Notes
- Tuna: Opt for tuna in water for a lighter casserole, or use oil-packed tuna for a richer flavor.
- Customize your veggies: Add frozen peas, corn, chopped carrots, or even mushrooms to sneak in some extra veggies.
- Cheese: While Cheddar is great, try mixing in some mozzarella, Gouda, or Parmesan for a different taste.
- Crunchy topping alternatives: If you’re out of Panko, crushed potato chips or Ritz crackers make a great substitute for a crispy finish.
- Make it gluten-free: Swap regular noodles for gluten-free pasta and use gluten-free flour to cater to dietary needs.
- Cooking the roux: Don’t rush cooking the flour and fat mixture; let it cook for a few minutes to avoid a floury taste.
- Add a splash of color: Fresh parsley not only adds flavor but also makes your dish pop with color.
Storage and Reheating Instructions
- Cool: Let the casserole cool to room temperature before you pack it up.
- Refrigerate: Store leftovers in an airtight container in the refrigerator. They’ll keep well for up to 3 days.

- Reheat: To reheat, sprinkle a little water over the top and cover with aluminum foil. Warm it in the oven at 350°F until heated through.
