If you are looking for a cozy way to make cauliflower feel a little more exciting, this Creamy Baked Cauliflower with Mozzarella and Tomatoes is a wonderful place to start. Roasted cauliflower is combined with a creamy tomato sauce, Parmesan, juicy grape tomatoes, and plenty of melted mozzarella for a dish that is warm, flavorful, and wonderfully comforting.
The cauliflower gets lightly caramelized in the oven before being folded into the creamy sauce, giving it much more flavor than simply boiling it. Once everything is baked together, the cheese becomes golden and bubbly while the tomatoes soften and add little bursts of freshness. It is an easy side dish that can also be served as a light vegetarian meal.
Flavor & Texture Highlights
The roasted cauliflower develops lightly browned edges and a tender texture, while the creamy tomato sauce adds richness and a gentle tang. Parmesan brings a savory depth, and melted mozzarella creates a deliciously cheesy finish.
Fresh grape tomatoes add sweetness and juiciness, while basil brightens the dish with a fresh herb flavor. If you enjoy a little heat, a pinch of red pepper flakes adds just the right amount of warmth.

Why You’ll Love This Recipe
This baked cauliflower is an easy way to turn a simple vegetable into something that feels special. Roasting the cauliflower first gives it a wonderful depth of flavor, while the creamy tomato sauce and melted cheese make every bite rich and satisfying.
It is also easy to prepare ahead of time and works beautifully alongside chicken, beef, fish, or pasta. With colorful tomatoes, fresh basil, and a golden cheesy top, it is just as lovely to serve for a family dinner as it is for a weekend gathering.
What You’ll Need to Make This Recipe
Cauliflower: Choose a medium head of fresh cauliflower and cut it into evenly sized florets. Roasting brings out its natural sweetness and gives the edges a delicious caramelized flavor.
Tomato sauce and tomato paste: These create the flavorful base of the creamy sauce. The tomato paste adds extra richness and concentrated tomato flavor.
Heavy cream: A little heavy cream softens the acidity of the tomato sauce and creates a smooth, luxurious texture.
Parmesan cheese: Parmesan adds salty, savory depth to the sauce and pairs beautifully with the mozzarella.
Mozzarella: Shredded mozzarella gives the casserole its wonderfully gooey, bubbly topping. Dividing it between the filling and the top helps create cheesy flavor throughout the dish.
Grape tomatoes: Halved grape tomatoes add color, sweetness, and juicy little bites throughout the casserole.
Fresh basil: Fresh basil adds a bright herbal finish that balances the creamy sauce and cheese.
Seasonings: Sea salt and black pepper keep the flavors balanced, while red pepper flakes are optional if you want a little extra heat.

How to Make Creamy Baked Cauliflower with Mozzarella and Tomatoes Step by Step
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 425°F (220°C) and position a rack in the middle. Lightly grease a medium baking dish with olive oil and set it aside so it is ready when the cauliflower mixture is assembled.
Step 2: Roast the Cauliflower
Spread the cauliflower florets evenly on a baking sheet. Drizzle with 1 tablespoon of olive oil and season with coarse salt and pepper. Roast for about 30 minutes, turning the florets once halfway through cooking, until they are tender and lightly caramelized around the edges.
Step 3: Make the Creamy Tomato Sauce
While the cauliflower is roasting, place the tomato sauce and tomato paste in a large saucepan over low heat. Warm the mixture gently, then stir in the heavy cream, Parmesan cheese, red pepper flakes if using, salt, and black pepper. Once everything is smooth and warmed through, remove the saucepan from the heat.
Step 4: Combine the Cauliflower and Sauce
Add the roasted cauliflower to the creamy tomato mixture and gently stir until the florets are evenly coated. Fold in half of the shredded mozzarella, half of the halved grape tomatoes, and a small amount of the chopped fresh basil.
Step 5: Transfer to the Baking Dish
Spoon the cauliflower mixture into the prepared baking dish and spread it into an even layer. Scatter the remaining mozzarella and grape tomatoes over the top, making sure the cheese is distributed well across the surface.
Step 6: Bake Until Bubbly
Reduce the oven temperature to 350°F (175°C). Bake the casserole for about 30 minutes, until it is hot throughout and the cheese is melted and bubbling.
Step 7: Brown the Top
For a beautifully golden finish, switch the oven to broil and broil the casserole for 1 to 2 minutes. Watch it closely during this step because the cheese can brown very quickly.
Step 8: Rest and Garnish
Let the casserole rest for about 5 minutes before serving. Sprinkle the remaining fresh basil over the top just before bringing it to the table. The short resting time allows the creamy sauce to settle slightly while keeping the dish warm and delicious.
Expert Tips
- Cut the cauliflower into similarly sized florets so they roast evenly.
- Do not overcrowd the baking sheet. Giving the cauliflower enough space helps the edges caramelize instead of simply steaming.
- Turn the cauliflower halfway through roasting for more even browning.
- Warm the tomato sauce gently rather than cooking it aggressively after adding the cream.
- Use freshly shredded mozzarella when possible for a smooth, gooey melt.
- Keep a close eye on the casserole while broiling because the cheese can go from golden to burnt quickly.
- Let the casserole rest for a few minutes before serving so the sauce can settle slightly.
How to Store and Reheat It
Allow any leftovers to cool before transferring them to an airtight container. Store them in the refrigerator for up to 3 to 4 days.
To reheat, place an individual portion in the microwave until warmed through, or cover the casserole with foil and reheat it in a 350°F (175°C) oven until hot. If you want to refresh the cheesy top, remove the foil during the final few minutes.
What to Serve With
This creamy baked cauliflower makes a wonderful side dish for roasted chicken, grilled chicken, steak, pork, or baked fish. The creamy tomato sauce also makes it a natural partner for simple pasta dishes.
For a lighter vegetarian meal, serve it with a crisp green salad and some crusty bread for soaking up the creamy tomato sauce.
Frequently Asked Questions
Can I use frozen cauliflower?
Fresh cauliflower is ideal for this recipe because it roasts beautifully, but frozen cauliflower can work in a pinch. Thaw it first and drain it very well to remove excess moisture before roasting.
Can I make this casserole ahead of time?
Yes. You can prepare the cauliflower and sauce, assemble the casserole, cover it, and refrigerate it until you are ready to bake. Allow some extra time for the chilled casserole to heat through.
Can I use another type of cheese?
Yes. Monterey Jack, provolone, fontina, or a mild Italian cheese blend can work well. Mozzarella provides the classic stretchy texture, while Parmesan adds savory flavor.
Can I make this dish spicy?
Absolutely. Add the suggested red pepper flakes for a gentle kick, or increase the amount if you prefer more heat. You can also add a pinch of crushed chili flakes to the sauce.
Why roast the cauliflower before baking it in the sauce?
Roasting removes some moisture and creates caramelized edges, giving the cauliflower a deeper, richer flavor and better texture than simply cooking it directly in the sauce.
Can I use regular tomatoes instead of grape tomatoes?
Yes. Cherry tomatoes are an easy substitute. If using larger tomatoes, cut them into small pieces so they cook evenly with the casserole.
