For picky eaters, you can chop the cabbage more finely so it blends in with the noodles and is less noticeable in big strands. If your family likes a little extra richness, drizzle another 2–3 tablespoons of melted butter over the top right after baking. To stretch the recipe for a crowd, you can add up to 4 more ounces of noodles and increase the butter and salt slightly so everything still tastes well-seasoned. For those who enjoy a bit of browned flavor, leave the casserole uncovered for the full bake and stir once halfway through to encourage more caramelized cabbage throughout. You can also add a light sprinkle of black pepper or garlic powder before baking without really changing the spirit of the four-ingredient recipe. Leftovers reheat nicely in a skillet with a small pat of butter—just warm gently over medium heat until the noodles and cabbage crisp up around the edges again, which makes for a cozy next-day lunch.
