This recipe quickly became a family favorite, especially on chilly evenings when we all want something warm and satisfying. Let me show you exactly how I make it and why you’ll want to add this to your dinner rotation.

Why This Recipe Works

This slow-cooked French onion meatloaf is tender, flavorful, and topped with gooey, melted Swiss cheese. Here’s why it works so beautifully:

  • Crockpot simplicity: No need to babysit the oven — set it and forget it.
  • French onion flavor magic: Sweet caramelized onions and savory broth flavors infused into the meat.
  • Melted Swiss cheese topping: Adds that perfect creamy, cheesy finish.
  • Super juicy and tender: Slow cooking keeps the meatloaf moist and full of flavor.
  • Perfect for weeknights or Sunday dinners: Comfort food without the fuss.

Ingredients You’ll Need

(Serves 6 | Prep Time: 15 minutes | Cook Time: 5-6 hours on low)

  • 2 pounds ground beef (I like to use 85/15 for the perfect balance)
  • 1 packet French onion soup mix
  • 1 cup crushed Ritz crackers or seasoned breadcrumbs
  • 2 large eggs
  • 1/2 cup milk
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon black pepper
  • 1/4 cup ketchup (plus extra for topping)
  • 1 cup shredded Swiss cheese
  • Fresh parsley for garnish (optional)

How I Make Crockpot French Onion Meatloaf (Step-by-Step)

1. Mix the Meatloaf

In a large mixing bowl, I combine the ground beef, French onion soup mix, crushed crackers, eggs, milk, garlic powder, black pepper, and ketchup. I mix until just combined — being careful not to overwork the meat, so it stays tender.

2. Shape and Place in the Crockpot

I form the mixture into a loaf shape and place it in the crockpot. For easy cleanup and lifting, I line the crockpot with parchment paper or foil.

3. Add a Glaze

I spread a thin layer of ketchup over the top of the meatloaf, giving it that sweet and tangy finish as it cooks.

4. Slow Cook to Perfection

I cover the crockpot and cook on low for 5 to 6 hours, or until the internal temperature reaches 160°F.

5. Add the Swiss Cheese

In the last 15 minutes of cooking, I sprinkle shredded Swiss cheese over the top and let it melt into gooey perfection.

6. Rest and Slice

I carefully lift the meatloaf out and let it rest for 5 minutes before slicing. I garnish with fresh parsley and serve.

My Favorite Tips for Perfect Meatloaf

  • Don’t overmix: Mix just until combined to keep the texture light and tender.
  • Use parchment or foil in the crockpot: It makes lifting and serving so much easier.
  • Add a little broth for extra moisture: If you like, pour 1/4 cup beef broth around the loaf before cooking.
  • Let it rest before slicing: This keeps all those flavorful juices inside.
  • Customize the cheese: Swap Swiss for provolone or mozzarella if you prefer.

What I Serve with French Onion Meatloaf

This rich, savory meatloaf pairs beautifully with:

  • Creamy mashed potatoes
  • Garlic butter green beans or roasted asparagus
  • Buttery dinner rolls to soak up extra juices
  • A simple mixed greens salad with vinaigrette
  • A glass of red wine or sparkling water with lemon

FAQs (From My Kitchen to Yours)

Q: Can I make this ahead of time?
A: Yes! You can prepare the meatloaf mixture the night before, store it covered in the fridge, and cook it the next day.

Q: Can I use ground turkey or chicken?
A: Absolutely. Just make sure to check the internal temperature (165°F for poultry).

Q: Can I freeze leftovers?
A: Yes! Slice and freeze portions in airtight containers for up to 3 months. Reheat in the microwave or oven.

Q: Can I bake this instead of using a crockpot?
A: Yes! Bake at 375°F for about 45-55 minutes, then add cheese and broil for a bubbly finish.
