Step‑by‑Step Instructions for Spicy Miso Tuna Noodle Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 400°F (200°C). While it warms up, grab a 9x13-inch baking dish and lightly grease it with cooking spray or butter to prevent sticking. This preparation will make your Spicy Miso Tuna Noodle Casserole a snap to serve once baked!
Step 2: Cook the Noodles
In a large pot, bring salted water to a rolling boil. Add the egg noodles and cook until they are just very al dente, about 2-3 minutes less than package instructions. Drain the noodles carefully, ensuring they don't overcook, and set them aside while you prepare the flavorful sauce.
Step 3: Sauté the Aromatics
Return the same pot to medium heat and melt 4 tablespoons of unsalted butter. Once melted, add the chopped white and pale green parts of the scallions along with the finely diced onion and minced garlic. Sauté for 6-8 minutes or until softened and fragrant, stirring frequently to prevent browning.
Step 4: Make the Roux
Sprinkle 1/4 cup of all-purpose flour over the sautéed vegetables, stirring well to combine. Allow it to cook for about 2 minutes until it turns a pale golden color, stirring continuously to remove any lumps. Gradually whisk in 2 cups of water (or low-sodium chicken broth), bringing the mixture to a boil until it thickens, which should take about 5 minutes.
Step 5: Create the Creamy Mixture
Once thickened, remove the pot from heat and stir in the zest of one lemon, 1 package of cream cheese, 1 cup of shredded cheese, 3 tablespoons of miso, 2-3 tablespoons of chili sauce, 1 tablespoon of chicken bouillon paste, and 2 tablespoons of soy sauce. Mix everything until perfectly smooth and creamy, embracing all those umami flavors.
Step 6: Combine Ingredients
Next, gently fold in the cooked egg noodles, 2 cans of drained tuna, and 1 cup of frozen peas into the creamy mixture. Be careful not to break apart the noodles or tuna too much. Season with salt and pepper to taste, ensuring a balanced flavor before transferring the entire mixture into the greased baking dish.
Step 7: Add the Crunchy Topping
Evenly sprinkle a generous layer of crushed potato chips on top of the casserole. This will provide a delightful crunch and contrast to the creamy goodness below. Make sure to cover the entire surface for that perfect golden finish in the oven.
Step 8: Bake to Perfection
Place the prepared casserole in the preheated oven and bake for 15-20 minutes or until hot and bubbly. The potato chips should turn golden brown, offering a beautiful visual cue that your comforting Spicy Miso Tuna Noodle Casserole is almost ready.
Step 9: Finish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. For an extra touch, garnish with additional lemon zest and the green parts of the scallions before serving. This delightful dish is now ready to warm up your weeknight dinner!

Spicy Miso Tuna Noodle Casserole Recipe FAQs
How do I select the right miso for this recipe?
For the best flavor in your Spicy Miso Tuna Noodle Casserole, I recommend using yellow or white miso, as these varieties have a milder sweetness and balance well with the spicy elements in the dish. You can find miso at most grocery stores, often in the refrigerated section near tofu or Asian ingredients. If you need a substitute, tahini can work in a pinch, but it won't deliver the same umami depth.
How should I store leftovers from the casserole?
Leftover Spicy Miso Tuna Noodle Casserole can be stored in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, I suggest reheating in the oven for the best texture. Simply cover your dish with aluminum foil and warm it at 350°F (175°C) until heated through, about 15-20 minutes. You can microwave individual portions if you're in a hurry!
Can I freeze the casserole for later?
Absolutely! You can freeze your assembled Spicy Miso Tuna Noodle Casserole before adding the potato chip topping. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn, and it will keep well for up to 2 months. When you're ready to bake it, thaw it overnight in the refrigerator, then top with crushed chips and bake at 350°F (175°C) until hot and bubbly.
What should I do if my sauce is too thick?
If you find that your sauce for the Spicy Miso Tuna Noodle Casserole is thicker than you'd like, simply whisk in a little more water or chicken broth over low heat until it reaches your desired consistency. Be sure to do this gradually so it doesn’t become too runny. The goal is a smooth, creamy sauce that easily coats the noodles.
Is this casserole suitable for those with dietary restrictions?
While this Spicy Miso Tuna Noodle Casserole contains several ingredients that may not align with all dietary needs, it can be modified to accommodate some restrictions. For a gluten-free version, simply use gluten-free pasta and ensure your miso and soy sauce are gluten-free as well. For dairy-free options, substitute the cream cheese and cheese with cashew cream or a dairy-free cheese alternative, and use olive oil instead of butter. Always check labels for allergen information to ensure safety!
How can I enhance the nutritional value of this casserole?
To boost the nutritional profile of your Spicy Miso Tuna Noodle Casserole, consider adding extra vegetables such as spinach, bell peppers, or even shredded carrots before folding in the noodles and tuna. Not only will this add color and texture, but you'll also sneak in some healthy vitamins and minerals. Plus, these veggies will cook down nicely in the oven, blending perfectly with the flavors of the dish.
