A single wheel of brie wrapped in flaky galette pastry and crowned with jammy balsamic red onions — the low-drama, high-drama appetizer you’ll actually love serving.

Baked Brie with Jammy Balsamic Red Onions — A Warm, Runny Center That Steals Winter Parties

Despite my deep affection for cheese, to the point that one of my favorite things to do on a New York City weekend is to dip into Murray’s and treat us to something crumbly or aged or rich and runny, I don’t love cheese plates. It feels really good to get this off my chest. At first, it was just a budget issue; I still feel the sticker shock from the first time I tried to put together one of those cute boards with five or six different wedges on them, plus the crackers, breads, pickles, dried fruit, toasted almonds, olives, cured meats, and all of the other minimum requirements of our latter-day horns of plenty. But I was also put off by the waste. Even though so much went unfinished, the leftovers were unsalvageable, as fingers, forks, knives, and crumbs got into everything (a particularly shuddering thought in the age of Covid). Instead, when people come over, or what I remember of it, I prefer to focus on one or two decadent, attention-grabbing things and nothing grabs attention on a cold winter day like warm, runny cheese.

Baked brie was all the entertaining rage in the 1970s and 80s. Nothing was more glamorous but accessible, an imported cheese that everyone knew and could pronounce. But as Americans got more sophisticated about imported cheese — manchego! Humboldt Fog! — in a crushing fall from grace, brie became the opposite of chic. And this is where my interest piqued — dated and unhip, you say? Where can I sign up?

Thus, this is baked brie, my way. First, I use my easy galette dough for a flaky pastry that tastes a million times better than most frozen puffed pastry and requires no extra grocery store trip. I’ve never been a fan of the sweet compotes and fruity jams usually paired with brie, but I love a thin layer sweet-sour jammy red onions under and over the cheese — here, softened in butter, then wilted down further with salt, pepper, balsamic vinegar, and brown sugar. A paper-thin slick of smooth Dijon mustard offsets the sweetness, a sprinkling of thyme gives it an herbal element, a scattering of sesame seeds on top adds a little extra crackle, or you can skip all three and it’s still delicious. Brie — and yes, even commercial, grocery store brie works well here — is attainably-priced and even the basic stuff warms up beautifully, so no need to splurge here. Plus, it often comes in 8-ounce rounds, absolutely perfect for our tiny, at-home New Years celebrations this week to send 2020 packing.

Practical Tips

Tip

Use an easy galette dough instead of frozen puff pastry for a flakier, tastier crust.

“I use my easy galette dough… tastes a million times better than most frozen puffed pastry.”

Make a thin layer of jammy balsamic red onions: soften in butter, then wilt with salt, pepper, balsamic and brown sugar.

“softened in butter, then wilted down further with salt, pepper, balsamic vinegar, and brown sugar.”

A thin smear of Dijon offsets sweetness — use sparingly for balance.

“A paper-thin slick of smooth Dijon mustard offsets the sweetness.”

Grocery-store brie works — no need to splurge; 8-ounce rounds are perfectly sized.

“even commercial, grocery store brie works well here… it often comes in 8-ounce rounds, absolutely perfect.”

Optional toppings (thyme, sesame) add herb and textural contrast; omit them if you prefer simpler.
