Ingredients
2 slices thick-cut sourdough bread
2 tablespoons unsalted butter
1 large yellow onion, thinly sliced
1 tablespoon balsamic vinegar
1/2 teaspoon dried thyme
1 cup shredded Gruyère cheese
1/2 cup shredded mozzarella cheese
2 strips crispy turkey bacon, cooked and crumbled
Salt and black pepper to taste
Instructions
Melt 1 tablespoon of butter in a skillet over medium heat.
Add the sliced onions, a pinch of salt, and pepper to the skillet.
Cook for 15-20 minutes, stirring occasionally, until the onions are soft and deep golden brown.
Stir in the balsamic vinegar and dried thyme, cooking for 1 minute until fragrant and glossy; remove from the skillet.
Butter one side of each bread slice.
Place one slice butter-side down in the skillet.
Layer half of the cheese, the caramelized onion mixture, the crumbled turkey bacon, and the remaining cheese.
Top with the second bread slice, butter-side up.
Cook over medium-low heat for 3-4 minutes per side until the bread is golden brown and the cheese is completely melted.
Notes
Do not rush the onions; slow caramelization is essential for developing natural sweetness.
The caramelized onion mixture can be stored in the refrigerator for up to 3 days.
Pre-cook the turkey bacon ahead of time to ensure it reaches the perfect smoky crunch.
