Cook the Bacon: In a large pot, cook 6 slices of bacon over medium heat for about 6-8 minutes, or until crispy and golden brown. Transfer the bacon to a paper towel-lined plate to drain excess fat, leaving about 2 tablespoons of drippings in the pot for flavor.

Sauté Aromatics: In the same pot with the bacon drippings, add one chopped onion and sauté on medium heat for 3-4 minutes until soft and translucent. Next, add 3 minced garlic cloves and cook for an additional 1-2 minutes until fragrant.

Simmer the Broth: Pour in 4 cups of chicken or vegetable broth, bringing the mixture to a gentle simmer over medium-high heat. Allow the broth to simmer for about 5 minutes.

Cook the Gnocchi: Once simmering, add 1 pound of gnocchi to the pot. Cook according to package instructions, usually around 2-3 minutes, until the gnocchi floats to the surface.

Add the Cheese: Reduce the heat to low and begin adding 2 cups of grated sharp cheddar cheese gradually while stirring continuously until melted.

Combine the Bacon and Season: Return the crispy bacon to the pot and stir to combine well. Season with salt and pepper to taste.

Add Greens and Serve: Stir in 2 cups of fresh spinach, kale, or arugula just before serving. Ladle the warm soup into bowls and serve immediately.
