Adam Richman shares a fun way to serve up spaghetti: Just turn it into pie!
Preheat oven to 350 degrees.
In a large skillet, sauté the onions until soft. Add ground turkey or beef, and ¾ cup of the tomato paste.
Add half the reserved pasta water and stir well. Season with salt, to taste. Consistency should be like a thick Bolognese sauce. Add more cooking water as needed.
In a large bowl, mix together the cooked spaghetti, eggs, parmesan cheese, 1 cup of the mozzarella, and ¼ cup of the tomato paste.
Grease a 9 or 10-inch pie pan with olive oil. Spread half the meat mixture over the bottom of the pan. Add the spaghetti mixture and press it down to level it. Top with the remaining meat mixture, then scatter the remaining mozzarella on top.
Bake the pie in the oven for 30 to 35 minutes. Remove from the oven and let sit about 10 minutes. Use a sharp knife or pizza slicer to cut into wedges like a pie. Serve with a green salad.
