Making a pressure cooker cassoulet is not necessarily a bad idea, but it might not result in the same traditional flavors and textures as the slow-cooked, oven-baked version. Cassoulet is a classic French dish that involves cooking various meats, beans, and herbs in a deep casserole dish for an extended period, allowing the flavors to meld and develop.
When using a pressure cooker, the cooking time is significantly reduced, which can impact the final taste and texture of the dish. The beans might not become as creamy, and the flavors might not have the same depth as when cooked slowly.
However, if you're short on time and still want to enjoy a cassoulet-inspired meal, a pressure cooker can be a convenient and efficient way to prepare it. Just keep in mind that the result may differ from the traditional version. If you have the time and prefer a more authentic cassoulet, consider trying the slow-cooked method in the oven for the best results.
