There’s two ways to go about this. If your pasta was made with sauce and then put in the fridge to use later, you can just serve some into a bowl, make sure there’s enough sauce and then heat it up – either in the microwave or the oven.
If you have just boiled pasta and then put it away, it’s a little longer process. Heat up your pasta sauce in a pan and then add the boiled pasta to the sauce and heat it all up together till nicely warm and mixed up.
And then you’re done!
