Kale and Sausage Soup

Melt butter in a stockpot over medium-low heat. Whisk in flour and stir until the mixture becomes paste-like and light golden brown, about 3 minutes. Gradually whisk chicken broth and water into the roux, and bring to a simmer over medium heat. Add onion, garlic, thyme, bay leaves, and sage; cook until the mixture has thickened onions are tender, 10 to 15 minutes.

Meanwhile, heat a large nonstick skillet over medium-high heat. Cook and stir sausage in the hot skillet until browned and crumbly, 5 to 7 minutes. Transfer sausage to a paper towel-lined plate to remove excess grease.

Add sausage, potatoes, kale, and mushrooms to the stockpot. Simmer until potatoes are tender, about 45 minutes. Add half-and-half and season with salt and pepper.
