ABOUT THIS RECIPEA balance of sweet, tangy and creamy
Sweet potato gives this breakfast bowl substance and a soft, almost creamy center. In the oven, the cubes caramelize at the edges; cumin makes their sweetness a little earthier and spicier. Cut the pieces to about the same size, around two centimeters, so they cook evenly. Spread them out on the baking sheet: if they’re piled on top of one another, they’ll steam rather than develop browned edges. A hot oven and plenty of space matter more here than extra oil.
Tahini, made from sesame seeds, turns into a smooth sauce with lemon juice and cold water. Tahini can be firm or quite runny in the jar, so add the water a little at a time. At first, the mixture may seem thicker; keep stirring, then add a little more water until the sauce runs off a spoon. Taste before adding salt, since tahini varies by brand. If the sauce is too sharp, a little extra water will help; more lemon makes it fresher.
The pickled red onion adds tang and a little bite alongside the soft potato and egg. Slicing it thinly helps: the slices take on some flavor in a short time while staying crisp. Rice vinegar or white wine vinegar can replace regular vinegar. Feel free to let the onion sit longer if you want to prepare it ahead; keep it covered in the fridge and use a clean fork to take portions from the jar.
Cook the egg just long enough to keep the yolk soft, but don’t leave it in hot water after cooking: it will continue to cook. An extra minute gives you a firmer but still creamy yolk. If you don’t use cilantro, you can use parsley instead; it adds a milder, green note. The herbs aren’t just for decoration: their fresh flavor lifts the roasted, creamy elements.
Serve the bowls as soon as the potato comes out of the oven, so the sauce and egg don’t cool down. The components are also easy to make ahead: store the roasted potato, sauce and pickled onion separately in the fridge, and heat the potato all the way through before serving. It’s best to serve the egg freshly cooked. An extra lemon wedge lets everyone make their bowl brighter to taste; bread is delicious for mopping up the last of the tahini sauce.
