Preparing Spaghetti Squash Au Gratin
Preparing Spaghetti Squash Au Gratin is a delightful culinary adventure that adds a nutritious twist to your dinner table. This dish is not only low in carbs but is also packed with flavor. Let’s break down each step to ensure your result is perfection on a plate.
Microwave the Spaghetti Squash
To start off, you’ll want to cook the spaghetti squash swiftly. Place the halved and seeded spaghetti squash in a covered microwave-safe dish with about ¼ inch of water. Cover it with a lid or plastic wrap. Microwave it on high for 10 to 12 minutes. The squash may seem intimidating, but don’t worry! This method cooks it quickly while ensuring it maintains moisture. Once cooked, the inside should easily scrape out into tender strands using a fork, which you’ll transfer to a bowl for later use. For additional tips on cooking squash, you can check out this guide.
Sauté the Onions and Seasonings
While your squash is cooking, it’s time to infuse some flavor! In a medium skillet, heat 3 tablespoons of light margarine over medium heat. Add your thinly sliced yellow onion along with a teaspoon of red pepper flakes and ¼ teaspoon of garlic powder. Season with salt and freshly ground black pepper to taste. Sauté everything for about 5 to 10 minutes, or until the onions are beautifully browned. This step adds a wonderful depth to your spaghetti squash au gratin.
Combine the Ingredients
Transfer the sautéed onion mixture into your bowl with the spaghetti squash. Now, you’ll stir in ¾ cup of fat-free sour cream and half of your shredded light cheddar cheese. Make sure everything gets well combined, allowing those delightful flavors to mingle. If you're a spicy food lover, feel free to adjust the red pepper flakes to suit your palate, but remember, the kids might appreciate a milder version!
Prepare the Baking Dish
Before baking, preheat your oven to 375 degrees F (190 degrees C). While it's warming up, take a baking dish and coat it with nonstick cooking spray to prevent sticking. Once your dish is ready, transfer the combined mixture from the bowl into the prepared baking dish. Sprinkle the remaining cheddar cheese generously on top to create that glorious gooey crust.
Bake and Broil to Perfection
Finally, it’s baking time! Place your dish in the preheated oven and let it bake for about 20 to 25 minutes. For that irresistible golden top, switch to the broiler for the last 2 to 3 minutes of cooking. This will give you that bubbly, beautifully browned finish that makes Spaghetti Squash Au Gratin truly stand out as a crowd-pleaser.
Enjoy the process as you prepare this delicious recipe, and get ready to impress your family with a nutritious dish that’s hearty enough for even the most devoted meat-and-potatoes fan!

Try Different Cheeses or Spices

Cooking Tips and Notes for Spaghetti Squash Au Gratin
How to Choose the Perfect Spaghetti Squash
Selecting the best spaghetti squash is essential for that delightful au gratin experience. Look for a squash that feels heavy for its size and has a firm, golden-yellow skin free of blemishes. The ideal squash should have a smooth surface and should not yield when you press on it. If you're unsure, consult resources like The Spruce Eats for handy tips on picking seasonal produce.
Tips for Managing Spice Levels for Kids
When it comes to serving spaghetti squash au gratin to little ones, adjusting the spice levels is key. Consider using only a pinch of red pepper flakes, or even omitting them entirely.

Kids may also appreciate a sprinkle of extra cheese on top for that familiar, comforting taste.
