Slow Cooker Gluten Free Mushroom Soup

Creamy gluten free mushroom soup that is made in your slow cooker, this delicious soup cooks while you are at work or school! (And don't worry, I include directions for making this recipe stovetop too!)

When is the last time you had a healthier gluten free mushroom soup? For me, it has been years. Canned soups are typically loaded with sodium. A few months ago my daughter posted a question on my Instagram asking what gluten free foods readers would like to see on my blog. Several people chimed in that they missed mushroom soup!

Why this soup is great:

This is a great dump-and-go slow cooker soup recipe. You can cook the onion and garlic ahead and then add it to the slow cooker, or just dump all of the ingredients into your Crock Pot if you are in a hurry. This soup slow cooks in the flavor all day and you can freeze the extras!

What mushrooms are best for soup?

You can use so many different mushroom types for this soup recipe. This time I used cremini mushrooms, but most white or brown mushrooms are all fine. Here are some more fun mushrooms for soup:

• Shiitake
• Lion's Mane
• Portabello

Ingredient notes:

• Mushrooms - As I mentioned above, you can get creative with the type of mushrooms you use, or use a combination.
• Heavy cream - this is great for adding creaminess to the soup.
• Onion - I love to use sweet onions for this recipe. Regular yellow onions also work well but I don't recommend red onions.
• Chicken broth - I use low sodium, but regular chicken broth or chicken bone broth also tastes good.
• White wine - You don't have to use expensive wine for cooking this recipe. Any cheap white table wine will do.
• Mushroom umami - I bought a bottle at Trader Joe's. Whole Foods and Amazon also carry this.

Recipe step by step directions:

Are you ready to give this easy slow cooker mushroom soup a try?

Making mushroom soup from scratch is simple! Although I list this as an optional step, I like to cook my onion and garlic slightly before adding it to my slow cooker. I feel like this gives a more caramelized flavor to the soup.

Step 1: In a sauté pan, add the oil, onion, and garlic. Cook on medium heat for 5 minutes.

Step 2: Add the onion and mushrooms to your slow cooker.

Step 3: Pour the rest of the liquid ingredients and seasonings in. Cover and set the slow cooker to cook.

If you want the soup sooner, cook on high for 4 hours. If you want this soup to cook while you are at work, cook on low for 7 hours.

Step 4: Add the starch! Lumps are such a pain when you are trying to thicken the soup. My best secret to avoid lumps is to put the thickener in a small bowl. Add ¼ cup hot soup broth and whisk quickly to blend. Add ¼ cup additional soup and whisk. Pour the mixture into your soup pot and mix well.

Ingredients

  

1x2x3x

• ▢ 2 cups mushrooms
• ▢ 2 cloves garlic minced
• ▢ 1 sweet onion chopped
• ▢ 4 tablespoons butter
• ▢ ½ cup heavy cream
• ▢ 4 cups low sodium chicken broth
• ▢ ½ cup white wine
• ▢ 2 teaspoons mushroom umami
• ▢ 2 teaspoons salt
• ▢ 3 teaspoons thyme
• ▢ ½ teaspoon black pepper
• ▢ ¼ cup tapioca starch for thickening!

Instructions

 

• In a pan, add the butter, onion, and garlic and cook on medium heat for 5 minutes.
• Add the onion mixture to your slow cooker and add the rest of the ingredients except the tapioca starch.
• Cover the slow cooker with a lid and set to cook on high for 4 hours or 6 hours on the low setting. Even better if your Crock Pot has a setting where it starts cooking on high and switches to low automatically.
• When the soup is done, garnish with sour cream, parsley, or thyme.

Notes

1. I bought the mushroom umami at Trader Joe's. If you can't find it, substitute with miso paste.
2. This soup will keep up to 4 days in an air-tight container, or up to 4 months in the freezer.

Stovetop Directions:

Add your oil and brown the onion and mushrooms like you would for the slow cooker version. Add the rest of the soup ingredients to the soup pot, cover, and simmer on low for 30 minutes. Add thickener and whisk to blend.
