This was lovely, will definitely make again.

I made this without the bacon and served it with beef bourguignon. Perfect (and very greedy!)

Really delicious. I didn't have double cream so used whipping cream and a couple of spoons of mascarpone. Luckily I have a mandolin which made all the slicing a breeze. Served this with the steaks in red wine sauce and steamed kale and there were compliments all round!

Wow! This is DELICIOUS! Will be making this again & will add more celeriac next time. Don't hesitate - make this dish!!

Very nice. Added cheese on top for some extra calories.

Very nice. Easy to make and very tasty. Omitted the bacon and didn't miss it. Everyone went for seconds.

Wasn't really one of our favourite, had too much liquid and fat in it. Unfortunately it didn't worth the trouble.

Lovely lovely lovely! My first time with celeriac and I will be back! This dish is delicious. I adapted it slightly to use up what I had in (leftover whipping cream mixed with creme freche worked instead of double cream & wholegrain mustard instead of dijon). Didnt use the bacon and the dish didnt miss anything. Yummy

family enjoyed this, good way to get kids to eat more veg!

Would definitely make again, though perhaps 2 layers of potato to one of celeriac. Wasn't expecting such a bold flavour. Also needed a much bigger gratin dish as half my sauce ended up on the bottom of the oven!

I served this with the roasted lamb, so I omitted the bacon. It was absolutely delicious, the combination of potato, celeriac and rosemary - yummy! Will make it again very soon.

Food processor is a necessary advantage for this recipe unless your knife skills are good

Used half double cream and half lower fat creme fraiche and I don't think it impaired the flavour. Omitted the bacon and served alongside a veggie sausage toad, it made a lovely side dish.

Delish! Just be careful not to let the cream/milk mixture boil over as I did when I took my eye off it while slicing the veg! What a mess.

Tried this very yummy :o)

I tried this recipe but used low fat creme fraiche instead of double cream for the sauce; as karin said before when using low fat it split and was a little watery. However, the taste was good; just make sure all slices of cerleriac and potato are same thickness(thiness??) otherwise you get uneven cooking.

We tried this when I first saw the recipe in GF magazine....it looked sensational in the pictures and it tasted even better in real life. Highly recommended for an indulgent treat!

Fabulous! Very easy to make and delicious to eat. Tastes sensational and will be a regular accompaniment. Cooked with the Nick Nairn venison recipe from GF site.

will try this looks great!

We really liked the taste of this dish, but as I had no regular milk I used the low fat kind together with heavy cream, and the sauce "split" turned all watery and lumpy. What did I do wrong?
