This simple step transforms the cauliflower, caramelizing it to perfection and banishing watery mush forever. Get ready to fall in love with this game-changing side dish!

Ingredients

• 1 large head cauliflower, about 2 lbs or 900g
• 6 cloves garlic, peeled
• 2 tablespoons / 30 ml avocado oil or olive oil
• Sea salt and ground black pepper, to taste
• ½ cup / 115 g mayonnaise, store-bought or homemade
• ½ cup / 120 ml unsweetened almond or coconut milk
• 2 tablespoons / 8 g chopped fresh chives, plus more for garnish
• Garlic and Herb–Infused Olive Oil, for garnish (optional)
• Special Equipment
• Food processor

Instructions

1. Directions
2. Preheat the oven to 425°F / 220°C.
3. Core the head of cauliflower and cut it into florets. Spread the florets and the garlic cloves in a single layer across a rimmed baking sheet. Drizzle the oil over the top, toss to coat, and sprinkle generously with salt and pepper.
4. Roast for 25 to 30 minutes, until the cauliflower and garlic are tender and golden brown.
5. Put the roasted cauliflower and garlic, mayonnaise, almond milk, and chives in a food processor. Pulse until smooth and fluffy. Taste and add more salt and pepper, if desired.
6. Drizzle the puree with the infused olive oil before serving, if desired.

Pro Tips

• For the best flavor and texture, spread the cauliflower in a single layer on the baking sheet. Overcrowding the pan will cause it to steam instead of roast.
• Let the roasted cauliflower cool for 5-10 minutes before adding it to the food processor. This allows excess steam to escape, preventing a watery final product.
• For an extra creamy and rich mash, substitute half of the mayonnaise with full-fat cream cheese or add 2 tablespoons of softened butter.

FAQ

Q: Why roast the cauliflower instead of boiling it
A: Roasting the cauliflower caramelizes it, creating a deep, rich flavor and preventing the watery, bland texture often found in boiled cauliflower mash. This step is the secret to a fluffy, potato-like consistency.

Q: How do I prevent my cauliflower mash from being watery
A: The key is to roast the cauliflower, which removes excess moisture. Also, letting the roasted cauliflower cool for 5-10 minutes before processing allows steam to escape, further ensuring a thick, non-watery mash. Avoid overcrowding the baking sheet to promote roasting over steaming.

Q: Can I make this cauliflower mash dairy-free
A: Yes, this recipe is easily made dairy-free. It uses mayonnaise and unsweetened almond or coconut milk instead of traditional dairy products. Just ensure your chosen mayonnaise is also dairy-free.

Q: How can I make this mash even richer
A: For an extra creamy and rich mash, you can substitute half of the mayonnaise with full-fat cream cheese or add 2 tablespoons of softened butter to the food processor along with the other ingredients.
