This Homemade Tuna Noodle Casserole is an update on an old classic. It's made using a flavorful homemade sauce that elevates it taking this potluck star to another level.
Homemade Tuna Noodle Casserole
Tuna Noodle Casserole isn't a new dish, it's a beloved vintage casserole we've eaten for generations. The most common version utilizes canned soups for the sauce making it a super easy dish to prepare. While I use canned soups from time to time in casserole recipes such as crockpot chicken and dressing and au gratin ranch potatoes, this tuna casserole is made with a homemade sauce to kick it up a few notches.
Tips for Making Homemade Tuna Noodle Casserole
- I use wide, not extra wide noodles, in this dish.
- You can use white cheddar, regular cheddar, Gruyere or Swiss cheese in this dish. In a pinch, monterey jack makes a delicious mild cheese sauce. Adapt the cheese using your preference or, what you have on hand.
- I recommend topping this with crushed french fried onions however, you can also use buttered bread crumbs or even crushed potato chips.
- Depending on your family's taste one cup of peas may be ample. If they love peas, you may use up to two cups.
- Adding seafood seasoning gives this dish a little something extra in flavor. I use Old Bay and Seafood Magic but, there are a plethora of seafood seasoning combinations available.
What to Serve with Tuna Casserole
This casserole can stand alone, if you're in a hurry. That being said, a wedge salad and some warm garlic bread goes a long way alongside this filling pasta dish. You may also enjoy this tuna salad recipe from Spend with Pennies.
