Rigatoni with Sausage, Tomatoes, and Zucchini builds a lively pan sauce from browned Italian sausage, burst grape tomatoes, tomato paste, wine or broth, and tender diced zucchini. Fresh basil and Parmesan finish the pasta without turning it into a heavy baked dish.
The recipe serves 6 and takes 15 minutes to prepare plus 25 minutes to cook, for a 40-minute total. Keep the pasta water moving while the sauce develops so both are ready together.

How to Make Rigatoni with Sausage, Tomatoes, and Zucchini
- Start pasta water: Bring a large pot of salted water to a boil over medium-high heat for the pasta.
- Cook onion and sausage: Heat olive oil in a large, wide pot over medium heat. Add onion and red pepper flakes, cooking until onion is very soft, about 10 minutes. Add sausage and break it into small pieces with a wooden spoon. Cook until browned with no pink remaining.
- Add aromatics: Add garlic and cook for 1 minute until fragrant. Stir in the tomato paste and cook briefly.
- Build the sauce: Add tomatoes, wine or broth, salt, and pepper. Cook for about 10 minutes, stirring occasionally, until tomatoes burst and release their juices. Gently press tomatoes with a wooden spoon if needed. Stir in diced zucchini and cook for 5 minutes.
- Cook pasta: Add rigatoni to the boiling water and cook for 9-10 minutes until al dente. Reserve 1/2 cup of pasta water before draining.
- Combine and serve: Toss the drained pasta immediately into the pot with the sauce. Add reserved pasta water if needed for consistency. Stir in fresh basil, then divide among bowls and top with grated Parmesan cheese.
Start pasta water
Start a large pot of salted water over medium-high heat before working on the sauce. A generous pot gives 3/4 pound rigatoni room to circulate. Bringing it to a full boil early prevents the sauce from sitting too long while the pasta water catches up.
Cook onion and sausage
Heat 3 tablespoons olive oil in a wide pot over medium heat. Cook the finely chopped large yellow onion, with the optional 1/4 teaspoon red pepper flakes, for about 10 minutes until very soft. Then brown the 1 pound sausage completely, breaking it into small pieces with a wooden spoon.
Add aromatics
Add all 5 minced garlic cloves only after the sausage has browned. One minute is enough to release their aroma without scorching them. Stir in the 3 tablespoons tomato paste and let it contact the hot pan briefly so its concentrated flavor spreads through the sausage.
Build the sauce
Add 2 cups grape tomatoes, 1 cup white wine or chicken broth, 1 teaspoon salt, and 1/2 teaspoon black pepper. Cook about 10 minutes, pressing reluctant tomatoes gently. Add exactly 2 diced small zucchini only after the tomatoes burst, then cook them for 5 minutes.
Cook pasta
Boil the 3/4 pound rigatoni for 9–10 minutes until al dente. Before draining, reserve exactly 1/2 cup pasta water. Do not rinse the pasta; its surface starch is useful when the tubes are tossed immediately into the sauce.
Combine and serve
Move the drained rigatoni straight into the sauce pot and toss thoroughly. Add reserved pasta water only as needed for consistency. Stir in 1/2 cup chopped fresh basil last, divide the pasta among six bowls, and finish with freshly grated Parmesan.
Choose the Sausage You Prefer
The recipe works with mild, sweet, or spicy Italian sausage. Whichever style you choose, cook it until browned with no pink remaining. Keep the pieces small enough to travel inside and around the rigatoni instead of leaving large chunks that dominate individual servings.
Let the Tomatoes Make the Sauce
The grape tomatoes need roughly 10 minutes with the wine or broth to burst and release their juices. Stir occasionally and press only those that remain whole. Their liquid combines with tomato paste and sausage drippings to form the sauce; no separate jarred sauce is required.
Add Zucchini at the Right Time
Zucchini needs only 5 minutes after the tomato stage. Adding it earlier can make the pieces collapse before the rigatoni is ready. Dice both small zucchini to a similar size so they soften evenly while retaining enough shape to be visible in the finished pasta.
Use the Reserved Pasta Water Carefully
The reserved 1/2 cup is insurance, not a mandatory final addition. Toss first, then add a splash only if the sauce needs loosening. Starchy water helps the sauce cling to the ridges and hollow centers without diluting it as plain water would.
Coordinate the Forty-Minute Meal
Chop the onion, garlic, zucchini, and basil during the 15-minute preparation window. Once cooking begins, the onion's 10 minutes and the tomato sauce's 10 minutes can overlap with heating the pasta water and boiling the rigatoni for 9–10 minutes.
Conclusion
Soften the onion for about 10 minutes, brown 1 pound Italian sausage, then add 5 garlic cloves and tomato paste. Simmer grape tomatoes with wine or broth, salt, and pepper for about 10 minutes; add two zucchini for 5 minutes. Boil rigatoni 9–10 minutes, reserve 1/2 cup pasta water, toss with the sauce, and finish with basil and Parmesan.
