This Crockpot French Onion Meatloaf brings comfort food to a whole new level! It’s packed with savory onion flavors and topped with gooey melted Swiss cheese, making every bite cheesy and delicious.
Key Ingredients & Substitutions
Ground Beef: I suggest using 80/20 ground beef for the best balance of flavor and moisture. If you’re looking for lower fat options, lean ground turkey or chicken would also work, just keep an eye on the cooking time as they can dry out faster.
French Fried Onions: While store-bought adds a nice crunch, you could use crispy onions or even crushed crackers as a substitute. If you want a healthier option, try toasting some breadcrumbs in olive oil until golden.
Swiss Cheese: Swiss is my go-to for its mild flavor and melting quality. If you prefer another flavor, Gruyère or even cheddar can also be delicious, just note the taste will change slightly.
Breadcrumbs: I usually use plain breadcrumbs, but you can swap in panko for extra crunch! If gluten is a concern, gluten-free breadcrumbs or oats can also be a great choice.
How Do I Make Sure My Meatloaf Stays Moist?
A common challenge with meatloaf is keeping it moist, especially in a Crockpot. Here are some tips:
- Don’t overmix the meat mixture. Mix just until combined to avoid a dense loaf.
- Incorporate moist ingredients like eggs and milk to help keep it juicy.
- Using a mixture of meats, such as adding some pork to the ground beef, can enhance moisture and flavor.
- Keep an eye on cooking times. Don’t overcook; use a meat thermometer to ensure it’s at 160°F (71°C).
By following these tips, you’ll have a tender and flavorful meatloaf every time!

Crockpot French Onion Meatloaf with Melted Swiss Cheese
Ingredients You’ll Need:
For the Meatloaf:
- 2 lbs ground beef (preferably 80/20)
- 1 cup French fried onions (store-bought)
- 1 cup breadcrumbs
- 2 large eggs
- 1/2 cup milk
- 1 small onion, finely diced
- 1 tsp garlic powder
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp dried thyme
- 1/2 tsp Worcestershire sauce
For the Caramelized Onions:
- 3 cups sliced onions
- 2 tbsp butter
- 1 tsp sugar
- 1 cup beef broth
For the Topping:
- 6-8 slices Swiss cheese
- Fresh parsley, chopped (for garnish)
How Much Time Will You Need?
This delicious meal requires about 20-25 minutes of prep time for the onions and meatloaf, and then you’ll let the Crockpot do the work for about 6-8 hours on LOW or 3-4 hours on HIGH. Just a little patience is all you need for this amazing flavor!
Step-by-Step Instructions:
1. Prepare the Caramelized Onions:
Start by melting the butter in a skillet over medium heat. Add your sliced onions and sprinkle the sugar over them. Cook slowly, stirring occasionally, until the onions turn soft and golden brown, which takes about 20-25 minutes. Once done, add the beef broth and simmer for another 5 minutes. Remove from heat and set aside.
2. Mix the Meatloaf Base:
In a large mixing bowl, combine ground beef, French fried onions, breadcrumbs, eggs, milk, finely diced onion, garlic powder, salt, black pepper, thyme, and Worcestershire sauce. Mix everything gently until just combined – remember to avoid overmixing to keep your meatloaf tender!
3. Shape the Meatloaf:
With your hands, form the meat mixture into a loaf shape that fits comfortably within your Crockpot insert. This helps it cook evenly.
4. Add Caramelized Onions:
Take half of the caramelized onions you prepared and spoon them over the top of the uncooked meatloaf. This adds fabulous onion flavor throughout cooking!
5. Cook in the Crockpot:
Carefully place the meatloaf in the Crockpot. Cover it up and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, until the internal temperature reaches 160°F (71°C). Just sit back and let it do its thing!
6. Add Swiss Cheese:
About 15 minutes before you’re ready to serve, place the Swiss cheese slices on top of the meatloaf. Cover and let the cheese melt—it’ll create a delicious, gooey topping!
7. Serve:
Once done, carefully transfer the meatloaf to a serving dish. Spoon any remaining caramelized onions over the top and sprinkle with chopped fresh parsley. Slice and enjoy a hearty, comforting meal!

Can I Use Leaner Ground Beef?
Yes, you can use lean ground beef, like 90/10, but keep in mind that it may result in a drier meatloaf. To counteract this, you might want to add a bit more milk or an extra egg to maintain moisture.
Can I Prepare This Meatloaf Without the Crockpot?
Absolutely! You can bake it in a preheated oven at 350°F (175°C) for about 1 hour. Use a meat thermometer to ensure the internal temperature reaches 160°F (71°C).
How Do I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place slices in the microwave or heat gently in a skillet on the stove until warmed through.
Can I Freeze the Meatloaf?
Yes, you can freeze the uncooked meatloaf or leftovers! Wrap the uncooked meatloaf tightly in plastic wrap and aluminum foil, or store it in a freezer-safe container. It should stay good for up to 3 months. Thaw it in the refrigerator before cooking or reheating.
