Tips & Substitutions

These roasted onions can elevate many Mediterranean recipes.

Serving Suggestions

These roasted onions are a fantastic side dish, especially alongside roasted meats. They pair beautifully with dishes like Luxembourg Salad or can be added to sandwiches for extra flavor. Consider serving them at room temperature for a delightful contrast. Drizzle with a little extra olive oil or vinegar before serving for added richness.

Storage & Reheating

Store leftover roasted onions in an airtight container in the refrigerator for up to 5 days. To reheat, place them in a skillet over medium heat with a splash of olive oil, stirring occasionally until warmed through. They can also be enjoyed cold in salads or as a topping for sandwiches.
