Ingredients
- Dough: 1 pound (450 g) store-bought or homemade pizza dough
- Olive oil: 2 tablespoons
- Yellow onions: 2 large, thinly sliced
- Balsamic vinegar: 2 teaspoons
- Mushrooms: 8 ounces (225 g) cremini or button, sliced
- Garlic: 2 cloves, minced
- Fresh thyme: 1 teaspoon leaves (or 1/2 teaspoon dried)
- Salt: 1/2 teaspoon
- Black pepper: 1/4 teaspoon
- Mozzarella cheese: 1 cup (100 g), shredded
- Goat cheese or feta: 1/2 cup (50 g), crumbled
- Fresh parsley (optional): 2 tablespoons, chopped
Instructions
- Preheat Oven:
- Preheat the oven to 450°F (230°C). If using a pizza stone, place it in the oven to heat.
- Caramelize Onions:
- In a large skillet over medium heat, add 1 tablespoon olive oil and the onions. Cook, stirring occasionally, until onions are golden and caramelized, about 20 minutes. Stir in balsamic vinegar and cook 2 more minutes. Remove onions from skillet and set aside.
- Sauté Mushrooms:
- In the same skillet, add remaining 1 tablespoon olive oil. Add mushrooms and cook until softened and golden, about 6–8 minutes. Add garlic, thyme, salt, and pepper; cook for 1 minute. Remove from heat.
- Prepare Dough:
- On a lightly floured surface, roll out the dough into a 12x8-inch (30x20 cm) rectangle or oval. Transfer to a parchment-lined baking sheet or preheated pizza stone.
- Assemble Flatbread:
- Evenly spread the caramelized onions over the dough. Top with mushrooms, then sprinkle with mozzarella and goat cheese (or feta).
- Bake:
- Bake for 12–15 minutes, until the crust is golden and the cheese is bubbly and lightly browned.
- Finish & Serve:
- Remove from oven, sprinkle with fresh parsley if desired, slice, and serve warm.

Recipe FAQ
- → How do I caramelize onions properly?
Cook thinly sliced onions slowly over medium heat with oil until they turn golden brown and sweet, stirring occasionally to prevent burning. This process typically takes about 20 minutes.
- → Can I use a different type of cheese?
Yes, mozzarella and goat cheese provide a nice melt and tang, but you can substitute with feta, fontina, or a cheese blend that melts well and complements onions and mushrooms.
- → What dough options work best for this flatbread?
Store-bought or homemade pizza dough both work well. For a quicker option, naan or pre-baked flatbread can be used as a base.
- → How can I make this dish vegan or gluten-free?
Use gluten-free dough alternatives and swap cheeses for plant-based vegan options to accommodate dietary restrictions.
- → What's the best way to reheat leftover flatbread?
Reheat in a preheated oven or toaster oven at moderate heat to maintain crispness, avoiding microwaves which can make the crust soggy.
- → Can additional herbs or toppings be added?
Fresh herbs like parsley or thyme enhance flavor; optional toppings such as arugula or a drizzle of truffle oil add depth and freshness.
