Ingredients
- 1 medium cauliflower head, cut into florets
- 3 tablespoons olive oil, divided
- Salt and freshly ground black pepper, to taste
- 4 cloves garlic, minced
- 1 cup raw cashews, soaked in hot water for 20 minutes
- 1 ½ cups unsweetened almond milk (or other plant milk)
- 2 tablespoons nutritional yeast
- 1 tablespoon fresh lemon juice
- 1 teaspoon onion powder
- ½ teaspoon smoked paprika
- 1 tablespoon vegan butter or additional olive oil
- Fresh basil and chopped parsley, for garnish
- Cooked pasta of choice (fettuccine or linguine recommended)
instructions
- Preheat the oven to 425°F (220°C). Toss cauliflower florets with 2 tablespoons olive oil, salt, and pepper. Arrange on a baking sheet in a single layer.
- Roast the cauliflower for 25 minutes or until golden brown and tender, flipping halfway through for even caramelization. This roasting step is essential to unlock the nutty, rich flavor that complements the creamy sauce.
- Drain the soaked cashews and place them in a high-speed blender with the almond milk, nutritional yeast, garlic, lemon juice, onion powder, smoked paprika, and a pinch of salt.
- Blend on high until the mixture is fully smooth and creamy, about 2-3 minutes. Add more almond milk if needed to reach a silky sauce consistency.
- Heat a medium skillet over medium heat and melt the vegan butter or warm 1 tablespoon olive oil. Pour in the cashew Alfredo sauce and gently warm, stirring constantly until it thickens slightly, about 5 minutes.
- Add the roasted cauliflower to the skillet and toss gently to coat with the sauce, allowing the florets to soak in the flavors for 2-3 minutes.
- combine the sauce and cauliflower mixture with your cooked pasta, tossing thoroughly to ensure every strand is luxuriously coated. Adjust seasoning with salt and pepper to taste.
- Serve instantly, garnished with fresh basil and chopped parsley for a vibrant touch of colour and freshness.
Tips for Success
- Roasting is key: The caramelized edges on the cauliflower add depth and a slightly sweet undertone, elevating the creaminess of the Alfredo.
- Cashew soak time: For an ultra-smooth texture, soak cashews for up to 4 hours or overnight if possible; 20 minutes works for a quicker version but be sure to blend thoroughly.
- Customize your thickness: Adjust the almond milk to get the sauce as thick or thin as you prefer-the sauce will thicken more as it cools.
- Make-ahead: Prepare the sauce in advance and store it separately. Reheat gently and combine with freshly roasted cauliflower and pasta for a speedy meal.
- allergic to nuts? substitute cashews with 1 cup silken tofu plus ¼ cup nutritional yeast for a different creamy base.
