This rich and velvety soup uses raw cashews and nutritional yeast to create a deep, cheesy flavor without any dairy. It is a hearty, plant-based meal that combines fresh garden vegetables with a smooth, creamy base.

List of ingredients

1/2 yellow onion or 1/2 leek, chopped – provides a savory aromatic base.
4 cloves garlic, minced – adds pungent depth to the broth.
2 lb golden potatoes, scrubbed, rinsed and diced – creates a naturally thick texture.
1 large carrot, diced – adds subtle sweetness and color.
1 celery stick, chopped – contributes a classic savory element.
1 cup raw cashews – ensures a rich, creamy consistency after blending.
7-8 cups low sodium vegetable stock – the primary liquid for simmering.
5-6 tbsp nutritional yeast – provides a savory, cheddar-like taste.
1 lb broccoli florets – the main vegetable component.
1 pinch sea salt, to taste – enhances the overall flavor profile.
1 pinch red pepper flakes – adds a subtle hint of warmth.
1/3 cup fresh chives, snipped – used for a bright, fresh garnish.
1/2 tsp turmeric, optional – gives the soup a vibrant golden hue.

step-by-step instructions

Sauté the Aromatics: Heat a heavy stock pot over medium-low heat. Sauté the chopped onion in a splash of water or a drizzle of olive oil until it becomes translucent.
Sweat the Vegetables: Add the sea salt, red pepper flakes, celery, and carrots to the pot. Cover with a lid and cook for a few minutes until the carrots begin to soften.
Simmer the Base: Stir in the minced garlic, diced potatoes, raw cashews, and vegetable stock. Add the nutritional yeast, cover the pot, and simmer for 20 minutes or until the potatoes and cashews are completely softened.
Blend the Soup: Carefully transfer the mixture to a high-power blender. Purée the ingredients until the texture is silky smooth.
Cook the Broccoli: Return the puréed soup to the pot and bring it back to a simmer. Add the broccoli florets, cover, and cook for 3 to 5 minutes until the broccoli is tender but still holds its shape.
Final Adjustments: Taste the soup and adjust the seasoning with additional sea salt. If the soup is too thick, stir in more vegetable stock until you reach your preferred consistency.
Serve: Ladle the hot soup into bowls. Garnish with fresh chives and an extra pinch of red pepper flakes.

Optimizing Vegetable Selection

Selecting the Right Potato Variety

Golden potatoes are ideal for this recipe because they have a medium starch content and a buttery flavor. They break down easily during the blending process, which contributes to the creamy texture without making the soup too gummy. If you use Russet potatoes, the soup will be significantly thicker and have a more floury consistency.

Preparing Fresh Broccoli Florets

Cut the broccoli into small, uniform pieces to ensure they cook evenly during the final simmer. To avoid a mushy texture, only add the florets once the base is already blended and hot. Cooking them for only 3 to 5 minutes preserves their bright green color and an al dente bite.

Achieving the Perfect Creamy Consistency

Integrating Raw Cashews for Richness

Raw cashews provide the healthy fats and proteins necessary to mimic the mouthfeel of heavy cream. There is no need to soak them in advance, as the 20-minute simmering process softens them sufficiently for blending. Ensure you use raw, unsalted cashews to maintain control over the sodium levels of the soup.

Utilizing a High-Speed Blender

A high-power blender is essential for achieving a professional, silky smooth texture, especially when processing cashews and potatoes. While an immersion blender can be used, it may leave small grains of cashew or potato. For the smoothest result, blend in batches and vent the lid to allow steam to escape.

Flavor Enhancements and Variations

Increasing the Heat Level

The red pepper flakes provide a mild warmth, but you can increase the spice by adding a pinch of cayenne pepper or a dash of hot sauce. For a different kind of heat, stir in some smoked paprika during the sautéing phase. This adds a woody, smoky depth that complements the nutritional yeast.

Experimenting with Other Root Vegetables

While golden potatoes are recommended, you can substitute some of the potato volume with parsnips or turnips. Parsnips add a slightly peppery and sweet flavor that pairs well with broccoli. Always maintain at least one pound of potato to ensure the soup retains its signature thickness.

Serving and Presentation Ideas

Pairing with Crusty Breads

This soup pairs exceptionally well with a side of toasted sourdough or warm focaccia. The acidity of sourdough cuts through the richness of the cashew cream. Serve the bread with a side of vegan garlic butter for an enhanced dining experience.

Adding Fresh Herbal Garnishes

Fresh chives are the traditional garnish for this dish, providing a mild onion flavor and a pop of color. You can also use thinly sliced green onions or a sprinkle of fresh parsley. For an earthy touch, a small amount of fresh thyme added during the simmering stage works well.

Storage and Preservation Methods

Refrigeration and Shelf Life

Store the leftover soup in an airtight container in the refrigerator for up to five days. Because of the cashew and potato content, the soup will thicken significantly as it cools. This is normal and can be easily corrected during the reheating process.

Freezing for Long-Term Storage

This soup freezes well for up to three months. Pour the cooled soup into freezer-safe bags or containers, leaving a small amount of space at the top for expansion. To prevent the broccoli from becoming too soft upon thawing, you may choose to freeze the blended base separately from the florets.

Effective Reheating Strategies

Stovetop Reheating Method

Reheat the soup slowly over medium-low heat on the stove. Stir frequently to prevent the bottom from scorching, as the starch in the potatoes can stick to the pan. Add a splash of vegetable stock or water to loosen the texture as it warms up.

Microwave Heating Tips

If using a microwave, heat the soup in short 1-minute intervals. Stir the soup thoroughly between each interval to ensure an even distribution of heat. This prevents hot spots and ensures the cashew cream doesn’t separate.

Common Cooking Troubleshooting

Fixing a Soup That Is Too Thick

If the soup becomes too dense after blending or reheating, gradually stir in additional low-sodium vegetable stock. Add the liquid one-quarter cup at a time until the desired consistency is reached. Avoid adding too much at once, or you may dilute the cheesy flavor of the nutritional yeast.

Preventing Overcooked Broccoli

To prevent the broccoli from turning an olive-brown color, avoid boiling it for too long. If you are preparing the soup in a large batch, consider steaming the broccoli separately and adding it to individual bowls. This ensures every serving has perfectly textured vegetables.

Frequently Asked Questions

Can I use frozen broccoli?

Yes, you can use frozen broccoli florets. Add them during the final simmer, but reduce the cooking time by 1-2 minutes since frozen vegetables often soften faster than fresh ones.

How do I make this recipe nut-free?

To make this soup nut-free, replace the raw cashews with an equal amount of sunflower seeds or a can of full-fat coconut milk. Sunflower seeds provide a similar creaminess, though they have a slightly more toasted flavor.

Which blender is best for this soup?

A high-speed blender like a Vitamix or Blendtec is best for pulverizing the cashews into a smooth cream. If you only have a standard blender, you may need to blend for a longer period or strain the soup through a fine-mesh sieve.

Can I substitute the vegetable stock?

You can use water combined with a vegetable bouillon cube or a light vegetable broth. Ensure the substitute is low in sodium to prevent the soup from becoming overly salty after the simmering and reduction process.
