Caramelized Onion and Cranberry Flatbread


  • Author: Emma Taylor
  • Total Time: 40 minutes
  • Yield: 1 large flatbread 1x

Description

Sweet caramelized onions, tart cranberries, and nutty Gruyère cheese baked on a crisp flatbread.


Ingredients

Scale
  • 1 large flatbread or 2 individual naan breads
  • 1 tbsp olive oil (15 ml)
  • 1 large yellow onion, thinly sliced
  • 1/4 tsp salt
  • 1 tsp balsamic vinegar (5 ml)
  • 1/3 cup dried cranberries (approx. 45g)
  • 3 oz Gruyère cheese, grated (approx. 85g)
  • Freshly ground black pepper, to taste
  • Fresh thyme leaves, for garnish (optional)

Instructions

  1. Preheat your oven to 400°F (200°C). Place the flatbread on a baking sheet.
  2. Heat the olive oil in a large skillet over medium-low heat. Add the sliced onions and salt. Stir to coat the onions in oil.
  3. Cook the onions, stirring occasionally, for 25 to 30 minutes. Let them cook slowly until they are soft, sweet, and a deep golden brown color.
  4. Stir the balsamic vinegar and dried cranberries into the onions. Cook for another 1 to 2 minutes, until the vinegar has been absorbed. Remove the skillet from the heat.
  5. Spread the caramelized onion mixture evenly over the flatbread, leaving a small border around the edge.
  6. Sprinkle the grated Gruyère cheese evenly over the onions. Add a few grinds of black pepper.
  7. Bake for 8 to 10 minutes, or until the cheese is melted and bubbly and the edges of the flatbread are golden.
  8. Remove from the oven, garnish with fresh thyme leaves if you like. Let it cool for a minute before slicing and serving.

Notes

  • Patience is key for caramelizing onions. Don’t rush them with high heat, as they will burn instead of becoming sweet.
  • You can use other cheeses like fontina, white cheddar, or goat cheese instead of Gruyère.
  • Store-bought pre-baked pizza crusts or large pitas also work well as a base.
  • The caramelized onion topping can be made up to 3 days in advance and stored in the refrigerator.
