Add cauliflower, sweet potato, veggie broth, onion, garlic, green onion, thyme, paprika, red pepper flakes, and salt to the slow cooker.
If the broth you're using is on the saltier side, feel free to skip the salt and simply add it in later, to taste. Same goes for the red pepper flakes - if you want a super mild soup you can always sneak some in later. I added a teaspoon of RPF to mine and it gave the soup a delightful little zing.
Cover and cook for 4-5 hours on high.
Once the veggies are fabulously tender, turn off the crock-pot and add your milk and cream cheese. Blend using an (my favorite appliance ever!) and you're good to go!
No immersion blender? No problem! You can use a blender to puree the soup, working in batches and careful not to overfill the blender as hot soup expands when blended. Fill maybe halfway to 3/4 full each round.
Ladle soup into bowls and enjoy right away with a mountain of your favorite toppings, then store the remaining soup in your fridge or freezer. As written, the recipe will yield around 4 quarts of soup which equates to 16 eight-ounce cups or 8 hearty bowls. It tastes great the first day and even better the next!
This soup will keep for 4-5 days in the refrigerator and freeze marvelously for 2-3 months! Simply store the soup sans-toppings and add all your goodies upon reheating. Easy peasy!
