Instructions
Prepare croutons
Preheat oven to 375°F (190°C). Toss bread cubes with olive oil and spread on a baking sheet.
Pro tip: Use a rimmed baking sheet to prevent croutons from falling off.
Bake croutons
Bake for 10-12 minutes until lightly golden and crispy. Remove from oven and set aside.
Pro tip: Stir croutons halfway through baking for even crispness.
Caramelize onions
In a skillet over medium heat, melt butter. Add onions and cook for 20-25 minutes, stirring occasionally, until golden brown. Add brown sugar and cook for another 5 minutes.
Pro tip: Lower heat if onions start to brown too quickly.
Assemble croutons
Spread caramelized onions over the baked croutons on the sheet pan.
Pro tip: Ensure even distribution of onions for balanced flavour.
Add cheese
Sprinkle grated cheese evenly over the onion-covered croutons.
Pro tip: For a richer flavour, mix different cheeses.
Gratinate
Return to oven and bake for another 8-10 minutes until cheese is melted and bubbly.
Pro tip: Broil for the last 2 minutes for a golden top.
Tips & Tricks
- Use day-old bread for the best texture in croutons.
