Sweet potato, black bean and kale bake

This layered bake pairs tender sweet potato and black beans with kale and cheddar.

This recipe makes 4 servings and takes about 20 minutes to prepare plus 40 minutes to cook. Metric and imperial quantities are alternate measurements, so use one system rather than adding both. If you change the yield, keep the pan size and thickness of the food in mind: a crowded pan steams food and a deep baking dish can extend the cooking time.

Equipment

Set out 20 by 30 cm baking dish, large frying pan, foil, grater. A wide pan gives moisture somewhere to evaporate; for an oven dish, leave space between pieces so heat can circulate. Use separate board and knife surfaces for raw protein and foods that will be eaten without further cooking.

Ingredients

You will need: sweet potato, thinly sliced: 700 g (1 lb 9 oz); black beans, drained and rinsed: 480 g (2 cans); kale, shredded: 200 g (7 oz); onion, sliced: 150 g (5 oz); olive oil: 15 ml (1 tbsp); ground cumin: 4 g (2 tsp); chopped tomatoes: 400 g (14 oz); mature cheddar, grated: 200 g (7 oz). Gather the ingredients before heating the pan so the aromatics do not burn while a measurement is being found.

• sweet potato, thinly sliced — 700 g / 1 lb 9 oz
• black beans, drained and rinsed — 480 g / 2 cans
• kale, shredded — 200 g / 7 oz
• onion, sliced — 150 g / 5 oz
• olive oil — 15 ml / 1 tbsp
• ground cumin — 4 g / 2 tsp
• chopped tomatoes — 400 g / 14 oz
• mature cheddar, grated — 200 g / 7 oz

Method

Read the full method once, then prepare the ingredients in the order listed. Keep raw and ready-to-eat ingredients separate, and wash hands and equipment after raw-protein contact.

Step 1

Heat the oven to 200°C/400°F. Cook onion in olive oil for 5 minutes, then add kale and cook until wilted.

Step 2

Stir in ground cumin, chopped tomatoes and black beans; simmer for 5 minutes.

Step 3

Layer half the sweet potato in the baking dish, spread over the black bean mixture, then cover with remaining sweet potato. Cover tightly with foil and bake for 25 minutes.

Step 4

Remove foil, scatter with mature cheddar and bake for 12 to 15 minutes until the cheese is browned and sweet potato is tender when pierced.

Step 5

Rest for 5 minutes before serving.

Cooking and safety check

Bake until the centre is steaming hot and every sweet potato slice is tender. A time estimate and a browned surface do not prove that the centre is cooked. Use a suitable food thermometer where the ingredient or local guidance requires one, and follow the package or official instructions for the specific food.

Substitutions that respect the dish

A substitution should preserve the recipe’s job, not merely its colour. Use cavolo nero in place of kale. Use dairy-free grated cheese for a milk-free bake. Use pinto beans for black beans.

Allergen notes

This recipe contains or may contain milk. Check every packaged ingredient because formulations and cross-contact warnings vary.

Common mistakes and how to correct them

Use one troubleshooting change at a time. If the centre is undercooked, return it to the appropriate heat and check again rather than relying on the outside colour. If the pan is dry, add liquid gradually; if it is watery, reduce uncovered. Texture may also reflect crowded equipment, a different ingredient size, or a changed batch quantity.

• Slice sweet potato evenly so the top layer cooks through.
• Keep the foil sealed for the first bake to trap steam.
• If sweet potato is still firm, cover again and bake for 10 more minutes.

Leftovers and storage

Cool and refrigerate for up to three days. Reheat covered at 180°C/350°F until hot throughout.
