Step‑by‑Step Instructions for Grilled Steak and Tomato Crostini
Step 1: Prepare Ingredients
In a mixing bowl, combine quartered cherry tomatoes with chiffonade-cut basil, ½ tablespoon of olive oil, dried oregano, and mozzarella pearls. Gently toss to ensure even coating. Set this vibrant tomato mixture aside to allow the flavors to meld while you focus on grilling the steak and bread for your Grilled Steak and Tomato Crostini.
Step 2: Preheat Grill
Prepare the grill by heating it to medium-high, aiming for around 375°F. This high temperature will create a beautiful sear on the steak. Ensure the grates are clean and oiled to prevent sticking. As the grill heats up, you’ll get ready to infuse the steak with that smoky, irresistible flavor.
Step 3: Grill Steak
Once the grill is hot, place your seasoned steak on the grates. Cook the steak for about 4–6 minutes per side, depending on your preferred doneness. For medium-rare, look for a nice char and an internal temperature of 130°F. After grilling, let the steak rest for 5 minutes; this ensures juicy, tender bites when cubed for your crostini.
Step 4: Prepare Bread
While the steak rests, slice rustic bread into ¾”-1” thick pieces. Brush one side of each slice with olive oil, then place them oil-side down on the grill. Grill each slice for about 1–2 minutes until golden brown with delightful grill marks. This will create the perfect crisp base for your toppings.
Step 5: Assemble Crostini
To assemble your Grilled Steak and Tomato Crostini, top each grilled bread slice with a generous amount of the prepared tomato mixture, followed by cubes of the grilled steak. Season with kosher salt and black pepper to taste, allowing the flavors to enhance this scrumptious appetizer.
Step 6: Garnish (optional)
For a finishing touch, sprinkle chopped Italian parsley over each crostini before serving. This adds a pop of color and an extra layer of flavor that complements the rich ingredients. Serve your vibrant Grilled Steak and Tomato Crostini warm to enjoy the full spectrum of flavors and textures, perfect for any gathering.
