- 3 small zucchini, diced
- 3 red bell peppers, diced
- 2 medium-size red onions, diced
- 2 tablespoons olive oil
- 2 tablespoons chopped fresh rosemary, divided
- 2 pounds ground beef chuck (20% fat)
- 2 cups coarsely grated whole-milk mozzarella cheese (about 8 ounces)
- 1 1/2 cups panko (Japanese breadcrumbs)
- 1 cup thinly sliced fresh basil
- 1 tablespoon chopped fresh marjoram
- 1 1/2 teaspoons salt
- 1/2 teaspoon ground black pepper
- 1/2 teaspoon dried crushed red pepper
- 1 cup ketchup, divided
- 2 large eggs
- 1/4 cup dry red wine
- Mustard Mashed Potatoes
- Preheat oven to 450°F. Combine zucchini, peppers, and onions in medium bowl. Add oil and 1 tablespoon rosemary; toss to coat. Spread evenly on rimmed baking sheet; sprinkle with salt and pepper. Roast until vegetables are tender, about 25 minutes. Remove from oven; cool.
- Preheat oven to 375°F. Mix ground beef, mozzarella, panko, basil, marjoram, 1 1/2 teaspoons salt, 1/2 teaspoon pepper, dried crushed pepper, 1 tablespoon rosemary, and 1 cup roasted vegetables in large bowl. Whisk 1/2 cup ketchup, eggs, and wine in medium bowl. Add to beef mixture; stir with wooden spoon until well incorporated; spoon into 9x5x3-inch loaf pan, forming rounded top.
- Spoon 1/2 cup ketchup over top of loaf. Bake meatloaf until cooked through, juices run clear, and top is browned, about 1 hour 10 minutes. Remove pan from oven; let meatloaf rest 20 minutes.
- Rewarm remaining vegetable mixture in large nonstick skillet. Turn meatloaf out; cut into 1-inch-thick slices. Top with warm roasted vegetable mixture; serve with mashed potatoes.
- Flaky panko crumbs are the best substitute for fresh breadcrumbs in almost anything, including meatloaf. Look for them in the Asian foods section of the supermarket and at Asian markets.
