Ingredients for Montasio Sweet Onion Tart

Here’s what you’ll need to make this savory tart recipe:

• 1 sheet of puff pastry (store-bought or homemade)
• 2 large sweet onions, thinly sliced

• 1 teaspoon balsamic vinegar
• 1 cup Montasio cheese, grated (or Gruyère as a substitute)
• 1 egg (for egg wash)
• Salt and pepper, to taste

How to Make Montasio Sweet Onion Tart

Step 1: Prepare the Onions

Start by heating olive oil in a large skillet over medium heat. Add the sliced onions and cook, stirring frequently, until they begin to soften and caramelize, about 20-25 minutes. Stir in the balsamic vinegar and season with salt and pepper to taste. Continue to cook until the onions are deep golden brown and caramelized. Set aside to cool.

Step 2: Prepare the Puff Pastry

Preheat your oven to 375°F (190°C). Roll out the puff pastry sheet on a floured surface to fit your tart pan (around 9 inches in diameter). Press the pastry into the pan, trimming any excess pastry from the edges.

Step 3: Assemble the Tart

Spread the caramelized onions evenly over the puff pastry. Sprinkle the grated Montasio cheese over the top, ensuring an even coverage. If you prefer a slightly more intense flavor, you can add some freshly cracked black pepper on top.

Step 4: Bake the Tart

Brush the edges of the puff pastry with a beaten egg to give it a golden finish when baked. Place the tart in the preheated oven and bake for 25-30 minutes, or until the pastry is golden and crispy and the cheese has melted.

Step 5: Garnish and Serve

Once the tart is done baking, remove it from the oven and let it cool for a few minutes. Garnish with fresh thyme for an added touch of color and flavor. Slice and serve warm as a main or side dish.

Tips for the Perfect Montasio Sweet Onion Tart

• Use high-quality cheese: Montasio is ideal for this recipe, providing a smooth, creamy texture that pairs wonderfully with the caramelized onions. If you can’t find Montasio, Gruyère or Emmental are great substitutes.
• Caramelize the onions slowly: Caramelizing the onions over low heat allows them to develop their full sweetness and depth of flavor. Be patient—it’s worth it!
• Experiment with flavors: Try adding a handful of spinach or arugula to the tart before baking for a bit of freshness, or use rosemary instead of thyme for a different flavor profile.

This tart is also a great addition to your side dishes to impress collection. Pair it with a Roasted Butternut Squash Salad for a hearty vegetarian meal.

Why Montasio Cheese is the Perfect Choice for This Tart

Montasio cheese is an Italian cow’s milk cheese known for its smooth texture and slightly nutty, creamy flavor. It melts beautifully, making it a great choice for tarts, gratins, and other baked dishes. In this tart, the Montasio cheese blends perfectly with the caramelized onions, adding richness without overpowering the other ingredients. It’s a great alternative to more common cheeses like cheddar or mozzarella.
