- Cauliflower florets: The star of the dish, offering a tender yet slightly firm texture that soaks up the sauce beautifully.
- Butter: For starting your roux, ensuring a smooth, velvety sauce with depth.

- Whole milk: Provides richness and a smooth base for the sauce; half-and-half is great if you want extra decadence.
- Heavy cream (optional): Boosts richness for a truly indulgent sauce.
- Dijon mustard: Adds a gentle tang and complexity that balances the cheese’s creaminess.
- Garlic powder (optional): Infuses subtle warmth and depth without overpowering the dish.
- Salt and black pepper: Essential seasonings that elevate all the flavors perfectly.
- Ground nutmeg (optional): A pinch brings a lovely aromatic note to the cheese sauce.
- Gruyère or cheddar cheese: The heart of the gratin’s rich, melty, and savory appeal—choose your favorite or mix them for complexity.
- Parmesan cheese: Sprinkled on top for an irresistible golden crust with a savory bite.
- Breadcrumbs (optional): For an extra crispy texture that contrasts beautifully with the creamy interior.
- Fresh parsley: Adds a fresh burst of color and flavor as a finishing touch.
How to Make Cauliflower Gratin Recipe
Step 1: Preheat the Oven
Start by setting your oven to 375°F (190°C) and greasing your baking dish. This preheating ensures that once everything is assembled, your gratin bakes evenly and develops that perfect golden top without sticking.
Step 2: Cook the Cauliflower
Boil your cauliflower florets in salted water until they are just tender yet retain a slight firmness. This al dente texture ensures that the florets hold their shape and bite after baking, giving your gratin an appealing texture.
Step 3: Make the Cheese Sauce
Creating a smooth cheese sauce is where the magic happens. Melt butter and whisk in the flour to make a roux, then gradually add milk (and cream if using). Stir until thickened, then add Dijon mustard, spices, and most of your shredded cheese. This sauce is creamy, flavorful, and melts perfectly onto the cauliflower.
Step 4: Assemble the Gratin
Arrange the cooked cauliflower in your baking dish, then pour the cheese sauce evenly over the top to coat every floret. Sprinkle the remaining cheese, Parmesan, and breadcrumbs if you like a crunchy topping. This layering ensures each bite is packed with cheesy goodness and texture.
Step 5: Bake the Gratin
Bake for 25 to 30 minutes until the gratin is bubbling and the top turns a gorgeous golden brown. For an extra crispy top that adds a bit of drama and crunch, broil the last few minutes—but watch it carefully to prevent burning.
Step 6: Serve Warm and Enjoy
Let your cauliflower gratin cool just a bit before serving, then sprinkle fresh parsley on top. This final touch brightens the richness and makes every plate look as delightful as it tastes.
How to Serve Cauliflower Gratin Recipe
Garnishes
Fresh parsley is the classic choice for a reason—it adds a pop of vibrant color and a fresh, herbaceous note that contrasts with the rich cheese sauce. You might also try a sprinkle of smoked paprika for a subtle smoky twist or thinly sliced chives for a delicate onion touch.
Side Dishes
Cauliflower gratin pairs wonderfully with roasted meats, such as chicken or beef, and even fish. For a lighter meal, serve it alongside a crisp green salad or steamed greens to balance the creaminess. It also makes an excellent vegetarian main when served with crusty bread or a grain like quinoa.
Creative Ways to Present
If you want to impress your guests, try serving individual portions in small ramekins or cast iron skillets. Layer the gratin with other vegetables like thinly sliced potatoes or leeks to add complexity and a stunning layered effect. You can even add crispy bacon or toasted nuts on top for added texture and flavor contrast.
Make Ahead and Storage
Storing Leftovers
Let your leftovers cool completely, then cover and refrigerate. They will keep well for up to 3 days, and the flavors tend to meld nicely overnight, making it a great make-ahead option for busy weeknights.
Freezing
Cauliflower gratin freezes beautifully. After cooling, transfer portions (or the whole dish) to airtight containers or freezer bags. Freeze for up to 2 months. When ready to eat, thaw in the fridge overnight before reheating gently.
