Common Mistakes to Avoid

To make the best Healthy Spaghetti Squash Au Gratin, avoid these common mistakes.

• Skipping the roasting: Not roasting the spaghetti squash properly can lead to a watery dish. Ensure you roast it until tender for the best texture.
• Overcooking the onions: Sautéing onions for too long can cause them to burn and taste bitter. Cook them just until softened for a sweeter flavor.
• Using low-quality cheese: Substituting sharp cheddar with a mild cheese can result in a bland dish. Always opt for high-quality sharp cheddar to enhance the flavor profile.
• Under-seasoning: Failing to season adequately can leave your dish flat. Use salt, pepper, and optional spices like paprika or thyme to elevate the taste.
• Not letting it cool: Serving immediately after baking can make it hard to serve. Letting it cool slightly helps set the dish and makes serving easier.
