There are many online recipes that are already SCD legal or can be modified to be legal. The following is one example
Make Chicken stock
Bring stock to a low simmer. About 1/2 full in your soup pot.
While stock warms up, saute 1 chopped onion, 3-4 celery stalks, and several peeled carrots in olive oil until fragrant. Rough chop as everything gets pureed.
Add sauteed veggies to stock.
Either pre roast or peel and chop 1-2 butternut squashes depending on how much stock you use. Add to stock.
(I fill my soup pan a little shy of 1/2 way with stock. The veggies will fill the pot and just be covered by the stock. More veggie, thicker soup, less veggies, thinner soup. My son likes it thick.)
Season with salt, pepper, thyme
Slow boil for about 1 hour, until carrots are very tender. Turn off heat and let sit for awhile.
Puree soup in batches.
I have added cooked chicken to make it more protein rich t some batches.
Top with yogurt if you can do dairy and some ceyanne pepper flakes
If you like nutmeg or cinnamon you can sprinkle that on too.
