Servings 4

1 tablespoon olive oil
1 medium onion, finely chopped
3 cloves garlic, minced
12 ounces cremini or white mushrooms, sliced
4 cups fresh spinach, loosely packed
8 ounces egg-free pasta (such as penne or fusilli)
3 cups vegetable broth, low sodium
1/2 cup raw cashews (soaked in hot water for 15 minutes)
2 tablespoons tomato paste
1 tablespoon soy sauce or tamari (gluten-free if needed)
1 teaspoon smoked paprika
1/2 teaspoon dried thyme
1/4 teaspoon black pepper
1/4 teaspoon salt, or to taste
2 tablespoons lemon juice
Fresh parsley, chopped (for garnish)

Ingredients for One-Pot Creamy Mushroom and Spinach Stroganoff

Instructions

Drain the soaked cashews and add them to a blender with 1/2 cup vegetable broth. Blend until completely smooth and creamy. Set aside.
Heat the olive oil in a large deep skillet or wide pot over medium heat.
Add the chopped onion and cook, stirring frequently, until softened and translucent, about 4-5 minutes.
Add the minced garlic and cook for another 30 seconds until fragrant.
Add the sliced mushrooms to the pot and cook until they release their moisture and begin to brown, about 6-8 minutes, stirring occasionally.
Stir in the tomato paste, smoked paprika, dried thyme, salt, and black pepper; cook for 1 minute to combine flavors.
Add the pasta, remaining vegetable broth (2 1/2 cups), soy sauce, and the creamy cashew mixture. Stir to combine all ingredients evenly.
Bring the mixture to a boil, then reduce heat to a simmer. Cover and cook for 12-15 minutes, stirring occasionally, until the pasta is al dente and most of the liquid is absorbed.
In the last 3 minutes of cooking, stir in the fresh spinach leaves until wilted and incorporated into the sauce.
Remove the pot from heat and stir in the lemon juice for brightness.
Taste and adjust seasoning with additional salt or pepper if needed.
Serve warm, garnished with chopped fresh parsley. Enjoy leftovers refrigerated up to 3 days.
