Ingredients

For the Meatloaf:

• 2 lbs ground beef (80/20 blend)
• 3 large sweet onions, thinly sliced
• 2 tbsp olive oil
• 4 cloves garlic, minced
• 2 tbsp Worcestershire sauce
• 1 cup beef broth (divided)
• 2 large eggs
• 1 cup panko breadcrumbs
• 1 tbsp fresh thyme, chopped
• 1 ½ tsp salt
• 1 tsp ground black pepper
• 2 tsp Dijon mustard

For the Cheese Sauce:

• 1 cup shredded mozzarella cheese
• 1 cup shredded Gruyère cheese
• 2 tbsp butter
• 1 tbsp all-purpose flour
• ½ cup milk

 

 

Step-by-Step Instructions

1. Caramelize the Onions
Heat olive oil in a large skillet over medium heat. Add onions with a pinch of salt and cook slowly, stirring often, for 25–30 minutes until golden and caramelized. Deglaze with a splash of beef broth as needed. Stir in garlic and cook 2 minutes. Set aside half for topping.

2. Prepare the Meatloaf Mixture
Preheat oven to 375°F (190°C). In a large bowl, combine beef, panko, eggs, Worcestershire sauce, Dijon mustard, thyme, salt, pepper, and half the caramelized onions. Mix gently until combined—do not overwork.

3. Shape and Bake
Place mixture on a parchment-lined sheet and shape into a loaf. Bake uncovered 35–40 minutes.

4. Make the Cheese Sauce
Melt butter in a saucepan, stir in flour, and cook 1–2 minutes. Slowly whisk in milk and remaining broth until thickened. Remove from heat and stir in mozzarella and Gruyère until smooth.

5. Assemble and Broil
Top baked meatloaf with remaining onions and cheese sauce. Sprinkle with extra Gruyère, then broil 3–5 minutes until bubbly and golden.
