Instructions:
- Prepare the cauliflower: Preheat your oven to 375°F (190°C). Steam or blanch the cauliflower florets until they are tender but still firm, about 5-7 minutes. Drain and set aside.
- Make the creamy sauce: In a medium saucepan, heat the olive oil or butter over medium heat. Add the minced garlic and cook for about 1 minute until fragrant. Stir in the flour and cook for another minute to create a roux (this will help thicken the sauce).
- Add the milk: Gradually pour in the almond milk while whisking to avoid lumps. Continue to whisk until the sauce thickens, about 3-4 minutes. Season with salt, pepper, onion powder, and nutmeg (if using). Once the sauce is thick and creamy, remove from heat.
- Combine the sauce and cauliflower: Add the steamed cauliflower florets into the sauce, stirring gently to coat each piece with the creamy sauce.
- Assemble the gratin: Transfer the cauliflower and sauce mixture into a greased baking dish. Sprinkle the grated cheddar cheese and Parmesan on top, making sure to cover the entire surface.
- Bake: Place the dish in the oven and bake for 20-25 minutes, or until the top is golden and bubbly.
- Garnish and serve: Once out of the oven, sprinkle with freshly chopped parsley and serve warm.
