A mix of sausage and summer squash are used in this low carb gluten free squash casserole with cheese. It's a tasty way to enjoy your garden produce.
The summer vegetables are ripening in the garden. And I needed to find an easy dish to prepare for dinner.
I had already thawed some ground sausage so I decided to mix it into a standard keto squash casserole recipe.
The result was amazing! Very tasty.
The mayonnaise gives this low carb gluten free sausage squash casserole with cheese a nice tangy flavor.
If you don't like mayonnaise, you can probably use sour cream or yogurt in its place. But, I love using healthier avocado mayo in casseroles.
I also sweetened it up a bit by adding a packet of stevia sweetener. You can leave that out if you prefer a more savory flavor.
One packet of sweetener is equal to about 2 teaspoons of sugar equivalent so feel free to use a bulk sweetener if you'd like.
The photos for this recipe were updated in February 2016, over five years after the original recipe was posted.
My food photography skills have improved greatly over that time. However, I still like how the dish came out originally.
Here's the original recipe photo:
What do you think? I believe I've come a long way since I first started this low carb blog in July 2010!
Not only have my photos improved over the years, but so has my cooking!
I openly admit that I wasn't great at cooking when I first started this blog. My skills were mainly in baking, not regular savory meals.
I have since learned a lot about food and cooking in general by tweaking and developing my low carb recipes for this blog.
A lot of my earlier recipes like this low carb gluten free sausage squash casserole haven't deserved the love they truly deserve due to the poor photos.
So I've been taking some time to make some of my older recipes and reshoot new pictures for them.
2015 was a real turning point for me and this food blog.
In January 2015, the name was changed from SugarFreeLowCarbRecipes.com to LowCarbYum.com which made it easier to promote.
The new name is shorter and easier to remember. It's also much simpler to type into a web browser!

Since there is only my husband and myself, we had to halve this recipe. It was still absolutely delicious! We will definitely make it again and again. Thank you ever so much for sharing this!
Beth Moore
I seriously not only applaud but appreciate those people who work hard to develop recipes and then take the time to write about them/photograph them or video them. You who do this for those of us who are looking for recipes deserve so much credit! I am always sad when recipes are rated with but with this or that change, because THAT is not the recipe and thus should not be rated as such. It is great that so many realize recipes are a guideline. But I want to know who prepared the dish AS WRITTEN. I think it is great that others have great ideas on how to change or improve recipes but I am really wondering why they don't do the HARD work required to develop their own social media pages. Anyhow, just my thoughts with a huge thanks for posting a recipe I looked for and appreciate!
Michelle
Absolutely delicious! This was a hit with my husband and myself!! He had bariatric surgery and can't tolerate pasta so this was perfect!! We will definitely add this recipe into the rotation!!
Isabel
I could eat this every day. I have been making your Recipe for years and I can bring it to get together sand is always gone in minutes.
Sometimes I just make it without the meat, and is still yummy ????
Thank you!!
Betsy
This was REALLY good!! Ironically, I had planned on making your sausage egg casserole with spinach that you have in your new cookbook, but I had some squash I needed to use, so when I found this recipe, I decided to make this one instead, and it was SO tasty!! The only change I made was that I didn't have any zucchini, but I had exactly 3 squash, so I just used all 3 of those instead of 2 squash and 1 zucchini. Anyway, I highly recommend this recipe, and next time I'll try the one from the cookbook. Oh, and I didn't add the sweetener - and my hubby put hot sauce on the finished product - but he puts hot sauce on everything! ????
Suzanne
This was so good!!! I used venison sausage because that's what I had on hand! Delicious! Also, I crushed just like a handful of pork rinds on the top for crunch! Thank you for this recipe! I really didn't expect it to turn out as good as it did!
Ray
I tried making this without the sausage due to Lent. Not sure if that would have helped, but mayo was a bit overpowering. I think in future attempts I'll substitute with sour cream or heavy cream.
Lisa MarcAurele
If the sausage is left out, other ingredients need to be adjusted.
Paula Coffman
Plan on making this with Italian Sausage and Mozzarella Cheese. I will probably use sour cream instead of the mayo. I had some leftover Italian sausage I wanted to use, and I did not want to go to all the trouble of making a zucchini lasagna. This will be just right!
Lisa MarcAurele
Sounds like a great idea to use what you have on hand. I'm sure it will come out delicious.
Cori
I used turkey Italian sausage and mozzarella and Parmesan cheese. Also I only grew yellow squash no zucchini so I used what I had. It came out delicious and I will make it again. I’d like to try the recipe as written next time. Thank you so much!
Tina
Yum!! I made a variation of this for dinner. I had ground turkey and zucchini. We all loved it! I am so glad I found your blog!
