步骤

Meatballs

Preheat oven to 425°. Line a large baking sheet with foil. In a large bowl, combine beef, bread crumbs, Parmesan, egg, garlic, parsley, and thyme; season with salt and pepper. Mix with your hands or a wooden spoon until well combined. Form into 16 balls (about 2 tablespoons each) and arrange on prepared sheets.

Bake meatballs until browned and cooked through, 14 to 16 minutes. Keep warm until ready to use.

Caramelized Onions

In a large skillet over medium heat, melt butter. Add onions and cook, stirring occasionally and reducing heat to medium-low after 10 minutes, until golden and jammy, about 30 minutes.

Increase heat to medium and add garlic and thyme. Cook, stirring, until fragrant, about 1 minute. Add wine, bring to a simmer, and cook until completely reduced, 2 to 3 minutes. Add broth and bring to a boil. Cook, stirring occasionally, until liquid is almost completely reduced, 8 to 10 minutes; season with salt and pepper.

Sandwiches

Heat broiler. Divide onions among hoagies. Arrange 4 meatballs in each, then top with Gruyère.

Place sandwiches on a rimmed baking sheet and broil until cheese is melty and golden (watch closely!), 2 to 5 minutes.
