The Two-Bite Appetizer That Disappears Fast
If you’ve ever set out a spread and watched one thing vanish before everything else, you already understand these mini brie grilled cheese. There’s something irresistible about a warm, golden, gooey grilled cheese shrunk down to a single rich bite—crisp baguette on the outside, molten brie in the middle, jammy caramelized onions, and a schmear of fig jam for that sweet-salty contrast.
They look impressive on a board but come together with just a handful of ingredients, and the bulk of the work can be done a full day ahead. 🙌🏻
Why Baguette Beats Sliced Bread Here
I love a classic grilled cheese on soft white bread as much as anyone, but for a party, sliced baguette is the move.
Cut into ½-inch pieces, it gives you sturdy, perfectly portioned little sandwiches that hold their shape, crisp up beautifully, and won’t go soggy under a warm filling.
How to Caramelize the Onions
Don’t rush this part—real caramelized onions take time, and it’s worth every minute. Cook thinly sliced sweet onions low and slow in butter until they collapse into something jammy, sweet, and deeply golden (here’s my full guide on how to caramelize onions if you’d like the step-by-step). Season them at the very end as adding salt too early draws out water and slows down the browning.
Assemble Now, Cook Later
Spread brie on the bottom slices, add a small mound of onions, smear fig jam on top slices, and stack them up. You can do this early in the day, leave everything out at room temp, then griddle when guests arrive. Easy!
Pro tip: Butter the outside of the sandwich, not the pan. Spread softened butter on the top slice while the first side cooks. It toasts more evenly and you’ll use far less of it.
Cook Low and Slow for the Meltiest Middle
Patience over heat! Set your griddle or skillet to medium (any hotter and the baguette browns before the brie melts). Cook each side 2-3 minutes, until eep golden.
When you want them extra melty… here’s a little trick: if you’re not totally sure the center is molten, add a splash of water to the pan, then cover with a lid. Within about 30 seconds all the cheese should be epically melted.
What To Serve With Mini Grilled Cheese
Grilled cheese and tomato soup is a classic for a reason. I love serving these alongside my thick, creamy roasted tomato soup—set out little cups for dipping and watch people lose their minds. And for something sweet to round out the meal, a try of soft, chewy peanut butter cookies never lasts long. Total nostalgia!
Swaps & Variations
The brie-onion-fig combo is my favorite, but these minis are endlessly adaptable:
- Cheese: any good melty cheese works. Gruyère, fontina, sharp white cheddar, or taleggio for something funkier.
- Jam: swap fig for blackberry, apricot, or a spicy pepper jelly if you want a little heat (this was my grad school late night snack of choice!!)
- Add-ins: crisp bacon, thin apple or pear slices, arugula, or even a bit of whole-grain mustard.
Whether you’re hosting a holiday party, putting together a game-day spread, or just want a fun appetizer, these mini grilled cheese deliver every time. If you make them, I’d love to hear how they go over!

Mini Grilled Cheese with Brie & Caramelized Onions
Equipment
Ingredients
- 1 French baguette, sliced ½-inch thick pieces
- 5 Tbsp unsalted butter, divided
- 2 medium sweet onions, thinly sliced
- Kosher salt
- Freshly ground black pepper
- 6 oz triple creme brie
- ⅓ cup fig jam, store-bought or homemade
Instructions
- Caramelize the onions. Melt 2 Tbsp butter in a medium skillet over medium heat. Add onions then cook slowly, stirring occasionally, until caramelized and browned, about 30-40 minutes. Adjust heat and lower as needed if onions begin to brown too quickly. At the end, season onions with ½ tsp Kosher salt, then stir and remove from the heat. Set aside.
- Assemble the sandwiches. Slice and spread a thin layer of brie on each bottom slice of baguette. Top with about 1 heaping teaspoon of caramelized onions. Next, add about 1 tsp fig jam to each top slice of baguette. Place on top of the caramelized onions.
- Meanwhile, heat a griddle, skillet, or stove top grill to medium heat. Melt 2 Tbsp butter, then add sandwiches and cook until golden brown on both sides and cheese has melted, about 3-4 minutes (depending on the thickness of the bread and cheese). Note: While the first side is cooking, spread the top piece of bread from each sandwich with a little softened butter.
- Slice, then serve! Serve immediately, either whole or sliced on a diagonal and served as half sandwiches.
Notes
- Freshly grated cheese tends to melt quicker, so keep an eye on this if you substitute with a different cheese.
- Make-ahead (onions): Caramelized onions can be made up to 5 days ahead and refrigerated, or frozen up to 3 months.
- Make-ahead (sandwiches): I like to assemble these earlier in the day, then griddle fresh when ready to serve. Enjoy hot!
