Method
Boil the Trash Base
1
Bring a large pot of heavily salted water to a rolling boil. Cook macaroni according to package directions until al dente, then drain and set aside.
Build the Tuna Mixture
2
While pasta cooks, flake the drained tuna into a large mixing bowl. Fold in the mayonnaise and diced onion until evenly combined.
Make the Cheese Sauce
3
In a saucepan over medium heat, melt the butter. Add the milk and bring to a gentle simmer. Gradually whisk in the grated cheddar cheese until silky and smooth. Season with salt and black pepper.
Assemble and Top
4
Preheat your oven to 200°C (400°F). In a large baking dish, fold the cheese sauce through the drained macaroni, then fold in the tuna mixture until everything is married together. Taste and adjust seasoning.
5
In a small bowl, toss the crushed potato chips with the melted butter and breadcrumbs. Scatter this crunchy crown evenly over the macaroni.
Bake and Finish
6
Slide the dish into the preheated oven and bake for 20 minutes until the top is golden and crispy and the edges are bubbling.

Safety & Storage
Cooking Temperature
Bake assembled casserole at 200°C (400°F) for full 20 minutes to ensure dairy and fish components reach safe internal temperature. Edges should bubble and top must turn golden.
If rotisserie chicken is added per the variant note, verify internal temperature reaches 165°F (74°C) before serving.
Storage
Refrigerate leftover casserole within 2 hours of serving. Store in airtight container for maximum 3 days. Reheat to 75°C (165°F) before consuming leftovers.
Cross Contamination
Use separate utensils for handling raw tuna and other ingredients. Clean all prep surfaces and tools after working with fish to prevent allergen transfer.
High Risk Population
This dish contains fish and dairy - exercise extra caution when serving to pregnant individuals, young children, elderly, or immunocompromised persons. Ensure all ingredients are fully cooked.
Allergen Warning
Clearly label this dish as containing fish, eggs, milk, and gluten when serving to guests. Verify all packaged ingredients (mayonnaise, chips, breadcrumbs) for allergen statements.
Handling
Cool casserole to room temperature within 1 hour before refrigerating. Do not leave at room temperature for more than 2 hours total including serving time.
Shelf Life
Prepare fresh when possible. Casseroles with dairy and fish components have shorter shelf life than vegetable-only dishes. Discard after 3 days refrigerated.
Pro Tips
Technique
When making the cheese sauce, keep your heat at medium-low and patient-whip it. Rushing the cheddar in over high heat is how you get that grainy, broken mess nobody wants. We're going for silky here, baby.
Flavor Boost
Don't skip the hot sauce drizzle at the end — that smoke and acid cuts right through the richness and makes people keep coming back for another forkful. It's the boss move that ties everything together.
Substitution
No potato chips? Crushed tortilla chips or even Panko breadcrumbs tossed with melted butter work in a pinch, but honestly? The chips are the soul of this dish. Don't do it dirty.
Equipment
Use a proper baking dish here, not a sheet pan. We need those edges to bubble and caramelize while the chips toast on top — that's where the magic lives.
From the chef
I created this dish because I refuse to let 'convenience' be a four-letter word. See, I spent years in places where we treated canned tuna like it was beneath us, but that fish has been feeding people right since the Depression — it just needed some cheddar to flex and potato chips to get crispy in the oven. This Trash Mac is what happens when you take corner-shop ingredients seriously: a proper cheese sauce made from scratch, balanced seasoning, and that smoke-and-acid finish that makes people go quiet and just eat. It's the dish I wish someone had handed me at 2am after a long shift — soul food that doesn't apologize for being delicious.
