Instructions

Cottage Cheese or Ricotta Cheese Mixture

Place cottage cheese, 1/2 cup mozzarella, 1/4 cup parmesan, Italian seasoning, basil, garlic powder, onion powder, salt, pepper, and eggs into a food processor.  Process until combined. It's okay if it's still a little chunky.
Pulse in spinach until it’s incorporated, then set aside.

Seafood Alfredo

Place shrimp, scallops, and crab into a medium sized bowl, then stir in the alfredo sauce.
Taste and re-season, if necessary, then set aside.

Assembly

Pre-heat oven to 350 degrees F and grease a 9x13 inch baking dish with cooking spray.
Spread 1 1/2 cups of seafood alfredo in the bottom of the prepared baking dish.
To assemble: repeat the below steps (step 4 - step 8) 4 times.
Layer 4 noodles lengthwise - they will overlap slightly - that's ok.
Spread with 1/4 of the cottage cheese mixture.
Top with a 1/2 cup mozzarella cheese.
Spoon 1 1/2 cups seafood sauce over mozzarella.
Sprinkle with 1/4 cup Parmesan cheese.
Once the layers are complete, top with remaining 1 cup mozzarella.
Cover the baking dish with tin foil that’s been sprayed with cooking spray (this prevents the cheese from sticking), then bake in the preheated oven for 45 minutes.
Uncover and bake for an additional 15-20 minutes, or until the cheese has melted and the sauce is bubbly.
Remove from the oven, then cool for 20 minutes before slicing and serving!
