10 Slow Cooker Mushroom Soup Recipes for Cozy Comfort

Exploring new recipes can be so fun and fulfilling, but finding the time to research and test out new recipes when you’re already juggling work, relationships, and yourself? It can be challenging to fit it all in. That’s why I’m a huge fan of instant pots and slow cookers. They’re perfect when you need to “set it and forget it.” You add all the ingredients (with maybe a bit of prep before) and let the slow cooker do its thing.

Mushrooms are great for slow cooker recipes because they can be cooked for a long time and will become more flavorful as they simmer alongside the other seasonings and ingredients. They also are great meat replacements and add a savory, umami flavor to broths.

We’ve gathered a list of unique and flavorful cozy soup recipes for you. Most of these recipes suggest using whole mushrooms but making it even simpler, feel free to try substituting canned mushrooms (we promise not to tell.) Here’s what you’ll need.

• Slow Cooker: The Duo Instant Pot is a slow cooker and instant pot all in one. You can get it in mini or full size if you cook for the whole family.
• Fresh mushrooms: Smallhold is an awesome mushroom operation that supplies grocery stores around the country.
• Dried mushrooms: Far West Fungi has some delicious family-grown options.

This wild mushroom soup recipe is deceptively simple, with only a few ingredients. The secret comes from a quick sauté of 3-4 different types of mushrooms on the stovetop before adding it to the slow cooker. While it takes a few extra minutes, giving this soup richness and depth is worth it.

Pro tip: Pair this with delicious cooked wild rice (bonus points if you use a rice cooker) for an even more filling meal

As the creator says, this thick and filling soup is genuinely a “dump and go” recipe. We love that this recipe has some ideas to save even more time, including buying precut ingredients and batching this soup to reheat later. If you want to add some thickness, a splash of heavy cream in your bowl would be lovely.
