I first saw this version of Parmesan-crusted squash made by my sister-in-law a few weeks ago. The idea came from a relative who’s a great, intuitive cook. It felt like one of those obvious-but-genius recipes—I had to try it.

What’s the difference between summer squash and zucchini?
Zucchini and yellow (summer) squash are similar but have small differences that affect texture and flavor.
Color: Zucchini is green; yellow squash is bright yellow—both add color to summer plates.
Flavor: Yellow squash tends to be a touch sweeter and more buttery, while zucchini has a slightly richer, more vegetal bite.
Shape: Zucchini is usually straight, while summer squash often has a wider, rounded bottom.
Ingredients for Parmesan-crusted zucchini and squash
Simple pantry ingredients make this dish fast and flavorful. The essentials:
- Parmesan cheese (grated)
- Zucchini
- Yellow squash
- Olive oil
- Salt and pepper
How to make Parmesan squash and zucchini
This is truly a fuss-free recipe.
Start by lining a baking sheet with foil for easy cleanup. Slice the squash into thin rounds—about 1/8-inch thick works well.

Toss the slices with olive oil, salt, and pepper, then arrange them in a single layer on the prepared pan. Scatter grated Parmesan over the top and roast at 400°F for about 10 minutes, until the squash is tender. For a golden, crisp finish, move the pan to the top rack and broil 2–3 minutes—watch closely to avoid burning.

Do you cook zucchini with the skin on?
Yes. The skin is thin and becomes tender when cooked, and it contains valuable nutrients. Just be sure to wash the outside thoroughly before slicing.
How do you keep zucchini from getting soggy when roasting?
Zucchini has high water content, but you can keep it crisp by following a few simple tips:
- Use only enough oil to lightly coat the slices.
- Roast at a high temperature (about 400°F) so the squash browns before getting mushy.
- Arrange the slices in a single layer so hot air can circulate and moisture can evaporate.
Tips and substitutions for Parmesan zucchini
- Slice thickness: 1/8-inch rounds are a good target. Halve the rounds if you prefer smaller bites.
- Freshly shredded cheese has a better texture and flavor, but pre-shredded works in a pinch.
- Substitute cheeses freely: cheddar, Gruyère, Emmental, or Grana Padano all work well.
- Add spices: Italian seasoning, garlic powder, cayenne, thyme, or parsley are great options.
- For extra browning, broil on the top rack for a couple minutes—but don’t leave the kitchen.

What to serve with Parmesan yellow squash
This Parmesan-crusted squash pairs beautifully with many summer mains. Try it alongside roasted or grilled meats, casseroles, pasta bakes, or sandwiches. It also complements vegetarian mains like tomato-basil vegetable bakes or grain bowls.
Storing & reheating baked Parmesan zucchini
Leftovers keep in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or an air fryer at 400°F until warmed through for the best texture. Microwaving is faster but will soften the crust.
