Do I have to remove the rind on the brie cheese?

NO! It is perfectly safe to eat the rind. We found, in this recipe, the brie melts a little easier if the rind on the brie is thinned a little. This is done by gently running a sharp knife over the rind and takes just a few seconds.

What is the key to caramelizing onions?

Time! This process can't be rushed if you want that amazing caramelized finish to the onions. It takes about an hour. We keep caramelized onions in our freezer to use as needed in recipes. See How To Caramelize Onions for more notes and detailed instructions.

Can I serve this on plain sliced baguettes instead of crostini?

The crunch of the crostini is a big element in this appetizer, but it can be served on a plain slice of baguette. For more notes and make ahead tips see Homemade Crostini .

Instructions

Make Caramelized Onions

Peel and thinly slice the onions.
Add onions and butter to a cast iron skillet over medium heat. Cook, stirring frequently until onions are caramelized. Caramelizing onions takes about an hour - make these in advance and keep on hand for using in recipes.

Make Crostini

Spread the baguette slices in a single layer on a lined baking sheet pan. Drizzle, spray, or brush with olive oil. Bake at 375°F for 5-10 minutes or until lightly browned.
Remove once done and set aside until ready to assemble.

Prepare Brie

Using a sharp knife scrape over the rind on the top and bottom of the brie. This will remove some of the rind making the brie melt a little easier on the crostini. It is absolutely fine to eat the rind on the brie, but for this recipe we find it melts a little easier if it is thinned out.
Slice the brie into slices about 1/4 inch thick.

Assemble Crostini

Place crostini on a baking sheet pan.
Top each crostini with 1-2 teaspoons caramelized onions.
Place a slice of brie on top of the onions.
Broil for 2-3 minutes until the cheese is melted.
Remove from oven. Garnish with chopped parsley (OPTIONAL). Serve warm.

Notes

Make Ahead of Time. These crostini take just minutes to assemble if the caramelized onions and crostini are already done making this a great recipe for unexpected guests. Ready in just minutes, easy to assemble, and delicious!

Cheese. If you aren't a fan of brie substitute swiss or gruyere cheese. Leave the rind on the brie or thin it out by gently running a sharp knife over it before slicing.

Caramelized Onions. Make these in large batches and keep in the refrigerator or freezer to use in dishes. See How to Caramelize Onions for more notes and detailed instructions.

Crostini. Make the crostini up to a day ahead of time and store in an airtight container on the counter. See Homemade Crostini for more notes and detailed instructions.
