Common Mistakes to Avoid

When making Chicken Alfredo Spaghetti Squash Casserole, it’s easy to overlook some key steps. Here are some common mistakes and how to avoid them:

• Skipping the seasoning: Many people forget to season the chicken and vegetables adequately. Always sprinkle salt and pepper generously to enhance the flavors.

• Not cooking spaghetti squash properly: If you don’t bake the spaghetti squash long enough, it won’t have the right texture. Ensure it’s tender before scraping out the strands.

• Using too much or too little sauce: Finding the balance with the Alfredo sauce is crucial. Use just enough to coat without drowning the casserole; this prevents sogginess.

• Overcrowding the casserole dish: Filling your dish too much can lead to uneven cooking. Make sure there’s space for heat to circulate for even baking.

• Neglecting to check cooking times: Every oven is different. Keep an eye on your casserole during baking and adjust time as needed for optimal results.
