This hearty vegan mushroom and kale soup is perfect for a cozy night in. Packed with nutritious kale and savory mushrooms, this soup is both delicious and nourishing. It's a simple yet flavorful dish that will warm you up from the inside out.
If you don't usually stock kale or mushrooms in your kitchen, you'll need to pick these up at the supermarket. Kale is a leafy green vegetable that's often found in the produce section, while mushrooms can usually be found near other fresh vegetables. Make sure to get fresh, not canned, for the best flavor.

Ingredients for Vegan Mushroom and Kale Soup
Olive oil: Used for sautéing the vegetables, adding a rich flavor and healthy fats.
Onion: Provides a sweet and savory base for the soup.
Garlic: Adds a pungent and aromatic flavor to the dish.
Mushrooms: Brings an earthy and umami taste to the soup.
Kale: A nutrient-dense leafy green that adds texture and color.
Vegetable broth: Forms the liquid base of the soup, enhancing the overall flavor.
Salt: Enhances the flavors of all the ingredients.
Black pepper: Adds a hint of spice and depth to the soup.
Technique Tip for This Soup
When cooking the mushrooms, make sure to spread them out in an even layer in the pot. This allows them to brown properly rather than steam. Avoid overcrowding the pot, as this will prevent the mushrooms from achieving that rich, caramelized flavor. If necessary, cook them in batches.

How to Store or Freeze This Soup
- Allow the soup to cool to room temperature before storing. This helps prevent condensation, which can lead to a watery texture and spoilage.
- Transfer the vegan mushroom and kale soup into airtight containers. Glass containers with tight-fitting lids are ideal as they do not absorb odors and are easy to clean.
- Label each container with the date of preparation. This ensures you keep track of freshness and consume the soup within a safe timeframe.
- Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. The cool temperature will keep the vegetables fresh and the flavors intact.
- For longer storage, place the airtight 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. This gradual thawing helps maintain the texture and flavor of the mushrooms and kale.
- Reheat the soup on the stovetop over medium heat, stirring occasionally to ensure even heating. Avoid boiling, as this can cause the vegetables to become mushy.
- If reheating in the microwave, use a microwave-safe container and heat in short intervals, stirring in between to distribute the heat evenly.
- Adjust the seasoning after reheating, as the flavors may mellow during storage. A pinch of salt or a dash of black pepper can revive the taste.
- Enjoy your reheated vegan mushroom and kale soup with a slice of crusty bread or a fresh salad for a complete meal.
How to Reheat Leftovers

Microwave method: Transfer the soup to a microwave-safe bowl. Cover with a microwave-safe lid or a plate. Heat on high for 2-3 minutes, stirring halfway through. Continue heating in 1-minute intervals until the soup is hot throughout.
Double boiler method: Place the soup in a heatproof bowl and set it over a pot of simmering water. Stir occasionally until the soup is heated through. This method helps to avoid scorching and maintains the soup's texture.
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 20-25 minutes, or until the soup is hot throughout. Stir halfway through to ensure even heating.
Slow cooker method: Transfer the soup to a slow cooker and set it to low. Heat for 1-2 hours, stirring occasionally, until the soup is thoroughly warmed. This method is great for keeping the soup warm for extended periods.
