This spaghetti with beef and zucchini is a fast, satisfying pasta dinner built around a savory tomato sauce, tender vegetables and plenty of Parmesan.

Instructions

  1. Wash and dry the zucchini and thyme. Bring a large pot of salted water to a boil.
  2. Quarter the zucchini lengthwise, then slice it into 1/2-inch pieces. Halve, peel and dice the onions. Mince the garlic. Strip the thyme leaves from the stems, discard the stems and roughly chop the leaves.
  3. Heat the olive oil in a large pan over medium-high heat. Add the ground beef and break it up with a spoon. Cook, tossing and stirring, until browned but not fully cooked through, 4 to 5 minutes. Season with salt and pepper.
  4. Add the diced onions and zucchini to the pan with the beef. Cook, stirring occasionally, until the vegetables soften, about 5 minutes.
  5. Stir in the garlic, thyme, Italian seasoning and soy sauce. Cook until fragrant, about 30 seconds.
  6. When the water is boiling, add the spaghetti. Cook, stirring occasionally, until al dente, 9 to 11 minutes. Carefully reserve 1 cup of the pasta cooking water, then drain the spaghetti.
  7. Add the crushed tomatoes and reserved pasta water to the pan with the beef and vegetables. Bring to a boil, then reduce the heat and simmer until the sauce thickens, about 5 minutes. Taste and season with salt and pepper.
  8. Add the drained spaghetti to the pan and toss until evenly coated in the sauce. Divide among plates and finish with Parmesan cheese and chili flakes to taste.

Recipe Tips

Reserve the pasta water before draining; the starch helps loosen the sauce and coat the spaghetti.

For a thicker, deeper-tasting sauce, simmer the tomato mixture a little longer if you have extra time.

Add chili flakes at the end so each serving can be adjusted for heat.

Break up the beef as it browns so the sauce has an even, hearty texture.

Why add soy sauce to a tomato pasta sauce?
