To make your soup heartier, you can add more vegetables like carrots, red bell pepper, or celery! For a spicy kick, add diced jalapeño, red pepper flakes, or cayenne pepper.

Step 9:Once thickened to your liking, serve the soup and top it with chopped parsley, if desired.

👩🏽‍🍳 Tips for the best instant pot corn chowder

⭐ Dice the potatoes into small, even chunks to ensure they cook uniformly and absorb the flavors of the broth and corn.

Make sure your cornstarch mixture is smooth and lump-free before adding it to the pot to avoid clumps in your chowder. When adding half and half and cheese, keep the Instant Pot on low to avoid curdling. Gentle heat will blend the dairy smoothly into the chowder. This recipe calls for a quick release to stop the cooking process immediately and prevent overcooking the potatoes.
