  • 1 cup chicken broth or vegetable broth
  • 1 tsp Dijon mustard
  • 1/2 tsp onion powder

  • 1/4 tsp black pepper
  • 1/2 tsp salt or to taste
  • 2 cups shredded sharp cheddar cheese
For the Casserole Mix-ins
  • 2 5 oz cans tuna in water drained very well
  • 1 cup frozen peas thawed
  • 1 cup celery finely chopped
For the Crunchy Topping
  • 1 cup panko breadcrumbs
  • 2 tbsp unsalted butter melted

Equipment

  • Large Pot
  • Large Skillet or Saucepan
  • 9×13 inch baking dish
  • Whisk
  • Mixing Spoons

Method
 

Prepare the Base
  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. Cook the wide egg noodles according to package directions in a large pot of salted boiling water until al dente. Drain thoroughly and set aside.
Make the Creamy Sauce
  1. In a large skillet or saucepan, melt 3 tablespoons of unsalted butter over medium heat. Whisk in the 1/4 cup all-purpose flour and cook for 1-2 minutes, stirring constantly, to create a roux.
  2. Gradually whisk in the 2 cups whole milk and 1 cup chicken broth until the mixture is smooth. Bring to a gentle simmer, stirring constantly, until the sauce thickens (this usually takes about 3-5 minutes). Remove the skillet from the heat.
  3. Stir in the 1 teaspoon Dijon mustard, 1/2 teaspoon onion powder, 1/4 teaspoon garlic powder, 1/4 teaspoon black pepper, and 1/2 teaspoon salt. Add the 2 cups shredded sharp cheddar cheese, stirring until it is completely melted and the sauce is smooth and creamy.
Assemble the Casserole
  1. To the cheese sauce, add the well-drained tuna, thawed frozen peas, and finely chopped celery. Gently add the cooked egg noodles. Stir everything together until all ingredients are evenly coated in the creamy sauce.
  2. Pour the tuna casserole mixture into the prepared 9×13 inch baking dish, spreading it evenly.
Prepare and Bake Topping
  1. In a small bowl, combine the 1 cup panko breadcrumbs with the 2 tablespoons melted unsalted butter. Sprinkle this mixture evenly over the top of the casserole.
  2. Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly around the edges and the panko topping is golden brown and crisp.
Serve
  1. Remove from the oven and let the casserole stand for 5 minutes before serving. This allows the sauce to set slightly.

Notes

For an extra layer of flavor, you can sauté a finely diced small onion with the celery before adding them to the sauce. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.

Pro Tips for Making This tuna casserole

When it comes to creating the perfect tuna casserole, a few little tricks I’ve learned over the years can make all the difference, transforming a good dish into a truly unforgettable one.

My Secret Trick: I always undercook the wide egg noodles by about a minute or two from the package directions. They’ll finish cooking in the oven, absorbing all that glorious creamy sauce without becoming mushy. It gives the casserole that perfect tender-chewy bite!

For an extra layer of flavor in your creamy sauce, don’t shy away from a good quality chicken broth. It adds a depth that water simply can’t achieve. I also love to whisk in the Dijon mustard at the end for a subtle tang that brightens the whole dish without being overpowering.

Ensure your cheese is freshly shredded. Pre-shredded cheeses often contain anti-caking agents that can prevent them from melting as smoothly. A block of sharp cheddar, grated at home, will give you that wonderfully gooey, rich texture in your tuna casserole.

Don’t skip toasting your panko breadcrumbs with butter before topping the casserole. This extra step guarantees a gorgeously golden-brown, irresistibly crunchy topping that stays crisp, providing that essential textural contrast we all love in a classic tuna casserole.

Fun Variations for tuna casserole

The beauty of a classic tuna casserole is how wonderfully it lends itself to creative twists! It’s like a blank canvas just waiting for your personal touch. Here are a few ideas I’ve experimented with to keep things exciting:

Spice It Up

My friend Sarah always asks me to add a pinch of smoked paprika or a dash of cayenne pepper to the creamy sauce. It gives the tuna casserole a subtle warmth and a lovely depth of flavor that’s truly addictive without being overly spicy.

