The Complete Guide to Cooking Legumes from Scratch
Canned beans are fine. Dried beans cooked from scratch are transcendent. A practical guide to every legume worth cooking and exactly how to cook it.
Dried legumes are the most underused ingredient in most kitchens. They are extraordinarily cheap, shelf-stable for years, nutritionally dense (protein, fibre, iron, zinc, folate), and — when cooked properly — genuinely delicious in a way that canned versions approximate but never fully achieve. The primary barrier is time, but that time is mostly passive: the legumes are soaking while you sleep, cooking while you work.
The Soaking Question
Most legumes benefit from soaking, which reduces cooking time by 30–50% and improves digestibility by beginning to break down complex sugars that cause gas. Overnight soaking in cold water, drained and rinsed, is the standard. Quick soaking (boil briefly, leave to sit for one hour, drain) works nearly as well.
Exceptions: red lentils and split peas need no soaking. French lentils (Puy) are better with a brief soak but tolerable without.
Legume by Legume
Chickpeas: The most versatile legume. Soak overnight, cook 1–1.5 hours. Keep in their cooking liquid. They improve over two to three days in the fridge, making them excellent for batch cooking. Use for hummus, curries, salads, roasting.
Black beans: Don't need as long as chickpeas — about 45–60 minutes after an overnight soak. The cooking liquid turns a dramatic dark purple and makes an excellent soup base. Great for tacos, grain bowls, Cuban-style preparations.
Cannellini: The creamiest white bean. Absorbs flavours beautifully. Core ingredient in Italian bean soups, pasta e fagioli, and anything that wants a mild, velvety protein element. Cook 45–60 minutes.
Puy lentils: The aristocrat of lentils. Hold their shape when cooked, have a distinctive peppery flavour. 25–30 minutes, no soaking required. Excellent in salads at room temperature with vinaigrette.
Red lentils: Dissolve when cooked, making them ideal for soups, dahls, and purées. 15–20 minutes. Never soak. The workhorse of quick weeknight cooking.
The Flavour Principle
Salt legumes at the end of cooking (salting too early can toughen the skin). Add aromatics to the cooking water: a bay leaf, a garlic clove, a strip of kombu (which also improves digestibility). The aromatics won't be dramatic, but they add a quiet foundation.
The biggest upgrade: finish cooked legumes in olive oil with garlic and fresh herbs before using. This step — five minutes — transforms them from a background protein to the main event.
Legumes are not a compromise for avoiding meat. They are one of the great ingredients of world cuisine, requiring only the patience to cook them properly.
