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!
