Caramelized Onion Baked Brie in Crescent Roll Crust (Brie en Croûte)

A reliable signature appetizer is worth keeping on hand for impromptu gatherings. When a last-minute girls’ night pops up, you want something quick to serve. One favorite is Baked Kahlua Pecan Brie, which I enjoy with apple slices and alongside coffee-flavored cocktails or a glass of wine. For a gluten-friendly alternative I skip the classic brie en croute, but when I do wrap brie in dough I make this caramelized onion brie en croute. This caramelized onion baked brie crescent round is always a crowd pleaser.

The caramelized onion baked brie crescent round is a straightforward mix of butter and thinly sliced onions cooked until deeply browned, then heaped onto a round of brie and wrapped in crescent dough.

Baked Brie with Caramelized Onions Ingredients

The beauty of this caramelized onion brie en croute is its simplicity: just four basic ingredients.

To make the caramelized onions and assemble the baked brie you’ll need:

• 1 large onion (Vidalia or sweet onion works well)
• 4 tablespoons butter
• One 5-inch brie round
• One can of crescent rolls or a crescent sheet (crescent rounds can also be used)

How to Make Caramelized Onion Baked Brie Crescent

Begin by thinly slicing the onion. Melt the butter in a sauté pan, add the sliced onion, and stir to coat. Cook over medium-low heat for about 20 minutes, stirring occasionally so the onions brown evenly. Toward the end of cooking, add a splash of water to the pan to loosen and absorb the fond—the flavorful browned bits on the bottom.

When the onions are a rich brown and soft, remove from heat. Unroll the crescent dough onto a baking sheet without separating the triangular pieces—this creates one continuous sheet that’s easier to wrap. If using a crescent sheet, lay it flat. Trim the top rind off the brie, place the cheese rind-side down in the center of the dough, and spoon the caramelized onions over the exposed cheese, leaving the pan butter behind.

Gather the edges of the dough up and around the brie, sealing all sides so the cheese and onions are enclosed. Spoon any remaining butter from the pan over the top of the dough for extra flavor and browning.

Bake at 325°F (160°C) for 12–15 minutes, or until the dough turns golden brown. Let the baked brie rest for about 15 minutes before slicing so the cheese firms slightly and doesn’t run out.

What to serve with baked brie?

This baked brie pairs beautifully with pretzel crackers, regular crackers, or fresh apple slices. It’s also fine to serve with sliced baguette, crostini, or sturdy crackers—after a couple of glasses of wine, some guests might happily dig in with a fork and knife.

Different Kinds of Baked Brie Toppings?

If you prefer something sweeter than caramelized onions or want an alternative topping, here are a few tasty options:

• Jam-topped baked brie – try apricot jam, peach jam, blackberry preserves, or apple butter.
• Candied nuts and Kahlua brie – toss pecans or walnuts with brown sugar, spread over the cut brie, and wrap in dough.
• Fresh fruit and bourbon bacon – crumble cooked bacon and top with diced peaches, plums, or apricots; whisk bourbon with honey and drizzle over the fruit and bacon before wrapping.
