What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most are pantry staples, with a few fresh items to brighten things up.

• For the casserole:
• 8 ounces (225 g) egg noodles (I recommend Barilla for best texture)
• 2 cans (5 ounces / 140 g each) tuna in water, drained
• 1 cup (240 ml) frozen peas (optional, but adds a nice pop of color and sweetness)
• 1/3 cup (80 g) finely chopped onion
• 2 cloves garlic, minced
• For the creamy sauce:
• 3 tablespoons (45 g) unsalted butter
• 3 tablespoons (24 g) all-purpose flour
• 2 cups (480 ml) milk (whole milk recommended for creaminess; you can use 2% or dairy-free milk if needed)
• 1/2 cup (120 ml) chicken or vegetable broth
• 1 teaspoon Dijon mustard (adds a subtle tang and depth)
• 1 cup (120 g) shredded sharp cheddar cheese
• Salt and freshly ground black pepper, to taste
• For the crispy topping:
• 1 cup (100 g) panko breadcrumbs
• 2 tablespoons (28 g) unsalted butter, melted
• 1/4 cup (25 g) grated Parmesan cheese

Ingredient tips: Use good-quality tuna to avoid any fishy aftertaste. I like Wild Planet brand for its clean flavor. If you want to swap peas for green beans or corn, that works too. For a gluten-free option, substitute the flour with a gluten-free blend and use gluten-free breadcrumbs.

Equipment Needed

• Large pot for boiling noodles (a 4-6 quart / 4-6 liter pot works well)
• Medium saucepan for the creamy sauce
• Mixing bowl for combining the casserole ingredients
• Baking dish (an 8×8 inch / 20×20 cm square or similar size works perfectly)
• Wooden spoon or silicone spatula for stirring
• Measuring cups and spoons
• Colander for draining noodles

If you don’t have a baking dish exactly that size, any oven-safe casserole dish will do. I once used a cast-iron skillet for a rustic twist, and it turned out fantastic. For melting butter and making the sauce, a heavy-bottomed saucepan helps prevent burning. Parchment paper can be handy for easier cleanup but isn’t necessary.

Preparation Method

1. Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or non-stick spray. This step is key so the casserole doesn’t stick—trust me, I learned that the hard way once!
2. Cook the egg noodles: Bring a large pot of salted water to a boil. Add the egg noodles and cook according to package instructions until just al dente (usually about 7-8 minutes). Drain well and set aside. (Pro tip: don’t overcook the noodles—they’ll continue cooking in the oven.)
3. Prepare the creamy sauce: In a medium saucepan, melt 3 tablespoons of butter over medium heat. Once melted, whisk in the flour and cook for about 1-2 minutes, stirring constantly, until it forms a smooth paste and starts to bubble but doesn’t brown.
4. Slowly whisk in the milk and broth: Add them gradually, whisking constantly to avoid lumps. Bring the mixture to a gentle simmer—it should thicken in about 5 minutes. It should coat the back of a spoon but still be pourable. If it gets too thick, add a splash more milk.
5. Add the Dijon mustard and shredded cheddar cheese: Stir until the cheese is fully melted and the sauce is smooth. Season generously with salt and pepper. I usually taste right here—sometimes a pinch of extra salt or a dash of pepper makes all the difference.
6. Combine the casserole ingredients: In a large bowl, mix the cooked noodles, drained tuna, peas, chopped onion, minced garlic, and creamy cheese sauce. Stir gently to combine, making sure everything is coated evenly.
7. Transfer the mixture to the prepared baking dish: Spread it out evenly to ensure consistent baking.
8. Make the crispy topping: In a small bowl, toss the panko breadcrumbs with melted butter and grated Parmesan. Sprinkle this mixture evenly over the casserole. This step gives that beautiful golden crunch that makes this dish unforgettable.
9. Bake: Place the casserole in the oven and bake for 20-25 minutes or until the topping is golden brown and bubbling around the edges. The kitchen will smell incredible at this point—don’t forget to keep an eye so it doesn’t burn.
10. Let it rest for 5 minutes before serving: This helps the casserole set and makes it easier to serve. I know it’s tempting to dig in right away, but patience pays off!

Cooking Tips & Techniques

One trick I’ve learned over the years is to never skip the step of cooking the roux (butter + flour) for a couple of minutes before adding milk. It takes away that raw flour taste and makes your sauce silky smooth. Also, stirring constantly while adding the milk is non-negotiable—lumps are the enemy here.

When mixing the casserole, be gentle! Tuna flakes easily, so rough stirring can turn it into mush. Using a folding motion keeps chunks intact and makes the dish look more appealing.

Breadcrumb topping can burn quickly if your oven runs hot or if it’s too close to the heating element. If you notice the topping browning too fast, tent the casserole loosely with foil halfway through baking.

Lastly, multitasking is a lifesaver—while the noodles cook, prepare your sauce and topping. It shaves off precious minutes and keeps everything warm and fresh.

Variations & Adaptations

• Gluten-Free: Swap regular flour for a gluten-free blend and use gluten-free pasta and breadcrumbs.
• Vegetarian: Replace tuna with cooked chickpeas or shredded jackfruit for a plant-based twist.
• Seasonal Veggies: Swap peas for diced asparagus in spring or roasted butternut squash chunks in fall.
• Spicy Kick: Add a pinch of cayenne pepper or a dash of hot sauce into the creamy sauce for some heat.
• Extra Creamy: Stir in a dollop of sour cream or cream cheese before baking for a richer texture.

I once tried adding caramelized onions and mushrooms for an earthy twist—totally worth the extra effort!

Serving & Storage Suggestions

Serve this casserole hot out of the oven, ideally with a crisp green salad or steamed veggies to balance the richness. A cold glass of white wine or iced tea pairs nicely if you’re in the mood for a drink.

Leftovers keep well—store them in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave, adding a splash of milk if it seems dry. You can also freeze portions for up to 2 months; thaw overnight in the fridge before reheating.

Fun fact: the flavors actually deepen if you let the casserole rest overnight. If you’re a meal prepper, this recipe is a keeper!
