White Bean Mushroom Spinach Soup

It only took a week, but I went through my entire stash of soup in the freezer.

Exhausted from busy days in the pre-holiday rush of deadlines, I couldn’t bring myself to pack lunch for the next day the night before.

I like to do as much as I can before bedtime, or the morning will be complete chaos.

Freezing soup is an absolute lifesaver for work lunches.

Packing lunch is a great way to save money and most importantly, to be healthy.

When you make your own food, you know exactly what’s going in it whether your priorities are organic, low sodium or something else.

My typical soups are made with pureed veggie bases like sweet potatoes.

I also love cracking open a can of tomatoes to make soups like one with red lentils and butternut squash.

To change up my routine, I have been reaching for more broth-based soups

Of course they are still filled with vegetables.

How To Make White Bean Mushroom Spinach Soup

I really love this white bean mushroom spinach soup. Part of the reason is because it’s fast and easy to cook. 

To start, I sauté white onions over medium heat to gently let them soften.

Then I add sliced cremini mushrooms followed by garlic and lots of minced fresh rosemary.

Once the mushrooms are cooked, it’s time to stir in the beans and vegetable broth. 

I like great northern beans, but you can also use cannellini beans.

With everything in the pot, I bring the soup to a boil and then reduce the heat to let the fragrant mixture simmer. 

In just 15 minutes, the beans thicken this vegan soup giving it a kind of creamy constancy.  

When I add baby spinach, it always seems like way too much, but then the leaves wilt and make themselves right at home with the rest of the ingredients in the pot.

I have already started including white bean mushroom spinach soup in my rotating repertoire of winter soups.
