I maked baked ziti. I browned the ground beef. I don't recall cutting any pieces open to check for doneness, but it was all brown and I had cooked it for about 10 minutes. I then combined all ingredients in an 8x8 aluminum pan, covered with foil and baked 45 minutes in a pre heated 350 degree oven. If any ground beef was still pink, would the baking have cooked it completely and safe?
