Hey there, pasta lover—let's get started! Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with a little olive oil so nothing sticks.

Bring a large pot of salted water to a boil and cook the ziti for about 7-8 minutes (just shy of al dente—it'll finish in the oven for perfect texture). Drain and set aside.

While the pasta cooks, heat olive oil in a large skillet over medium-high heat. Add the crumbled Italian sausage and cook, breaking it up with a spoon, until browned and cooked through (about 8-10 minutes).

Toss in the chopped onion and minced garlic—sauté for 4-5 minutes until softened and fragrant. Your kitchen is going to smell incredible right now!

Pour in the marinara sauce, stir in Italian seasoning, salt, and pepper. Let it simmer gently for 5 minutes to meld those flavors—taste and adjust if needed.

In a bowl, mix the ricotta with the egg, a pinch of salt, and ½ cup Parmesan—this creamy mixture is the secret to those luscious pockets!

Time to layer! Spread half the cooked ziti in the baking dish, dollop half the ricotta mixture over it, then pour half the sausage sauce on top. Sprinkle with 2 cups mozzarella.

Repeat the layers: remaining ziti, remaining ricotta, remaining sauce, and finish with the last 2 cups mozzarella plus remaining ½ cup Parmesan for that golden, bubbly top.

Cover with foil and bake for 25 minutes, then uncover and bake another 15-20 minutes until the cheese is melted, bubbly, and lightly golden—pure magic!

Let it rest for 10-15 minutes (patience pays off!), garnish with fresh basil or parsley, and serve hot—grab a big spoon and enjoy every cheesy, saucy bite!
