Tremendously creamy, perfectly cheesy, and with delicious green chilis for a flavorful touch, this green chili mac and cheese is a new favorite in our household! But be careful – if you make it once, you’ll be asked to make it again and again!

🌶️ What Makes This Recipe So Good

  • Green chili mac and cheese is a really delicious take on the mac and cheese you know and love. There’s a rich and creamy cheese sauce, made with 2 types of cheeses, that gets an extra burst of flavor from diced green chile peppers. You know, “delicious” actually doesn’t cover it. “Incredible” isn’t enough, either. “Divine”, maybe?
  • Like our Cheetos pizza recipe, this is a dish inspired by St. Jude Children’s Research Hospital. Their cafeteria, Kay Kafe, makes a white green chili macaroni along with their traditional yellow macaroni, and after visiting the Kafe in person, I couldn’t resist making a version of my own.

👩🏼‍🍳 Chef’s Tips

  • Skip the prepackaged, preshredded cheeses. Instead, pick up blocks of cheese from the deli area and shred them yourself! It’s super easy to do, and the results are SO much better. The prepackaged stuff contains added fillers and starches to keep it from clumping. Those fillers also keep it from melting just like it should, which can make your cheese sauce grainy and unpleasant. Trust me. For the best green chili mac and cheese, shred your cheese at home.
  • Dairy products can curdle and seize if they’re cold when you add them to hot ingredients. Bring your milk, half and half, and cheeses to room temperature (or as close as possible) before cooking with them. Don’t rush it if you forget, either. If you warm them up too quickly, you get the same results.
