Tips & Variations

- Try topping the casserole with crispy bacon bits for extra texture and flavor.
- Use smoked Cheddar for a deeper, smoky taste that complements the rutabagas nicely.
Storage

FAQs
Can I use yellow turnips instead of rutabagas?
Yes, yellow turnips can be substituted but may result in a slightly sharper flavor. Adjust seasoning as needed to balance the taste.
Is it necessary to refrigerate the casserole before baking?
Refrigerating helps the flavors meld and can improve the texture, but you can bake it immediately if short on time. Just allow for a slightly longer baking time.
