Do you have zucchini and yellow squash growing out your ears? This crispy parmesan crusted zucchini and yellow squash recipe is possibly the easiest summer side dish of all time, and a great way to use up garden veggies! I have a hard time not eating the entire batch single-handedly. Originally published on August 16, 2016.

Tonight Eric took Charlotte out on a Daddy-daughter date. She counted down the hours from the minute she woke up this morning until they left at 6pm. They also got married last week sometime, so I feel like I should be getting jealous here pretty soon.

You tell me who makes the better couple. I can’t decide.

I was “the roommate” during the dating scenes leading up to the blessed event. (Their courtship sounded suspiciously like mine and Eric’s.) Truman was the marriage officiator. You can send wedding gifts to…just kidding.

So how is your garden growing this summer? Did you plant one? We did, but pretty late. It’s not the end of the world since we’re in California, but our zucchini and yellow squash are still just little babes. I still wanted to try out this recipe though, ever since I saw my sister-in-law make it a few weeks ago. She got the idea from our cousin Lani, who is an amazing and intuitive cook. (She’s the one who inspired these Roasted Sweet Potatoes and Brussels Sprouts.)

This seems like such a “duh” recipe, but I had never tried it and it is SO GOOD! Is there anything better than a crispy parmesan crust, I ask you? I didn’t think so. Plus it’s just so easy and quick. I am the laziest when it comes to side dishes (seriously…baby carrots, anyone?) but even I can handle this one. Baked zucchini and squash for the win!

Parmesan Squash and Zucchini: The Easiest Side Dish

And I really do mean easiest. This good-for-you side dish requires just a few simple ingredients and is ready in a total time of 16 minutes. Can’t beat that, right? Just enough time for you to take a quick pre-dinner nap. (Although who am I kidding. I’ll probably use that 16 minutes to break up a sibling sword fight that went south. Or to stop my two-year-old from permanent-markering the wall. C’est la vie!)

What’s the difference between summer squash and zucchini?

While zucchini and summer squash are quite similar, they do have some key differences, which makes them both great additions to this parmesan squash and zucchini recipe.

  1. Shape: Zucchini tends to be straight from top to bottom. Summer squash has a fatter, more rounded bottom. Like a zucchini, but with apple bottom jeans on.
  2. Color: Zucchini is green. Summer squash, or yellow squash, is bright yellow of course! All the color is the best part of summer veggies.

Flavor: The two squashes are similar in flavor, but they are subtly different. Yellow squash has a sweeter, smoother, more buttery flavor while zucchini is richer and slightly more bitter, but in a good way.

Do you cook zucchini with the skin on?

Yes! Although you can peel it if you prefer, there’s really no need. The texture is soft and thin enough that you won’t even notice it. It’s where all the healthy stuff is too, vitamins and nutrients and stuff, so you wouldn’t want to miss that. 

Since you are leaving the skin on, remember to thoroughly wash the outside of the zucchini before slicing! 

How do you keep zucchini from getting soggy when roasting?

Zucchini has a super high water content, which means it’s naturally going to be soft. There are a couple of things you can do to make sure it isn’t soggy though:

  1. Go easy on the oil. Use just enough oil to coat the squash and zucchini, but not so much that it’s drowning in it. 
  2. Cook on high heat. 400ºF is the perfect temperature. If the heat is too low, the zucchini will become overcooked and mushy before it’s heated all the way through.
  3. Roast in a single layer. As best you can, try to spread the squash out over the pan so the slices aren’t on top of each other. We want the heat to be able to reach all around the slices to help evaporate some moisture.

Tips for Parmesan Zucchini

  • Slice larger or smaller. I usually slice the squash and zucchini into ⅛ inch rounds, but feel free to cut those rounds in half if you are a small-bite person. Totally up to you!
  • Shred your own cheese. The flavor and texture is just better. But come on, sometimes you just gotta git er done! Pre shredded cheese works fine.
  • Broil on the top rack. Moving the pan closer to the heat gives the cheese those perfect brown crispy spots. YAS.
  • Watch closely! The cheese needs just 2-3 minutes to melt over the squash, so don’t walk away and keep a close eye on it. Can’t tell you how many things I have literally set on fire in my broiler 😂

What to Serve with Parmesan Yellow Squash

This parmesan zucchini and squash recipe is about as summer-y as it gets, and it’s insanely versatile, so I love to serve it next to all the summer meals. 

It would be delicious next to a scoop of Tomato Basil Summer Veggie Casserole, BBQ Smoked Pulled Pork Sandwiches, Slow Cooker Mac and Cheese, you name it! 

Storing & Reheating Baked Parmesan Zucchini

Parmesan Crusted Zucchini and Yellow Squash is best right away, but any leftovers will last in an airtight container in the fridge for up to 4 days.

