How to Make Roasted Cauliflower Soup with Za’atar and Crispy Croutons Recipe
Step 1: Roast the Vegetables
Start by preheating your oven to 400°F (200°C)—this high heat caramelizes the cauliflower and brings out their natural sweetness. Toss the cauliflower florets, quartered shallots, and garlic cloves in olive oil and sprinkle with salt, pepper, oregano, smoked paprika, and cumin. Make sure everything is evenly coated with those beautiful spices. Spread the veggies in a single layer on a baking dish and roast for about 20-25 minutes until they’re tender and turning golden at the edges—this step builds the flavor foundation of the soup.
Step 2: Simmer with Bone Broth
Once perfectly roasted, transfer the cauliflower, garlic, and shallots to a medium saucepan and pour in the bone broth. Bring the mixture to a gentle simmer over medium heat to marry the flavors. This simmering infuses the broth with the richness and smokiness of the roasted veggies, grounding the soup’s taste with comforting umami.
Step 3: Puree Until Silky Smooth
Using an immersion blender right in the pot, blend the soup until it’s completely smooth and velvety. If you don’t have an immersion blender, carefully transfer batches to a regular blender—just be sure to let it cool a bit first! This silky texture is what makes the soup so soothing and luxurious, turning humble cauliflower into something truly special.
Step 4: Enrich and Adjust Seasonings
Return the blended soup to low heat and stir in the heavy cream to add that gorgeous richness. Let it warm through for a few minutes, then taste and tweak your seasonings with a little extra salt or pepper if needed. This final step ensures your soup is perfectly balanced—rich, warm, and ready to serve.
How to Serve Roasted Cauliflower Soup with Za’atar and Crispy Croutons Recipe
Garnishes
I love finishing this soup with a drizzle of extra heavy cream for that elegant swirl, a generous handful of crunchy, golden croutons for texture contrast, and a sprinkle of za’atar seasoning to add a bright, herby zing. These garnishes elevate each spoonful and make your soup look as fantastic as it tastes.
Side Dishes
This soup pairs beautifully with crusty bread for dipping or a crisp green salad dressed lightly with lemon vinaigrette to balance the creamy richness. For a heartier meal, serve alongside roasted chicken or a warm grain bowl to round out the experience.
Creative Ways to Present
Try serving the soup in rustic bread bowls for a cozy, dramatic touch, or layer the croutons and za’atar on top just before serving to keep their crunch. You can also add a sprinkle of toasted pine nuts or a drizzle of chili oil for an unexpected twist that will wow your guests.
Make Ahead and Storage
Storing Leftovers
Store any leftover roasted cauliflower soup in an airtight container in the refrigerator for up to 4 days. To keep the texture fresh, add your croutons just before serving rather than storing them in the soup.
Freezing
This soup freezes wonderfully! Pour cooled soup into freezer-safe containers, leaving some room for expansion, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating
Rewarm the soup gently on the stove over low-medium heat, stirring occasionally until heated through. Add a splash of cream or broth if it’s too thick after refrigeration or thawing, and adjust seasoning to refresh those vibrant flavors.
FAQs
-
Can I make this soup vegan?
Absolutely! Swap the bone broth for a rich vegetable broth and replace heavy cream with coconut cream or cashew cream to keep that silky texture while making it fully plant-based.
-
What is za’atar and can I substitute it?
Za’atar is a Middle Eastern herb blend combining thyme, sumac, sesame seeds, and other spices, offering a tangy, herby punch. If you don’t have it, try mixing thyme, oregano, sesame seeds, and a bit of lemon zest for a similar effect.
-
Can I use fresh herbs instead of dried spices?
Fresh herbs can be lovely but may alter the roasting flavor profile. If you substitute, add fresh herbs after blending the soup to preserve their brightness and avoid burning during roasting.
-
What type of croutons work best?
Homemade croutons tossed in olive oil, garlic, and a sprinkle of za’atar or smoked paprika work perfectly to echo the soup’s flavors and give you that delightful crunch.
