Description

To understand Cannoli Dip with Cinnamon Sugar Chips, it helps to understand the roots of cannoli itself. Cannoli originated in Sicily, where they were traditionally prepared during celebrations and festivals. The classic cannoli consists of a fried pastry shell filled with sweetened ricotta, often enhanced with citrus zest, chocolate, or nuts.


Ingredients

Scale
  • 2 large sweet or yellow onions, sliced into ½-inch rounds

  • 2 tbsp butter

  • 1 tbsp olive oil

  • 1 tbsp balsamic vinegar

  • 1 tsp fresh thyme (or ½ tsp dried)

  • 1 sheet frozen puff pastry, thawed

  • ½ cup cheese (gruyère, goat cheese, feta, or sharp cheddar)

  • Salt & black pepper, to taste

  • Optional add-ins: garlic cloves, rosemary, honey drizzle


Instructions

  1. Preheat oven to 400°F (205°C).

  2. Heat butter and olive oil in an oven-safe skillet over medium heat.

  3. Arrange onion rounds in a single layer; season with salt and pepper.

  4. Cook 10–12 minutes, until golden on the bottom (don’t stir).

  5. Drizzle balsamic vinegar over onions and sprinkle with thyme.

  6. Remove skillet from heat and sprinkle cheese evenly over onions.

  7. Roll puff pastry slightly to fit skillet; place over onions.

  8. Tuck edges down around onions.

  9. Bake 20–25 minutes, until puffed and deeply golden.

  10. Rest 5 minutes, then carefully invert onto a plate.

  11. Garnish with herbs and serve warm.

Notes

Serve this caramelized onion tart warm for the best flavor and texture. You can add a sprinkle of fresh thyme, rosemary, or a handful of arugula on top for extra freshness. Pair it with a simple side salad or a light soup for a delightful brunch or appetizer.
