Begin by preheating your oven to 350°F and preparing your 9 × 5-inch loaf pan by greasing it thoroughly and lining both the bottom and sides with parchment paper. This step guarantees your loaf will release easily after baking and makes cleanup considerably simpler.
In a large bowl, break 4 extra-large eggs and beat them together with a fork until the yolks and whites are fully combined.
Once the eggs are ready, add all the remaining ingredients: 3 tablespoons of olive oil, 1 cup of finely chopped dried cranberries, 1 teaspoon of salt, ¾ cup of mixed seeds, 1½ cups of chopped pistachios, ⅔ cup of chopped walnuts, and ½ cup of chopped skin-on whole almonds.
Mix all the ingredients together thoroughly until they're evenly distributed throughout the egg and oil base. The mixture should come together into a chunky, cohesive batter with no dry pockets remaining.
Pour the entire mixture into your prepared loaf pan, spreading it evenly with a spatula to confirm uniform baking.
Bake the loaf for 45–50 minutes, watching for it to turn golden brown and feel firm in the center when gently pressed.
Once baked through, remove the loaf from the oven and allow it to cool completely on a wire rack before slicing. This cooling period is indispensable, as it allows the loaf to set properly and makes for cleaner, more presentable slices.
