Tuna Noodle Casserole with Potato Chip Topping
This gentle, small-batch tuna noodle casserole with potato chip topping brings back the comfort of classic weeknight meals. It is sized for one or two servings and keeps steps and cleanup to a minimum. The texture is soft and easy to chew, and the potato chips add a nostalgic crunch when you like.

Cooking for one or two should be quick and forgiving. This casserole cooks mostly in one pot, so you spend less time cleaning and more time enjoying a warm, comforting meal.
The recipe is easy to adjust. You can make the noodles very soft, choose low-sodium ingredients, and skip the oven if you prefer a stovetop version that is gentler on digestion.
Ingredients You’ll Need

- 4 ounces egg noodles or small pasta (about 2 cups cooked)
- 1 can tuna in water, drained and flaked (about 5 ounces)
- 1/2 cup frozen peas or soft cooked vegetables
- 1 tablespoon unsalted butter or mild olive oil
- 1 tablespoon all-purpose flour
- 3/4 cup low-sodium chicken or vegetable broth
- 1/4 cup low-fat milk or evaporated milk
- 2 tablespoons cream cheese or a small handful of grated mild cheddar, optional
- 1/3 cup crushed plain potato chips (use unsalted if you are cutting salt)
- Fresh ground black pepper and a small pinch of salt, to taste
You can serve this casserole with a small side of soft bread, mashed potatoes, or steamed vegetables if you like.
Step-by-Step Recipe

- Bring a medium pot of salted water to a boil and cook the egg noodles 1 to 2 minutes longer than package directions for a softer texture. Reserve about 1/4 cup cooking water, then drain the noodles and set them aside.
- In the same pot, melt the butter over medium heat. Stir in the flour and cook 30 to 60 seconds, stirring, to make a light roux.
- Slowly whisk in the low-sodium broth and milk. Whisk until the sauce is smooth and begins to thicken, about 2 to 3 minutes. If it gets too thick, add a splash of the reserved pasta water.
- Stir in the cream cheese or cheese, if using, until melted. Add the drained tuna and peas. Heat gently until everything is warm. Taste and add pepper and a small pinch of salt only if needed.
- Fold the cooked noodles into the sauce until coated. For minimal cleanup, keep the casserole in the same pot and serve from it, or transfer to a small baking dish if you want to crisp the top.
- To keep chips crisp: sprinkle crushed potato chips over each serving just before eating. If you prefer a baked top, sprinkle chips on and bake at 350 F for 8 to 10 minutes, or broil for 1 to 2 minutes while watching closely.
Tips and Easy Variations
Make it easy to chew

FAQ
Can I freeze this casserole?▶