Veggie Boost

If you want to sneak in more greens, consider adding a cup of finely chopped fresh spinach or blanched broccoli florets along with the peas and celery. Just make sure to squeeze out any excess water from the spinach so it doesn’t make the casserole watery.

Cheesy Swaps

While sharp cheddar is a classic, you can easily play with other cheeses. A blend of Gruyere and white cheddar offers a more sophisticated flavor profile, or for a sharper kick, try a bit of Parmesan in your tuna casserole.

What to Serve With tuna casserole

This hearty tuna casserole is truly a meal in itself, but a few simple accompaniments can elevate it into a truly memorable dinner. I always think about balancing the richness of the casserole with something fresh and bright.

A simple, crisp green salad with a zesty vinaigrette is my go-to pairing. The fresh crunch and tangy dressing beautifully cut through the creamy richness of the tuna casserole, making each bite feel renewed.

My mom always loved to serve a side of steamed green beans or asparagus, lightly seasoned with a squeeze of lemon. It adds a lovely pop of color and a fresh, healthy element to the meal.

For a comforting carbohydrate companion, especially if you have a big appetite, a slice of crusty bread or garlic toast is perfect for soaking up every last bit of that delicious creamy sauce from your tuna casserole. It’s pure comfort food at its best!

How to Store tuna casserole

Making a batch of delicious tuna casserole means you might have some lovely leftovers to enjoy later, and with a few simple storage tips, it’ll taste just as wonderful!

Fridge Storage

To keep your leftover tuna casserole fresh and flavorful, allow it to cool completely before transferring it to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days. This makes it perfect for a quick lunch or another cozy dinner during the week.

Freezer Tips

If you’re planning to enjoy your tuna casserole further down the line, it freezes wonderfully! Once cooled, divide the casserole into individual portions or a larger freezer-safe container, then cover tightly with plastic wrap and foil. It can be stored in the freezer for up to 2-3 months. I like to label mine with the date, so I always know when it was made!

Reheating Methods

When you’re ready to enjoy, thaw frozen tuna casserole in the refrigerator overnight. To reheat, cover the casserole dish with foil to prevent drying out and warm it in a preheated oven at 300°F (150°C) until heated through, about 20-30 minutes for individual portions or longer for a whole casserole. My personal tip for reheating is to add a splash of milk or broth before warming if it seems a little dry; it helps bring back that creamy texture!

Nutritional Benefits

While we cherish this tuna casserole for its comforting appeal, it also offers some lovely nutritional benefits. Tuna, our star ingredient, is a fantastic source of lean protein and heart-healthy omega-3 fatty acids. Paired with wide egg noodles for energy and dairy for calcium, it’s a treat that’s both satisfying and nourishing, embodying my philosophy of wholesome, homemade goodness.

FAQs

Faq 1

Can I make this tuna casserole ahead of time?
Absolutely! You can assemble the casserole (without the crunchy topping) up to a day in advance. Cover it tightly and refrigerate. Add the panko topping just before baking for the best crispness.

Faq 2

What kind of tuna should I use?
I recommend using tuna packed in water for this tuna casserole. It tends to be lighter in flavor and blends seamlessly into the creamy sauce without adding extra oil. Just be sure to drain it well!

Faq 3

Can I substitute other pasta?
Yes, you can! While wide egg noodles are classic for tuna casserole, feel free to use other short pasta shapes like elbow macaroni, penne, or shells. Just ensure you cook them according to package directions.

Faq 4

How do I prevent the topping from getting soggy?
The key to a crunchy topping on your tuna casserole is using panko breadcrumbs, which are inherently crispier, and toasting them in butter first. Also, add the topping right before baking.

Conclusion

There’s something truly special about a dish that brings smiles and comfort to the table, and this classic tuna casserole does just that. It’s a reminder that with a little love and patience, even the simplest ingredients can come together to create a meal that’s not only delicious but also rich with warmth and cherished memories.
