How to Make Steak Crostini
-
Prepare Chimichurri: In a blender, combine roasted red peppers, parsley, red wine vinegar, smoked paprika, garlic cloves, lemon juice, pepper, salt, and Korean chili flakes. Blend until smooth, then slowly add olive oil to achieve a vibrant consistency. Set aside to let flavors meld.
-
Caramelize Onions: Heat unsalted butter in a skillet over medium heat. Add sliced onions and cook, stirring occasionally, until they turn golden brown and sweetly fragrant (about 20 minutes). Stir in balsamic vinegar and brown sugar, cooking for an additional 2 minutes. Set aside to cool.
-
Mix Garlic Butter: In a bowl, soften unsalted butter and mix it with minced garlic and fresh parsley. This will add a delightful garlic richness to your crostini. Set aside.
-
Grill Steaks: Preheat your grill to 500°F. Season the filet mignon steaks with salt and pepper. Grill them for 4-5 minutes on each side for medium-rare. Once cooked, let the steaks rest for about 10 minutes before slicing.
-
Prepare the Crostini: Preheat your oven to 400°F. Slice the baguette into ½-inch pieces and lightly brush with olive oil. Bake for 1-2 minutes per side until golden and crispy.
-
Assemble Crostini: Thinly slice the grilled steaks. Layer the sliced steak onto the toasted baguette pieces, followed by caramelized onions and a generous dollop of garlic butter. Top with chimichurri and serve immediately to enjoy the burst of flavors!

Expert Tips for Steak Crostini
- Quality Matters: Choose the best filet mignon you can find; quality meat will elevate the steak crostini significantly and enhance the overall flavor.
- Let It Rest: After grilling, rest the steaks for at least 10 minutes before slicing; this allows juices to redistribute, ensuring tender bites.
- Don’t Overcook: Aim for medium-rare for the filet mignon; overcooking can lead to a dry texture, which detracts from your steak crostini.
- Perfect Toasting: Keep an eye on your baguette slices while toasting; they can burn quickly. You want them golden and crisp for the best crunchy texture.
- Well-Balanced Chimichurri: Taste and adjust your chimichurri seasoning before serving; it’s crucial for ensuring your steak crostini has that perfect flavor combination.
How to Store and Freeze Steak Crostini
Fridge: Store leftover steak crostini in an airtight container for up to 3 days, ideally without the chimichurri to maintain crispiness.
Freezer: For longer storage, wrap individual toasted baguette pieces in plastic wrap and freeze for up to 2 months. Steaks should be sliced before freezing, and chimichurri can be frozen in ice cube trays.
Reheating: To reheat, bake the frozen baguette slices at 350°F for about 5-7 minutes, and warm the steak in a skillet over low heat before assembling the crostini again.
Make-Ahead Tips: Prepare the chimichurri and caramelized onions a day in advance to save time before serving your indulgent steak crostini.
