Quick Roast Celeriac with Lemon (Oven or Air Fryer)
This roast celeriac recipe is quick and easy and absolutely delicious! Roast chunks of celeriac in the oven or quickly in the air fryer a low carb, keto-friendly vegetable side dish.
Pre-heat the oven to 190°C and line a baking tray with baking paper OR set the air fryer to 180°C.
Cut the root end off the celeriac then lay the flat end on the chopping board and, using a sharp knife, carefully slice off the skin in downward strips. Once peeled, cut the celeriac into slices and then again into chunks.
1 celeriac
Put the celeriac pieces into a bowl and drizzle with the olive oil, some salt and pepper and the juice of half the lemon. Mix together well.
1 tablespoon olive oil, 1 lemon, salt and pepper
For oven-roasting: lay the celeriac pieces on the lined baking tray and place in the oven. Roast for 20-25 minutes, turning the celeriac pieces over half way through cooking.
For air-frying: lay the celeriac pieces in the air fryer basket, trying to keep them in a single layer. Air fry for 15-20 minutes, shaking the basket half way through cooking.
The cooking time depends on the size of the celeriac pieces. Check whether the celeriac is cooked through by piercing with a knife. It should feel soft and easy to slide the knife in. If there is resistance, just pop it back in the oven or air fryer for a few more minutes until soft. If it starts to brown too much, turn the oven temperature down a little.
Serve with another generous squeeze of lemon and some fresh herbs scattered over the top.
handful of fresh herbs
Notes
The cooking time will depend on the size of the celeriac pieces. The larger they are, the longer they will take to cook through.
Serve roast celeriac wedges as a substitute for roast potatoes or serve celeriac chips with vegan mayonnaise mixed with spice sriracha sauce.
