Prep Vegetables: Dice the potatoes, onion, carrots, and celery so they cook evenly and blend smoothly into the chowder.
About 3 cups diced red potatoes
Load the Slow Cooker: Add the diced vegetables, garlic, ham, thyme, corn with its liquid, and chicken broth to the slow cooker, ensuring everything is submerged.
1 small onion, 2 carrots, 2 stalks celery, 2 cloves garlic, 1 teaspoon dried thyme, 8 ounces diced ham, 1 can corn, 4 cups chicken broth
Slow Cook: Cover and cook on low for 8–10 hours until the vegetables are tender and the flavors have fully developed.
Add Milk: Pour in the milk and stir gently so the potatoes stay intact.
2 cups milk
Thicken Chowder: Stir in 1 cup of instant mashed potato flakes, cover, and let it sit for 5 minutes. Add up to 1 more cup if you prefer a thicker chowder.

Finish Cooking: Cook for an additional 20 minutes on low, then taste and season with salt and pepper.
