How to Make Roasted Garlic Cauliflower Soup Recipe
-
Preheat: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. This high heat helps caramelize the garlic and cauliflower for deep, nutty sweetness.
-
Prepare Veggies: Wash and cut cauliflower into bite-size florets, slice garlic bulbs in half horizontally, then toss everything in olive oil, a pinch of salt, and cracked black pepper for balanced flavor.
-
Roast Vegetables: Arrange florets and garlic cut-side up on the sheet, then roast until cauliflower is tender and golden brown, about 25–30 minutes.
-
Sauté Onion: In a soup pot over medium heat, warm a splash of olive oil, add diced onion, and cook until soft and translucent, about 5–7 minutes, stirring occasionally.
-
Combine Ingredients: Add roasted cauliflower and squeeze roasted garlic cloves out of skins into the pot, pour in vegetable broth, and add a few thyme sprigs for aromatic depth.
-
Simmer Soup: Bring to a gentle boil, then reduce heat and let the soup simmer uncovered for 10–15 minutes, allowing the flavors to marry and the cauliflower to soften completely.
-
Blend: Remove thyme sprigs, then use an immersion blender to puree the soup directly in the pot until silky smooth and creamy, stopping to adjust texture as needed.
-
Finish and Serve: Stir in freshly squeezed lemon juice, taste and adjust seasoning with salt and pepper, and swirl in coconut milk if you’d like extra creamy richness.
Optional: Top with chopped parsley or a drizzle of chili oil for a flavor kick.

Roasted Garlic Cauliflower Soup Recipe FAQs
How do I select the best cauliflower and garlic for this soup?
Choose a fresh cauliflower head that is firm, with tight, white florets and no dark spots. For garlic, pick bulbs that are plump and feel heavy for their size—avoid any with soft spots or sprouting green shoots, as those can taste bitter.
Can I store leftover Roasted Garlic Cauliflower Soup, and for how long?
Absolutely! Store your soup in an airtight container in the refrigerator for up to 3 days. Make sure the soup cools completely before sealing to keep the flavors fresh and prevent moisture buildup.
What’s the best way to freeze this soup for later?
Freezing is a great option! Let the soup cool completely, then transfer it to freezer-safe containers or heavy-duty freezer bags. Leave about an inch of headspace for expansion. Label with the date and freeze for up to 3 months. When ready to enjoy, thaw in the fridge overnight and reheat gently on the stove.
What should I do if my soup tastes too bland or lacks depth?
No worries! Sometimes roasting time might need a tweak—make sure your garlic and cauliflower are deeply golden to bring out that natural sweetness. After blending, taste and adjust seasoning with salt, pepper, and a fresh splash of lemon juice to brighten flavors. Adding a bit of coconut milk can also enrich and balance the taste.
Is this soup safe for pets or people with garlic allergies?
This soup contains roasted garlic, which is delicious but can be harmful to pets like dogs and cats. If you have any food allergies or are cooking for sensitive eaters, consider omitting the garlic or substituting with roasted shallots or leeks.
