Ingredients

  

For the Casserole

• 12 oz Wide Egg Noodles
• 3 tbsp Unsalted Butter
• 1 medium Yellow Onion finely chopped
• 2 ribs Celery finely chopped
• 8 oz Cremini Mushrooms sliced
• 1/4 cup All-Purpose Flour
• 2 cups Whole Milk room temperature
• 1 cup Chicken or Vegetable Broth
• 1 tsp Dijon Mustard
• 1/2 tsp Dried Thyme
• 1 tsp Salt or to taste
• 1/2 tsp Black Pepper freshly ground
• 2 cans (5 oz each) Tuna in water drained and flaked
• 1 cup Frozen Sweet Peas do not thaw
• 1 cup Shredded Sharp Cheddar Cheese

For the Crumb Topping

• 3/4 cup Panko Breadcrumbs
• 2 tbsp Unsalted Butter melted
• 1/4 cup Grated Parmesan Cheese
• 2 tbsp Fresh Parsley chopped

Equipment

• 9×13 inch Casserole Dish
• Large pot
• Large Skillet
• Mixing Bowl

Method

 

Prepare Noodles and Oven

• Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish.
• Cook the egg noodles in a large pot of salted boiling water according to package directions, but cook for 2 minutes less than the recommended time to achieve al dente. Drain well and set aside.

Make the Creamy Sauce

• While the noodles are cooking, melt 3 tablespoons of butter in a large skillet or Dutch oven over medium heat. Add the chopped onion and celery and sauté for 4-5 minutes until softened.
• Add the sliced mushrooms to the skillet and cook for another 5-7 minutes, until they have released their moisture and started to brown. Sprinkle the all-purpose flour over the vegetables and stir constantly for 1 minute to cook out the raw flour taste.
• Slowly whisk in the room temperature milk and the broth until the mixture is smooth. Bring to a simmer, stirring frequently, until the sauce thickens, about 3-5 minutes. Remove from heat and stir in the Dijon mustard, dried thyme, salt, and pepper.

Assemble the Casserole

• To the skillet with the sauce, gently fold in the cooked egg noodles, the drained and flaked tuna, the frozen peas, and the shredded cheddar cheese. Stir until everything is evenly coated in the creamy sauce.
• Pour the mixture into the prepared casserole dish and spread it into an even layer.
• In a small mixing bowl, combine the panko breadcrumbs, 2 tablespoons of melted butter, grated Parmesan cheese, and chopped fresh parsley. Mix until the breadcrumbs are evenly moistened. Sprinkle the crumb topping evenly over the casserole.

Bake and Serve

• Bake uncovered for 20-25 minutes, or until the casserole is hot and bubbly and the topping is golden brown and crisp.
• Remove from the oven and let the casserole rest for 5-10 minutes before serving. This allows it to set up slightly.

Notes

For an extra rich sauce, you can substitute half of the milk with half-and-half. Feel free to add other vegetables like carrots or green beans. Sauté them with the onions and celery. Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.

Pro Tips for Making This tuna noodle casserole

Getting that perfect, comforting result every time is easy with a few little tricks I’ve learned over the years. These tips will help you make the best tuna noodle casserole your family has ever had.

For the Creamiest Sauce

The secret to a sauce that’s rich but not heavy is how you build it. After sautéing your onions, celery, and mushrooms, sprinkle the flour over them and cook it for at least a minute. This step toasts the flour and gets rid of any raw taste. Then, when you add the milk and broth, pour it in slowly while whisking constantly. This is the key to preventing lumps and creating a silky-smooth base for your creamy casserole recipe.

Don’t Overcook the Noodles

This is a big one! Remember that the noodles will continue to cook in the oven as the casserole bakes. I always recommend boiling your egg noodles for about 2 minutes less than the package directions suggest. They should be very al dente—still firm with a good bite. This ensures they’ll soak up that delicious sauce without turning mushy, giving your finished tuna noodle casserole the perfect texture.

Let It Rest Before Serving

I know how tempting it is to dig in the second it comes out of the oven, but letting the casserole rest for 5-10 minutes is a game-changer. This brief resting period allows the sauce to set up and thicken slightly, so it’s perfectly creamy and clings to the noodles instead of being runny. It makes for easier serving and a better bite every single time.

My Secret Trick: My favorite way to elevate the flavor of the sauce is with a teaspoon of Dijon mustard. You won’t taste the mustard itself, but it adds a tiny, bright tang that cuts through the richness and makes all the other savory flavors—the cheese, the mushrooms, the tuna—pop. It’s a simple addition that makes a huge difference in this classic homestyle family dinner.

Fun Variations for tuna noodle casserole

One of the reasons I love this tuna noodle casserole is how wonderfully adaptable it is. It’s a fantastic canvas for using what you have on hand or for catering to your family’s tastes. Here are a few of our favorite ways to mix things up and make it a new easy weeknight meal every time.

Change Up the Protein

While tuna is classic, this creamy casserole recipe works beautifully with other proteins. Canned salmon is a fantastic substitute and offers a slightly richer flavor. You can also use about two cups of shredded rotisserie chicken for a heartier, chicken-and-noodles feel. If you have leftover holiday turkey, that works wonderfully, too!

