How to Make Roasted Garlic Cheddar Cauliflower Soup
Step 1: Preheat the Oven
Preheat your oven to 400 degrees F. Line a baking sheet with parchment paper to prevent sticking.
Step 2: Cook the Veggies
Add cauliflower florets to the pan. Drizzle with 1-2 tablespoons of olive oil and season generously with salt and pepper; toss to combine. For the garlic:
Peel away the outer papery layers of the whole garlic head while leaving individual clove skins intact.
Cut about ¼ inch off from the top of each clove so they are exposed.
Drizzle olive oil over the top of the garlic, wrap it in foil loosely, and place it on the baking sheet with cauliflower.
Roast both for 30-35 minutes, flipping halfway through until golden brown.
Step 3: Cook the Onion
In a pot over medium heat, add 1 tablespoon of olive oil. Once hot, add diced onion and sauté for 5–8 minutes until translucent.
Step 4: Blend the Soup
In a large blender, combine sautéed onion, roasted cauliflower, roasted garlic (squeezed out from its skin), broth, salt, and pepper. Blend until smooth—about one minute. Return it to the pot over medium heat.
Step 5: Finish It Off
Bring your soup to a light simmer. Stir in shredded cheddar cheese, letting it melt into the mixture. Simmer for another 10–15 minutes. Taste and adjust seasoning if needed. Garnish with green onions and extra grated cheese before serving with crusty bread or croutons. Enjoy!

How to Perfect Roasted Garlic Cheddar Cauliflower Soup
To ensure your Roasted Garlic Cheddar Cauliflower Soup turns out perfectly every time, consider these helpful tips.

-
Blend thoroughly: For a silky smooth consistency, blend your soup until completely smooth, ensuring no chunks remain.
-
Adjust seasoning: Taste your soup before serving; adding salt or pepper can make a significant difference in flavor.
-

Common Mistakes to Avoid
Making Roasted Garlic Cheddar Cauliflower Soup can be easy, but there are common pitfalls to watch out for.
- Overcooking the cauliflower: This can lead to a mushy texture. Roast just until the florets are golden and tender.
- Not seasoning properly: Under-seasoning can make the soup bland. Always taste and adjust salt and pepper before serving.
- Skipping the blending step: Failing to blend thoroughly results in a chunky soup. Aim for a smooth, creamy consistency by blending for at least one minute.
- Using low-quality cheese: Cheap cheddar can affect flavor. Choose a sharp, high-quality cheddar for the best taste.
- Omitting garnishes: Skipping toppings like green onions or croutons makes the dish less appealing. Add these for extra flavor and texture.
