This Italian sausage soup is a cozy one-pot meal that's laden with sweet sausage, tender gnocchi, spinach, and topped with crispy pancetta. It's perfect winter comfort food.
Heat a drizzle of olive oil in a large pot over medium heat.
Cook the sausage, breaking apart the clumps, until browned, 6 to 8 minutes. Transfer the sausage crumbles with a slotted spoon to a paper towel-lined plate.
Add the pancetta and cook until chewy-crispy, about 5 minutes. Transfer the dice to a second paper towel-lined plate.
Dump in the onion and cook, stirring often, until it begins to soften, 5 to 7 minutes. Stir in the garlic and pepper flakes and cook for 1 minute more.
Crank the heat to medium-high and splash in the wine. Scrape up the brown bits from the bottom of the pot with a wooden spoon and let the wine bubble until nearly evaporated, about 1 minute.
Pour in the broth and add the sausage. Let the soup come to a simmer, then stir in the gnocchi and spinach. Cook until the spinach is wilted and the gnocchi are tender, about 3 to 5 minutes.
Taste the soup and adjust the seasoning with salt and pepper, if needed.
Remove from the heat and divvy the soup among bowls. Top with pancetta and a sprinkling of Parmigiano-Reggiano. Serve immediately.
Notes
Use caution when adding salt--There are lots of salty elements in this soup, so be sure to taste a couple of spoonfuls before seasoning with additional salt at the end.
Storage--Store leftover soup in a sealed container in the refrigerator for up to 4 days.
Reheating--Reheat leftover soup in a saucepan over medium heat until warmed through. If the soup is too thick, pour in a little broth or water to thin it.
