How to Make Spaghetti Squash Au Gratin
-
Prepare the Squash: Place the spaghetti squash in a covered dish and add ¼ inch of water. Microwave it on high for 10 to 12 minutes until tender. Scrape the insides with a fork and transfer the strands to a small bowl.
-
Sauté the Onions: In a medium skillet, heat the light margarine over medium heat. Add the chopped onion, red pepper flakes, garlic powder, salt, and pepper. Stir and cook until the onion is beautifully browned, about 5 to 10 minutes.
-
Preheat the Oven: Set your oven to preheat at 375°F (190°C). While it’s heating, lightly grease a baking dish with nonstick cooking spray to ensure your gratin doesn’t stick.
-
Mix Ingredients: In a mixing bowl, combine the cooked spaghetti squash, sautéed onion mixture, fat-free sour cream, and half of the shredded light Cheddar cheese. Transfer this creamy blend to the prepared baking dish and spread it evenly.
-
Bake and Broil: Top the mixture with the remaining Cheddar cheese. Bake in the preheated oven for 20 to 25 minutes until bubbly. For an extra golden crust, turn on the broiler for the last 2 to 3 minutes, watching closely to avoid burning.

How to Store and Freeze Spaghetti Squash Au Gratin
Fridge: Store any leftover spaghetti squash au gratin in an airtight container for up to 3 days. Reheat in the microwave or oven, adding a splash of water to retain moisture.
Freezer: Freeze portions of the cooled gratin in airtight containers or freezer bags for up to 3 months. Thaw in the fridge overnight before reheating for best results.
Reheating: For the best texture, reheat in the oven at 350°F (175°C) for about 15-20 minutes, covered with foil to prevent drying out, or microwave for quicker service.
Wrapping: Ensure the gratin is fully cooled before packaging to avoid condensation, which can create sogginess in your leftovers.
Expert Tips for Spaghetti Squash Au Gratin
- Choose the Right Squash: Look for a firm spaghetti squash with a uniform yellow color. A heavier squash typically indicates a sweeter, better-tasting one.
- Avoid Overcooking: Microwave until just tender; overcooking can lead to mushy strands that won’t hold up in the gratin.
- Customize Flavors: Feel free to add herbs like thyme or rosemary for an aromatic twist; just be mindful not to overpower the dish’s creamy flavor.
- Watch the Broil: When broiling, stay close and monitor the cheese to prevent burning. You want a lovely golden crust, not charred cheese!
- Store Leftovers Carefully: If you have any seconds left, store in an airtight container in the fridge. Reheat gently to preserve texture and flavor in your spaghetti squash au gratin.

Spaghetti Squash Au Gratin Recipe FAQs
How do I select a ripe spaghetti squash?
Absolutely! Look for a spaghetti squash that is firm and heavy for its size, with a vibrant yellow color. Avoid any squash with dark spots or blemishes, as these can indicate over-ripeness or spoilage. A good quality squash will give a dull thud when gently tapped, which signifies ripeness.
How should I store leftover spaghetti squash au gratin?
Very simple! Just place any leftover spaghetti squash au gratin in an airtight container and store it in the refrigerator for up to 3 days. It’s best to reheat it gently in the microwave or oven with a splash of water to maintain moisture.
Can I freeze spaghetti squash au gratin?
Of course! To freeze, let your spaghetti squash au gratin cool completely. Portion it into airtight containers or freezer bags. It can be frozen for up to 3 months. When ready to use, thaw it in the fridge overnight, then reheat in the oven or microwave to enjoy.
What should I do if my spaghetti squash is too watery?
If you find your gratin is watery, it might be from excess moisture in the squash. To troubleshoot, when cooking the spaghetti squash, make sure to drain any excess water after microwaving. You can also sauté the cooked squash for a couple of minutes to evaporate excess moisture before mixing in with the other ingredients.
Are there any dietary considerations for spaghetti squash au gratin?
Definitely! This recipe is naturally gluten-free, making it a great option for those with gluten sensitivities. If there are concerns regarding dairy allergies, consider using dairy-free sour cream and cheese alternatives. It’s always great to customize recipes to fit your dietary needs while still enjoying delicious meals!
