Cooking French Onion Meatloaf with Ease

Step 1: Caramelize Sweet Onions

Heat a skillet over medium flame.

Melt butter and add thinly sliced onions.

Slowly cook onions until they turn golden and jammy, stirring occasionally.

This process takes about 20-25 minutes.

Pour a splash of beef broth to enhance flavor and help onions caramelize.

Let onions cool completely after deglazing.

Step 2: Create Meatloaf Base

• Ground beef
• Breadcrumbs
• Milk
• Minced garlic
• Beaten egg
• Worcestershire sauce
• Dijon mustard
• Dried thyme
• Salt
• Black pepper

Mix ingredients thoroughly until well blended, ensuring even distribution of seasonings.

Step 3: Blend Caramelized Onions

Gently fold cooled caramelized onions and half the Gruyere cheese into meat mixture.

Use your hands or a spatula to incorporate ingredients without overworking the meat.

Step 4: Shape And Prepare Meatloaf

Transfer meat mixture to a baking dish.

Ensure even thickness for consistent cooking.

Step 5: Initial Baking

• Cheese Selection: Choose high-quality Gruyere for authentic French onion flavor, but can substitute with Swiss or provolone if needed for milder taste or budget considerations.
• Make-Ahead Friendly: Prepare meatloaf mixture and caramelized onions a day in advance to streamline cooking process and enhance flavor development.
