Directions

For the Toppings:

4. In a large mixing bowl, combine the eggs, bread crumbs, parsley, ketchup, grated cheese, and ground beef. Add the cooled onions and gently mix. Be careful not to overmix!

5. Form the meat mixture into a loaf shape and place it into a large cast iron skillet lined with parchment paper.

6. Spread the caramelized onion topping over the formed meatloaf, then smooth the ketchup mixture on top of the onions. Finish with the grated cheese.

FAQs

Can I make this meatloaf ahead of time?

Yes, you can prepare the meatloaf mixture the night before and refrigerate it. Add the topping and bake it the next day.

How do I know when the meatloaf is cooked through?

Use a meat thermometer to check the internal temperature of the meatloaf. It should reach 160°F (71°C) for ground beef.

Can I freeze this meatloaf?

Yes, you can freeze the unbaked meatloaf or leftover cooked meatloaf. Wrap it tightly in plastic wrap and foil for up to 2-3 months. Reheat in the oven when ready to serve.

What kind of bread crumbs should I use?

Plain or flavored bread crumbs will both work, but plain breadcrumbs will allow the flavors of the meatloaf and toppings to shine through.

Can I use other onions instead of sweet onions?

Yes, you can use yellow onions or red onions, but sweet onions will give the meatloaf a more balanced sweetness.

Can I make this recipe in a loaf pan?

Yes, you can use a standard loaf pan instead of a cast iron skillet if you prefer. Just be sure to line the pan with parchment paper for easy removal.

How long should I let the meatloaf rest before slicing?

Allow the meatloaf to rest for about 10 minutes to set the juices and make it easier to slice.

Can I use store-bought caramelized onions?

Yes, you can use store-bought caramelized onions for convenience if you’re short on time, though homemade will always provide more flavor.

How do I make the meatloaf more moist?

If the mixture feels dry, add a little more ketchup or even some milk to the meatloaf mixture to keep it moist.
