This simple roasted squash has become my go-to side when I want something both light and bursting with flavor. The thin slices caramelize in the oven and the Parmesan turns golden and crisp, creating a dish that vanishes as soon as it hits the table.
The first time I made this, I was in a rush on a summer weeknight and thrilled at how such little effort brought out the best in humble squash. Now it is a weekly favorite that always gets rave reviews from my family.
Ingredients
- Yellow squash or zucchini: Thinly sliced for uniform roasting Look for ones with firm skin and no soft spots for best texture
- Salt: Enhances the natural sweetness of squash and brings out the flavor Sea salt or kosher salt both work well
- Black pepper: Adds a little warmth and contrast for the cheese Use freshly cracked black pepper for more aroma
- Parmesan cheese: Freshly grated gives a crisp top and savory richness Choose real Parmigiano Reggiano if you can for the best flavor
Instructions
- Prep and Slice the Squash:
- Use a sharp knife or mandoline to cut your squash or zucchini into even thin slices about one eighth inch thick This ensures they cook at the same rate and get nicely tender
- Preheat the Oven:
- Set your oven to four hundred twenty five degrees Fahrenheit Place a rack in the center position for even heat
- Arrange the Slices:
- Line a baking sheet with parchment paper and lay the squash slices out in a single layer Slight overlap is okay but do not pile them or they will steam instead of roast
- Season Well:
- Sprinkle salt and black pepper evenly over all slices Do not skip this step as seasoning before baking draws out flavor
- Add the Parmesan:
- Scatter grated Parmesan cheese generously over the squash Cover as much surface area as possible for a crispy cheesy finish
- Roast to Golden Perfection:
- Place the baking sheet in the preheated oven Roast for fifteen minutes until the squash is tender and the cheese is bubbling and showing spots of gold Keep an eye during the last minutes to catch the cheese at its crispiest
- Serve and Enjoy:
- Let the squash cool just a minute before serving It is best enjoyed fresh and hot to experience both tenderness and crunch

My favorite part of this dish is always the cheesy bits around the edge of each slice I remember kids fighting over the most golden pieces at dinner which makes me double the batch every time now Parmesan’s nutty flavor just pairs perfectly with the sweetness of roasted squash
