Wholesome Ingredients for This Gluten-Free Cream of Mushroom Soup

This recipe relies on fresh, nutrient-dense ingredients to achieve its flavor and creaminess without resorting to heavy fillers. Here are the key players:

Mushrooms: A low-calorie, fiber-rich ingredient full of umami flavor. We recommend white button mushrooms or creminis for a classic taste, but any variety works. Feel free to finely chop them for a smoother soup or leave them chunkier for more texture.
Gluten-Free All-Purpose Flour: This creates the velvety texture of the soup. Brands like Pillsbury Gluten-Free work perfectly! Coconut or almond flour can work in smaller quantities for a keto version (adjust liquid ratio).
Butter or Plant-Based Butter: Adds richness to the soup base. Options like Smart Balance or Earth Balance work great if keeping it dairy-free.
Milk or Dairy-Free Milk: For creaminess, choose unsweetened almond, oat, or cashew milk to keep it light while vegan-friendly.
