Ingredients

Ingredients –
2 tablespoons unsalted butter softened and divided
1 tablespoon olive oil
2 large yellow onions thinly sliced
½ teaspoon salt
¼ cup cooking wine
1 teaspoon fresh Thyme
8 slices country-style bread
¼ cup mayonnaise
4 slices Provolone cheese
4 ounces gruyere cheese sliced

Instructions

Add butter and olive oil to a large skillet, melt over medium-low heat.
Add onion slices and salt and cook stirring occasionally until jammy and golden brown, about 35-40 minutes.
Add cooking wine and fresh thyme, use a wooden spoon to deglaze pan and continue heating for 3-4 minutes.
Set aside and clean pan for next step.
Arrange bread slices on a flat surface, and spread mayonnaise on both sides of each slice of bread then flip over.
Divide caramelized onions evenly over 4 slices of bread.
Divide gruyere evenly over onions,.
Top gruyere with slice of provolone, then top with bread.
Heat skillet over medium heat. Cook sandwiches 3 minutes on each side, flipping carefully. You may need to cook in batches.
Cut in half and serve warm.

Notes

Cook the onions until they reach a jam-like consistency. This will remove any excess moisture and keep them from making the bread soggy.
Try baking the sandwiches in the oven instead of browning them in a skillet.
Ensure that the bread you choose is sturdy enough to stand up to the ingredients. A thick country-style bread is best.
