This 5-Ingredient Easy Meatloaf recipe may be short on ingredients, but it is loaded with flavor. The lack of breadcrumbs means you don't have them soaking up the juices, so the meat stays moist - and it's gluten free too! Parmesan cheese, onion, egg, ketchup, salt, and pepper are all that go into this yummy loaf of goodness!
Preheat oven to 400 degrees F. Line a loaf pan with aluminum foil for easy removal of the meatloaf after it is cooked.
Finely dice the Onion
Mix all ingredients (except the ⅓ cup Ketchup reserved for the top) together in a large bowl with a fork or with hands: beef, parmesan cheese, onion, egg, ketchup, salt, pepper.
Form a loaf in the loaf pan. Spread the remaining ⅓ cup Ketchup over the top of the meatloaf. Bake in the oven for 45 minutes.
Remove from the oven and let sit for 5 minutes. Remove from the pan, cut and serve with roast or mashed potatoes or salad. Enjoy!
