Common Mistakes to Avoid

- Incorrect vegetable prep – Not peeling and cubing the butternut squash properly can result in uneven cooking. Make sure to peel, seed, and cut it into uniform pieces for even roasting.
- Overcooking chicken – Cooking the chicken too long before baking can lead to dryness. Cook just until no longer pink and let it finish cooking in the oven for better moisture retention.
- Skipping seasoning – Failing to season with salt, pepper, or herbs can make your dish bland. Always season each layer during cooking to enhance flavors.
- Not using enough cream – A dry bake is less enjoyable. Ensure you add enough cream to create that rich and creamy texture that makes this dish comforting.
