Shopping List
- 1 large head cauliflower (about 2 to 2.5 pounds), cut into florets
- 1 medium yellow onion, chopped
- 3–4 cloves garlic, minced
- 3 tablespoons olive oil, divided
- 4 cups low-sodium vegetable or chicken broth
- 1 cup unsweetened milk of choice (oat, almond, or dairy milk) or 1/2 cup coconut milk for extra creaminess
- 1–2 tablespoons fresh lemon juice (plus zest, optional)
- 1/4 teaspoon ground nutmeg (optional but great)
- Salt and freshly ground black pepper
- Optional garnishes: chopped chives or parsley, a drizzle of olive oil, red pepper flakes, toasted almonds, pumpkin seeds, or a spoon of Greek yogurt
How to Make It

- Prep and roast the cauliflower: Heat the oven to 425°F (220°C). Toss cauliflower florets with 2 tablespoons olive oil, salt, and pepper.
Spread on a sheet pan and roast for 25–30 minutes, until tender with caramelized edges.
- Sauté aromatics: In a large pot, warm the remaining 1 tablespoon olive oil over medium heat. Add onion with a pinch of salt and cook 5–7 minutes until soft and lightly golden. Stir in garlic and cook 30 seconds, just until fragrant.
- Simmer with broth: Add roasted cauliflower to the pot.
Pour in broth and bring to a gentle simmer. Cook 10 minutes to let flavors come together.
- Add milk and season: Stir in your milk of choice. Add nutmeg, more salt, and pepper to taste.
Keep heat low so milk doesn’t boil.
- Blend until silky: Use an immersion blender to puree until smooth. For extra-smooth texture, transfer to a countertop blender in batches, venting the lid. Blend until creamy.
- Brighten: Stir in lemon juice (and a little zest if using).
Taste and adjust seasoning—add salt for depth, pepper for bite, or more lemon for lift.
- Serve and garnish: Ladle into bowls. Finish with a drizzle of olive oil, chopped herbs, and any crunchy topping you like.
Keeping It Fresh
- Fridge: Store in an airtight container for up to 4 days. The flavor gets even better by day two.
- Reheat: Warm on the stove over low heat, stirring often.
If it thickens, loosen with a splash of broth or water.
- Freezer: Freeze for up to 3 months. Cool completely before freezing. Thaw overnight in the fridge, then reheat gently.
Blend again briefly if separation occurs.
Benefits of This Recipe
- Nutrient-dense: Cauliflower brings fiber, vitamin C, vitamin K, and antioxidants with minimal calories.
- Light yet satisfying: The creamy texture keeps it comforting without feeling heavy.
- Budget-friendly: Uses inexpensive, accessible ingredients you can find year-round.
- Meal-prep ready: Easy to batch cook and pack for lunches.

Pitfalls to Watch Out For
- Skipping the roast: Roasting deepens flavor and adds natural sweetness. Don’t skip it unless you’re in a real rush.
- Boiling the milk: High heat can cause curdling or a grainy texture. Keep it to a gentle simmer.
- Under-seasoning: Cauliflower is mild.
Taste often and add enough salt, pepper, and lemon to wake it up.
- Overfilling the blender: Hot soup expands. Blend in batches and vent the lid to avoid splatters.
- Too thick or too thin: Adjust with broth to thin or simmer longer to reduce. Aim for a spoon-coating consistency.
Alternatives
- Vegan/dairy-free: Use vegetable broth and plant-based milk.
Coconut milk adds extra creaminess; oat milk keeps it neutral.
- Protein boost: Stir in white beans before blending, or top with shredded chicken or crispy chickpeas.
- Extra veg: Add a parsnip or a small potato for body, or a handful of spinach at the end for color.
- Cheesy touch: Blend in a small handful of grated Parmesan for savory depth (skip for dairy-free).
- Spice it up: Add a pinch of curry powder, smoked paprika, or cumin while sautéing the onion.
- Lower sodium: Use low-sodium broth and season with lemon and herbs to boost flavor.
FAQ
Can I make this without roasting the cauliflower?
Yes, you can simmer the cauliflower directly in the broth until tender. The soup will still be good, but it won’t have the same sweetness and depth you get from roasting.
What’s the best milk for creaminess?
For the richest texture without heavy cream, use canned light coconut milk or a creamy oat milk. Dairy milk works well too.
Avoid sweetened plant milks.
How can I thicken the soup naturally?
Let it simmer uncovered to reduce slightly, or blend in a small cooked potato or some white beans. Both add body without changing the flavor much.
Can I use frozen cauliflower?
Absolutely. Roast it straight from frozen until browned, or simmer it in the broth.
Roasting from frozen may take a few extra minutes.
What should I serve with it?
Crusty whole-grain bread, a simple green salad, or a side of roasted chickpeas makes it a complete, satisfying meal.
How do I make it kid-friendly?
Keep spices mild, blend very smooth, and finish with a little grated cheese on top. A drizzle of olive oil also adds a buttery feel kids tend to like.
Why add lemon juice?
A splash of acid brightens the flavors and balances the natural sweetness of cauliflower. It’s the small step that makes the soup taste lively.
