  • Total Time: 4 hours 15 minutes
  • Yield: 6 servings

Ingredients

Caramelized Onions

  • 1 large onion, sliced
  • 1 tablespoon butter

Meatloaf

  • 2 pounds lean ground beef
  • 1 envelope beefy onion soup mix
  • 3/4 cup Italian bread crumbs
  • 2 eggs
  • 3/4 cup milk
  • 1 tablespoon Worcestershire sauce
  • 8 slices Swiss cheese, divided

Sauce and Garnish

  • 10.5 ounce can French onion soup
  • Parsley for garnish

Instructions

  1. Caramelize Onions: Heat a skillet over medium-high heat and add sliced onions with butter. Cook for about 10 minutes, stirring occasionally, until onions are lightly browned and caramelized. Transfer the onions to the slow cooker.
  2. Prepare Meatloaf Mixture: In a large bowl, combine ground beef, beefy onion soup mix, Italian bread crumbs, eggs, milk, and Worcestershire sauce. Dice 5 slices of Swiss cheese and mix into the meat mixture thoroughly until combined.
  3. Shape Meatloaf: Form the meat mixture into a loaf shape that will fit comfortably in your slow cooker.
  4. Assemble in Slow Cooker: Place the shaped meatloaf on top of the caramelized onions in the slow cooker. Pour the entire can of French onion soup evenly over the meatloaf.
  5. Slow Cook: Cover the slow cooker and cook on low for 4 hours or on high for 3 hours, until the meatloaf is cooked through and tender.
  6. Add Cheese Top: Five minutes before serving, arrange the remaining 3 slices of Swiss cheese on top of the meatloaf. Cover the slow cooker to allow the cheese to melt completely.
  7. Garnish and Serve: Sprinkle freshly chopped parsley over the meatloaf before slicing. Serve hot, ideally with fluffy mashed potatoes or your favorite sides.

Notes

  • For best results, cook on low for the full 4 hours to ensure the meatloaf stays moist and flavorful.
  • You can substitute the Swiss cheese with mozzarella or provolone if preferred.
  • Leftovers can be stored in an airtight container in the fridge for up to 3 days.
  • To reheat, gently warm in the microwave or oven until heated through.
  • This dish pairs wonderfully with mashed potatoes, steamed vegetables, or a simple green salad.
