History
Tuna Noodle Casserole became popular in the mid-20th century, particularly during the 1940s and 1950s. It was first created as a budget-friendly, easy-to-make dish during the Great Depression and World War II when home cooks were encouraged to stretch their ingredients. The use of pantry staples like canned tuna, egg noodles, and cream of mushroom soup made it a convenient option for busy families. As post-war America embraced convenience foods, this dish solidified its place in American kitchens as a go-to comfort food.
Ingredients
- Cream of chicken soup – You can also use cream of mushroom soup.
- Mayonnaise – Any kind of mayo will work.
- Milk – Any kind of milk.
- Onion – Chopped.
- Celery – Diced.
- Butter
- Garlic powder
- Onion powder
- Peas – Frozen peas.
- Tuna – Use canned tuna. I like albacore packed in water.
- Egg noodles
- Cheese – I like sharp cheddar cheese.
- White bread – With the crusts removed.
How To Make Classic Tuna Noodle Casserole
- Preheat your oven to 350°F (175°C) and spray a 2-quart casserole dish with nonstick cooking spray.
- Cook the egg noodles according to the package instructions, but for 1 minute less so they’re al dente. Drain, rinse under cold water, and set aside.
- Melt 2 tablespoons of butter over medium heat. Add the diced onion and celery, and cook until they are soft and translucent, about 5-7 minutes.
- Stir together the can of cream of mushroom soup, mayonnaise, milk, garlic powder, and onion powder until well combined in a large mixing bowl. Fold in the sautéed onions and celery, peas, drained tuna, and cooked noodles. Mix until everything is evenly coated with the sauce.
- Tear the white bread slices into small pieces and add them to a small bowl with the shredded cheese. Melt the remaining 1 tablespoon of butter and drizzle it over the bread pieces. Toss to coat the bread evenly with the butter, and then sprinkle the bread and cheese pieces over the cheese layer.
- Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is heated through.
- Remove from the oven and let it cool slightly before serving. Enjoy!
Step-By-Step Process
Chef Jenn’s Tips
- If you want to make this ahead of time, assemble the casserole but don’t add the bread topping until you’re ready to bake. This way, it’ll stay crunchy.
- Use canned tuna that’s packed in water rather than oil for a lighter flavor.
- If you love cheese, feel free to add a bit more to the topping to make it extra cheesy.
Make It A Meal
Serve this Classic Tuna Noodle Casserole with a side salad to add some fresh crunch to your meal, or pair it with steamed veggies like broccoli or green beans. For a heartier dinner, you can even serve it alongside some garlic bread to soak up all the delicious sauce.
Storage
Store any leftover casserole in an airtight container in the fridge for up to 3 days. To reheat, pop it in the microwave or warm it up in the oven to keep the topping crispy. If you want to freeze this dish, you can assemble the casserole without baking it, then cover it tightly with foil and freeze for up to 3 months. When you’re ready to bake, let it thaw in the fridge overnight before cooking it according to the instructions.
