I'm all for an easy to whip out and make appetizer, and baked brie with caramelized onions does the trick. It's impressive, it's decadent, and it takes no time at all to make (as long as you have your caramelized onions made a head of time - and yes, I admit, this takes a while).

Baked brie with caramelized onions, balsamic vinegar, and rosemary. Is there any better flavor combination?

It's also a total crowd please, fits in well with your charcuterie plate, and sounds oh-so-bougee when you tell people about it. Baked brie has been a mainstay at all my entertaining get togethers - like we're talking my mom was making this at her parties 15 years ago. I love it because it's so versatile. While I love a baked brie in puff pastry, this time, we're forgoing it, and we're going to let the simple ingredients shine. The flavor combinations are literally endless, but this baked brie with caramelized onions just hits different.

What does Baked Brie Taste Like?

If you've never had brie cheese before, you're missing out. This creamy, rich and lush cheese has flavors reminiscent of butter, but with earthy notes baked in. Lots of people also report nutty flavors as well. Because the cheese texture itself is creamy and can be quite heavy, you'll often see it paired with sweeter options and variations (though definitely not exclusively). As you can probably guess, this particular flavor was inspired by the classic French onion soup (albeit without the gruyere).

Interesting to note though, there are tons of different varieties of brie cheese worldwide, and each creator and region will bring a different taste to the mix. So definitely experiment to see what works best for you and your palate.

Baked Brie Cheese Recipe Variations

The flavor of brie cheese makes it so easy to pair with other flavor combinations, so by no means is this an exhaustive list. I would totally encourage you to get creative and try whatever looks interesting to you.

How to Serve Baked Brie

I like to make the baked brie in a bowl that's just slightly larger than the round of cheese itself. Otherwise, it tends to melt and go everywhere (especially if you cut into it). If your wrap it in puff pastry, this definitely helps keep it contained. This one we're just going to be very careful we don't over bake it (and if we do, the bowl will be there to catch us if we fall.

Once the brie comes out of the oven, I serve it in the bowl it's baked in on a platter, surrounded with small spoons or knives, and crackers or crostini. After that, everyone can just dig in and help themselves!

Wine Pairings

You can't have cheese without wine, obviously. Because brie pairs so well with different flavors and ingredients, the same is true for wine. Overall, it goes super well with acidic whites, like Chardonnay, which cuts through the fat with the acidity. It's important to keep in mind though, more mature brie cheeses develop more complex flavors as they age, so they'll need a more complex wine to stand with it. For this recipe in particular, I would stick with the Chardonnay, but don't be afraid to branch out and try a Pinot Noir with an older style of cheese.

How to Make Caramelized Onions

This is the real astrix on this recipe, because if you don't have the caramelized onions made ahead of time, this is not a simple or quick appetizer.

Making Baked Brie with Caramelized Onions

Once you've got the caramelized onions down, this couldn't be easier. Throw your round of brie in to a small, glass or ceramic baking dish. Add your caramelized onions and rosemary to the top, along with a bit of olive oil. Bake for 15-20 minutes. Drizzle balsamic vinegar over the top, and you're good to go.

  • 1 round brie cheese rind on
  • 3/4 C caramelized onions
  • 1 tablespoon olive oil
  • 1 tablespoon fresh rosemary leaves chopped
  • 1 tablespoon balsamic vinegar

Preheat your oven to 375°F.
Place the brie cheese in a dish that's just slightly larger than the brie itself. If you don't have something like this, just make sure you leave the rind in tact, and watch the brie as it cooks so it doesn't start melting everywhere.
Add the onions, oil, and rosemary to the cheese. Bake for 15-20 minutes.
Remove from the oven and drizzle with the balsamic. The cheese should be gooey and melted when you break into it.
Serve with crackers and crostini.
  • You can totally make this with puff pastry if you want. Just place the round of brie in the middle of the pastry, add all the ingredients on top (including the balsamic), and wrap before you bake in the oven for 20-25 minutes, until the puff pastry is golden.
