Ingredients for 2 servings

2 servings

Check off ingredients as you go.

No regulated allergens in the ingredients as listed. Check the labels on packaged ingredients:

  • polenta. Maize is not a gluten cereal, but some polenta is milled alongside wheat; check the packet if you avoid gluten.
  • vegetable stock. Vegetable stock often contains celery, and some contain milk or gluten; check the label, especially if you need it vegan.

Cooking steps

  1. Bring the water to the boil, pour in the polenta in a thin stream, whisking, and cook over low heat for 5 to 8 minutes, stirring, until thick.

  2. Brush a small baking dish with a little of the oil, spread the polenta in it and leave it to firm up while you make the topping.

  3. Heat the oven to 190°C / 375°F (170°C fan). Warm the rest of the oil in a frying pan over medium-high heat and cook the mushrooms for 6 to 8 minutes, until browned.

  4. Add the beans, stock and thyme and simmer for 5 minutes, until saucy but not dry. Spoon over the polenta.

  5. Bake for 20 to 25 minutes, until hot all the way through and bubbling at the edges.

    Cooked when: 74°C / 165°F, steaming hot throughout. A food thermometer is the reliable way to tell.

The useful detail

Keep the bean topping spoonable rather than dry. Polenta absorbs liquid from above as it bakes, so a topping that looks slightly wet in the pan is right by the time it reaches the table.

Make it work for you

One serving is Half the dish. You can switch to a smaller portion in the ingredients above; it is three quarters of this, and it contains correspondingly less energy and protein. It is an option, not a goal.

  • Butter beans instead of cannellini

    Larger and softer. The figures use the same record.

    Per serving: about the same energy, about the same protein, about the same fat.

  • Chestnut mushrooms

    Deeper flavour and firmer texture. Nutrition is not recalculated.

  • Add a vegetarian hard cheese on top

    Scatter 20 g before baking, if you are not vegan. Nutrition is not recalculated.

    Allergens: Adds milk.

Estimated nutrition

Per standard serving, calculated from the ingredients above. Nutrition changes with substitutions, brands and how much oil stays in the pan.

A vegan bake that is naturally free of gluten if the polenta is milled apart from wheat. The beans carry the protein and the fibre.

Show calculation notes

Each ingredient’s weight is multiplied by its USDA FoodData Central values per 100 g. The whole recipe is added up and divided by 2. Raw weights are used for meat, fish and vegetables; beans and lentils are drained weights. All of the oil is counted as eaten. Added salt is not included; sodium from stock, bread, cheese and tinned food is.

Storage and reheating

In the fridge
Cool, cover and refrigerate within 2 hours of cooking. Eat within 3 to 4 days. It sets firm and can be sliced and fried the next day.
In the freezer
Freezing keeps food safe indefinitely; the texture is best if it is eaten sooner rather than later.
Reheating
Reheat until it reaches 74°C / 165°F, steaming hot throughout.

Checked against US Food and Drug Administration, Refrigerator and Freezer Storage Chart, USDA Food Safety and Inspection Service, Leftovers and Food Safety, FoodSafety.gov, Safe Minimum Internal Temperatures and FoodSafety.gov, Cold Food Storage Chart. UK guidance from the Food Standards Agency is shorter, at two days for most leftovers.
