I found this recipe on 'Dutch Oven Madness' blog but it was for a 14" DO. So I decided to try cutting it down for a 12" DO (cuz that's all I have right now
I don't think I got my oven up to the 400 degrees called for so it took longer that the 15-20 minutes called for in the original recipe (mine took about 50 min). It turned out very good though. I think I'm a bit more confident now when it comes to 'tweaking' recipes

Also, preheating the DO lid is important.

Cheese Stuffed Focaccia
( for 12" dutch oven)
10 ½ oz (1 cup 2.5oz) warm water
1 ½ Tbs active Dry Yeast
4 ½ Tbs Butter
3 Tbs nonfat Dry Milk powder
4 ½ Tbs Sugar
2 ¼ tsp Salt
4 ½ cups Flour
2 Tbs Olive Oil
7 slices provolone cheese
7 oz shredded mozzarella
1 Tbs dried Basil, divided
1 tsp dried Oregano
1 1/2 tsp. dried Rosemary
1 1/2 tsp. dried Thyme
2 cloves minced Garlic
1/2 cup fresh Parmesan cheese, shredded
In a bowl, combine the water and yeast. Allow to sit for 5 minutes
Add butter, milk, sugar, salt and flour and knead well. Cover and let rest for 15 minutes
Knead for 1 minute. Roll out half of the dough into a 12 inch circle. Put dough in the DO and press it up the sides just a little. Brush with 1 Tbs. olive oil.
Cover with Provolone and Mozzarella cheeses. Sprinkle cheeses with Oregano, Rosemary, Thyme, Garlic and ½ the Basil.
Roll out remaining dough into a 12 circle and lay on top of the cheese layer; pinch bottom and top layers together.
Brush with remaining oil and sprinkle with Parmesan cheese and remaining Basil.
Bake at 400° until slightly browned. Important to preheat the lid.
I used 19 coals on top and 10 coals on bottom for 12”. This took about 50 minutes. I rotated the DO and the lid every 10 minutes. At about 30 minutes, I removed the DO from the bottom coals and placed the bottom coals on the lid, to help brown the top a bit more. Turned out good....like stuffed pizza...could use pepperoni or salami in the middle in place of some of the cheese. Would be really good to dip it in a heated marinara sauce when serving.
Happy cooking!
