Directions

  1. Prepare the oven and pan

    Heat the oven to 350°F with a rack in the center. Lightly grease a 9-by-5-inch metal loaf pan, line it lengthwise with parchment so two sides overhang, and grease the parchment. Metal conducts heat more predictably than glass for this loaf.

  2. Whisk the dry ingredients

    In a medium bowl, whisk the 1 3/4 cups flour, baking powder, baking soda, and salt for 30 seconds. In a separate small bowl, toss the completely dry blueberries with the remaining 1 tablespoon flour.

  3. Rub the lemon sugar

    Put the granulated sugar and lemon zest in a large bowl. Rub them together with your fingertips for about 30 seconds, until the sugar feels damp and smells strongly of lemon; this releases the zest's aromatic oils.

  4. Build the batter

    Whisk the eggs into the lemon sugar until slightly thickened, then whisk in the yogurt, oil, lemon juice, and vanilla until smooth. Add the dry ingredients and fold with a flexible spatula just until a few flour streaks remain. Fold in the blueberries with no more than six broad strokes.

  5. Top and bake

    Scrape the batter into the pan and smooth the top. Sprinkle evenly with the coarse sugar. Bake for 55 to 65 minutes, rotating after 40 minutes, until the loaf is deeply golden, a skewer comes out without wet batter, and the center registers 200°F to 205°F. Tent loosely with foil if the top darkens before the center is done.

  6. Set the crumb before slicing

    Cool in the pan for 15 minutes, then lift the loaf out by the parchment and place it on a rack. It can be served warm after another 10 minutes, but cool completely for about 1 hour for the cleanest slices. The listed cook time includes the 25-minute cooling period before warm service.

Why this works

Why it worksGreek yogurt supplies moisture and acidity, which activates the baking soda and keeps the crumb tender without creaming butter.
Why it worksDry berries lightly coated in flour stay distributed more evenly and introduce less surface water into the batter.
Why it worksA center temperature of 200°F to 205°F confirms the starches have set even when a skewer happens to miss a pocket of wet batter.

Swaps & notes

Easy swaps

  • Use frozen blueberries straight from the freezer; do not thaw them, fold them in last, and expect 5 to 8 additional minutes of baking.
  • Replace the lemon zest and juice with orange zest and juice for a softer citrus flavor.
  • Use sour cream in place of Greek yogurt by weight; loosen very thick sour cream with 1 tablespoon milk.

Cook notes

  • Weighing the flour is the most reliable safeguard against a dry loaf. If using cups, spoon flour into the cup and level it rather than scooping directly from the bag.
  • Room-temperature eggs and yogurt combine more smoothly with the oil, but do not leave dairy or eggs out for more than 2 hours total.
  • The sparkling sugar is functional as well as decorative: it creates the crisp top shown in the finished loaf.

Storage

Cool completely before storing. Keep the loaf tightly wrapped at room temperature for up to 2 days or refrigerate for up to 5 days. Rewarm individual slices for 8 to 10 seconds in the microwave or 5 minutes in a 300°F oven. Freeze wrapped slices in an airtight container for up to 2 months and thaw at room temperature.

Questions

Why did my blueberries sink?

Wet berries, thin batter, and overmixing all make sinking more likely. Dry the fruit thoroughly, coat it with the measured tablespoon of flour, and fold only until evenly dispersed.

Can I bake this as muffins?

Yes. Divide the batter among 12 lined standard muffin cups, sprinkle with coarse sugar, and bake at 375°F for 18 to 23 minutes until the centers reach about 200°F.

How do I keep quick bread from sticking to the pan?

Grease both the metal pan and the parchment sling, then wait the full 15 minutes before lifting. Removing it immediately can tear the soft sides; leaving it in the pan too long traps steam.
