Cook the lasagna noodles according to package directions. Drain and cut into 3” pieces.
While the noodles are cooking, add the Ricotta cheese, cottage cheese, 1 ½ cups Parmesan cheese, garlic salt, Italian seasoning, onion powder, salt and pepper, red pepper flakes, spinach, and artichoke hearts to a large bowl. Mix it together until it’s completely combined. Add lasagna pieces to the bowl, and mix until they’re completely coated in the cheese mixture.
Pour the lasagna mixture onto a half-sheet baking sheet that’s been covered in foil (if desired) and lightly sprayed with cooking spray. Top with remaining parmesan cheese and mozzarella cheese.
Bake for 30 minutes, until the cheese starts to turn golden brown and bubbly.
Notes
We would recommend using regular lasagna noodles (not oven-ready noodles!) for this recipe.
