Foodgeek is a baking and food website founded in 2014 by Sune Trudslev, sharing tested recipes, practical guidance, and explorations of baking science. Its content focuses especially on sourdough, with recipes spanning everyday loaves, rye and whole-grain breads, sweet enriched doughs, flatbreads, bagels, buns, and breads from around the world. The site also features sourdough discard recipes, including ideas for brownies, waffles, pancakes, and cookies, alongside world food recipes and Danish dishes such as smørrebrød.

Foodgeek organizes its learning resources into guides for beginners, sourdough starters, bulk fermentation, hydration, flour, scoring, troubleshooting, and baking equipment. Articles and side-by-side experiments examine ingredients, techniques, and results to help readers understand why recipes work and how to improve their bakes. The site also provides free baking tools, including calculators and converters for bread recipes, starter feeding, ingredient quantities, yeast, and fermentation planning. Foodgeek offers a newsletter and an optional monthly subscription for an ad-free experience.
