In a large skillet over medium heat, cook 1 pound lean ground beef until browned and no longer pink. Drain excess fat if needed.
Add 1 cup diced onion and cook until softened, about 4 minutes.
Stir in 1 teaspoon minced garlic, 1 teaspoon basil, and 1 teaspoon oregano and cook for another minute until fragrant.
Pour 48 ounces of pasta sauce into the skillet with the beef mixture. Stir well to combine, allowing the flavors to meld over low heat for a few minutes.
In a medium bowl, mix 1 cup ricotta cheese, 1 cup parmesan cheese, and 1 cup of shredded mozzarella cheese.
Spray the inside of your crockpot with non-stick cooking spray.
Add half of the uncooked 16 ounces baked ziti pasta to the bottom of the crockpot.
Spoon half of the meat sauce over the pasta.
Dollop half of the cheese mixture over the sauce, then sprinkle with half of the remaining 1 cup mozzarella cheese.
Repeat the layers with the remaining pasta, meat sauce, cheese mixture, and top with the last cup of mozzarella cheese.
Cover and cook on low for 4 to 5 hours, or until the pasta is tender and the cheese is melted and bubbly.
Avoid lifting the lid too often to maintain heat.
Once cooked, sprinkle generously with chopped fresh parsley for a pop of color and freshness.
Serve hot and enjoy the comforting blend of flavors.
