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.

• Mash the florets to your desired consistency. Add softened butter, cream cheese, garlic and heavy cream.

• Add fresh lemon juice, prepared horseradish, Parmesan cheese, salt, and pepper. Stir well.

• Add frozen peas and mix. Add the mixture to a 1½ quart baking dish and bake in a preheated 350-degree oven for 20-25 minutes. Serve hot.

Cauliflower has been enjoying a complete surge of popularity over the past few years! I don’t know who cauliflower’s publicist is, but whoever it is, they sure are doing things right! 😉
