Ingredients Breakdown

A classic casserole brings together creamy, savory, and slightly tangy flavors. Choosing good-quality components will elevate your dish. Here’s what you’ll need and why:

Ingredient	Purpose
Wide Egg Noodles	Provide a tender, hearty base
Unsalted Butter	Adds richness and helps create the roux
Garlic & Shallots	Give the foundation aromatic, subtle sweetness
All-Purpose Flour	Thickens the sauce into a cream
Half and Half	Offers creamy texture without excess heaviness
Dijon Mustard	Lends brightness, balancing rich dairy
Sharp Cheddar Cheese (white or yellow)	Delivers sharp, melty flavor
Solid White Albacore Tuna (in water)	Maintains texture, stands up to baking
Frozen Peas	Infuse color and a mild sweetness
Kosher Salt & Black Pepper	Enhance flavors throughout
Panko Breadcrumbs	Responsible for the signature crispy topping
Parmesan Cheese	Adds savory, nutty flavor to the crust
Lemon Zest	Brightens the whole dish, cuts heaviness
Olive Oil	Helps the crumb topping achieve a golden color
Fresh Chives (optional)	For garnish and a pop of color

Ingredient Notes:
– Substitute Greek yogurt or sour cream for half and half if you like extra tang.
– Macaroni, fusilli, or shells can replace egg noodles—just cook to al dente to avoid mushiness.
– For a gluten-free option, swap in a gluten-free pasta and use a 1:1 gluten-free flour blend in the sauce.

Step-by-Step Cooking Instructions

Making tuna noodle casserole is straightforward. Here’s how to transform basic ingredients into a satisfying bake:

1. Prep Your Cooking Tools

Grease a 9×13-inch baking dish with oil or butter. Preheat your oven to 400°F (200°C). This ensures even cooking and crisp edges.

2. Cook the Noodles

Bring a large pot of salted water to a boil. Cook the egg noodles until just al dente, about 1–2 minutes less than package instructions. Drain promptly and set aside. Slightly undercooked noodles finish tender in the oven, absorbing flavor from the sauce.

3. Sauté Aromatics

In a large sauté pan or Dutch oven, melt butter over medium heat. Add finely diced shallots and minced garlic. Sauté two to three minutes, stirring, until they soften and give off a gentle aroma.

4. Build the Roux & Sauce

Sprinkle in flour while stirring. Cook the mixture for about a minute, letting the raw flour taste disappear. Gradually pour in the half and half, whisking to keep the sauce lump-free.

Add Dijon mustard. Let the mixture come to a gentle simmer. Stir in cheddar cheese by handfuls until the cheese melts and the sauce becomes thick and glossy. Season with salt and black pepper to taste.

5. Fold and Combine

Remove the pan from the heat. Gently fold in the cooked noodles until coated. Add drained tuna, breaking up large flakes with a fork, and stir in the frozen peas. Combine until everything is evenly distributed.

Tip: Don’t overmix. Gentle folding keeps the tuna in generous pieces and noodles intact.

6. Assemble the Casserole

Spoon the noodle mixture into the greased baking dish. Spread into an even layer.

7. Prepare the Panko Topping

In a small bowl, toss panko breadcrumbs with grated Parmesan, lemon zest, and a drizzle of olive oil. Mix thoroughly so every crumb gets coated.

Sprinkle the mixture evenly over the surface of the casserole.

8. Bake

Place the casserole on the center rack of the oven. Bake, uncovered, for 25–30 minutes, until the top is golden brown and the edges bubble.

Cool for five minutes before serving. This rest period helps the sauce set.

9. Finish and Garnish

Top with fresh chopped chives or parsley before serving. Slice and scoop portions for your table.

Flavor Variations and Customizations

Casseroles lend themselves to creativity. Feel free to experiment by adding:

Extra Vegetables: Stir in sautéed mushrooms, carrots, celery, spinach, or broccoli for more nutrition and flavor depth.
Different Toppings: Swap panko for crushed saltines, buttery Ritz crackers, or crushed potato chips. Each brings a unique texture.
Alternative Proteins: Substitute tuna with rotisserie chicken or cooked salmon. Smoked trout or cooked shrimp offer twists for adventurous palates.
Cheese Blends: Use Gruyère, Monterey Jack, or Fontina in place of (or in addition to) Cheddar.

Tips for Best Results

Get the most out of your tuna noodle casserole with these simple techniques:

Shred your own cheese for the creamiest sauce—bagged pre-shredded cheese includes starches that can affect melting.
Use high-quality tuna packed in water for the best texture and fresh flavor.
For a lighter version, reduce the amount of cheese and use low-fat milk in place of half and half (though the texture will be less creamy).
If prepping ahead, assemble the casserole without the topping and store covered in the fridge for up to a day. Add breadcrumbs right before baking. Let the casserole come to room temperature while the oven preheats to avoid uneven heating.

Serving Suggestions

Tuna noodle casserole is a hearty main dish but pairs well with fresh sides. Try:

Crisp mixed green salad with a lemon vinaigrette
Roasted seasonal vegetables such as asparagus or green beans
Warm garlic bread or dinner rolls

For leftovers, the casserole reheats well either covered in the oven or as individual portions in the microwave.

Storage and Reheating Instructions

Proper storage keeps your casserole fresh for several days.

To Store: Allow the casserole to cool fully. Cover tightly or transfer to an air-tight container. Refrigerate up to four days.
To Freeze: For longer storage, freeze the casserole (unbaked or baked and cooled) wrapped in layers of plastic wrap and foil. Freeze up to three months.
To Thaw and Reheat: Thaw overnight in the fridge. Reheat single portions in the microwave, loosely covered, for two to three minutes. For the full casserole, cover with foil and warm in a 350°F oven for 20–30 minutes, removing foil for the last five minutes to re-crisp the topping.
