Step‑by‑Step Instructions for Roasted Garlic Cheddar Cauliflower Soup
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking and make cleanup easier. This temperature is perfect for roasting, as it caramelizes the cauliflower and brings out its natural sweetness, creating the flavorful base for your Roasted Garlic Cheddar Cauliflower Soup.
Step 2: Prepare the Cauliflower
In a mixing bowl, toss the cauliflower florets with 1-2 tablespoons of olive oil, and season generously with salt and pepper. Ensure each piece is well-coated, as this will enhance the flavor and texture as they roast. Spread the cauliflower evenly on the prepared baking sheet, making sure there is enough space between each floret for proper roasting.
Step 3: Prepare the Garlic
Next, take a whole head of garlic and slice off the top to expose the cloves. Drizzle a little olive oil over the exposed cloves, and wrap the garlic in foil. Place this foil-wrapped head on the baking sheet alongside the cauliflower. Roasting the garlic will infuse it with a sweet, mellow flavor that will complement the soup beautifully.
Step 4: Roast the Vegetables
Roast the cauliflower and garlic in the preheated oven for 30-35 minutes. Halfway through roasting, give the cauliflower a gentle flip using a spatula to ensure even cooking. You’ll know they’re ready when the cauliflower is tender and golden brown, and the garlic is soft and aromatic—this is the perfect base for your creamy soup.
Step 5: Sauté the Onions
While the vegetables are roasting, heat the remaining olive oil in a large pot over medium heat. Add the chopped onion, and sauté for 5-8 minutes until it’s translucent and fragrant. This step is crucial as it builds the foundational flavor profile for your Roasted Garlic Cheddar Cauliflower Soup.
Step 6: Blend the Ingredients
Once your roasted cauliflower and garlic are ready, carefully squeeze the garlic cloves out of their skins into the pot with the sautéed onions. Add the roasted cauliflower and pour in the vegetable broth. Using an immersion blender or a regular blender, blend the mixture until it’s completely smooth and creamy, creating a delightful consistency for your soup.
Step 7: Simmer with Cheese
Return the blended mixture to the pot, and bring it to a gentle simmer over low heat. Stir in the sharp cheddar cheese, mixing until it’s fully melted and incorporated into the soup. Allow the soup to simmer for another 10-15 minutes, stirring occasionally to ensure all flavors meld beautifully and the texture becomes luxuriously creamy.
Step 8: Serve and Garnish
Finally, ladle the warm Roasted Garlic Cheddar Cauliflower Soup into bowls. Garnish each serving with sliced green onions and a sprinkle of additional cheese for a delightful finish. Pair with crusty sourdough bread for a comforting meal that you and your loved ones will truly enjoy.

Make Ahead Options
These Roasted Garlic Cheddar Cauliflower Soup preparations are perfect for busy home cooks! You can roast the cauliflower and garlic up to 24 hours in advance; simply allow them to cool, then store in an airtight container in the refrigerator. The sautéed onions can also be prepped ahead and kept for up to 3 days. When you’re ready to serve, just blend in the stored cauliflower and garlic with the sautéed onions and vegetable broth, then heat on the stove. Stir in the cheddar cheese until melted, and enjoy a creamy bowl of comfort that tastes just as delicious as if it was freshly made! This way, you can have a warm, hearty meal ready with minimal effort on busy weeknights.

Tips for the Best Roasted Garlic Cheddar Cauliflower Soup
-
Quality Ingredients: Use fresh cauliflower and sharp cheddar for the best flavor. Avoid pre-shredded cheese, as it may contain anti-caking agents that affect melting.
-
Roasting Magic: Make sure to roast until golden. Overcooking can dull the flavors; keep an eye on the garlic to prevent bitterness.

Blend Smoothly: For an ultra-creamy texture, blend the soup until completely smooth. Chunky bits can disrupt the comforting vibe of this Roasted Garlic Cheddar Cauliflower Soup.
