This super easy and satisfying low carb cheesy spaghetti squash skillet will be a huge hit with the entire family! Tender strands of spaghetti squash swimming in a tangy meat sauce and loaded with stringy mozzarella cheese? What’s not to love?!?!

This is the last of my keto spaghetti squash recipe series this week and it’s the hand’s down favorite of the Hungry dudes. I loved them all, but even I can’t deny that the sheer comfort food awesomeness of this keto cheesy spaghetti squash skillet makes it a real winner!
Like all of this week’s low carb spaghetti squash recipes, this one is super easy – maybe even the easiest, since all you have to do is brown the meat, pour in the sauce and simmer for a bit and then add the cooked spaghetti squash. Top it with a massive amount of mozzarella cheese and even the most die hard pasta fans will have to admit that this cheesy spaghetti squash skillet is a contender.

I prefer to make this keto cheesy spaghetti squash skillet with my easy keto marinara sauce, but any quality jar sauce will do in a pinch – just make sure that it’s sugar free and you should be OK.
For store bought, my favorite keto friendly marinara sauce is Rao’s – it costs a little more than mainstream store brands, but is really tasty and free from all the fillers and junk that a lot of cheaper brands contain.
Up to you, those are just my recommendations!

There is a lot of controversy on the best way to cook spaghetti squash, I usually pierce mine all over and microwave them for about 12 – 15 minutes depending on how large they are. It works well for me usually, but every once in awhile I’ll get a mushy one and I’m not sure if it’s overcooked or just a hybrid less stringy squash variety that I might have bought. It’s tasty either way.
You can use whatever your preferred method of cooking is to get tender, stringy strands of spaghetti squash that successfully mimic pasta.
As a final note, this keto cheesy spaghetti squash skillet reheats well all week, making it the perfect low carb lunch option if you have access to a microwave at your work or school!

My squash turned out too firm. Like undercooked pasta. Any tips or is that just the way it is?
Liz says
Probably didn’t cook it long enough. Don’t remove from oven til a fork penetrates the skin easily.
Nikki says
I love, love, love spaghetti squash. Unfortunately my family doesn’t share my passion. But this is a great cook go to recipe!

Hi Mellissa,
I love your site SO much – amazing recipes.
This is one of my all time favorites and I make it for my non-keto family, who love it.
For myself, I was wondering if you have the total carb count available for this recipe – I do total, not net carbs and I see above you have the net carb calc so I assume you arrived at that by calc’ing with the total and fiber. If you could provide total, I would be SO very grateful.
Thanks!
Linda

Am I overcooking the squash if it is too watery. I usually end up straining cooked squash with a cheesecloth, but it destroys the noodle strands. Any suggestions?
Sarah says
I cut the squash into rings, remove the seeds, and season with salt and pepper (sometimes I drizzle a tbsp of olive oil over the rings as well). Then bake them at 400F for 40 minutes. Comes out great every time – hope this helps!

@Katie
Possibly, what i do is i cut it in half, gut out the seeds, put about an inch of water in the pan. Before i put the squash in the oven, i rub some olive oil, salt, pepper, and a little bit of garlic. Then i put the spaghetti squash face down (to let the steam cook the inside) then i put it in the oven at 375 for 35 minutes.
I take it out the oven and turn the squash halves over and let sit for 15 to 20 minutes.
I have NEVER had water squash or soggy squash following this method. If its a little too hard, maybe cook for 40-45 minutes but 35 works for me and my hubby and my hubby used to hate squash lol

This looks like a great recipe! Came across this while searching for keto-friendly food. Do you make your own spaghetti squash? How do yo do it?
Katharine says
This was my first time cooking spaghetti squash. I am a fan! It doesn’t get all soggy after a couple days, which is great.
I added a half bunch of lacinato kale because I am a weirdo who actually likes kale. :P Very tasty recipe and so easy. This is definitely going into the rotation.
Steve PIerson says
Cooked this for dinner tonight. It was a hit! NOM!NOM!NOM! Very easy and filling. Substituted pork sausage for the ground beef. I like spicy food, so I will jazz it up next time, but it is tasty as listed in the recipe
Also made the easy marinara sauce. Another winner.
Shay says
This is so easy to make…. I used what I had on hand, very versatile recipe. I had some shortly after I pulled it out of the oven , and it was yummy! But I warned it up hours later, WAY BETTER! So it’s a great left over! Thank you Melissa!
Patsy Weidenbach says
This was SO delicious!! I absolutely love this way of eating. Buying full fat meat, milk, everything, and still losing weight (8 pounds in 7 days!). I made this recipe exactly as written, but as is my usual practice, I did add a couple of things. About 1/4 cup of sliced olives and about 1/8 of a cup of cream cheese.
Question: I was not sure whether to drain off the fat from the meat, but assumed that since this is a high fat meal plan, that draining it was not necessary. It did seem like a lot of grease though, so I did drain about 1/2 of the fat. Can you clarify for me whether it should have been drained at all?
This is a definitely keeper. I am so heartened by the fact that I do not crave any of the crap foods that I was eating – sugar, bread, cereal, etc. And I fee really GREAT, too!
Thank you for your site. It is so great to have these resources when you are wondering what the heck to make to eat.
Janice says
Have ground beef thawing to make something similar. Instead of sauce, we use salsa and cheddar cheese. Delicious!
