Preparing the Steak
The star of this beef appetizer is most definitely the steak! Each steak bite is topped with a juicy slice of steak and garnished with crème fraiche and steak sauce. For this recipe, I recommend using only ribeye steak or filet mignon steak; the more tender the meat, the better! I like to use my ‘Ribeye Steak Recipe’, preparing the steak with balsamic vinegar, herbs and garlic. This recipe makes for the most delicious steak! Once you have the steak prepared, allow it to rest for about 5 minutes. Next, trim off the fatty parts and slice the steak into thin slices that would fit easily on top of each crostini slice. Don’t make the cuts too big! These crostini need to be two-biters!
Preparing the Bread
While you’re preparing the steak, you can also prepare the bread or base for these steak crostini. You can use a variety of breads such as French baguette, classic white bread, or even brioche bread! Mini burger buns or slider buns will also work! I typically make these with thinly sliced and toasted rustic baguette. The thin and crispy bread goes so well with the toppings. Just slice the baguette into 1/3-inch slices and place onto a baking pan. Brush the top of each slice lightly with olive oil and then broiler for a few minutes. It’s the fastest way to toast a large amount of bread! If you want to use slider buns, use just one-half for each appetizer.
Guacamole & Toppings
My steak crostini are so delicious when enjoyed with guacamole! Once I have the steak done and the bread toasted, I spread a generous amount of homemade guacamole onto each slice. You can also use store bought, premade guacamole. And if you want even more flavor, try using my ‘Chimichurri Sauce’ in place of the guacamole for a flavor explosion! Add the sliced steak on top of the guacamole and, if desired, add a tiny dollop of crème fraiche on top. You’ll love the creamy flavor. And for the finishing touch, I like to drizzle my favorite steak sauce over each steak crostini. Garnish the top with micro greens for a pop of color!
Homemade Guacamole Recipe
My favorite guacamole recipe that I use for everything! Simply combine these ingredients in a large bowl and then use a potato masher or two large forks and press the avocado into a puree. You can also use a molcajete and pestle. Here’s the easy recipe I use:
- 2 to 3 large, ripe avocados
- 1 medium shallot, diced
- 1/4 cup chopped cilantro
- 1 small tomato, seeded and diced
- 2 to 3 tbsp freshly squeezed lime juice
- salt and pepper, to taste
- 2 garlic cloves, pressed
- 1 tbsp mayonnaise or sour cream; optional

Guacamole & Steak Crostini Recipe
- 1/2 large, thin baguette
- 1 ribeye steak, prepared as desired
- 1/2 cup guacamole
- 2 tbsp steak sauce
- 2 tbsp crème fraiche, optional
- microgreens, for garnish
- Prepare the steak first. I recommend using prime steak cuts such as ribeye or filet mignon; if the steak isn't soft enough, it will be harder to enjoy. Once the steak is done, allow it to rest for 5 minutes. Using a sharp knife, cut away any fatty pieces and cut the steak into small, thin pieces that fit easily on top of the bread.
- Prepare the baguette. While the steak is resting, it's the perfect time to prepare the crostini. Brush the sliced bread lightly with olive oil and toast until golden brown. Add the guacamole. You can make a batch of homemade guacamole using my recipe in the post above or use store-bought. Both are great options!
- Top each crostini with the sliced steak. Add the garnishes! I like to drizzle my favorite steak sauce over the top of each steak crostini and add a tiny dollop of crème fraiche. You can also add micro greens. Enjoy it warm! This appetizer is best served warm. If needed, keep it warm in the oven until you're ready to enjoy!
