If you are new around here, Peel with Zeal is known for vegetable side dish recipes. Out of season, I roast them and make them into veggie sandwiches or pair them with polenta cakes.

In the summer, I am all about maximizing flavors, like with my favorite tomato pie. Whatever the season, vegetable side dishes are my thing! And this parmesan zucchini and squash recipe is no different.

Whole zucchini and yellow squash keep well in the fridge for up to 2 weeks, making this a great side to plan later in the week.

📖Why My Recipe Works

Slicing the zucchini and squash thin is the best way to cook my favorite vegetables. Instead of big zucchini spears or fries you eliminate the slimy texture typically common with these types of veggies. You can even use slightly out-of-season produce and still get a great result.
The crunchy topping is so delicious. Even picky eaters can't resist this recipe. And the topping can be easily made gluten-free.
Mostly hands-Off - So you can prepare the rest of dinner. Truly the perfect summer side dish. Make this part of your regular meal plan!

🧾Ingredient Notes

When picking squash (or zucchini) look for smooth skin brightly colored skin with no wrinkles, they should be firm and small to medium size. Save the big guys for zucchini bread or summer squash soup.

You could also use other varieties like crookneck squash, zephyr, costata romanesco, globe, or pattypan squash.

Freshly Grated Parmesan Cheese-For a vegetarian option, try asiago or fontina cheese.
Panko Bread Crumbs- You can use regular or gluten-free bread crumbs. Coarsely ground nuts, like almonds or pecans, can be substituted.
Spices- You can skip the individual seasonings and use 2 teaspoons of Italian seasoning instead. It will have a slightly different, but still lovely flavor.

⏲️How to Make Roasted Zucchini and Squash

First off, get the oven nice and hot. Preheating to 400 F degrees. I prefer to line my rimmed baking sheet with a piece of parchment paper for easy clean-up.

Prep Yellow Squash and Zucchini

Cut both the zucchini and squash into even rounds. If you want longer pieces, slice on the diagonal. But keep the pieces flat and no thicker than a half-inch. I keep mine closer to ⅓ inch thick.

Season the Vegetables

In a mixing bowl, add the olive oil and all the herbs, spices and seasonings. Add the squash and zucchini and gently toss to coat.Spread the vegetables onto a baking sheet. They should be in a single layer with no overlap. Use an extra pan if needed.

Top and Roast

In a small bowl, mix together the bread crumbs and grated Parmesan cheese. Top each piece with a little of the cheesy topping.

spooning on the parmesan mixture onto the individual slices.

Baking time depends on the water quantity and the freshness of the produce you are using. Typically, this recipe is between 12 and 15 minutes in the oven.

I begin checking at 10 minutes. If the vegetables are close to done but the top isn't a nice golden brown, I like to turn on the broiler at a high heat for just a few minutes to crisp them up.

🥗What to Serve with Oven Roasted Zucchini and Squash

I love to pair this simple side dish with fancy meals like my lemon and herb turkey breast just as much as weeknight staples like my creamy lemon garlic chicken or french onion chicken.

It also makes a great pairing with my Greek roasted potatoes and a marinated bavette steak for a complete meal. Or oven-baked salmon since they cook at the same temperature.

If you like a dipping sauce, try red pepper crema, a classic romesco, san marzano sauce, or a simple yogurt dill sauce.

👩🏻‍🍳 Expert Tip

Resist the urge to slice the vegetables into spears. The cooking time and temperature won't be the same and the ratio of crunchy topping to roasted goodness will be off.

Notes

This recipe can be made with all yellow squash or all zucchini, try adding sliced onion rounds as an alternative.
I recommend freshly grated parmesan cheese over shelf stable parmesan cheese powder.
Asiago is the best vegetarian substitute for parmesan cheese for this specific recipe.
Leftovers can be stored in an airtight container in the fridge for up to 3 days. Wrapping them in the parchment paper they were baked on makes reheating easy.
Reheat in the oven at 300°F until warmed through, then broil for 1 minute to re-crisp the parmesan on top.

💬Frequently Asked Questions

Can you freeze roasted zucchini and squash?

While there are multiple ways to freeze uncooked or par-cooked zucchini and squashes we don't recommend freezing the roasted version of these vegetables. They will be extremely soggy when thawed out.

Can I make this recipe in advance?

While we don't recommend baking in advance you can assemble and put it back into the fridge for up to 3 hours before baking.

Can I make roasted zucchini and yellow squash in the air fryer?

You will have to work in batches, but you can make this recipe in the air fryer. Cook at 400 F degrees for 15 minutes. But I would make my air fryer zucchini and squash rather than this recipe.

What are the best substitutes for panko bread crumbs?

Chex Cereal- You can use either the rice or corn varieties. Pulse in a food processor until just broken up, about 15 seconds.
Rice Krispies- Be sure to grab the gluten-free variety. Again, pulse in the food processor until just broken, about 1-2 pulses.
Gluten-Free Cornflakes- While most brands are not gluten-free if you have one on hand they work the same as the corn Chex cereal.

This recipe is a keeper. Easy and tasty. I was looking for alternatives to yet another round of steamed veggies, and this recipe met the mark. Will try this with other veggies too!

Had great flavor! I didn’t have red pepper flakes or panko, so I substituted for chili powder and crushed almonds. It was delicious, will make again!
Reply
- crushed almonds is a great sub!

Yummy! This was a delicious recipe! Thanks for sharing it! I will definitely keep it and use it again!

I was so tired of mushy zucchini and yellow squash so I was excited when I found this recipe! We did broil it at the end for crispness and my husband and I both loved it😋
Reply
- I agree a quick broil is the way to go!

These were absolutely amazing!! I tweaked it a smidge by adding a Greek Seasoning to the oil & herbs. Thank you so much!

Wonderfully good! I had two small zucchini and three small crooknecks from my garden I needed to use up, but I had zero energy. This recipe looked so simple, and it really is tasty! I added onion powder (by mistake,) used garlic salt because I didn’t have kosher salt, and I was a little heavy handed with the red pepper flakes. I also combined the panko crumbs and Parmesan in the same bowl I had the oil and season in, just to make sure I got all of the seasoning in my dish and not left smeared around the bowl. I also took the suggestion of broiling it for a few minutes at the end. It was delicious! Next time, I think I might try half butter and half olive oil, but really the recipe is great as-is. Thank you!

I have always stood over a hot frying pan to fry squash. This was so much easier and tasted fabulous.

So delicious and easy. My husband said it is every bit as good as fried. I think it's even better with that parmesan flavor. This is a keeper recipe.

- Thanks for taking the time to leave a note!!!

These are really, really good. If you normally hate the slimy quality of sautéed zucchini and squash or just resent how bland they can taste, this recipe's for you. Only change I made was to skip the parchment and cook it using a roasting pan with a rack.
Reply
- Appreciate the lovely review!
  Reply
Is it possible to cook this in a casserole dish in the oven and then add panko and parm cheese at the end on broil?
Reply
- To be honest I am not sure. The higher sides might hold too much heat in cause the veggies to steam, but I think the risk is minimal. Might be worth a try.

Super easy, super delicious! Great way to use up summer bumper crop of zuchinni and summer squash. Thanks so much!
Reply
- Thank you for the review! Glad you enjoyed.

I made this for our church fellowship meal. I made a large pan of them and they were completely gone. Very easy and very good
