Cauliflower is one of those magical vegetables that can be morphed into just about anything these days. However, my favorite way to eat it is in this Easy Cheesy Cauliflower Casserole.

I developed this recipe because we’ve been following a keto eating plan in my household. That said, I’ve served this dish to several people who aren’t following a keto plan, and also to one person who doesn’t enjoy cauliflower at all, and they all approved of this delicious and slightly zippy side dish. WIN!

Cheesy Mashed Cauliflower Casserole with Peas is super simple to make, and you can mash the cauliflower to your desired consistency. For this recipe, I like to keep the cauliflower a little chunky, so it has more body than your typical mashed cauliflower side dish. But feel free to mash it to whatever fits your preference.

Since this dish is heavily laden with cheese, cream, and butter, the importance of the horseradish and fresh lemon juice at the end cannot be overstated!

The fresh lemon juice cuts through the richness of the other ingredients and balances the flavors of this Easy Cheesy Mashed Cauliflower Casserole in a wonderfully delicious way, and the horseradish adds a little zip that wakes up the entire dish!

Here are the easy steps for making Easy Cheesy Mashed Cauliflower Casserole with Peas;

  • Cut or break the florets off the cauliflower head. Discard the core and leaves. Add the florets to a large bowl. Cover with plastic wrap and microwave for 10 minutes until soft and tender.

  1. My husband claims not to like cauliflower, but with this recipe, I have no doubt he will be in love in no time!!

  2. Can you sub sour cream for the cream cheese

    • Hi, Melissa!
      You can, but then I’d suggest leaving out the lemon juice. Since the sour cream already has a tangy acidic flavor, the lemon juice would be overkill (in my opinion).
      Also, the completed dish may be a tiny bit thinner in consistency, but it should be objectionable.
      Thanks for the question.
      Take care,
      Renee
