I used my regular oven and after the 30 min the dish was still very soupy. I gave it another 20 minutes to firm up. I reduced the Feta to 4 oz because that's all I had and I reduced the Kosher salt to 1 tsp because the Feta is quite salty. The end result was delicious and I will make this again, however I only gave it 3 stars because I had to increase the cooking time by so much. Using a toaster oven might make the difference there.
