How to make portobello mushroom soup

This creamy mushroom soup is filled with earthy, rich portobellos, along with some nutty flavoured creminis and my favourite, classic button mushrooms. And there's a TON of them in this soup, so you don't have to worry about them shrinking and there not being enough of them.

Here's how to make this delicious, creamy soup:

1. Saute shallots and garlic in a large pot for 30 seconds. Add mushrooms and cook for 4-5 min until liquid starts to release.
2. Add red wine and flour, whisking to remove lumps.
3. Add white beans, broth, thyme, salt and pepper, bringing to a boil then simmering for 20 min.
4. Stir in milk, then cook for another 5 min. Remove from heat and stir in kale. Serve immediately and enjoy!

Ingredient substitutions and notes

Beans – You can find canned white kidney beans with the rest of the canned legumes at your local grocery store, but if they don't have them you can use regular kidney beans or chickpeas. You can also use 1 cup dried green lentils instead.

Mushrooms – I recommend a mix of portobello, cremini and button mushrooms but you can use any type of mushroom, and also use just one variety or a greater variety. Oyster and shiitake mushrooms would also be a great addition to this soup!

Milk – I used regular 2% milk in this recipe, but you can use other non-dairy varieties such as almond, coconut, cashew or soy milk. Keep in mind that coconut milk will alter the taste of the soup slightly.

Kale – Instead of kale, you can use spinach or chard, or any other type of leafy green of your choosing.

Red wine – Red wine is an optional add-in that makes the broth of this soup richer and more delicious. You can also use white wine, or just omit altogether.

Thyme – Fresh thyme is the best in this recipe, but dried works as well. You can also omit the thyme altogether and add fresh parsley or basil.

Storing and reheating

You can store the leftovers of this soup in the fridge up to 5 days. Reheat in the microwave for 2-3 minutes, stirring halfway through. The leftovers reheat and taste just like new, so this is a great make-ahead recipe.

Freezing portobello mushroom soup

You can also freeze this recipe in individual servings in glass bowls with lids. Reheat in the microwave for 6-7 minutes, stirring halfway through. You can reheat right from frozen, or you can defrost in the fridge overnight and then reheat in the microwave for 1-2 minutes.

What to serve with creamy mushroom soup

This mushroom soup is great on its own, but you can always have some sides along with it! Here are my suggestions:

• Crusty bread and butter
• Naan bread, for dipping
• Side salad
• Roasted broccoli or cauliflower
• Some more protein, such as cooked chicken, steak or shrimp
