Step‑by‑Step Instructions for Roasted Garlic Cheddar Cauliflower Soup
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup. While the oven heats, chop cauliflower into florets, then toss them in 1-2 tablespoons of olive oil, salt, and pepper. Place the cauliflower on the baking sheet alongside a whole head of garlic, top cut off and drizzled with a bit of oil, wrapped in foil for roasting.
Step 2: Roast the Vegetables
Roast the cauliflower and garlic in the preheated oven for 30-35 minutes, flipping the cauliflower halfway through to ensure even browning. The cauliflower should be tender and golden while the garlic becomes sweet and caramelized. Once done, remove them from the oven and let them cool slightly before handling, as the garlic will be extremely hot.
Step 3: Sauté the Onion
In a large pot over medium heat, warm the remaining olive oil. Dice one onion and add it to the pot, sautéing for 5-8 minutes until the onion is translucent and aromatic. Stir occasionally to prevent sticking and ensure an even cooking, as the onion begins to soften and develop a gentle sweetness, creating a flavorful base for your Roasted Garlic Cheddar Cauliflower Soup.
Step 4: Blend the Soup Base
Once the vegetables are roasted and your onion is cooked, squeeze the roasted garlic from its skins directly into the pot. Add the roasted cauliflower and pour in your vegetable broth. With an immersion blender, puree the mixture until it’s completely smooth and creamy, or transfer it to a countertop blender in batches if needed. This step creates the luscious texture that defines the creamy nature of the soup.
Step 5: Incorporate the Cheese
Return the blended mixture to the pot over medium heat and bring it to a gentle simmer. Gradually stir in the shredded sharp cheddar cheese, allowing it to melt into a velvety consistency, which should take about 10-15 minutes. Keep stirring, enjoying the inviting aroma of the melting cheese, ensuring that every bit is incorporated into your Roasted Garlic Cheddar Cauliflower Soup.
Step 6: Final Adjustments and Serve
Taste the soup and adjust the seasoning with additional salt and pepper as needed. Remove from heat and ladle the soup into serving bowls. Garnish with chopped green onions or extra cheddar for that perfect finishing touch. Pair your comforting bowl of Roasted Garlic Cheddar Cauliflower Soup with crusty bread on the side for a hearty and satisfying meal.

How to Store and Freeze Roasted Garlic Cheddar Cauliflower Soup
Fridge: Store your Roasted Garlic Cheddar Cauliflower Soup in an airtight container for up to 3 days. Reheat gently on the stovetop, adding a splash of broth to regain creaminess.
Freezer: For longer storage, freeze the soup in a freezer-safe container for up to 1 month. Label with the date, and thaw in the fridge overnight before reheating.
Reheating: When reheating, do so over low heat, stirring occasionally, and adding a bit of broth or cream as needed to achieve the desired consistency.
Avoid Overheating: Be mindful not to boil the soup when reheating, as this may separate the creamy texture and affect the flavor of your delicious Roasted Garlic Cheddar Cauliflower Soup.

Roasted Garlic Cheddar Cauliflower Soup Recipe FAQs
How do I know if my cauliflower is ripe?
Absolutely! When selecting cauliflower, look for heads that are firm and have tight, compact florets. The color should be bright white with no dark spots or blemishes. If you see any brown patches or it feels soft, it’s best to choose a different one, as it may be past its prime.
What’s the best way to store leftover soup?
Very! To store your Roasted Garlic Cheddar Cauliflower Soup, transfer it to an airtight container and refrigerate for up to 3 days. Be sure to let the soup cool before sealing it tightly. When you’re ready to enjoy it again, simply reheat over low heat on the stovetop, adding a splash of broth if necessary to restore its creamy texture.
Can I freeze this soup for later use?
Absolutely! To freeze your Roasted Garlic Cheddar Cauliflower Soup, let it cool completely, then pour it into a freezer-safe container, leaving some space at the top for expansion. Seal and label with the date; it can be stored for up to 1 month. When you’re ready to enjoy, thaw it overnight in the refrigerator and gently reheat on the stovetop, stirring frequently.
What should I do if my soup is too thick?
If you find that your soup has turned out thicker than desired, fear not! Simply stir in a splash of vegetable broth or water while reheating until you reach your desired consistency. For a richer flavor, you can also add a bit of cream. This will not only help with the texture but enhance the overall taste of your Roasted Garlic Cheddar Cauliflower Soup.
Are there any dietary considerations with this recipe?
Definitely! This soup is vegetarian-friendly, but if you’re serving it to someone with dairy allergies, you can use a non-dairy cheese alternative and coconut milk for creaminess.
