"To those below that are trying to use dried basil, the 1 cup basil would be fresh basil. If using dried, I'd use about 1 T."

"My family and I do not like mushrooms or bell pepper so I kept them out but even without them the dish tasted super delicious.

vickystick-I used dried basil and I didn't have enough for 1 cup so it was about 3/4 cup and it did seem like a lot at first but once I put in the spaghetti it came out fine."

"I love this but I have a question about the basil. It calls for 1 cup. I bought dried basil. That seems like way too much. The spice bottle doesn't even have 1 cup in it. Can someone please help!"

"Awesome, simply awesome. I made this last night for dinner, and it was an instant hit. It takes approximately 30 to 45 min to prep, but after that, it's a breeze. I'll probably make this twice a month..."
