Sauté the Vegetables: Heat butter and olive oil in a Dutch oven. Add onion, celery, and carrots. Cook 5 minutes until softened. Stir in garlic for 30 seconds.
Add Broth and Chicken: Pour in chicken broth and bring to a simmer. Add cooked chicken and season with salt and pepper.
Stir in Gnocchi: Add gnocchi and cook 3–4 minutes until soft and floating.
Make It Creamy: Lower heat and stir in the heavy cream. Simmer on low for 5 minutes.
Add Spinach and Finish: Stir in chopped spinach until wilted. Adjust seasoning and serve warm.
Notes
Use rotisserie chicken for ultra-fast prep. Adjust thickness by adding more broth or cream. Gnocchi cooks quickly add it last to prevent overcooking.
