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) and lining a baking sheet with parchment paper. This will prevent sticking and ensure even roasting. While the oven is heating, gather your cauliflower florets and garlic head, preparing for a delightful roasting session that builds the soup’s flavor profile.

Step 2: Prepare the Cauliflower
In a large bowl, toss the cauliflower florets with 1-2 tablespoons of olive oil, salt, and pepper. Make sure each piece is well-coated for optimal roasting. Spread the seasoned florets out in a single layer on the prepared baking sheet, allowing them room to caramelize beautifully during the roasting process.

Step 3: Roast the Garlic
Next, for the garlic, slice off about ¼ inch from the top of the whole head to expose the cloves. Drizzle it with a small amount of olive oil, wrap it in foil to keep it moist, and place it on the same baking sheet as the cauliflower. Roast everything together in the preheated oven for 30-35 minutes, until the cauliflower is golden brown and tender.

Step 4: Sauté the Onion
While your vegetables are roasting, heat 1 tablespoon of olive oil in a large pot over medium heat. Once the oil shimmers, add the diced onion and sauté for 5-8 minutes, stirring frequently until it becomes soft and translucent. This step adds a beautiful base flavor to your Roasted Cauliflower Soup.

Step 5: Blend the Ingredients
After the cauliflower and garlic have roasted, add them to your pot along with the sautéed onion. Pour in 4 cups of vegetable broth, and season with additional salt and pepper if desired. Using an immersion blender or a regular blender, blend the mixture until it reaches a smooth, creamy consistency, ensuring no chunks remain.

Step 6: Simmer and Incorporate Cheese
Return the blended soup to the pot and bring it to a gentle simmer over low heat. Stir in the shredded sharp cheddar cheese gradually, allowing it to melt into the soup. Taste and adjust the seasoning as needed, ensuring the flavors of your Roasted Garlic Cheddar Cauliflower Soup are just right before serving.

Step 7: Serve and Garnish
Ladle the hot soup into bowls, garnishing each with sliced green onions and an extra sprinkle of cheddar for a burst of color and flavor. Serve it alongside croutons or toasted bread to enhance the cozy experience. Enjoy the creamy richness of your homemade Roasted Cauliflower Soup!

Storage Tips for Roasted Cauliflower Soup

Fridge: Allow the soup to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3 days.

Expert Tips for Roasted Cauliflower Soup

Roasting Perfection: Ensure your cauliflower is well-spread on the baking sheet to avoid steaming. This helps achieve that rich, caramelized flavor in your roasted cauliflower soup.
