A hearty, deeply savory Italian sausage tomato sauce made by browning sausage and simmering with crushed tomatoes — rich, chunky, and ready in 35 minutes.
Heat olive oil over medium-high heat. Add sausage meat and cook 6–8 minutes breaking into crumbles until deeply browned. Remove and set aside leaving fat in pan.
Reduce to medium. Add onion to same pan, cook 5–6 minutes until soft. Add garlic, oregano, red pepper flakes, cook 60 seconds.
Deglaze with red wine, scraping up fond, cook 2 minutes. Add crushed tomatoes and return sausage. Season with salt and pepper.
Simmer uncovered medium-low 18–20 minutes until thick. Add pasta water, toss rigatoni in pan. Remove from heat, add basil, finish with parmesan. Serve immediately.
Notes
- Brown the sausage deeply — pale grey sausage means no fond and no depth of flavor. - Always deglaze the pan — those browned bits are concentrated flavor, never waste them. - Make ahead — this sauce is significantly better the next day as the fat fully integrates.
