Directions

<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Preheat your oven to 200°C (180°C fan). This high temperature will help to remove excess moisture from the cauliflower, preventing a watery final dish. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> Place the cauliflower florets on a baking tray, drizzle with olive oil, and sprinkle with garlic powder, salt, and pepper. Toss until evenly coated. Spreading the florets in a single layer allows them to roast rather than steam, creating better flavor through caramelization. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> Roast the cauliflower for 20 minutes until just tender and beginning to brown at the edges. You want the cauliflower slightly underdone as it will continue cooking in the cheese sauce. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> While the cauliflower is roasting, prepare your cheese sauce. In a medium saucepan over medium-low heat, warm the double cream until it begins to simmer gently. The slow heating prevents the cream from separating. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Add the cream cheese and whisk continuously until completely melted and smooth. The cream cheese acts as both a thickener and emulsifier, helping create a stable sauce without the need for flour. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> Reduce the heat to low and gradually add 100g of the cheddar, 50g of the mozzarella, and all of the parmesan, stirring between additions until each is fully melted. Adding cheese gradually prevents clumping and ensures a smooth, velvety texture. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Stir in the mustard powder and nutmeg, which enhance the cheese flavor without adding carbs. Season with salt and pepper to taste, remembering that the cheeses already contribute saltiness. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Transfer the roasted cauliflower to your baking dish and pour the cheese sauce evenly over the top. Gently stir to ensure all the cauliflower is coated in the luxurious sauce. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Sprinkle the remaining cheddar and mozzarella on top, then scatter with chopped chives. The combination of cheeses creates a beautiful melt with the stretchy mozzarella providing those irresistible cheese pulls. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> Bake for 15 minutes until the cheese is melted, then switch to the grill (broiler) setting and cook for a further 2-3 minutes until golden and bubbling. Watch carefully during this step to achieve the perfect golden crust without burning. </li> <li class="MethodStepper"> <h4 class="step-title">Step 11</h4> Remove from the oven and let stand for 5 minutes before serving. This brief resting period allows the sauce to thicken slightly as it cools, resulting in a more scoopable consistency. </li> <li class="MethodStepper"> <h4 class="step-title">Step 12</h4> Garnish with additional fresh chives and serve hot as a delicious keto-friendly side dish or main course. The bake will keep well in the refrigerator for up to 3 days and can be reheated in the oven until hot throughout. </li> </ol>

Chef’s Notes

A few helpful details for making this recipe.

Can I make this cheesy cauliflower dish ahead of time?

Yes, you can prepare this dish up to 2 days ahead. Assemble completely, cover and refrigerate unbaked. When ready to serve, allow it to come to room temperature for 30 minutes, then bake as directed, adding an extra 5-10 minutes to the cooking time if still cold from the fridge.

Why is my cauliflower cheese bake watery?

Watery cauliflower bakes typically result from not removing enough moisture from the cauliflower before adding the cheese sauce. Roasting the cauliflower first (rather than boiling or steaming) and letting the finished dish rest for 5 minutes before serving helps create a thicker, creamier consistency.

What can I serve with a cheesy cauliflower bake on a keto diet?

Pair your cheesy cauliflower bake with keto-friendly options like grilled chicken, steak, or salmon for a complete meal. Add a fresh side salad with leafy greens, avocado and a high-fat dressing, or serve alongside keto garlic bread made with almond flour for the perfect low-carb feast.
