* 1/4 cup beef broth

* 1 tablespoon Dijon mustard

* 1 teaspoon dried thyme

* 1/4 cup chopped fresh parsley (for garnish)

Instructions:

1. Sear the Beef: Heat olive oil in a large skillet over medium-high heat. Season beef tenderloin tips with salt and pepper. Sear the beef on all sides until nicely browned, about 3-4 minutes per side. Remove beef from skillet and set aside.

2. Sauté the Vegetables: Add onion and mushrooms to the skillet and cook until softened, about 5 minutes.

3. Make the Sauce: Stir in flour and cook for 1 minute, stirring constantly. Gradually whisk in sour cream, beef broth, Dijon mustard, and thyme. Bring the sauce to a simmer, stirring constantly until thickened.

4. Combine and Finish: Return beef to the skillet, coating well in the sauce. Reduce heat to low and simmer for 5 minutes, or until the beef is cooked through.

5. Serve: Garnish with chopped parsley and serve immediately over mashed potatoes, rice, or your favorite pasta.

Tips and Variations:

* Add Flavor: Feel free to experiment with additional flavors! You can add a teaspoon of garlic powder or a pinch of cayenne pepper for a kick.

* Mushrooms: Use your favorite mushrooms (cremini, shiitake, portobello) or even a mix.

* Wine: For extra richness, deglaze the pan after searing the beef with a splash of red wine.

* Creamy Additions: Add a touch of cream cheese or Gruyere cheese to the sauce for extra richness.

* Sides: Serve with roasted vegetables, green beans, or a simple salad.

Enjoy!
