This hearty rigatoni with sausage, tomatoes, and zucchini has become my go-to dinner for both weeknights and casual entertaining. The tubular pasta perfectly captures the savory sauce while fresh vegetables add brightness to balance the rich Italian sausage.
I first created this recipe when trying to use up summer zucchini from my garden, and it has since become our family's most requested pasta dish. Even my vegetable-skeptical nephew asks for seconds when this hits the table.
Ingredients
- Rigatoni pasta: large tubes that trap the chunky sauce perfectly
- Olive oil: use a good quality extra virgin for best flavor
- Yellow onion: provides the aromatic foundation of the sauce
- Crushed red pepper flakes: adds a gentle warmth without overwhelming heat
- Italian sausage: choose mild sweet or spicy based on your preference
- Garlic: fresh cloves provide essential flavor depth
- Tomato paste: concentrates umami richness throughout the sauce
- Grape tomatoes: burst during cooking creating a fresh sauce base
- White wine: deglazes the pan and adds acidity opt for chicken broth if preferred
- Zucchini: adds freshness texture and nutrition
- Fresh basil: brightens the entire dish with its aromatic finish
- Parmesan cheese: brings salty complexity to each serving
Step-by-Step Instructions
- Boil the Pasta Water:
- Begin by bringing a large pot of generously salted water to a boil. The water should taste like the sea to properly season the pasta from within. This step can be done while preparing the sauce to maximize efficiency.
- Create the Flavor Base:
- Add olive oil to a wide pot over medium heat until shimmering. Add finely chopped onion and crushed red pepper flakes, cooking slowly for a full 10 minutes until the onions become translucent and very soft. This patience builds the foundation of flavor.
- Brown the Sausage:
- Add Italian sausage to the softened onions, breaking it into small bite-sized pieces with a wooden spoon. Cook thoroughly until no pink remains and the edges begin to caramelize, about 5 minutes. The small pieces will distribute meat flavor throughout each bite.
- Build the Aromatics:
- Add minced garlic to the meat mixture and cook for exactly one minute until fragrant but not browned. Immediately stir in tomato paste, coating the meat and onions completely. Allow the tomato paste to cook for 2 minutes to develop deeper flavor.
- Create the Sauce:
- Add the whole grape tomatoes and white wine to the pot, seasoning with salt and pepper. Let this mixture simmer for about 10 minutes, gently pressing on the tomatoes with your spoon to help them burst and release their juices. The sauce will gradually transform from wine and whole tomatoes to a cohesive mixture.
- Cook the Vegetables:
- Stir the diced zucchini into the simmering sauce and cook for 5 minutes until just tender but still holding its shape. The zucchini should retain a slight bite rather than becoming mushy.
- Cook the Pasta:
- While the sauce simmers, add rigatoni to the boiling water and cook until al dente according to package directions, typically 9 to 10 minutes. Reserve half a cup of the starchy pasta water before draining.
- Combine and Finish:
- Immediately transfer the drained pasta to the sauce, tossing thoroughly to coat each piece. Add splashes of reserved pasta water as needed to reach your desired consistency. Finally, stir in the fresh chopped basil just before serving to preserve its bright flavor.
- Serve with Style:
- Divide the finished pasta among warmed serving bowls and top generously with freshly grated Parmesan cheese. Serve immediately while the cheese begins to melt into the hot pasta.

This dish reminds me of summers spent with my Italian grandmother, who taught me that the secret to any great pasta sauce is patience with the onions and garlic. Her wooden spoon, worn smooth from decades of use, became my most treasured kitchen inheritance along with recipes like this one.
Make-Ahead Tips
This pasta dish components can be prepared separately ahead of time for quicker assembly. The sauce can be made up to two days in advance and stored in the refrigerator in an airtight container. Simply reheat gently on the stovetop while your pasta cooks fresh. For best results, add the fresh basil only when reheating and serving. This make-ahead approach actually allows the flavors to meld even more beautifully.

Perfect Substitutions
While rigatoni works beautifully in this recipe, feel free to substitute with penne, ziti, or even farfalle. The key is choosing a pasta shape with nooks and crannies to catch the chunky sauce. For a lighter version, use turkey or chicken sausage instead of pork. Vegetarians can replace the sausage with plant-based alternatives or simply add more vegetables like bell peppers or mushrooms. The wine adds acidity and depth, but chicken or vegetable broth works wonderfully as an alcohol-free alternative.
Serving Suggestions
This robust pasta dish pairs beautifully with a simple arugula salad dressed with lemon juice and olive oil. For a complete Italian dinner experience, start with bruschetta or a light antipasto platter. Garlic bread makes an excellent accompaniment for soaking up extra sauce. For wine pairing, choose a medium-bodied Italian red like Chianti or Montepulciano that complements the tomato and sausage without overwhelming the fresh vegetable flavors.
Cultural Context
This recipe represents the quintessential Italian-American approach to pasta cooking, where fresh seasonal ingredients meet convenience. While traditional Italian cuisine often features simpler combinations, Italian-American cooking embraces the abundance of ingredients available in American markets. The addition of zucchini to pasta with sausage reflects the practical cooking approach of Italian immigrants who incorporated local seasonal vegetables into their traditional recipes, creating new classics that honor both their heritage and their new homeland.
