Many years ago I used to write about food twice a week for BlogHer.com, and when I wrote about spaghetti squash that made me think about creative ways for cooking some of my own spaghetti squash from the garden. I found great-sounding spaghetti squash recipes all around the web, but the one that inspired this Spaghetti Squash and Chard Gratin was a recipe for Spaghetti Squash Gratin from a site that’s no longer online. Adding the chard was one of those “wonder how it would work?” experiments, but really liked the combination of spaghetti squash and chard in this cheesy gratin.
What ingredients do you need for this recipe?
- spaghetti squash
- Olive Oil (affiliate link)
- Rosemary Garlic Rub, or any all purpose seasoning that’s good on vegetables
- Spike Seasoning (affiliate link), or other all-purpose seasoning blend
- Dried Thyme (affiliate link)
- fresh ground black pepper to taste
- Minced Garlic (affiliate link)
- chopped chard leaves
- green onion
- sour cream
- cottage cheese curds (put the cottage cheese in a fine strainer and rinse with cold water)
- coarsely grated Parmesan cheese, divided
Spaghetti squash is an ingredient you’ll never forget after you’ve tried it once. It’s quite magical, the squash strings apart in a way that makes it look like spaghetti when it’s cooked, and it’s a mild-flavored squash that can get along well with many other flavors. I’ve been growing spaghetti squash for years, and I love to eat it when it’s green like a summer squash, but if you don’t have a garden you’ll have to settle for the ripe spaghetti squash you find in the store.
What is Chard?
Chard is a type of leafy greens that’s also called Swiss Chard, and a variety of other names! It’s one of my favorite greens to grow in the garden. Check out my Healthy Swiss Chard Recipes if you’re also a fan!
How to make Spaghetti Squash and Chard Gratin:
(Scroll down for complete printable recipe.)
- The hardest part of this recipe is cutting the spaghetti squash in half. You can cook it whole and then remove the seeds after it’s cooked, but I like to season the inside of the squash before it cooks.
- Use a big chef’s knife, cut off the stem and blossom end, then stand the squash up and carefully press down to cut in half.
- Then use the sharpest spoon you can find and scrape out the seeds and the slimy material that surrounds them. Throw that away.
- Spray the pan with non-stick spray or olive oil, then rub the cut surface of the squash with olive oil rub and some seasoning. (I used some Rosemary Garlic Rub, but any seasoning that tastes good on vegetables would work.)
- Pour a little water on the baking sheet before you put the squash in to bake, which helps prevent the bottom of the squash from burning.
- Squash is done when it strings apart in strands that look like spaghetti (if you use your imagination.)
- While the squash is cooling, chop the onion and chard. I wanted small pieces of chard so it would mix well with the spaghetti squash, so I sliced it thinly one direction, then turned the cutting board and sliced the other direction.
- Cook onion a few minutes with Spike Seasoning (affiliate link), dried thyme, and black pepper, add garlic, then add chard. It only takes a couple of minutes for the chard to go from the previous photo to this state of being about half wilted.
- It will cook more in the gratin, so turn off the heat as soon as it looks like this.
- Use a large fork to gently mix the shredded spaghetti squash and finely chopped chives or green onions into the chard.
- Combine the sour cream, drained cottage cheese curds, Parmesan, and beaten egg and gently mix it into the spaghetti squash/chard mixture.
- Press the mixture into a gratin dish and sprinkle on a bit more grated Parmesan, then bake at 400F/200C for 30-35 minutes.
- Serve hot and enjoy! This will keep in the refrigerator for quite a few days and reheats well.
Make it a Low-Carb Meal:
I think Spaghetti Squash and Chard Gratin would taste great with Greek Meatballs or Pork Tenderloin with Mustard Sauce for a low-carb dinner.

- Bake about 30-35 minutes, or until the mixture is bubbling and cheese is browned on top. Serve hot.
I used a spaghetti squash that was about 2.5 pounds.
If you don't have Spike Seasoning (affiliate link), use any all-purpose seasoning that's good on vegetables.
You could use other greens like spinach, collards, or kale instead of Chard. The cooking times might be longer for some greens.

Wondering about feta instead of cottage cheese? (Have a large amount from Costco-sheep & goat combo) What do you think? Thanking you.
I think that sounds pretty good! Of course the finished dish will be a little more tangy in flavor from the Feta but I bet it will be a nice combination with the spaghetti squash.

Why do you rinse the cottage cheese instead of using it as?
Since spaghetti squash is already kind of a wet ingredient, I just worry it will be to wet with the creamy part of the cottage cheese, but you could try without rinsing if you prefer.
