🛒 Ingredients
For the Grilled Tenderloin:
- 1.5 lbs beef tenderloin, trimmed
- 1 tablespoon olive oil
- 1 clove garlic, minced
- 1 lemon, juiced
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the Creamy Dill Sauce:
- ½ cup mayonnaise
- ¼ cup sour cream
- 2 tablespoons fresh dill, chopped
- 1 teaspoon lemon juice
- 1 clove garlic, finely minced
- Salt and pepper to taste
🔥 Instructions
1. Prep the Tenderloin
Brush the beef tenderloin with olive oil, then season generously with salt, pepper, minced garlic, and fresh lemon juice. Let it rest while you preheat the grill.
2. Heat Up the Grill
Preheat your grill (or grill pan) to medium-high heat. You want it hot enough to get a flavorful sear.
3. Grill the Tenderloin
Place the tenderloin on the grill. Cook each side for 4–6 minutes, turning occasionally, until a nice crust forms and the internal temperature reaches 145°F (63°C) for medium-rare. Adjust cook time for your desired doneness.
4. Make the Dill Sauce
In a small bowl, combine the mayonnaise, sour cream, dill, lemon juice, garlic, salt, and pepper. Mix until smooth and creamy. Keep chilled until ready to serve.
5. Rest and Slice
Once cooked, let the tenderloin rest for 5 minutes to keep the juices locked in. Slice into medallions and serve with a generous spoonful of the creamy dill sauce.
Serving Suggestions
- Pair with roasted baby potatoes, grilled asparagus, or a fresh garden salad.
- For a low-carb option, serve with grilled zucchini or cauliflower mash.
- A glass of chilled white wine or light red (like Pinot Noir) complements beautifully!
