Ingredients

• 4 slices thick-sliced bread (preferably brioche or sourdough)
• 3 pieces large eggs
• 1 cup milk
• 1 cup Gruyere cheese, shredded
• 1 piece green apple, thinly sliced
• 0.5 piece red onion, thinly sliced
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 2 tablespoons maple syrup
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 0.125 teaspoon ground nutmeg (optional)
• 1 teaspoon fresh thyme (optional, for garnish)

Directions

Step 1

In a medium mixing bowl, whisk together the eggs, milk, salt, black pepper, and nutmeg (if using) until fully combined.

Step 2

Heat 1 tablespoon of butter and the olive oil in a skillet over medium heat. Add the sliced red onion and cook for 8-10 minutes, stirring occasionally, until caramelized and softened. Transfer to a small bowl and set aside.

Step 3

Reduce the heat to medium-low. In the same skillet, melt another tablespoon of butter. Dip one slice of bread into the egg mixture, ensuring both sides are thoroughly soaked but not falling apart.

Step 4

Place the soaked bread slice in the skillet. Repeat with additional slices, cooking 2-3 minutes on each side or until golden brown. Cook in batches, if necessary, and transfer cooked slices to a warm oven (200°F) to keep them hot.

Step 5

Once all slices are cooked, layer each piece with thinly sliced green apple and a sprinkle of shredded Gruyere cheese. Return the slices briefly to the skillet or place them under a broiler for 2-4 minutes to melt the cheese slightly.

Step 6

Top the French toast slices with the caramelized red onions and garnish with fresh thyme, if desired. Drizzle lightly with maple syrup and serve immediately.
