How to Make Cauliflower Casserole with Step-by-Step Instructions

A complete printable recipe and the measurements in both US customary and metric are available in the recipe card below.

Preparing Your Cauliflower

Let’s start with the star of our dish, the cauliflower! Begin by preheating your oven to 365°F/180ºC.

While it’s warming up, cut your fresh cauliflower into bite-sized florets. Place them on a rimmed baking sheet, and make sure they have a bit of space between each piece to roast evenly.

Brush them generously with olive oil, and sprinkle paprika, salt, and pepper for that extra kick of flavor. Roast the cauliflower in your preheated oven for about 20 minutes, or until it starts to brown and soften and is fork tender. 

Crafting the Creamy Sauce

While your cauliflower is roasting, let’s get started on that luscious white sauce that will smother our florets in creamy goodness.

In a pot, melt some butter and whisk in flour to create a smooth roux. Gradually add milk, continuing to whisk until the mixture is smooth and starts to thicken. Season with salt and black pepper to taste.

Next, mix panko breadcrumbs with melted butter, grated parmesan cheese, paprika, salt, and pepper in a large bowl.

Assembling the Casserole

Once your cauliflower is roasted and your white sauce is velvety smooth, it’s time to assemble the casserole.

Make sure your roasted cauliflower is evenly spread across the bottom of your baking dish. Pour over your sauce so that all the florets are generously coated.

Then sprinkle the breadcrumb mixture evenly over the top of your sauced cauliflower.

Recipe Notes and Expert Tips

• Cauliflower: Selecting a fresh cauliflower head is key to a delightful casserole. Look for a cauliflower that’s firm with tightly packed florets and a vibrant white color. The leaves should be fresh and vibrant, indicating a healthy, fresh cauliflower. Remember, the fresher the cauliflower, the sweeter and more flavorful your casserole will be. However, if fresh cauliflower is not available, frozen cauliflower florets can also do the trick! Just be sure to thaw and pat them dry to avoid extra moisture in your casserole.
• Perfectly Crispy Top Layer: Achieving a crispy, golden-brown top is crucial for that delightful textural contrast in your cauliflower casserole. Using panko breadcrumbs will give you a lighter, airier crunch compared to regular breadcrumbs. Make sure your oven is fully preheated before baking the casserole. You can even try using the broiler for the last few minutes to really crisp up the top. But keep a close eye on it to avoid burning!
• Cheese: While parmesan cheese offers a lovely, nutty flavor to the casserole, don’t be afraid to experiment with other cheeses. A mix of sharp cheddar cheese and Monterey jack cheese can provide a beautiful melty texture and a rich flavor profile. Feel free to play around with different cheese combinations to find your perfect match!
• Sauce: You can transform your white sauce into a cheese sauce by mixing in some shredded cheese like cheddar or mozzarella. To make it extra rich and creamy, try mixing in some cream cheese or sour cream.
• Gluten-Free or Keto Cauliflower Casserole: For those on a keto diet or looking for a gluten-free option, this cauliflower casserole can easily be adapted. Replace the flour in the sauce with a keto-friendly thickener like xanthan gum or plain gluten-free flour. For the panko breadcrumbs, you can either use gluten-free breadcrumbs or try some toasted almond flour for that crunch.
• Variations: For a change in taste, try adding garlic powder or onion powder to your sauce for extra flavor. Diced vegan ham, broccoli, brussels sprouts, or sautéed mushrooms can also be wonderful additions to the casserole, making it heartier. Just roast the additional veggies along with the cauliflower to ensure tenderness. Have cheesy loaded cauliflower casserole by adding veggie crispy bacon for a real treat.

How to Store Leftover Cauliflower Casserole

The great thing about this cheesy cauliflower casserole recipe, is that it keeps well, so you can enjoy it at a later date.

Keeping it Fresh in the Fridge

To store leftovers in the refrigerator, allow the casserole to cool to room temperature.

Place it in an airtight container or cover the casserole dish tightly with plastic wrap or aluminum foil. Properly stored, your cheesy cauliflower casserole will maintain its best quality for 3 to 5 days in the fridge.

When you’re ready to enjoy it again, you can reheat it in the oven or microwave until it’s heated through and the cheese is bubbly.

Freezing for Longer Storage

For longer storage, the cauliflower casserole can also be frozen. Once cooled, portion the casserole into serving sizes and place them in airtight containers or heavy-duty freezer bags.

Squeeze out as much air as possible to prevent freezer burn and keep your casserole tasting fresh. Properly stored, it will maintain its best quality for about 2 to 3 months.

When you’re ready to enjoy your frozen casserole, thaw it in the refrigerator overnight and then reheat in the oven or microwave.

Reheating to Perfection

When it comes to reheating your cauliflower casserole, a few minutes in the oven or microwave will bring it back to its original creamy, cheesy glory.

If using the oven, preheat it to 350°F (175°C) and bake the casserole until it’s hot and bubbly. This should take about 15-20 minutes.

For the microwave, place your portion on a microwave-safe plate and heat it on high for 2-3 minutes. Check and stir it halfway through to ensure even heating.

A Note on Texture

Keep in mind that while the flavors will remain delightful, the texture of the cauliflower may change slightly upon reheating, becoming a bit softer.

The crispy topping might also lose some of its crunch, especially if reheated in the microwave. But no worries, a quick broil in the oven can bring back some of that desired crispiness to your leftover cauliflower casserole!

What to Serve with Cauliflower Casserole

It’s no surprise that this tasty casserole pairs with all kinds of different dishes, here are some of our suggestions.

A Hearty Main Course

Cauliflower casserole, with its creamy, cheesy goodness, pairs wonderfully with a variety of main courses.

Try serving it with an Air Fryer Vegan Ham or a delicious Nut Roast to create a hearty, satisfying meal. If you’re in the mood for something a bit lighter, vegetarian stuffed peppers would also pair beautifully.

Vibrant Vegetables

While the cauliflower casserole is a star on its own, pairing it with vibrant vegetables can elevate your meal to new heights. A side of air fryer carrots or a 7-layer salad with its creamy dressing pairs beautifully.

Air fryer green beans, roasted Brussels sprouts, or a colorful medley of roasted vegetables can also provide a delightful contrast, both in flavors and colors. Your plate will be visually appealing and equally delicious.

A Light, Refreshing Side

To balance the rich, creamy nature of the cauliflower casserole, consider serving it with a light, refreshing side.

A cucumber salad or a crisp coleslaw with a light, tangy dressing can provide a refreshing change to the richness of the casserole.

Alternatively, a simple Caprese salad sprinkled with fresh basil and a drizzle of balsamic glaze can offer a burst of freshness.

A Hearty Bread

Try serving your creamy cauliflower casserole with a side of French bread, freshly baked flatbread, or rustic sourdough.

We love using the bread to scoop up any leftover sauce. Every drop of deliciousness is savored!
