How to Make Baked Brie with Caramelized Onions

  1. Preheat the Oven: Begin by setting your oven to 350°F (175°C) to ensure the Brie bakes perfectly. This temperature allows for a warm and gooey center without overcooking.

  2. Caramelize the Onions: In a skillet, sauté sliced onions in olive oil or butter over medium heat. Cook for about 20 minutes, stirring occasionally, until the onions are golden brown and wonderfully soft.

  3. Prepare the Brie: While the onions are caramelizing, place the Brie in a suitable baking dish. For extra flavor, feel free to drizzle balsamic vinegar over the top.

  4. Bake the Brie: Transfer the baking dish to the oven and let it bake for approximately 15 minutes, or until the cheese is gooey and soft to the touch. Keep an eye on it to achieve the ideal melt!

  5. Serve: Once baked, top the warm Brie with your luscious caramelized onions, sprinkle with fresh herbs, and serve immediately with crusty bread or crackers for the perfect bite.

Baked Brie with Caramelized Onions Recipe FAQs

What kind of Brie cheese should I use for this recipe?
Absolutely! The best choice for this recipe is a soft, creamy Brie cheese, which can be easily found at most grocery stores. If you can’t find Brie, feel free to substitute it with Camembert, another delightful soft cheese that has a similar texture and flavor profile. Just make sure it’s at room temperature before baking for the best melt!

How should I store leftover Baked Brie with Caramelized Onions?
After enjoying your delicious Baked Brie, store any leftovers in an airtight container in the refrigerator. It will stay fresh for up to 2 days. Be sure to let the Brie cool completely before sealing the container to prevent moisture build-up, which can affect its texture.

Can I freeze Baked Brie with Caramelized Onions?
Yes! You can freeze Baked Brie without toppings for up to 2 months. Wrap it tightly in plastic wrap, followed by aluminum foil to avoid freezer burn. When you’re ready to enjoy it again, simply thaw it in the fridge overnight. To reheat, place it back in a preheated oven at 350°F (175°C) for about 10-15 minutes until it’s warmed through and gooey again.

What if my caramelized onions turn out too dark or burnt?
If your onions are turning too dark while caramelizing, it’s likely the heat is too high. Reduce the heat to medium-low and stir them more frequently. For the best results, take your time—ideal caramelization can take about 20 minutes. If they do get a little burnt, just scrape off the burnt bits and mix the remaining caramelized onions with some fresh ones to balance the flavor!

Are there any dietary considerations for Baked Brie with Caramelized Onions?
Yes, if you’re serving it to guests with dietary restrictions, make sure to check if they have any allergies, especially to cheese or gluten from the crusty bread. You can serve it with gluten-free crackers or fresh vegetable sticks as an alternative. Additionally, for a vegetarian-friendly option, simply ensure that you use vegetarian-friendly cheese and no animal rennet in your Brie.

Can I prepare the caramelized onions in advance?
Very much so! I recommend making your caramelized onions ahead of time. You can prepare them in advance and store them in the fridge for up to 3 days. Just gently reheat them on the stove before topping your baked Brie, so they’re warm and ready to enhance that gooey goodness!
