This baked ziti with sausage is family favorite. The sauce for this easy recipe is made with Italian sausage, it adds a ton of flavor so we can keep the rest of the ingredients to a minimum. We also cheat a little by using jarred pasta sauce and canned tomatoes, but add onions and a bunch of garlic for extra flavor. Then the sauce is simmered to give it a homemade taste. Then of course there’s the cheese…a lot of cheese!

Ingredients
- Olive Oil – we used extra virgin because it’s what we had on hand but regular and extra light will work too.
- Aromatics – onions and garlic add extra flavor and give the Italian sausage sauce that homemade taste.
- Italian Sausage – we use mild Italian sausage links with the casings removed and torn into pieces, you can also use bulk sausage and if you like it spicy use hot Italian sausage.
- Tomatoes – use canned diced tomatoes, regular or fire roasted. You can also use canned whole tomatoes and chop them up with kitchen shears.
- Pasta sauce – use your favorite brand but make it a meatless variety so nothing is competing with the sausage.
- Pasta – Ziti, it’s in the name
- Salt – for the pasta water, we use kosher salt
- Cheese – Mozzarella and parmesan cheese
- Garnish and serving – chopped parsley, parmesan cheese and crushed red pepper for a little zing, if desired.

Recipe tips
- Don’t overcook the pasta; cook it only to al dente. It will continue cooking once it’s drained plus it’s going into the hot sauce. If the ziti is overcooked it will get mushy
- Break up the Italian sausage before cooking it. Large pieces will be difficult to break up once they hit the hot pan.
- All sausage is different and some may be fattier than others. If you feel that the sausage has rendered too much grease, drain some. An easy way to do this is to take the pot off the heat. Mound the sausage to one side of the pot and gently tip it so that the excess oil pools on the other side of the sausage. Use a ladle or a large spoon to scoop some out.
- Reserve about 1 cup of the pasta cooking water before draining. You can use the pasta water to loosen the sauce a little bit if it’s too thick. Just add a little at a time while stirring until it reaches the desired consistency.
- Keep the sauce at a simmer after it’s covered. Lower the heat if it’s boiling too vigorously. This is especially important after the sauce starts to thicken. Also, give it a good stir occasionally to keep it from sticking and burning on the bottom.

Instructions
Heat the olive oil in a large, heavy pot or a large, deep skillet over medium heat. When the oil is hot, but nowhere near smoking, add the onions. Cook them for 3 minutes, stirring frequently.
Next, add the garlic and cook for 1 minute, stirring frequently.
Add the sausage to the pot and raise the heat to medium-high. Cook for 5-6 minutes until the sausage is browned. Stir frequently, while breaking up any large sausage pieces using a wooden spoon or a spatula.

Add the diced tomatoes and pasta sauce to the pot and stir well. Bring the sauce to a simmer, lower the heat to medium-low and cover.
Cook the sauce for 40-45 minutes to let it thicken and allow the flavors to come together. Stir the sausage tomato sauce occasionally, especially as it starts thickening. Keep it at a simmer, if it starts boiling too vigorously lower the heat a bit.

Preheat oven to 350°F
While the sauce cooks, start the pasta. Cook the ziti to package directions for al-dente. Drain the ziti well and set aside.
Build the casserole
Combine the ziti and the sauce in the larger of the two pots. Gently stir to mix well.
Use a large, oven proof casserole dish or baking pan (approximately 9×13 inch).
Spoon half of the pasta mixture into the casserole dish. Sprinkle with half the mozzarella cheese and half the parmesan cheese. Add the remaining pasta and top with the remaining mozzarella and parmesan cheeses.

Place the casserole dish on a rimmed baking sheet, just in case it bubbles over. Bake the pasta for 15-20 minutes until the cheese is melted. Garnish the Italian sausage baked ziti with a little chopped parsley and serve with extra parmesan cheese and crushed red pepper, if desired.

Fantastic recipe! I compared several similar recipes and did tweak things a bit but I used yours as my main framework. Made a triple batch to bring to an Italian luncheon. I hardly had any left over! My family requested it after enjoying the leftovers. Then I brought a big batch as my Meal Train meal for a friend. We used our Venison Italian Sausage for each batch. It was pretty spicy and very tasty! Thank you!

An hour make this dish ahead of time n refrigerate until ready to cook?
Thank you! Karen

Yes you can, just leave it out at room temperature for just a few minutes to get the chill out of the baking dish. Some dishes do not do well with extreme changes in temperature.
