Ingredients

• 4 tablespoons Unsalted butter
• 1 large Yellow onion
• 0.5 teaspoons Salt
• 0.25 teaspoons Black pepper
• 8 slices Rustic bread (sourdough or country loaf)
• 1 cup Sharp cheddar cheese, shredded
• 1 cup Gruyère cheese, shredded
• 1 cup Mozzarella cheese, shredded
• 0.5 cup Parmesan cheese, grated
• 4 tablespoons Mayonnaise

Directions

Step 1

Peel and thinly slice the yellow onion.

Step 2

In a medium skillet, melt 2 tablespoons of butter over medium heat.

Step 3

Add the sliced onions to the pan and season with salt and black pepper.

Step 4

Cook the onions, stirring occasionally, for about 15 minutes until they are golden brown and caramelized. Remove from heat and set aside.

Step 5

Lay out all 8 slices of bread on a clean work surface.

Step 6

In a small bowl, mix all the shredded cheeses (cheddar, Gruyère, mozzarella, and Parmesan) together until evenly combined.

Step 7

Spread 1 tablespoon of mayonnaise on one side of each slice of bread.

Step 8

Flip the slices over and evenly divide the cheese mixture onto 4 of the slices, on the non-mayonnaise side.

Step 9

Top the cheese layers with the caramelized onions, distributing them evenly across the 4 slices.

Step 10

Place the remaining 4 slices of bread on top to form sandwiches, with the mayonnaise side of the bread facing outward.

Step 11

Heat a large skillet or griddle over medium-low heat and melt 1 tablespoon of butter.

Step 12

Working in batches, place the sandwiches in the skillet. Cook for 3-4 minutes on each side, pressing gently with a spatula to ensure even browning, until the bread is golden and crispy, and the cheese is melted.

Step 13

Add more butter to the skillet as needed when cooking additional sandwiches.

Step 14

Remove the sandwiches from the skillet and let them cool for 1-2 minutes before slicing.

Step 15

Serve warm and enjoy!
