Soup With Broccoli and Cauliflower

As soon as Fall comes around it marks the beginning of soup season. There’s just nothing better than enjoying a warm bowl of soup on a cold or rainy day.

This Fall I wanted to kick off soup season with a creamy, nourishing soup made with just a few simple ingredients: Broccoli and Cauliflower Soup. This soup is the perfect combination of healthy, hearty and delicious. Roasting the vegetables for this soup helps bring out their flavour and gives the soup a nice roasted caramelized taste. (Trust me, this extra step is totally worth it!)

This soup is a great go-to if you’re looking for a quick and easy recipe that doesn’t compromise on taste and can be prepared in advance. If you’re looking for a even creamier broccoli soup make sure to try this Vegan Cream of Broccoli Soup next!

How To Make Soup With Broccoli and Cauliflower

Step 1

Toss the broccoli and cauliflower florets with olive oil and place on a baking sheet lined with parchment paper. Roast in the oven at 425 degrees F for 15-20 minutes until lightly golden brown.

Step 2

Sautee the onions and garlic in a large pot on medium-high heat, then add the broccoli, cauliflower, herbs, seasoning and broth and bring everything to a boil, then cover and let simmer on low for 10 minutes.

Step 3

Use an immersion blender (or transfer the soup to a regular blender) and blend until smooth and creamy and serve.

Recipe Variations

  • Make it Broccoli and Cauliflower Cheese Soup: Stir in 1/2 cup of grated cheddar or Parmesan for a cheesy twist!
  • Boost the protein: If you want to make this soup high in protein add 1 cup of cooked white beans to the soup and blend.
  • Spice it up: Use any herbs and seasoning you like. I use Italian seasoning blend for this recipe but you could also use herbs de Provence, thyme, parsley, basil…etc.

How To Store And Reheat

This broccoli and cauliflower soup stores beautifully, making it a great option for meal prep!

  • Refrigerate: Store in an airtight container in the fridge for up to 4-5 days.
  • Freeze: Allow the soup to cool completely, then freeze it in freezer-safe containers for up to 3 months.
  • Reheat: For the best texture, reheat the soup on the stove over medium heat, stirring occasionally, until it’s heated through. You can also microwave it in short intervals, stirring in between, to ensure even heating.

Expert Tips For Making Broccoli and Cauliflower Soup

  • Roast the veggies: Roasting the broccoli and cauliflower before blending enhances their natural sweetness and adds more depth of flavor to the soup.
  • Make it creamy or chunky: For a chunkier soup, blend only half the mixture and leave the rest as is. For a smoother texture, blend the entire soup until creamy.
  • Season to taste: Don’t forget to adjust the seasoning at the end, depending on the brand of broth you use, you may need to add more or less salt and seasoning to the soup.
  • Garnish with toppings: Add croutons, a drizzle of olive oil, cream, or a sprinkle of Parmesan on top for extra flavor and texture.

Frequently Asked Questions

Can I make this soup without roasting the vegetables?

Yes, but roasting brings out more flavor. If you skip the roasting, simply add the broccoli and cauliflower florets to the pot with the rest of the ingredients and let simmer until the vegetables are tender.

How do I make this soup thicker?

You can reduce the amount of broth or add a starchy vegetable like potatoes to the mix.

What goes well with broccoli and cauliflower soup?

This soup pairs well with crusty bread, a light salad, or even a grilled cheese sandwich for a complete meal.
