Preheat oven to 400F.

Cook fettuccine pasta according to package directions.

Drain pasta and place in a large bowl.

Add thawed frozen peas to the bowl with the pasta.

In a small bowl, beat egg yolks.

Add half-and-half, butter, grated parmesan cheese, parsley, basil, onion powder, and black pepper to the egg yolks.

Stir the sauce mixture into the noodles and peas, ensuring it is well mixed.

Pour the pasta mixture into a 3 quart shallow baking dish.

Cover the dish tightly with greased foil.

Bake in the preheated oven until hot, approximately 20 to 25 minutes.
