Full Recipe

Ingredients

• 1 large head of cauliflower (about 1 kg / 2.2 lbs), cut into florets

• 2 tablespoons butter

• 2 tablespoons all-purpose flour

• 2 cups (500 ml) milk (whole or 2%)

• 1 cup (240 ml) heavy cream

• 1 cup (100 g) grated cheddar cheese

• ½ cup (50 g) grated mozzarella cheese

• ½ cup (50 g) grated Parmesan cheese

• 1 teaspoon Dijon mustard

• 1 clove garlic, minced

• Salt and black pepper, to taste

• Pinch of nutmeg (optional, for added depth)

• ½ cup breadcrumbs (optional topping)

• 1 tablespoon melted butter (for topping)

• Fresh parsley, chopped (for garnish)

Cooking Directions

1. Prepare the Cauliflower:
   Begin by preheating your oven to 190°C (375°F). Cut the cauliflower into even-sized florets and rinse them thoroughly. Bring a large pot of salted water to a boil and add the cauliflower. Boil for about 5 minutes or until slightly tender but still firm. Drain well and set aside to cool slightly.

2. Make the Creamy Cheese Sauce:
   In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add the minced garlic and sauté for 30 seconds until fragrant. Whisk in the flour and cook for 1–2 minutes to create a roux, stirring constantly to avoid lumps. Gradually add the milk while whisking continuously, then pour in the heavy cream. Continue whisking until the sauce thickens and becomes smooth, about 5–6 minutes.

3. Add the Cheese and Seasoning:
   Reduce the heat to low and stir in the cheddar, mozzarella, and half of the Parmesan cheese. Mix until melted and fully combined. Add the Dijon mustard, a pinch of nutmeg, and season with salt and black pepper to taste. The sauce should be creamy, smooth, and rich with flavor.

4. Combine Cauliflower and Sauce:
   Place the boiled cauliflower florets in a greased baking dish. Pour the hot cheese sauce evenly over the top, ensuring every floret is coated. Gently mix to distribute the sauce if needed.

5. Prepare the Topping:
   In a small bowl, mix the breadcrumbs with melted butter and the remaining Parmesan cheese. Sprinkle this mixture evenly over the top of the gratin. This step gives the dish a beautiful golden crust when baked.

6. Bake Until Golden and Bubbly:
   Transfer the dish to the preheated oven and bake for 25–30 minutes, or until the top is golden brown and bubbling around the edges. For extra crispiness, you can broil it for 2–3 minutes at the end.

7. Serve and Enjoy:
   Let the gratin cool slightly before serving. Garnish with fresh parsley and enjoy as a side dish or even a light main course with crusty bread.

The Origins and Inspiration Behind the Dish

Cauliflower gratin has its roots in French cuisine, where “gratin” refers to any dish topped with cheese or breadcrumbs and baked until browned. Classic French gratins often use potatoes or pasta, but cauliflower became a popular alternative for its mild flavor and ability to absorb rich sauces. Over time, this dish has evolved from a traditional Parisian side to a global comfort favorite, especially for those looking for low-carb or gluten-conscious options. Its inspiration lies in the simple elegance of home-cooked French food—rich in flavor, beautifully baked, and deeply satisfying.

Ingredient Spotlight

Cauliflower is the star of this dish. It’s not only delicious but also incredibly versatile and nutritious. Its subtle flavor acts as the perfect blank canvas for creamy sauces. Cheese—specifically cheddar, mozzarella, and Parmesan—adds layers of flavor: cheddar for sharpness, mozzarella for meltiness, and Parmesan for its nutty, salty depth. Milk and cream provide the luxurious texture that makes this gratin so comforting. Dijon mustard adds a gentle tang that cuts through the richness, while breadcrumbs create a satisfying crunch that contrasts the smooth interior. Every ingredient plays its part to achieve that perfect creamy-crispy balance.

Storage and Reheating Tips

Leftover cauliflower gratin stores beautifully. Once cooled, cover it tightly with foil or transfer it to an airtight container and refrigerate for up to 4 days. To reheat, place it in a preheated oven at 175°C (350°F) for about 15 minutes, or until warmed through and bubbly. If you’re in a hurry, microwave individual portions for 1–2 minutes, but for best results, the oven method keeps the topping crisp. You can also freeze the gratin before baking. Assemble it in a freezer-safe dish, cover well, and freeze for up to 2 months. When ready to serve, thaw overnight in the fridge and bake as usual.

Common Variations to Try

There are so many creative ways to make this dish your own. Try a broccoli and cauliflower mix for extra color and flavor. For a meatier version, add cooked bacon bits, diced ham, or shredded chicken before baking. If you prefer a lighter option, swap the heavy cream for half-and-half or use plant-based milk and cheese for a vegetarian or lactose-free version. You can also go bold with a spicy twist by adding chili flakes or a touch of cayenne pepper to the sauce. Or try a gourmet upgrade—a sprinkle of truffle oil or a handful of caramelized onions can make it extra special.

Pairing Recommendations

Creamy Cauliflower Gratin pairs beautifully with roasted meats like beef, chicken, or pork. It also complements fish dishes such as baked salmon or grilled cod. For a vegetarian meal, serve it alongside a crisp green salad or roasted vegetables. A chilled glass of Chardonnay or Sauvignon Blanc enhances the creamy texture and cheesy richness perfectly. For something more casual, pair it with garlic bread or a light tomato soup for a cozy meal.

Health Benefits

Don’t let the creamy sauce fool you—this dish is surprisingly nutritious. Cauliflower is rich in vitamins C, K, and B6, along with fiber and antioxidants that promote healthy digestion and reduce inflammation. Using cauliflower instead of potatoes or pasta lowers the carb content significantly, making this gratin a smart choice for those on keto or low-carb diets. The cheese adds calcium and protein, while milk and cream provide essential fats for energy. When enjoyed in moderation, this dish offers the best of both worlds: comfort and nutrition.

Conclusion

Creamy and Cheesy Cauliflower Gratin is a classic for a reason—it’s simple, satisfying, and downright delicious. The combination of tender cauliflower, velvety cheese sauce, and golden crispy topping makes it impossible to resist. Whether you’re cooking for family, friends, or just yourself, this recipe brings warmth and comfort to the table every single time.
