Start by melting the butter in a large pot over medium heat. Add your diced onions and cook until they become translucent and soft. Stir in the minced garlic and cook for just another minute until the kitchen smells incredible.

Sprinkle the flour over the butter and onions. Whisk constantly for about two minutes to cook out the raw flour taste. This ensures your soup has a smooth professional finish.

Gradually pour in the chicken broth while whisking vigorously to avoid any lumps. Once combined stir in the milk or heavy cream. Bring the mixture to a gentle simmer.

Stir in the green chiles tomatoes cumin and chili powder. Let the flavors meld together for about ten minutes on low heat.

Turn the heat to low. This is crucial because high heat can cause cheese to break or become grainy. Add the shredded cheese one handful at a time stirring constantly until completely melted and silky.

Taste your creation. Add salt and pepper as needed. If you want a heartier version consider a homemade winter minestrone soup recipe family style twist by adding extra vegetables.
