Ingredients
Equipment
Method
- Pat the steak dry with paper towels. Slice the steak against the grain into thin strips, about 1/4-inch thick. In a medium bowl, toss the steak strips with 1 tbsp olive oil, garlic powder, onion powder, 1/2 tsp salt, and black pepper. Let marinate at room temperature for at least 15 minutes, or up to 30 minutes for more flavor.
- Preheat your air fryer to 375°F (190°C). If using an oven, preheat to 400°F (200°C).
- Brush both sides of the baguette slices with 2 tbsp olive oil and sprinkle lightly with 1/4 tsp garlic powder and a pinch of salt. Arrange in a single layer in the air fryer basket (working in batches if necessary) or on a baking sheet.
- Air fry for 5-7 minutes, flipping halfway, until golden brown and crisp. For the oven, bake for 7-10 minutes, flipping halfway. Set aside.
- While the crostini are toasting, pour the balsamic vinegar into a small saucepan. Bring to a simmer over medium heat. Reduce heat to low and continue to simmer, stirring occasionally, for 5-7 minutes, or until the vinegar has thickened to a syrupy consistency and coats the back of a spoon. Be careful not to over-reduce; it will thicken further as it cools. Remove from heat and set aside.
- Heat a cast iron skillet over medium-high heat until very hot. Add the marinated steak strips in a single layer (cook in batches if needed to avoid overcrowding). Sear for 1-2 minutes per side for medium-rare, or longer for desired doneness. Remove steak from skillet and let rest on a cutting board for 2-3 minutes before slicing into bite-sized pieces if they are too large.
- To assemble, place a few pieces of seared steak onto each toasted crostini. Top with a piece of torn burrata cheese. Drizzle generously with the balsamic glaze.
- Garnish with fresh chopped chives and optional parsley. Serve immediately.
Notes
Pro Tips for Making This Burrata Steak Crostini Appetizers
When I’m making these delicious bites, I always have a few tricks up my sleeve to ensure they turn out absolutely perfect. Cooking is all about those little details that make a big difference, and I want to share my favorite insights to help your Burrata Steak Crostini Appetizers shine.
My Secret Trick: I always make sure to let the cooked steak rest for at least 5-10 minutes before slicing it. This allows the juices to redistribute, resulting in incredibly tender and flavorful steak for your crostini. Trust me, patience here pays off!
For the perfect crostini, I recommend brushing your baguette slices generously with olive oil and a touch of garlic powder before toasting. This creates a wonderfully crisp base that stands up beautifully to the steak and burrata, preventing any sogginess.
When reducing your balsamic glaze, keep a close eye on it! You want it to thicken to a syrupy consistency, but not burn. A low, gentle simmer is best, and I always stir occasionally to ensure even reduction. This rich glaze is truly the crown jewel of these appetizers.
Lastly, assemble these delightful bites right before serving for the freshest texture. While you can prep the steak, glaze, and crostini ahead, combining them at the last minute ensures the baguette stays perfectly crisp and the burrata remains wonderfully creamy.
Fun Variations for Burrata Steak Crostini Appetizers
One of the greatest joys of cooking is getting creative and making a recipe truly your own! While I adore the classic Burrata Steak Crostini Appetizers, there are so many delightful ways to add your personal touch or cater to different tastes. My sister loves when I introduce a little heat, and a friend often asks for a touch of sweetness beyond the glaze!
Herbaceous Twists
Instead of just chives and parsley, try experimenting with other fresh herbs. A sprinkle of fresh basil or a few small sprigs of thyme can add a wonderfully aromatic dimension. Sometimes, I even infuse the olive oil for the crostini with a rosemary sprig for an extra layer of flavor!
Sweet & Savory Swaps
For a touch of extra sweetness, especially if your balsamic isn’t super sweet, consider adding a thin slice of fig or a dollop of fig jam under the burrata. Or, if you’re feeling a bit adventurous, a tiny sprinkle of crumbled blue cheese alongside the burrata could offer a sharp, tangy contrast that works beautifully with the steak.
Vegetable Boost
While the focus is on steak, a thin slice of roasted red bell pepper or a small dollop of caramelized onions placed beneath the burrata can add another layer of flavor and texture. It’s a fantastic way to introduce a hint of smoky sweetness that complements the savory steak.
What to Serve With Burrata Steak Crostini Appetizers
These savory bites are so satisfying on their own, but sometimes a little something extra just completes the experience. When I’m serving these Burrata Steak Crostini Appetizers, I love thinking about what complements their rich flavors without overpowering them. My mom always says a good appetizer sets the tone for the whole meal!
I often pair these crostini with a light, crisp green salad tossed with a simple vinaigrette. The freshness and acidity cut through the richness of the steak and burrata beautifully, providing a lovely contrast.
Another wonderful accompaniment is a small bowl of marinated olives. Their briny, tangy flavor offers a delightful palate cleanser between bites of the crostini, and they’re so easy to prepare.
For a comforting beverage pairing, a dry red wine, like a Cabernet Sauvignon, complements the robust flavor of the steak perfectly. Or, if you prefer non-alcoholic options, a sparkling cider or even a chilled sparkling water with a lemon twist would be lovely.
How to Store Burrata Steak Crostini Appetizers
I know how tempting it is to want to make a big batch, and while these Burrata Steak Crostini Appetizers are best enjoyed fresh, I do have some tips for handling any delicious leftovers, or for prepping components ahead of time. Preserving flavors and textures is key to enjoying them again!
Storing Components Separately
The best way to store these appetizers is to keep the components separate. Store any leftover cooked steak in an airtight container in the refrigerator for up to 3-4 days. The balsamic glaze can be kept in a sealed jar in the fridge for up to 2 weeks. The crostini bread, if not yet assembled, can be stored in an airtight container at room temperature for a couple of days to maintain its crispness.
Reheating and Enjoying Leftovers
When you’re ready to enjoy leftover steak, gently warm it in a skillet or microwave until just heated through. Reheat crostini in a toaster oven for a few minutes to crisp them up again. My personal tip for revitalizing leftovers is to always assemble them fresh! This ensures your crostini retains its crunch and the burrata remains creamy and cool, tasting as delightful as the first time.
Nutritional Benefits
While we often focus on the joy and flavor of homemade treats, these Burrata Steak Crostini Appetizers also offer some noteworthy benefits. The sirloin or flank steak provides a fantastic source of lean protein and essential iron, contributing to energy and muscle health. Paired with fresh herbs, it’s a treat that combines satisfying indulgence with simple, wholesome ingredients, showing that gourmet can be nourishing too.
FAQs

Absolutely! The balsamic glaze can be made up to a week ahead of time. Store it in an airtight container in the refrigerator. Gently warm it before serving to achieve the perfect drizzling consistency for your crostini.

Yes! You can easily make these gluten-free by using your favorite gluten-free baguette or other sturdy gluten-free bread slices. Simply follow the same toasting instructions to create the perfect base for your Burrata Steak Crostini Appetizers.
