Directions

1. Prepare the beefloaf base: In a large bowl, combine the ground beef, breadcrumbs, grated Parmesan cheese, whole milk, eggs, Worcestershire sauce, salt, and black pepper. Mix everything together gently until well combined.
2. Form the meatloaf: Shape the beef mixture into a loaf shape and place it into the bottom of your Crockpot. It should fit comfortably without overcrowding.
3. Prepare the onions: Slice the yellow onions thinly. In a skillet, melt the butter over medium heat and add the onions. Sauté the onions, stirring occasionally, for about 15-20 minutes until they become golden brown and caramelized.
4. Add the broth: Once the onions are caramelized, pour in the beef broth and stir to combine. Let the mixture simmer for 3-4 minutes, allowing the flavors to meld together.
5. Top the meatloaf: Pour the caramelized onion and broth mixture over the top of the meatloaf in the Crockpot, making sure the meatloaf is covered with the onions and liquid.
6. Cook in the Crockpot: Cover the Crockpot and cook on low for 6-8 hours, or until the meatloaf is cooked through and reaches an internal temperature of 160°F (71°C).
7. Add the Swiss cheese: About 10 minutes before serving, place the slices of Swiss cheese over the top of the meatloaf. Cover the Crockpot and cook until the cheese has melted and is bubbly.
8. Serve: Carefully remove the meatloaf from the Crockpot and slice it into portions. Serve with the caramelized onions and melted cheese on top. Enjoy!

FAQs

Can I cook this meatloaf on high in the Crockpot?

Yes, you can cook it on high for 3-4 hours instead of low for 6-8 hours. Just be sure to check the internal temperature to ensure it reaches 160°F (71°C).

Can I use a different type of cheese?

Yes, while Swiss cheese is traditional, you can substitute it with Gruyère, provolone, mozzarella, or even cheddar cheese for a different flavor profile.

Can I make the meatloaf ahead of time?

Yes, you can prepare the meatloaf ahead of time and store it in the refrigerator until you’re ready to cook it in the Crockpot. You can also prep the caramelized onions and keep them refrigerated until use.

Can I make this recipe without a Crockpot?

Yes, you can bake the meatloaf in the oven instead. Preheat the oven to 350°F (175°C) and bake for about 1 hour, or until the meatloaf reaches an internal temperature of 160°F (71°C). Top with cheese and return to the oven for 5-10 minutes to melt the cheese.

How do I know when the meatloaf is done?

The meatloaf is done when it reaches an internal temperature of 160°F (71°C) as measured by a meat thermometer. The juices should also run clear when pierced with a knife.

Can I use lean ground beef for this recipe?

You can use lean ground beef, but it may result in a slightly drier meatloaf. For a juicier texture, it’s best to use ground beef with a higher fat content, like 80/20.

Can I add vegetables to the meatloaf mixture?

Yes, you can add finely chopped vegetables like bell peppers, carrots, or mushrooms to the meatloaf mixture for added flavor and nutrition.

Can I freeze the meatloaf?

Yes, you can freeze the cooked meatloaf (without the cheese topping). Let it cool completely, then wrap it tightly in plastic wrap or aluminum foil and freeze for up to 2-3 months. Reheat in the oven at 350°F (175°C) until warmed through.

Can I use a different broth?

If you don’t have beef broth, you can substitute with chicken broth or vegetable broth for a different flavor.

How can I make this meatloaf spicier?

Add some hot sauce, red pepper flakes, or diced jalapeños to the meatloaf mixture for a spicy kick.
