Some people who aren’t zucchini fans might be happy to hear it, but I’m a bit sad to say that this is probably the last zucchini recipe for summer 2017. I’m one of those people who tries to hold on to summer as long as possible, but even though I’ll probably be eating zucchini and garden tomatoes for a few more weeks, I’ve started to use the oven and I know fall foods are on the way!

And this recipe is such a total winner that it’s a good way to end the string of zucchini recipes I’ve been sharing lately! If you try it, I’m guessing you might want to make it more than once before zucchini season winds down. When I came up with the recipe, I actually just started out to update the photos for a very old recipe of roasted zucchini tossed with pesto, and originally I had used Sage-Pecan Pesto for this recipe.

But the strong flavor of sage isn’t for everyone and through the years I had made this more often with my favorite Basil Pesto with Lemon, somewhere along the way cooking inspiration struck and we ended up with this Roasted Summer Squash with Pesto and Parmesan which is absolutely a huge improvement on the original recipe.

In fact, this was so good that when I was having some friends over a few nights later I made it for that get-together, and it was definitely a hit with them too. And if you use Kirkland Basil Pesto like we did, this recipe is even easier and simple enough to make for a side dish most any night of the week!

How are you feeling about the approach of colder weather? Do you like to hang on to summer, or are you ready to move on to colder weather foods?

What is Summer Squash?

There are two kinds of squash, and the different names come from how squash was stored in the days when refrigerators weren’t available. Winter squash is the name for squashes like butternut and acorn, which have a hard skin and can be stored through the winter. Summer squash is the name for thin-skinned squash like zucchini, yellow crookneck or straightneck squash, or patty pan squash that will only keep for a few days without being refrigerated. Here’s more about Summer Squash and Winter Squash.

Roasted Summer Squash with Pesto and Parmesan

Yield 6 servings
Prep Time 10 minutes
Cook Time 15 minutes
Total Time 25 minutes

Roasted Summer Squash with Pesto and Parmesan is an ultra easy and delicious side dish option for zucchini or yellow summer squash.


  • 4 medium summer squash or zucchini, washed and cut into 1/2 inch slices
  • 2 tsp. + 2 tsp. extra virgin olive oil
  • 1 tsp. Italian Herb Blend
  • salt and fresh ground black pepper to taste
  • 1/3 cup Basil Pesto (more or less to taste; see notes)
  • 1/2 cup coarsely grated Parmesan cheese (more or less to taste)


  1. Preheat oven to 450F. Take pesto out of the fridge and measure out 1/3 cup into a small bowl and let it soften on the counter. Brush large baking sheet with 2 tsp. olive oil (or spray it if you have an olive oil sprayer.)
  2. Wash squash and cut off stem and blossom end. Cut squash into 1/2 inch slices. Arrange squash in single layer on a roasting pan. (If you have two colors, it looks nice to alternate them.) Brush the top of the squash with the other 2 tsp. olive oil and season with Italian Herb Blend (affiliate link), salt, and fresh-ground black pepper. Roast squash for 10 minutes, or until the squash is barely starting to soften when you pierce it with a fork.
  3. Remove squash from oven and turn the oven to broil, with a rack about 3-4 inches below the heat element. Brush the top of the hot squash pieces with Basil Pesto with Lemon, or Kirkland Basil Pesto and sprinkle with the coarsely-grated Parmesan cheese.
  4. Put the baking sheet under the broiler and cook for 3-4 minutes, until the cheese is melted and starting to brown. (Watch it carefully; things can easily burn under the broiler.)
  5. Serve hot. This can probably be kept in the fridge and reheated, although I haven't ever had any left to try that with. I'm guessing it's probably best freshly made.


I'd love to make this with my homemade Basil Pesto with Lemon, but if I didn't have any of that in the freezer I'd happily use my favorite Kirkland Basil Pesto.

  1. Almost-veg, hope you like it. I’m having this for lunch today.

    Garrett, you’re too funny. Yes, I bet this would make great cookies.

    Helen, so happy to hear it. The weather in Utah is perfect right now. It’s hard to go to work when the weather is this nice.

