Tips and Notes

  • Pre-cook the cauliflower. Before assembling the casserole, be sure that you boil the cauliflower until fork tender. This creates that delicate, creamy cauliflower dish we’re looking for! No crunchy cauliflower here. 
  • Grease the baking dish. A light layer of cooking spray will do the trick. This helps prevent the creamy sauce of cauliflower from burning or sticking to the bottom of the pan. 
  • Bake uncovered. Exposing the topping to the heat is what allows it to turn deliciously golden-brown. 
  • If you do notice the cheese burning before the casserole is cooked all the way through, simply cover the pan with foil and continue to cook.
  • Add some extra crunch. Want a little bit more crispy crunch in your casserole? Try adding a layer of crispy bacon bits. 
  • Spice it up. Want even more flavor? Try adding in a sprinkle of garlic powder, onion powder, or even cayenne pepper for some extra heat. 
  • Make it cheesier. Try adding even more shredded cheese along with the parmesan. You could even do a whole cheese mixture with any combination of fontina, Monterey jack, sharp cheddar cheese, mozzarella cheese, or gruyere. 

Serving Suggestions

This cauliflower casserole is a delicious and versatile side dish! I love to serve it garnished with fresh green onions next to a number of different main dish options. Here are a few ideas:

Refrigerator: Leftover cauliflower casserole can be stored in an airtight container in the fridge for 4-5 days. Make sure that the leftovers cool completely to room temperature before storing. You can wrap the casserole dish tightly with plastic wrap or transfer the casserole to an airtight container to store. 

Reheat: To reheat leftovers, simply pop them back in the oven at 350ºF and cook until heated through. 

Freezer: I don’t recommend freezing this casserole. The texture can become watery when thawed. 

Frequently Asked Questions

Why is My Cauliflower Bake Watery?

There could be a couple of reasons that your cauliflower casserole came out too watery:

  • The cauliflower is over-cooked. Over-cooking the cauliflower can cause it to release too much moisture into the dish. For the best results, take it out of the oven after 25-30 minutes of baking.
  • The sauce wasn’t cooked long enough. Once your creamy sauce is mixed up, let it bubble slightly and cook for a few minutes. This allows it to thicken up properly.
  • It’s too warm. The casserole will naturally thicken up as it cools. Give it a few minutes to cool before serving to allow it time to set.
