Recipe notes and tips

  • Use enough water so once the pasta begins to cook and expand, there will still be plenty of room for them to move freely.
  • To prevent sticking, stir your pasta as soon as you drop it in the water. 
  • Drain your pasta enough to remove most of the water without it drying off. If the pasta is too dry it’ll firm up and become too starchy.
  • Add hot pepper or chili flakes to make it spicy.
  • You can adapt with different proteins like shrimp, scallops, crabs or make vegetarian without proteins.
  • Reduce the amount of cheese and use milk instead of half and half if you want to make it lighter.
  • Season and taste as you simmer the mac and cheese.
  • You can also use precooked or rotisserie chicken, it’s also a good way to use up leftover chicken.

FAQ’s

Can I use other types of pasta?

As it’s mac n cheese, elbow pasta works great, but if you have bags of other pasta to hand then of course use them up! This Chicken Mac and Cheese works with many other types of pasta. The creamy cheesy sauce is awesome slathered over anything really! Shapes like penne, shells, rotini or fusili work great.

My sauce looks thin

If your sauce starts off looking a bit thin, fear not! The cheese sauce will thicken up as it simmers and even more so when you add the cheese. This sauce recipe is a great balance between metly but not too heavy.

How to store leftovers

You can store this Chicken Mac and Cheese in an airtight container, keep in the fridge fro up to 4 days. To reheat, place in the microwave or covered in the oven at 350F for 10-15 minutes.

You can also freeze leftovers for around 3 months. Allow the leftovers thaw overnight in the fridge. Freezing cooked pasta can make the texture softer.

    1. Hi Natalia,
      I haven’t tried but i think it will be fine. The flour is just to thicken up the sauce. And you can use gluten free pasta as well.
