Need a fall-flavored appetizer for your next party? Treat your guests to a plate filled with these delicious Cheese Crostini with Caramelized Onions, Apples and Thyme.
These bite-sized toasted bread slices act like little plates for all of their tasty toppings. They can be sweet (think these Pomegranate Crostini with Ricotta and Mint) or savory (like these Crostini with Whipped Feta and Tomatoes).
But the fall-flavored ingredients that grace these Cheese Crostini with Caramelized Onions, Apples and Thyme are my current jam. Together they make a delicious way to kickstart any party.
With a minimal number of ingredients in this appetizer recipe, quality ingredients are key to making the most of every bite. That’s why I chose to use Kerrygold® Mild Cheddar Cheese Slices. A quick spin under the broiler effortlessly melts this creamy, mellow cheese made with grass-fed milk.
The remaining ingredients – toasted baguette slices, caramelized onions, green apple slices and a sprinkle of thyme – give you that irresistible sweet, savory and crunchy combination that just can’t be beat and will definitely have you reaching for more.
But before you dive head first into this Cheese Crostini with Caramelized Onions, Apples and Thyme recipe, we have a few points of clarification:
What is the difference between Bruschetta and Crostini?
It’s easy to be confused by the two terms as they both refer to toasted bread.
Crostini actually means “little toasts” in Italian. Think small slices of bread that have been toasted. (This Crostini with Savory Tomato, Bacon and Apple Jam recipe is another one of our favorites.)
Bruschetta, on the other hand, is usually made by toasting larger pieces of bread. Think slices from a loaf of sourdough. Bruschetta is typically served warm after being rubbed with a garlic clove and drizzled with olive oil.
We most often see bruschetta with a variety of tomato-based toppings like our Balsamic Bruschetta or Fresh Tomato Arugula Bruschetta, but the flavor combinations for topping bruschetta are truly endless.
A crostini is supposed to be a bite-sized snack, so a baguette is the only bread I use for crostini recipes. It’s small, round size is perfect for appetizers. It takes only a few minutes under a warm broiler to toast to perfection.
Can crostini be made ahead of time?
I will often toast the bread slices earlier in the day and loosely cover them until assembly time. If I know I’m going to be re-toasting the crostini like in this recipe, I often under-toast them the first time around so they become perfectly toasted and warmed through the second time under the broiler.
Doesn’t it take a long time to caramelize onions?
It does take time to achieve caramelization in your onions (rather than simply sautéing them), but the extra effort is soooooooo worth it. Plus you can freeze them to use later! Check out all of our tips for caramelizing onions HERE.
