Parmesan baked yellow squash is a simple summer side dish of tender rounds topped with a golden, crunchy blanket of cheese and panko, baked until the edges brown and the centers turn soft and sweet.
It takes about ten minutes to prep and twenty minutes in a hot oven, and the squash that often ends up watery turns out firm, flavorful, and well browned with a few easy tricks.

Why This Parmesan Baked Yellow Squash Recipe Works
Slicing the squash into even quarter inch rounds and blotting them dry removes surface moisture. That step helps the topping brown and keeps the baking sheet from filling with liquid.
Parmesan melts into a savory crust with a nutty, salty flavor, while panko adds crunch. Together they create a topping that holds up to the soft squash underneath.
A quick trip under the broiler finishes the job, deepening the color and crisping the crumbs. Because squash cooks fast, the broiler delivers browning without drying out the centers.
Ingredients for Parmesan Baked Yellow Squash
- You need four medium yellow squash, three quarters cup of grated Parmesan, one half cup of panko, two tablespoons of olive oil, one teaspoon of Italian seasoning, one half teaspoon of garlic powder, and a quarter teaspoon each of salt and pepper.
- A large rimmed baking sheet, parchment paper, and a sharp knife are the only tools, and a mandoline helps if you want perfectly even slices.
Yellow squash. Pick small to medium squash with shiny skin and no soft spots. Larger ones contain more seeds and water, so they tend to bake up mushy.
Parmesan. Freshly grated Parmesan browns better and tastes richer than the pre grated kind. It also melts evenly across the rounds.
Panko. These airy crumbs stay crunchy in the oven because they absorb less oil. Regular breadcrumbs work, but the topping will be denser.
Olive oil. Brushing the rounds lightly helps the topping stick and promotes browning. Use just enough to make the surface glisten.
Seasonings. Italian seasoning and garlic powder add savory depth. Go easy on the salt because the cheese already supplies plenty.
How to Make Parmesan Baked Yellow Squash
1. Heat the oven. Heat the oven to 425 degrees F and line a large baking sheet with parchment paper. A hot oven browns the topping before the squash overcooks.
2. Slice the squash. Wash the squash, trim the ends, and cut into rounds about one quarter inch thick. Blot both sides with paper towels until dry.
3. Brush with oil. Arrange the rounds in one layer and brush each lightly with olive oil. Sprinkle with salt, pepper, Italian seasoning, and garlic powder.
4. Add the topping. Stir the Parmesan and panko together, then spoon the mixture over each round. Press gently so the crumbs adhere.
5. Bake until golden. Bake for about eighteen minutes, until the squash is tender and the topping is lightly golden. Check one round with a fork.
6. Broil to finish. Switch the oven to broil and cook for one to two minutes, watching closely, until deep golden. Let the squash rest for a few minutes before serving.
How to Serve Parmesan Baked Yellow Squash
Serve the squash as a side with oven baked pork tenderloin or lemon garlic chicken thighs, add roasted spaghetti squash for a vegetable plate, or pair it with air fryer broccoli for a cheesy, colorful supper.
How to Store and Reheat Parmesan Baked Yellow Squash
Cool the squash and refrigerate in a covered container for up to three days. Reheat on a baking sheet in a hot oven for about eight minutes to restore the crunch, because the microwave softens the topping. Freezing is not recommended since squash turns watery after thawing.
Tips and Variations for Parmesan Baked Yellow Squash
Salt and drain. For extra dryness, sprinkle the slices lightly with salt, rest them for ten minutes, and pat dry before topping.
Use one layer. Overlapping rounds trap steam and soften the crust, so give every slice a little space on the pan.
Add tomato. Thin tomato slices layered between squash rounds give a caprese style twist with fresh basil.
Flag the allergens. This dish contains milk from the Parmesan and wheat from the panko, so swap in gluten free crumbs when needed.
Wash the squash. Scrub the skin under cool running water before slicing so dirt never touches the flesh.
Try zucchini. Zucchini slices work in the same way, though they release a bit more water, so blot them well.
Watch the broiler. Broilers vary widely in strength, so stay at the oven and pull the pan as soon as the topping is golden.

Frequently Asked Questions About Parmesan Baked Yellow Squash
How do I keep parmesan baked yellow squash from getting soggy?
Cut even rounds, pat them dry, and bake on a hot pan in a single layer. A short broil at the end crisps the topping and evaporates leftover moisture.
Can I make parmesan baked yellow squash ahead of time?
Slice and top the rounds up to four hours early and keep them covered in the refrigerator. Bake just before serving for the crunchiest results.
What thickness works for parmesan baked yellow squash?
Rounds about one quarter inch thick bake evenly and brown well. Thicker slices stay firm longer, so add a few minutes to the bake.
Can I use an air fryer?
Yes, arrange the topped rounds in a single layer and cook at 375 degrees F for about eight minutes. Work in batches so the air can circulate.
Is the topping gluten free?
Not with regular panko. Use crushed gluten free crackers or gluten free crumbs, or skip the crumbs and rely on extra Parmesan.
