In a large pot, heat 2 tsp oil on medium-high. Add mushrooms and sauté, stirring occasionally, until liquid evaporates, about 5 minutes. Reduce heat to medium and stir in remaining 1 tsp oil, carrots, celery, onion, garlic and spinach. Sauté until onion is soft and translucent but not browned, about 10 minutes.
Add turkey and cook, breaking up with a wooden spoon, until cooked through, about 10 minutes. Add tomato paste and cook, stirring frequently, for 3 minutes; if needed, gradually stir in up to ½ cup water to prevent over-browning.
Increase heat to medium-high and stir in chicken broth. Bring to a simmer and cook, stirring and scraping up browned bits with a wooden spoon, for 2 minutes. Reduce heat to medium-low and stir in milk, fennel, cardamom and orange. Cover and simmer very gently for 45 minutes. Remove orange.
About 15 minutes before turkey mixture is done, cook pasta al dente according to package directions. Drain and rinse with cold water. Drain well and add to turkey mixture. Stir to coat and simmer gently for 5 minutes. To serve, top with ricotta, basil and pepper.
Cincinnati chili is a bit thinner and sweeter than southwestern-style chili, and is traditionally served over spaghetti. Here, we've cut back the fat without compromising its trademark meaty flavor by using tender lean ground turkey.
No holiday menu is complete without the main event: A perfectly seasoned, succulent turkey. Rosemary, garlic and onion lend classic flavors to this spice rub and a porcini pan sauce provides a gorgeous, rich flavor for dipping.
