In a mixing bowl, combine the cubed potatoes with the oil and seasonings. Add them to your air fryer and cook at 200°C (392°F) for 25 minutes, shaking halfway through. To roast the potatoes, spread them evenly on a large baking sheet and bake at 220 °C (428°F) for 30-35 minutes.
Meanwhile, make the black beans. Heat the oil in an oven-proof skillet and add the diced onion and garlic. Sauté for 4-5 minutes, stirring occasionally.
1 tablespoon olive oil, 1 white onion, 2 garlic cloves
Add the tomato puree, chipotle paste, and seasonings, and stir these into the onions for another minute.
Add the black beans, water, and diced roasted red pepper to the pan. Simmer for 10- 15 minutes, using your wooden spoon to mash about ⅓ of the black beans until the mixture is thick and creamy.
1 roasted red pepper, 2 400g tinned black beans, 200 ml water
Add the crispy cubed potatoes on top of the black beans. Then, scatter the grated cheese and jalapeños over the top.
100 g grated cheddar and mozzarella cheese blend, 6-7 jarred jalapeno slices
Pop the skillet under the grill for 5 minutes or until the cheese is melted and golden and bubbly.
Top with the cilantro and a spoonful of yogurt or sour cream when serving.
1 tablespoon yogurt or sour cream, 10 g diced fresh cilantro
If you don't have a cast-iron skillet or oven-proof pan, transfer the black beans to an oven-proof dish before adding the potatoes on top.
Potatoes: Make sure you cut the potatoes into small enough cubes (1- 2 cm) so they get evenly crispy for the topping. Air fry 25 min at 200°C or oven roast 30-35 min at 220°C while you make the black bean filling.
Beans: Mash about ⅓ of the black beans with a wooden spoon for a thick, saucy texture - you don’t want the beans to be too watery, or the potatoes will sink into the sauce.
Storage: Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven for 20 minutes or until piping hot - you could microwave it, but the beans won’t be as crispy. The bean mixture freezes well (3 months) - but I would recommend freezing without the potatoes/cheese topping for best results.
