Ingredient Breakdown

Ingredients for warm slow cooker sweet potato and spinach soup for cozy winter nights

The key ingredients in this recipe are sweet potatoes, spinach, garlic, onions, and chicken broth. Sweet potatoes provide a natural sweetness and creamy texture, while spinach adds a burst of nutrients and flavor. Garlic and onions add a depth of flavor and aroma, while chicken broth helps to thin out the soup and add moisture. When selecting sweet potatoes, look for ones that are firm and have a smooth, even skin. For spinach, choose fresh leaves with no signs of wilting or damage. You can also use frozen spinach as a substitute, just be sure to thaw and squeeze out excess moisture before adding it to the soup.

How to Make warm slow cooker sweet potato and spinach soup for cozy winter nights

Chop the Onions and Garlic

Chop 1 large onion and 3 cloves of garlic. Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onions and cook until they're translucent and starting to caramelize, about 8-10 minutes.

Add the Garlic and Cook

Add the minced garlic to the skillet and cook for an additional 1-2 minutes, stirring constantly to prevent burning.

Add the Sweet Potatoes and Chicken Broth

Add 2 large sweet potatoes, peeled and cubed, to the slow cooker. Pour in 4 cups of chicken broth and add the cooked onion and garlic mixture.

Cook on Low

Cook the soup on low for 6-8 hours or on high for 3-4 hours. The sweet potatoes should be tender and easily pierced with a fork.

Add the Spinach and Season

Stir in 1 cup of fresh spinach leaves and cook until wilted. Season the soup with salt, pepper, and any other desired spices or herbs.

Serve and Enjoy

Ladle the soup into bowls and serve hot, garnished with a sprinkle of paprika or a dollop of sour cream, if desired.

Tips for Perfect Results

Use High-Quality Broth:

Using a high-quality chicken broth will make a big difference in the flavor of the soup. Look for a low-sodium option or make your own broth from scratch.

Don't Overcook the Sweet Potatoes:

Sweet potatoes can become mushy and unappetizing if overcooked. Check the soup regularly and remove the sweet potatoes when they're tender but still hold their shape.

Add Spinach at the End:

Adding spinach to the soup at the end of cooking helps preserve its nutrients and flavor. Simply stir it in and let it wilt into the soup.

Experiment with Spices:

This recipe is a great base for experimentation. Try adding different spices, such as cumin, paprika, or nutmeg, to give the soup a unique flavor.

Use Fresh Herbs:

Fresh herbs, such as parsley or cilantro, can add a bright and refreshing flavor to the soup. Simply chop them up and stir them in at the end of cooking.

Make it Creamy:

For a creamier soup, try adding a splash of heavy cream or coconut milk. This will add richness and depth to the soup without overpowering the other flavors.

Serve with Crusty Bread:

Serving the soup with a side of crusty bread is the perfect way to soak up all the flavorful broth. Try using a rustic bread or a baguette for the best results.

Freeze for Later:

This soup freezes beautifully, making it a great option for meal prep or future meals. Simply portion it out into airtight containers and freeze for up to 3 months.
