Ingredients

Cook the macaroni just shy of done, and add the chips at the end. The pasta keeps cooking in the oven, so drain it a minute early or it goes mushy. Scatter the crushed chips on only for the bake so they stay crisp instead of turning to paste.

Easier, if you like

  • Pre-shredded cheese (about 1 cup) saves grating.
  • One bowl: stir everything together with the just-cooked macaroni, top, and bake — no separate sauce step needed if you're in a hurry.

Method

    Cook's notes

    Cheap, fast, filling. This is the classic stretch-the-pantry supper — a couple of cans and a box of pasta feed a table.

    Don't fully cook the macaroni before it bakes; just-shy-of-tender keeps it from going soft.

    Stretch it further with a handful of frozen peas or some chopped celery stirred in.

    No potato chips? Crushed crackers or buttered bread crumbs give the same crisp top.

    Easy to make gluten-free

    Gluten-free: use gluten-free pasta and a gluten-free condensed soup, and top with crushed corn chips or GF crackers.

    No pimiento: a little chopped roasted red pepper, or just leave it out.
