If your dinner plate needs a burst of freshness and flavor, look no further than this vibrant medley of roasted zucchini, yellow squash, and tomatoes. It’s colorful, healthy, and surprisingly crave-worthy with golden edges, melted Parmesan, and Italian herbs.


Why I Love This Recipe

This dish is a perfect example of how simple ingredients, when roasted just right, can transform into something extraordinary. The vegetables become tender with caramelized edges, the tomatoes add just the right acidity, and the Parmesan delivers that final salty-savory hit. It’s the kind of side you’ll want to make on repeat.


Ingredients

  • 1 medium zucchini, sliced into 1/4-inch rounds
  • 1 medium yellow squash, sliced into 1/4-inch rounds
  • 2–3 Roma tomatoes, sliced into 1/4-inch rounds
  • 2 tbsp olive oil
  • 1/2 tsp garlic powder
  • 1/2 tsp Italian seasoning
  • Salt and pepper, to taste
  • 1/3 cup grated Parmesan cheese
  • Fresh chopped parsley or basil, for garnish

Ingredient Notes and Substitutions

  • Zucchini & Squash: Keep slices uniform for even roasting.
  • Tomatoes: Roma tomatoes work best, but you can also use heirlooms or cherry tomatoes halved.
  • Herbs: Add fresh thyme or oregano before roasting for extra depth.
  • Dairy-Free? Use nutritional yeast instead of Parmesan for a cheesy flavor without the dairy.

How to Make It

1. Prep and Preheat

Set your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.

2. Arrange the Veggies

Lay out the zucchini, yellow squash, and tomato slices in a single layer on the baking sheet. Drizzle with olive oil and sprinkle with garlic powder, Italian seasoning, salt, and pepper.

3. Roast to Perfection

Roast for 20–25 minutes, flipping halfway through. You’re looking for tender veggies with golden-brown edges.

4. Add the Cheese

Sprinkle Parmesan over the roasted vegetables and return to the oven for 2–3 minutes, just until the cheese is melted and slightly crisp.

5. Garnish and Serve

Top with freshly chopped parsley or basil and serve warm.


Tips for Success

  • Don’t overcrowd the pan—use two sheets if needed so the veggies roast instead of steam.
  • Slice consistently to ensure even cooking.
  • Watch the tomatoes near the end; they can soften quickly and burst.
