Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan.
Toss strawberries with 1 tablespoon of flour in a small bowl. Set aside.
In a large bowl, whisk together remaining 2 cups flour, baking powder, baking soda, and salt.
In another bowl, whisk egg and sugar until well combined. Stir in milk, oil, and vanilla until smooth.
Add wet ingredients to dry ingredients and stir just until combined. Do not overmix.
Gently fold in the floured strawberries.
Pour batter into prepared pan and smooth the top.
Bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean. Loosely cover with foil halfway through baking to prevent over-browning.
Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Slice and serve.
Notes
Optional Vanilla Glaze
1 cup powdered sugar
2 to 3 tablespoons heavy cream
½ teaspoon vanilla extract
Whisk all ingredients until smooth, adding more cream if needed. Drizzle over cooled bread and let set before slicing.
To make muffins
Divide batter evenly among the muffin cups, filling each about ¾ full.
Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
Drizzle cooled muffins with the vanilla glaze (see glaze recipe above) and let it set before serving.
Storage
Wrap tightly and store at room temperature for 3 days, or refrigerate for up to 1 week. Freeze for up to 3 months.
