This cauliflower casserole is the best way to get your veggie fix!

People pleasing is not a good trait to have, unless you’re a creamy cauliflower casserole.

IN THAT CASE: If you’re looking for a single side dish to serve at your next holiday gathering or family dinner that pleases just about every taste preference and diet under the sun, look no further, friends.

Tender, caramelized roasted cauliflower florets are hidden amongst indulgent, melting pockets of cream cheese, gruyere, and crispy bacon, a.k.a. you’ll question whether or not this dish actually contains vegetables (same goes for this Broccoli Bake).

Healthy swaps, like Greek yogurt and reduced-fat cream cheese, cut calories without sacrificing flavor. Yes, this is a creamy cauliflower casserole without mayo or sour cream! As a bonus, it’s also naturally low-carb.

Key Ingredients

You’ll find the full list of ingredients in the recipe card below, but here are some notes to keep in mind.

Cauliflower. Unlike raw cauliflower (which is bland), roasted cauliflower (like in this Roasted Vegetable Salad, for example) is complex, caramelized, and rich. We want bite-sized florets here; if you’d have to cut it with a fork on your plate before eating it, it’s too big for this cauliflower casserole.

Garlic Powder. All the garlic flavor without the fuss of actually chopping garlic.

Ground Nutmeg. My nod to the traditional flavors in a classic cauliflower casserole au gratin recipe.

Reduced-Fat Cream Cheese. Lends the ultimate creamy texture that ramps up the “loaded” factor of this dish.

Greek Yogurt. My sneaky swap for mayo or sour cream that keeps this cauliflower casserole creamy. You may also make this cauliflower casserole with low-fat sour cream.

Bacon. Turns this casserole into the stuff of dinner legend.

Cheese. Gruyere and Parmesan are the perfect nutty combination here! (This Brussels Sprouts Casserole is another side dish crowned with this tasty cheese combo.) If you don’t have Gruyere, any similar melty, alpine-style cheese will work wonderfully.

Chives. A beautiful addition of color and fresh flavor.

How to Make Cauliflower Casserole

Roast. Toss the cauliflower florets with the oil and spices, then roast until tender.

Cook and Crumble the Bacon. Here are more tips for Baked Bacon.

Make the Sauce. Mix together the cream cheese, yogurt, and shredded cheese. (Yes, it’s thick! It will melt and get smoother as it bakes.)

Finish. Remove the cauliflower from the oven, dollop with the cream cheese mixture, and sprinkle with the remaining cheeses. Bake the cauliflower casserole at 425 degrees F for 5 to 7 minutes until the cheese is melted and bubbly. Pop under the broiler to brown the top. Sprinkle with chives and additional bacon. ENJOY!

Recipe Variations

Loaded “Baked Potato” Cauliflower Casserole. Swap the Gruyere for sharp cheddar and the nutmeg for cayenne.

Fontina and Herb Cauliflower Bake. Swap the Gruyere for fontina, add 1/2 teaspoon dried thyme to the cauliflower prior to roasting, and top the final casserole with chopped, fresh parsley. Bacon optional…or not.

Italian. Swap the Gruyere for shredded provolone or mozzarella, omit the nutmeg, and add 1 teaspoon dried Italian seasoning plus a pinch of red pepper flakes to the cauliflower prior to roasting.

Meal Prep Tips

Here’s how you can make this cheesy cauliflower casserole ahead.

Roast the cauliflower 1 day in advance, then store in an airtight container in the refrigerator.

Prepare the cream cheese mixture 1 day in advance and store in the refrigerator.

When ready to cook, warm the cauliflower in a baking dish in a 350-degree F oven until hot.

Let the cream cheese mixture come to room temperature.

Increase the oven temperature to 425 degrees F, then dollop on the cream cheese mixture, top with cheese, and bake as directed.

What to Serve with Cauliflower Casserole

Chicken. Baked Chicken Cutlets would be a perfect side with this cheesy cauliflower casserole.

Pork. Crock Pot Pork Chops cook on your countertop while your oven is occupied with the cauliflower.

Beef. These Air Fryer Steak Bites are another option that cooks outside your oven.

More Sides. So many sides pair well with cauliflower casserole, from Sauteed Carrots to Roasted Garlic Potato Rolls.

Ingredients

2  medium heads of cauliflower cut into bite-size florets (about 3–4 pounds cauliflower, prior to being cut, or 5–6 cups florets)2 tablespoons extra-virgin olive oil1 teaspoon garlic powder¾ teaspoon kosher salt½ teaspoon ground black pepper¼ teaspoon ground nutmeg6 slices bacon4 ounces reduced-fat cream cheese at room temperature¼ cup nonfat plain Greek yogurt⅔ cup freshly grated Gruyere or similar melty, nutty, alpine-style cheese, divided¼ cup finely grated Parmesan cheese divided3 tablespoons fresh chives chopped

Instructions

Place racks in the upper and lower thirds of your oven and preheat to 425 degrees F. Lightly coat a wide 3-quart (9×13) casserole dish, with nonstick spray, and line a rimmed baking sheet with parchment paper.

In a large bowl, toss the cauliflower florets with olive oil, garlic powder, salt, pepper, and nutmeg.

Transfer the cauliflower to the prepared casserole dish and spread it into an even layer. Keep the bowl handy. Roast cauliflower on the lower rack for 30 minutes, until the florets are tender and begin to brown.

Meanwhile, arrange the bacon strips in a single layer on the prepared foil-lined baking sheet. Bake on the upper rack until crisp, about 10 to 15 minutes.

Remove the bacon and cauliflower from the oven. Stir the cauliflower, spread it back into an even layer, and place it on the upper rack to continue cooking until the end of its baking time.

Transfer the bacon to a paper-towel-lined plate and lightly pat dry. Once cool enough to handle, roughly chop or crumble the bacon into small pieces.

In the same bowl that you used to toss the cauliflower, beat together the cream cheese and Greek yogurt until combined. Stir in ⅓ cup Gruyere cheese, 2 tablespoons of Parmesan cheese, and half of the chopped bacon.

Remove the roasted cauliflower from the oven and dollop the cream cheese mixture over the top. Sprinkle with the remaining ⅓ cup of Gruyere and 2 tablespoons of Parmesan.

Return the pan to the upper third of the oven and bake until the cheese is melted and gooey, about 5 to 7 minutes. Turn the oven to broil. Broil the casserole until golden on top, 1 to 3 minutes. Do not walk away, and watch carefully to make sure the cheese does not burn.

Remove from the oven and sprinkle with fresh chives and remaining bacon. Serve hot.
