Tuna Noodle Casserole – Hungarian Chef

by Rebecca Novak published on September 17, 2025

Tuna noodle casserole is a comforting dish that welcomes a variety of sides and accompaniments. My favorites include a crisp garden salad with a tangy vinaigrette, roasted vegetables drizzled with olive oil, or a warm garlic bread on the side. 

Each of these can complement the creamy texture of the casserole, adding a fresh contrast. You could also pair it with a light, citrusy beverage or a simple iced tea to balance the flavors. Think of what you love most and mix it up!

Tuna Noodle Casserole

Welcome to my delicious world of healthy cooking! Let’s dive into a dish that holds a special place in my heart—healthy tuna noodle casserole. It’s a classic comfort food that has been reimagined to be nutritious without sacrificing flavor. 

You might remember the childhood memories of diving into a warm, cheesy casserole right out of the oven. Today, I promise to show you how to recreate that nostalgic dish, but with a healthier twist.

Many people think healthy eating is all about bland flavors and endless salads. I’m here to break that stereotype. This casserole is anything but boring. With a blend of wholesome ingredients, it’s creamy, satisfying, and just downright delicious. Plus, it’s quick to prepare, making it a go-to option for busy weeknights or family gatherings.

What is Healthy Tuna Noodle Casserole?

Healthy tuna noodle casserole is a modern adaptation of a classic comfort dish. Traditionally rich and creamy, today’s version focuses on nutritious ingredients without sacrificing taste. We incorporate whole wheat pasta, protein-rich tuna, and fresh vegetables into a lighter, yet still creamy base. This casserole is made to be family-friendly and easy on the waistline.

While every recipe has its own spin, the heart of tuna noodle casserole remains the same—tender pasta combined with tuna, a creamy sauce, and often a crunchy topping. What sets this recipe apart is the use of Greek yogurt instead of excessive heavy cream, and the introduction of fresh greens and colorful veggies.

What is the Flavor Profile of This Dish?

Imagine a warm hug of flavors. The comforting taste of creamy sauce pairs beautifully with the mild, savory notes of tuna. Adding vegetables like bell peppers and spinach brings a refreshing crunch while giving a pop of color. The subtle seasoning of Italian herbs and a hint of Dijon mustard deepen the flavor profile, lifting it from ordinary to extraordinary.

Overall, the dish is both savory and satisfying. A little kick from red pepper flakes (if you like) adds excitement, while the fresh vegetables balance the richness of the yogurt and cheese. Each bite is an experience, reminiscent of home-cooked meals from childhood but even better, thanks to that health-conscious twist.

What Makes This Recipe Different From Other Healthy Tuna Noodle Casseroles?

What elevates this healthy tuna noodle casserole from the typical versions is the use of whole ingredients and a lighter approach. Many traditional recipes rely heavily on creamy soups and processed ingredients. My version opts for Greek yogurt and low-sodium chicken stock, delivering similar creaminess with fewer calories.

Here’s how this recipe truly shines:
Fresh Ingredients: We use fresh vegetables like spinach and bell peppers, giving it a vibrant nutrition boost.
Whole Grains: Using whole wheat pasta不仅增加了纤维,还增加了饱腹感。
Greek Yogurt: It replaces heavy cream and adds protein along with a rich texture.
Balanced Flavors: The blend of spices and ingredients creates a cohesive dish that hits all the right notes.

