Can You Vary Roasted Cauliflower Soup Recipe With Other Ingredients?

The Roasted Cauliflower Soup recipe can be adjusted to cater to different dietary needs:

Vegan: Substitute the butter with olive oil or vegan butter. Use vegetable broth instead of chicken broth. Replace milk with non-dairy milk like almond or coconut milk.
Vegetarian: Replace the chicken broth with vegetable broth.
Gluten-Free: Replace the all-purpose flour with a gluten-free alternative like cornstarch or a gluten-free flour blend.
Paleo: Replace the butter with ghee, the all-purpose flour with arrowroot powder, and the milk with almond milk or coconut milk.
Keto: Leave out the flour entirely or replace it with a keto-friendly thickener like xanthan gum. Use a low-carb milk alternative like almond milk.
Whole30: Substitute the butter with ghee. Replace flour with arrowroot powder and use Whole30-compliant chicken broth and non-dairy milk like almond or coconut milk.

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.

How To Serve?

Serving the Roasted Cauliflower Soup recipe at its best involves a few simple steps:

Serve Hot: The soup tastes best when served hot. Reheat it on the stovetop if necessary before serving.
Garnish: Add your chosen garnishes just before serving to keep them fresh and vibrant.

Presentation: Serve the soup in warm bowls to help it stay hot longer. Using a ladle ensures even distribution of both broth and chunks.
Additional Seasoning: Provide extra seasonings like black pepper, red pepper flakes, or herbs at the table so that each person can adjust the flavor to their liking.

Perfect Side Dishes

Crusty Bread: A simple, warm loaf of crusty bread pairs well with this soup, perfect for dipping and soaking up all the flavors.
Grilled Cheese Sandwich: For a comforting meal, serve the soup with a classic grilled cheese sandwich.
Green Salad: A fresh green salad with a light vinaigrette dressing adds a crisp contrast to the creamy soup.

Make Ahead: Prepare the soup as directed, including roasting the cauliflower and blending the ingredients. Let the soup cool to room temperature, then store it in the refrigerator for up to 2 days. When ready to serve, reheat the soup on the stove and adjust the seasoning if necessary.

What Can We Do With Leftovers?

Next-Day Lunch/Dinner: Reheat and serve as is for a quick and easy meal.
Base for a Casserole: Use the soup as a flavorful base for a vegetable casserole.

Make a Bread Bowl: Serve the soup in a hollowed-out bread bowl for a fun and hearty meal.

TIPS

Choose the Right Squash: Look for butternut squash that is firm, heavy for its size, and has a matte skin without any blemishes or soft spots. This ensures freshness and optimal flavor.
Roasting for Depth of Flavor: Consider roasting the butternut squash before adding it to the soup. Roasting caramelizes the natural sugars in the squash, enhancing its sweetness and adding depth of flavor to the soup.
Variety of Spices: Experiment with different spices to add complexity to your soup. Common spices that pair well with butternut squash include cinnamon, nutmeg, ginger, and cloves. Add them sparingly at first and adjust to taste.
Balance Sweetness with Acid: Butternut squash can be quite sweet, so balancing the sweetness with a touch of acid can elevate the flavors. A splash of apple cider vinegar or a squeeze of fresh lemon juice towards the end of cooking can help brighten the soup.
Creamy Texture: For a creamy texture without adding cream, consider incorporating coconut milk or cashew cream instead. These dairy-free alternatives lend richness and silkiness to the soup while keeping it vegan-friendly.
Layer Flavors: Build layers of flavor by sautéing aromatics like onions, garlic, and shallots before adding the squash and broth. This step enhances the depth of the soup’s flavor profile.
