Ingredients and substitutions

- Roux - Butter and all-purpose flour create a roux, which is a paste that thickens your soup.
- Milk - I recommend whole milk for a creamy, thicker soup. Lower fat milks will work, but keep in mind your soup will turn out on the thin side.
- Broth - I used vegetable broth, but chicken broth is a good substitute. If you're using low-sodium broth, add more seasoning to taste to account for the lost flavor.
- Produce - Potato, zucchini, and corn serve as the bulk of the soup. Zucchini could be substituted with yellow squash if desired. Yukon gold potatoes are my go-to potato, but sweet potatoes would work great as a substitute. Corn can be frozen, cut fresh off the cob, or canned.
- Flavor - Onion, garlic, salt, pepper, thyme, and red pepper flakes add flavor to your soup.
