1 tablespoon olive oil, plus more for drizzling over pasta
1 pound Italian sausage
32 oz Marinara Sauce
15 oz ricotta cheese
1 large egg
2 cups mozzarella cheese, divided
3/4 cups shredded Parmesan cheese, divided
2 tablespoons chopped fresh basil
1 teaspoon Italian seasoning
Dash of crushed red pepper flakes, optional
Kosher salt and black pepper, to taste
For garnish: chopped basil, if desired
Preheat oven to 375°F. Spray a 9×13-baking dish with cooking spray and set aside.
Prepare Liviva Shirataki Pasta by rinsing well, and using a little bit of olive oil in a pan to heat up the pasta and set aside.
Meanwhile, in a large sauté pan, heat the oil over moderate heat. Add the Italian sausage and cook, breaking up the meat with a wooden spoon, until it is no longer pink, about 5 to 7 minutes. Discard the excess fat and set aside.
In a medium bowl, mix together the ricotta, egg, 1 cup mozzarella cheese, ½ cup Parmesan cheese, basil, Italian seasoning, and crushed red pepper flakes, if using. Season with salt and pepper.
Add the ricotta mixture to the pasta. Add the marinara sauce, cooked sausage, and stir until combined, stirring gently to not break up the pasta noodles.
Pour the pasta into the prepared pan and top with the remaining 1 cup mozzarella cheese and ¼ cup Parmesan cheese.
Bake for 25 to 30 minutes or until cheese is golden brown and the pasta is bubbly. Remove from the oven and let sit for 5 minutes. Garnish with fresh basil, if desired, and serve warm.
