the finished dish—this doesn’t count toward the core 4 ingredients, but it does brighten the plate. You can also swap yellow onion for sweet onion if you like a more caramelized, candy-like flavor. Leftovers reheat best in a covered skillet over low heat with a splash of water or broth to keep the pierogies soft and the sauce silky.
My neighbor Karen brought this over and we scraped the bowl clean. Comfort food at its finest. Just 4 ingredients.
