Notes

  • It seems crazy, but this mac and cheese soufflé has only 1 cup uncooked elbow macaroni. It's not a typo!
  • Cook and drain elbow macaroni before adding to this mac and cheese casserole. I typically cook it to a little less than al dente since it can finish cooking in the oven. 
  • Buttermilk might be an ingredient you keep on hand, so feel free to make your own. I do this all the time. Fill up your measuring cup with regular milk just below the 2 1/2 cup mark; add lemon juice or vinegar (approximately 1 tablespoon). Let sit for around 5 minutes to thicken.
  • If you are concerned about your baked macaroni and cheese getting cooked through with all those eggs, use a digital thermometer to check the temperature.  The internal temperature should at least be 160 degrees F. 
  • I can totally appreciate a skillet mac and cheese too.  If that's your cup of tea, check out this version.
