Method
Prepare the Beef Tenderloin
- 1
Trim and Season the Beef
Trim any excess fat from the beef tenderloin. Season generously with salt and black pepper on all sides.

Sear the Beef
In a skillet, heat olive oil over medium-high heat. Once hot, add the beef tenderloin and sear for about 3-4 minutes on each side until a nice crust forms. Reduce heat to medium and continue cooking until the internal temperature reaches 130°F for medium-rare, about 10-12 minutes. Remove from heat and let rest for 5 minutes before slicing.

Cook the Onions and Mushrooms
In the same skillet used for the beef, melt the butter over medium heat. Add the sliced onions and cook until they are softened and golden brown, about 5-7 minutes. Add the mushrooms, garlic, and thyme, and cook for an additional 5 minutes, stirring occasionally until the mushrooms are tender. Season with salt and pepper to taste.
Make the Creamy Horseradish Sauce

Mix the Sauce
In a bowl, combine sour cream, prepared horseradish, Dijon mustard, lemon juice, salt, and black pepper. Stir well until smooth and creamy. Adjust seasoning to taste.
