This recipe is quick to prepare and a great alternative for a lower-carbohydrate, lower-calorie option in place of a potato side dish. My husband is a meat-and-potatoes kind of guy and even he loved this recipe.

Ingredient Checklist

Instructions Checklist
  • Place spaghetti squash in a covered dish and add 1/4 inch of water. Microwave for 10 to 12 minutes. Scrape insides of squash with a fork and transfer to a small bowl.

  • Heat margarine in a medium skillet over medium heat while spaghetti squash is cooking and cook onion, red pepper flakes, garlic powder, salt, and pepper until the onion is browned, 5 to 10 minutes.

  • Preheat the oven to 375 degrees F (190 degrees C). Grease a baking dish with nonstick cooking spray.

  • Mix spaghetti squash, onion mixture, sour cream, and 1/2 of the Cheddar cheese together. Transfer to the prepared baking dish and top with remaining Cheddar cheese.

  • Bake in the preheated oven for 20 to 25 minutes. Turn on broiler for the last 2 to 3 minutes and broil until gratin is golden brown on top.

Cook's Note:

This is a great way to encourage your kids to eat more vegetables, although you may want to use a touch less red pepper flakes when preparing for them to lessen the spicy heat as it does have a bit of a kick to it.

Yum! I followed the recipe exactly and it was delicious! I normally roast spaghetti squash in the oven but I used the microwave and it worked great. A nice change of pace! Read More

Hubby liked it but I didn't. I followed the directions, except for the pepper flakes. I thought the sour cream was too overpowering. Read More

I increased the recipe for a potluck: I doubled the squash, garlic powder, sour cream, and cheese. I left the margarine and pepper flake amounts as-is, and used half an onion. (I almost always reduce onion amounts.) I didn't have enough sour cream, so I used cream cheese to make up the deficit; and I used butter in place of margarine. || Even with these pantry and taste accommodations, this recipe was AMAZING, with a light, balanced flavor. It was a huge hit at the potluck, and I will definitely make it again. Thanks for sharing! Read More

Very good recipe. It's a little sweet because of the squash so I added extra salt and it was great. I will be making it again. Make sure to broil it so the cheese browns on top that makes it very flavorful! Even better as leftovers. Read More

My husband & I really liked this. I made it exactly as recipe is written except I punctured squash a few times before microwaving. BUT to the review that suggested it was a good way to sneak veggies into your kids that definitely didn t work for my two boys. It was a no-go! Read More

I have been tired of making the same old "spaghetti and meatballs" with my squash so I was looking for something different. This recipe was amazing. I doubled it because I had a lot of squash from our garden I am so glad I did. So delicious. I prepared the squash in the oven instead of the microwave because I like it seasoned and the roasted taste better. Read More
