Kitchen Equipment Needed

Large skillet (for caramelizing onions)
Mixing bowl
Loaf pan or baking sheet
Aluminum foil (optional for covering)
Small whisk or spoon
Measuring cups and spoons

Ingredients Overview

Ground Beef: A mix of 80-85% lean ground beef works best for juicy meatloaf with good structure.
Caramelized Onions: These add sweetness and depth. Taking the time to cook the onions properly makes all the difference.
Cheese: Gruyère or Swiss cheese is recommended for its rich flavor that complements the onions.
French Onion Seasoning Mix: This seasoning blend infuses the meatloaf with the distinctive savory taste of French onion soup.

Step-by-Step Instructions

Caramelize the Onions: In a large skillet, melt butter over medium heat. Add thinly sliced onions and cook for 20-25 minutes, stirring occasionally, until golden brown and caramelized. Set aside to cool slightly.
Preheat Oven: Preheat your oven to 375°F (190°C).
Mix the Meatloaf Ingredients: In a large mixing bowl, combine the ground beef, half of the caramelized onions, French onion seasoning mix, breadcrumbs, egg, and a portion of shredded cheese. Mix until just combined, being careful not to overwork the meat.
Form and Bake: Shape the meat mixture into a loaf and place it on a parchment-lined baking sheet or in a loaf pan. Bake for 40-45 minutes or until the internal temperature reaches 160°F (71°C).
Top with Cheese and Onions: Remove the meatloaf from the oven and top with the remaining caramelized onions and shredded cheese. Return to the oven for 5-7 minutes or until the cheese is melted and bubbly.
Rest and Serve: Let the meatloaf rest for about 10 minutes before slicing. Garnish with fresh parsley if desired.

Recipe Tips

Choose the Right Ground Beef: An 80-85% lean beef balance creates a juicy meatloaf that holds together well.
Caramelize the Onions Slowly: Low and slow cooking allows the onions to release their natural sweetness.
Avoid Overmixing: Overmixing the meat can make the meatloaf dense. Mix just until combined.
