Cheesy Spaghetti Squash Gratin

Place the spaghetti squash in a covered container and add about 1/8 of an inch of moisture. Microwave for the duration of 10 to 12 minutes, or until it reaches your desired level of tenderness. Remove the squash from the microwave and use a utensil to scrape out its interior contents.

While the squash is cooking, melt margarine in a medium-sized pan over a moderate heat setting. At this time, cook the onion along with some red pepper flakes, garlic powder, salt, and pepper until the onion has reached a browned state. This process should take anywhere from 5 to 10 minutes.

Preheat your oven to a temperature of 375 degrees Fahrenheit (or 190 degrees Celsius). Grease a baking dish with nonstick cooking spray beforehand.

Combine the cooked spaghetti squash, onion mixture, sour cream, and half of the Cheddar cheese in a bowl. Transfer this mixture to the prepared baking dish and top it off with the remaining Cheddar cheese.

Bake the combined mixture in the preheated oven for 20 to 25 minutes. During the last 2 to 3 minutes of baking, turn on your broiler and cook until the top is golden brown.
