Cincinnati Chilli over Spaghetti

Known for its fine, spoonable texture and warm spice profile, Cincinnati chilli is a distinctive American way of serving chilli as a sauce for spaghetti rather than as a bowl of beans and meat. Minced beef is simmered with tomato, chilli powder, cumin, cinnamon and cocoa, creating a savoury sauce with gentle heat and subtle sweet-bitter depth. Served over al dente spaghetti with grated cheddar and raw onion, it has the comfort of pasta with the bold seasoning of chilli. The dish suits an easy dinner but still feels recognisable and specific, especially when the sauce is kept loose enough to coat the pasta rather than sit heavily on top.

Why this recipe works

  • Warm, layered spice: Chilli powder, cumin, cinnamon and cocoa give the beef sauce its recognisable savoury depth and gently sweet warmth.
  • Classic sauce texture: Breaking up the beef as it cooks keeps the chilli fine, loose and spoonable, so it coats the spaghetti rather than sitting in large pieces.
  • Good for making ahead: The chilli sauce stores and freezes well, making it easy to reheat gently while cooking fresh spaghetti for serving.

Get the most out of this recipe

Adjust the heat

  • For a milder bowl: Use mild chilli powder instead of hot chilli powder, then adjust with black pepper at the end if needed.
  • For extra warmth: Choose a hotter chilli powder or add a little more towards the end of simmering so the heat stays noticeable.
  • Keep the spice rounded: The cinnamon and cocoa should support the chilli rather than dominate, so taste before adding more warm spices.

Authenticity notes

  • Cincinnati-style serving: Serving the spiced beef sauce over spaghetti with cheddar and onion reflects the familiar Cincinnati chilli style rather than a typical bean-based chilli.
  • Cheese is part of the identity: A generous topping of grated cheddar is a classic finish, adding richness and a sharp contrast to the spiced tomato sauce.

Texture tips

  • Keep the sauce fine: Break the beef up thoroughly as it browns and again during simmering for the traditional finely crumbled texture.
  • Simmer uncovered: Let the sauce reduce until it coats a spoon, stirring occasionally so it thickens evenly without catching.
  • Loosen if needed: If the sauce becomes too thick before serving, add a splash of water and simmer briefly to bring it back together.

Make-ahead tips

  • Make the sauce in advance: The chilli sauce can be cooked ahead, cooled quickly and refrigerated, then reheated gently when ready to serve.
  • Freeze the sauce only: Freeze the cooked chilli sauce rather than the assembled pasta bowl, as fresh spaghetti gives a better texture.
  • Reheat gently: Warm the sauce in a saucepan with a splash of water, stirring until piping hot and spoonable.

  1. Finely chop the yellow onion and set aside about a quarter for serving. Peel and finely chop the garlic.
  2. Heat the olive oil in a saucepan over medium heat, then cook the onion (not the reserved portion) with a pinch of the fine sea salt for 6 to 8 minutes until softened. Stir in the garlic for 30 seconds until fragrant.
  3. Add the minced beef and cook for 6 to 8 minutes, breaking it up with a wooden spoon, until no longer pink. Stir in the hot chili powder, ground cumin, ground cinnamon and cocoa powder for 30 seconds to toast the spices.
  4. Pour in the tomato passata and water, then add the remaining fine sea salt and the black pepper. Bring to a gentle simmer, then cook uncovered for 25 to 30 minutes, stirring occasionally, until thickened to a spoon-coating sauce.
  5. Meanwhile, bring a large pot of well-salted water to the boil and cook the spaghetti until al dente. Drain well in a colander.
  6. Grate the cheddar cheese. Divide the spaghetti between bowls, ladle over the hot chilli sauce, then top with the cheddar and the reserved onion.

Recipe notes

Tips

  • For the classic Cincinnati texture, keep breaking up the beef as it simmers so the sauce stays fine and spoonable.
  • If the sauce thickens too quickly, loosen it with a splash of water and simmer for a few minutes to bring it back together.

Substitutions

  • Replace Cheddar cheese with Monterey Jack cheese for a milder, creamier finish.
  • Replace Hot chili powder with Mild chili powder if you prefer less heat.

Storage

  • Refrigerate up to 3 days
  • Cool the chilli sauce quickly, then refrigerate in a sealed container for up to 3 days. Freeze the sauce for up to 3 months; defrost overnight in the fridge and reheat gently in a saucepan with a splash of water until piping hot. Cook fresh spaghetti for serving, as reheated pasta can turn soft.