Reheating
Reheat your gratin in the oven at 350°F (175°C) until warmed through and bubbling, usually about 20 minutes, to preserve the crispy top. Microwaving works too but may soften the topping, so oven reheating is ideal for maintaining that wonderful texture.
FAQs
Can I use a different type of cheese in this Cauliflower Gratin Recipe?
Absolutely! While Gruyère and cheddar are traditional, you can experiment with cheeses like mozzarella, fontina, or even a sharper blue cheese for a different flavor profile. Just choose cheeses that melt well.
Is it possible to make this Cauliflower Gratin Recipe dairy-free?
Yes, by substituting butter with plant-based margarine, using a non-dairy milk like almond or oat, and selecting a vegan cheese alternative, you can enjoy a dairy-free version. The texture and flavor will be slightly different but still delicious.
How can I make the gratin extra crispy on top?
Using breadcrumbs mixed with a little melted butter sprinkled on top before baking makes for a crunchy crust. Broiling the last 2-3 minutes intensifies the crispiness but watch it carefully to avoid burning.
Can I prepare the gratin sauce ahead of time?
You can make the cheese sauce a day in advance and refrigerate it. Bring it back to a gentle simmer with a splash of milk before assembling the gratin to refresh the sauce’s smooth texture.
Is there a gluten-free option for this Cauliflower Gratin Recipe?
Yes! Swap the all-purpose flour for a gluten-free flour blend or cornstarch to thicken the sauce. Also, use gluten-free breadcrumbs if you want that crunchy topping. Everything else remains the same.

Ingredients
Cauliflower
- 1 large head of cauliflower, cut into florets
Cheese Sauce
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 1/2 cups whole milk (or half-and-half for extra creaminess)
- 1/2 cup heavy cream (optional, for richer sauce)
- 1/2 teaspoon Dijon mustard
- 1/2 teaspoon garlic powder (optional)
- Salt and freshly ground black pepper, to taste
- 1/2 teaspoon ground nutmeg (optional)
- 1 1/2 cups shredded Gruyère or cheddar cheese (or a mix)
- 1/4 cup grated Parmesan cheese
Topping
- 1/4 cup breadcrumbs (optional, for a crunchy topping)
- Fresh parsley, chopped (for garnish)
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or an equivalent-sized gratin dish to prevent sticking and ensure even cooking.
- Cook the Cauliflower: Bring a large pot of salted water to a boil. Add the cauliflower florets and cook for 5-7 minutes until they are just tender but still retain a slight firmness (al dente). Drain the florets thoroughly and set them aside.
- Make the Cheese Sauce: In a medium saucepan over medium heat, melt the butter. Stir in the flour and cook, stirring constantly, for about 2 minutes to form a roux. Gradually whisk in the milk and heavy cream (if using), whisking continuously until the sauce is smooth and begins to thicken, about 3-4 minutes. Add the Dijon mustard, garlic powder (if using), salt, pepper, and nutmeg to the sauce. Stir in 1 cup of the shredded Gruyère or cheddar cheese until melted and smooth. Remove the sauce from heat.
- Assemble the Gratin: Place the cooked and drained cauliflower florets evenly into the prepared baking dish. Pour the cheese sauce over the cauliflower, ensuring all pieces are well coated. Sprinkle the remaining 1/2 cup of shredded cheese along with the Parmesan cheese evenly over the top. If desired, sprinkle breadcrumbs over the cheese layer for added crunch.
- Bake the Gratin: Bake in the preheated oven for 25-30 minutes until the top is golden brown and the sauce is bubbling. For an extra crispy topping, you can broil the gratin for 2-3 minutes at the end, watching closely to avoid burning.
- Serve: Remove the gratin from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley before serving warm to enjoy.
Notes
- For a richer sauce, use half-and-half instead of milk, and add the optional heavy cream.
- Breadcrumbs are optional but add a lovely crunchy topping; omit for a softer texture.
- You can substitute Gruyère with cheddar or a mix depending on your preference.
- Be careful when broiling; it only takes a couple of minutes to brown and can burn quickly.
- This dish can be prepared a day ahead and baked just before serving.
- To make this dish gluten-free, use gluten-free flour and breadcrumbs.
