Wooden spoon

Aluminum foil

Oven

Preparation

Preheat your oven to 400°F (200°C). Lightly coat a large baking dish with cooking spray.

Wash all vegetables thoroughly under cold running water. Pat them dry with paper towels to remove excess moisture. Dry vegetables roast better and develop richer flavor.

Slice the zucchini, squash, carrots, onion, and peppers into evenly sized pieces so they cook at the same rate.

Cut broccoli and cauliflower into bite-sized florets. Halve the cherry tomatoes and mince the garlic.

Place all prepared vegetables except the spinach into a large mixing bowl.

Drizzle the olive oil over the vegetables. Sprinkle with Italian seasoning, oregano, paprika, onion powder, garlic powder, salt, black pepper, and crushed red pepper flakes if using.

Toss everything together thoroughly until every vegetable is lightly coated with the seasonings.

Fold the fresh spinach into the mixture. It may seem like a lot at first, but it will wilt significantly during baking.

Transfer all vegetables into the prepared baking dish and spread them into an even layer.

Cover the dish loosely with aluminum foil.

Bake for 30 minutes.

Remove the foil and gently stir the vegetables to promote even cooking.

Sprinkle the reduced-fat mozzarella and Parmesan evenly over the vegetables.

Return the dish to the oven uncovered for another 15 to 20 minutes until the vegetables are tender and the cheese is lightly golden.

If you prefer a deeper golden top, broil for 2 to 3 minutes while watching carefully to prevent burning.

Remove the bake from the oven and allow it to rest for about 10 minutes before serving.

Sprinkle with fresh parsley and basil immediately before serving for maximum freshness.

Serving Suggestions

Storage Instructions

Helpful Tips

Cut vegetables into similar sizes for even cooking.

Do not overcrowd the baking dish, as this may cause steaming instead of roasting.

Fresh herbs added after baking provide brighter flavor.

Use freshly grated cheese for better melting.

Do not overcook the vegetables to maintain their texture and vibrant color.

Roasting uncovered during the final stage helps caramelize the vegetables beautifully.
