Cheesy Spaghetti Squash Casserole


I was tempted to call this recipe “Cheesy Hash Brown Casserole,” because it tastes ridiculously similar to the creamy hash brown casserole that my mom usually makes for our holiday brunches.

Only, this version doesn’t call for frozen hash browns. Instead, it features nutrient-rich spaghetti squash!

Cooked spaghetti squash has a surprisingly similar texture to hash browns, and blends seamlessly into this simple casserole, with a lower starch content. Combined with sauteed onions, probiotic-rich yogurt, and a bit of raw goat cheddar, this creamy dish is classic comfort food–> without leaving you feeling uncomfortable later.

Cheesy Spaghetti Squash Casserole
Serves 4-6

Adapted from this recipe

Ingredients:

1 medium spaghetti squash
1 tablespoon butter
1/2 yellow onion, chopped
1 garlic clove, minced
1 cup plain goat’s milk yogurt, or greek yogurt
3 oz. raw goat cheddar, shredded and divided
1 teaspoon sea salt, or to taste
black pepper, to taste

Directions:

Preheat the oven to 400F and line a baking sheet with a Silpat or parchment paper. Cut the spaghetti squash in half, and remove the seeds. Place the squash halves cut-side-down on the baking sheet, and cook for 35-45 minutes, or until a fork can easily pierce the outer shell. (For full directions, see this post.)

Once you have removed the squash from the oven, melt the butter in a skillet over medium-high heat and saute the chopped onion and garlic until tender and slightly golden, about 5 minutes.

Transfer the cooked onion and garlic to a large mixing bowl, and combine with the yogurt and 2 oz. of shredded goat cheddar, then season with salt and pepper. When the spaghetti squash is cool enough to handle, use a fork to scrape the noodle-like strands into the bowl, and mix well.

How on earth is all that cheese on top just 1oz. I am starring at 4 ounces of shredded cheese And this alone is just enough for the top, I would have to do 4 more for for the dish it self.

    Kelly

    I take it back, I think I envisioned using a bigger pan, it was enough. I just died and went to heaven, omg it’s sooooooo good. The cheese and yogurt together make it seem like I used ricotta even though I didnt. I just ate half the dish, I can’t stop. This is going at the top of my comfort food list. Thank you, thank you, thank you

Cheesy-Spaghetti-Squash-Casserole looks and sounds GREAT!!! I’m a very brittle diabetic and have to be strict and count all carbs. Can you tell me how to come up with the carbs according to the recipe? Thanks!

Can you prepare the spaghetti squash ahead of time and then mix it up when you’re ready? Also, what sides would you serve with this? I’m new to clean eating.

Stephanie Jacobs

Just want you to know that I LOVE this recipe, I make it all the time! I’m going to be so sad when spaghetti squash goes out of season and I can’t make it until next year. Great job!!!

Hi Megan,

What kind of meat would taste best in this if I added meat? Thanks!

    Megan Gilmore

    I’ve added chicken to it before and my family loved it!

Marianne

I have made this several times; it is so delicious and always a hit! Our garden is going crazy right now with yellow squash, so I was thinking of substituting them (in “spiralized” form) for the spaghetti squash. I was curious if anybody had tried this already and could offer any feedback on how it turned out?

Kate

Used shredded organic cheddar instead of goat- ended up tasting like a healthier/better version of Cracker Barrel’s hashbrown casserole! Did get some watery-ness at the bottom of the dish- thinking maybe my glassware was too small and would have required more time in the oven to fully cook through? Regardless- it was great!

I am going to be making this for Thanksgiving and want to know if it would work out to make it ahead of time and freeze it then bake it the day of? Would the consisting be ok or would it be weird? Thanks

    Tara

    this is late but I have frozzen it when I have made it. I halfed the amount b4 baking it. then froze it and baked it a month later. it was just a yumm-o

Aileen Sabira

This looks DELICIOUS! Any ideas on what products would make it great if one was also trying to be dairy free? THANKS!

    Megan Gilmore

    I haven’t tried a dairy-free yogurt myself, but several reviewers have mentioned using plain dairy-free yogurt with success. I’d look for a brand with no added sugar, to make sure it’s tart like sour cream.

Kelly

So, sorry for the silly question but what is a spaghetti squash? Thanks 🙂

    sheila

    It’s a squash that has strings of the squash inside that resemble spaghetti. So if you are grain free, you can still feel like you aren’t missing out.

Alison

In typical fashion I misread and made with goat cheese..not goat cheddar. Obviously was unable to grate which is when I realized my error. It’s almost done cooking. I’m sure it’ll be yummy. Looking forward to trying again with correct cheese

Tc

I just made this for the first time last night. I used greek yogurt, regular goat cheese crumbles and I added some Italian deer sausage. OMG IT WAS AMAZING! I can see this becoming a staple for me. I’ll probably make it with some chicken sausage and freeze it for breakfasts. You could change it up so many ways! I’ve tried a lot of your recipes, love them all and this was still probably the best! Thank you!

Delaina

I used natural cheddar cheese instead of goat cheese. OMG this recipe is soooo good!!

Sveta

What would be considered a medium sized spaghetti squash? Or how many cups of cooked spaghetti squash is needed for this recipe? I have some leftover after making the quiche, just wondering if I have enough to make this too.

    Megan Gilmore

    Usually my spaghetti squash are about 3 pounds– probably 2 heaping cups worth?

      Sveta

      Perfect, I have just enough left. Thank you! By the way, that crustless quiche was awesome, even my youngest daughter ate it!

Debstinydogs

I added a bit of brown sugar to mask the tang of the Greek yogurt, which hubby doesn’t care for. He loved it. Also, I put it under the broiler fo a few minutes at the end to get the top extra brown and crunchy. Delish!!

GW

I used your recipe as a springboard. I doubled it, and used regular shredded cheddar instead of goat cheddar, plus added frozen peas and two cans of tuna (drained). I also pulsed some Caesar croutons in my food processor and sprinkled the crumbs on top at the end, then popped it under the broiler until they browned.

Aileen

I had leftover spaghetti squash and was looking for a recipe to use it. This was perfect since I already had the squash baked. However I did not have plain Greek yogurt on hand so I used sour cream in a pinch and it worked great! The whole family loved it, I would definitely make this again and again! Thank you!

Lyn :]

Well I went to make this recipe and low and behold had no cheddar cheese , so I substituted with pecorino romano. Oh my Word this was soooooo delicious!!! I wish I could give it a ten rating!!! So indebted to you for my great dinners, :] Lyn :]
