In your trusty crockpot, start by adding the cubed potatoes, chicken broth, chopped onion, minced garlic, and crispy bacon bits. Season the mixture with salt and black pepper. Stir everything gently until well combined.

Cover the crockpot and cook on high for 3-4 hours or low for 5-6 hours until the potatoes are fork-tender.

Once potatoes are tender, mash them to your desired consistency.

Stir in the unsalted butter, flour, milk, and cheddar cheese. Mix until the flour is fully incorporated. Cook on low for another 30 minutes.

Ladle soup into bowls, topping each with green onions and additional toppings as desired.
