How to Make Cheesy Cauliflower Au Gratin (Print-Friendly Version)

Step 1: Prepare Your Oven and Baking Dish

Begin by preheating your oven to 190°C so it’s ready to go as soon as your dish is assembled. Grease a 33×23 cm baking dish with butter or non-stick spray to ensure nothing sticks and to promote that perfect golden crust on top.

Step 2: Blanch the Cauliflower

Boil a large pot of salted water to bring out the cauliflower’s natural flavor. Add the florets and blanch them for 5 minutes until they just start to get tender but still hold their shape. This step prevents the cauliflower from becoming soggy during baking. Drain well and set aside to avoid a watery sauce later.

Step 3: Make the Cheese Sauce Base

In a saucepan over medium heat, melt the butter and whisk in the flour. Cook this roux for 1 to 2 minutes until it turns pale and fragrant—this cooks out the raw flour taste and sets the foundation for a silky sauce.

Step 4: Whisk in the Cream and Seasonings

Gradually add the heavy cream while stirring constantly so the sauce thickens evenly over 3 to 4 minutes. Then mix in garlic powder, onion powder, salt, and black pepper. This combination layers in flavor that perfectly complements the cheese.

Step 5: Melt in the Cheeses

Remove the saucepan from heat and stir in half the cheddar and half the Parmesan until completely melted and smooth. This rich sauce will coat every bit of cauliflower beautifully.

Step 6: Assemble the Dish

Arrange the blanched cauliflower evenly in your prepared baking dish. Pour the cheese sauce over the florets, ensuring every piece is generously coated for maximum cheesy goodness.

Step 7: Top with Remaining Cheese

Sprinkle the rest of the cheddar and Parmesan evenly over the top. This step is what creates that irresistible golden crust once it’s baked.

Step 8: Bake to Perfection

Place the dish in the centre of the oven and bake for 25 to 30 minutes. You want that top layer to bubble and turn a gorgeous golden color signaling it’s ready to enjoy.

Step 9: Garnish and Cool Slightly

Once out of the oven, allow it to cool just a bit before scattering fresh chopped parsley across the top. The herb adds a fresh brightness to balance the richness and makes your Cheesy Cauliflower Au Gratin (Print-Friendly Version) look as fantastic as it tastes.

How to Serve Cheesy Cauliflower Au Gratin (Print-Friendly Version)

Garnishes

Fresh parsley is a classic garnish, but feel free to add finely chopped chives or a sprinkle of paprika for a subtle smoky touch and vibrant pop of color. These little finishing touches make every bite as visually delightful as it is flavorful.

Side Dishes

This dish pairs wonderfully with a variety of mains. Try it alongside a juicy roasted chicken, tender pork chops, or even a hearty steak. Its creamy texture and rich flavor can brighten up any protein or grain on your plate.

Creative Ways to Present

If you want to fancy things up, serve smaller portions in individual ramekins for dinner parties. Top with breadcrumbs before baking for extra crunch, or mix in some crispy bacon or sautéed mushrooms for added layers of flavor. There’s no wrong way to make this dish your own.

Make Ahead and Storage

Storing Leftovers

Place leftover Cheesy Cauliflower Au Gratin in an airtight container and refrigerate for up to 3 days. The flavors meld beautifully overnight, making it an excellent dish to enjoy the next day.

Freezing

You can freeze this dish before baking. Cover tightly with foil and wrap with plastic wrap to prevent freezer burn. It will keep well for up to 2 months. To bake, thaw overnight in the fridge and then proceed with baking as usual.

Reheating

Reheat leftovers in a preheated oven at 175°C for about 15 to 20 minutes or until bubbly and warmed through. Microwaving works too but risks losing the crispy top, so oven reheating is best to maintain that wonderful texture.

FAQs

Can I use another type of cheese for this recipe?

Absolutely! While sharp cheddar and Parmesan offer the perfect balance of creaminess and tang, you can experiment with Gruyère, Mozzarella, or even a spicy Pepper Jack for a twist in flavor. Just make sure the cheese melts well.

Is it possible to make this dish dairy-free?

Yes, by substituting the butter with olive oil or a vegan butter substitute, using coconut cream or a plant-based cream alternative, and choosing vegan cheeses, you can make a dairy-free version. The flavor will differ slightly but still be delicious.

Why do I need to blanch the cauliflower first?

Blanching softens the cauliflower just enough to prevent it from being raw and crunchy after baking while keeping its shape. It also helps reduce excess moisture which can make the gratin watery.

Can I add breadcrumbs to the topping?

Definitely! Sprinkling breadcrumbs mixed with a little melted butter on top before baking adds a lovely crunchy texture that contrasts nicely with the creamy interior.

What can I do if my sauce is too thick or thin?

If your cheese sauce becomes too thick, gently whisk in a splash of cream or milk until you reach the desired consistency. For a thin sauce, cook a little longer over low heat to reduce and thicken it up.
