Crispy Chilli Sizzle Potatoes with Gooey Garlic Aioli

Why You’ll Love This Recipe

I love how this recipe transforms humble potatoes into something truly addictive. The spicy chilli sizzle oil gives them a bold, fragrant heat while the roasted garlic aioli adds a creamy richness that ties everything together. Whether I’m serving this as a weekend snack, a party appetizer, or a hearty side dish, it always disappears fast. The air fryer option also makes it quick and less oily, perfect for busy weeknights.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• 4 large cloves of garlic

• 800g baby potatoes

• 1/3 cup French-style mayonnaise

• 4 spring onions

• 1 heaped tablespoon chilli flakes

• 1/4 cup oil

• Oil, salt, and pepper as needed

Directions

1. Roast the Garlic

I wrap the garlic cloves in foil, drizzle with oil, sprinkle with salt, and seal them up. Then I roast them alongside the potatoes so they turn soft, caramelized, and full of flavor.

2. Prep and Parboil the Potatoes

After washing and halving the baby potatoes, I boil them in salted water until just fork-tender—soft inside but still holding their shape, which usually takes 6–10 minutes depending on size.

3. Roast or Air Fry

I drain the potatoes and toss them with a little oil and salt. Then I spread them on a baking tray (or into the air fryer basket) along with the foil-wrapped garlic. In the oven, I roast them at 200°C for 20–30 minutes until golden. In the air fryer, it takes about 10–14 minutes at 200°C, shaking halfway through for even crispiness.

4. Make the Chilli Sizzle Oil

While the potatoes are cooking, I finely slice the spring onions and place them in a bowl with the chilli flakes. Then I heat oil until it’s just about smoking and pour it over the mixture. The sizzling oil lightly fries the onions and chilli flakes, creating a super fragrant topping.

5. Make the Gooey Garlic Aioli

Once the garlic is roasted, I squeeze the soft cloves from their skins and mash them into a smooth puree. I stir this into the mayonnaise and season with salt and pepper. The result is a luscious, garlicky aioli that’s creamy and savory.

6. Assemble and Serve

I smear the garlic aioli over a serving platter, pile the crispy potatoes on top, and spoon over the spicy spring onion sizzle oil. This dish is best served hot and fresh—crispy, creamy, and full of flavor.

Variations

• I swap baby potatoes for fingerlings or Yukon golds when I want something a little heartier.

• For a smoky twist, I add a pinch of smoked paprika to the sizzle oil.

• Sometimes I use Greek yogurt instead of mayo for a lighter, tangier aioli.

• If I want more heat, I throw in a few fresh chopped chillies with the spring onions.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 3 days. To reheat, I spread the potatoes on a tray and bake at 180°C for about 10 minutes until they crisp up again. I always store the aioli separately and add it fresh before serving.

FAQs

What kind of potatoes work best?

I like using baby potatoes for their size and texture, but Yukon Gold or red potatoes work just as well. I keep the skins on for extra crispiness.

Can I make this without an air fryer?

Yes! I often roast them in the oven at 200°C for 20–30 minutes. Just be sure to turn them halfway through to get that golden finish.

Is the garlic aioli strong?

Not at all. Roasting the garlic softens and sweetens it, so the aioli ends up creamy and mellow with a gentle garlic flavor that’s super smooth.

How spicy is the chilli sizzle oil?

It’s got a good kick, but I adjust the chilli flakes to taste. If I want it milder, I use half the amount or mix in some sweet paprika.

Can I make this ahead of time?

Yes, I roast the garlic and parboil the potatoes ahead of time. Then, just before serving, I roast or air fry the potatoes and assemble the dish fresh.

Crispy Chilli Sizzle Potatoes with Gooey Garlic Aioli is one of those dishes that hits all the right notes—crispy, spicy, creamy, and comforting.
