• 120ml (1/2 cup) unsweetened almond milk
• 100g (3.5oz / 1 cup) freshly grated Parmesan cheese, divided
• 60g (2oz / 1/2 cup) sharp cheddar cheese, grated
• 3 cloves garlic, minced
• 30g (2 tbsp) grass-fed butter
• 15g (1 tbsp) cream cheese, softened
• 5ml (1 tsp) fresh thyme leaves
• 2.5ml (1/2 tsp) dried rosemary
• 2.5ml (1/2 tsp) sea salt
• 1.25ml (1/4 tsp) black pepper
• 1.25ml (1/4 tsp) nutmeg
• 30g (1oz / 1/4 cup) pork rinds, crushed (optional, for topping)
• 15ml (1 tbsp) fresh parsley, chopped for garnish

Instructions

1. Step 1: Preheat your oven to 190°C (375°F). Grease a 23cm (9-inch) baking dish with butter.
2. Step 2: Bring a large pot of salted water to boil. Add cauliflower florets and cook for 8-10 minutes until fork-tender but still firm. Drain thoroughly and pat dry with paper towels.
3. Step 3: In a large saucepan over medium heat, melt the butter. Add minced garlic and sauté for 1-2 minutes until fragrant, being careful not to brown.
4. Step 4: Slowly whisk in the heavy cream and almond milk. Add the softened cream cheese and whisk until completely smooth and combined.
5. Step 5: Add thyme, rosemary, salt, pepper, and nutmeg to the cream mixture. Simmer gently for 3-4 minutes, stirring occasionally.
6. Step 6: Remove from heat and gradually whisk in 75g (2.5oz) of the Parmesan cheese and all the cheddar cheese until melted and smooth.
7. Step 7: Arrange the cooked cauliflower florets in the prepared baking dish in an even layer.
8. Step 8: Pour the cheese sauce evenly over the cauliflower, ensuring all florets are well coated. Gently shake the dish to distribute the sauce.
9. Step 9: Sprinkle the remaining 25g (0.5oz) Parmesan cheese over the top, followed by the crushed pork rinds if using.
10. Step 10: Bake for 20-25 minutes until the top is golden brown and the sauce is bubbling around the edges.
11. Step 11: Remove from oven and let rest for 5 minutes to allow the sauce to set slightly.
12. Step 12: Garnish with fresh chopped parsley and serve immediately while hot and creamy.

Chef’s Tips

• Ensure cauliflower is thoroughly drained and patted dry before baking to prevent a watery gratin. Excess moisture is the enemy of creamy texture.
• Use freshly grated Parmesan cheese rather than pre-grated for the best melting properties and richer flavor. The pre-grated versions contain anti-caking agents that can affect texture.
• For extra richness, substitute half the heavy cream with full-fat coconut cream, which adds a subtle sweetness that complements the savory cheese beautifully.

Health Benefits

This nutrient-dense gratin provides powerful anti-inflammatory benefits from garlic and herbs while delivering healthy saturated fats that support hormone production and brain health. Cauliflower is rich in choline for cognitive function, vitamin K for bone health, and sulforaphane compounds that support detoxification. The high-fat, low-carb profile helps maintain stable blood sugar levels and promotes ketosis for sustained energy and mental clarity.

Storage Instructions

Store leftovers covered in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1-2 minutes or reheat the entire dish in a 160°C (325°F) oven for 15-20 minutes until heated through. The gratin can be assembled up to 24 hours ahead and refrigerated before baking – just add 5-10 extra minutes to the cooking time.
