Half red sauce, half Alfredo sauce, and a whole lotta flavor!
In a large pot of salted boiling water, cook the linguine according to package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Add minced garlic and crushed red pepper flakes, sauté for 1-2 minutes until fragrant. Add crushed tomatoes, Italian seasoning, salt, and black pepper. Simmer for 10-15 minutes.
In another saucepan, combine heavy cream and Parmesan cheese over medium heat. Stir until the cheese has melted and the sauce is smooth. Season with salt and black pepper to taste.
In the skillet with the red sauce, add the shrimp and scallops. Cook for about 5-7 minutes until the seafood is cooked through and opaque.
Divide the cooked linguine between plates. Spoon the red sauce seafood mixture on one half and the Alfredo sauce on the other half. Garnish with fresh parsley and serve immediately.
