Pro Tips
To ensure your casserole comes out perfectly every time, follow these pro tips:

- Let the casserole rest: Allowing it to rest for a few minutes before serving helps the layers set, making it easier to cut and serve.
- Don’t overcook: Keep an eye on the casserole in the oven–overbaking can lead to a dry texture. Aim for a slightly jiggly center when you take it out.
- Customize veggies: Feel free to swap in your favorite vegetables or add spinach for extra nutrition without compromising flavor.
- Make-ahead option: Assemble the casserole the night before and store it in the refrigerator until you’re ready to bake it in the morning.
