This easy corn chowder is so delicious! The creaminess comes from adding sour cream at the end, so there is no need to mess around with a roux. That makes it lighter, brighter, and much much simpler to make. It's loaded with fresh corn and zucchini and it hits the spot any time of year.
If you are making this in a season when fresh corn on the cob isn't available, use frozen corn. Try to avoid canned corn as it has extra sugar added to it.
