Step‑by‑Step Instructions for Healthy Tuna Noodle Casserole

Step 1: Preheat and Prepare Baking Dish
Preheat your oven to 375°F (190°C). While it’s heating, prepare a 9×13-inch baking dish by lightly coating it with non-stick spray. This ensures an easy release once your Healthy Tuna Noodle Casserole is baked to bubbly perfection.

Step 2: Cook the Noodles
Bring a large pot of salted water to a boil and cook the dry whole-wheat egg noodles for about 6-7 minutes, or until very al dente. Drain the noodles in a colander and set them aside, as they will continue cooking in the casserole later.

Step 3: Sauté Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the sliced baby bella mushrooms and finely chopped yellow onion, sautéing for approximately 8 minutes until soft and translucent. Keep an eye on them as they caramelize, stirring occasionally to prevent sticking.

Step 4: Add Aromatics
Stir in the minced garlic and fresh thyme leaves, cooking for another minute until fragrant. The mixture should start filling your kitchen with a lovely aroma, indicating it’s time to move to the next step in creating your Healthy Tuna Noodle Casserole.

Step 5: Make the Sauce
Add 2 tablespoons of unsalted butter to the skillet, melting it fully. Sprinkle in 3 tablespoons of all-purpose flour, cooking for about 2 minutes while constantly stirring to create a roux. This step is essential for the creamy texture you desire in your casserole.

Step 6: Incorporate Liquids
Gradually whisk in 2 cups of vegetable broth, bringing the mixture to a gentle boil. Once boiling, reduce the heat to simmer, then whisk in 2 cups of whole milk along with 2 teaspoons of Dijon mustard, 1 teaspoon of kosher salt, ½ teaspoon of black pepper, and ¼ teaspoon of celery seed for added flavor.

Step 7: Thicken the Sauce
Allow the sauce to simmer for 3 minutes, stirring frequently until it thickens slightly. Once ready, stir in half of the grated sharp white cheddar cheese, making sure it melts into the sauce, contributing to the delightful creaminess of your Healthy Tuna Noodle Casserole.

Step 8: Combine Ingredients
In a large mixing bowl, combine the thickened sauce with the cooked noodles, drained tuna, and thawed green peas. Gently fold everything together, ensuring the pasta is well coated and the ingredients are evenly distributed.

Step 9: Transfer and Top
Pour the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining sharp white cheddar cheese on top and add ½ cup of panko breadcrumbs, which will provide a crunchy topping once baked.

Step 10: Bake and Broil
Place the baking dish in the preheated oven and bake for 15 minutes or until the casserole is bubbly and the cheese is melted. For an extra crispy top, turn on the broiler for 2 minutes, watching closely to avoid burning.

Step 11: Rest Before Serving
Once baked, remove the casserole from the oven and let it rest for 5-10 minutes. This helps the Healthy Tuna Noodle Casserole set, making it easier to serve. Consider garnishing with fresh thyme for a pop of color before enjoying!

How to Store and Freeze Healthy Tuna Noodle Casserole

Healthy Tuna Noodle Casserole Recipe FAQs

How do I choose the right tuna for my casserole?
Absolutely! For the healthiest options, select lower mercury tuna varieties such as skipjack or albacore. Look for tuna packed in water without added sodium for a wholesome choice. It’s best to avoid darker tuna types as they usually contain higher levels of mercury.

What if my casserole has cooled down after baking?
No worries! If your casserole has cooled, you can simply reheat it in the oven. Cover it with aluminum foil to keep moisture in and heat it at 350°F (175°C) for 20-25 minutes. This helps maintain the creamy texture you love while ensuring it heats through evenly.

How long can I store leftovers of Healthy Tuna Noodle Casserole?
I recommend storing any leftovers in an airtight container in the refrigerator for up to 4 days. Let the casserole cool completely before sealing it up to help maintain freshness and prevent sogginess.

Can I freeze Healthy Tuna Noodle Casserole?
Absolutely! You can freeze your casserole for up to 3 months. To do so, cool it completely after baking, then cut it into individual portions. Wrap each serving tightly in plastic wrap or store them in freezer-safe containers. Thaw overnight in the fridge before reheating to enjoy that comforting taste again!

What can I add or substitute if I have dietary restrictions?
Very good question! If you’re looking for alternatives, you can easily swap whole wheat noodles for gluten-free pasta. For dairy-free options, replace whole milk with unsweetened cashew milk and use a dairy-free cheese. Additionally, feel free to incorporate veggies like spinach or bell peppers for added nutrition; just make sure to sauté them briefly to soften before mixing them into the casserole.
