1-First Step: Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil and cook the ziti pasta according to package directions until al dente. Drain and set aside.

2-Second Step: In a large skillet, heat 2 tablespoons olive oil over medium heat and sauté 1 medium onion (finely diced) and 3 cloves garlic (minced) until fragrant, about 1 minute. Add 1 pound bulk Italian sausage and cook until browned.

3-Third Step: Combine the cooked pasta, 2 (24-ounce) jars marinara sauce, 1 teaspoon dried Italian seasoning, 1 (15-ounce) container whole milk ricotta cheese, 1/2 cup grated parmesan cheese, and half of the 1 (8-ounce) package shredded mozzarella cheese in a large mixing bowl. For vegan or low-calorie adaptations, substitute plant-based cheeses or low-fat alternatives here.

4-Fourth Step: Transfer the pasta mixture into a greased baking dish. Sprinkle the remaining shredded mozzarella evenly over the top.

5-Fifth Step: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.

6-Final Step: Let the baked ziti rest for 5-10 minutes before serving. Garnish with fresh basil or parsley if desired. For dietary modifications, consider adding sautéed vegetables or plant-based protein during mixing for added flavor and nutrition.
