Air-fryer sweet potato black bean tacos

Crisp air-fried sweet potato and black beans fill warm tacos with avocado.

This recipe makes 4 servings and takes about 20 minutes to prepare plus 20 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 air fryer, mixing bowl, small saucepan, fork. 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, 1.5 cm diced: 600 g (1 lb 5 oz); red onion, wedges: 150 g (5 oz); olive oil: 15 ml (1 tbsp); ground cumin: 4 g (2 tsp); smoked paprika: 2 g (1 tsp); black beans, drained and rinsed: 480 g (2 cans); corn tortillas: 320 g (11 oz); avocado, sliced: 300 g (10½ oz); lime juice: 30 ml (2 tbsp). Gather the ingredients before heating the pan so the aromatics do not burn while a measurement is being found.

• sweet potato, 1.5 cm diced — 600 g / 1 lb 5 oz
• red onion, wedges — 150 g / 5 oz
• olive oil — 15 ml / 1 tbsp
• ground cumin — 4 g / 2 tsp
• smoked paprika — 2 g / 1 tsp
• black beans, drained and rinsed — 480 g / 2 cans
• corn tortillas — 320 g / 11 oz
• avocado, sliced — 300 g / 10½ oz
• lime juice — 30 ml / 2 tbsp

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

Toss sweet potato and red onion with olive oil, ground cumin and smoked paprika.

Step 2

Air-fry at 200°C/400°F for 16 to 18 minutes, shaking twice, until the sweet potato is browned and tender.

Step 3

Warm black beans in a small saucepan until steaming. Warm corn tortillas in a dry pan or microwave until flexible.

Step 4

Fill corn tortillas with sweet potato, red onion, black beans and avocado. Drizzle with lime juice and serve immediately.

Cooking and safety check

Heat the black beans until steaming and cook sweet potato until tender at its centre. 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 flour tortillas instead of corn tortillas; flour tortillas contain gluten. Use pinto beans for black beans. Use roasted squash for sweet potato.

Allergen notes

No major allergen is inherent in the core ingredients listed, but check every packaged ingredient and seasoning blend 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.

• Cut sweet potato no larger than 1.5 cm for quick cooking.
• Shake the basket to expose new surfaces to heat.
• Add avocado only at serving so it does not brown.

Leftovers and storage

Refrigerate the sweet potato, onion and beans for up to three days. Reheat them until steaming and assemble with fresh avocado and tortillas.
