Gluten Free Summer Squash Casserole

I love casseroles! However, I don’t love all the junk that is usually in them. My kids even know to avoid them at pot lucks as they usually end up not feeling well after eating them. When I saw this recipe for Squash Casserole at Southern Bite, I knew that I could adapt it to be gluten free and Trim Healthy Mama friendly with out a lot of work!

Preheat your oven to 350 and grease a (Affiliate Link9X13 pan.

First things first, fry up the bacon! Yum! Remove bacon from the pan (actually, you’ll want to use a pot because you’ll be cooking the squash down later…and I’m lazy, the less pans/pots to wash, the better!) and fry the chopped onion and garlic in the grease. I like to get it nice and golden…it brings out a nice sweetness.

Now is a good time to mix up the eggs, cream cheese, cheddar cheese (minus a cup for the topping), salt and pepper mixture. Use a mixer so everything is well distributed.

While the onions and cooking, slice your squash or zucchini, thinly and set aside until the onions and garlic are done. I love this (affiliate link) mandolin for that job!

If you have one, chop up a tomato or two to throw in. (It’s summer, you probably have lots of veggies that could be tossed in!)

Next add the squash to the onion and garlic. Cook until the squash is wilted. If you have a lot of liquid in the pan, drain a bit of it so you don’t have a soggy casserole.

Add the bacon and the cheese mixture and stir. Pour into your greased pan and top with extra cheddar cheese.

Bake for about 45 minutes or until the top is a nice golden color.

Yum! This was perfect with our grilled steaks. This is an S veggie side if you are doing the Trim Healthy Mama plan.

If you really miss the bread crumb/cracker top, I’d try this recipe for flax bread and crumble it on top. It’s quick and easy to make and is gluten free.

      I’m so glad you liked it Annie! You can’t really go wrong with cheese and bacon, right? Have fun with THM! We are loving it here.

  2. could we use crushed corn flakes with butter and shredded cheese to top this? says

    Always looking for gluten free ways in a casserole. Thanks!
    could we use crushed corn flakes with butter and shredded cheese to top this?

    • Jessica says

      Yes! I’m sure that would work out just fine. ( I didn’t realize corn flakes were GF!) I’d also use corn chex in a pinch.

      • could we use crushed corn flakes with butter and shredded cheese to top this? says

        Thanks Jessica. Looked at my box, and it doesn’t say gf, although some boxes in the past did. However I found a neat little cracker at the grocery store from Nabisco and labeled gf. Delicious Rice Thins..flavored and tasty. Only problem is that they are pricey..very few in the box. But a guest must be very careful of gluten so I am using these today, crumbled and tumbled with shredded cheddar.:)

    I love it! Can’t wait to try it! Thanks for sharing at Savoring Saturdays. I’m going to feature it tonight! I hope you’ll come by and share again. :)

    We loved this! I omitted the bacon and used what cheeses I had on hand: cream cheese, cottage cheese, cheddar and Romano. Also, I had a few gluten free crackers that I crushed and sprinkled on top. Delish! Thanks.

      Hi Mary. I have not tried freeing this one. But, I have reheated leftovers on the stove in a pan on low, there should be enough liquid that it doesn’t brown.

    This casserole is absolutely fantastic! We’ve had it several times and I always endanger myself because I can’t wait long enough for it to cool before diving into it. The whole family is gathered around the oven like vultures waiting for the timer to go off. Seriously, it’s that good!
