When winter brings its bounty of root vegetables, Jerusalem artichokes (also known as topinambur) are often overlooked gems. This creamy, savory flan transforms these humble tubers into an elegant dish that perfectly balances earthy flavors with rich cheese and sweet chestnuts.
What makes Jerusalem artichokes special isn’t just their delicate, nutty flavor – they’re packed with nutritional benefits too! Rich in iron, potassium, and prebiotic fiber (inulin), they support gut health and boost your immune system. Combined with protein-rich eggs and calcium-packed cheese, this flan becomes a nutritious winter warmer that’s as healthy as it is delicious.
What I love about this recipe is how it elevates simple ingredients into something special. The natural sweetness of Jerusalem artichokes pairs beautifully with the salty parmigiano while ricotta adds a silky smoothness. Topped with crunchy chestnuts and fresh thyme, it’s a perfect starter or light lunch for 2x that celebrates winter’s finest ingredients.
This versatile flan welcomes creative substitutions while maintaining its elegant character. Fresh rosemary can replace thyme for a more robust herb flavor. No chestnuts? Try toasted walnuts or hazelnuts for crunch, or even some pan-fried black olives for a Mediterranean twist. The key is maintaining the balance between the creamy flan and a crunchy topping that adds texture and visual appeal.
