🌿 Why Roasted Vegetables Are So Loved
Roasting has been a go-to cooking method for centuries because it does something magical: it caramelizes natural sugars in vegetables, transforming their flavor from simple to deeply satisfying. Unlike boiling or steaming, which can sometimes dilute flavor, roasting intensifies it.
- Zucchini & squash become tender but slightly crisp around the edges.
- Tomatoes release their juices, becoming jammy, sweet, and rich.
- Garlic mellows out, losing its sharpness and becoming buttery and aromatic.
- Parmesan cheese forms a golden crust that ties the dish together with a savory punch.
This simple process turns humble vegetables into a restaurant-quality dish with minimal effort.

🛒 Ingredients You’ll Need
Here’s the base recipe for Roasted Garlic-Parmesan Zucchini, Squash, and Tomatoes:
- 2 medium zucchini (sliced into ¼-inch rounds)
- 2 medium yellow squash (sliced into ¼-inch rounds)
- 2 cups cherry tomatoes (halved)
- 3 garlic cloves (minced)
- 3 tablespoons extra virgin olive oil
- ½ teaspoon salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon Italian seasoning (or a mix of dried basil, oregano, and thyme)
- ½ cup freshly grated Parmesan cheese
- Optional garnish: fresh parsley or basil
🔪 Step-by-Step Instructions
Step 1: Prep the Vegetables
Wash zucchini, squash, and tomatoes thoroughly. Slice zucchini and squash into even rounds. Halve cherry tomatoes so they release their juices while roasting.
Step 2: Toss with Seasonings
Place vegetables in a large mixing bowl. Drizzle with olive oil, then add garlic, salt, pepper, and Italian seasoning. Toss until evenly coated.
Step 3: Arrange on Baking Sheet
Line a baking sheet with parchment paper. Spread vegetables in a single layer to prevent steaming.
Step 4: Add Parmesan
Sprinkle freshly grated Parmesan evenly over the vegetables.
Step 5: Roast
Bake in a preheated oven at 400°F (200°C) for 20–25 minutes. The vegetables should be tender, the tomatoes slightly caramelized, and the Parmesan golden brown.
Step 6: Serve and Garnish
Transfer to a platter. Garnish with parsley or basil. Serve warm.
