  • Bake the casserole at 350 degrees for 45 minutes. Let rest 5-8 minutes before serving.

Notes

  • Make sure to drain the broccoli well. If you skip this, your casserole will be watery.
  • For an extra rich souffle, use cream or half and half instead of milk.
  • The broccoli souffle must rest when it gets out of the oven so it has a chance to set up.
