Mushroom Bean Soup

This meat-free Mushroom Bean Soup is hearty, healthy and packed with flavor. Even better, you can make it on the stove, in a slow cooker, or using an Instant Pot and it can be a freezer meal.

During the cooler months, we love hearty soups like Tuscan white bean soup, vegetarian pasta fagioli and minestrone soup!

My mom used to make this mushroom bean soup for years. Her trick is to add a can of organic cream of mushroom soup and grate carrots very finely, so the soup gets a nice yellow color.

If you love mushrooms, this is the best bean and mushroom soup to cozy up to this winter. It’s savory and earthy with lots of mushrooms, hearty beans, and a sprinkle of fresh dill.

Ingredients for Mushroom Bean Soup

This mushroom bean soup recipe is brimming with simple ingredients.

• Mushrooms: I used white mushrooms because that’s all my grocery store had. Thinly sliced brown mushrooms would be the best.
• Onion: Finely chopped yellow or white onions add extra umami flavor to healthy soup recipes.
• Garlic: Freshly minced garlic sautéed with the onion enhances aromatics and flavor.
• Oil: You’ll need a splash of oil for frying, I used avocado oil.
• Vegetables: Chop up 3 celery stalks, and grate 2 medium sized carrots.
• Organic cream of mushroom soup: I use Pacific foods brand. If you can’t find organic cream of mushroom soup, look for a brand with no preservatives and artificial flavors. Or see FAQs for a substitute.
• Beans: Use 3 cans of low sodium cannellini beans or white navy beans, rinsed and drained. If you have dried beans on hand, check out how to cook dried beans.
• Vegetable broth: You can use store-bought low sodium broth or homemade vegetable broth.
• Spices: Salt and pepper to taste.
• Herbs: I added bay leaves for an extra layer of flavor, then garnished with fresh dill. Fresh parsley is also a great choice.

How to Make White Bean and Mushrooms Soup

With minimal prep time and some simmering, this mushroom and bean soup is ready in 35 minutes!

There is recipe card below with full instructions for all cooking methods.

• Cook the mushrooms: Preheat a large pot on medium-high heat. Once hot, add oil and mushrooms and cook until golden brown, about 7-8 minutes. Transfer mushrooms to a large bowl.
• Sauté vegetables: Add remaining oil, onion, garlic, carrots, and celery to the same pot and reduce heat to medium. Sauté veggies for 5 minutes, stir in the cream of mushroom soup and cook for 30 seconds.
• Combine: Add mushrooms back in along with beans, broth, salt, pepper, and bay leaves. Stir to combine, cover, and bring to a boil. Then simmer soup on low heat for 20 minutes.
• Garnish and serve: Turn off heat and add dill. I let my white bean soup rest for 5 minutes so the flavors deepen. Then adjust seasonings to taste and serve.

Tips for Best Results

Here are some easy tips for making the best bean soup with mushrooms.

• Use brown mushrooms: For more flavor, use brown mushrooms or portobello mushrooms.
• To clean mushrooms: You can wipe them with damp paper towel. I like to break the rules of cooking and give them a quick rinse with cold water and scrub dirt off with a knife. They brown in a large pot just fine after this wash.
• Use bean broth, if you have it: Bean broth makes a rich, flavorful base for soups and stews. If you have any leftover broth from cooking dried beans, I highly recommend using it!

Variations

• If using dried mushrooms: Dried chanterelles or dried porcini mushrooms should be soaked for 30 minutes in a bowl with cold water. Don’t sauté them first. Instead, add to the pot with the beans and use the soaking liquid to replace some of vegetable broth.
• Other vegetables to add: Make it your own and sauté red or green bell pepper with the other veggies. Or add cubed parsnips, potatoes or sweet potatoes to the pot.
• Extra seasonings at the end: Add a pat of butter after cooking for extra depth of flavor. You can sauté veggies with butter as well. I also like to add freshly grated or minced clove of garlic at the end. Grated garlic will be more flavorful than minced though.

What to Serve with Bean Mushroom Soup?

Mushroom bean soup is a cozy meal on its own. I’ll add some homemade sourdough croutons on top if I have some, or serve crusty bread on the side.

Of course, you can never go wrong with soup and grilled cheese sandwich, or soup and salad combo. This simple butter lettuce salad or lemon kale salad are the perfect pairing.

Mushrooms are a delicious addition to my healthy green bean casserole, so naturally garlic green beans make a delicious side.

How to Make a Freezer Meal

• Before freezing (slow cooker): Preheat large skillet on medium heat and add 1 tablespoon of olive oil. Add onion, carrots, celery and garlic and sauté for 5 minutes, stirring occasionally. Transfer to a resealable gallon size freezer bag. Then cook mushrooms until golden brown. Add to the same bag with other ingredients, except broth, to freeze.
• Instant Pot: In a gallon size Ziploc bag, add all ingredients, except broth. Let as much air out as possible, seal and freeze for up to 3 months. Cook from frozen with 7-8 cups of broth on High pressure for 5 minutes with 20 minutes of Natural Release.
• Slow cooker: Cook from frozen with 7-8 cups of broth for 4 hours on High or 7-8 hours on Low.
• After cooking: Add dill, stir and serve hot.

How to Store and Reheat

Store: Let soup cool, transfer to an airtight container, and refrigerate for up to 5 days.

Freeze: Once cooled, freeze in an airtight container for up to 3 months.

Reheat: To reheat the soup, I like to do place desired amount of soup in a small pot and simmer on the stove on low heat until heated through. Of course, you can always reheat soup in microwave in individual bowls for 2-3 minutes.
