Roasted Garlic Cheddar Cauliflower Soup Ingredients

For the Soup

  • Cauliflower – 1 large head, cut into florets; this is the star of our Roasted Garlic Cheddar Cauliflower Soup, lending a creamy texture.
  • Olive Oil – 3 tablespoons, divided; use this for roasting the veggies and sautéing the onion for flavor enhancement.
  • Salt and Pepper – Freshly ground; always season to taste for that perfect flavor balance.
  • Garlic – 1 head; whole roasted garlic gives a sweet, mellow richness that pairs beautifully with cheddar.
  • Onion – 1 medium yellow, diced; sautéing the onion adds depth and sweetness to the soup.
  • Vegetable Broth – 4 cups (or chicken broth for non-vegetarians); this forms the soup's base and adds layers of flavor.
  • Sharp Cheddar Cheese – 1 heaping cup, shredded; it melts beautifully, enriching the soup's creaminess.

For Garnishing

  • Green Onion – Sliced; adds a fresh, vibrant crunch on top.
  • Extra Cheddar – For topping; because who can resist more cheese?
  • Croutons or Toasted Sourdough Bread – Perfect for serving; provides a delightful crunch that contrasts the creamy soup.

Step‑by‑Step Instructions for Roasted Garlic Cheddar Cauliflower Soup

Step 1: Preheat the Oven
Begin by preheating your oven to 400 degrees F. Line a baking sheet with parchment paper to prevent sticking. This step sets the stage for roasting the cauliflower and garlic, which will bring out their natural sweetness and flavor in the Roasted Garlic Cheddar Cauliflower Soup.

Step 2: Prepare the Cauliflower
Spread the cauliflower florets evenly on the prepared baking sheet. Drizzle 1–2 tablespoons of olive oil over the florets, ensuring each piece is coated, then season generously with freshly ground salt and pepper. Give them a good toss, so each floret is well-seasoned, ready for roasting.

Step 3: Wrap the Garlic
Take the whole head of garlic and peel off the outer papery layers. Slice off about ¼ inch from the top of the cloves, drizzle with olive oil, and wrap it snugly in foil. Place the garlic on the baking sheet alongside the cauliflower. This will roast and caramelize beautifully, enhancing the flavor of your soup.

Step 4: Roast the Vegetables
Roast the cauliflower and garlic in the preheated oven for 30–35 minutes, flipping the cauliflower halfway through. Look for a golden, caramelized hue on the florets—the bright color indicates they’re developing rich, sweet flavors for your Roasted Garlic Cheddar Cauliflower Soup.

Step 5: Sauté the Onion
While the veggies roast, heat 1 tablespoon of olive oil in a large pot over medium heat. Add the diced onion and sauté for 5–8 minutes until it becomes translucent and fragrant. This toasting process builds depth in flavor for the base of your soup.

Step 6: Blend the Ingredients
Once the cauliflower and garlic are roasted, carefully squeeze the soft garlic cloves out of their skins. In a large blender, combine the roasted cauliflower, roasted garlic, sautéed onion, vegetable broth, salt, and pepper. Blend on high for about 1 minute until the mixture is silky smooth and luscious.

Step 7: Heat the Soup
Pour the smooth mixture back into the pot and heat over medium heat. Bring it to a light simmer, stirring occasionally. Once simmering, gently fold in the heaping cup of shredded sharp cheddar cheese. Let it simmer for 10–15 minutes, adjusting the seasonings as necessary for that perfect balance.

Step 8: Garnish and Serve
To finish your Roasted Garlic Cheddar Cauliflower Soup, ladle the velvety goodness into bowls. Garnish with sliced green onion and additional cheddar on top for a pop of color and flavor. Serve with crusty toasted sourdough or your bread of choice for the perfect comforting meal.

Roasted Garlic Cheddar Cauliflower Soup Recipe FAQs

What is the best way to choose ripe cauliflower?
Absolutely! Look for cauliflower heads that are compact, firm, and free from dark spots or brown discoloration. The leaves should be fresh and green, indicating that the cauliflower is fresh and at its peak. If you notice any soft or yellow areas, it's best to select another head.

How do I store leftover Roasted Garlic Cheddar Cauliflower Soup?
You can store your soup in an airtight container in the fridge for up to 3 days. To maintain its creamy texture, simply reheat it gently on the stovetop. If it seems too thick upon reheating, add a splash of broth or water to restore its lusciousness.

Can I freeze Roasted Garlic Cheddar Cauliflower Soup?
Very! To freeze the soup, allow it to cool completely before transferring it to freezer-safe containers. Leave some room at the top, as the soup will expand while freezing. It’s best enjoyed within 3 months. When you’re ready to eat, thaw it in the fridge overnight and reheat on low heat, stirring occasionally for an even consistency.

What if my soup turns out too thick or chunky?
Don’t worry, this happens! If your soup is thicker than you'd like after blending, add vegetable or chicken broth a little at a time while stirring until you reach your desired consistency. If it’s chunky, blend it longer until the texture smooths out. Remember, it’s all about, tasting, adjusting, and making it your own!

Are there any dietary considerations for this soup?
Absolutely, it’s important to note that this recipe is vegetarian-friendly when using vegetable broth. If you need it to be dairy-free, try substituting the cheese with a non-dairy alternative that melts well, and use a plant-based cream to add creaminess. Always double-check for individual allergies, especially with cheese or broth ingredients.

How long can I keep this soup in the fridge after making it?
You can safely store your Roasted Garlic Cheddar Cauliflower Soup in the refrigerator for about 3 days. Be sure to keep it in a sealed container to lock in freshness. When reheating, just add a little broth if it has thickened too much—that’s usually the case with soups!
