Heat olive oil in a large pot over high heat. Once hot, add the sausage and sear for about a minute per side. Crumble and cook until deeply browned. (More color on the meat=more flavor). Remove with a slotted spoon to a paper towel-lined plate, leaving 2–3 tablespoons of grease in the pot. Drain off excess if there is more than that.
Add onion, celery, and carrot to the pot. Cook, stirring occasionally, for 7–9 minutes, or until tender. Take your time here; the veggies won’t soften much more later. Add garlic and cook for 30 seconds, stirring constantly.
Stir in salt, pepper, Italian seasoning, parsley, oregano, and thyme. Mix for about 15 seconds, then add butter and stir until melted.
Sprinkle flour over vegetables and whisk constantly for 1 minute. Slowly pour in the broth, whisking until smooth and slightly thickened. Gradually whisk in the milk and cream, then bring to a gentle boil.
Once boiling, reduce the heat to medium. Add the gnocchi (see note 1), kale, and cooked sausage. Simmer for 2–4 minutes, or until the gnocchi is tender. Taste and adjust seasoning as needed.
Ladle into bowls and top with fresh thyme if desired. Serve with hearty buttered bread on the side.

Notes
Note 1: I like Rana’s refrigerated gnocchi best here. Use a brand you enjoy, as some shelf-stable versions can taste a bit stale. Rana’s cooks in 2–3 minutes, so I add it right at the end. If your gnocchi takes longer, add it earlier and cook it 1 minute less than the package directs before adding the sausage and kale.Soup Storage: Store in an airtight container in the fridge for up to 3 days. Add a splash of milk or broth when reheating since the gnocchi will soak up some liquid. Or, to keep the gnocchi from getting too soft, scoop it out with a wire skimmer and store it separately. Freezing isn’t recommended, as the dairy and gnocchi don’t thaw well.
