Idaho Potato Herb Soda Bread with Fresh Rosemary and Thyme
Traditional Irish-style soda bread enriched with creamy mashed Idaho potatoes and fragrant fresh herbs. The potatoes create an incredibly tender, moist crumb while rosemary and thyme add earthy, aromatic notes. This rustic loaf bakes up golden and crusty in a Dutch oven, perfect for serving alongside soups, stews, or simply slathered with butter. The potato addition makes this version more substantial and flavorful than classic soda bread, with a texture that stays soft longer. Best enjoyed warm from the oven on the same day it's baked.

Tips
Use a potato ricer rather than masher for the smoothest texture and to prevent gluey potatoes that would make dense bread.
Don't overmix the dough once buttermilk is added - it should look shaggy and rough, similar to biscuit dough.
Test doneness by tapping the bottom of the loaf - it should sound hollow when fully baked through.
Good to Know
Store covered at room temperature for up to 2 days, though best eaten same day.
Can prepare through step 4, refrigerate dry mixture overnight, then add wet ingredients and bake.
Serve warm, sliced thick, with butter or alongside hearty soups and stews.
Common Mistakes
Don't overmix after adding buttermilk to avoid tough bread.
Ensure potatoes are well-drained to prevent soggy dough.
Cut deep X on top to allow proper rising and prevent cracking.
