  • 2 tbsp unsalted butter For caramelizing the onions.
  • 1 tbsp olive oil For caramelizing the onions.
  • 1/2 tsp salt Helps draw out moisture from the onions.

Instructions

Caramelizing the Onions

  • Melt the butter and olive oil in a large skillet over medium heat.
  • Add the thinly sliced onions and cook for about 15-20 minutes until golden brown.
  • Sprinkle in salt and sugar (if using) and pour in the beef broth.
  • Let simmer until the liquid is absorbed.

Preparing the Meatloaf Mixture

  • In a large bowl, combine the ground beef, breadcrumbs, French onion soup mix, milk, egg, Worcestershire sauce, black pepper, and garlic powder.
  • Mix gently using your hands until just combined, avoiding overmixing.

Forming the Meatloaf

  • On parchment paper, flatten the meat mixture into a rectangular shape.
  • Spread the caramelized onion mixture evenly over the center.
  • Roll the meatloaf into a log shape, sealing the edges tightly.

Cooking in the Crockpot

  • Lightly grease the crockpot and place the formed meatloaf inside.
  • Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours until the internal temperature reaches 160°F.

Adding Cheesy Goodness

  • About 10 minutes before serving, lay Swiss cheese slices on top of the meatloaf.
  • Cover briefly to help the cheese melt.

Serving

  • Transfer the meatloaf onto a serving platter.
  • Spoon warm beef gravy on top and sprinkle with chopped parsley.
  • Slice and serve with your favorite sides.

Notes

Use a meat thermometer to ensure the meatloaf reaches the safe internal temperature of 160°F. Don’t overcrowd the crockpot and don’t skip the caramelization process for the onions.
