Step‑by‑Step Instructions for Healthy Tuna Noodle Casserole
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) and generously coat a 9×13-inch baking dish with non-stick spray to ensure an easy release after baking. Setting up your dish now will save time later, allowing you to focus on making your Healthy Tuna Noodle Casserole as delicious as possible.
Step 2: Cook the Noodles
In a large pot, cook the whole-wheat egg noodles until al dente according to the package instructions, usually about 7–9 minutes. Drain the noodles well and return them to the pot without heat. This will keep them warm and ready for the smooth, creamy sauce you’re about to create, adding a perfect base for your casserole.
Step 3: Sauté the Vegetables
Heat the olive oil in a large skillet over medium-high heat, then add the sliced baby bella mushrooms and diced yellow onion. Sauté for about 8 minutes, stirring occasionally, until the vegetables are softened and lightly golden. This will infuse the dish with a rich, savory flavor, paving the way for the creamy goodness to come.
Step 4: Add Garlic and Thyme
Once your mushrooms and onions are softened, stir in the minced garlic and fresh thyme leaves, cooking for an additional minute. You’ll notice the fragrant aroma filling your kitchen, letting you know it’s time to move on to thickening the sauce for your Healthy Tuna Noodle Casserole.
Step 5: Make the Roux
Add the unsalted butter to the skillet and melt it completely. Once melted, sprinkle the all-purpose flour over the mixture to form a roux, stirring constantly for about 2 minutes. This step is essential for achieving a creamy texture in your sauce, so keep stirring until it lightly bubbles but doesn’t brown.
Step 6: Create the Sauce
Gradually whisk in the vegetable broth, bringing the mixture to a boil, then reduce the heat to low to maintain a gentle simmer. Allow the sauce to thicken for about 3-4 minutes, stirring occasionally until it coats the back of a spoon. This will create a rich and savory base for your casserole.
Step 7: Stir in Dairy and Seasoning
Slowly whisk in the whole milk, Dijon mustard, kosher salt, black pepper, and celery seed, allowing the mixture to simmer for another 3 minutes until thickened. The creamy sauce will bring depth and flavor to your Healthy Tuna Noodle Casserole, making it irresistibly comforting.
Step 8: Cheese and Citrus Touch
Remove the skillet from heat and stir in half of the sharp white cheddar cheese until it melts. Then, mix in the fresh lemon juice and zest. This brightens the dish beautifully, balancing the richness of the cheese with the zestful tang of lemon.
Step 9: Combine Ingredients
Combine the creamy sauce with the cooked noodles, drained canned tuna, and thawed green peas in the pot, mixing well to ensure every noodle is coated in that luscious sauce. This step incorporates all the goodness, creating a hearty and flavorful filling for your casserole.
Step 10: Transfer and Top
Pour the entire mixture into the prepared baking dish, spreading it evenly. Top it off with the remaining sharp white cheddar cheese followed by an even layer of panko breadcrumbs. The breadcrumbs will form a delightful, crispy topping that contrasts the creamy filling of your Healthy Tuna Noodle Casserole.
Step 11: Bake and Broil
Bake the casserole in your preheated oven for about 15 minutes until it is bubbly and heated through. For a perfectly golden top, switch to broil for an additional 2 minutes, keeping a close eye to prevent burning. The result will be a beautiful, comforting dish ready to serve.
Step 12: Cool and Serve
Allow the casserole to stand for 5-10 minutes before serving. This rest period lets the flavors meld beautifully and ensures each portion holds together when you serve it. Feel free to garnish with fresh thyme leaves for an extra burst of color and flavor!
