What is Vegan Broccoli Potato Soup?

Vegan Broccoli Potato Soup is a creamy vegetable-based soup made with golden potatoes, broccoli florets, and raw cashews instead of dairy cream. The result? A naturally thick, satisfying bowl of comfort that tastes indulgent but stays 100% plant-powered.

The nutritional yeast gives it that nutty, “cheesy” undertone, while the potatoes add heartiness and the broccoli keeps things bright and wholesome. It’s kind of like a cross between a classic baked potato soup and broccoli cheddar—but with a healthy twist. If you’ve ever tried my Winter Minestrone Soup, you’ll recognize the same kind of cozy, one-pot magic here.

Reasons to Try Vegan Broccoli Potato Soup

First off, it’s dairy-free, gluten-free, and totally satisfying. But the real reason you’ll want this soup in your rotation is how easy it is. You can make it on a lazy Sunday afternoon or a chaotic Wednesday night and still feel like you cooked something special. It’s also a great way to sneak in extra veggies (hello, picky eaters!) without anyone noticing.

The cashews add body and richness, the potatoes thicken things naturally, and the broccoli brings a pop of green that makes the whole bowl feel fresh. Plus, it reheats beautifully, so you can make a big batch and enjoy it all week long.

Ingredients Needed to Make Vegan Broccoli Potato Soup

• ½ yellow onion (or ½ leek), chopped
• 4 cloves garlic, minced
• 2 lbs golden potatoes, scrubbed and diced
• 1 large carrot, diced
• 1 celery stick, chopped
• 1 cup raw cashews
• 7–8 cups low-sodium vegetable stock
• 5–6 tbsp nutritional yeast
• 1 lb broccoli florets
• 1 pinch sea salt, to taste
• 1 pinch red pepper flakes
• ⅓ cup fresh chives, snipped for garnish
• ½ tsp turmeric (optional, for color and anti-inflammatory boost)

For a lighter alternative, try swapping some of the potatoes for cauliflower—you can check out my Creamy Spinach and Potato Garden Soup for a similar creamy texture with a different flavor twist.

Instructions to Make Vegan Broccoli Potato Soup – Step by Step

Step 1: Sauté Your Aromatics

Start by preheating a heavy-bottomed stockpot over medium-low heat. Add a splash of water or a drizzle of olive oil, then toss in your chopped onion (or leek). Sauté until it turns translucent and fragrant—about 5 minutes. The goal here is to coax out the sweetness without browning. Add a pinch of salt and red pepper flakes for a little kick, followed by your diced carrots and celery. Give everything a quick stir, cover with a lid, and let it sweat for another 3–4 minutes until the carrots start to soften. This slow, gentle cooking is where flavor begins to build.

Step 2: Build the Base

Now comes the hearty part. Add your minced garlic, diced potatoes, and raw cashews directly into the pot. Pour in the vegetable stock, scraping the bottom of the pot to lift all those flavorful bits. Stir in the nutritional yeast—this will be your “cheesy” flavor bomb. Bring the soup to a gentle simmer, cover, and let it cook for about 20 minutes. You’ll know it’s ready when the potatoes and cashews are soft enough to mash easily with a fork.

Step 3: Blend Until Silky Smooth

Once everything’s tender, it’s time for the magic. Carefully transfer the soup in batches to a powerful blender (like a Vitamix). Blend on high until completely smooth and creamy. This step-by-step blending is what transforms a simple mix of veggies into something restaurant-worthy. If you’re using an immersion blender, take your time—it won’t get quite as velvety, but it’ll still taste fantastic. Pour the pureed soup back into the pot.

Step 4: Add the Broccoli

Return your pot to the stove and bring the soup back to a gentle simmer. Toss in the broccoli florets and cover with a lid. Cook for 3–5 minutes—just long enough to soften the broccoli without losing its bright green color. Overcooked broccoli turns dull, so keep an eye on it. Alternatively, you can steam the broccoli separately and add it in at the end if you prefer more texture.

Step 5: Taste, Adjust, and Serve

Give your soup a good stir and taste for seasoning. Add more salt, red pepper flakes, or even a splash of veggie stock if you prefer a thinner consistency. When you ladle it into bowls, finish each one with fresh chives and maybe a few extra red pepper flakes for color. Serve it piping hot with crusty bread or a sprinkle of Vegan Ranch Pasta Salad on the side if you’re feeling fancy.

Step 6: Bonus Tip for Cream Lovers

If you love extra creaminess, reserve a few spoonfuls of the blended soup before adding broccoli and drizzle it over the top before serving. It gives that “swirled café” effect that makes even weeknight dinners look special.

What to Serve with Vegan Broccoli Potato Soup

This soup pairs beautifully with simple sides like garlic toast, a crisp Greek Pasta Salad, or a light green salad. It’s hearty enough to be a main course, but if you’re feeding a crowd, serve it with roasted vegetables or a slice of Snickerdoodle Cobbler for dessert—you’ll thank me later.

Key Tips for Making Vegan Broccoli Potato Soup

1. Don’t skip the nutritional yeast. It gives that irresistible “cheesy” umami flavor that makes this soup feel indulgent.
2. Use a high-speed blender. This step makes or breaks the texture. A regular blender works, but a Vitamix or Blendtec takes it to silky perfection.
3. Add turmeric for a pop of golden color. It’s optional but adds depth and brightness.
4. Blend in batches safely. Hot soup expands—cover loosely and blend carefully.
5. Taste before serving. Potatoes can dull seasoning, so adjust salt and pepper at the end.
6. For meal prep: Divide into containers for easy grab-and-go lunches.

Storage and Reheating Tips for Vegan Broccoli Potato Soup

Store leftovers in an airtight container in the fridge for up to 4 days. To reheat, warm on the stovetop over medium heat, stirring occasionally. You can add a splash of vegetable stock or plant milk to bring back that creamy consistency. If you plan to freeze it, let the soup cool completely first, then portion into freezer-safe containers. It keeps beautifully for up to 3 months—just thaw overnight in the fridge before reheating.

FAQs

Can I make this without cashews?
Yes! Swap cashews for sunflower seeds or use a splash of coconut milk at the blending stage.

Can I use frozen broccoli?
Absolutely. Just add it directly into the simmering soup—no need to thaw.

Can I skip the nutritional yeast?
You can, but you’ll miss that lovely cheesy depth. Try adding a teaspoon of miso paste instead for umami richness.

What if I don’t have a blender?
Use a potato masher for a chunkier texture—it won’t be as creamy, but still delicious.

Can I make it ahead of time?
Definitely! In fact, the flavors deepen as it sits, so it’s even better the next day.
