Potato Chip Tuna Casserole (Retro Weeknight Comfort Classic)
1950s Potluck Hero, Back on the Menu 🥫
When I was growing up, payday meant Mom splurged on two small luxuries: a bag of ruffled potato chips and a can of solid‑white albacore. She’d fold them into a bubbling potato chip tuna casserole, slide the dish onto the Formica table, and serve it with dill pickles on the side. The salty chip topping stayed crispy, the noodles baked into a creamy hug, and we kids fought over the corner pieces with the most crunch.
Fast‑forward to today: my teenagers devour this same retro casserole and swear it’s “better than box mac ’n’ cheese.” The magic is that you can assemble it in under 15 minutes with pantry staples—no fancy roux, no chopping veggies—yet it tastes like vintage diner comfort. We’ll jazz it up with sharp cheddar layers, keep the classic cream‑of‑chicken binder, and crown the whole thing with crushed ridged chips. Feel free to swap in peas or mushrooms, but tonight we’re staying loyal to the original that still shows up at church suppers and weeknight tables across America.

Tiny Kitchen Science – Why Potato Chips Stay Crunchy
Ridged chips are fried, driving out moisture and creating a hydrophobic starch‑lipid layer that resists steam. Baking them on top re‑crisp fibers rather than softening—so you get that satisfying shatter at first bite.
