Need a cool party appetizer idea with only a few ingredients? Rock this recipe for caramelized onion and brie crostini and see how easy it is to serve up fancy food.
Grab 2 large onions and slice into semicircles giving you long medium-thick strips. Toss them into a hot pan (medium-high heat) with 1 tablespoon of canola (or vegetable) oil. Let them sizzle and brown a bit, stirring every minute to make sure they don’t burn for about 5 minutes and then turn the heat down to medium-low.
Bump Up The Flavor
Now, you can take the long road with caramelizing your onions low and slow or you can give them a little pop and with some booze to speed things up and bump up the flavor! Deglaze the pan by pouring in ½ cup of amaretto or even whiskey if you prefer it a little less sweet. I totally eyeball the measurement here – can’t really go wrong with a little extra.
Stir the caramelized onions around to scrape up all the “fond” which is the brown goodness that builds up on the bottom. It’s sweet and savory and what makes the caramelized onions SO GOOD. Cook for 15 more minutes low and slow, salt to taste, and set aside to cool.
Preheat your oven to 500 degrees, folks because it’s time to get your crostini on. Slice a fresh french baguette into ⅓ – ½ inch slices. If it’s pre sliced, score! Lay the pieces out on a rimmed baking pan and brush lightly with olive oil. Bake for 3-5 minutes or just until golden, then set aside.
Assemble the Goods
Brie is a mild and buttery-smooth cheese. Ideal for melting! Slice off squares that fit perfectly on top of the crostini (with the crostini still on the rimmed baking pan). Once every little toast has a slice of brie, spoon a bit of the caramelized onion on top.
Pop the whole pan back into the oven and broil on high just enough to see the brie begin to melt; probably 1-3 minutes. Keep your eye on them!
Remove your caramelized onion and brie crostini from the oven and immediately transfer to a platter to serve. Afterall, who will be able to resist – the smell is amazing.
