Onion Challah

Pareve

Onion challah belongs to the savory side of the Jewish bread tradition — the loaf you tear into alongside brisket and roast chicken, the bread that makes a simple egg salad sandwich transcendent. Deeply caramelized onions, cooked low and slow until they surrender every bit of their sweetness, are folded into a rich challah dough. The result is a bread that fills your kitchen with an aroma so compelling that no one can wait for it to cool.

The tradition of onion bread runs deep in Ashkenazi baking. In the shtetl, onions were one of the few flavoring ingredients always available, and Jewish bakers learned to coax extraordinary flavor from this humblest of vegetables. Onion pletzl, onion rolls, onion rye — and at the pinnacle, onion challah, where the sweetness of caramelized onions meets the richness of egg-enriched dough.

The key is taking the time to properly caramelize the onions — a full 30–40 minutes over low heat, stirring occasionally, until they are deep amber and jammy. No shortcuts. The reward is a challah with savory depth that pairs as beautifully with soup as it does with a smear of hummus.

What Makes This Special

• 30-minute caramelized onions — Slowly cooked until deep amber and naturally sweet.
• Savory-sweet balance — The enriched dough provides sweetness while the onions add umami depth.
• Onion topping — Extra caramelized onions pressed onto the surface before baking for visual drama.
• Versatile pairing — Perfect with soups, stews, brisket, or simply toasted with cream cheese.

Step-by-Step Instructions

Step 1: Caramelize the Onions

Heat oil in a large skillet over medium heat. Add sliced onions and salt, stir to coat. Reduce heat to medium-low and cook 30–40 minutes, stirring every 5 minutes, until deeply golden and jammy. Let cool completely. Reserve about ¼ of the onions for topping.

Step 2: Mix the Dough

Combine flour, sugar, salt, yeast, and black pepper. Add eggs, oil, and warm water. Mix and knead 10 minutes until smooth. Fold in the cooled caramelized onions (reserving the topping portion) by flattening the dough, spreading onions, and folding several times until distributed.

Step 3: Bulk Fermentation

Cover and rise 1½–2 hours until doubled.

Step 4: Shape and Proof

Divide in half, braid each into a loaf, place on lined baking sheets. Cover and proof 45–60 minutes. Preheat oven to 175°C / 350°F.

Step 5: Top and Bake

Brush with egg wash. Press reserved caramelized onions onto the surface. Sprinkle with flaky salt. Bake 28–33 minutes until deep golden and internal temperature reaches 87°C / 190°F.

Storage & Make-Ahead

• Room temperature: 2 days wrapped tightly.
• Freezing: Freeze up to 2 months. The onions can make the bread slightly softer upon thawing.
• Make-ahead onions: Caramelize onions up to 3 days ahead and refrigerate.

Troubleshooting

Frequently Asked Questions

Can I use red onions?

Red onions will work but will turn a greyish-purple when caramelized. Yellow or sweet onions produce the best color and flavor for this bread.

Can I add poppy seeds?

Onion and poppy seeds are a classic combination in Jewish baking. Sprinkle poppy seeds over the egg wash along with the onion topping for a beautiful bialy-inspired finish.

Is this challah too savory for Shabbat kiddush?

Not at all. Many families serve both a sweet and a savory challah. The onion challah pairs perfectly with the savory dishes of a Shabbat meal, while a traditional sweet challah accompanies the kiddush wine.

Can I use onion powder instead?

Onion powder will give onion flavor but not the same texture and sweetness of caramelized onions. If pressed for time, sauté diced onions for 15 minutes until softened and golden — not as good as fully caramelized, but still delicious.