Add More Veggies

This is a great recipe for cleaning out the veggie drawer. Feel free to add a cup of steamed broccoli florets, corn kernels (frozen is fine!), or sautéed sliced carrots. For a bit of color and a mild, sweet flavor, you could even stir in some chopped roasted red peppers. Just be sure to pre-cook any hard vegetables so they are tender in the final dish. If you love creative casseroles, you should try our Big Mac Casserole for a fun twist on a family favorite.

Swap the Cheese or Topping

Sharp cheddar gives this tuna noodle casserole a classic, tangy flavor, but don’t be afraid to experiment! A mix of Gruyère and white cheddar would add a nutty, complex flavor. For a milder, extra-gooey casserole, try Colby or Monterey Jack. You can also change the topping by swapping the Panko breadcrumbs for crushed potato chips or buttery cracker crumbs for an extra-salty crunch.

What to Serve With tuna noodle casserole

This tuna noodle casserole is a hearty, all-in-one meal, but a simple side dish can round it out perfectly and turn it into a complete homestyle family dinner. I like to stick with sides that are fresh, simple, and add a nice contrast in texture and flavor.

• A Simple Green Salad: A crisp salad with leafy greens, cucumber, and cherry tomatoes tossed in a bright lemon vinaigrette is my go-to. The acidity and freshness cut through the richness of the creamy casserole recipe, making the whole meal feel balanced.
• Steamed or Roasted Vegetables: A side of steamed green beans, tender-crisp asparagus, or roasted broccoli adds a welcome touch of color and nutrition. I usually just toss them with a little olive oil, salt, and pepper. It’s simple, and it lets the flavors of the tuna noodle casserole shine.
• Crusty Bread or Garlic Bread: There’s nothing better than a warm slice of crusty bread for sopping up every last bit of that delicious, creamy sauce. Garlic bread is also a fantastic choice that my family always gets excited about.
• A Vegetable Casserole: For a truly comforting feast, you could pair it with another baked dish. Our Yellow Squash Casserole is a wonderful, savory option that complements this dish beautifully.

How to Store tuna noodle casserole

One of the best things about casseroles is that they make fantastic leftovers! This dish stores and reheats beautifully, making it perfect for weeknight lunches or for a night when you don’t feel like cooking.

In the Refrigerator

To store leftovers, allow the tuna noodle casserole to cool completely, then cover the dish tightly with foil or transfer it to an airtight container. It will keep well in the refrigerator for up to 4 days. Reheating is a breeze—just pop it in a 350°F (175°C) oven until it’s hot and bubbly, usually about 20-25 minutes.

In the Freezer

This is a great make-ahead meal. You can freeze the entire unbaked or baked casserole. For an unbaked casserole, assemble it completely but leave off the Panko topping. Cover it tightly with a layer of plastic wrap and then a layer of foil. To bake from frozen, add about 20-25 minutes to the baking time and add the topping during the last 20 minutes of cooking. A baked tuna noodle casserole can also be frozen for up to 3 months. Just like this dish, our Hobo Casserole is another freezer-friendly meal that’s perfect for planning ahead.

Nutritional Benefits

While pure comfort is the main goal here, it’s nice to know that this dish brings some nourishment to the table, too. This tuna noodle casserole is packed with protein from the tuna and milk, which helps keep everyone feeling full and satisfied. It’s a wholesome, balanced meal that makes feeding your family something hearty and comforting feel good.

FAQs

Can I make this tuna noodle casserole ahead of time?

Absolutely! This is a perfect make-ahead dish. You can assemble the entire casserole without the Panko topping, cover it tightly, and refrigerate it for up to 2 days. When you’re ready to eat, just sprinkle the topping on and bake as directed, adding about 10-15 minutes to the cooking time since it will be chilled.

Can I use something other than canned tuna?

Yes, this casserole is very versatile. Canned salmon is a great alternative with a slightly richer flavor. You can also use about 2-3 cups of shredded cooked chicken or turkey. It’s a wonderful way to use up leftovers from a roasted chicken, transforming it into a completely new and delicious meal.

Why is my casserole dry?

A dry tuna noodle casserole is usually caused by one of two things. First, the noodles might have been overcooked initially, causing them to absorb too much of the sauce. Be sure to cook them just until al dente. Second, there might not have been enough sauce to begin with. This recipe has a generous amount of creamy sauce to ensure every bite is moist and delicious!

Can I use canned cream of mushroom soup instead of making the sauce?

You certainly can as a shortcut, but I truly believe the homemade sauce is what makes this the best tuna noodle casserole. The from-scratch sauce is made with simple pantry staples like butter, flour, milk, and broth, and it has a much fresher, richer flavor without any preservatives. It only takes a few extra minutes and it elevates the entire dish.

Conclusion

There is so much love baked into this tuna noodle casserole. It’s more than just a meal; it’s a feeling of warmth, comfort, and connection that brings everyone to the table. It’s proof that simple ingredients and a little bit of time can create something truly special and delicious, making it the perfect easy weeknight meal. I hope this recipe brings as much joy to your family as it does to mine. For another one of our family’s favorite one-pot meals, be sure to check out my hearty Sausage Potato Casserole.
