Summertime vacations are the perfect time to reestablish contact with family and nature. For us, most recently, it also meant enjoying the bounty of our garden while on the road.  We brought along our harvested zucchini (both green and yellow) to make a healthy Summer Squash Casserole.

As we camped, or “glamped,” eventually we ended up at a beach on the Oregon coast …

The casserole is not only pretty, it’s also so good for you! But wait … when you serve it, it’s a little messy. :)

BEST Summer Squash Casserole

There’s really no right or wrong way to make this–it essentially uses sliced squash in place of pasta.

One thing about camping (or “glamping“), at least for our family, is we just don’t feel the need to get to know our neighbors, or share food, like we would at home. It’s time to concentrate on each other and just relax and enjoy nature.

And we always love the fire!


It’s a magical time to sit, listen to nature, chat with the family, read, take naps and hikes, and then enjoy good food.

This year we used our new Camp Chef oven, layered the ingredients veggies, and baked the summer squash casserole covered with foil at 400, for 40 minutes.

Seriously, this is our new favorite summer recipe. I could have eaten the entire pan myself, so healthy – starch free, and full of the earth!

Super easy and delicious make for the best summer meals!

  1. I am just now getting ready to make this and I have become quite good at my own measurements for just two people …….because of your instructions and pictures I will be okay.
    Serving this with baked Salmon :)

  2. I added 1/4 cup chopped mushrooms, 1 cup pesto instead of 3/4, shredded carrots, and an extra zucchini. Ended up slicing the squash and zucchini into little circles too. The casserole was pretty soupy, but had great flavor, so i Made some quinoa and scooped the casserole on top! It let you keep all that flavor from the “soupy” stuff in the bottom of the casserole dish. So good!

  4. Hi Sandy … looks like you have a beautiful family 😊
    I haven’t made this recipe yet, but l am this weekend. The person that was asking about putting eggplant in the recipe you might want slice it up lay it on a cookie sheet sprinkle salt over the pieces let sit for a while should take out most of the liquid .. Just an idea!! 🤔

  5. Just in time for a ripening garden! Looks delish and can’t wait to try it.

  6. Would,this be concidered glutin free? I’m having a brunch and I know one person who would appreciate gf dish. Thanks.

  7. Can you leave the cheese out? Or us there something that can be used instead?

  8. Have you ever added eggplant to this as well?

  10. YUM!!!! I love using squash as a replacement for noodles in lasagna…I love a good roasted vegetable lasagna!

  11. Made this for dinner tonight, it was delicious. Thank you for posting

  12. Just had a few questions. Total of 4 cups cheese;? (I only used 2) Bake at 400 or 350? (350 at the bottom of recipe). I covered it in foil to seal. It was very soupy because of the veggies. Maybe just cover the top? Your thoughts? It was tasty.

    • 2 cups of cheese, Mary Lynn. Mine turns out different every time depending on how many veggies, etc. I added to instructions to let sit for 10 minutes before serving. It does set up a bit!

    • Sandy, thanks for the reply. Will let it sit a bit longer next time. It was very tasty and we will be making it again next week.

  13. 4 cups cheese total? (2 cups x 2 layers)?

  14. Mmmm…this looks delicious, Sandy! :)

  15. What a great way to use up summer garden veggies, I can almost taste it myself! A must make before summer ends.
