1-First Step: Prep the potatoes and bacon Start by piercing the 4 scrubbed potatoes several times with a fork. This helps steam escape while they cook. Microwave the potatoes for 12 to 15 minutes, or until they feel tender when pressed. If you prefer, you can bake them at 350°F for about 45 minutes instead. While the potatoes cook, place 8 bacon slices in a skillet and cook them until crisp. Transfer the bacon to a paper towel lined plate, then crumble it once it cools. After the potatoes are done, let them cool just enough to handle. Halve them, remove the skins, and cut the potato flesh into chunks. You can leave some skin on if you like a more rustic texture. That little bit of skin adds a nice bite and helps the soup feel extra homemade.

2-Second Step: Build the flavor base Set a large pot over medium heat and melt the 4 tablespoons of unsalted butter. Add a little of the reserved bacon fat for extra flavor if you want a richer soup. Stir in the minced garlic and yellow onion, then cook for 2 to 3 minutes until softened and fragrant. This step gives the soup a savory base that tastes like it simmered all afternoon, even though it comes together fast. Next, whisk in the 1/3 cup flour. Cook it for 1 to 2 minutes, stirring often so it does not taste raw. This simple step helps the soup thicken later. Keep the heat at medium and keep whisking so the mixture stays smooth.

3-Third Step: Add the liquids slowly Slowly whisk in the 2 cups low-fat milk, 1 cup half and half, and 2 cups chicken stock. Add them a little at a time so the soup base stays lump free. Once everything is mixed in, bring the pot to a light simmer. You do not want a hard boil here. Gentle heat gives the soup a creamy texture and keeps the dairy from breaking. At this stage, the soup should look smooth and slightly thick, but it will continue to build body as it simmers. Stir often and keep an eye on the bottom of the pot so nothing sticks.

4-Fourth Step: Season and thicken Add 1 teaspoon kosher salt, 1/2 teaspoon garlic salt, and 1/2 teaspoon black pepper. Then taste and add more salt if needed. Let the soup simmer until it thickens a bit more. This usually takes only a few minutes, but the exact time can vary depending on how hot your stove runs and how much evaporation happens. The soup should coat the back of a spoon lightly. If it seems too thick, add a splash more stock or milk. If it seems too thin, let it simmer a little longer. This is a great time to use your judgment and make it work for your family.

5-Fifth Step: Stir in the cheese, bacon, and sour cream Reduce the heat to low before adding the 1 cup mild cheddar cheese, 1 cup sharp cheddar cheese, crumbled bacon, and 1 cup sour cream. Stir until the cheeses melt and the soup turns rich and creamy. Add the potato chunks last so they stay in nice pieces instead of breaking apart too much. Fold them in gently until they are warmed through. If you want a smoother soup, mash a few potato chunks right in the pot with your spoon. If you like a chunkier bowl, leave the pieces whole. Either way, the flavor stays classic and comforting.

6-Final Step: Serve hot with chives Ladle the soup into bowls and top each serving with fresh chives. You can also add a little extra cheese, more bacon, or a spoonful of sour cream if you want that classic loaded baked potato look. Serve right away while the soup is hot and creamy.
