Gruyère is traditional and recommended for authentic French onion flavor, but you can also use provolone or Swiss cheese as delicious alternatives that complement the caramelized onions.

• Spread Flavor Boosters: Elevate the mayo spread by adding fresh herbs like chopped chives or parsley for an extra layer of brightness and aromatic complexity.

Keeping French Onion Burgers Fresh and Tasty

• Store leftover burgers in an airtight container for up to 3 days. Separate burger patties and caramelized onions to maintain their texture.
• Reheat burgers for 30-45 seconds on medium power. Add a splash of water to prevent drying out and maintain moisture.
