Make Once, Eat Twice: Air Fryer Sweet Potatoes (Plus a Cozy Soup)
This Air Fryer Sweet Potato Soup is silky, comforting, and surprisingly light — made with just sweet potato, onion, and ginger. No stovetop cooking or frying required — simply heat it up when you’re ready to enjoy a hot, nourishing bowl. It’s delicious served hot or cold, perfect for flasks (as shown in the image below), meal prep, or quick weeknight dinners. The convenience is almost shocking — and it doesn’t hurt that it’s a great way to sneak in more wholesome ingredients and support your healthy eating habits.
Reduce Food Waste
This soup is a great way to use up leftovers! Roasted sweet potatoes from another meal? Toss them in. That half onion or sad-looking carrot in the fridge? Blend it in. Even your last bit of stock or broth works perfectly here. It’s a flexible, forgiving recipe that turns what you already have into something delicious.
Why You’ll Love This Recipe
This is your two-in-one sweet potato recipe: make crisp, caramelized air fryer sweet potatoes one day, and use the leftovers to create a creamy, cozy soup the next. It’s practical, waste-free cooking that tastes fantastic.
Ingredients You Will Need
- Sweet potatoes (2 medium) – roasted with skins on for added flavor, texture, and nutrition
- Olive oil – adds richness and helps the sweet potatoes crisp in the air fryer
- Salt + black pepper – basic seasoning to bring out the natural sweetness
- Spice blend – a touch of heat and depth; try smoked paprika, cumin, or chili powder
This short, simple ingredient list is all you need to air fry the sweet potatoes and build a deeply flavorful soup base — no extra pots or pans required.
The ingredient list above is all you need to air fry the sweet potatoes. In my case, there were leftovers — so the next day, I used them for a soup! That’s how this became a bit of a double-duty recipe. For the soup version, you can then add extra ingredients like onion, ginger, stock or almond milk — whatever you have on hand. I didn’t know I’d be turning this into a soup or I would’ve added fresh garlic to the air fryer with the sweet potatoes, so go ahead and experiment. It’s incredibly forgiving and full of possibilities.
🥣 Optional Ingredients for the Soup
Once your sweet potatoes are roasted, here are a few simple add-ins to blend into a silky, flavorful soup:
- Onion or shallot – sautéed or raw for extra depth
- Fresh garlic or ginger – adds warmth and a little bite
- Vegetable stock or water – to thin and blend
- Almond milk or coconut milk – for a creamy, dairy-free finish
- A spoon of red pepper sauce or harissa – for heat and brightness
- Seasoning – taste and adjust with salt, pepper, and your favorite spices
Feel free to get creative — this recipe is more of a template than a rulebook.
How to Make Air Fryer Sweet Potato Soup
Step 1: Roast the Sweet Potatoes
Cut the sweet potatoes into cubes or thick rounds (keep the skins on for extra flavor and nutrition).
Toss with a little olive oil, salt, and pepper.
Air fry at 200°C / 400°F for 25 minutes, shaking halfway through for even browning.
Step 2: Store Any Leftovers
Use the roasted sweet potatoes right away or let them cool completely.
Store in an airtight container in the fridge for up to 2–3 days.
Step 3: Blend the Soup
Add the leftover sweet potatoes to a blender along with:
• Almond milk (or your choice of milk)
• Thinly sliced red onion
• Fresh ginger
• Salt, pepper, and your favorite seasonings
Blend until completely smooth and silky. Add more almond milk or a splash of warm water to adjust the consistency.
Taste and finish with a squeeze of lemon juice or a spoonful of quick pink sauce, if you like.
Serve warm or cold.

Recipe Notes
💡 Recipe Notes
- Don’t skip the skins – Once roasted, sweet potato skins add both flavor and nutrition.
- Meal prep tip – Roast extra sweet potatoes in one go and refrigerate for quick meals during the week.
- No air fryer? – Roast in a conventional oven at 200°C / 400°F for 30–40 minutes, turning once.
- Blender tip – A high-speed blender gives the smoothest, silkiest soup texture.
Side Note:
If you’re using sweet potatoes that have been stored in the fridge for a day or two, you’ll notice the skins often peel off easily. I usually discard them before blending for a smooth soup — but they’re still delicious as a snack on their own!
Variations
This soup is flexible and easy to customize:
- Add a pinch of cumin or a spoon of curry powder for a warming spice twist.
- Roast carrots or parsnips alongside the sweet potato for extra depth and sweetness.
- Make it more filling by blending in a scoop of cooked quinoa or white beans for added protein.
Serving Ideas
Enjoy this Air Fryer Sweet Potato Soup:
- With a slice of warm toast Garlic, Cheese and Herb Toast or my easy crusty bread for dipping
- As a cozy starter before dinner
