There are soups that warm you and there are soups like this Vegan Comforting Broccoli Cheddar Soup — the kind that comes out of the pot so thick, so deeply golden, and so richly flavored with sharp cheddar and sweet broccoli that it is genuinely difficult to believe there is not a single drop of dairy in it. This is that soup. The one that delivers every quality that makes broccoli cheddar soup so universally beloved — the silky, velvety base, the tender chunks of broccoli and carrot, the sharp, savory cheese flavor that runs through every spoonful — and does it completely from plants, in under 40 minutes, in a single pot. The one that makes people ask for the recipe before they have finished their first bowl. The one that proves, beyond any doubt, that comfort food does not require dairy to be genuinely, deeply comforting.
The cheddar flavor in this soup comes from a combination of nutritional yeast, white miso paste, apple cider vinegar, and smoked paprika — four ingredients that together create the sharp, savory, slightly tangy profile of a good cheddar without any animal products. The creamy base is built from blended cashews and potato, which thicken the broth into something luxuriously silky while adding their own mild, buttery flavor. Shredded vegan cheddar is stirred in at the end for extra richness and the stretchy, melted cheese texture that is impossible to replicate with nutritional yeast alone.
What makes this soup so outstanding is the two-texture technique — blending half the soup smooth while leaving the other half chunky, so every bowl has both the silky, velvety base and the satisfying, tender bite of whole broccoli florets and carrot pieces. It is the best of both a bisque and a chunky vegetable soup, in one bowl.
This recipe is 100% vegan, naturally dairy-free, ready in under 40 minutes, and the kind of soup that belongs in the regular rotation from the first cold day of the year to the last.

Ingredients
For the Soup
- 1 large head broccoli (about 500g), cut into small florets and stem diced
- 2 medium carrots, peeled and finely diced
- 1 medium yellow onion, finely diced
- 4 cloves garlic, minced
- 1 medium Yukon Gold potato, peeled and diced
- 2 tbsp vegan butter or olive oil
- 1 litre (4 cups) vegetable broth
- 240ml (1 cup) unsweetened oat milk or other plant milk
For the Cheddar Flavor Base
- 70g (½ cup) raw cashews, soaked in hot water for 20 minutes and drained
- 4 tbsp nutritional yeast
- 1 tbsp white miso paste
- 1 tbsp apple cider vinegar
- 1 tsp smoked paprika
- ½ tsp turmeric (for color)
- ½ tsp mustard powder
- Salt and black pepper to taste
For Extra Cheesiness
- 100g (1 cup) vegan cheddar, shredded
- 1 tbsp cornstarch
To Serve
- Extra shredded vegan cheddar
- Toasted bread croutons or crusty bread
- Pinch of smoked paprika
- Fresh chives or parsley
- Cracked black pepper
Instructions
- Sauté the aromatics. Melt the vegan butter in a large pot over medium heat. Add the diced onion and cook for 4–5 minutes until soft and translucent. Add the garlic and cook for 1 minute until fragrant.
- Add vegetables and broth. Add the diced carrot, potato, and broccoli stems (reserve the florets for later) to the pot. Pour in the vegetable broth and oat milk. Bring to a boil, then reduce to a simmer and cook for 12–15 minutes until the potato and carrot are completely tender.
- Make the cheddar base. While the vegetables simmer, blend the drained cashews, nutritional yeast, miso paste, apple cider vinegar, smoked paprika, turmeric, mustard powder, and 120ml (½ cup) of the hot soup broth in a high-speed blender until completely smooth. Set aside.
- Add broccoli florets. Add the reserved broccoli florets to the pot and simmer for 5 minutes until just tender but still bright green.
- Blend half the soup. Using a ladle, transfer roughly half of the soup to the blender and blend until completely smooth. Return to the pot with the remaining chunky soup and stir to combine. This creates the signature two-texture result — silky and chunky in every bowl.
