Cook pasta according to package instructions, preferably al-dente. Reserve 1/2 cup cooking liquid.
Preheat oven to 400 degrees. F. In an oven safe baking dish place tomatoes, salt, pepper, herbs de provence, and onion powder. Drizzle with olive oil and give it a good stir.
Move the tomatoes and olive mixture to make room for the block of feta. Place feta cheese in the center of the baking pan. Bake for 30 min or until tomates burst.
Remove from the oven. Stir the feta and tomato mixture. Add ricotta cheese, grated garlic, and fresh basil. Stir until creamy.
