Fontina Cheese and Caramelized Onion Tart
Make a savory tart using slightly expired Fontina cheese and caramelized onions. Ensure the cheese is still safe to consume by checking for any signs of spoilage such as mold or an off smell.
Ingredients
- 1 sheet of puff pastry
- 2 tablespoons olive oil
- 2 large onions, thinly sliced
- 1 teaspoon balsamic vinegar
- 1 cup grated Fontina cheese
- Salt and pepper to taste
Instructions
Preheat the oven to 400°F (200°C).
Heat the olive oil in a large skillet over medium heat.
Add the sliced onions to the skillet and cook until caramelized, about 20 minutes.
Stir in the balsamic vinegar and season with salt and pepper.
Roll out the puff pastry sheet and place it on a baking sheet.
Spread the caramelized onions evenly over the puff pastry, leaving a small border around the edges.
Sprinkle the grated Fontina cheese over the onions.
Bake in the preheated oven for 25-30 minutes, or until the pastry is golden brown and the cheese has melted.
Allow the tart to cool for a few minutes before serving.
Slice and serve warm.
