Ingredients
- 4 cloves garlic minced
- 1 tablespoon chopped fresh rosemary
- 1 tablespoon chopped fresh thyme leaves

- 1 tablespoon olive oil
For the horseradish cream sauce
- ½ cup sour cream

Instructions
- To make the horseradish cream sauce, combine sour cream, mayonnaise, prepared horseradish and chives; season with salt and pepper, to taste. Set aside in the refrigerator until ready to serve.
- Preheat oven to 275 degrees F. Line a baking sheet with foil and coat with nonstick spray.

- Using paper towels, pat tenderloin dry. Drizzle with olive oil; season with garlic mixture, gently pressing to adhere.
