How to Make Baked Brie with Caramelized Onions
Preheat the Oven: Begin by setting your oven to 350°F (175°C). This temperature will ensure that your brie melts beautifully and turns golden brown.
Caramelize the Onions: In a skillet, heat 2 tablespoons of olive oil or butter over medium heat. Add the thinly sliced large onion. Cook low and slow for about 20-25 minutes, stirring occasionally, until the onions are soft, sweet, and a rich golden brown.
Prepare the Brie: While the onions are caramelizing, take an 8 oz round of brie cheese and place it on a baking tray or in a cast-iron skillet. For added melty perfection, score the top of the brie lightly.
Top and Bake: Once the onions are ready, spoon them generously over the brie. Bake in the preheated oven for about 15 minutes, or until the cheese is gooey and bubbly.
Serve Delightfully: Remove from the oven and let it cool slightly. Garnish with fresh thyme or rosemary if desired. Serve warm with crusty bread or crackers for a delightful appetizer experience.
Optional: Sprinkle some chopped walnuts for an extra crunch.
