French onion soup is not just a forever favorite of mine, it’s — along with the other recipes I updated this month — what I consider a core recipe in my arsenal because it aligns with so much that I think is important in cooking. It’s totally budget-friendly (and downright cheap) to make. It’s made from buy-anywhere ingredients and very few of them — 99% of the flavor comes from just onions, cooked very slowly, transformed by a technique you need no advanced cooking skills to master. And it has a depth of flavor that is unparalleled in almost anything else I know how to make.
