Pan-seared chateaubriand steak with red wine sauce

Pan-seared Chateaubriand steak with red wine sauce is a classic, luxurious dish that is perfect for special occasions or a delightful dinner. The combination of a perfectly cooked beef fillet and a rich red wine sauce creates a harmonious symphony of flavors that is sure to impress. Follow these steps to cook this exquisite recipe.

Instructions:

1. Prepare the Ingredients:
- Allow the beef fillet to come to room temperature about 30 minutes before cooking.
- Finely chop the onion.
2. Season the Beef:
- Pat the beef fillet dry with paper towels.
- Season both sides of the beef fillet generously with salt and a dash of black pepper.
3. Heat the Pan:
- Heat a large skillet over medium-high heat and add 2 tablespoons of olive oil. Allow the oil to become hot but not smoking.
4. Sear the Beef:
- Carefully place the seasoned beef fillet into the hot skillet.
- Sear the beef for about 3-4 minutes on each side for a medium-rare finish. Adjust the cooking time as needed depending on the desired level of doneness.
- Once seared, remove the beef from the skillet and cover it loosely with aluminum foil. Let it rest while preparing the sauce.
5. Prepare the Red Wine Sauce:
- In the same skillet, reduce the heat to medium.
- Add 2 tablespoons of butter and let it melt.
- Add the finely chopped onions and sauté until they become translucent, about 2-3 minutes.
- Pour in the red wine, scraping the bottom of the skillet to release any browned bits. Let the wine reduce by half, simmering for about 4-5 minutes.
6. Finish the Sauce:
- Once the sauce has reduced, return any juices that may have collected from the resting beef back into the skillet.
- Stir well to combine and let the sauce simmer for an additional 1-2 minutes until it thickens slightly.
7. Serve:
- Slice the rested beef fillet into medallions.
- Spoon the red wine sauce generously over the steak slices.

8. Optional Garnish:
- Garnish with finely chopped fresh herbs, if desired.
9. Enjoy:
- Serve immediately with your favorite side dishes.

Pan-seared chateaubriand steak with red wine sauce FAQ:

What is the best cooking time for a medium-rare chateaubriand steak?

For a medium-rare finish, sear the beef fillet for about 3-4 minutes on each side. Adjust the time slightly longer or shorter based on your preference for doneness.

How should I store leftover chateaubriand steak?

Store leftover chateaubriand steak in an airtight container in the refrigerator for up to 3 days. To reheat, consider using low heat in a skillet to maintain tenderness.

Can I substitute red wine with another ingredient in the sauce?

You can use beef broth or balsamic vinegar as a substitute for red wine, but the flavor profile will change. Beef broth will provide a savory depth, while balsamic vinegar adds sweetness and acidity.

What pan size is best for pan-searing a chateaubriand steak?

A large skillet, preferably around 10-12 inches in diameter, is ideal for evenly searing the chateaubriand steak allowing sufficient space for proper browning.

How do I know when the steak is done cooking?

Use a meat thermometer to check doneness: for medium-rare, aim for an internal temperature of 130-135°F (54-57°C). If you don't have a thermometer, pressing the steak gently can also give an idea of doneness; it should feel firm but springy.

Tips:

- Ensure the beef fillet is at room temperature before cooking for even cooking.

- Use a meat thermometer to check the internal temperature of the steak; aim for 125°F (51°C) for rare, 135°F (57°C) for medium-rare, and 145°F (63°C) for medium.

- Let the steak rest for a few minutes after searing, to allow the juices to redistribute.

- Choose a good quality red wine for the sauce, as its flavor will greatly influence the final taste.

- Deglaze the pan with the red wine to capture all the flavorful bits left from searing the steak.
