Steps
Tap an underlined word for a quick explanation.
the oven to 450°F and brush a with 1 teaspoon oil.
Preheat. Preheating means turning the oven on before you start, so it’s fully hot when the food goes in. Food that starts in a cold oven cooks unevenly and doesn’t brown the same.
How you’ll know: The oven beeps or its light clicks off, usually 10 to 15 minutes after you turn it on.
Sheet pan. A sheet pan is a flat metal baking tray with a low rim all the way around. The rim catches juices, and the wide surface lets food spread out and brown.
How you’ll know: Everything fits in one layer with a little space between the pieces.
the onion as thinly as you can.
Slice. Slicing means cutting food into flat pieces of about the same thickness. Even slices cook evenly, so none are raw while others burn.
How you’ll know: Lay a few side by side: they’re close to the same thickness from one end to the other.
Dolly’s tip: Thin is the point. Thick onion slices stay raw on a crust this quick.Unroll the dough onto the pan and stretch it as thin as you can to fill the pan.
Dolly’s tip: If it keeps shrinking back, give it 5 minutes to relax and try again.Stir the sour cream with ¼ teaspoon salt and the pepper and spread it thinly all the way to the edges.
Scatter the onion and cheese evenly over the top.
12 to 15 minutes, until the edges are and browned in spots and the onions are tender.
Bake. Baking means cooking in the oven with dry heat all around the food. It cooks evenly from every side, so you can mostly leave it alone.
How you’ll know: It’s golden on top and passes the recipe’s check, like a clean toothpick or the right temperature.
Crispy. Crispy means the outside is dry, firm and crunchy. It comes from high heat, a little oil and room in the pan, because crowded food steams and goes soft.
How you’ll know: It sounds crunchy when you tap or bite it, and it doesn’t flop when you lift it.

the arugula with the lemon juice, the rest of the oil and the last of the salt.
Toss. Tossing means gently lifting and turning food so everything gets coated, like pasta in sauce or vegetables in oil. It coats every piece evenly without mashing anything.
How you’ll know: Every piece looks glossy or evenly coated, with no dry spots hiding underneath.
Scatter the chives over the flammkuchen, cut it into squares and serve with the salad.
