Preheat the oven to 350 degrees F. Coat an 8 1/2 x 4 1/2-inch loaf pan with nonstick cooking spray and line the bottom with parchment paper.
Blend the cottage cheese, eggs, and olive oil until completely smooth and creamy.
Whisk the flour, baking powder, baking soda, salt, and 1 tablespoon of everything bagel seasoning in a large bowl.
Fold the cottage cheese mixture into the dry ingredients just until no dry flour remains. The batter will be thick, so spread it evenly in the prepared pan.
Sprinkle the sesame seeds, poppy seeds, and remaining everything bagel seasoning over the top. Press the toppings lightly into the batter.
Bake for 45 to 52 minutes, until the loaf is deeply golden and a tester inserted in the center comes out clean. If the top browns too quickly, loosely cover the pan with foil during the final 10 minutes.
Cool in the pan for 15 minutes, then transfer the bread to a wire rack and cool completely before serving.