    Syrie, I think both those nuts would be great!

    Alisha, you’re welcome.

    Signe, me too. Everything is good with pesto.

    Jeanne, green beans with tapenade sound fabulous! You can make those for me when I visit London!

  2. Oh I love this idea! Definitely going to try it. Pesto is so vesatile… The other dip & veg combination that I love is steamed green beans tossed with olive tapenade – heaven!

  3. That looks so good! My family loves pesto…we could eat it by the spoonful. Can’t wait to try it!

  4. Thanks to provide us a new dish. i will try this.

  5. Gorgeous Kalyn. The colours are so vibrant. I’m going to try this with almonds or macadamias as my partner is allergic to pecans. Thanks for the recipe.

  6. That sage-pecan pesto sounds like something I must make and soon! I don’t think I use enough sage in my cooking, it’s time to do something about that! Your blog is like a ray of sunshine to me at the moment, it’s raining and cold here – the wettest September on record and we are only just over a week in!

  7. LOVE the sound of sage pecan pesto. Why if that doesn’t sound like the perfect combo for a sugar cookie, I dunno what is.

  8. Sage-Pecan Pesto – that totally grabs me. Those are two flavors I have never combined but, suddenly, they sound so perfect together.

    Farmer’s market this weekend and I’ve already got my shopping list: sage and pecans and, oh, must get a summer squash.


  9. Caroline, yes I’ve seen that method of using zucchini as “pasta” but also have not tried it yet. Let me know what you think if you try it.

    Lynda, glad to know you like the recipe.

  10. I love summer squash. When the season is very prolific, it’s always good to have another way to serve it. This one will be popular with the whole family, thanks!

  11. I love pesto but avoid pasta, so this is a great idea! On a similar note, have you seen this? I've been meaning to try it!


  12. Katerina, I loved this. I thought it was a great combination.

    Michael, glad you’re enjoying my sage adventures. I’ll have to try some sage tea too. I have plenty of sage, that’s for sure!

    Susan, the yellow squash in my garden is extra good this year too. It’s odd that the zucchini is not nearly as prolific.

    Joanna, that sounds really good!

    Valentina, yes it is yellow courgette. In the U.S. both zucchini and yellow squash are called summer squash. The yellow ones are also called “crookneck” or “straightneck” depending on whether they are curved or straight.

  13. The colours in this salad…pure sunshine.Can i confirm that what you call yellow summer squash is the yellow courgette? Or am I wrong? I have a lot of sage so your pesto will be prepared in my kitchen.

  14. How funny, I made something really similar a few days ago too! I sauteed my veggies instead of roasting them (too hot for the oven) but next time I’ll definitely try roasting. My version had an onion, a yellow squash, and 2 tomatoes, diced and sauteed in a little olive oil with salt and pepper. Then I added a can of chickpeas, turned off the heat when they were warm, and tossed it all with a few tablespoons of leftover basil pesto. It was SO GOOD! With a piece of whole-grain bread, it made a great dinner. I’m really intrigued by your sage pesto too!

  15. You know, for some reason yellow squash has been really flavorful the past couple of weeks here. I usually prefer zucchini, but this summer, it’s the yellow. I love the idea of the sage-pecan pesto too. I’m getting a bit tired of basil and parsley, so it will be a nice change.

  16. I’m lovin’ your sage kick, Kalyn. I was wandering around the web last night and came on a reference to sage tea and said to myself, why not? (Maybe I should stop talking to myself.) I steeped five small fresh leaves with a wedge of lemon and added a little honey. This may just replace my nightly chamomile fix.


  17. I really can’t get enough zucchini and summer squash and this recipe looks really great.

  18. Sara, thanks for confirming it will be good with basil pesto. I thought that sounded like a winner.

    Maria, thanks. The sunflowers are out of control in my yard.

  19. Your squash dish is beautiful!! I love the sage pesto idea. Also, great sunflower photos!

  20. I just made something similar the other night! I used yellow squash from my garden with homemade basil pesto and threw in some cherry tomatoes for good measure. I haven’t made sage pesto in ages, I’ll have to go harvest my little plant.
