Prep time: 10 minutes. Bake time: 35 to 45 minutes. Total time: approximately 45 to 55 minutes, plus cooling. Yield: 1 small loaf, approximately 8 slices. Oven temperature: 350°F (175°C). Use an 8 by 4-inch loaf pan lined with parchment paper. Ingredients: one 15-ounce can navy beans, drained and rinsed; 4 large eggs; and 2 teaspoons baking powder. Optional seasonings: 1/4 teaspoon salt, 1/2 teaspoon garlic powder, and 1/2 teaspoon dried Italian herbs. Drain and rinse the beans thoroughly, then pat dry. Blend beans and eggs until completely smooth. Add baking powder and blend briefly. Stir in optional seasonings. Pour into prepared loaf pan, smooth the top, and bake for approximately 35 to 45 minutes until lightly golden and set in the center. A toothpick should come out without wet batter; the center should reach approximately 200°F (93°C). Cool in the pan for 10 minutes, then transfer to a wire rack and cool completely before slicing. This bread has a naturally moist, dense texture rather than the airy crumb of conventional yeast bread. Toasting creates a firmer golden surface and improves the eating texture. Serve with avocado, hummus, cream cheese, eggs, or other savory toppings. For strict gluten-free preparation, verify that the navy beans and baking powder are gluten-free and free from relevant cross-contact. Refrigerate fully cooled bread promptly in an airtight container at 40°F (4°C) or colder for up to 4 days. Freeze individual slices with parchment between them for approximately 2 months for best quality. Do not store this moist egg-based loaf at room temperature for extended periods. Estimated nutrition is per slice, assuming 8 slices and no optional seasonings or toppings. Exact values depend on the drained bean weight, egg size, baking powder brand, and slice thickness. The term high-protein is descriptive of the ingredients rather than a verified regulatory protein-content claim.
