Easy Italian Sausage Pasta Sauce, Slow-Simmered

A rustic meat sauce built on browned Italian sausage, aromatic garlic and onion, and whole canned plum tomatoes simmered for over an hour. The sauce develops deep savory notes from the sausage fat and tomato paste while bay leaf and dried Italian herbs add backbone. Spicy or sweet sausage variations suit weeknight dinners or casual entertaining; serve over any pasta shape or polenta. This version prioritizes low-fuss technique and minimal ingredients, letting quality sausage and slow cooking do the work.

Tips
Rub dried Italian seasoning between your fingers before adding to release aromatic oils and deepen flavor impact.
Brown the sausage thoroughly on all sides; this builds fond that enriches the sauce base.
Stir frequently during simmering to prevent scorching and encourage even melding of flavors.
Good to Know
Refrigerate up to 4 days in an airtight container. Freeze up to 3 months in freezer bags or containers.
Make the entire sauce 1-2 days ahead and refrigerate. Reheat gently over medium-low heat, stirring occasionally, before serving.
Spoon over freshly cooked pasta. Garnish with grated Parmesan, red pepper flakes, or fresh parsley. Pair with a medium-bodied red wine like Chianti or Sangiovese.
Common Mistakes
Do not skip browning the sausage to avoid a pale, less flavorful sauce.
Do not drain the canned tomatoes to avoid a sauce that is too thick and concentrated.
Do not omit the bay leaf removal to avoid a bitter or overpowering herb note.
Do not rush the simmer to avoid insufficient flavor development and melding.

FAQ
Can I use ground Italian sausage instead of links?
Yes. Brown 1 pound of ground sausage, breaking it apart with a spoon, for about 5-7 minutes. Proceed with the recipe as written. You may skip the cooling and slicing step.
What if I prefer a thinner sauce?
Simmer uncovered instead of partially covered to allow more evaporation, or add 1/2 to 1 cup of pasta water, broth, or red wine to reach your desired consistency. Adjust salt and seasoning accordingly.
Can I freeze this sauce and for how long?
Yes, freeze up to 3 months in freezer-safe containers or bags. Thaw overnight in the refrigerator and reheat gently over medium-low heat, stirring occasionally, until warm throughout.
