Turn the heat down to low. Add cooking wine to deglaze the pan. Cook for at least 20 minutes or until onions become a deep caramel-brown. Stir every 5 minutes to encourage even browning.
Mushroom Mixture:
To a saucepan, add water and bring to a simmer
Add paprika, garlic powder, and black pepper. Allow to simmer for 1 minute.
Add in sliced mushrooms and cook on medium heat until they become soft.
Add Balsamic vinegar and cook for 1-2 minutes on medium heat.
Drain the mushrooms and save the hot liquid.
Garlic White Sauce:
To a blender, add the cottage cheese, garlic cloves, salt, and black pepper. Then, add 2-3 T of hot mushroom liquid from the previous step. Blend until completely smooth. Add more hot liquid, if needed, to make it smoother.
Assemble Flatbread:
Lay the flatbread on a sheet pan. Spread the Garlic White Sauce all over the top.
Add Mushroom Mixture on top of the sauce.
Next, add a thin layer of Caramelized Onions over the mushrooms.
Finally, top with fresh mozzarella cheese.
Bake or air fry at 400-degrees F for 10-15 minutes.
Slice into 8 slices, top with chopped parsley and drizzle with Balsamic glaze. Enjoy!
Notes: You can broil for 1 minute at the end of the baking time to make the cheese extra bubbly. Use any variety of mushrooms that you like.
