This hearty vegetable-loaded meatloaf combines lean beef with an array of fresh veggies for a delicious and nutritious family meal. It's easy to prepare and perfect for gatherings.
Preheat the oven to 400 degrees F and apply cooking spray to a 9x5-inch loaf pan.
In a large skillet, heat the olive oil over medium heat. Add the chopped bell pepper and sweet onion, cooking until the onion becomes clear and the pepper is tender, about 5-10 minutes. Stir in the minced garlic for another minute until aromatic, then remove from heat.
In a sizable mixing bowl, combine the ground beef, bread crumbs, zucchini, carrots, eggs, salt, and pepper along with the cooked pepper mixture. Mix well using your hands.
Transfer the combined mixture into the loaf pan, ensuring it is tightly packed and shaped nicely.
Place the loaf in the oven and bake until the center is no longer pink, approximately 35-40 minutes. If using a meat thermometer, ensure it reaches at least 160 degrees F.
Once baked, spread ketchup on top of the meatloaf and return it to the oven for an additional 5 minutes until the ketchup is bubbly.
