Healthy Yellow Squash Casserole recipe- The BEST! « Running in a Skirt (1)

My garden just started producing an overabundance of summer yellow squash and zucchini by the bundles. I love this time of year where I can pick them out of the garden and have fresh vegetables for dinner. I like to roast and grill them but my Southern born and raised heart still loves a good casserole. Traditional Southern Yellow Squash Casserole features yummy yellow squash with not so great for you goodies like sour cream, mayonnaise, and butter crackers. It's delicious and there is a time and place where I love to eat that version. I dream of going back in time and being able to eat my Grandmothers again.

THIS version though is my total healthy makeover on the classic Southern Squash Casserole. It's the same but different and I think it would still make Grandma proud.

This Healthy Yellow Squash Casserole recipe features creamy greek yogurt and browned panko instead of the sour cream, mayo and butter crackers. I also added piles of fluffy quinoa, piles of green kale, AND some green zucchini to make this dish more of a complete healthy vegetarian meal. I promise it still tastes amazing even with the tweaks.

This Healthy Squash Casserole is basically a celebration of all things summer in your favorite glass baking dish.

This Healthy Yellow Squash Casserole recipe makes a great vegetarian meal!

This Healthy Yellow Squash Casserole recipe is all sorts of healthy goodness packed into one casserole dish. My version is great because it adds quinoa to the mix which makes the casserole more filling and much more of a meal. The end result is wonderful twist on classic comfort food in a perfectly healthy and complete vegetarian meal.

Serve this a vegetarian main course or a side dish for you favorite meat or fish. It would also be a perfect centerpiece for a southern vegetable plate.

What is squash casserole?

Yellow Squash Casserole is traditionally creamy, cheesy, and topped with buttery Ritz crackers. It's a great use of all those extra summer squash you have in the garden.

My version is LIKE that but still has those healthier ingredients that make it a meal or side dish you can feel good eating. Just look at all that quinoa and vegetables.

Ingredients in this Healthy Squash Casserole:

Don't let the ingredient list shy you away from making this recipe. The ingredients in my Healthy Squash Casserole are easy to find and this comes together in less than 20 minutes of hands-on cooking time.

  • Yellow Squash: Use traditional summer squash in this casserole. Summer squash is full of vitamin C, beta-carotene, folate and fiber.
  • Zucchini: You could easily use ALL yellow squash in this casserole but I like the combination of fresh summer squash and zucchini.
  • Curly Kale: Kale isn't a normal ingredient in squash casserole but I love adding it to mine for lots of color, flavor and vitamins. It's an easy way to add entire serving of veggies to the dish.
  • Sweet Onion: It's not a good Southern casserole without sweet onion! Get a Vidalia if you can find it.
  • Quinoa:Quinoa adds substance and protein to this casserole and makes it more of a meal.
  • Greek Yogurt:Greek Yogurt replaces the sour cream and mayonnaisein classic Squash Casserole.
  • Cheese:Cheese makes this casserole delicious! I used a combination of mozzarellaand parmesan.
  • Panko: I used panko instead of Ritz crackers in my Healthy Summer Squash Casserole recipe.
  • Egg: An egg binds everything together.
  • Garlic: Garlic adds a flavor punch!
  • Fresh Herbs: I grow fresh herbs in the summer and always have them around. This recipe calls for fresh basil and oregano. If you don't you have that, you could easily substitute 1 teaspoon of both dried basil and dried oregano.

How to Make a Healthy Squash Casserole

This cheesy Healthy Squash Casserole is well balanced with lots of vegetables! You will love the way it comes together. Here's how to make it:

  1. Preheat the oven to 400. Spray an 8 by 8 casserole dish with cooking spray.
  2. Saute the veggies. Start with the onion and then add the kale and garlic. Next up the squash and zucchini. Season with salt and pepper as you saute to bring out the flavors. Add your fresh herbs at the end. If using dried herbs, add them in the beginning.
  3. Remove the vegetables from the heat and stir in the quinoa, greek yogurt, cheese and panko. Taste and adjust your seasonings before adding the egg.
  4. Put the mixture in a casserole dish and top with the extra panko and parmesan.

If you want the casserole extra brown on top you can turn on your biler for just a few minutes until it's golden brown.

Variations and Pro Tips

I love this recipe as is BUT here are a few ways to mix it up...

  • Use just squash or zucchini especially if your garden as an overabundance of one or the other..
  • Substitute brown rice for the quinoa.
  • Use dried herbs instead of fresh. Use just 1 tablespoon of each.
  • Mix up the types of cheese you use. Sharp cheddar works great too.
  • Use spinach instead of kale.

Do you peel yellow squash?

NO! Summer yellow squash tastes great with the peel on. Just wash the squash under cool running water just before you are going to use it.

Can the casserole be reheated?

Yes! This casserole reheats well for lunches or dinner the next day.

Can it squash casserole be made ahead? Can this be a freezer meal?

This squash casserole can be made ahead! Just cook the casserole completely and let it cool. Put it in the freezer with an airtight cover. When you are ready to serve it bake it at 350 degrees for 35 to 45 minutes. That makes this dish a great freezer meal too.
