Best ways to enjoy it
This casserole is fantastic on its own but can be complemented in various ways. Here are a few serving suggestions:
- Serve it hot with a fresh side salad for a balanced meal.
- Pair it with garlic bread to soak up all that cheesy goodness.
- A dollop of homemade ranch or spicy aioli on the side can elevate the flavor profile even more.

How to store
Keeping leftovers fresh
If you happen to have leftovers, storing them properly is key to keeping the dish flavorful for future meals. Here’s how to do it:
- Store the casserole in an airtight container in the refrigerator for up to 3-4 days.
