Ingredients
You only need three things:
- 1½ cups (about 250 g) cooked kidney beans, drained and rinsed
- 3 large eggs
- 1 tsp (5 g) baking powder
You’ll also need a little oil or butter, or a sheet of parchment paper, for the loaf pan.
A note on the beans
Canned kidney beans are the easiest option. They are already fully cooked, which matters for safety (see the safety section below). If you cook dried beans yourself, make sure they are boiled until completely soft, then drain and cool them before measuring.
A note on the eggs
Use large eggs at room temperature if you can. Room-temperature eggs blend more evenly into the beans and help produce a smoother batter.
A note on the baking powder
Check that your baking powder is fresh. Old baking powder loses strength, and your loaf may bake up flatter and denser. A quick test is to stir a little into hot water. If it fizzes right away, it’s still active.
Instructions
Preheat your oven to 350°F (175°C).
Lightly grease a small loaf pan, or line it with parchment paper so the loaf lifts out easily later.
Drain the kidney beans and rinse them thoroughly under cold water. This removes the canning liquid and excess salt. Then pat the beans gently with a clean kitchen towel or paper towel to remove surface moisture. This step matters because extra water makes the batter too thin, and a wet batter can lead to a gummy center.
Add the kidney beans, eggs, and baking powder to a blender or food processor.
Blend for 1–2 minutes, stopping to scrape down the sides as needed. You want a mixture that is very smooth and creamy, with no large pieces of bean left. The batter should be thick but pourable, similar to a thick pancake batter or cake batter.
If you see skin fragments or bean chunks, keep blending. A smoother batter gives a softer, more even loaf.
Pour the batter into your prepared loaf pan. Use a spatula to smooth the top into an even layer, then tap the pan lightly on the counter once or twice to release any large air bubbles.
Place the pan in the preheated oven and bake for 30–40 minutes, until the bread is firm in the center and lightly golden around the edges. A toothpick inserted into the center should come out mostly clean.
Oven temperatures vary, so start checking around the 30-minute mark. Overbaking is the most common way to end up with a dry loaf.
Remove the pan from the oven and let the loaf cool in the pan for about 10 minutes. Then carefully lift it out and transfer it to a wire rack to cool completely.
Don’t skip this. The crumb continues to set as it cools, and slicing too early can cause crumbling or a damp, sticky center.
Once fully cool, use a sharp serrated knife to cut even slices. Serve fresh, or toast the slices for a firmer, slightly crisp texture. A thin pat of butter melts nicely on a warm slice, as shown in the photo.
