Chef Emma’s Helpful Tips
- Make Ahead: Assemble the casserole a day in advance and store it in the fridge—just add a few extra minutes to the baking time if baking straight from cold.
- Ingredient Swaps: Use Greek yogurt instead of sour cream for a healthier option, or swap the cream of chicken soup for cream of mushroom if you prefer a vegetarian variant.
- Storage Suggestions: Leftovers can be stored in an airtight container in the fridge for up to three days. This casserole reheats beautifully in the oven or microwave!
- Cutting Tips: Allow the casserole to cool for a few minutes before cutting; this will help it hold together better when serving.
