There’s something about a warm, bubbling casserole that feels like a big hug on a chilly day. The Best Classic Tuna Noodle Casserole is one of those dishes that transports you back to simpler times, when mom or grandma would serve it fresh from the oven. It’s pure comfort food that makes family dinners feel special and cozy, perfect for gathering around the table.
This casserole features a delightful mix of ingredients, including 2 cups egg noodles, 1 can (15 oz) tuna, 1 can (10.5 oz) cream of mushroom soup, and 1 cup frozen peas. The addition of 1/2 cup milk creates a creamy texture, while 1 cup shredded cheddar cheese adds that savory richness we all love. With a dash of garlic powder, salt, and pepper, the flavor profile is both simple and satisfying. For an optional crunchy topping, you can sprinkle 1/2 cup bread crumbs on top, making every bite delightfully textured.
Preparing this dish is a breeze. Begin by preheating your oven to 350°F (175°C). While the oven warms up, you can cook the egg noodles until tender and then drain them. Combine the noodles with the tuna, soup, peas, milk, garlic powder, salt, pepper, and half of the cheese in a large bowl. After mixing it all together, transfer it to a greased baking dish, sprinkle on the remaining cheese and breadcrumbs, and slide it into the oven. After about 25-30 minutes, your casserole will be hot and bubbly, ready to serve.
This casserole is perfect for chilly nights, when you want a meal that comforts as much as it fills. It also makes for a great dish to bring to potlucks or family gatherings, where everyone can enjoy its homestyle goodness.

Tuna Tips
When it comes to choosing the right tuna for this casserole, consider using solid white albacore tuna. It tends to have a firmer texture and milder flavor compared to chunk light tuna, providing a nice bite in every spoonful. Always look for tuna packed in water for a more delicate taste and better nutrition. Be sure to drain it well before combining it with the other ingredients to prevent a watery casserole.
Options for Substitutions
- Use pasta shapes like shells or rotini instead of egg noodles for added flair.
- Substitute canned salmon or even shredded chicken if you don’t have tuna on hand.
- Swap cream of mushroom soup with cream of chicken soup for a different flavor.
- Consider using frozen corn instead of peas for a sweeter touch.
- For a lighter version, use low-fat milk and reduced-fat cheese.
- Replace regular breadcrumbs with panko crumbs for an extra crispy topping.
Watch Out for These Mistakes
Even with a simple recipe like this, there are a few common pitfalls to avoid.
First, don’t forget to drain your tuna properly. Excess moisture can lead to a soggy casserole, which no one wants. Second, be careful not to overcook your egg noodles. They should be al dente because they will continue cooking in the oven.
Next, it’s essential to season to your taste. A little salt and pepper go a long way, so be sure to taste as you mix. Lastly, wait until right before baking to add the cheese and breadcrumbs. This will keep them from becoming overly brown or burnt during baking.

What to Serve With Best Classic Tuna Noodle Casserole?
Pair your tuna noodle casserole with a few simple sides for a complete meal. A crisp green salad with a light vinaigrette can balance the richness of the casserole. You might also serve warm garlic bread to soak up any leftover creamy sauce. Steamed vegetables, such as broccoli or green beans, make for a nutritious addition to your plate.
Storage Instructions
Store: Leftovers can be refrigerated in an airtight container for up to 3 days.
Freeze: You can freeze this casserole for up to 3 months. Just be sure to wrap it tightly in plastic wrap and then foil.
Reheat: For gentle reheating, warm in the oven at 350°F (175°C) until heated through, about 15-20 minutes. In the microwave, heat in short intervals until hot, stirring in between.
