Mac and Cheese Sauce Without Flour: How To?

Last Updated on January 18, 2022

Today, we’re going to look at how to make mac and cheese sauce without flour. Making mac and cheese with no flour is actually much easier than you may expect! Macaroni and cheese is a favorite across the world, but particularly in the US. It’s creamy, cheesy, and actually one of my favorite foods to eat. But is it gluten-free? And how can you make it without using flour? Let’s take a look.

Ingredients In Mac And Cheese

While you can make macaroni and cheese as fancy or as basic as you’d like, the basic ingredients tend to remain the same throughout. The main ingredients in mac and cheese are:

  • Macaroni (Elbow Pasta)
  • Milk
  • Butter
  • Flour
  • Salt
  • Pepper
  • Cheese (at least cheddar cheese, but often more than one type of cheese – parmesan is another great choice to use!)

Is Mac And Cheese Gluten Free?

Unfortunately, macaroni and cheese are not gluten-free. Traditional macaroni pasta is not gluten-free, as well as flour. Unless it specifically states that it’s gluten-free mac and cheese, there’s a high possibility that it will contain gluten.

Pasta is one of the main food products that contain gluten and one of the first foods I cut out of my diet to make the transition to a gluten-free diet.

How To Make Cheese Sauce Without Flour

Let’s take a look at how to make a gluten-free mac and cheese sauce without using the enemy that is wheat flour! It’s important to note that you need to also use gluten-free elbow macaroni pasta when making the recipes we’re looking at today. Most other ingredients will be naturally gluten-free, but always be sure to check ingredient labels.

How To Thicken Cheese Sauce

If you’re looking for ways to thicken your cheese sauce without flour because it doesn’t have the consistency you like, there are a few easy ways to accomplish this. Check out our top ways.

  • Cornstarch. Add one or two teaspoons of cornstarch to half a cup of water. Mix well to make a slurry. Now add the cornstarch mix to the sauce gradually until you reach the desired consistency. Allow to simmer for a few minutes to ensure the cornstarch flavor is no longer there.
  • Extra Simmer Time. It really could be as easy as letting it simmer for longer. Simmering is a foolproof way to thicken the sauce – it just may take time. This is a great option if you don’t have any thickening agents to hand.
  • Egg Yolk. Whisk an egg yolk separately and gradually add it to the cheese sauce. Do this over low heat, and be sure to mix in well. You may not need the entire egg yolk
  • More Cheese. If you love your cheese, this is a great option (while not the healthiest!). More cheese will thicken the mix instantly and make it taste even cheesier – which is always a good thing for me!


I hope this article has helped you to become more familiar with how to make mac and cheese sauce without flour. I did say it was easier than you may expect! Be sure that any ingredients you add to your cheese sauce are gluten-free – as gluten can sneak it’s way into the most unexpected of foods.
