Why go organic?

You may be wondering why I push organic ingredients for everything, even savory and healthy dishes. Organic ingredients go beyond just health and wellness, and contribute so much to the taste and flavor of a recipe. So, if you think that you're making something healthy and buying fruits, veggies, or meats so maybe you don't need to spend the extra to go organic here – let me sway your thinking.

Organic ingredients are made in a more pure way, therefore using no additives, no GMOs, and minimal ingredients. This really allows the true ingredients to shine – and because of that their flavor shines through. Therefore, organic ingredients are more flavorful than their non organic counterparts. So, just because it's already a healthy recipe, or you're already buying good for you ingredients – it doesn't mean you can skip organic! Trust me here, and make the switch. Your body and your taste buds will thank you!

So, I highly recommend that you buy the best organic ingredients for this recipe! You can also shop my Amazon Storefront for all my favorite organic ingredients here. Tip – hover over each ingredient to see the name. And if you want to learn more about organic foods and the difference, read my post here on Food Labels and What They Mean.

From Scratch Cream of Mushroom Soup

Recipe by MimiDifficulty: Easy



From scratch Cream of Mushroom Soup makes an amazing lunch, or you can use it in recipes like Green Bean Casserole!


  • 2 tablespoons organic salted butter

  • 1/2 organic yellow onion, roughly chopped

  • 8 ounces organic mushrooms, sliced

  • 4 cups organic vegetable stock

  • 2 cups organic milk

  • 1 cup organic heavy whipping cream

  • 1 teaspoon organic thyme

  • 1 teaspoon organic oregano

  • 1/2 teaspoon organic sage

  • 1/2 teaspoon organic black pepper

  • 1/4 teaspoon organic garlic powder

  • 1/4 teaspoon organic celery salt

  • 32 grams (1/4 cup) organic all purpose flour

  • 1 tablespoon organic cornstarch


  • In a large skillet, add the butter, onions, and mushrooms. Cook over medium/high heat and sauté until the onions are translucent and the mushrooms are fully cooked, about 5 minutes. Remove from heat.
  • Add vegetable stock, milk, heavy whipping cream, thyme, oregano, sage, black pepper, garlic powder, and celery salt to a 6-quart pot. Heat on medium until combined and warm, about 5 minutes
  • Remove 1 cup of the liquid and add it to a small saucepan. Bring it to a simmer over medium-low heat. Slowly add the flour while whisking. Simmer while whisking constantly until you have a smooth and thick roux. Remove from heat and add back to the milk mixture. Stir to combine.
  • Add the mushrooms mixture to the soup and bring to a boil. Whisk in the cornstarch until completely combined. Reduce heat and simmer, stirring frequently, until the mixture is creamy and coats the back of a spoon, about 10 to 20 minutes.
  • Using an immersion blender (or high powdered blender) blend soup to combine the mushrooms and onions completely, or leave small chunks if you prefer.
  • Serve immediately, or store in an airtight container in the fridge for up to 5 days.


  • High Altitude – Follow the recipe as noted.
