2 pounds red potatoes, cut into 2 inch pieces (you can peel them but I never do – I love red potato skins in my mashed potatoes!)
½ cup sour cream (or plain greek yogurt)
¼ cup milk
2 teaspoons minced garlic
2 teaspoons salt
1 teaspoon black pepper
Spray the inside of a slow cooker with cooking spray. Add chopped potatoes. Cover and cook 2-3 hours on high or 5-6 hours on low.
Add sour cream, milk, garlic, salt, and pepper to potatoes. Use a hand mixer to blend together all ingredients.
