Cheesy Tuna Noodle Casserole with Potato Chips
This small-batch tuna noodle casserole with potato chips is a cozy, low-fuss meal for one or two, with soft noodles, flaked tuna, a mild cheese sauce, and a crunchy potato chip topping.

Making a dish just for one or two helps reduce waste and keeps portions gentle for digestion. This casserole is baked in a single small dish, so there is little fuss and fewer pans to wash.
The sauce is mild and creamy, and you can make it lighter or softer by using low-fat milk or stirring in plain yogurt at the end. The potato chip topping gives crunch without complex prep.
Ingredients You’ll Need

- 4 ounces (about 1 cup) egg noodles or small pasta
- 1 tablespoon unsalted butter
- 1 tablespoon all-purpose flour
- 3/4 cup low-fat milk or unsalted broth for a lighter option
- 2 tablespoons plain yogurt or reduced-fat sour cream
- 1/2 cup shredded mild cheddar cheese
- 1 (5 ounce) can tuna in water, drained and flaked
- 1/4 cup frozen peas or soft cooked vegetables, optional
- 1/2 cup crushed plain potato chips, plus a few extra for garnish
- Salt and black pepper to taste – use sparingly if you reduce sodium
You can serve this creamy casserole with a small side of soft bread, mashed potatoes, or a spoonful of cooked rice if you like.
Step-by-Step Recipe

- Preheat the oven to 350 F and set a small ovenproof dish or 8-inch skillet nearby.
- Cook the egg noodles in salted water until very tender, about 6 to 8 minutes. Drain and return to the pot.
- While the pasta cooks, melt butter over medium heat in a small saucepan. Stir in the flour and cook 30 seconds to 1 minute to make a roux.
- Slowly whisk in the milk or unsalted broth until smooth. Bring to a gentle simmer and cook until slightly thickened, about 2 to 3 minutes.
- Remove from heat. Stir in the yogurt, half the cheese, and a few grinds of black pepper. Taste and add a pinch of salt only if needed.
- Fold the flaked tuna and peas into the drained noodles. Pour the cheese sauce over the noodles and mix gently so the textures stay soft.
- Transfer the mixture to your baking dish. Sprinkle the top with the remaining cheese and then the crushed potato chips. Press the chips down slightly so they stick.
- Bake for 12 to 15 minutes, until the edges bubble and the chips are lightly golden. If you like a softer top, bake 10 minutes and cover loosely with foil for the last few minutes.
- Let rest 5 minutes before scooping. Garnish with a few whole chips if you like and serve warm.
Tips and Easy Variations
Texture and chewing
- Soften for easier chewing by cooking the noodles a minute or two longer than package directions
- Mash slightly with a fork before serving to reduce chewing effort
- Let the casserole rest so textures soften and flavors meld
Make it lighter
- Use low-fat milk or unsalted broth instead of whole milk
- Swap plain yogurt for sour cream for a gentler sauce texture
- Reduce the cheese to 1/3 cup if you prefer a lighter dish
Dietary swaps
- Reduce salt by choosing unsalted butter and low-sodium milk or broth
- Try a vegetarian option with canned chickpeas or drained creamed corn instead of tuna
- Swap the topping for crushed unsalted crackers or toasted panko for less salt
Gentle cooking reminders
- Cook noodles extra soft for easier chewing
- Assemble ahead and refrigerate, adding chips just before baking for best crunch
- Choose unsalted or low-sodium ingredients when needed
Storage and Leftovers
Fridge
Cool leftovers to room temperature, then refrigerate in a covered container for up to 3 days. Add fresh crushed chips on top before serving if the original topping softens.
Freezer
You can freeze the casserole pre-baked for up to 1 month. Thaw overnight in the refrigerator before baking until hot. Chips will lose crispness, so plan to add fresh chips before serving.
Reheating
Reheat gently in a small ovenproof dish at 325 F until warmed through, or microwave in 30 second bursts until hot. Add a few fresh crushed chips for crunch after reheating.

Give this tuna noodle casserole with potato chips a try when you want a soft, small-portion meal with a touch of crunch. It is simple to make and easy to adapt for gentler digestion.
This small-batch casserole is perfect for cooking for one or two with minimal cleanup and familiar comforting flavors.
