Meatballs
- 1 lb ground beef (or 12–16 store-bought seasoned meatballs)
- 2 cloves garlic, minced
- 1 tsp fresh thyme or rosemary, chopped
- Salt and pepper, to taste
Caramelized Onions
- 3 large onions, thinly sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 1/2 cup beef broth
- Salt and pepper, to taste
Bread and Cheese
- 1 baguette or 4 hoagie rolls, sliced lengthwise
- 6–8 oz Gruyère or Swiss cheese, sliced or shredded
- Butter, for toasting bread
Optional Garnishes and Herbs
- Fresh thyme or rosemary for topping
- Chopped parsley
- Balsamic glaze (optional)
- Caramelize the Onions: Thinly slice the onions and cook slowly over medium-low heat with butter and olive oil. Stir frequently for 30–40 minutes until the onions turn golden brown and develop a sweet, rich flavor.
- Prepare or Heat the Meatballs: If making homemade, season ground beef with garlic, herbs, salt, and pepper, then shape into small meatballs and pan-fry or bake until fully cooked but still juicy. If using store-bought, warm them in a skillet or oven until heated through.
- Toast the Bread: Slice the baguette or hoagie rolls lengthwise and toast in a buttered skillet or oven until golden and crisp on the edges but soft inside, providing a sturdy base for the toppings.
- Layer Your Melts: Pile toasted bread with a generous layer of caramelized onions, top with warm meatballs, then cover with slices or shreds of Gruyère or preferred cheese to achieve a creamy, melted topping.
- Melt and Serve: Place the assembled melts under a broiler or in a hot oven for a few minutes until the cheese bubbles, melts, and slightly browns. Serve immediately while warm for the best comfort food experience.
Notes
- Caramelize onions slowly to fully develop sweetness and depth of flavor.
- Use quality melting cheeses like Gruyère or Swiss for the best taste and texture.
- Avoid overcooking meatballs to keep them juicy and tender.
- Toast bread to a golden crisp exterior with a soft interior to prevent sogginess.
- Fresh herbs add a fragrant and flavorful finishing touch.
