These crostini hit that sweet spot between fancy and fast. Crisp toasts, melty Brie, and a glossy bacon jam come together in 15 minutes and feel like something you’d order at a wine bar. You don’t need special equipment, and the ingredients are easy to find.
Jump to RecipeServe them for last-minute guests, date night, or when you want a small bite that tastes like you put in way more effort than you did.
What Makes This Special
This appetizer balances savory, sweet, salty, and creamy in one bite. The bacon jam gets a quick, deep flavor from a fast reduction with brown sugar, vinegar, and onions—no hour-long simmer needed. Brie melts into the toast without turning greasy.
Best of all, everything comes together quickly on the stovetop and under the broiler, so you can go from zero to elegant in minutes. It’s versatile, too: top with herbs, fruit, or a drizzle of hot honey to match the mood.
Shopping List
- Baguette (1 medium), sliced into 1/2-inch rounds
- Thick-cut bacon (8 ounces), chopped
- Yellow onion or shallots (1 cup finely diced)
- Brown sugar (2 tablespoons)
- Apple cider vinegar (2 tablespoons)
- Maple syrup (1 tablespoon), or honey
- Dijon mustard (1 teaspoon)
- Smoked paprika (1/2 teaspoon), optional but great
- Freshly cracked black pepper (to taste)
- Brie cheese (8 ounces), chilled for easier slicing
- Olive oil (2 tablespoons), for brushing the bread
- Fresh thyme (optional), for garnish
- Sea salt (a pinch), if needed
Instructions
- Preheat and prep. Set your oven to broil. Line a sheet pan with foil for easy cleanup.Slice the baguette and brush lightly with olive oil on one side.
- Toast the crostini. Broil the bread on the top rack for 1–2 minutes per side until golden and crisp. Watch closely—broilers go from perfect to burnt fast.
- Cook the bacon. In a skillet over medium heat, cook the chopped bacon until crisp, about 5–7 minutes. Spoon off all but 1 tablespoon of fat.
- Soften the onions. Add diced onion (or shallots) to the skillet.Cook 2–3 minutes, stirring, until softened and lightly golden.
- Build the jam. Stir in brown sugar, cider vinegar, maple syrup, Dijon, smoked paprika, and a few grinds of black pepper. Simmer, stirring, until syrupy and jammy, 2–3 minutes. The mixture should coat a spoon and look glossy.
- Taste and adjust. Add a pinch of salt if needed, more vinegar for tang, or more maple for sweetness.You want a bold sweet-sour balance to cut through the Brie.
- Slice the Brie. Cut Brie into small wedges or rectangles that fit your toasts. Leaving the rind on is fine—it adds flavor and helps the cheese hold shape.
- Assemble. Top each crostini with a slice of Brie. Spoon 1–2 teaspoons of warm bacon jam on top.
- Optional melt. For extra ooze, return crostini to the oven for 30–45 seconds to soften the Brie.Don’t overdo it—Brie melts quickly.
- Finish and serve. Garnish with fresh thyme. Serve warm or at room temperature. These are best within 20 minutes for peak texture.

Tips for the Best Results
- Keep the jam balanced with vinegar so it does not taste flat or too sweet.
- Toast the bread well so it stays crisp under the topping.
- Assemble right before serving for the best texture.
- Use chilled Brie for cleaner slicing and neater crostini.
- Do not over-broil the bread or it will burn fast.
- A small spoonful of jam is enough to avoid soggy toasts.
- The bacon jam can be made ahead and reheated gently.
- Fresh herbs or a drizzle of hot honey make a nice finishing touch.
How to Store
Keep leftover bacon jam in an airtight container in the fridge for up to 1 week.
It will thicken as it chills; rewarm gently in a skillet or microwave to loosen. Brie is best sliced fresh, but you can pre-slice and refrigerate it for 1 day, covered. Toasts are best made the day of; if you must prep ahead, toast them and store uncovered at room temperature for up to 6 hours to maintain crispness.
Assemble just before serving.
Benefits of This Recipe
- Speedy but special: You get big, complex flavor in 15 minutes without long simmering or specialty ingredients.
- Make-ahead friendly: The bacon jam can be cooked days ahead, making party assembly effortless.
- Flexible: Works with different breads, cheeses, and toppings to fit what you have.
- Texture contrast: Crunchy toast, silky Brie, sticky jam—every bite is balanced and satisfying.
- Scalable: Double or triple easily for a crowd without extra stress.
What Not to Do
- Don’t skip the acidity. The vinegar is crucial. Without it, the jam tastes flat and overly sweet.
- Don’t over-broil. Crostini burn quickly. Keep the oven door slightly ajar and your eyes on them.
- Don’t overcook the Brie. If it gets too hot, it can leak oil and lose its creamy texture.
- Don’t drown the toast. Too much jam will slide off and make the bread soggy.A teaspoon or two is perfect.
- Don’t forget seasoning. A pinch of salt and fresh pepper at the end sharpens the flavors.
Alternatives
- Bread swaps: Use ciabatta slices, mini toasts, or sturdy crackers. Gluten-free baguette works well—toast it thoroughly for crunch.
- Cheese swaps: Camembert, triple-cream brie, or even goat cheese for a tangier bite. For a firmer option, try Fontina or Taleggio.
- Sweeteners: Replace maple syrup with honey or a touch of pomegranate molasses for a deeper note.
- Vinegar choices: Balsamic or red wine vinegar can sub for cider vinegar.Start with less and adjust to taste.
- Herbs and finishes: Fresh rosemary, chives, or parsley. Add a drizzle of hot honey or a few drops of balsamic glaze for flair.
- Fruit accents: Thin apple or pear slices under the Brie add brightness. Fig slices or pomegranate seeds are great for holidays.
- No pork option: Use turkey bacon and a splash of liquid smoke, or make a quick onion “jam” by doubling onions and skipping bacon entirely.
FAQ
Can I make the bacon jam ahead?
Yes.
Make it up to 1 week in advance and refrigerate. Rewarm gently and stir in a splash of water if it’s too thick. Taste and rebalance with a little vinegar if needed.
Do I need to remove the Brie rind?
No.
The rind is edible and helps the cheese hold its shape when warmed. If you prefer a fully creamy bite, you can trim the rind, but you’ll lose some structure and flavor.
What if I don’t have a broiler?
Toast the bread in a 425°F (220°C) oven for 5–7 minutes, flipping once. A stovetop grill pan works too; just brush the slices with olive oil first.
How do I keep the crostini crisp?
Toast the bread well and assemble right before serving.
If you need to hold them, layer cheese first and add the jam at the last moment. Avoid covering tightly while warm to prevent steam from softening the toasts.
Can I use pre-cooked bacon?
You can, but flavor will be lighter. If using, warm it with a teaspoon of oil, then proceed with the onions and the rest of the ingredients to build a jammy sauce.
What wine pairs well with this?
Try a dry sparkling wine (like Brut) or a Pinot Noir.
For white, a crisp Sauvignon Blanc or lightly oaked Chardonnay balances the richness.
How many crostini does this make?
About 20–24 pieces, depending on baguette size and how generously you top each one. For larger gatherings, double the jam and have extra Brie on hand.
