Step-by-Step Instructions

1. Preheat and Prepare the Pasta

1. Preheat oven to 375°F.

2. Bring a large pot of water to a rolling boil. Add kosher salt.

3. Cook ziti until very al dente, about 1–2 minutes less than package instructions (usually 7–8 minutes).

4. Drain and set aside. Do not rinse.

Undercooking the pasta ensures it finishes cooking perfectly in the oven without becoming soft.

2. Brown the Sausage

1. Heat olive oil in a large skillet over medium heat.

2. Add sausage and cook, breaking it up with a wooden spoon, until fully browned and slightly caramelized, about 6–8 minutes.

3. If excess grease accumulates, spoon off all but about 1 tablespoon.

Deep browning adds essential flavor to the sauce.

3. Build the Tomato Sauce

1. Add diced onion to the skillet and cook until softened, about 4 minutes.

2. Stir in garlic, oregano, and red pepper flakes; cook 30 seconds until fragrant.

3. Add crushed tomatoes and tomato sauce. Season with salt, pepper, and sugar if needed.

4. Simmer uncovered for 10–15 minutes, stirring occasionally, until slightly thickened.

The sauce should coat a spoon and smell rich and savory.

4. Add the Spinach

1. Stir fresh spinach into the sauce.

2. Cook 2–3 minutes until wilted.

3. Remove from heat.

Spinach reduces significantly and distributes evenly throughout the sauce.

5. Make the Ricotta Mixture

In a medium bowl, combine:

• Ricotta

• Egg

• Parmesan

• 1 cup mozzarella

Mix until smooth and creamy.

The egg helps bind the cheese layer for structure and creaminess.

6. Assemble the Baked Ziti

1. Lightly grease a 9×13-inch baking dish.

2. Toss cooked ziti with the sausage-spinach sauce until evenly coated.

3. Spread half the pasta mixture in the dish.

4. Spoon half the ricotta mixture evenly over the pasta.

5. Add remaining pasta mixture.

6. Top with remaining ricotta mixture.

7. Sprinkle remaining 1 cup mozzarella over the top.

Layering ensures pockets of creamy cheese rather than a dense mixture.

---

7. Bake Until Golden

1. Cover loosely with foil and bake for 20 minutes.

2. Remove foil and bake another 10–15 minutes, until cheese is melted and lightly golden.

3. For deeper browning, broil 1–2 minutes, watching carefully.

4. Let rest 10 minutes before serving.

Resting allows the baked ziti to set for clean slices.
