Heat oil in a large skillet or pan over medium heat.
Add the chicken and sear until lightly golden on the outside, about 3–4 minutes.
You’re not trying to fully cook the chicken here. A light golden crust adds deeper flavour to the broth as the chowder cooks.
Transfer the chicken to a 6qt slow cooker. Add the onion, carrots, red peppers (capsicum), corn, creamed corn, potatoes, chicken broth and garlic powder. Stir well to combine.
Cover with lid and cook on high for 3-4 hours or low for 6–8 hours, until the potatoes are fork tender and the chicken is tender enough to break apart easily.
About 45 minutes before the end of cooking time, stir in the cream.
Whisk together the milk and cornstarch until completely smooth, then stir it into the chowder. Cover and continue cooking on high until thickened.
Mixing the cornstarch into cold milk first helps prevent lumps in the chowder.
Use a potato masher to lightly mash some of the potatoes directly in the slow cooker for a thicker texture. Stir in the cheddar and mozzarella until melted and creamy.
Season with salt and pepper to taste. Top with crispy bacon and fresh chives or sliced green onions before serving.

Notes
Storage, Reheating & Freezing
Store leftover chicken corn chowder in an airtight container in the fridge for up to 4 days. The chowder naturally thickens as it cools, so the texture may be much thicker the next day.To reheat, warm it gently on the stove over low heat or in short intervals in the microwave, stirring between each one. Add a splash of milk or chicken broth if needed to loosen the chowder back up.You can freeze the chowder for up to 2 months, but cream-based soups can separate slightly after thawing. Stirring while reheating usually helps bring the texture back together.Happy Cooking! Xx
Please keep in mind that this chowder will thicken a little more while it sits and cools to room temperature. Add a little broth, water or milk when re-heating.
