Ingredients

1 loaf French bread or Italian bread (about 16 inches)
½ cup (1 stick) unsalted butter, softened
2 tablespoons olive oil
4 cloves garlic, minced
1 large onion, thinly sliced (about 2 cups)
1 teaspoon salt
½ teaspoon black pepper
1½ cups shredded mozzarella or provolone cheese
½ cup grated Parmesan cheese
Fresh parsley for garnish (optional)

Directions

1. Caramelize the onions. In a large skillet over medium heat, heat the olive oil. Add the sliced onions and salt. Cook, stirring occasionally, for 15-20 minutes, until the onions are soft, golden brown, and caramelized. Stir in the minced garlic and cook for 1-2 minutes more until fragrant. Remove from heat.

2. Preheat and prepare. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

3. Prepare the bread. Slice the French bread in half lengthwise and place both halves cut-side up on the prepared baking sheet.

4. Spread the butter. Spread the softened butter evenly over the cut sides of the bread.

5. Add the onions. Spoon the caramelized onion and garlic mixture evenly over the buttered bread.

6. Top with cheese. Sprinkle the mozzarella cheese evenly over the onions, then top with Parmesan cheese.

7. Bake. Bake for 10-15 minutes, until the cheese is melted, bubbly, and golden brown. For an extra crispy top, broil for 1-2 minutes at the end.

8. Serve. Let cool for a few minutes, then sprinkle with fresh parsley if desired. Slice and serve warm.

Expert Tips

Caramelize slowly. Low and slow gives you sweet, golden onions.
Don’t rush the onions. They need time to develop flavor.
Use fresh bread. Day-old bread works too, but fresh is best.
Broil for crispiness. A quick broil gives you that golden, bubbly top.
Serve immediately. This is best enjoyed hot and fresh.