- Add the cheddar base. Pour the blended cashew cheddar base into the soup and stir until fully incorporated. Toss the shredded vegan cheddar with the cornstarch, then stir into the soup over low heat until melted and the soup is glossy and thick. Season generously with salt and pepper.
- Serve. Ladle into bowls and top with extra shredded vegan cheddar, a pinch of smoked paprika, fresh chives, and cracked black pepper. Serve with crusty bread or croutons.
Pro Tips
- Soak the cashews first. Even 20 minutes in hot water makes a significant difference to how smoothly the cashews blend — unsoaked cashews can leave small grains that make the soup slightly gritty rather than perfectly smooth.
- Toss the shredded vegan cheddar in cornstarch before adding. The cornstarch helps the vegan cheese melt smoothly and evenly into the soup without clumping or separating, producing a glossier, more stable result.
- Blend half, not all. Fully blended broccoli cheddar soup loses the textural contrast that makes the dish so satisfying. The half-blend technique gives you the creamiest possible base while preserving whole florets throughout.
- Add turmeric for the right color. Nutritional yeast alone produces a pale, beige soup. A small amount of turmeric gives it the deep golden-yellow color that is visually associated with a great cheddar soup and makes it far more appetizing.
Why Nutritional Yeast Tastes Like Cheese
Nutritional yeast is a deactivated yeast — Saccharomyces cerevisiae grown on a medium of molasses, then harvested, heated to deactivate it, and dried — and its remarkable ability to mimic the flavor profile of aged cheese is not accidental but chemical. The primary flavor compounds in nutritional yeast are glutamates — naturally occurring amino acids produced during the yeast’s fermentation and growth — specifically glutamic acid, which is one of the most powerful umami-generating compounds in the natural world and is the same compound responsible for the savory depth of aged parmesan, miso paste, soy sauce, and mushrooms. Nutritional yeast also contains a range of sulfur-containing compounds produced during the yeast’s metabolic processes that are closely related to the sulfur compounds produced during cheese aging — the same family of molecules responsible for the sharp, slightly pungent character of aged cheddar. Combined with the acid from apple cider vinegar (which mimics the lactic acid produced by cheese-making bacteria), the fermented depth of white miso, and the smoky dimension of paprika, nutritional yeast becomes the foundation of a flavor profile that is unmistakably, satisfyingly cheese-like — entirely from plants.
Flavor Variations
- Spicy Jalapeño Broccoli Cheddar Soup: Add 1–2 finely diced jalapeños with the onion and stir in a teaspoon of hot sauce with the cheddar base for a warmly spiced version.
- Broccoli Cheddar Soup with White Beans: Add a drained can of cannellini beans with the broccoli florets for extra protein and a creamier, heartier soup.
- Smoky Bacon Broccoli Cheddar Soup: Add 80g of diced smoked tempeh sautéed until crispy as a topping for a smoky, bacon-inspired finish.

Storage
- Refrigerator: Store in a sealed container for up to 5 days. The soup thickens considerably as it sits — add a splash of broth or oat milk and stir well when reheating.
- Freezer: Freeze the soup before adding the shredded vegan cheddar for up to 3 months. Thaw overnight in the refrigerator, reheat gently, and stir in fresh shredded vegan cheddar just before serving.
- Reheat: Reheat over low-medium heat, stirring frequently, to prevent the cheese from sticking to the bottom of the pot.
Frequently Asked Questions
Can I make this nut-free?
Yes — replace the cashews with 1 cup of diced and boiled potato, blended smooth with the same seasonings. The result is slightly less rich but still very creamy and completely nut-free.
What vegan cheddar brand melts best in soup?
Violife and Daiya shredded cheddars melt most reliably in soups. Always toss the shredded cheese in cornstarch before adding to hot liquid for the smoothest result regardless of brand.
Can I use frozen broccoli?
Yes — frozen broccoli florets work well. Add directly from frozen in Step 4 and simmer for 6–7 minutes rather than 5.
My soup is too thick. How do I fix it?
Add warm vegetable broth or oat milk a splash at a time until the consistency is right, stirring well between additions.
