How to Make Beef Fillets With Cognac Onion Sauce
- Preheat oven to 400°F (200°C).
- Season beef fillets generously with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
- 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.
- Remove fillets from skillet and set aside, reserving the pan drippings.
- Add 1 tablespoon butter to the skillet. Melt over medium-high heat.
- Add 1 medium yellow onion (sliced into rings), 1 medium red onion (sliced into rings), and sauté for 5 minutes.
- 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.
- Pour in 1/4 cup cognac and 1/2 cup beef broth. Scrape up any browned bits from the bottom of the pan.
- Cook over medium-high heat, stirring constantly, until the liquid reduces and slightly thickens (about 5-7 minutes).
- Return the beef fillets to the skillet, placing them on top of the onion mixture.
- Cover the skillet with aluminum foil.
- 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.
- Remove the skillet from the oven. Remove fillets from the skillet and let them rest, loosely covered, for 10 minutes before serving.
- While fillets rest, continue to cook the onion mixture over medium heat, stirring frequently, until the sauce thickens further (about 5 minutes).
- Season the sauce with salt and pepper to taste.
- Slice the beef fillets and serve them over the luxurious cognac onion sauce.
