Vegan Pear and Brie Quesadilla Recipe with Caramelized Onions

These Vegan Pear Brie & Caramelised Onions Quesadillas are drizzled with a balsamic glaze that make it the ultimate fall quick meal!

Quesadillas are one of those endlessly versatile dishes: crisp tortillas hugging a warm, flavorful filling that works with virtually any cuisine. These vegan pear and Brie quesadillas are a simple, elegant twist ideal for autumn. They combine thinly sliced pear, creamy vegan Brie, sweet caramelised onions and fresh thyme, then finish with a sticky, tangy balsamic glaze that lifts every flavor. If you enjoy quick, satisfying meals that taste like more effort went into them than you actually made, this is one to keep in your weeknight repertoire.

I love meals that come together fast, and these quesadillas are ready with only about 9 minutes of active prep. The caramelised onions do take a bit of time to soften and sweeten, but the process is simple and mostly hands-off. The balsamic glaze is the small step that makes a big difference: reduced low and slow until slightly thickened, it adds concentrated sweet-tart intensity that pairs beautifully with pear and Brie. Don’t skip it — it’s what turns good into memorable.

A quick note about who inspired this pairing: in our kitchen, the person who often takes the lead on sauces devised the balsamic glaze for this recipe, and it was immediately clear it was the perfect match. The thyme adds an herbal lift that complements both the fruit and the cheese, while the caramelised onions bring mellow sweetness and depth. Together, these elements create a balanced savory-sweet profile that feels seasonal and comforting.

These quesadillas are crisp outside and tender inside. The pears keep their shape and add a juicy texture, the vegan Brie melts into a creamy layer, and the caramelised onions bring a luscious softness. The balsamic glaze provides the final contrast: a glossy, syrupy finish that enhances and binds the flavors. A little glaze goes a long way, and any extra can be stored and used on salads, roasted vegetables, or sandwiches.

These Vegan Pear Brie & Caramelised Onions Quesadillas are drizzled with a balsamic glaze that make it the ultimate fall quick meal!

Ingredients

Balsamic Glaze / Reduction

• 1/2 cup balsamic vinegar
• 1–2 tablespoons coconut sugar, cane sugar or sucanat
• 1/2 teaspoon fine sea salt
• 1/2 teaspoon ground black pepper

Quesadillas

• 1/2 medium onion, peeled and thinly sliced
• 1 pear, cored and thinly sliced
• 2 ounces vegan Brie cheese, sliced or torn
• 3–4 sprigs thyme, leaves removed
• 6–8 tortillas
• 1 tablespoon vegan butter or coconut oil

Instructions

Balsamic Glaze

1. In a small pot over medium-high heat, combine the balsamic vinegar, sugar, salt and pepper. Stir to dissolve the sugar and bring to a gentle simmer.
2. Reduce heat slightly and simmer, stirring occasionally, until the glaze thickens enough to coat the back of a spoon — about 5–10 minutes. Watch carefully, as it can thicken quickly. Remove from heat once it reaches a syrupy consistency.

Quesadillas

1. Heat the vegan butter or coconut oil in a skillet over medium-high heat.
2. Add the sliced onions; they should sizzle when they hit the pan. Reduce heat to medium and allow the onions to caramelise for about 15 minutes, stirring every 5 minutes. If the pan dries out, add 1–2 tablespoons of water at a time to keep the onions from burning and help them finish caramelising.
3. Assemble the quesadillas: on one tortilla, layer pear slices, thyme leaves, vegan Brie and a generous portion of the caramelised onions. Top with a second tortilla.
4. Place the assembled quesadilla in a dry pan over medium-high heat or on a mini grill. Heat one side for about 3 minutes, then flip and heat the other side for another 3 minutes, until both sides are crisp and the cheese is melted. Alternatively, divide the filling between two tortillas and fold each over for easier flipping.
5. When crisp and heated through, slice with a pizza cutter or sharp knife. Drizzle with the balsamic glaze and serve immediately.

Notes

• This recipe is vegan.
• To make gluten-free, use gluten-free tortillas.
• Caramelising onions can be done more slowly for deeper flavor, but this quicker method produces similar results in about 30 minutes total.
• Extra balsamic glaze stores in the refrigerator and is excellent on salads, roasted vegetables, or sandwiches.
