Key Ingredients
The ingredients for this tuna noodle casserole are pretty straightforward, and some you may already have on hand. Here are the main things you'll need:
- Egg noodles. Cooked al dente for the ideal texture.
- Cans of tuna. Light tuna in water works best; choose a good-quality option for plenty of flavor.
- Cheddar cheese & parmesan cheese. Because a good cheesy sauce is always the answer.
- Chicken Broth & Heavy Cream. The dynamic duo for that rich delicious sauce.
- Fresh Vegetables. I always like to try to squeeze as many hidden veggies into a dish as I can as I can! Onion, garlic, mushrooms, and sweet peas bring fresh flavor to this casserole.
- Italian breadcrumbs. These seasoned breadcrumbs create that crispy topping that pairs perfectly with the soft, creamy filling.
- Butter & all-purpose flour. The base for a roux, which thickens the sauce to creamy perfection.
- Lemon zest & dill. Bright, fresh flavors that bring it all together.

This simple recipe comes together quickly. Here's how to make it.
- Cook the egg noodles. Just make cook them according to the package instructions until they're al dente, or still a little firm. They'll continue cooking during the baking process.

- Make the creamy sauce. In a pot, melt butter, whisk in flour, then slowly stir in chicken broth and heavy cream. Let it simmer until thick and creamy, then stir in those melty cheeses. Season with garlic powder, onion powder, and salt to taste.Yum!

Variations & Substitutions
I love a good homemade tuna mac and this recipe has endless options for mixing it up based on what you like or what you have on hand. Here are a few ideas to make it your own.
- Change the protein. Swap tuna for canned chicken for added protein.
- Mix up the veggies. Broccoli, red peppers, kale or spinach, zucchini, or asparagus are all great options. And don't discount frozen veggies - they're great for adding to a casserole and a huge time saver.
- Lighten things up. Use whole milk or half & half if you’re out of heavy cream.

Homemade Cheesy and Creamy Tuna Helper Casserole
Ingredients
- 8 oz plus 1 tablespoon unsalted butter divided
- 12 oz egg noodles
- 1 teaspoon salt
- 1 large onion finely chopped
- 16 oz mushrooms chopped (crimini, shitake, or button all work)
- 4 cloves garlic minced
- ¼ cup white wine
- ½ teaspoon ground black pepper
- 2 teaspoon fresh thyme chopped
- ¼ cup all-purpose flour
- 2 ½ cups chicken broth
- 1 cup half and half
- 1 cup frozen peas
- 3 oz white cheddar cheese shredded
- 3 oz yellow cheddar cheese shredded
- 15 oz canned tuna in water drained (I used 3 5 oz cans)
- 2 cups Italian breadcrumbs
- zest from one lemon
- ½ cup fresh dill chopped
Instructions
- Preheat your oven to 400°F (200°C). Grease a 13x9-inch baking dish with 1 tablespoon of butter and set aside.
- Bring a large pot of salted water to a boil. Add the egg noodles and cook until al dente, according to package instructions. Drain and set aside.
- While the pasta is cooking, melt 4 tablespoons of butter In a large skillet over medium heat. Add the chopped onion and cook, stirring occasionally, until softened but not browned, about 8–10 minutes.
- Increase the heat to medium-high. Add the mushrooms and garlic to the skillet. Cook, stirring occasionally, until most of the mushroom liquid has evaporated, about 4–6 minutes. Pour in the white wine and cook until reduced and the skillet is nearly dry, about 2 minutes. Season with salt, black pepper, and thyme. Remove from heat and set aside.
- In a medium saucepan over medium-low heat, melt the remaining 4 tablespoons of butter. Whisk in the all-purpose flour and cook, whisking constantly, for about 2 minutes until golden and smooth. Gradually whisk in the chicken broth and bring to a boil. Reduce the heat to medium and stir in the half-and-half and both kinds of cheese. Stir until the cheese is fully melted and the sauce is smooth, about 1–2 minutes. Season with salt and black pepper to taste.
- In a large mixing bowl, gently fold together the cooked noodles, mushroom mixture, cheese sauce, frozen peas, and tuna (broken into bite-sized chunks). Taste and adjust seasoning as needed.
- Transfer the mixture to the prepared baking dish, spreading it out evenly. Sprinkle the breadcrumbs over the top.
- Bake in the preheated oven for 15–20 minutes, or until bubbly around the edges and the breadcrumbs are golden.
- Remove the casserole from the oven and let it rest for 5 minutes. Zest the lemon over the top, sprinkle with fresh dill, and serve warm.
