Ingredients
Yields 4 hearty bowls of creamy broccoli cauliflower soup.
Vegetables
- 3 cups broccoli florets (fresh or frozen)
- 3 cups cauliflower florets
- 1 medium yellow onion, diced
- 2 garlic cloves, minced
- 1 medium carrot, diced — optional, adds natural sweetness
Liquids & Seasonings
- 4 cups low-sodium vegetable broth (or chicken broth)
- 1 cup water — adjust for desired thickness
- 1 tsp kosher salt (taste and adjust)
- ½ tsp freshly ground black pepper
- ¼ tsp ground nutmeg for gentle warmth
- ½ tsp dried thyme or 2 fresh sprigs
Creamy Base
- 1 cup coconut milk, whole milk, or heavy cream
- 1 ½ cups shredded sharp cheddar cheese, divided
- 1 Tbsp unsalted butter or olive oil
Optional Flavor Boosters
- ½ tsp smoked paprika for depth
- 2 Tbsp nutritional yeast (vegan “cheesy” note)
- 1 Tbsp fresh lemon juice to brighten
- 2 Tbsp chopped parsley or chives for garnish
- Crumbled bacon or roasted broccoli florets for a hearty topping
Instructions
Step1: Sauté the aromatics
Heat butter in a dutch oven over medium. Add diced onion and carrot; cook 4 minutes, stirring, until soft. Stir in garlic for 30 seconds to release aroma.
Step 2: Add the vegetables
Add the broccoli florets, cauliflower florets, thyme, salt, and pepper. Pour in the broth and 1 cup water. The liquid should just cover the mix; add more broth if needed.
Step3: Simmer until tender
Bring to a boil, then lower to a gentle bubble. Cover and cook 12–15 minutes, until broccoli and cauliflower are fork-soft.
Step 4: Blend the soup
Remove the pot from heat. Use an immersion blender to purée the mixture until velvety. Prefer texture? Blend only half, leaving small veggie bites. No stick blender? Carefully ladle the hot soup to a blender, vent the lid, purée, then return the soup to the pot.
Step 5: Create the creamy base
Return the pot to low heat. Stir in coconut milk or heavy cream plus 1¼ cups cheddar cheese. Let the dairy warm, then add the cheese gradually, stirring until melted. This step turns broth into smooth cheese soup with mild broccoli cheddar notes.
Step 6: Adjust thickness and flavor
Too thick? Whisk in extra broth a splash at a time. Too thin? Simmer 3 minutes to reduce. Taste the soup; add nutmeg, smoked paprika, or more salt to balance. A squeeze of lemon brightens creamy broccoli depth.
Step 7: Finish and serve
Ladle the creamy broccoli cauliflower soup into bowls. Top with the remaining cheddar, parsley, or roasted broccoli for crunch. Enjoy hot alongside crusty bread.
Instant Pot option: Sauté aromatics on Sauté mode, add veggies and 4 cups broth, seal, and cook 6 minutes on High. Quick-release, then use an immersion blender and follow Steps 5–6.
Pro Tips and Variations
Make This Soup Shine
– Soak cauliflower first. Submerge florets in cold, salted water for 10 minutes. This step lifts hidden grit and tames sulfur notes, giving a sweeter finish.
– Roast for deeper flavor. Spread broccoli and cauliflower on a sheet, drizzle oil, and roast at 425 °F for 15 minutes. Roasted broccoli and cauliflower caramelize, adding nutty depth to the creamy base.
– Use an immersion blender wisely. For silky texture, blend the soup until smooth. For a rustic bowl, puree only half, then stir the chunky half back in.
– Thicken the soup naturally. Simmer an extra five minutes uncovered, or mash one cooked potato into the pot. Both tricks keep the soup rich without extra cream.
– Balance seasoning last. Taste the soup before serving. A pinch of salt, a grind of pepper, or a squeeze of lemon can brighten heavy dairy and veggie tones.
Flavor Variations
– Cheesy Broccoli Cauliflower Soup
Stir in ½ cup grated Parmesan with the cheddar and top each bowl with extra shredded cheese. Friends who love a thick soup rave about this version.
– Vegan Creamy Broccoli Cauliflower Soup
Replace butter with olive oil, swap coconut milk for dairy cream, and fold in ¼ cup nutritional yeast or vegan cheese. The result stays velvety while remaining lactose-free.
– Spicy Southwest Twist
Add ½ tsp cumin and a pinch of chipotle powder when sautéing onion. Finish with roasted corn kernels and cilantro. The warmth complements the creamy broccoli notes.
– Herb Garden Version
Blend fresh parsley and chives with the soup, then garnish with a swirl of herb oil. These bright herbs cut through the richness for a lighter, healthy soup vibe.
Storage and Freezer Tips
– Cool, pack, and freeze this soup in individual containers for up to three months. Thaw overnight in the fridge and reheat on low, adding a splash of broth to loosen.
– Leftovers in the fridge stay fresh three days. Rewarm gently; high heat may cause cheese to separate.

FAQs
What to add to broccoli soup for flavor?
Sautéed onion and garlic build a flavorful base. A small pinch of nutmeg or smoked paprika deepens taste. Sharp cheddar or Parmesan lends a savory kick, while a squeeze of lemon at the end brightens the whole bowl.
Why do you soak cauliflower before cooking?
A short soak in cold, salted water dislodges grit and softens strong sulfur notes. The florets taste cleaner and sweeter once simmered in the soup.

Thyme, parsley, and chives pair nicely. Thyme simmers with the broth for earthiness; fresh parsley or chives sprinkled on top add a bright, fresh finish.
How to reduce bitterness in broccoli soup?
Quickly blanch or roast the florets before adding them to the pot. A splash of lemon juice or extra salt also balances mild bitterness without masking veggie flavor.
How do you thicken broccoli soup?
Simmer uncovered to reduce liquid, or blend part of the vegetables into the broth. For extra body, stir in a spoonful of mashed potato or a touch of heavy cream.
Why is my cauliflower soup bland?
It likely needs more salt, acid, or fat. Taste and adjust with sea salt, a squeeze of lemon, or a little cheese. Roasting the cauliflower first also intensifies flavor.How long to roast cauliflower for soup?
Cut florets into bite-size pieces, toss with olive oil, and roast at 425 °F (220 °C) for 15–20 minutes. Edges should brown lightly; this caramelization boosts depth in the finished soup.
