Common Mistakes to Avoid

When making the Chicken Alfredo Spaghetti Squash Casserole, there are a few common errors that can affect your dish. Here are some mistakes to watch out for:

• Overcooking the chicken: If you cook the chicken too long, it can become dry. Use a meat thermometer to ensure it reaches 165°F.

• Not seasoning adequately: A lack of seasoning can make your casserole bland. Make sure to season both the chicken and vegetables well before baking.

• Ignoring spaghetti squash cooking time: Undercooking or overcooking the spaghetti squash can affect texture. Aim for fork-tender strands but don’t let it get mushy.

• Using non-Whole30 compliant sauces: Always check labels if using store-bought sauces like Alfredo. Stick to Whole30-approved brands or make your own.

• Skipping the preheating step: Not preheating the oven can lead to uneven cooking. Always preheat to ensure consistent results.
