  • Serves 2
  • Active time: 20 minutes
  • Total time: 1 hour


  • 2 Tbsp. butter
  • 2 Tbsp. olive oil, divided

  • 2 MOINK tenderloin filets
  • ¼ cup grated Gruyère cheese

Cooking instructions

  1. Heat the butter and 1 tablespoon oil in a large skillet over medium heat. Add the onion, and sprinkle with salt and pepper. Cook, stirring occasionally, 30 minutes or until the onions begin to brown and caramelize. Add the thyme and sherry and cook 15 minutes longer, until the onions are browned.
  2. While the onions cook, sprinkle the filets with salt and pepper. Heat the remaining 1 tablespoon oil in a cast-iron skillet over medium-high heat. Brown the filets 2 minutes on each side.
  3. Preheat the broiler to high. Top each filet with the onions and cheese. Broil 1 minute or until the cheese is browned and melty.
