🍯 Why This Recipe Works
- Simple ingredients. Using some basic ingredients, this recipe is pretty frugal and easy to throw together. Great for tight budgets and low maintenance dinner ideas.
- Easy to make. Boil the noodles and saute some stuff in a pot before mixing everything together. This recipe comes together pretty quickly and easily. It's about as easy as our Mac and Cheese Tuna Casserole.
- Stove top or baked. If desired, after mixing everything together in a pot, you can simply serve and enjoy. You don't have to bake it. We prefer it baked, because of the Ritz topping, but it tastes great when served immediately too (and there are fewer dishes to clean later).
🥘 Ingredients
Ingredient Notes:
Egg noodles- Use egg noodles as the base of this recipe. Cook them according to package directions so that they are al dente.
Frozen peas- Adding in frozen peas works best because they'll be warmed through without becoming mushy.
Cream of mushroom- Use a can of cream of mushroom soup to give the casserole a creamy consistency.
Canned tuna- I recommend using canned tuna in water that has been drained and fluffed with a fork.
Cheddar cheese- I like to use sharp or medium cheddar cheese. I recommend the cheese that you shred yourself as it will melt more evenly.
Ritz crackers- For a delicious buttery topping, adding crushed Ritz crackers is a great idea!

🍴 Recipe Tips
- Using Peas- While canned peas can be used in this tuna noodle casserole, opting for frozen peas offers a more vibrant color and a burst of freshness after baking.
- Choosing a Topping- Initially, this casserole was made without any topping. Experimenting with Panko breadcrumbs yielded bland results. Drawing inspiration from my chicken divan casserole, topping with crushed Ritz crackers proved to be the perfect finishing touch.
- Creaminess Variation- For a creamier texture, incorporating 1-2 cups of sour cream is delightful. To cater to picky eaters, combining 1 cup of sour cream with 1 cup of milk achieves creaminess without overwhelming tanginess.

You can use cream of celery along with the remains ingredients and it goes off the charts !