To reheat, warm in the oven at 400 until hot. Or microwave for a minute. Keep in mind that the texture won’t be quite the same as freshly roasted!

Do you have zucchini and yellow squash growing out your ears? This crispy parmesan crusted zucchini and yellow squash recipe is possibly the easiest summer side dish of all time, and a great way to use up garden veggies! I have a hard time not eating the entire batch single-handedly.


  • 2 small zucchini
  • 2 small yellow squash
  • 3 tablespoons olive oil
  • 3/4 teaspoon salt
  • cracked pepper, fresh, to taste, I like lots!
  • 1/2 cup Parmesan cheese, grated


  • Preheat your oven to 400 degrees F. Line a large rimmed baking sheet with foil for easy cleanup. (You can skip the foil if you want)
  • Slice the zucchini and yellow squash into 1/8 inch rounds. You can half the rounds if you are a small-bite person, totally up to you.
  • Add the sliced squash to a large bowl, and add olive oil, salt, and pepper. Stir to coat.
  • Spread the oiled zucchini on the prepared pan. Do your best to make sure the squash are in a single layer.
  • Sprinkle the pan evenly with shredded cheese.
  • Roast at 400 for 9-10 minutes until tender.
  • Turn on your broiler and move the pan up to the very top rack. Broil on high for 2-3 minutes. Don’t walk away!
  • Check it until it is as brown and crispy as you like it.
  • Serve immediately.


Do your best to spread the veggies in a single layer on the pan, so they get nice and crisp! Reheat these in an air fryer or oven (wish I had an air fryer!), on a pan on the stove, or in the microwave (won’t get crispy).

  1. I make a version similar to this and add minced fresh garlic too. My best tip is to put all the ingredients in a zip lock bag, shake to coat, then spread the slices on a parchments lined baking pan. So good. 

  2. I want to tell you that I love zucchini and yellow squash. Two of my favorite vegetables that I look forward to in the summer. I like to saute them with onions and olive oil and a dash of salt and pepper. I’ve been known to eat them for breakfast.

    The BIG thing I want to tell you is that I make the Texas Cowboy cookies by your recipe. It has become my favorite cookie – the coconut and cornflakes add so much texture to the cookies along with the oats. I’ve always liked oatmeal cookies with choc chips but your recipe is simply GREAT! So glad I found you on your blog and tried the Texas Cowboy cookies. Delicious!

  3. I added some Brussel Sprouts – absolutely delicious. Will be making this again. Next time will add some mushrooms and bacon. Great for a KETO diet, too!

    1. Mushrooms and bacon, great idea!! Thanks for the idea Diana! And yes, perfect for Keto!!

  4. I literally just finished cooking this recipe 2 min ago. Husband isn’t home yet and that’s awful cause this turned out AMAZING! I did a silly thing and bought cucumber instead of zucchini (don’t ask), so I quickly stashed that and quartered some mushrooms to go with the yellow squash. I also decided to throw in some garlic powder during the tossing phase. Oh darlin, this is great. I’m going to use this EVERY time I roast ANY veggie. THANK YOU!!!

    1. YAY! I’m so glad you liked it Alexandra! And good idea with the mushrooms. And don’t feel dumb about grabbing a cucumber instead of a zucchini, just the other day I got parsley instead of cilantro. NOOO!!! :) Thanks for the review!!

  5. This looks delicious, Karen! I’m totally the same when it comes to side dishes – I mean, I just spent all evening making the main dish, so I’m not going to spend another hour (and 50 dishes) making a side… ;D So yes, there has been a bit of asparagus and zuchinni/squash sides this summer – you can’t beat under 15 min of prep and 15 min cook time!

  6. I told Lucas that he’s going to have to be prepared to be married to Zoella someday and he looked at me like I was insane. Hahaha. I guess I should have given him some context ;) Truman can officiate.

  7. That is too sweet that they got married!! haha Although I guess you two do make the better couple! ;) I loveee anything with zucchini and squash – this sounds awesome!

  8. There is so much zucchini around here. I’m definitely going to make this to use some of it up. Got to love zucchini and cheese!

  9. This is awesome!!! Your kids are so funny! I made a dish like this awhile back and I can attest it is YUMMY!

  10. Love the family photos you always share. So sweet! I have so much zucchini right now and this looks like the perfect cheesy way to use it up. Sometimes the simple recipes are the best!

    1. Thanks Karen! I love them too, but they are my family so I guess that’s to be expected :) If you have tons of zucchini then this is definitely the recipe for you! So easy!

  11. Kids these days…they grow up so fast! And no, there are few things better than a crispy parmesan crust. Side dish win!

  12. Wow, that is a funny story Karen! and I love the picture of Charlotte and Eric getting married. What again is your role in this happy family situration? I don’t remember . . .
