Gluten-free Caramelized Onion Crostinis

If I have learned anything since I started cooking, it is to have a good appetizer recipe (or a few) on hand for when you get invited to a party or are hosting. I might consider appetizers to be one of my favorite meals, however, for some reason I tend to have a tough time coming up for ideas in a pinch when I need to bring one to a party. I don't want you to be in the same predicament, so I created these Gluten-free Caramelized Onion Crostinis!

These bite-sized snacks are always a hit and are so easy to make! All you need are 5 ingredients and you can make them gluten-free or just with regular bread, whichever you choose. While these might not be "paleo friendly" or Whole30, they are a great option for so many people because they are fairly allergen friendly. I try to bring mostly allergen friendly food to a party so that almost anyone can enjoy some!

For the bread, if I am making these gluten, free, I like to use Udis baguettes. Otherwise a baguette from the bakery at the store does just fine! I make these with goat cheese, however if you don't like goat cheese you can also use Kite Hill cream cheese or any other spreadable cheese you prefer.

Tips for Gluten-free Caramelized Onion Crostinis:

  1. Use any bread that you like best, whether it is gluten-free or not. You can even use crackers if you are trying to make them even more bite-sized.
  2. I like goat cheese best, but you can also use any of your favorite spreadable cheese, like Kite Hill cream cheese.
  3. These are great to make ahead of time (but not the night before).

Instructions
 

  • Heat a pan to low heat and add 1 tablespoon olive oil. Thinly slice the onion and add to the pan. Cover and stir every couple minutes. Let them caramelize for about 30-35 minutes.
  • Turn the oven on broil and let it pre-heat. In the meantime slice the baguette into about 1 ½ inch slices. Place the slices on a sheet pan and lightly drizzle with olive oil.
  • Broil for about 3 minutes. Every oven is a bit different so it might take a little longer. Be sure to keep an eye on the bread, though, because it can burn quickly with the broiler. You want it to be just slightly toasted.
  • When the bread is toasted and the onions are caramelized, it is time to start building the crostini. Spread the goat cheese on the bread first, then the fig spread, then a small piece of prosciutto, and finally top with some onions.
  • Serve right away, or cover with foil and set out later for your guests! Enjoy!

Notes

  1. Use any bread that you like best, whether it is gluten-free or not. You can even use crackers if you are trying to make them even more bite-sized.
  2. I like goat cheese best, but you can also use any of your favorite spreadable cheese, like Kite Hill cream cheese.
  3. These are great to make ahead of time (but not the night before).
