How to Make the Perfect Béchamel?

Béchamel is one of the 5 basic sauces of French cuisine.

It is often used in recipes such as Lasagna Recipe without Ricotta Cheese, Greek Moussaka (Mousaka), Smoked Gouda Mac and Cheese, and Easy Fish Pie with Leeks.

Although it is very simple to make the béchamel sauce, there are a few basic rules to make it properly:

• Firstly, stir the béchamel constantly: Melt the butter and stir in the flour until it forms a roux, whisk as you add the milk gradually. Make sure to move the whisk around the entire pan, too, whisking around the sides and across the base to stop the sauce from catching.

• Secondly, use the right ratio of ingredients: Use an equal amount of butter and flour to start the roux, and then add the milk gradually until the desired consistency.

• Lastly, add the milk a little at a time: If you add the milk all at once, the roux will get lumpy.

Ingredients You'll Need

Please scroll down to the recipe card below for the full ingredients list with measurements, complete recipe method, recipe notes, and nutritional information.

• Head of cauliflower - It is a healthy and delicious vegetable full of nutrition. Use fresh cauliflower with clear white fleurets for the best results. You can use half broccoli and half cauliflower for this recipe.

• Butter - Use good quality unsalted butter. To make the bechamel, make sure it is totally melted before adding the flour. 

• Milk - I use full-fat or semi-skimmed milk for the bechamel sauce. Add it slowly in small batches to the butter and flour mixture for a velvety sauce.

• Nutmeg - It is the perfect spice for the bechamel sauce. I use freshly grated nutmeg for more intense flavor and freshness.

• Cheddar Cheese - Mature or extra mature cheddar adds a bit of kick to the sauce. You can substitute it with gruyere or gouda.

• Breadcrumbs - I use panko breadcrumbs for extra crispness but you can use any type of breadcrumb you have in hand. You can substitute it with cornflakes. Just blitz it in a food processor before using the cornflakes.

How to Make Cauliflower Cheese Bake?

This is a very simple recipe with a few easy steps that you need to follow to achieve the best results:

Parboil the Cauliflower

Trim the whole cauliflower head and then cut it into bite-sized florets.

In a large saucepan, bring enough water to boil and cook the florets for 6 to 8 minutes, until firm but tender.

Put the florets in a colander and let them drain while preparing the cheese sauce.

Prepare the Cheese Sauce

Preheat the fan oven to 180° C (360° F).

To make the cheese sauce, melt the butter in a saucepan on medium heat and stir in the flour.

Mix well using a wooden spatula or a whisk and cook for two minutes stirring all the time.

Whisk in a little of the warm milk at a time stirring continuously until you have a smooth, velvety sauce.

Cook on low heat for a few minutes stirring all the time until the sauce has thickened and the flour taste has disappeared.

Remove the pan from the heat and whisk in the salt, nutmeg, and 100 g of the shredded cheese.

Although this cauliflower bake is traditionally made with cheddar cheese, you can replace it with any other hard cheese you like.

Combine and Bake

Place the drained cauliflower in a 23 cm (9") Ø oven dish or a casserole dish in a single layer, then pour the creamy sauce over it.

Give it a quick stir to combine the cheesy sauce with the cauliflower.

Sprinkle the remaining cheese and breadcrumbs on top.

Place the baking dish in the preheated oven.

Cook it for about 35-40 minutes, until it's bubbling inside and golden brown outside.

Top Tips From the Chef

• Cook the cauliflower al dente, overcooked cauliflower makes the Cauliflower Cheese Bake watery.

• Let the cooked cauliflower fleurets drain and ensure they are totally dry before mixing them with the cheese sauce.

• The homemade cheese sauce (a.k.a white sauce) is the most crucial element of this entire recipe. You can refer to the tips above and watch the video on the recipe card to master the art of creating a perfectly silky béchamel sauce every time.

• Don't skimp on the cheese, this deliciously cheesy cauliflower side dish is meant to be cheesy!
