How to Make Beef Fillets With Cognac Onion Sauce

1. Preheat oven to 400°F (200°C).
2. Season beef fillets generously with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
3. Heat 2 tablespoons olive oil in an ovenproof cast-iron skillet over medium-high heat. Sear beef fillets for 3 minutes per side, until nicely browned.
4. Remove fillets from skillet and set aside, reserving the pan drippings.
5. Add 1 tablespoon butter to the skillet. Melt over medium-high heat.
6. Add 1 medium yellow onion (sliced into rings), 1 medium red onion (sliced into rings), and sauté for 5 minutes.
7. Add 4 green onions (sliced), 2 shallots (minced), and 2 cloves garlic (minced). Sauté for 10-15 minutes, or until onions are softened and lightly caramelized, stirring occasionally.
8. Pour in 1/4 cup cognac and 1/2 cup beef broth. Scrape up any browned bits from the bottom of the pan.
9. Cook over medium-high heat, stirring constantly, until the liquid reduces and slightly thickens (about 5-7 minutes).
10. Return the beef fillets to the skillet, placing them on top of the onion mixture.
11. Cover the skillet with aluminum foil.
12. Bake for 15-20 minutes, or until a meat thermometer inserted into the thickest part of the fillet registers 140°F (60°C) for medium-rare.
13. Remove the skillet from the oven. Remove fillets from the skillet and let them rest, loosely covered, for 10 minutes before serving.
14. While fillets rest, continue to cook the onion mixture over medium heat, stirring frequently, until the sauce thickens further (about 5 minutes).
15. Season the sauce with salt and pepper to taste.
16. Slice the beef fillets and serve them over the luxurious cognac onion sauce.
