Tips for the Best Instant Pot Mac and Cheese

Mac and cheese is the ultimate comfort food. Follow these tips for best results when making it in an electric pressure cooker like the Instant Pot.

1. Can I use almond milk?

I have used almond milk to make mac and cheese in my Instant Pot, and I have to say… I don’t recommend it.

The flavor of almond milk just doesn’t go too well with cheddar! I haven’t found a milk alternative that tastes as good as regular milk, heavy cream or evaporated milk in this recipe.

2. Can I use pre-shredded cheese?

No, it doesn’t work the same. The pre-shredded cheese you buy in bags at the grocery store has cellulose added to keep the shreds from sticking together. This causes pre-shredded cheese to melt very differently from freshly grated cheese and it doesn’t work well with Instant Pot macaroni and cheese.

3. What other cheeses taste good?

There are a lot of different cheeses you can use, and a combination is often better than a single cheese. I like to add some parmesan cheese in for a pop of flavor.

Pepperjack is delicious if you want mac and cheese with a kick. Gruyere gives a really rich flavor. A fun thing to do is experiment with a new type of cheese each time to find your family’s favorite combination of cheeses!

4. Ways to add more flavor?

Cook with chicken stock or beef bone broth instead of water. Onion powder and garlic powder can add extra flavor as well.

5. Cook time for al dente pasta?

We prefer our pasta fully cooked vs al dente, but if you prefer the latter, reduce the cook time to 3 minutes the first time. Then you can adjust up or down by 1 minute the next time you make it if it’s not quite to your preference.

6. Can I double this recipe?

Yes, I have successfully doubled this recipe many times in a 6 quart and 8 quart Instant Pot.

7. Can I use regular elbow macaroni or another brand?

I haven’t found a brand of gluten free pasta that works in the Instant Pot as well as Barilla does. And while this recipe is written specifically for Barilla gluten free pasta, it works with regular pasta too if not everyone in your house is gluten free.

8. Make it a kid-friendly meal

9. How to make it a main dish?

If I’m having a busy day and want to make a one pot mac and cheese main dish, I like to sauté a pound of Italian sausage in my Instant Pot first, then add the water and noodles as described in step 1 above.

Pour in a couple cups of frozen peas on top and cook as indicated in the recipe above. When you open the lid, stir and you’ll have a tasty one pot dinner.

10. How to store leftovers?

While gluten free pasta doesn’t have the best texture the next day, leftovers can be stored in the refrigerator in an airtight container for 2-3 days.

11 .Where to buy groceries online?

I’ve been doing more and more of my shopping online. Check out the best websites for ordering produce, meat and seafood online
