About This Recipe
This casserole is creamy, cozy, and just a little nostalgic. Every bite gives you tender egg noodles, flaky tuna, sweet peas, and a delicate crunch from a golden breadcrumb topping. The sauce is velvety thanks to nonfat Greek yogurt and a splash of broth, not a drop of cream in sight.
It’s a true weeknight hero—ready in under an hour with pantry staples you probably already have. Plus, it reheats beautifully, so leftovers become tomorrow’s easy lunch.
Why This Recipe Belongs in Your Diet
Tuna is a fantastic lean protein packed with omega-3s, and pairing it with whole grain noodles and fiber-rich peas makes this a balanced, satisfying meal. Using nonfat Greek yogurt instead of creamy soup slashes saturated fat while keeping the texture rich and creamy.
What You’ll Need (Ingredients)
To make this healthier version, we’ll use a few smart swaps to keep things creamy and comforting without the extra fat.
- 8 oz whole wheat egg noodles: These cook quickly and add fiber—look for “no yolk” or whole grain versions.
- 2 cans (5 oz each) light tuna in water, drained: Choose light tuna for less mercury and fat.
- 1 cup frozen peas: Adds color, sweetness, and fiber with no prep.
- 1/2 cup nonfat plain Greek yogurt: Makes the sauce creamy without the fat of mayo or cream.
- 1/2 cup low-sodium chicken or vegetable broth: Helps thin the sauce and keep it flavorful.
- 1/4 cup grated Parmesan cheese: Just enough for a savory punch without overloading fat.
- 1 teaspoon Dijon mustard: Adds a gentle tang that brightens the whole dish.
- 1/2 teaspoon garlic powder: Boosts flavor without extra salt or fat.
- Salt and pepper to taste: Taste and adjust as needed.
- 1/4 cup whole wheat breadcrumbs (optional): For a crispy, golden topping.
