For the Love of Cheese!
This recipe was part of my ongoing work with Midwest Dairy. I was super excited to be partnering with them again for the second Cheeseboard Chat event in 2021! The year before, I shared an entire series on dairy sustainability that culminated with a recap of our dairy farmer panel, cheesemonger-led cheese tasting, and how to build the perfect cheese and charcuterie board. You can read all about it HERE.

It’s always a treat for me to be able to talk with farmers and ask them questions. I’ve been fortunate to visit multiple dairy farms to see operations of all sizes and if there’s one thing I’ve learned, it’s that dairy farmers are deeply passionate about producing the highest quality, safest milk they can.
You and I are the end consumers they’re always thinking of, and I think of them every time I reach into the dairy case at my local grocery store. It comes full circle with recipes like this, so let’s get into it!
But I know you came for the recipe, so let’s turn our attention to this showstopper of a baked brie appetizer!
Ingredients You’ll Need
Simplicity is the name of the game around the holiday season, so no hard-to-find ingredients here. Make this easy baked brie appetizer recipe even easier by scheduling a grocery delivery. We partner with Instacart to create ready-to-shop lists for all our recipes. Just click HERE to get what you need!
- Triple cream brie. Get a wheel of brie vs. a wedge of brie so you’ll be able to easily wrap it
- Sheet of puff pastry. I’m not much of a baker so I use store-bought puff pastry sheets, but if you’re feeling ambitious and want to use homemade, go for it!
- Two large sweet onions (Vidalia or similar)
- Salted butter
- Brown sugar
- Balsamic vinegar
- Fresh thyme or a sprig of fresh rosemary
I like to use a small cast-iron skillet for my baked brie appetizers. This 14-oz. size seems to be perfect for an 8-oz. wheel of brie, which is a pretty standard size.
Make sure you also have a cutting board and share knife, plus a big skillet for caramelizing the onions.
How To Make Baked Brie in Puff Pastry
- Before starting anything, make sure the puff pastry dough is fully thawed. It’s best to pull it out to room temperature in advance or move it from the freezer to the fridge a day or two before you plan to cook your baked brie.
- When you’re ready to start, thinly slice the onions. Heat your large skillet over medium heat and melt the butter. Add the onions and cook, stirring occasionally, for a minimum of 20-25 minutes or until they are browned with a sweetened fragrance.
- Add the balsamic vinegar, salt, and brown sugar and stir to combine. As the mixture thickens, cook for an additional 5-10 minutes to reach a jam-like consistency. At this time, you can also preheat your oven to 400 degrees F.
- Remove the caramelized onions from heat and allow to cool slightly. At this point, spread the puff pastry onto a clean work surface or drape it over the skillet. Remove the brie from its packaging and place it in the center of the puff pastry.
- Spoon the caramelized onions on top of the cheese and around the sides. Sprinkle in the thyme and rosemary at random, then fold the edges of the puff pastry over the top. Crimp some of the folded edges if needed to seal it closed (see below).
- Place the wrapped brie into the cast iron skillet if it’s not already in there and bake for 20 minutes or until the flaky puff pastry is golden brown. Pull it out of the oven and allow it to cool slightly before serving. Enjoy!
Tips for Caramelized Onions and Baked Brie
To caramelize the onions, use low heat and at least 20 to 25 minutes of cooking time. 30 minutes is even better! It helps if you slice all the onion in similar-size slices so they cook at the same rate. I used two good sized onions and ended up with about 1 cup of caramelized onions when it was all said and done. They’ll reduce in size quite a bit, especially after you add the balsamic vinegar and brown sugar.
Don’t be intimidated because baked brie is actually much easier than your eyes might be telling you. Here are three tips to help you get the best result when you try this recipe:
- Thaw your puff pastry so it doesn’t break when you fold the edges. I made the mistake of skipping this critical step the first time I tried to make baked brie. And I haven’t made that mistake since!
- Leave the white rind on your wheel of brie. If you take it off before baking, you’ll likely have a big mess to clean up, so if you prefer not to eat the rind, carve it off after it’s finished baking
- Embrace the “elegantly disheveled” look! This recipe is not about perfection – whoever you’re serving this to will be blown away by the delicious flavors no matter what it looks like
And finally, it’s totally optional to add an egg wash on the corners of the dough if you want a shiny, extra golden finish. It might help your baked brie appetizer look more impressive, but it’s an optional extra step.
This recipe will make about 4 to 6 servings. If you want some contrasting flavors and textures, or you’re serving a bigger crowd, add these options to your serving platter:
- Fresh fruit, such as grapes, berries, apple slices or sliced pears , pomegranate
- Dried fruit, like dried cherries, apricots, or sliced mango
- Crunchy veggies, especially baby carrots, broccoli or cauliflower, or sliced bell pepper
- Honeycomb or hot honey drizzle, or orange marmalade, apricot preserves, or fig jam
- Mixed nuts, like pistachios, almonds, walnuts, or pecans
- Pita chips, crackers, or baguette slices
- Your favorite charcuterie meats, pepperoni, or summer sausage
Just remember to give your melty brie a little time to cool before you dig in. It’s going to taste incredible, but it’s not worth burning all your taste buds off!

- Preheat your oven to 400 degrees F. Place the thawed puff pastry in the center of a prepared baking sheet or small cast-iron skillet. Place the wheel of brie in the center.
- Spoon the caramelized onions over and around the wheel of brie. Sprinkle in the fresh thyme and rosemary, if using. Then fold the edges of the puff pastry over the top, crimping the edges if needed to seal.
