Step-by-Step Cooking Instructions & Timings
Step 1: Prep & Preheat
-
Time: 3 minutes | Intensity: Low
-
Preheat your oven to 375°F (190°C).
-
Lightly grease a 13×9-inch baking dish with non-stick cooking spray or a drizzle of olive oil.
Step 2: Cook the Pasta
-
Time: 10 minutes | Intensity: Low to Medium
-
Bring a large pot of heavily salted water to a rolling boil over high heat.
-
Add the ziti pasta and cook for approximately 8–9 minutes, or until it reaches a firm al dente texture. (Note: The pasta will continue cooking in the oven, so slightly undercooking it keeps it from getting soggy).
-
Drain the pasta completely in a colander and set aside.
Step 3: Mix the Cheese Filling
-
Time: 4 minutes | Intensity: Low
-
In a large mixing bowl, combine the ricotta cheese, 1 cup of shredded mozzarella cheese, 1/4 cup of grated Parmesan cheese, the egg, Italian seasoning, garlic powder, onion powder, salt, and black pepper.
-
Stir thoroughly until the mixture is smooth and fully blended.
Step 4: Combine Pasta, Sauce, and Cheese
-
Time: 3 minutes | Intensity: Low
-
Pour the drained pasta into the mixing bowl with the ricotta blend.
-
Add about 3/4 of the jar of marinara sauce (reserve the remaining 1/4 jar for assembly).
-
Gently fold everything together until the pasta is coated in sauce and cheese.
Step 5: Assemble the Casserole
-
Time: 3 minutes | Intensity: Low
-
Spread the reserved marinara sauce evenly across the bottom of the prepared 13×9-inch baking dish.
-
Pour the cheesy ziti mixture into the dish, spreading it out into an even layer.
-
Sprinkle the remaining 1 cup of mozzarella cheese and 1/4 cup of Parmesan cheese evenly across the top.
Step 6: Bake to Perfection
-
Time: 20 minutes | Intensity: Passive / Low
-
Cover the baking dish tightly with aluminum foil to trap moisture.
-
Bake in the preheated oven at 375°F (190°C) for 15 minutes.
-
Carefully remove the foil and bake uncovered for an additional 5–10 minutes, until the top cheese is fully melted, bubbling, and lightly golden.
Step 7: Rest & Serve
-
Time: 5 minutes | Intensity: Passive
-
Remove the dish from the oven and let it rest for 5 minutes before serving. This allows the cheeses to set so the casserole serves cleanly.
-
Garnish with freshly chopped basil or parsley, serve warm, and enjoy!
Recipe Customizations & Variations
-
Add Meat: To make this dish heartier, brown 1 lb of ground Italian sausage, ground beef, or turkey, drain the excess fat, and stir it into the pasta and sauce mixture before baking.
-
Add Veggies: Fold in sauteed mushrooms, fresh spinach, or diced bell peppers for added nutrients and color.
-
Make It Spicy: Add 1/2 teaspoon of crushed red pepper flakes to the ricotta mixture or use a spicy Arrabbiata marinara sauce.
Storage & Reheating Instructions
-
Refrigeration: Store leftover Lazy Day Ziti in an airtight container in the refrigerator for up to 4 days.
-
Freezing: Assemble the dish up to Step 5 (before baking), wrap tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as instructed.
-
Reheating: Reheat individual portions in the microwave for 1.5–2 minutes, or heat the whole casserole covered in an oven preheated to 350°F (175°C) for 20 minutes until warmed through.
