How to Make Irresistibly Delicious Steak Crostini
Step 1: Prepare the Chimichurri Sauce
Start by blending all chimichurri ingredients together except for olive oil at high speed. Pour this mixture into a bowl and slowly incorporate olive oil. Set aside at room temperature or refrigerate until needed.
Step 2: Make Caramelized Onions
In a skillet over medium heat, melt 2 tablespoons of unsalted butter. Add sliced onions with a pinch of salt. Cook for about 20 minutes while stirring occasionally. Once caramelized, add brown sugar and balsamic vinegar; season with salt and pepper. Stir for another 2 minutes before setting aside.
Step 3: Create Garlic Butter
Mix softened butter with finely minced garlic and chopped parsley in a bowl. Set aside at room temperature to meld flavors.
Step 4: Grill the Steak
Preheat your grill to about 500°F. Generously season filet mignon steaks with salt and pepper on all sides. Grill each side for 4 to 5 minutes for medium-rare doneness or adjust according to preference.
Step 5: Toast the Baguette Slices
Let steaks rest for about 10 minutes while you slice baguettes into half-inch pieces if not done already. Brush each side with olive oil and bake at 400°F on a baking sheet for 1-2 minutes per side until golden brown.
Step 6: Slice the Steaks
Once rested, slice steaks into thin strips approximately ÂĽ inch thick.
Step 7: Assemble Your Crostini
Lay out crostini on a clean surface or tray. Start building by spreading caramelized onions on each slice followed by garlic butter, then place a piece of steak on top. Finish with a drizzle of chimichurri sauce for extra flavor. Adjust as per your liking!

Common Mistakes to Avoid
Cooking the Irresistibly Delicious Steak Crostini can be fun, but there are a few common pitfalls you should steer clear of.
- Skipping the Seasoning: Failing to properly season your steak can lead to bland flavors. Make sure to generously coat your filet mignon with salt and pepper before grilling.
- Overcooking the Steak: Cooking the steak for too long will make it tough. Use a meat thermometer to ensure it’s cooked to your desired doneness, especially if you prefer medium-rare.
- Using Stale Bread: Old baguette slices won’t provide the desired crunch. Always use fresh bread and toast it until golden and crispy for that perfect texture.
- Ignoring Ingredient Quality: Low-quality ingredients can ruin the dish. Use fresh herbs, quality olive oil, and ripe roasted red peppers for the best flavor.
- Rushing Assembly: Putting together your crostini too quickly can result in messy layers. Take your time to layer each ingredient thoughtfully for a beautiful presentation.
