4 ounces brie cheese, sliced

Fresh thyme leaves

Honey, for drizzling

Salt and pepper, to taste

Instructions

Notes

Add arugula on top for a peppery bite.

Swap brie for camembert or goat cheese for variation.

Caramelized onions can be made ahead and stored up to 4 days in the fridge.

Reheat toast in the oven at 350°F for 5–7 minutes; avoid microwaving.
