This Vegan Cauliflower Cheese bakes whole cauliflower quarters, leaves and all, in a creamy, cheesy cashew sauce until golden. It takes about 25 minutes, serves 6 as a side and you can make it ahead and freeze it, which makes Christmas Day so much easier. It is lovely next to my Rosemary Roast Potatoes.

Why this recipe works
I have a dairy allergy, so a good cauliflower cheese was one of the things I missed most. This one is so rich and cheesy that nobody at the table notices there is no cheese in it. Whether it is for Christmas dinner or your weekly Sunday roast, the golden top and the smell coming out of the oven will win everyone over.
It is my favourite side with a roast, especially around Christmas, next to my Vegan Yorkshire Puddings (Gluten Free) and Smashed Brussels Sprouts. With just 7 simple ingredients, it is a dish you will make again and again.
You will find it in my 29 Vegan Christmas Recipes roundup.
Ingredients to make Vegan Cauliflower Cheese

- Cauliflower: One whole cauliflower, cut into quarters with the leaves and core left on. They add texture, colour and flavour, cut down on waste and make it look impressive. Spare cauliflower? Try my Cauliflower Soup, Cauliflower Curry or Bang Bang Cauliflower.
- Cashews: Soaked in hot water for 5 minutes, they blend into a smooth, creamy base for the sauce.
- Dijon Mustard: A teaspoon adds a little tang that cuts through the creamy sauce.
- Olive Oil: Adds richness to the sauce.
- Unsweetened Almond Milk: I find it works best here. I use Rude Health because it is quite thin.
- Nutritional Yeast: The hero ingredient. It gives the sauce its nutty, cheesy flavour. Find it in most supermarkets in the free from aisle.
- Salt and Pepper: A pinch of each in the sauce. Taste it before it goes over the cauliflower.
See recipe card for full information on ingredients and quantities.
Substitutions
- Dijon Mustard: Wholegrain mustard works too.
- Almond Milk: Any unsweetened plant milk, such as oat milk, works. Almond milk gave me the best results.
- Broccoli: Use a head of broccoli instead of cauliflower, or half and half. My Air Fryer Broccoli is another easy side.
- Nutritional Yeast: No nutritional yeast? Scatter 100g of grated vegan cheese over the top before baking.
- Cashews: For a nut free sauce, use 50g of sunflower seeds, soaked in boiling water for 10 minutes. The sauce is a little less creamy.
Variations
- Kid Friendly: Leave out the Dijon mustard for a milder sauce. Not a cauliflower fan? Stir the sauce through pasta instead, or make my Vegan Mac and Cheese.
- Crunchy Topping: Blitz a slice of gluten free bread with a tablespoon of nutritional yeast and a little fresh rosemary, then scatter it over before baking.
How to make Vegan Cauliflower Cheese

Step 1: Preheat the oven to 200°C fan (220°C conventional, gas 7). Cut the cauliflower into quarters, leaving the leaves and core on. Simmer in a large pan of boiling water for 5 minutes, then drain really well.

Step 2: Meanwhile, soak the cashews in hot water for 5 minutes, then drain. Blend them with the almond milk, nutritional yeast, olive oil, Dijon mustard, salt and pepper until smooth. Put the cauliflower in an ovenproof dish and pour the sauce over.

Step 3: Bake for 15 to 20 minutes, until golden and bubbling. It is a great one to bake alongside my Hasselback Potatoes.
Leftovers
Cool leftovers quickly, keep them in an airtight container in the fridge and eat within 2 days. Reheat once, in the oven or microwave, until piping hot all the way through. To get ahead for Christmas, make it up to the point where it goes in the oven, then freeze it in its dish for up to 3 months. Defrost in the fridge overnight and bake for 25 to 30 minutes, until golden and piping hot. Leftover cauliflower cheese is lovely stirred through my Broccoli Pasta.
Recipe FAQs
It is a classic side for a roast. Serve it with my Roast Parsnips and a Christmas Nut Roast for Christmas dinner.
Cashews, nutritional yeast and unsweetened almond milk, plus a little olive oil, Dijon mustard, salt and pepper, all blended until smooth.
Usually the cauliflower is overcooked or not drained well. Simmer it for just 5 minutes (less for a small cauliflower) and let it steam dry in the colander for a minute before the sauce goes on.
Yes, briefly. A 5 minute simmer softens the thick quarters so they cook through in the oven at the same time as the sauce turns golden.
Yes. Assemble it, then freeze it before baking for up to 3 months. Defrost in the fridge overnight and bake for 25 to 30 minutes, until golden and piping hot.

Absolutely love this recipe. Have really missed cauliflower cheese since turning vegan from vegetarian….loving this!
Thank you Paula 🙂 so pleased you enjoyed it!
This was absolutely delicious I added some garlic to my sauce and sprinkled vegan cheese on top, I may double the sauce next time as it absorbed quite a lot.. thanks for an awesome recipe
Thank you Lea, so pleased you enjoyed it 🙂
Excellent vegan cauliflower cheese! We added leeks, because cheesy leeks are awesome, and it was really delicious. The ‘cheese sauce’ tastes good before cooked in the oven, but soooo much better afterwards. My mum and I adopted a vegan diet about 4 months ago (from vegetarians), and we both loved this recipe. It’s better than using vegan cheese bought from the supermarket, and healthier too. The meat eater at the table also loved it, and so did my 1 year old.
I will reccommend this to other people for sure.
Hey Olivia, So pleased to hear you all enjoyed it! Thanks for sharing your feedback 🙂
Hi, have only just found you and am looking forward to trying your vegan recipes, They look so good and yet so quick to make.
Would almonds work instead of cashews for the sauce? Thanks for your great recipes, Sandy
Hey Sandy, thanks for following 🙂 Never tried it myself but give it a go. They may need soaking for longer in hot water to soften. Let me know how you get on!
Just tried this with almonds instead of cashews (we’d run out). Delicious! Very pleased with this recipe as i wondered if vegan cauliflower cheese would work – and now found that it does!
This is an absolute game changer. Thanks so much for sharing, it’s amazeballs.
how much is 200 ml in cups
3/4 cup
Can you make the sauce without the oil?
Yes! Just add a splash more milk 🙂 let me know what you think.
How would you serve this? Would you serve it with a bunch of other cheese, bread, crackers, and fruit; like a cheese plate?
Hey Louis, I serve it as a side to a Christmas dinner or Sunday roast.
I’ve never heard of cauliflower cheese, but now I need to try it! Looking forward to this! So simple!
I have just made & eaten this. One word describes it. Wow.
It is so easy & tasty. Just go & make it you won’t regret it
Thank you Catherine 🙂 so pleased you enjoyed it!
