How to Make Vegan Potato Mushroom Soup

1. Heat the Oil: Begin by heating a large pot over medium-high heat. Add 2 tablespoons of avocado or olive oil to the pot, letting it warm up for a minute.

2. Saut the Aromatics: Add the 8 ounces of sliced cremini mushrooms and 1/2 medium diced yellow onion. Saut them for 5-6 minutes until softened and fragrant, then stir in 4 minced garlic cloves for an additional minute.

3. Coat with Flour: Sprinkle 1/4 cup of all-purpose flour over the veggies in the pot. Pour in 1/4 cup of vegetable broth to deglaze the pan, scraping all those tasty bits from the bottom.

4. Mix Creamy Base: In a separate bowl, whisk 1 tablespoon of cornstarch into 2 cups of chosen plant milk until lump-free. Add this mixture, 4 diced gold potatoes, the remaining vegetable broth (about 3 cups), and seasoning to the pot.

5. Simmer the Soup: Bring the soup to a vigorous boil, then lower the heat to medium-low. Cover the pot and let it simmer for 20-30 minutes, stirring occasionally, until the potatoes are tender.

6. Finish with Greens: Once cooked, turn off the heat and stir in 1 cup of chopped baby spinach or kale. Garnish with crushed red pepper flakes and fresh herbs if desired.

Optional: Serve with crusty bread for a comforting meal.
