Dairy-free cheesy potato gratin recipe

This is a super-cheesy, super-saucy variant on the traditional potato gratin which can be served as a filling accompaniment to a variety of dishes. This follows on from yesterday’s cheesy vegetable bake recipe, as I made this a day later (once we finally had some potatoes).

What’s the difference between potato boulangere and potato gratin? A boulangere is a dish where thin slices of potato are put in an ovenproof dish, drowned in a sauce of cream and chicken stock, and baked until the potatoes at the top are crispy. A gratin, traditionally-speaking, is a boulangere with cheese on top. As you can see, the traditional version needs some big changes to make it dairy-free and vegan!

Every Sunday, and at Easter and Christmas, my aunt used to do a stunning roast dinner, and one of my favourite things on the dining table was a big bowl of potato boulangère with the delicious crispy slices of potatoes on the top and soft, saucy potato slices underneath. I loved it. When I had to cut out dairy many years ago after developing CMPA, I thought I’d never get to eat it again.

Sometime in 2012, my aunt gave me a dairy-free potato boulangere recipe and I was very happy to be able to enjoy one of my favourite dishes once again.

Since then, we’ve had four house moves across three countries (and two continents) and I have lost my potato gratin recipe. In the absence of a structured recipe, I devised this dairy-free cheesy potato bake a few days ago as a vegan side dish to go with the Lidl vegan Christmas roast they were selling very cheaply in January. It would also work well with Linda McCartney vegetarian quarter pounders, although you would need to add the quarter pounders to the oven about halfway through cooking this potato bake.

Ingredients:

5 medium-sized potatoes

Dairy-free white sauce (recipe here) or cheese sauce (recipe here). I recommend the white sauce.

100g grated cheese

You can totally cheat on the sauce and use one of plenty of options, such as Asda’s bechamel sauce (white sauce), or Sacla’s Vegan Ch**se sauce, both of which are sold in jars, or Tesco’s instant dairy free cheese sauce mix sachets (do NOT buy the ASDA cheese sauce sachets; they are NOT dairy free, only gluten free).

Method:

Peel the potatoes. Chop into thin slices. Fill a medium-sized glass dish with them.

Make up the white sauce (or cheat and open a jar of it) and cover the potatoes with it.

Cook on 150 degrees for 30-35 minutes then cover with grated cheese. Turn up the temperature of the oven to 180 and put the dish back in the oven and cook for the last 10 minutes, until the cheese has melted a bit and is starting to go crispy.

If you mess this up (as I did this one time) and put the cheese on too soon, just put the food in the oven and keep the oven at 150 for 20 more minutes.

To check if it’s ready, try sticking a fork into one of the slices of potato. If it feels hard, it’s not ready so put it back in the oven. If it’s soft, it’s ready to serve!

Dairy Free Cheesy Vegetable Bake

Being dairy-free, the thing I miss the most is cheese. When I first became a vegetarian back in 2007, I didn’t much care about cheese, but over the next twelve months, I really discovered it. Wensleydale. Stilton. Halloumi… I’d never tried such delicious things. I grew up in a house where “cheese sauce” came out of an instant Bisto tub with some hot water added. So the world of proper cheese was a huge discovery for me (and a double-edged sword, when I found out it actually makes me ill as I have non-IgE CMPA).

Despite being dairy-free, I do still try to enjoy cheese (soy or coconut cheese, these days) and I still create recipes that include it. The biggest thing you need to know about dairy-free cheese is it’s not a source of protein (unlike animal cheese) so you need to compensate for that by including protein in your daily diet.

One of my favourite foods is cauliflower cheese, and that’s what this dairy-free vegetable bake is based on (but using more veg for variety).

Thankfully, this recipe is both gluten-free and dairy-free (and vegan) so it’s perfect for anyone with those dietary requirements. It’s also low-carb.

Originally, I wanted to make something resembling a potato gratin, but I’d forgotten the recipe and couldn’t find it anywhere (it’s probably on this blog somewhere). Then it turned out we had no potatoes so I gave up on that, and did this sort of cauliflower cheese vegetable bake thing instead. It uses broccoli, cauliflower and peas, but if you only have broccoli or cauliflower you can use one instead of both.

This takes about 10-15 minutes to prep (it might be a little slower if you do the white sauce from scratch using my vegan white sauce recipe but you’ll get faster at the white sauce the more times you make it) so it’s great as an addition for a dinner party, Sunday lunch or a special occasion, or just to liven up weekday meals, if you’re doing something that takes a little longer to cook than usual, such as a nut roast. If you’re dairy-free but non-vegan, you could serve with salmon or another oily fish.

This could also be a lunchtime main if you added some chopped vegetarian sausages or a healthy sprinkling of sunflower seeds to add protein, if you’re looking for vegan recipe ideas or inspiration.

Dairy free cheesy vegetable bake recipe

Ingredients:

100g broccoli

100g cauliflower

50g peas

250ml dairy free cheese sauce or white sauce

about 100g grated cheese

This recipe is super-easy, and there are plenty of options if you want to “cheat” at making the sauce, such as Asda’s bechamel sauce (white sauce), or Sacla’s Vegan Ch**se sauce, both of which are sold in jars, or Tesco’s instant dairy free cheese sauce mix sachets (do NOT buy the ASDA cheese sauce sachets; they are NOT dairy free, only gluten free).

To make a “proper” dairy free white sauce, use my easy three-ingredient recipe available here.

Method:

First, chop any large broccoli florets and cauliflower florets in half. Now put all the veg into a large saucepan and boil for about 10-15 mins until it’s soft.

While the veg are cooking, make your dairy-free white or cheese sauce.

Drain the veg and put into a large glass oven-safe dish (such as a Pyrex one).

Pour the sauce over the top.

Cover with grated cheese and bake at 160 degrees Celsius/gas mark 5/350F for about 15 minutes until cheese is melted.

Serves 4.
