Preheat oven to 425°F.
Combine 1 cup flour, undissolved yeast, sugar and salt in a large bowl. Add very warm water and oil; mix until well blended, about 1 minute. Gradually add enough remaining flour to make a soft dough. Dough should form a ball and will be slightly sticky. Knead on a floured surface, adding additional flour if necessary, until smooth and elastic, about 4 minutes. Let dough rest for 10 minutes.
Pat dough with floured hands to fill greased pizza pan or baking sheet. OR roll dough on a floured counter to 12-inch circle; place in greased pizza pan or baking sheet. Form a rim by pinching the edge of the dough.
Spread an even layer of creme fraiche & nutmeg over dough. Evenly distribute bacon & onions on top.
Bake on lowest oven rack for 12 to 15 minutes, until crust is browned
Serve with fresh ground pepper to taste. Enjoy!
