Notes
Tips and Tricks
Brown the Sausage Well – Let the sausage develop a nice brown color before adding the onions. This adds more depth to the sauce. Don’t Rush the Simmer – The recipe calls for at least an hour of simmering, but 90 minutes to 2 hours makes the sauce even better. Just stir it frequently and add a little water if it gets too thick. A large, heavy-bottomed saucepan distributes heat evenly and prevents the sauce from burning on the bottom during the long simmer. Use Quality Tomato Products – Since tomatoes are the base of this sauce, using good-quality canned tomatoes makes a noticeable difference in flavor. Taste and Adjust – Before serving, taste the sauce and adjust the seasonings. You might want to add more salt, red pepper flakes, or a pinch of sugar to balance the acidity. Cook Pasta Al Dente – Cook the spaghetti until it’s just barely tender. It should have a slight bite since it will continue to soften when mixed with the hot sauce. Reserve Pasta Water – Save a cup of the starchy pasta water before draining. You can add a splash to the sauce if it’s too thick or to help the sauce stick to the noodles better. Let It Rest – If you have time, let the finished sauce sit for 10 to 15 minutes before serving. This helps the flavors settle and the sauce thickens slightly.Storing
Refrigerate – Store the sauce and pasta separately in airtight containers in the refrigerator for up to 4 days. Freeze the Sauce – Freeze the sauce in freezer-safe containers or bags for up to 3 months. Don’t freeze cooked pasta as it gets mushy. Portion for Easy Meals – Divide the sauce into individual portions before freezing so you can thaw only what you need.Reheating
Reheat on Stovetop – Place the sauce in a saucepan over medium-low heat. Stir occasionally and add a splash of water or broth if the sauce is too thick. Heat until warmed through. Reheat in Microwave – Place a serving of sauce in a microwave-safe bowl. Cover loosely and heat in 1-minute intervals, stirring between each, until hot. Reheat Pasta – Drop the cooked pasta in boiling water for 30 seconds to 1 minute, then drain and top with reheated sauce.Nutrition
