Cut your bacon into pieces and then add them to a pan on medium low heat to crisp up. Once crisp, add the majority of your bacon to your slow cooker while leaving the grease in the pan. Save some bacon to add on top of your soup when you serve it.
8 slices bacon
Remove most of the grease from the pan, but leave about 1-2 tablespoons in the pan so that you can use it to sauteed your diced onion. Cook your onion until slightly brown and then add it to the slow cooker.
1 onion
Add in your chicken breast, bone broth, corn, green chilies, potatoes, and seasoning. Set your slow cooker on low and cook for 5-6 hours.
1 lb chicken breast, 32 oz chicken bone broth, 30 oz canned corn, 4 oz canned green chilies, 2 large potatoes, 4 tsp seasoning
After about 5 hours, remove your chicken from the slow cooker and set it aside. This next part is optional - you can use an immersion blender to blend some of the soup in the slow cooker to create a thicker consistency. Be careful not to blend too much. Just a little.
Shred your chicken and then add it back to your slow cooker.
Make your cornstarch slurry by combining your cold heavy cream with your cornstarch. Whisk until smooth and then add it to the slow cooker. Turn the heat on the slow cooker to high for the remaining 30 minutes and let the soup thicken up.
1 cup heavy cream, 2 tbsp cornstarch
Add your chowder to a bowl and top with additional bacon.
