Ingredients

  • 4 beef tenderloin steaks
  • 2 Tbsp lard
  • 1 tsp salt
  • 1/2 tsp white pepper
  • 4 white onions, sliced into rings
  • 2 cups beef stock
  • Vinegar (wine)

Instructions

  1. Slash fat edges of steaks to prevent curling.
  2. Melt lard in a skillet over medium heat.
  3. Add steaks and sear 2 to 3 minutes on each side until browned on the outside but still slightly red inside.
  4. Season steaks with salt and white pepper.
  5. Remove steaks from skillet and set aside to keep warm.
  6. In the same skillet, add white onion rings and cook until golden and caramelized.
  7. Deglaze the pan with beef stock and a splash of vinegar to make a sauce.
  8. Serve steaks topped with the caramelized onions and sauce.

Tips & Substitutions

For enhanced flavor, consider marinating the steaks in a mixture of vinegar and spices for a couple of hours before cooking. If you don't have lard, butter or olive oil can be used as substitutes. To achieve perfect caramelization, cook the onions slowly over medium-low heat, stirring occasionally. For more variations, explore other beef recipes that feature rich sauces.

Serving Suggestions

Serve the steak with caramelized onions over a bed of creamy mashed potatoes or alongside roasted vegetables for a complete meal. A fresh green salad with a tangy vinaigrette pairs well to balance the richness of the dish. For a heartier option, consider serving with crusty bread or browse more beef recipes for additional side ideas.

Storage & Reheating

Leftover steak and onions can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a skillet over low heat, adding a splash of beef stock or water to prevent drying out. Cover the skillet to retain moisture while warming through.

Frequently Asked Questions

Can I use a different cut of beef for this recipe?

Yes, while beef tenderloin is ideal for its tenderness, you can use ribeye or sirloin steaks. Just be sure to adjust the cooking time as these cuts may take longer to reach the desired doneness.

How can I make the sauce thicker?

To thicken the sauce, you can whisk in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons of cold water) during the deglazing step. Let it simmer for a few minutes until it reaches your desired consistency.

What kind of vinegar should I use?

Wine vinegar is recommended for its mild flavor, but you can also use balsamic or apple cider vinegar for a different taste. Each type will add a unique twist to the sauce, enhancing the overall dish.
