Press the dough down and stretch it onto the lined baking sheet to about ½ inch thick.
Make deep dimples in the dough with your fingers
Arrange the tomato slices over the dough. Spoon the garlic herb oil over the tomatoes and into the dimples.
Bake for 10 minutes.
Sprinkle the Parmesan over the focaccia.
⅓ cup Parmesan cheese
Bake for 5 to 10 minutes more, until the focaccia is golden brown and the edges are crisp.
Let it cool slightly before slicing.
NOTES
1. Can I knead this by hand? Yes. The dough is sticky, so lightly oil your hands instead of adding lots of extra flour. A mixer with dough hooks or a bread machine makes it easier.2. How do I know if my yeast is active? After 5 minutes in lukewarm water with sugar, you should see bubbles on top. If nothing happens, your yeast may be too old.3. Can I use cherry tomatoes instead of Roma tomatoes? Yes. Cut them in halves or slices. Roma tomatoes are less watery, but cherry tomatoes work well too.4. Why is my focaccia dense? It usually needs more kneading or more rise time. The dough should rise in a warm spot until doubled.5. Can I make this in a deeper pan? Yes. It will bake up thicker and softer. A baking sheet gives you a flatter focaccia with more crisp edges.6. Storage
Refrigerator I do not recommend storing focaccia in the fridge. The bread loses its soft texture quickly.
Freezer Bake the focaccia for about 15 minutes without the Parmesan. Let it cool, wrap it well, and freeze for up to 2 months.
Reheating from Frozen Bake the frozen focaccia at 460 °F for 10 minutes. Add the Parmesan and bake for 6 more minutes, until warm and golden.
Reheating Fully Baked Focaccia Warm slices in a hot oven for a few minutes, until the edges are crisp again.
