This vegan mushroom and kale soup is a hearty and nutritious dish perfect for any season. Packed with earthy mushrooms and vibrant kale, this soup is both comforting and wholesome. It's easy to prepare and makes for a satisfying meal that even non-vegans will love.
If you don't usually stock kale or mushrooms in your kitchen, you might need to make a trip to the supermarket. Kale is a leafy green vegetable that's rich in vitamins and minerals, while mushrooms add a savory depth to the soup. Both ingredients can typically be found in the produce section.

Ingredients for Vegan Mushroom and Kale Soup
Olive oil: Used for sautéing the vegetables and adding a rich flavor.
Onion: Adds a sweet and savory base to the soup.
Garlic: Provides a pungent and aromatic flavor.
Mushrooms: Adds an earthy and umami taste to the soup.
Vegetable broth: Forms the liquid base of the soup, adding depth and flavor.
Kale: Adds a nutritious and slightly bitter element to the soup.
Salt: Enhances the overall flavor of the soup.

Technique Tip for This Recipe
When cooking the onion and garlic, make sure to keep the heat at medium to avoid burning. Burnt garlic can impart a bitter taste to the soup. Stir frequently to ensure even cooking. When adding the mushrooms, give them enough time to release their juices and develop a rich, umami flavor. This step is crucial for deepening the overall taste of the soup. For the kale, remove the tough stems before chopping to ensure a tender texture in the final dish.

How to Store or Freeze This Soup
- Allow the soup to cool completely before storing. This helps prevent condensation, which can lead to a watery texture.
- Transfer the cooled soup into airtight containers. Glass containers with tight-fitting lids are ideal for maintaining freshness.
- Label the containers with the date to keep track of how long the soup has been stored.
- Store the soup in the refrigerator if you plan to consume it within 3-4 days. This ensures the vegetables and broth retain their flavors and textures.
- For longer storage, place the containers in the freezer. The soup can be frozen for up to 3 months without losing its quality.
- When ready to reheat, thaw the soup in the refrigerator overnight if frozen. This gradual thawing helps maintain the integrity of the kale and mushrooms.
- Reheat the soup on the stovetop over medium heat, stirring occasionally to ensure even heating. Avoid boiling, as this can make the kale overly soft.
- If reheating in the microwave, use a microwave-safe container and heat in short intervals, stirring in between to distribute the heat evenly.
- Add a splash of vegetable broth or water if the soup appears too thick after reheating. This helps restore its original consistency.
- Garnish with fresh herbs or a drizzle of olive oil before serving to enhance the flavor and presentation.
How to Reheat Leftovers
Stovetop method: Pour the leftover soup into a pot. Heat over medium heat, stirring occasionally, until the soup is thoroughly heated. This method helps maintain the texture of the mushrooms and kale.
Microwave method: Transfer the soup to a microwave-safe bowl. Cover with a microwave-safe lid or a microwave-safe plate to prevent splatters. Heat on high for 2-3 minutes, stirring halfway through to ensure even heating. Adjust the time as needed depending on your microwave's power.
Double boiler method: Place the soup in a heatproof bowl. Set the bowl over a pot of simmering water, ensuring the bottom of the bowl does not touch the water. Stir occasionally until the soup is heated through. This gentle method helps preserve the flavors and textures.
Slow cooker method: Pour the leftover soup into a slow cooker. Set it to low heat and let it warm up for about 1-2 hours. This method is perfect if you have time and want to keep the soup warm for an extended period.
Oven method: Preheat your oven to 350°F (175°C). Pour the soup into an oven-safe dish and cover with foil. Heat for about 20-30 minutes, stirring halfway through to ensure even heating. This method is useful if you are reheating a large quantity.
