The Magic in This Recipe
Roasting transforms humble cauliflower into something nutty and aromatic—like turning a backup singer into the headliner. A touch of onion and garlic builds savory depth, while a squeeze of lemon brightens the finish.
A small spoon of Greek yogurt delivers creaminess without heavy dairy. The result? Velvety, low-cal, and shockingly satisfying.

kcalGather Your Ingredients
1 large head cauliflower (about 2 to 2.5 lbs), cut into florets
1 medium yellow onion, roughly chopped
4 cloves garlic, peeled
2 tablespoons olive oil
4 cups low-sodium vegetable or chicken broth
1/2 teaspoon smoked paprika (optional, but awesome)
1/4 teaspoon ground cumin
1 bay leaf
1/4 cup plain nonfat Greek yogurt (or light coconut milk for dairy-free)
1–2 tablespoons lemon juice, to taste
Salt and black pepper, to taste
Optional garnishes: chopped chives or parsley, red pepper flakes, toasted almonds or pumpkin seeds, drizzle of olive oil
Step-by-Step Guide
- Preheat the oven: Set to 425ºF (220ºC). High heat equals maximum caramelization—your flavor booster.
- Prep the veg: Toss cauliflower florets, onion, and garlic with olive oil, smoked paprika, cumin, salt, and pepper on a large sheet pan. Spread in a single layer for even browning.
- Roast to golden: Bake 25–30 minutes, flipping once. You want edges browned and centers tender. If the garlic looks done early, pull it off the tray and save it.
- Simmer the base: In a pot, combine roasted veg, broth, and bay leaf. Bring to a simmer for 5–8 minutes to meld flavors. Remove the bay leaf.
- Blend it smooth: Use an immersion blender in the pot, or transfer carefully to a standing blender. Blend until silky. Add more broth if you want it thinner.
- Creamy finish: Stir in Greek yogurt and lemon juice. Taste, then adjust salt, pepper, and acidity. A pinch more smoked paprika? Go for it.
- Serve like a pro: Ladle into bowls and top with herbs, a few crunchy seeds, red pepper flakes, and a tiny drizzle of olive oil for shine. Boom—restaurant vibes.
Storage Instructions
- Fridge: Store in an airtight container for up to 4 days.
The flavors deepen by day two—chef’s secret.
- Freezer: Freeze up to 3 months. Thaw overnight in the fridge, then reheat gently and whisk to restore creaminess.
- Reheat: Warm on low, stirring often. If it thickens, add a splash of broth or water.
Wholesome Benefits
- Low calorie, high satiety: Roasted cauliflower delivers bulk and fiber, keeping hunger in check without caloric overload.
- Micronutrient dense:</-strong> Cauliflower brings vitamin C, K, folate, and antioxidants.
Onion and garlic add allicin and quercetin—small names, big impact.
- Better-for-you fats: A modest hit of olive oil supports absorption of fat-soluble nutrients and improves mouthfeel.
- Protein assist: Greek yogurt adds a touch of protein and creaminess without the heavy cream tax.

Tips to Prevent Errors
- Don’t crowd the pan: Overlapping florets steam instead of brown. Use two pans if needed.
- Watch the garlic: Whole cloves can brown fast.
If they’re golden early, pull them off and finish roasting the rest.
- Season in layers: Salt on the sheet pan, then adjust after blending. It’s soup, not a salt lick.
- Blend safely: Vent the blender lid and cover with a towel. Hot soup + sealed blender = kitchen geyser.
- Balance the finish: If it tastes flat, add lemon or a pinch of salt.
If it’s too sharp, stir in a touch more yogurt.
- Texture control: For extra-smooth soup, blend longer and strain. For rustic, pulse briefly and leave tiny bits.

Other Versions to Try
- Curried Cauliflower: Add 1–2 teaspoons curry powder and 1/2 teaspoon turmeric before roasting; garnish with cilantro and a dollop of yogurt.
- Garlic-Parmesan (not dairy-free): Stir in 1/4 cup grated Parmesan at the end for umami depth.
- Spicy Harissa: Blend in 1–2 teaspoons harissa paste; top with toasted almonds and parsley.
- Coconut-Lime (dairy-free): Swap yogurt for 1/3 cup light coconut milk; finish with lime juice and toasted coconut flakes.
- Protein Boost: Add a can of white beans during the simmer for extra creaminess and protein, IMO a power move.
FAQ
Can I make this vegan?
Yes. Use vegetable broth and replace Greek yogurt with light coconut milk or unsweetened plant yogurt.
Adjust lemon to taste so the flavors stay bright.
What if I don’t have an immersion blender?
Use a countertop blender in batches. Fill halfway, vent the lid, cover with a towel, and blend until smooth. Return to the pot and adjust thickness with broth.
How do I make it thicker or thinner?
For thicker soup, reduce the broth by 1/2 to 1 cup or simmer longer after blending.
For thinner, add warm broth or water gradually until it hits your preferred consistency.
Can I roast the cauliflower ahead?
Totally. Roast up to 48 hours in advance, refrigerate, then simmer with broth when ready. The roasted flavor actually intensifies a bit—nice little cheat code.
Is this meal prep friendly?
Absolutely.
Portion into containers, add garnishes right before eating, and store in the fridge up to 4 days or freeze for a rainy day.
What can I serve with it?
Pair with a crusty slice of whole-grain bread, a simple arugula salad, or a protein side like grilled chicken or crispy chickpeas. It plays well with others.
