If you have ever sat at a Jewish deli counter and been handed a basket of rye bread so fragrant with onion and caraway that you ate three slices before your pastrami arrived, you know this bread. Onion rye is the unsung hero of the Ashkenazi bread tradition — sturdy enough for a stacked sandwich, flavorful enough to eat on its own, and perfuming your entire home as it bakes.
This recipe builds on the classic Jewish rye formula with generous additions of caramelized onions folded into the dough and more scattered on top. The rye flour gives it that characteristic tang and density, the caraway seeds add their warm, anise-like note, and the onions bring sweetness that rounds everything out.
Shape it as a round boule or an oblong batard — both are traditional. Slash the top deeply before baking for that classic bakery look. The crust should crackle when you press it, and the interior should be moist, tight-crumbed, and deeply flavorful.
What Makes This Special
- Dual onion technique — Caramelized onions in the dough and on top for maximum flavor.
- Authentic rye tang — A 30% rye flour blend for real deli-style flavor without being too dense.
- Caraway seeds — The signature flavor of Jewish rye, toasted for extra depth.
- Sandwich-perfect crumb — Tight enough to hold pastrami, moist enough to eat plain.

Ingredients
| Ingredient | Grams | Volume | Baker’s % |
|---|---|---|---|
| Bread flour | 350 g | 2¾ cups | 70% |
| Dark rye flour | 150 g | 1¼ cups | 30% |
| Granulated sugar | 15 g | 1 tbsp | 3% |
| Fine sea salt | 10 g | 1¾ tsp | 2% |
| Instant yeast | 7 g | 2¼ tsp | 1.4% |
| Caraway seeds | 8 g | 1 tbsp | 1.6% |
| Warm water | 300 g | 1¼ cups | 60% |
| Vegetable oil | 15 g | 1 tbsp | 3% |
| Caramelized onions (cooled) | 200 g | 1 cup | 40% |
Step-by-Step Instructions
Step 1: Caramelize Onions
Slice 3 large yellow onions thinly. Cook in 2 tbsp oil over medium-low heat for 30–40 minutes until deep amber. Season with ½ tsp salt. Cool completely. Reserve ¼ for topping.
Step 2: Mix and Knead
Combine flours, sugar, salt, yeast, and caraway seeds. Add water and oil, mix to a shaggy dough. Knead 8–10 minutes — rye dough stays slightly sticky. Fold in ¾ of the cooled caramelized onions.
Step 3: Bulk Fermentation
Cover and rise 1½–2 hours until doubled.
Step 4: Shape
Shape into a tight round boule or oblong batard. Place on a parchment-lined baking sheet or in a banneton. Cover and proof 45–60 minutes.
Step 5: Score and Bake
Preheat oven to 220°C / 425°F with a pan of water on the bottom rack for steam. Score the top of the loaf with a sharp blade. Press reserved caramelized onions onto the surface. Bake 35–40 minutes until the crust is dark and the internal temperature reaches 93°C / 200°F. Cool completely on a wire rack before slicing.
Storage & Make-Ahead
- Room temperature: 3–4 days wrapped. Rye bread keeps well.
- Freezing: Slice before freezing for easy single-serve use. Up to 3 months.
- Best use: Day-two rye is ideal for sandwiches; the crumb tightens slightly.
Troubleshooting
| Problem | Cause | Solution |
|---|---|---|
| Dough extremely sticky | Normal for rye | Use wet hands; rye gluten is weaker than wheat; dough improves with rest |
| Dense loaf | Too much rye flour | Maintain the 70/30 wheat/rye ratio; do not exceed 40% rye |
| Bland flavor | Caraway omitted or not toasted | Toast caraway seeds in a dry pan 2 minutes before adding; they carry the flavor |
Frequently Asked Questions
Can I use light rye instead of dark?
Yes, but dark rye gives more flavor and color. Light rye produces a milder, lighter loaf. Both work.
Is this the same as corn rye?
No. Corn rye uses a cornmeal-dusted crust. This recipe focuses on onion as the star flavor. You can dust the bottom with cornmeal if you like.
What is the best sandwich for this bread?
Classic pastrami on rye with mustard is hard to beat. It also excels with corned beef, egg salad, or a simple smear of cream cheese with lox.
Can I make this with a sourdough starter?
Absolutely. Replace the yeast with 200 g active rye sourdough starter and reduce the water by 100 g. Allow a longer bulk ferment of 4–6 hours.
