1 large head of cauliflower, cut into florets – about 2 lbs, this is our star!

2 tablespoons olive oil – for coating and roasting the veggies
1 teaspoon salt – enhances all the flavors
1/2 teaspoon black pepper – a little spice to balance the sweetness
1 large onion, chopped – about 1.5 cups, adds aromatic depth

3 cloves garlic, minced – essential for that savory kick
4 cups vegetable broth – the liquid base for our soup
1 cup milk (or dairy-free alternative) – for that luxurious creamy texture; use whole milk for richness or almond/oat milk for vegan options

How to Make Easy Roasted Cauliflower Soup

This recipe makes whipping up a delicious batch of soup surprisingly simple. Get ready for a rich, creamy bowl that’s bursting with flavor!

Step 1: First things first, let’s preheat your oven to 400°F (200°C). This high heat is crucial for getting those lovely caramelized bits on the cauliflower.

Step 2: Grab your cauliflower florets and toss them with the 2 tablespoons of olive oil, 1 teaspoon of salt, and 1/2 teaspoon of black pepper right on a baking sheet. Make sure each floret is lightly coated.
Step 3: Spread the cauliflower in a single layer on the baking sheet. Roast for 20-25 minutes, or until the edges are tender and have those beautiful golden-brown spots. The kitchen will start smelling amazing!

Step 4: While your cauliflower is doing its magic in the oven, chop up your 1 large onion. Heat a large pot or Dutch oven over medium heat and sauté the onion until it’s nice and softened, about 5-7 minutes.

Step 5: Add the 3 cloves of minced garlic to the pot with the onions. Cook for just 1 minute more, stirring constantly, until it’s wonderfully fragrant. Be careful not to burn the garlic!
Step 6: Once the cauliflower is perfectly roasted, carefully add it to the pot with the onions and garlic. Pour in the 4 cups of vegetable broth.
Step 7: Bring the mixture to a boil, then reduce the heat to low, cover, and let it simmer gently for about 10 minutes. This lets all those delicious roasted flavors meld together.

Step 8: Now it’s time to get it smooth! Carefully transfer the hot soup to a blender. Alternatively, you can use an immersion blender directly in the pot. Blend until the soup is completely smooth and has that luxurious, creamy texture. This is where the magic happens for your creamy roasted cauliflower soup!
Step 9: Stir in the 1 cup of milk (or your chosen dairy-free alternative) until well combined. Gently heat the soup through over low heat, but be sure not to let it boil, as this can cause the milk to separate.
Step 10: Ladle your beautiful, easy roasted cauliflower soup into bowls. Garnish with the 1/4 cup of chopped fresh parsley for a burst of color and freshness. Enjoy this delightful roasted cauliflower bisque right away!
