Beef Tenderloin Asturias

Ingredients

  • /4 cup olive oil
  • (6 ounce) beef tenderloin steaks
  • salt and pepper to taste
  • small onion, minced
  • tablespoon paprika
  • /4 cup dry white wine
  • /2 cup beef broth
  • ounces Spanish blue cheese, such as Cabrales or Valdeon
  • tablespoons chopped parsley

Instructions

  1. Step 1

    To begin, heat olive oil in a large skillet over medium-high until it shimmers. Season the tenderloin steaks generously with salt and pepper. Once the oil is smoking, carefully place the steaks in the pan and sear them on both sides until beautifully browned. Then lower the heat to medium and let them cook to medium-rare, about 6 minutes total, depending on thickness. Remove the steaks and set them aside, tented with foil to keep warm. Now, in the same pan, add the minced onion and cook until soft and translucent, about 5 minutes. Stir in the paprika and let it bloom for a minute. Crank up the heat to medium-high, pour in the white wine, and scrape up any browned bits. Let the wine reduce by half, then add the beef broth and simmer for 2 minutes. Finally, whisk in the crumbled blue cheese until it melts into a velvety sauce. Spoon it over the steaks and finish with a sprinkle of fresh parsley.

Chef's Tip

My secret is to bring the steaks to room temperature before cooking – this ensures even doneness and a perfect sear. Also, don’t let the blue cheese boil or it can turn grainy; just stir it in gently off the heat.

Storage Tips

Store leftover steak and sauce separately in airtight containers in the fridge for up to 3 days. Gently reheat the sauce on low heat, adding a splash of broth if it thickens too much, and briefly warm the steak in a skillet to avoid overcooking.

Variation Tips

For a complete keto meal, serve with roasted asparagus or cauliflower mash. Swap the blue cheese for goat cheese if you prefer a milder tang, or use ribeye steaks instead of tenderloin for a richer flavor.
