Creamy Celeriac, Roast Garlic and Mushroom Carbonara
A lovely, deliciously creamy and tasty mushroom carbonara with roast celeriac and garlic – it’s super smooth with no dairy, oil or nuts but still dreamy.

I love this deliciously creamy, tasty sauce made with roast celeriac and garlic – super smooth with no dairy, oil or nuts but still encases the spaghetti beautifully.
I reserved some of the roast celeriac to top the spaghetti along with the roast onions and sautéed mushrooms.
It’s absolutely packed with flavour and would make a wonderful Valentine’s or celebration meal.
I hope you enjoy this, much love. Niki xxx

Delicious. I cooked the mushrooms with garlic salt and smoked paprika, and added red pepper and peas . Definitely will be making again.
So happy you like Mel!

I really loved the idea of this dish and was excited to try it, but I was honestly disappointed. I didn’t think it tasted very well and was somewhat bland.
OMG!! This recipe is soooo good! The sauce I could actually quite happily eat with a spoon . Awesome Nikki
Thank you for this creative use for celery root which I had in my organic produce bag this week. The sauce made a large amount, and was very thick (I used unsweetened oat milk, which is what I had), so I thinned it quite a bit with the pasta water. I’m going to try and freeze the leftover sauce, I think it would be a nice addition to thicken a soup. Any other suggestions? Overall a very rich, tasty and satisfying dish.
