What kind of cheeses are best for mac and cheese?

Using a combination of cheeses will give you the best flavor and texture. I use a mixture of sharp cheddar and Parmesan.  However, you could also use fontina, gouda, or gruyere.

TIP: Use freshly grated cheese instead of pre-shredded in a bag. The bags tend to contain a starch or anti-clumping additive. This changes how shredded cheese will melt and the creamy consistency in your mac and cheese.

Ingredients

  • elbow pasta
  • water or broth 
  • salted butter
  • salt and pepper to preference 
  • garlic powder
  • extra-sharp cheddar and Parmesan cheeses
  • evaporated milk OR light cream/whole milk 

Instructions

  1. Stir the pasta and water or broth together in the inner pot along with the butter and seasonings. 
  2. Secure the lid and set to sealing, and use the Manual mode for 4 minutes. 
  3. When the cooking time has ended, let the pot Natural Pressure Release for ONE minute. This one minute is important to make sure the starch from the pasta has enough time to settle down a little bit (vs spewing out of the steam valve, a huge and dangerous mess).
  4. Cover the steam valve with a clean damp cloth then carefully release the pressure. 
  5. Remove the lid and stir well. 
  6. Mix in the cheese a little at a time and the evaporated milk. The sauce will thicken as it sits for a few minutes. 
  7. Taste and adjust your seasonings as needed.

Recipe Variations

Mac and Cheese is pretty incredible all on its own, but if you’ want to dress it up a little, here are some mix in and topping ideas:

  • Add 2 cups of steamed veggies such as broccoli florets after the mac and cheese is done cooking.
  • Cook, drain and crumble 8 slices of bacon and sprinkle over the top.
  • Stir in rotisserie or leftover chicken for added protein.
  • Melt 2 tablespoons of butter in a skillet and add 1 cup of panko breadcrumbs. Cook until toasted and sprinkle over the top of the pasta.
  • Stir in diced ham and a 1/2 teaspoon of ground mustard.

What Goes With Mac and Cheese

Since mac and cheese can be heavy, I like to serve it with something a little lighter. My Lemon Vinaigrette is delicious on a side salad or steamed broccoli. Here are some of my other favorite sides to serve with this cheesy goodness!

How to Reheat Mac and Cheese

Let’s face it, it’s really hard to reheat mac and cheese and have it taste as good. My trick is to add about 1 tablespoon of whole milk or light cream for every cup of pasta.

You can reheat it in the microwave, but I prefer the stovetop on medium-low heat where you can keep an eye on it.
