How to Make Classic Tuna Noodle Casserole Recipe
Step 1: Prepare the Noodles
Start by preheating your oven to 350 degrees Fahrenheit and set the rack in the middle to ensure even cooking. Boil the egg noodles just until they are al dente—meaning they’re slightly firm and not fully cooked through—as they will finish cooking in the oven. Once done, drain the noodles and set them aside to wait for the creamy mixture.
Step 2: Mix the Creamy Sauce
In a large bowl, combine the cream of mushroom soup, sour cream, mayonnaise, salt, pepper, shredded cheddar cheese, and milk. Stir these together until fully integrated, forming a luscious, cheesy base that’s bursting with classic flavors.
Step 3: Fold in Tuna, Noodles, and Peas
Gently fold in the drained tuna first; be careful to keep the tuna in nice chunks without mashing it. Next, add the cooked egg noodles and peas, stirring just until everything is evenly coated with that creamy mixture. This step is where the dish truly comes together in harmony.
Step 4: Assemble and Bake
Spray a casserole dish with cooking spray to prevent sticking, then pour in the tuna and noodle mixture, spreading it evenly. Sprinkle the crushed ruffles chips and French fried onions generously over the top—they are this casserole’s signature crunchy crown. Bake in the preheated oven for 20 to 30 minutes, or until the topping turns a golden brown and the casserole is bubbling with warmth underneath.
How to Serve Classic Tuna Noodle Casserole Recipe

Garnishes
To add a fresh twist, garnish with chopped fresh parsley or a sprinkle of chopped chives. These green herbs add a lovely pop of color and a subtle freshness that balances the rich casserole beautifully.
Side Dishes
This casserole pairs wonderfully with light and crisp sides. A fresh green salad with a lemon vinaigrette or steamed broccoli can brighten the meal and add a nutritious contrast to the creamy main dish.
Creative Ways to Present
For a fun family dinner or a casual potluck, serve the casserole in individual ramekins topped with a dollop of sour cream and extra fried onions. Alternatively, try layering the ingredients in a clear glass bakeware to show off the colorful layers of noodles, tuna, peas, and golden topping—always a crowd-pleaser.
Make Ahead and Storage
Storing Leftovers
Leftover Classic Tuna Noodle Casserole Recipe can be stored in an airtight container in the refrigerator for up to 3 days. This makes it perfect for quick lunches or reheated dinners during a busy week.
Freezing
You can freeze the casserole either before or after baking. If freezing before baking, assemble the casserole as usual, cover tightly with foil, and freeze for up to 2 months. When ready to eat, bake from frozen, adding extra time as needed until bubbly and heated through.
Reheating
To reheat, cover the portion with foil and warm in a 350-degree oven for about 15-20 minutes or until heated thoroughly. Alternatively, microwave individual servings for a quicker option, stirring halfway through to ensure even heating.
FAQs
Can I use canned peas instead of frozen?
Yes, canned peas work as well. Just drain them well and add them at the same stage you would add frozen peas. They’ll add a softer texture but still bring that mild sweetness to the dish.
Is it okay to substitute cream of mushroom soup with cream of celery?
Absolutely! Cream of celery soup offers a slightly different flavor profile but still provides that creamy texture essential for the Classic Tuna Noodle Casserole Recipe. Feel free to experiment and find your favorite twist.
Can I make this recipe gluten-free?
Yes, substitute the egg noodles with your favorite gluten-free pasta. Also, make sure to use gluten-free cream soups and crunchy toppings like gluten-free chips and fried onions to keep things safe for those with gluten sensitivities.
Why should I cook the noodles al dente?
Cooking the noodles al dente ensures they won’t become mushy after baking. Since they continue to cook in the oven, starting with noodles that are just slightly undercooked keeps everything perfectly tender and pleasing to the bite.
Can I add other veggies to this casserole?
Definitely! Feel free to stir in diced carrots, mushrooms, or even chopped spinach before baking. Adding more veggies can boost the nutrition and make the dish even heartier while keeping that classic vibe.
