Prepare the meatloaf:

Finely dice one small onion, and green pepper then cook in the Instant Pot on the saute function or on the stove until softened in a medium pan or about 5 minutes. If you don't have small ones then you can do half each of a large onion or green pepper. Salt and pepper to taste. Set aside once done to cool slightly.

Place in a large bowl about a pound or so of ground beef. For my Meatloaf with Italian Roasted Vegetables I like to use an 80/20 mixture of ground beef. This mixture ensures enough fat content for flavor and moistness without turning out a dry or greasy meatloaf.

Add to the ground beef the ground mustard, black pepper, white pepper, Worcestershire sauce, garlic powder, cayenne pepper, seasoned salt, ⅓ cup of ketchup, breadcrumbs, Parmesan cheese, egg, and the cooked vegetables.

Mix all of this together until it is well combined. Personally, I like to use a Parmesan-Romano blend of cheese but plain Parmesan will work fine. Fresh grated cheese can be used for this recipe, but I used the good old cheap kind. 😉

Form the meatloaf mixture into a loaf. It won't be long before you're enjoying this Meatloaf with Italian Roasted Vegetables! It just so happened that I could easily do this in my bowl. The meatloaf can be prepped ahead to this point wrapped tightly in plastic then cooked the next day if you like.

Place the meatloaf onto a sheet of aluminum foil then curl up the sides so the meatloaf kind of sits in an oblong bowl. It kind of reminds me of the little paper ships I used to make as kid. LOL This meatloaf measured out to be about 9-inches long so this yielded about 8 one-slices of meatloaf.

Prep the vegetables for the meatloaf

In the Instant Pot or oven proof baking pan place your potatoes, carrots, chicken broth, and Italian seasoning packet in then toss gently to coat. Place your meatloaf into the Instant Pot or Pan leaving the top of the meatloaf uncovered.

Cook the meatloaf and add the topping

To cook in the Instant Pot seal the lid and cook on high pressure for 18 minutes. To cook in the oven preheat the oven to 375-degrees then cook for one hour or until done.

While waiting for the meatloaf to cook make the topping by combining the remaining ketchup, mustard, and dark brown sugar. Once the meatloaf is cook remove from Instant Pot or oven then pour the topping on top then broil for 6 minutes.
