Gluten Free Cauliflower Cheese

I love cauliflower cheese and my Gluten Free Cauliflower Cheese recipe has to be my favorite version. The gluten free cheese sauce is made with double cream (heavy cream) and contains no flour of cornflour.

This is the best cauliflower cheese recipe I have come up with. I love cauliflower cheese and eat it regularly as a main dish, when I don’t want meat. However, my family have never shared that love until now.

With this easy cauliflower cheese recipe I find they are all tucking in. The lack of flour and extra flavour bomb ingredients in the sauce make this a dish they all enjoy. Which sadly means I rarely have any leftovers for an easy lunch the next day!

I first started experimenting with this recipe when my Mum was diagnosed coeliac. Like me, she loves cauliflower cheese, but can’t eat a bechamel based cheese sauce. Neither of us are keen on cornflour, so I needed to come up with a cheese sauce without cornflour too.

I make my gluten free cheese sauce without cornflour and flavor it with sauteed leek, some chopped sun-dried tomatoes and a fresh burst of green onion. This packs in so much flavour.

Making gluten free cauliflower cheese without cornflour or flour, also makes the sauce suitable for anyone following a low-carb/keto diet. I don’t use too much sun-dried tomatoes, but if following a keto diet and want to make a truly Keto Cauliflower Cheese, you may prefer to swap them for fresh tomatoes or leave them out altogether.

Why you’ll love this recipe:

• Make ahead earlier in the day, or the day before and bake in the oven when you are ready to serve.
• Hands on prep time is minimal, as the sauce is made in a matter of minutes.
• The gluten free cheese sauce contains no flour or cornflour making it suitable for Coeliacs or anyone following a gluten free diet.
• A great way to get kids to eat cauliflower – my kids would not touch regular cauliflower cheese (believe me I’ve tried) but they love this version with the added flavours.

How to make gluten free cauliflower cheese

• Preheat the oven to 200C/180CFan.
• Cut the cauliflower into florets and add to a pan of boiling salted water. Reduce the heat to medium and cook the cauliflower for 6-8 minutes. Test the cauliflower, it should be soft, but retain a little bite.
• When ready, drain the cauliflower in a large sieve and set aside to steam for a minute or two to drain completely. Then add to an oven-proof dish.
• While the cauliflower is cooking, get on with making the sauce. Melt the butter in a small saucepan, over a medium heat, and add the leeks and a pinch of salt. Cook the leeks for 5 minutes.
• Now add the double cream and 140g of the grated cheddar cheese. Heat gently, stirring constantly, to melt the cheese.

• Place the cornflour into a small bowl. Remove some of the creamy sauce into the bowl and stir through the cornflour to form a smooth paste. Return the cornflour mixture to the saucepan and stir through the sauce. Keep stirring until the sauce thickens.
• Remove the sauce from the heat and stir through the spring onions, sun-dried tomatoes and diced mozzarella cheese.

• Season the sauce to taste with salt and black pepper, then pour over the cooked cauliflower.
• Scatter the remaining 60g of grated cheddar cheese over the top of the dish, and place into the hot oven to bake for 20 minutes.
• Remove from the oven and serve immediately.

Recipe ingredients & substitutions

• Cauliflower – I use 1 head of medium-sized cauliflower (cut into florets) to serve 6 as a side, or 3 as a main meal.
• Butter – you can use either salted or unsalted butter to saute the leeks.
• Leek – I use I medium-sized leek, trimmed, quartered and sliced.
• Cream – I use double cream (heavy cream) for the sauce as it has a thick consistency. This stops you needing to add flour or cornflour to thicken the cheese sauce.
• Cheese – I use both mature cheddar cheese and some drained and diced mozzarella cheese in the sauce. Further grated cheddar is added to top the dish before baking in the oven.
• Onion – I use spring onions to flavor the sauce and add a little extra freshness. You could swap the onions for chives.
• Tomato – I use sun-dried tomatoes in oil, which I drain and chop before adding to the sauce. Not only do they have an intense tomato flavor, but I find they add less water to the sauce than fresh tomatoes would.
• Seasoning – I season the sauce with sea salt and freshly ground black pepper.

Recipe variations

• Swap the mature cheddar cheese for another strong flavored cheese like Gruyere or Parmesan cheese.
• Want to add in more vegetables, no problem. Try sauteing some mushrooms, carrots, bell peppers, or red onions along with the leek.
• Stir some freshly chopped herbs, like chives, garlic or parsley, through the cheese sauce.
• This recipe would work equally well for broccoli or romanesco. Or try a mixture of both broccoli and cauliflower.
• A teaspoon of mustard can be added to the sauce, if you want to add some sharpness.

Serving suggestions

This cauliflower cheese recipe will serve 6 as a side dish or 2-3 as a great tasting vegetable main. If serving as vegetable main dish, I like to add a couple of extra vegetable sides. However, I usually keep those simple, something like some steamed carrots, garden peas, or green beans. If adding a potato I also go with something simple like a steamed or boiled new potato.

Useful hints and tips

1. Double or treble the recipe if you are feeding a crowd.
2. Following a low-carb diet? I don’t use too much sun-dried tomatoes, but you may prefer to swap them for fresh tomatoes or leave them out altogether.
