Preheat oven to 400 degrees.: You will smell a faint warmth in the air as the oven comes up to temperature, and that ready heat is what crisps the edges of the pita while melting the mozzarella cheese . Preheating matters because it ensures even baking start to finish, preventing soggy centers. A common error is skipping preheat, which leads to unevenly melted cheese and limp pita . If your oven runs hot, watch the first batch closely for golden edges.
Place the first 4 ingredients in a bowl to combine.: After combining the tomato sauce , garlic powder , Italian herbs , and kosher salt , inhale the fragrant mix of herbs and garlic; this blend should smell balanced, not sharp. Mixing allows the seasoning to infuse the sauce, so each spoonful will coat the pita uniformly. If the sauce tastes flat, adjust with a pinch more kosher salt . Be careful not to over-season, which can mask the delicate herb notes.
Cover the pitas with 1/4 cup sauce, 1/4 cup cheese and slices of black olives and other desired toppings.: When you spread about 1/4 cup of the seasoned tomato sauce onto each pita , notice the contrast between the sauce’s sheen and the dry surface of the bread. Sprinkle 1/4 cup grated mozzarella cheese so it nests into the sauce, and place sliced black olives on top so they brown slightly rather than sink. This order prevents sogginess and ensures even melting. Avoid piling toppings too high, as that can prevent the pita from crisping and result in a floppy base.
Place on a foil lined cookie sheet and bake for 10 minutes or until cheese is melted.: As the tray goes into the oven you will start to notice a warm, toasty aroma. Around the halfway mark the mozzarella cheese will soften and then begin to bubble and lightly brown at the edges, signaling readiness. Baking on foil makes cleanup simpler and reflects heat for a crisper underside. A frequent mistake is leaving them in too long, which can dry out the pita and make the cheese rubbery. Check at the nine minute mark and remove once the cheese looks glossy and has small golden spots.
Cut and serve.: Right after removing from the oven the cheese will be molten and strings will form when you lift a slice, offering a pleasing pull and aroma. Use a pizza cutter or sharp knife to divide each mini pizza into pieces, and serve while hot so the texture remains at its best. If you wait too long, the mozzarella cheese firms up and the experience changes from gooey to chewy, which some prefer, but it will feel less indulgent. Let the pizzas rest a minute if the cheese is dangerously hot before serving to young diners.
