  • Add as much or as little chili as you like. I find that about 4 cups of chili is the sweet spot to get lots of chili flavor while balancing out the mac and cheese portion. If you want more chili flavor add an extra cup. If you want more mac and cheese flavor, try adding just 2-3 cups of chili instead.
  • You can bake it with cheese on top or just serve it straight from the pan. They're both delicious. The shredded cheese on top just adds another layer of decadent flavor.
  • Shred your own cheese straight from the block. Pre-shredded cheeses are coated in cellulose which prevents them from clumping but also prevents them from melting well. Freshly shredded cheese will melt much better. Save some time and use the shredding attachment on your food processor to shred it in just minutes.
  • Spice it up! Add hot sauce or a pinch of cayenne pepper to add a kick to this chili mac recipe.
