Ingredients List


Air Fryer Tempura Broccolini and Sweet Potato

Broccolini – trimmed the ends of but keep whole if you like. Feel free to use normal broccoli if you prefer.

Red Sweet Potato – cut into discs or sticks.  Slice into regular even shapes to make cooking time even.

Self Raising flour – the tempura batter for this recipe uses Self Raising Flour though normal recipes often use

Salt – seasoning as always.

Sparkling Water – chilled is best for this batter recipe.

Sweet Chili Sauce – optional but gives it just a little bit of colour and taste plus it’s not hot at all.

Egg – to keep it all together.  We love to use free range.

Panko Bread Crumbs – these make the crunchiest exterior ever and found in most supermarkets. Panko (we use the Obento brand)  are dryer and flakier and don’t absorb as much oil.

Olive Oil – this is mixed in with the panko breadcrumbs so when your veggies are cooking they’ll bet a nice golden coloring.


What Is Tempura Batter?

Tempura batter is a light, crispy coating made from wheat flour, cornstarch, baking powder and ice-cold water. It is commonly used to coat seafood and vegetables before deep-frying. Even though this recipe doesn’t use the cornstarch or baking power the self raising flour works well.

Tempura batter is always a favourite dish in Japanese menus, plus it’s one we order every time we go.


Step by Step Instructions –

Just a quick visual but the full instructions are in the recipe details below.

Step 2. Set yourself up like a production line.

Have everything ready to go.  Your chopped veggies, bowl of batter, panko crumbs and a tray with a wire rack to sit the veggies on after dipping. It’s probably easier to do one lot of veggies first and cook them rather than dipping the whole amount and letting them sit for too long.
