Preheat the oven to 400° F.In a 9×13 inch baking dish, combine the olive oil, garlic, shallots, basil, paprika, chili flakes, salt, and pepper. Add the dry orzo, artichokes, and pesto. Pour over 2 1/4 cups of water and stir to combine. Place the spinach on top. Bake for 12-15 minutes, until most of the water has cooked into the pasta, but not all of it.Stir the pasta around, then sprinkle the cheeses overtop. Bake another 10 minutes, until the cheese has melted and the sauce is bubbling. If there's a lot of oil from the pesto on top, drain off the excess. Top with fresh basil!
