Celeriac & Potato Gratin (3 Ways)

I’ve received quite a bit of celeriac in my veg. box delivery from Oddbox recently. My go to recipes with celeriac are normally soup & mash but I do like to vary my meals as often as possible and this week my partner suggested a gratin. As I already had potatoes and onions in the cupboard, it seemed like the perfect accompaniment to serve with Pork for a Sunday Dinner. There’s loads of recipes for celeriac gratin on-line, but here is my attempt. Feel free to adjust the quantities of celeriac & potato if you have different amounts to use up.

INGREDIENTS

  • Half a celeriac (approx 500g.) chopped in similar size pieces to the potato. (I peel with a knife post boiling as find it easier)
  • 600g potatoes halved or quartered depending on size. (I didn’t bother peeling but this is completely up to you)
  • 2 x small onions, finely sliced
  • 150ml cream
  • 150ml milk
  • Knob of butter
  • 2 x cloves of garlic
  • 1 x sprig of rosemary

METHOD

Parboil the celeriac & potato for 10 mins (I start with cold water & start the 10 mins when the water starts to boil)

Melt knob of butter in pan and slowly cook the onions over very low heat for 10 mins, or until they start to brown.

Add cream, garlic, rosemary and enough milk to cover the onions, bring to a simmer and then simmer very gently for 10 minutes. After the 10 minutes is up, remove the garlic cloves & rosemary sprig.

Slice the potatoes & celeriac thinly (I use a mandolin) & roughly layer in an ovenproof bowl pouring over some of the cream & onion mixture after each layer.

Top the final layer with any remaining onion mixture, and bake in the oven at 180c for approx 1 hour or until golden brown.

This dish is such a rich, hearty and alternative side to a Sunday roast and it makes for incredible leftovers. I think gratin is one of those dishes that almost tastes better second time around. On this occasion, I completely mixed up the leftovers and served with fried pancetta and fried egg for a incredibly tasty and wholesome mid-week dinner.

My 20 month old son also enjoyed a portion of the gratin, he’s had celeriac a few times and I think originally found the taste maybe a bit too strong, but this time coupled with the cream, he ate every single last bite. Remember that celeriac is an allergen to if your child hasn’t tried it before, start with small quantities. My tactic with my son is to continue to expose him to as many tastes as possible and offer again and again even if he has refused the item on one occasion. It can be hit or miss but he’s generally a pretty good eater and the things he does enjoy often amazes me.

Parsnip & Potato Rostis (from left-over veg)

Glancing in my fridge on boxing day I was met with a huge array of left-overs giving me plenty of ammunition for a few experimental dishes.

We’d cooked far too many vegetables to accompany Christmas dinner, a common mistake when cooking up roasts, but being determined not to waste a morsel I’d kept all the surplus in the fridge. Some of the left-over vegetables had made it onto my boy-friends turkey sandwich – ‘a roast dinner sandwich’ (or a manwich in his words), which was pretty delicious but it hadn’t made a dent in the left-over roast potatoes, parsnips and baby carrots.

I’d seen Nigel Slater cook up some Bubble and squeak patties so I decided to do something similar with my left-overs. I mashed up all the potatoes, parsnips and carrots but the mixture was very dry, so for moisture I added a dash of left-over turkey stock and gravy. After adding seasoning, I divided the mixture into 4 (although the number of röstis will depend on how many left-over veggies you have) and moulded into patty shapes which were probably about 1.5cm thick.  I heated a knob of butter in a non-stick frying pan but was unsure of cooking time so I turned the röstis over every two minutes (I find if you turn too often the röstis start to fall apart). After a total of about 8 minutes, they were a nice golden colour and hot all the way through.

The röstis would make a delicious side dish but I also had some left-over stuffing from the turkey which I decided to serve with the röstis. I moulded the stuffing into thin patties, again adding some left-over stock for moisture and popped them in the oven at 200c for 15 minutes. Again I was unsure of timings so I kept my eye on them, the stuffing patties were very moist and I was unable to turn during cooking but after 15 minutes they had dried out and become golden.

To serve, I placed the stuffing ontop of the vegetable röstis and for the final touch I reheated a small amount of leftover cranberry sauce in the microwave. The röstis were absolutely delicious with all the flavourings of a roast dinner, they’d make a great starter or a light supper  and the best thing is that I’m pretty sure they can be made with any left-over vegetables. I’ll definitely be making them next time I cook too much vegetables.

This is the first time I’ve made something out of left-over cooked vegetables and it would be great to hear about what other people do with theirs.
