It smells of red onion melting gently in the pan, with that little sweet aroma that immediately makes you want to build the burger. Here, no need for a complicated patty: lentils, a few vegetables, melted Reblochon, and a well-toasted bun. It’s the kind of everyday vegetarian burger that really fills you up, without requiring an entire evening in the kitchen.

Ingredients :
- Cooked green lentils — They form the base of the patty and provide a firm, almost rustic texture that holds well in the burger. Choose them well-drained, otherwise the mixture becomes soft; brown lentils can work if not overcooked.
- Carrot — It adds natural sweetness and a bit of color to the patty, especially when cut into small dice. Use a firm carrot and avoid large chunks, as they stay crunchy while the rest of the patty is tender.
- White mushrooms — They add moisture and a deeper flavor, with a slightly woody aroma when cooked. Brown mushrooms work very well too, often with more character.
- Rolled oats — They absorb excess moisture and help the patty hold together without eggs. If you don’t have any, use a little breadcrumbs, but add them gradually to avoid making the mixture too compact.
