Ingredients

Base:
  • 6 slices cooked bacon*, diced
  • 3–4 cups chicken or vegetable stock
  • 2 lbs Yukon gold potatoes**, peeled (if desired) and diced
  • 1 medium white or yellow onion, diced
Roux:
  • 4 Tbsp bacon grease* (or butter)
  • 1/3 cup all-purpose flour
  • 1 (12 oz) can 2% evaporated milk
To Finish:
  • 1 cup shredded reduced-fat sharp cheddar cheese
  • 1/2 cup plain low-fat Greek yogurt or low-fat sour cream
  • 1 tsp kosher salt (or to taste)
  • 1/2 tsp freshly cracked black pepper  
Optional Toppings:
  • Sliced green onions or chives
  • Extra shredded cheese
  • Extra turkey bacon
  • Sour cream  

Instructions

  1. Load the Slow Cooker:
    Add the cooked bacon, 3 cups of stock, diced potatoes, and onion to your slow cooker. Stir to combine.  
    • Cook on low: 6–8 hours
    • Cook on high: 3–4 hours
      until the potatoes are tender.  
  2. Make the Roux:
    In a small saucepan, melt the butter (or bacon grease) over medium-high heat.
    Whisk in the flour and cook for 1 minute, stirring occasionally.
    Gradually whisk in the evaporated milk until smooth.
    Bring to a simmer and cook until thickened.  
  3. Combine:
    Pour the thickened milk mixture into the slow cooker. Stir well.
    Add the cheddar cheese, Greek yogurt (or sour cream), salt, and pepper. Stir until combined.
  4. Adjust Texture:
    • For a thicker soup, mash about half the potatoes directly in the slow cooker.
    • For a thinner soup, add 1–2 cups of warmed stock.  
  5. Serve:
    Taste and adjust seasoning if needed. Serve warm with your favorite toppings.
    Leftovers can be refrigerated in a sealed container for up to 3 days. (Not recommended for freezing.)  

Notes

  • Turkey Bacon: Cook it however you like — pan-fried, baked, or even pre-cooked. If frying, dice it first so it crisps up evenly. You can use a little butter or olive oil in place of bacon grease when making your roux for that same rich flavor.
  • Potatoes: Yukon golds are ideal for their buttery flavor and creamy texture. Russet or red potatoes also work.
  • Vegetarian Option: Use vegetable stock, skip the bacon, and add 2–3 tsp Old Bay seasoning for flavor.
