Grilled Steak & Blue Cheese Crostini

Ingredients

  • 1 lb flank steak or sirloin
  • 1 baguette, sliced into 1/2-inch rounds
  • 4 oz crumbled blue cheese
  • 2 tbsp olive oil, plus more for brushing
  • 1 tbsp fresh rosemary, minced
  • 2 cloves garlic, minced
  • 1 tsp coarse black pepper
  • 1/2 tsp sea salt
  • 1/4 cup balsamic glaze
  • Fresh parsley, chopped, for garnish

Instructions

  1. 1

    Pat steak dry and season generously with salt, pepper, minced rosemary, and minced garlic. Let it rest at room temperature for at least 15 minutes.

  2. 2

    Preheat your grill to medium-high heat (400-450°F). Lightly brush the baguette slices with olive oil on both sides.

  3. 3

    Place the seasoned steak on the hot grates and grill for 4-6 minutes per side for medium-rare, or until your desired doneness is reached. Remove steak and let rest for 5-10 minutes.

  4. 4

    While the steak rests, grill the baguette slices for 1-2 minutes per side, until golden brown and crisp. Watch closely to prevent burning.

  5. 5

    Thinly slice the rested steak against the grain into bite-sized pieces. Aim for uniform slices for easy assembly.

  6. 6

    To assemble, place a few slices of grilled steak onto each crostini. Top with a generous sprinkle of crumbled blue cheese.

  7. 7

    Drizzle each crostini with balsamic glaze and garnish with fresh chopped parsley before serving immediately.

Why this recipe works best on a clean grill

A clean grill makes this recipe easier because the grates release food evenly, the heat moves predictably, and old grease does not smoke over the fresh ingredients. When carbon buildup sits on the grate, it can leave bitter flavors, create flare-ups, and make delicate foods stick right when they should sear.

Before cooking, preheat the grill fully, scrape the grate with a bristle-free tool, and lightly oil the surface. If your grill has yellow flames, heavy smoke, stubborn hot spots, or a greasy smell before the food goes on, it may need a deeper cleaning before your next cookout.
