How to Make Roasted Garlic Cheddar Cauliflower Soup
-
Preheat: Start by setting your oven to 400°F (200°C). Line a baking sheet with parchment paper to make cleanup a breeze later!
-
Prepare Cauliflower: Spread your cauliflower florets onto the prepared baking sheet. Drizzle with 1-2 tablespoons of olive oil and sprinkle generously with salt and pepper. Toss to coat.
-
Wrap Garlic: Take the whole head of garlic and peel away the outer layers, leaving the cloves intact. Cut the top off ¼ inch to expose them, then drizzle with olive oil. Wrap in foil and place alongside the cauliflower on the baking sheet.
-
Roast Together: Roast the cauliflower and garlic for 30-35 minutes, turning the florets halfway through. Keep an eye out for a lovely golden color and caramelization!

Sauté Onions: In a pot over medium heat, warm 1 tablespoon of olive oil. Add your diced onion and sauté for about 5-8 minutes, cooking until the onions are translucent and fragrant.
-
Blend Ingredients: Once the cauliflower and garlic are ready, combine them in a blender with the sautéed onions, vegetable broth, salt, and pepper. Blend until you achieve a silky smooth texture, about 1 minute.
-
Simmer Soup: Return the blended mixture to the pot. Squeeze the roasted garlic from its skin into the pot and place it over medium heat. Bring the soup to a light simmer, stirring occasionally.
-
Add Cheese: After 10-15 minutes of simmering, stir in the shredded cheddar cheese until melted and creamy. Taste the soup and adjust seasonings as necessary.

Expert Tips for Roasted Garlic Cheddar Cauliflower Soup
-
Choose Fresh Cauliflower: Look for firm, white heads without any browning. Fresh cauliflower ensures a tastier and creamier Roasted Garlic Cheddar Cauliflower Soup.
-
Proper Roasting: Don’t overcrowd the baking sheet; this helps the cauliflower achieve optimal caramelization. If crowded, it may steam rather than roast.
-
Sauté Onions Thoroughly: Make sure the onions are translucent before blending, as this adds depth of flavor. Undercooked onions can taste harsh in the soup.
-
Blend in Batches: If using a smaller blender, blend the ingredients in batches. Overfilling can lead to messy spills and uneven texture.
-
Adjust Cheese to Taste: Start with less cheddar if you prefer a lighter soup. You can always add more for that rich, cheesy flavor at the end!
-
Taste and Season: Always taste the soup before serving; a pinch of salt or a dash of pepper can elevate the flavor significantly in your Roasted Garlic Cheddar Cauliflower Soup.

-
Fridge: Store any leftovers in an airtight container in the fridge for up to 3 days. Be sure to let the soup cool completely before sealing it to preserve freshness.
