These air fryer smashed potatoes are golden and crisp around the edges, then topped with smoky taco-spiced beef, red kidney beans, fresh tomatoes and a cooling lime yoghurt sauce.
Inspired by loaded fries and crispy smashed potatoes, this homemade version uses affordable supermarket ingredients to create a colourful, satisfying family meal. Keeping the potato skins on adds texture, while the beef and beans make the topping more substantial.

How to Make Air Fryer Loaded Taco Smashed Potatoes
1. Boil the potatoes
Place the baby potatoes in a saucepan and cover with cold water.
Bring to the boil, then simmer for approximately 15–20 minutes, until tender enough to pierce easily with a fork.
Drain thoroughly and leave to steam-dry for 3–5 minutes. This helps the potatoes become crisp in the air fryer.
2. Smash and season
Place the potatoes on a clean board or tray. Gently press each one with the base of a glass or potato masher until flattened to approximately 1–1.5cm thick.
Take care not to break them completely apart.
Brush or drizzle with olive oil, then sprinkle over the smoked paprika, garlic granules, black pepper and salt, if using.
3. Air fry the potatoes
Preheat the air fryer to 200°C, if required by your model.
Arrange the potatoes in a single layer, leaving a little space between them. Cook in batches if necessary.
Air fry for 18–25 minutes, checking after 15 minutes, until the edges are golden and crisp. Turn carefully if needed, although delicate potatoes may be best left undisturbed until the underside firms up.
4. Prepare the taco topping
While the potatoes cook, place a large non-stick frying pan over a medium heat.
Add the lean beef mince and onion. Cook for approximately 5–6 minutes, breaking up the mince with a wooden spoon, until the beef begins to brown.
If necessary, drain away any excess fat.
5. Add the vegetables and spices
Stir in the red pepper and garlic. Cook for another 2 minutes.
Add the cumin, smoked paprika, coriander, oregano, chilli powder and black pepper. Stir for 30 seconds to release the aromas.
6. Add the beans and tomatoes
Stir in the drained kidney beans and chopped tomatoes.
Simmer gently for 5–7 minutes, adding a little water if the mixture becomes too thick. The beef should be completely cooked, with no pink remaining, and the topping should be hot throughout.
Taste and adjust the seasoning.
7. Make the lime yoghurt sauce
Mix the Greek yoghurt, lime juice, garlic granules and black pepper in a small bowl.
Add a little cold water until the sauce is thin enough to drizzle. Keep refrigerated until serving.
8. Assemble the loaded potatoes
Divide the crispy smashed potatoes between four plates or shallow bowls.
Spoon the hot taco beef and bean mixture over the top. Sprinkle with the grated Cheddar, allowing it to soften against the warm topping.
Finish with diced tomato, shredded lettuce, spring onions and a drizzle of lime yoghurt sauce.
Serve immediately with lime wedges, if using.
Tips for Crispy Air Fryer Smashed Potatoes
Choose similar-sized potatoes. They will boil and crisp more evenly.
Steam-dry after boiling. Removing surface moisture helps produce golden edges.
Do not flatten them too thinly. Aim for approximately 1–1.5cm so they remain fluffy inside.
Avoid overcrowding. Cook in batches to allow hot air to circulate.
Add toppings just before serving. This helps the potatoes retain their crisp texture.
Keep the taco topping fairly thick. A watery sauce can quickly soften the potatoes.
Easy Budget-Friendly Variations
Chicken Taco Potatoes
Replace the beef with lean chicken mince. Cook it thoroughly before adding the beans and tomatoes.
Vegetarian Loaded Potatoes
Leave out the beef and use an additional tin of drained kidney beans or a mixture of kidney beans and black beans. Add extra vegetables if preferred.
Mild Family-Friendly Version
Leave out the chilli powder and serve hot sauce separately so everyone can adjust their portion.
Sweet Potato Variation
Use small sweet potatoes instead of baby potatoes. Their texture and cooking time will differ, so check them regularly.
Use Leftover Vegetables
Finely diced courgette, mushrooms or carrots can be added to the taco topping to make use of ingredients already in your fridge.
Can You Make Loaded Taco Smashed Potatoes Ahead?
Yes. The taco beef and bean topping can be prepared in advance and refrigerated once cooled.
You can also boil the potatoes ahead of time. For the best texture, smash and air fry them shortly before serving.
Keep the salad and yoghurt sauce separate until you assemble the dish.
How to Store and Reheat
Allow leftovers to cool promptly, then store the potatoes and taco topping in separate airtight containers in the fridge at 5°C or below for up to 2 days.
Reheat the potatoes in the air fryer at 180°C for approximately 5–8 minutes, until piping hot and crisp again.
Reheat the beef and bean topping separately until piping hot throughout. Reheat leftovers only once.
Keep the yoghurt sauce refrigerated and add fresh lettuce and tomato after reheating.
The cooked beef and bean topping can be frozen separately. Defrost thoroughly in the fridge before reheating.
Frequently Asked Questions
Do I need to boil potatoes before air frying them?
For this recipe, yes. Boiling softens the centres so the potatoes can be flattened without breaking apart. Air frying then creates the crisp edges.
Can I use ordinary potatoes instead of baby potatoes?
Yes. Cut larger potatoes into evenly sized pieces before boiling, then smash them once tender.
How do I keep smashed potatoes crispy?
Drain and steam-dry them thoroughly, use a small amount of oil and avoid overcrowding the air fryer basket. Add the toppings immediately before serving.
Can I make the taco topping without beef?
Yes. Try a mixture of kidney beans, black beans and finely chopped vegetables for a meat-free version.
Can I use a different cheese?
Yes. A little grated reduced-fat Cheddar or mozzarella can replace mature Cheddar.
