American Chop Suey (One-Pot Macaroni with Minced Beef and Cheddar)

American chop suey is a homely American one-pot pasta dish, closer to a tomatoey beef macaroni than the Chinese-American name might suggest. Minced beef, onion, green pepper and garlic give the sauce its savoury base, while tomato purée, chopped tomatoes and Worcestershire sauce add depth without making it heavy. Cooking the elbow macaroni directly in the sauce helps it absorb flavour and leaves a glossy, thick finish. Cheddar stirred through at the end makes it rich and comforting, ideal for an easy dinner that reheats well and can be adjusted with different peppers or cheeses.

Why this recipe works

  • One-pot efficiency: The macaroni cooks in the tomato and beef sauce, reducing washing-up while helping the sauce thicken naturally with pasta starch.
  • Built-in savoury depth: Browning the beef, softening the vegetables and briefly cooking the tomato purée create a fuller base before the pasta is added.
  • Comforting finish: Cheddar melts through the hot pasta at the end, giving the dish a rich, rounded finish without needing a separate cheese sauce.

Authenticity notes

  • New England-style comfort food: American chop suey is especially associated with New England home cooking, where it is commonly served as a simple macaroni, beef and tomato one-pot meal.
  • Homestyle rather than formal: The dish is defined by practicality: browned minced beef, peppers, tomatoes and macaroni cooked together until hearty and scoopable.
  • Cheese varies: Some versions are served without cheese, while others finish with cheddar for a richer, more casserole-like result.

Ingredient notes

  • Use elbow macaroni: Elbow macaroni suits this style because the small shape cooks evenly in the sauce and holds the beef and tomato mixture well.
  • Brown the beef properly: Letting the minced beef brown and allowing excess liquid to evaporate gives the sauce a deeper savoury base.
  • Grate the cheddar first: Having the cheese ready before the pasta finishes means it can be stirred in while the pot is still hot enough to melt it smoothly.

Common mistakes

  • Letting the sauce get too tight: If the macaroni is not tender but the sauce has thickened too much, add a splash of water and continue simmering gently.
  • Not stirring the pasta: Because the macaroni cooks directly in the sauce, stir regularly to stop it catching on the base of the pot.
  • Taking the pasta too far: Stop simmering once the macaroni is tender and the sauce looks glossy; it will continue to soften slightly from the residual heat.

Make-ahead tips

  • Good for portions: Cool quickly, then refrigerate in sealed containers for easy reheating during the week.
  • Reheat gently: Warm with a splash of water over low heat, stirring often, until piping hot so the sauce loosens without drying out.
  • Freezer-friendly: Freeze in portions after cooking, then defrost overnight in the fridge before reheating thoroughly.

  1. Finely chop the onion and green pepper, and crush the garlic. Grate the cheddar and set it aside.
  2. Put a large pot over medium-high heat and add the minced beef. Cook for 6 to 8 minutes, breaking it up with a wooden spoon, until browned and any liquid has mostly evaporated.
  3. Stir in the onion and green pepper with the fine sea salt and black pepper. Cook for 6 to 8 minutes, stirring often, until the vegetables have softened.
  4. Add the garlic and tomato purée and cook for 1 minute, stirring, until fragrant and slightly darkened. Stir in the Worcestershire sauce.
  5. Pour in the canned chopped tomatoes and add 600 ml water, then bring to a steady simmer. Stir in the elbow macaroni and reduce to medium-low so it bubbles gently.
  6. Simmer for 10 to 12 minutes, stirring every minute or two to stop the pasta catching, until the macaroni is tender and the sauce looks glossy and thick. If it tightens too quickly before the pasta is done, add a splash of water and keep simmering.
  7. Take the pot off the heat and stir through most of the cheddar until melted. Sprinkle the remaining cheddar over the top, cover for 2 minutes to melt, then serve hot.

Recipe notes

Tips

  • Stir the macaroni frequently as it simmers; this releases starch and helps the sauce turn glossy while preventing sticking.
  • For a deeper savoury note, let the tomato purée cook until it turns a shade darker before adding the tomatoes.
  • If serving vulnerable groups, make sure the minced beef is cooked through with no pink remaining and the sauce is piping hot.

Substitutions

  • Replace Cheddar cheese with Parmesan for a sharper, saltier finish.
  • Replace Green pepper with Red pepper for a sweeter flavour.
  • Replace Worcestershire sauce with Soy sauce for a similar savoury depth.

Storage

  • Refrigerate up to 3 days
  • Cool quickly, then refrigerate in a sealed container. Reheat with a splash of water in a saucepan over low heat, stirring often, until piping hot; or microwave in short bursts, stirring between each. Freeze in portions for up to 2 months and defrost overnight in the fridge before reheating.
