Bright ripe tomatoes layered with zucchini and yellow squash all blanketed by a generous sprinkle of nutty parmesan cheese make this bake an easy, flavor-packed way to showcase summer produce. I love how quickly this comes together on a busy weeknight or when friends drop by at the last minute.
I first tossed this together with odds and ends from the garden and my husband declared it his new favorite. Leftovers are rare around here because everyone grabs seconds as soon as it comes out of the oven.
Ingredients
- Zucchini: Choose medium small squash for tender slices and fewer seeds
- Yellow squash: Offers a buttery taste and creates color contrast with the zucchini
- Tomatoes: Go for ripe yet firm to keep tidy layers and avoid sogginess
- Parmesan cheese: Freshly shredded will melt best and give the dish that savory golden finish
- Black pepper: Enhances the sweetness of the squash and tomatoes
- Garlic powder: Packs gentle garlicky flavor evenly throughout the bake
- Onion powder: Adds a subtle earthy base without slicing fresh onions
- Italian spices: Try a balanced blend with oregano basil and thyme for comforting herby flavor
- Salt: Use sparingly if your parmesan is salty or adjust to taste
Step-by-Step Instructions
- Prep and Slice:
- Wash and dry all your vegetables. Slice zucchini, yellow squash and tomatoes into even rounds about one quarter inch thick for consistent cooking.
- Arrange the Vegetables:
- In a baking dish stand the slices upright in rows or spiral them in an alternating pattern. This helps every serving have all the layers and makes for a beautiful presentation.
- Season and Cheese:
- Sprinkle the shredded parmesan all over the veggies making sure to tuck a little cheese between layers. Dust evenly with garlic powder, onion powder, black pepper, Italian spices and a pinch of salt if using.
- Bake Until Tender:
- Place the prepared dish into a preheated oven at three hundred seventy five degrees. Bake for twenty five to thirty minutes or until the squash is just fork tender and the cheese is starting to brown.

There is something about the salty edge of parmesan paired with roasted fresh tomato that reminds me of potlucks at my grandmother’s table. I always reach for the cheesiest corners and sneak a taste before anyone else can claim it.
Storage Tips
Store leftovers covered in the refrigerator for up to three days. Reheat gently in the oven or microwave until warmed through. The flavors meld and deepen overnight making it a fantastic make-ahead.
Ingredient Substitutions
If you do not have yellow squash use all zucchini or add eggplant for a heartier bake. Fontina or mozzarella can stand in for parmesan for a milder taste. Fresh basil or thyme in place of the Italian seasonings gives a special touch without much effort.
Serving Suggestions
Serve this fresh from the oven alongside grilled chicken, fish or any simply prepared meat. As a light vegetarian meal pair with crusty bread for mopping up juices. An extra sprinkle of parmesan and black pepper just before serving makes each bite pop.
Cultural and Historical Note
Vegetable bakes like this have roots in Mediterranean cooking where summer produce is layered and slowly cooked to create soft savory sides. You will find similar recipes from Provence to Naples and every family adds their own special seasoning or cheese twist. It is a celebration of abundance and sharing.
Recipe FAQs