Lisa
Thanks for giving this old recipe a try. It's one of the hidden gems. 🙂
Aleta
I made this casserole tonight. My husband loves it! I did add some bell pepper (green, red, yellow).
Thank you for a great recipe.
Lisa
The peppers sound like a wonderful add. So glad your husband enjoyed it.
Andrea
I pinned this recipe a couple of years ago. I was worried the cooked squash would make it too watery. So, after I cooked the sausage and drained the fat I put the butter in the pan and sautéed the squash. It worked great. I used the sweetener and it definitely was not sweet. I also noticed a lot of oil on top when I pulled it out, so I dabbed it with paper towels. I'll definitely be making this again
Lisa
Thanks for sharing your experience Andrea!
Jan
So delicious! Could you tell many how much is a serving? 1 cup ? Thx I started low carb and I see carb amt but now sure how big a portion it is. Thx love this recipe . The cheese makes it greasy but I love the taste so I dont wish to remove it. Lol
Lisa
It's about a 2-3 inch square which would be roughly a cup or a little more.
Katie F.
This casserole is amazing! I made it tonight for the first time, and I am in love!! I did not precook the squash, but instead covered the casserole with foil for first 20 min of baking. I also left out sweetener. I used breakfast sausage so next time I'll have to cut back the amount of salt. I will be making this regularly! Thank you!!
Lisa
Thanks for the tip on covering so you don't have to precook!
Lana Blair
I have a similar recipe that has cottage cheese and mushroom soup in it. For your recipe, do you think I could substitute the mayo with cottage cheese? I don't like the idea of a cup of mayo in it. Thanks. (I also like your original photo better).
Lisa
It's worth a try, but you may want to add more fat.
Ren
Looks great! I didn't see the old picture in my search and worried I wouldn't be able to find this!
Lisa
I've been meaning to make this again and get it to look like the first time.
Denise
I'm disappointed. Followed the directions to the letter and I found the casserole very greasy (and I follow keto so I'm used to fats). Not enough "yum" for all the calories. Sorry. 🙁
Lisa
It may have been the cheese and or may used. They could both be decreased in the recipe.
Valerie Miller
I love your blog. I frequent it often and trust your recipes before many others. They are simple enough to tackle (grateful the crazy ingredients are kept to a minimum!), ALWAYS taste great and you have a lovely variety (tonight I made your cauli rice!). This dish looks wonderful. I appreciate all the photos...except now I'm hungry. Thanks, you're my go-to blogger for keto recipes!
Lisa
Thanks so much Valerie! It really means a lot 🙂
Adro
I like the original picture better, honestly. The second looks more like a breakfast casserole, which is delicious, but the dinner-like look of the first one caught my eye. I'm new to keto but loving it so far!
Lisa
That's why I kept the original photo. I agree, it is more appetizing. I'll try and get it to look like that again.
Lisa
Can chicken be substituted for the sausage?
Lisa
I think that would be a good sub!
Faith Joy
Yes you and substitute any meat you like it's your choice because everyone doesn't eat the same meats so the choice is totally up to you.
Angie Mobley
I noticed that the amount of fiber isn't listed. Is the carb amount listed the net carbs?
Lisa
There's less than 1g fiber. I've added it in.
Kim Hazlett
When you say a medium size squash...approximately how many cups sliced is 1 medium squash equivalent to?
Lisa
I usually get 2 cups shredded from a medium zucchini. Hope that helps.
Kim Hazlett
Yes...Thank you!
Anna
Just out of curiosity, why do you need to cook the squash and zucchini before cooking it in the oven?
Lisa
I find they are too firm if not cooked before.
Jessica
Could this be done as a freezer meal?
Lisa
You'd want to bake first and then freeze due to the egg.
Melissa Longshore
I read in the comments that you can freeze this, but if you do how long does it need to be cooked?
Lisa
I've frozen it cooked so I just reheat in the microwave or oven until serving temperature.
Melissa Williams
I made this tonight. Used Italian sausage and no sweetener. Was quite tasty!
Rochelle
Why the sweetener? Can it be omitted?
Lisa
It just adds a touch of sweetness. You can certainly leave it out.
Alison
This looks and sounds so tasty! I can't wait to give it a try! 🙂
Lisa
Enjoy! Tasty way to eat veggies.
Rachel
The recipe says to cook the squash. How?
What kind of sausage and cheese?
Lisa
I steamed the squash for only a couple minutes. You can use any shredded cheese, I used a mild cheddar. And for the sausage, it was a mild seasoned one without casing.
Michelle
Italian or breakfast sausage?
Lisa
I use a homemade venison sausage which is more like the breakfast sausage.
