30-Minute Baked Ziti with Sausage and Zucchini

Steps

1. 1

   Preheat oven and start waterOven 400°F / 205°C

   • Preheat your oven to 400°F (200°C).
   • Bring a large pot of salted water (about 4 quarts / 4 liters) to a rolling boil over high heat.
   • This usually takes 3–4 minutes once the burner is on.

   Ready when: Water is at a rolling boil with large bubbles breaking the surface continuously

   Tip: Adding salt to the water helps season the pasta from within and prevents it from sticking

2. 2

   Cook the ziti

   • Add the ziti to the boiling water and stir well with a wooden spoon to separate the strands.
   • Cook for 1 minute less than the package directions (usually 8–9 minutes total).
   • The pasta should bend slightly but still have a slight firmness in the center, as it will continue cooking in the oven.

   Ready when: Pasta is flexible and just tender, with a firm center when bitten

   Tip: Undercooking the pasta by 1 minute is critical—it will finish cooking in the oven and won't turn to mush

3. 3

   Brown the Italian sausage

   • While the pasta cooks, heat the olive oil in a large skillet (12-inch is ideal) over medium-high heat.
   • Once the oil is shimmering, add the sausage, breaking it into small bite-sized pieces with a wooden spoon.
   • Let it sit undisturbed for 1–2 minutes, then stir and continue cooking for 4–5 more minutes until the pieces are light brown throughout with no pink remaining.

   Ready when: Sausage is light brown and crumbly with no pink inside

   Tip: Breaking sausage into small pieces ensures it cooks quickly and distributes evenly throughout the final dish

4. 4

   Add zucchini and garlic

   • Add the diced zucchini and minced garlic directly to the sausage in the skillet.
   • Stir well and cook over medium-high heat for 2–3 minutes, stirring occasionally, until the zucchini softens slightly and the garlic becomes very fragrant and pale golden.

   Ready when: Zucchini is just beginning to soften; garlic is fragrant and light golden

   Tip: Don't cook the zucchini too long now—it will continue softening in the oven, so slightly undercooked is better

5. 5

   Add the marinara sauce

   • Pour the entire container of marinara sauce into the skillet with the sausage and zucchini.
   • Stir well with a wooden spoon to coat everything evenly.
   • Taste the mixture and season with salt and freshly ground black pepper to your preference.

   Ready when: Sauce coats all ingredients evenly

   Tip: Building the sauce in the skillet before mixing with pasta ensures even distribution and saves cleanup

6. 6

   Combine pasta with sauce

   • Drain the cooked pasta in a colander, reserving about ½ cup (120 ml) of the starchy cooking water.
   • Add the drained pasta directly to the sauce mixture in the skillet.
   • Toss everything together gently using two wooden spoons or forks, lifting from the bottom to coat all the pasta.
   • If the mixture looks dry, add a splash of reserved pasta water—the starch helps the sauce cling to the noodles.
   • Taste and adjust salt and pepper if needed.

   Ready when: All pasta is evenly coated with sauce and meat mixture

   Tip: Pasta water's starch is key—it helps emulsify and thicken the sauce rather than letting it pool at the bottom

7. 7

   Transfer to baking dish

   • Pour the entire pasta and sauce mixture from the skillet into a 9×13-inch (23×33 cm) baking dish.
   • Use a spatula to scrape any stuck bits from the skillet into the dish.
   • Spread everything evenly with the back of a spoon or spatula, distributing the sausage and zucchini throughout.

   Ready when: Pasta mixture is spread in an even layer

   Tip: A dark or nonstick baking dish will give you slightly more crispy, browned edges on the finished dish

8. 8

   Add cheese topping

   • Sprinkle the shredded mozzarella cheese evenly over the entire pasta mixture in an even layer.
   • Then sprinkle the grated Parmesan cheese over the top.
   • Make sure the cheese reaches all the way to the edges of the dish so you get some nicely browned, crispy bits.

   Ready when: Cheese is distributed in an even layer over the top

   Tip: Using both mozzarella and Parmesan creates excellent flavor and texture—the Parmesan adds sharpness and crisps up beautifully

9. 9

   Bake until bubbly and goldenOven 400°F / 205°C

   • Place the baking dish in your preheated 400°F (200°C) oven.
   • Bake for 12–15 minutes, until the cheese is fully melted, bubbling around the edges, and has light golden or light brown spots across the top.
   • If the cheese isn't golden at 12 minutes, check again at 14 minutes.
   • Watch carefully so it doesn't burn—if your oven runs hot, start checking at 11 minutes.

   Ready when: Cheese is fully melted and bubbling; top has light golden or light brown spots

   Tip: If your oven runs hot or cooks unevenly, rotate the dish halfway through baking for more even browning

10. 10

    Rest and serve

    • Remove the baking dish from the oven and let it rest for 2–3 minutes at room temperature.
    • This allows the cheese to set slightly and the pasta to firm up, making serving easier and preventing a watery bottom layer.
    • If using fresh basil, chop it finely and sprinkle over the top just before serving.

    Tip: Don't skip the rest—a brief pause prevents the pasta from seeming dry at the bottom of the dish
