Ingredients
This casserole leans on pantry staples while still showcasing fresh flavors. The tuna gives a salty, meaty backbone, while egg noodles provide a comforting chew. A light béchamel made with milk, butter, and a dash of flour creates a velvety coating, and the blend of herbs and vegetables adds brightness. Together they form a harmonious, hearty breakfast that’s both satisfying and nourishing.
Main Ingredients
- 2 (5‑oz) cans solid white tuna, drained
- 8 oz egg noodles
- 1 cup frozen peas, thawed
Sauce & Creamy Base
- 2 tbsp unsalted butter
- 2 tbsp all‑purpose flour
- 1 ½ cups whole milk, warmed
- ½ cup shredded sharp cheddar cheese
Seasonings & Topping
- 1 tsp Dijon mustard
- ½ tsp dried thyme
- ¼ tsp freshly ground black pepper
- ¼ cup panko breadcrumbs
- 1 tbsp melted butter (for topping)
The butter‑flour roux forms the foundation of a smooth béchamel, while milk adds richness without heaviness. Dijon mustard and thyme lend a subtle zing that lifts the tuna, and the cheddar introduces a mellow melt. Finally, the panko‑butter topping creates a golden, crunchy crown that contrasts beautifully with the creamy interior.
Step-by-Step Instructions
Preparing the Noodles & Tuna
Bring a large pot of salted water to a rolling boil. Add the egg noodles and cook according to package directions until al dente, usually 7–8 minutes. Drain, rinse briefly with cool water to stop cooking, and set aside. While the noodles are cooking, break the tuna into bite‑size flakes and set aside in a mixing bowl.
Making the Creamy Béchamel
In a medium saucepan melt 2 tbsp unsalted butter over medium heat. Sprinkle 2 tbsp all‑purpose flour over the melted butter, whisking constantly for 1–2 minutes to create a blond roux—this eliminates any raw flour taste. Gradually whisk in the 1 ½ cups warm whole milk, stirring until the mixture thickens and coats the back of a spoon, about 4 minutes. Reduce the heat to low and stir in ½ cup shredded sharp cheddar, 1 tsp Dijon mustard, and ½ tsp dried thyme. Season with ¼ tsp freshly ground black pepper and a pinch of salt. The sauce should be glossy and smooth.
Assembling the Casserole
- Combine Base. In a large mixing bowl, gently fold the cooked noodles, flaked tuna, and 1 cup thawed peas together. Pour the béchamel over the mixture and stir until everything is evenly coated.
- Transfer to Dish. Lightly grease a 9‑x‑13‑inch baking dish. Spoon the noodle‑tuna mixture into the dish, spreading it into an even layer. The dish should be about 1‑inch thick for even baking.
- Prepare Topping. In a small bowl combine ¼ cup panko breadcrumbs with 1 tbsp melted butter. Sprinkle the mixture evenly over the top of the casserole, ensuring full coverage for a uniform crust.
- Initial Bake. Place the dish on the middle rack of a preheated 375°F (190°C) oven. Bake uncovered for 20 minutes, or until the topping turns golden brown and the sauce bubbles at the edges.
- Rest & Serve. Remove the casserole from the oven and let it rest for 5 minutes. This short rest allows the sauce to set, making slicing easier. Garnish with a sprinkle of fresh parsley if desired, then serve hot.
Tips & Tricks
Perfecting the Recipe
Al Dente Noodles. Cook the noodles just shy of fully done; they’ll finish cooking in the oven, preventing a mushy texture.
Room‑Temp Tuna. Flake the tuna while it’s still slightly warm from the can; it mixes more evenly with the sauce.
Even Breadcrumb Spread. Toss the panko with melted butter until lightly coated; this ensures a uniform golden crust.
Rest Before Cutting. Let the casserole sit for a few minutes after baking; it firms up and slices cleanly.
Flavor Enhancements
Add a splash of fresh lemon juice to the sauce just before baking for a bright pop. A pinch of smoked paprika in the breadcrumb topping introduces a gentle smoky depth. For extra richness, stir in a tablespoon of cream cheese into the béchamel while it’s still warm.
Common Mistakes to Avoid
Skipping the resting step results in a runny casserole that falls apart on the plate. Over‑baking can dry out the noodles; keep an eye on the oven after 18 minutes and remove when the topping is just golden.
Pro Tips
Use Fresh Herbs. Chopped chives or dill added at the end brighten the dish and complement the tuna.
Invest in a Thermometer. Ensuring the internal temperature reaches 165°F guarantees safe consumption without overcooking.
Pre‑Toast Breadcrumbs. Lightly toast panko in a dry skillet before mixing with butter for an extra crunchy texture.
Batch Cook Noodles. Cook a larger batch of noodles and freeze in portions; they reheat perfectly for future casseroles.
Variations
Ingredient Swaps
Replace tuna with canned salmon or shredded chicken for a different protein profile. Swap peas for sweet corn or diced carrots to change the color palette. For a richer sauce, use half‑and‑half instead of milk, or incorporate a handful of grated Gruyère cheese.
Dietary Adjustments
Use gluten‑free pasta and gluten‑free breadcrumbs for a safe gluten‑free version. Substitute the dairy milk and butter with oat milk and a plant‑based margarine for a vegan-friendly casserole, and choose a dairy‑free cheese alternative. For a low‑carb take, replace noodles with spiralized zucchini.
Serving Suggestions
Pair the casserole with a crisp arugula salad tossed in a lemon vinaigrette, or serve alongside roasted baby potatoes for extra heartiness. A side of fresh sliced tomatoes adds acidity, while a dollop of Greek yogurt on each plate offers a cool contrast to the warm casserole.
Storage Info
Leftover Storage
Allow the casserole to cool completely, then transfer to an airtight container. It keeps well in the refrigerator for 3–4 days. For longer preservation, portion into freezer‑safe bags or containers, lay flat, and freeze up to 3 months. Label with date and reheat within the recommended timeframe for best flavor.
Reheating Instructions
To reheat, preheat the oven to 350°F (175°C), cover the casserole loosely with foil, and bake for 15–20 minutes until steaming hot. This method preserves the creamy interior and prevents the breadcrumbs from becoming soggy. In a pinch, microwave individual portions on medium power for 2–3 minutes, adding a splash of milk and stirring halfway through.
