Ingredients
| Quantity | Ingredient |
|---|---|
| 2/3 cup | Celery, diced |
| 2/3 cup | Onion, finely chopped |
| 1/4 cup | Green bell pepper, diced |
| 1 ½ tbsp | Butter (for sautéing vegetables) |
| 3 tbsp | Butter (for sauce) |
| 1/2 cup | Flour (all-purpose) |
| 1 ½ tsp | Salt |
| 2 cups | Milk (preferably whole milk, or 2%) |
| 3 cans (5 oz each) | Tuna in water, drained |
| 3/4 cup | Salted cashews, roughly chopped |
| 2 cups | Chow mein noodles |
| To taste | Black pepper, freshly ground |
Instructions
Step 1: Preparing the Vegetables
Begin by gathering all your fresh vegetables: celery, onion, and green bell pepper. Rinse the celery stalks under cool running water to remove any dirt or debris, then trim off the ends using a sharp knife. Slice the celery into thin, uniform pieces—about 1/4 inch thick—so they cook evenly. Next, peel and finely chop the onion; aim for small dice to ensure they soften quickly and blend seamlessly into the sauce. For the green bell pepper, core and seed it thoroughly to remove any bitterness, then dice into small squares similar in size to the celery pieces. These vegetables provide a vibrant base for the casserole, offering crunch, sweetness, and freshness that complement the richness of the tuna and creamy sauce.
Step 2: Sautéing Vegetables
Heat 1 ½ tablespoons of butter in a large skillet over medium heat. Once melted and shimmering, add the prepared celery, onion, and green bell pepper. Sauté the vegetables, stirring frequently with a spatula or wooden spoon, until they become tender and translucent—about 5 to 7 minutes. This process releases their natural flavors and softens their texture, ensuring they meld smoothly into the casserole. Season lightly with a pinch of salt if desired, to enhance their flavor. Once cooked, transfer the sautéed vegetables to a small bowl or plate and set aside to cool slightly. This step ensures the vegetables are flavorful and tender, adding layers of texture and taste to your final dish.
Step 3: Making the Roux for the Sauce
In a medium saucepan, melt 3 tablespoons of butter over medium heat. When the butter has fully melted and starts to shimmer, add the flour, whisking vigorously to create a smooth, lump-free paste called a roux. Continue whisking for about 1-2 minutes to cook out the raw flour taste, but do not let it brown excessively. The roux will serve as the thickening agent for your creamy sauce, so consistency and smoothness are crucial at this stage. This technique forms the foundation of your béchamel-style base, giving the casserole its luscious texture.
Step 4: Creating the Creamy Base
Remove the saucepan from heat momentarily, then slowly pour in the milk while continuously whisking to prevent lumps from forming. Start with a small amount and gradually add more as the mixture begins to thicken, maintaining a steady stream of milk. Once all the milk is incorporated, return the saucepan to medium heat. Continue whisking until the mixture comes to a gentle boil. As it boils, the sauce will thicken further—this is a critical stage, so keep stirring to prevent burning or sticking. Allow the sauce to boil for about 1 minute, or until it reaches your desired thickness. You’re aiming for a velvety, smooth consistency that will coat the ingredients beautifully once combined.
Step 5: Incorporating Tuna and Vegetables
Gently fold in the drained tuna, breaking it apart into smaller chunks as you mix. Add the sautéed vegetables, ensuring they are evenly distributed throughout the sauce. Mix carefully but thoroughly to marry the flavors—this combination is the heart of your casserole. The tuna adds a savory, protein-rich element, while the vegetables contribute crunch, sweetness, and freshness, balancing the richness of the sauce. Continue stirring until everything is well coated and the mixture is heated through, about 2-3 minutes.
Step 6: Incorporating Cashews and Chow Mein Noodles
Add the salted cashews and 1 cup of chow mein noodles to the mixture. Season with freshly ground black pepper to taste—start with a small amount and adjust as needed. Stir everything together gently, ensuring the cashews and noodles are evenly distributed. The salted cashews introduce a delightful crunch and a nutty flavor that complements the tuna and creamy sauce, while the chow mein noodles add an irresistible crispy texture once baked.
Step 7: Preparing the Baking Dish
Preheat your oven to 350°F (175°C). Grease a 1 ½-quart baking dish thoroughly with butter to prevent sticking and promote even browning. Pour the tuna, vegetable, and sauce mixture into the prepared dish, spreading it out evenly with a spatula or the back of a large spoon. This level surface ensures uniform cooking and a neat presentation once baked.
Step 8: Adding the Crunchy Topping
Sprinkle the remaining chow mein noodles evenly over the top of the casserole. This crispy topping will develop a golden-brown crust during baking, providing a contrasting texture to the creamy interior. For extra flavor, you can sprinkle a little additional salt or pepper over the noodles, or even a touch of shredded cheese if you prefer a cheesier version.
Step 9: Baking to Perfection
Place the casserole in the preheated oven and bake for approximately 30 minutes. During baking, the noodles will crisp up, the casserole will heat through, and the flavors will meld into a harmonious dish. Keep an eye on the top—once it turns a lovely golden brown and becomes crispy, it’s ready to enjoy. If you notice the top browning too quickly, tent the dish with aluminum foil to prevent burning while the interior finishes cooking.
Step 10: Serving
Once baked, carefully remove the casserole from the oven and transfer it onto a cooling rack or trivet. Allow it to rest for 5 minutes; this helps the casserole set slightly, making serving easier. Garnish with optional chopped parsley or sliced green onions for a fresh, vibrant touch. Serve hot with your favorite side dishes, such as a crisp green salad, steamed vegetables, or warm crusty bread to soak up the delicious sauce. Enjoy every bite of this comforting, flavorful dish that combines a variety of textures and tastes in perfect harmony.
Preparation Tips
- Vegetable prep: Use a sharp knife for clean cuts, and consider prepping all vegetables ahead of time to streamline the process.
- Cheese addition: For a cheesy upgrade, sprinkle shredded cheddar, Monterey Jack, or mozzarella over the casserole just before baking. Cover loosely with foil if you want a softer cheese melt or leave uncovered for a crispy crust.
- Cashew selection: Use salted cashews for added flavor, but you can opt for unsalted if you prefer a less salty dish. Toast the cashews lightly in a dry skillet before adding for an extra depth of flavor.
- Cooking the noodles: If you prefer a softer topping, you can briefly toast the chow mein noodles in a bit of butter before sprinkling over the casserole.
