Roasted Vegetable Meatloaf with Balsamic Glaze is an easy comfort food dinner made with beef, pork and veal packed with zucchini and sweet peppers. Because it bakes free-form on a sheet pan in about an hour, this recipe suits weeknight dinners, Sunday supper or a cozy fall family meal.
Cooking the zucchini and peppers first drives out their water, because raw vegetables would steam the loaf from the inside. Let them cool fully before they meet the meat, so the eggs do not begin to set in the bowl.
The glaze here is ketchup cut with balsamic vinegar and red pepper flakes, and it goes on before the loaf hits the oven. Grated Romano in the meat mixture adds salt and savor, which is why this version needs less seasoning than most.

kcalDiced zucchini and bell peppers cook down with garlic paste and chile flakes, then cool before joining three ground meats. Panko, Romano, eggs and herbs bind it all, and a balsamic ketchup glaze goes on before an hour in the oven.

Directions
- Heat the oven:Preheat to 425°F.
- Cook the vegetables:Heat the oil in a large sauté pan over high heat. Add the zucchini, peppers, garlic paste, ¼ teaspoon red pepper flakes, and salt and pepper to taste. Cook until almost soft, about 5 minutes, then set aside to cool.

- Rest: Remove from the oven and let rest 10 minutes before slicing.
FAQs
why bake at 425 when most meatloaf recipes use 350?
The higher heat sets the outside quickly, which matters for a free-form loaf holding a full pound of wet vegetables. It also caramelizes the balsamic glaze over the full hour in the oven rather than simply warming it through. Tent the loaf loosely with foil if the top darkens before the center reaches 160 degrees.
Why three kinds of ground meat?
Beef chuck brings the flavor, pork brings the fat and veal brings a fine texture that keeps the loaf tender. Any one of them used alone gives you a loaf that ends up either greasy, dry or bland. Many stores sell this exact blend as meatloaf mix, so you can skip buying three separate packages.
Why smash the garlic to a paste with coarse salt?
Salt crystals act as an abrasive, so they break the cloves down further than a knife or press can. The paste spreads evenly through the vegetables instead of leaving harsh bites of raw garlic behind in the loaf. Use the flat side of a chef knife and drag it across the board a few times.
Why panko rather than regular breadcrumbs?
Panko is flakier and absorbs moisture without turning pasty, which matters when the mix already carries cooked vegetables. Fine dried crumbs pack tighter and can give the finished loaf a dense, almost bready texture. Regular breadcrumbs still work if that is what you have on hand, so use about three quarters of a cup.
Can you make this ahead or freeze it?
Shape the loaf a day ahead and keep it covered in the refrigerator, then glaze it just before baking. Add fifteen minutes to the bake, since a cold loaf takes longer to reach temperature in the center. Baked and cooled slices freeze well for three months, though the raw loaf freezes poorly with wet vegetables in it.