Ingredients You’ll Need

To whip up this delightful casserole, gather the following ingredients:

2 cups whole wheat rigatoni or penne (uncooked)
8-12 ounces flaked chunk light tuna in water (drained)
1 cup low-sodium chicken stock
1/4 cup plain, full-fat Greek yogurt
1/4 cup whole milk (or unsweetened almond milk if you prefer)
1 cup finely chopped onion
1 cup diced sweet bell peppers (any color will do)
2 1/2 cups frozen green peas
4 cups baby spinach, tightly packed
1 teaspoon freshly ground black pepper
1 teaspoon Italian seasoning
2 tablespoons Dijon mustard
1/4 cup shredded sharp cheddar cheese
1/4 teaspoon crushed red pepper flakes (optional for a little heat)

How to make Tuna Noodle Casserole

Step-by-Step Directions

Step 1: Cooking the Pasta

First things first, bring a large pot of salted water to boil. Add your whole wheat pasta to the pot and cook according to the package directions until al dente. Once done, drain and set aside. This will not only help the pasta maintain its firmness but also absorb the casserole’s flavors.

Step 2: Sauté the Vegetables

In a large skillet, heat a splash of olive oil over medium heat. Add the chopped onion and sauté until it becomes translucent. This should take around 5 minutes. Next, toss in the diced bell peppers and cook for an additional 3-4 minutes until they soften. Then, add the frozen peas and spinach, stirring until the greens wilt and everything is well combined.

Step 3: Create the Sauce

In a separate mixing bowl, whisk together the Greek yogurt, chicken stock, whole milk, Dijon mustard, Italian seasoning, crushed red pepper flakes, and black pepper. This creamy mixture is what binds everything together in the casserole.

Step 4: Combine Everything

In a large mixing bowl, combine the cooked pasta, sautéed vegetables, and drained tuna. Pour the yogurt sauce over the top and mix gently until every ingredient is evenly coated. Collective harmony is what we aim for here!

Step 5: Assemble and Bake

Preheat your oven to 350°F (175°C). Transfer the mixture into a greased baking dish, spreading it out evenly. To top it off, sprinkle shredded cheddar cheese over the casserole. Now it’s ready for baking. Cover with foil and bake for about 20 minutes. Remove the foil and let it bake for an additional 10 minutes until the cheese is bubbly and golden brown.

Step 6: Rest and Serve

After baking, let the casserole cool for a few minutes before serving. This waiting period allows the flavors to settle, making each forkful even tastier. Serve it warm and enjoy!

Tips on Making Healthy Tuna Noodle Casserole

Use Fresh Veggies: Fresh vegetables not only enhance the flavor but also increase the nutritional value of the dish. Consider adding broccoli or carrots for extra crunch.

Adjust the Creaminess: If you prefer a creamier casserole, feel free to increase the amount of Greek yogurt or use a small amount of cream, but keep it minimal for health.

Season to Taste: Taste the mixture before baking. Depending on your preference, you may want to adjust the seasoning. A little more pepper can kick things up a notch!

Light on the Cheese: If you’re watching your fat intake, use less cheese or skip the cheese topping altogether. The casserole will still taste delicious.

Batch Cooking: Make a double batch and freeze half for a busy night. It reheats well and you’ll be thankful for having this wholesome meal on hand.

How Can I Store This Healthy Tuna Noodle Casserole?

Storing your leftover casserole is simple. Let it cool down completely before transferring it to an airtight container. The casserole can remain in the refrigerator for up to 3 days. For longer storage, consider freezing it. Use a freezer-safe container and it can last up to 3 months.

To reheat, simply thaw overnight in the refrigerator if frozen and bake it in the oven at 350°F (175°C) until heated through. A little addition of milk can help restore creaminess upon reheating.

Substitute Options for the Ingredients

Sometimes, you may not have all the ingredients on hand. Here are some substitute options:

Whole Wheat Pasta: If you don’t have whole wheat pasta, regular pasta works just fine, or you can opt for gluten-free pasta to accommodate dietary needs.

Greek Yogurt: In case Greek yogurt is not available, low-fat sour cream or cottage cheese can also be used as substitutes for creaminess.

Tuna: Not a fan of tuna? You can swap it with canned chicken or even white beans for a hearty vegetarian option.

Dijon Mustard: If you’re out of Dijon mustard, yellow mustard or even a bit of mayonnaise can provide similar tanginess.
