Preheat the oven to 350°F (180°C) and grease the loaf pan with butter or non-stick spray. Prepare ingredients by mashing bananas in a large mixing bowl and chopping strawberries into small pieces.
In the same bowl, combine mashed bananas, melted butter, granulated sugar, and eggs. Whisk until the mixture is smooth and slightly frothy, indicating thorough mixing.
In a separate small bowl, whisk together flour, baking soda, and salt. Gradually add the dry ingredients into the wet mixture, folding gently with a spatula until just combined, avoiding overmixing.
Gently fold chopped strawberries into the batter, distributing evenly without crushing the berries to retain their shape.
Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Bake in the preheated oven for about 60 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The edges may slightly pull away from the pan when done.
Remove the loaf from the oven and allow it to cool in the pan for 10 minutes. Then, transfer to a wire rack and cool completely before slicing to reveal a moist crumb speckled with strawberries and a golden crust.
