Recipe Notes
This Tuna Noodle Casserole can be easily adapted to your preferences. Here are some helpful tips:
- Make sure to drain the tuna well to prevent a watery casserole.
- For a crunchier topping, add the crushed chips in the last 10 minutes of baking.
- The casserole can be assembled up to 24 hours in advance and stored in the refrigerator before baking.
- If baking from cold, add 5-10 minutes to the cooking time.
- Leftovers will keep in the refrigerator for up to 3 days.
- For a lighter version, use low-fat milk and reduced-fat cheese.
- Feel free to substitute the peas with other vegetables like corn or mixed vegetables.
For best results, let the casserole rest for 5-10 minutes after baking. This allows the sauce to thicken and makes serving easier. The crushed chip topping might lose its crunch when stored, but the flavors will continue to develop, making this dish just as delicious the next day.
