Gordon Ramsay Lasagne White Sauce

Ingredients:

  • 25g unsalted butter
  • 25g plain flour
  • 300ml cold milk
  • Salt and pepper (to taste)
  • Pinch of nutmeg
  • 40–60g cheddar cheese, grated (quantity: to your taste)

Method Steps:

Prep the Roux:
Add the butter to a thick-bottomed saucepan and let it melt over medium heat. Add the flour and immediately stir vigorously with a spoon or spatula. Cook for about 1–2 minutes until it forms a doughy paste; this cooks out the raw flavour of the flour.

Add the Milk:
Pour in 1/3 of your cold milk and beat quickly with the whisk. Stir until well combined and smooth—don’t worry about lumps, just keep whisking. Remove the pan from the heat if it’s cooking too quickly; the residual heat will help as you mix.

Incorporate Remaining Milk:
Add the next third of milk and whisk vigorously. Then add the final third. Continue whisking until the sauce is smooth, thick, and lump-free.

Season:
Stir in a pinch of salt, pepper, and nutmeg. Taste and adjust seasoning as needed.

Finish with Cheese:
Add the grated cheddar cheese and stir until it melts through the sauce, creating a glossy, creamy texture.

Serve your cheesy white sauce over pasta, vegetables, or use for lasagne layering.

Sorting Out Your Béchamel

Mastering a plain white sauce opens up a world of culinary possibilities far beyond lasagne. For example:

  • Traditional Lasagne al Forno: Many authentic Italian recipes use a plain bechamel to allow the flavour of the ragù to shine.
  • Baked Pasta Dishes: It’s a great base for casseroles like pasta al forno or a simple macaroni bake before cheese is added on top.
  • Creamy Potato Bake (Gratin Dauphinois): Thin layers of potato are baked in a garlic-infused white sauce and cream.
  • Cream Soups: It’s the thickening agent for cream of mushroom, cream of chicken, or cream of celery soup.
  • Seafood Pot Pies: A plain bechamel is perfect for binding lobster, shrimp, or fish in a pot pie without overpowering the delicate seafood flavours.

White sauce for lasagne is called béchamel. Its butter, flour and milk. That’s all you need. In Italy they call it besciamella and it’s what goes in a proper lasagne to make it creamy.

The Lumpy Bit

Everyone gets lumps at some point. Just pour the milk in bit by bit and whisk it the whole time. Sounds dull but honestly that’s all you need to do. If you do get lumps anyway, push it through a sieve.

And don’t leave the pan to check your phone or whatever.

Couple of other things – don’t let the butter and flour go brown or you’ll end up with something that looks like gravy.

When it cools down it gets a skin on top which is annoying, so just put cling film right onto the surface of the sauce.

How Thick

You want it sort of medium thickness for lasagne – use about half a cup between each layer. It goes thicker when it cools down so you can always add more milk to loosen it up again.

Make Ahead

You can make it a few days before and keep it in the fridge, or freeze it for ages. Just make sure you cover it properly.

Other Stuff

For an authentic traditional lasagne bolognese you would use Parmesan. Some people add a bit of nutmeg but its not necessary – it depends on your tastes – only way to know is try it.
You can also use different flours for your lasagne white sauce but normal plain flour is fine.

Basically – slow with the milk, keep whisking, don’t let anything burn and you’ll be fine.
