Ingredients

Why metric?

Metric avoids regional spoon ambiguity. US uses 5 mL tsp, 15 mL tbsp and 240 mL cup. Small masses stay in grams unless a verified recipe conversion exists. More on measurements

  • 500 g mushrooms, thickly sliced
  • 200 g canned cannellini beans, drained and rinsed
  • 1 medium brown onion, finely chopped (150 g)
  • 3 garlic cloves, finely chopped (15 g)
  • 50 ml extra-virgin olive oil (45 g)
  • 2 g dried thyme
  • 200 g canned no-added-salt tomatoes
  • 280 g fine quick-cooking polenta (dry)
  • 660 ml milk (680 g)
  • 800 ml water (800 g)
  • 65 g parmesan, finely grated
  • 50 g unsalted butter
  • 10 g flat-leaf parsley, chopped
  • Ground black pepper, to taste

Method

  1. Heat half the oil in a wide pan over high heat and add the mushrooms in one layer. Leave them 2 minutes, then stir and cook 6-8 minutes, until the water they throw out has boiled away entirely and they squeak and brown. Tip them into a bowl.
  2. Turn the heat down, add the rest of the oil and cook the onion for 8 minutes, until soft and translucent. Add the garlic and thyme and cook 30 seconds.
  3. Return the mushrooms with the tomatoes and beans, crushing the tomatoes against the side of the pan. Simmer 12-15 minutes, until the sauce has thickened enough to hold a trough behind the spoon.
  4. Meanwhile bring the milk and water to a bare simmer in a heavy saucepan. Rain the polenta in with one hand while whisking hard with the other; tipped in at once it seizes into lumps that never come out.
  5. Cook 8-10 minutes on the lowest heat, stirring often with a wooden spoon and reaching into the corners. It thickens fast and spits, so keep the heat low. It is ready when it no longer tastes gritty and falls off the spoon in a soft ribbon.
  6. Beat in all of the butter and parmesan. No salt is weighed into this dish anywhere: the parmesan seasons the polenta on its own, and the beans are rinsed hard for the same reason. Loosen with hot milk until it spreads slowly across a plate rather than sitting in a mound.
  7. Spoon the polenta into four bowls, ladle the stew into the middle and finish with parsley and pepper.

Safety and storage

Keeps

Cool and cover within two hours of cooking; split large amounts into shallow containers so they chill quickly. Reheat until steaming hot, at least 60°C.
