Low Carb Ingredients!

MUSHROOMS: Mushrooms are a mild-flavored vegetable that give this homemade mushroom soup a delicious taste and wonderful texture. Feel free to mix and match different varieties, like thin-sliced portobellos, button mushrooms, cremini mushrooms, or baby Bellas.

CAULIFLOWER: Cauliflower is a carb-lovers dream! Because of its mild flavor, it is truly a multi-purpose veggie.

FLAVOR: Cream cheese and chicken stock give the soup a velvety texture and a little bit of garlic and fresh thyme give it a savory flavor.

Tips For the Best Soup!

Let the cream cheese come to room temperature before stirring into the soup so it blends quickly and easily.

Cut cauliflower pieces into small, uniform sizes so that they cook quicker and are easier to blend.

For a thicker soup, stir in a little heavy whipping cream. Or if a thin consistency is desired, stir in a little milk.

What To Do with Leftovers

Keep leftover homemade mushroom soup in a covered container in the fridge for up to 3 days. Reheat leftovers on the stove before serving. Alternately, freeze leftover mushroom soup in an ice cube tray and store cubes in a zippered bag. Pop one or two out to add flavor to sauces, stir-fries or blend into cauliflower mashed potatoes.
