Preheat your oven to 425°F and line a baking sheet with parchment paper. Have a small bowl of water nearby for wetting your hands—this will prevent the sticky dough from sticking to your fingers when shaping. I find that keeping your hands consistently moist throughout the shaping process makes it much easier to create a smooth, uniform bagel.

In a medium bowl, whisk together the lupini flour, baking powder, salt, and garlic powder. Add the yogurt to the dry mixture and stir with a spatula or wooden spoon until a thick, shaggy dough forms. The dough will be quite dense and slightly sticky—this is normal for a high-protein bagel. Mix until all the dry ingredients are fully incorporated and no flour pockets remain.

Wet your hands with water and gather the dough from Step 2 into a ball. Form it into a bagel shape by creating a hole in the center using your thumbs and gently stretching the dough into a ring approximately 3-4 inches in diameter. The dough should be roughly 1/2 inch thick. I recommend working quickly but gently—the dough is more forgiving than traditional bagel dough, so don't worry if it's not perfectly even.

Place the shaped bagel from Step 3 onto your prepared baking sheet. Generously sprinkle the everything bagel seasoning over the top and sides of the bagel, then press it firmly into the dough with your wet fingers to ensure the seasoning adheres during baking. This firm pressing is crucial—it keeps the seasonings from sliding off as the bagel rises and bakes.

Bake the seasoned bagel for 20-25 minutes, until the top is golden brown and the bagel feels firm when lightly pressed. The bagel should have risen slightly and developed a light crust. Since lupini flour is different from wheat flour, it won't brown as deeply, so look for a light golden color rather than a dark brown.

Remove the bagel from the oven and let it cool on the baking sheet for 10-15 minutes before slicing. This cooling period allows the crumb structure to set and makes slicing cleaner. Once cooled, slice horizontally and enjoy your high-protein bagel with your favorite toppings.
