Recipe Directions
- Start by preheating your oven to 450 degrees F (230 degrees C).
- Place your cauliflower florets into a small roasting pan. Drizzle them with the flavored olive oil.
- Season your cauliflower with nutmeg, garlic powder, salt, and pepper. Toss everything together until the cauliflower is well coated in oil and seasonings.
- Roast the cauliflower in your preheated oven. Make sure to give the cauliflower a good stir every 10 minutes.
- Continue roasting until the cauliflower is golden brown and tender. This should take between 30 to 40 minutes. Once done, remove the pan from the oven and set it aside.
- While the cauliflower is roasting, you can prepare your soup base. Melt the butter in a large saucepan over medium heat.
- Once the butter has melted, add your finely chopped onion. Cook and stir the onion until it turns lightly golden brown. This should take about 10 minutes.
- Sprinkle your flour over the cooked onions. Stir everything together until the onions are coated in the flour.
- Slowly pour your chicken broth and milk into the saucepan. Use a wire whisk to mix everything together, ensuring all the flour is dissolved.
- Bring your soup to a boil while stirring continuously. As soon as it thickens, reduce the heat to low.
- Stir in your dry sherry and the roasted cauliflower you set aside earlier.
- If you want a thicker consistency, you can blend half of the soup until smooth and then recombine it with the rest of the soup.
- Your Roasted Cauliflower Soup is now ready to serve. Enjoy it while it’s hot. For an additional touch, garnish with your favorite herbs or a sprinkle of cheese.

Can I Make Soup Recipe In A Slow Cooker Or Instant Pot?
You can adapt the Roasted Cauliflower Soup recipe for both a slow cooker and an Instant Pot.
Slow Cooker
- Follow the initial steps of the recipe, roasting the cauliflower in the oven and sautéing the onions in a pan.
- Transfer the roasted cauliflower and sautéed onions into the slow cooker. Add the spices, broth, and milk.
- Set the slow cooker on low for 6-8 hours or high for 3-4 hours.
- Stir in the sherry near the end of the cooking time.
- For a thicker soup, blend some of the soup and return it to the slow cooker before serving.
Instant Pot
- You can use the sauté function to cook the onions directly in the Instant Pot.
- Still, roast the cauliflower in the oven for that caramelized flavor.
- Add the roasted cauliflower, spices, broth, and milk to the Instant Pot.
- Close the lid, set the valve to sealing, and cook on high pressure for 10 minutes.
- Quickly release the pressure, open the lid, and stir in the sherry.
- As in the slow cooker method, blend some of the soup for a thicker consistency if desired.
Can I Use Store Bought Broth, Or Should I Make My Own?
You can use either store-bought or homemade broth for your Roasted Cauliflower Soup. Both have their own advantages.
Store-Bought Broth
- Convenience: It’s ready to use, saving you time and effort.
- Consistency: You’ll get a consistent flavor every time you use it.
- Variety: It’s available in several types (e.g., chicken, beef, vegetable) and flavors.
Homemade Broth
- Flavor: You control the ingredients so that you can adjust the flavor to your liking.
- Healthier: Homemade broth typically has less sodium and no preservatives or additives.
- Cost-effective: You can make it from kitchen scraps like vegetable peelings and bones, reducing waste and saving money.
Can I Use Different Types Of Meat/Fish/Pasta/Vegetables For The Soup Recipe?
You can certainly customize the Roasted Cauliflower Soup recipe by adding other ingredients. However, keep in mind that adding different components can change the overall flavor profile of the soup.
- Meat: Shredded chicken, cooked bacon, or diced ham could be great additions for a non-vegetarian version of the soup.
- Fish: If you wish to add seafood, consider flaky white fish or even shrimp, but be mindful of their cooking times, as they cook faster than most meats.
- Pasta: Small pasta shapes like orzo or pastina could fill the soup more. Cook the pasta separately and add it at the end to avoid it becoming too soft.
- Vegetables: Feel free to add other vegetables. Root vegetables like carrots or parsnips would complement the cauliflower well. You could also add leafy greens like spinach or kale for added nutrition.

Success Tips – Tips And Tricks For Making Soup
Success Tips for Making Roasted Cauliflower Soup:

- Mise en Place: Gather and measure all your ingredients before you start. This ensures a smooth cooking process.
