How to Make Cauliflower Cheese with Roasted Cauliflower and Cheesy Mornay Sauce Recipe
Step 1: Roast the Cauliflower
First things first, preheat your oven to 220°C (430°F). Toss the cauliflower florets gently with extra virgin olive oil, sea salt, and pepper. Spread them out on a large baking tray so they roast rather than steam. Pop them in the oven for 20 minutes without turning—this ensures some gorgeous caramelized edges while keeping them just a little firm inside. The roasting adds a sweet, nutty dimension that makes this dish unforgettable.
Step 2: Prepare the Cheesy Mornay Sauce
Reduce the oven temperature to 180°C (350°F) now. While it cools slightly, heat the milk and cream until hot (not boiling). In a large saucepan, melt unsalted butter over medium heat, then sprinkle in the flour. Stir constantly for about 3 minutes to cook off the raw flour taste, creating your roux. Slowly pour in half the hot milk mixture while whisking vigorously, allowing the sauce to thicken beautifully. Add the remaining milk, stir for another minute, and you’ll have a luscious base ready to transform into a dreamy cheese sauce.
Step 3: Add the Cheese and Seasonings
Turn off the heat but keep the sauce on the stove to maintain warmth. Stir in the kosher salt, freshly grated nutmeg, and both the grated Red Leicester and Gruyère cheeses. Mix until fully melted and the sauce thickens into that irresistible Mornay texture—creamy and cheesy with a subtle bite. This sauce is the heart and soul of your Cauliflower Cheese with Roasted Cauliflower and Cheesy Mornay Sauce Recipe.
Step 4: Combine Cauliflower with Sauce and Bake
Gently fold the roasted cauliflower into the cheese sauce, making sure each floret is beautifully coated. Transfer the mixture to a 2-liter (2-quart) baking dish, smoothing the top. Now sprinkle over extra Gruyère and Red Leicester cheese—this cheesy topping will melt and brown perfectly in the oven, adding that ultimate crust you crave.
Step 5: Bake to Golden Perfection
Slide the dish into the oven at 180°C (350°F) and bake for 30 minutes. Keep an eye out for bubbling cheese and a gorgeous golden crust that signals this dish is ready. Once out, let it rest for 5 minutes to thicken slightly before serving. This makes for a warm, comforting plate that truly celebrates every element of this Cauliflower Cheese with Roasted Cauliflower and Cheesy Mornay Sauce Recipe.

Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making it a fabulous make-ahead dish.
Freezing
You can freeze this cauliflower cheese, but be mindful that the texture of the sauce might change slightly. Transfer portions to freezer-safe boxes and freeze for up to 2 months. Thaw in the fridge overnight before reheating.
Reheating
To reheat, cover loosely with foil and warm in a 180°C (350°F) oven until heated through and bubbly. This helps preserve the golden crust and creamy sauce without drying it out.
FAQs
Can I use different types of cheese in this recipe?
Absolutely! Red Leicester and Gruyère are traditional choices for their melting qualities and flavor, but you can swap with cheddar, mozzarella, or even a bit of Parmesan for a sharper bite. Just keep a balance between creamy melt and flavor intensity.
Is this recipe suitable for vegetarians?

Yes, you can make the Mornay sauce a few hours before, but it’s best to add the cheese just before combining with cauliflower and baking to keep the sauce silky smooth.

Ingredients
Cauliflower
- 1kg / 2 lb cauliflower florets (from 1 very large, 1 ½ medium, or 2 small heads)
- 2 tbsp extra virgin olive oil
- ½ tsp sea salt
- ⅛ tsp pepper
Cheese Sauce (Mornay)
- 60g / 4 tablespoon unsalted butter
- 3½ tbsp plain / all-purpose flour
- 1 cup milk (full fat recommended)
- 1 cup cream (or additional milk)
- ½ tsp cooking salt (kosher salt)
- ¼ tsp freshly grated nutmeg powder
- 1 cup Red Leicester cheese (or cheddar), grated
- ½ cup Gruyère cheese (or other melting cheese), grated
- Additional ½ cup Gruyère cheese for topping
- Additional ½ cup Red Leicester cheese for topping
Instructions
- Roast cauliflower: Preheat the oven to 220°C / 430°F (200°C fan). Toss cauliflower florets with olive oil, sea salt, and pepper, then spread evenly on a large baking tray. Roast for 20 minutes without turning until the florets are slightly firm but have some color. Remove from the oven.
- Lower oven temperature: Reduce the oven temperature to 180°C / 350°F in preparation for baking the dish later.
- Heat milk and cream: Warm the milk and cream together until they are hot, either on the stovetop or in a microwave.
- Prepare roux: Melt the unsalted butter in a large saucepan over medium heat. Add the flour and cook, stirring regularly, for 3 minutes to create a roux without browning it.
- Add milk to roux: Pour in half of the hot milk mixture gradually while stirring continuously. Once the mixture thickens, add the remaining milk and stir for an additional minute on the heat. The sauce should be thick enough to coat the back of a wooden spoon.
- Add flavorings and cheese: Turn off the heat but keep the pot on the warmed stove. Stir in cooking salt, freshly grated nutmeg, Red Leicester cheese, and Gruyère cheese until the sauce thickens into a smooth, thick cheese sauce.
- Combine cauliflower and sauce: Add the roasted cauliflower florets to the cheese sauce and toss gently to coat all the florets evenly.
- Transfer to baking dish: Spoon the cauliflower and cheese mixture into a 2L / 2qt baking dish approximately 30 x 20 x 5 cm (12 x 8 x 2 inches).
- Add cheese topping: Evenly sprinkle the additional grated Gruyère cheese followed by the grated Red Leicester cheese over the top of the cauliflower mixture.
- Bake: Bake in the preheated oven at 180°C / 350°F for 30 minutes until the cheese topping is melted, bubbly, and golden brown.
- Serve: Optionally sprinkle with fresh parsley for garnish. Allow the dish to stand for 5 minutes before serving to set slightly and maximize flavor.
Notes
- Use full-fat milk and cream for the creamiest sauce.
- Red Leicester cheese adds sweetness and depth; cheddar can be used as a substitute.
- Gruyère is preferred for melting and flavor but any good melting cheese can be substituted.
- Do not turn cauliflower while roasting to maintain some firmness and color.
- Allow the baked dish to rest before serving to avoid burns and improve texture.
