Ingredients

Scale
  • 1 large T-bone steak (about 16 oz / 450 g), preferably USDA Choice or higher for marbling
  • 2 tablespoons olive oil (for brushing)
  • Salt and freshly ground black pepper, to taste
  • 4 tablespoons unsalted butter, softened
  • 1 tablespoon fresh parsley, finely chopped
  • 1 teaspoon fresh thyme leaves
  • 1 small garlic clove, minced
  • 1 teaspoon lemon juice
  • Pinch of salt and pepper
  • 2 large sweet onions (Vidalia or Maui), sliced into ¼-inch rings
  • 1 cup all-purpose flour
  • 1 teaspoon smoked paprika
  • 1 teaspoon salt
  • 1 teaspoon baking powder
  • 1 cup cold sparkling water
  • Vegetable oil (canola or peanut oil recommended) for frying

Instructions

  1. Slice onions into ¼ inch rings and separate gently. In a bowl, whisk together flour, smoked paprika, salt, and baking powder. Slowly add cold sparkling water, whisking until smooth. Chill batter in fridge.
  2. Combine softened butter with parsley, thyme, garlic, lemon juice, salt, and pepper. Mix well, shape into a log with plastic wrap, and chill until ready to use.
  3. Take steak out of fridge 30 minutes before cooking to reach room temperature. Pat dry, brush with olive oil, and season with salt and pepper.
  4. Preheat grill or grill pan to high heat (around 450°F).
  5. Grill steak about 5-6 minutes per side for medium-rare (130°F internal temperature). Use tongs to flip. Rest steak tented with foil for 5-7 minutes.
  6. Heat vegetable oil to 375°F in a deep pan. Dip onion rings in batter, let excess drip off, and fry in batches for 2-3 minutes until golden and crisp. Drain on paper towels and season with salt.
  7. Slice herb butter into rounds and place on hot steak while it rests to melt and infuse flavor.
  8. Serve steak with crispy onion rings, optionally garnished with fresh thyme or parsley.

Notes

Let steak come to room temperature before grilling for even cooking. Use an instant-read thermometer to check doneness. Keep batter cold and oil at 375°F for crispy onion rings. Rest steak after grilling to redistribute juices. For dairy-free, use vegan butter and gluten-free flour for batter. Double-dip onion rings for extra crunch but avoid too thick batter.
