# Expert Advice:

01 -
  • It packs 23 grams of protein per serving, which keeps you full without that heavy, sluggish feeling afterward.
  • You can prep the whole thing in about fifteen minutes and then let the oven do the work while you shower or chase kids around.
02 -
  • Do not skip squeezing the moisture out of frozen spinach because I made that mistake once and ended up with a watery mess that took an extra twenty minutes to set.
  • Under baking slightly is better than over baking because the casserole will finish cooking as it rests and stays creamier that way.
03 -
  • Whisk the eggs and cottage cheese longer than you think you need to because a smoother base means a more uniform texture throughout the entire bake.
  • If you want those gorgeous golden spots on top, flick your oven to broil for the last two minutes but stand right there watching because it goes from perfect to burnt in seconds.
