Pro Tips

• For a thicker chowder, make a slurry by whisking 1 tablespoon of xanthan gum with 2 tablespoons of cold water. Stir it into the finished chowder on the ‘Saute’ setting until thickened.
• Don’t overcook the clams. The 5-minute cook time is perfect for keeping them tender. A longer time or natural release can result in a rubbery texture.
• Garnish with fresh chives or parsley and some of the reserved crispy bacon for extra flavor and a beautiful presentation.
• For a low-carb potato substitute, add 1 cup of diced daikon radish or turnips along with the onion and celery.
