Step-by-Step Cooking Instructions
Prepping the Vegetables
-
Preheat your oven to 400°F (200°C).
-
Lightly grease a large baking dish or line it with parchment paper to prevent sticking.
-
In a large mixing bowl, combine 1 chopped zucchini, 1 red bell pepper, 1 yellow bell pepper, 1 sliced red onion, and 1 cup cherry tomatoes.
-
Add 3 tablespoons olive oil, 1 teaspoon dried Italian seasoning, salt and pepper to taste, and 2 minced garlic cloves.
-
Toss everything thoroughly to ensure the vegetables are evenly coated in oil and seasoning.
Spread the mixture in a single layer in the baking dish. Even spacing allows for proper roasting, not steaming—essential for getting that golden caramelization.
Initial Roasting
Roast for 20–25 minutes, checking halfway to stir and promote even cooking. You’ll know it’s ready when the vegetables are tender and slightly browned at the edges. The tomatoes should look wrinkled and juicy.
