Spelt French dip sandwich rolls are soft, lightly nutty rolls filled with thin-sliced roast beef and melted Swiss, served with a warm onion beef jus for dipping. The rolls bake from scratch, and most of the 148 minutes is hands-off rising time.
The crumb stays tender and the crust stays thin. That suits a dipped sandwich, because the roll soaks up jus without falling apart. Spelt adds a mild, slightly sweet flavor that works well with roast beef.
You can bake the rolls a day ahead. The jus and beef keep for 3 to 4 days in the fridge. On the night, you warm the beef, fill the rolls and melt the cheese.
Slice the beef as thin as you can. Thin slices stay tender in the hot jus and pile neatly on the roll.
Why You’ll Love This Recipe
- Spelt rolls stay soft inside with a thin, crisp crust
- Rolls bake a day ahead, so dinner comes together fast
- The jus uses pantry stock, onion and Worcestershire
- Deli roast beef or sliced leftover roast both work

Ingredient Notes
- White spelt flour: White (light) spelt gives a softer crumb than whole grain. If you only have whole grain spelt, use it for all 500 g and add 2 tbsp extra milk.
- Roast beef: Ask the deli counter to slice it paper-thin, or chill a cooked roast and slice it with a sharp knife. Leftover roast works well.
- Swiss cheese: Provolone and Gruyere both melt cleanly. Choose slices about 3 mm thick so they melt in 4 minutes.
- Beef stock: Use low-sodium stock so the jus can reduce without turning too salty. A good boxed stock works fine.
- Instant yeast: If you only have active dry yeast, use the same amount and stir it into the warm milk for 5 minutes before mixing.

Baked Spelt French Dip Sandwich Rolls with Beef Jus
Description
Baked spelt rolls with a thin crust and a tender crumb, filled with roast beef and melted Swiss. The onion jus simmers while the dough proofs, so the work overlaps.
Ingredients
Spelt rolls
Onion beef jus
Filling
Instructions
Make the spelt rolls
- Whisk both spelt flours, the yeast and the salt in a 4-quart / 3.8 L mixing bowl. Stir in the warm milk, honey and soft butter until a shaggy dough forms. Knead on a lightly floured surface for 8 minutes, until smooth and slightly tacky. Add flour by the tablespoon only if it sticks to your hands.
- Put the dough in a bowl greased with the olive oil, cover, and let it rise at room temperature for 60 minutes, until doubled. Stop there. Spelt gluten is delicate, and dough that rises past double slumps and bakes flat.
- Line a 33 x 46 cm / 13 x 18 inch baking sheet with parchment. Divide the dough into 6 pieces of about 145 g. Flatten each piece, fold it into thirds, and roll it into a 15 cm / 6 inch oval with the seam underneath. Space the rolls 5 cm / 2 inches apart, cover loosely, and proof for 30 minutes, until puffy.
Simmer the onion beef jus
- While the rolls proof, melt 15 g butter in a 3-quart / 2.8 L saucepan over medium heat. Cook the onion for 8 minutes, until soft and golden. Stir in the garlic for 1 minute. Add the stock, Worcestershire, thyme, bay leaf and pepper, then simmer gently for 15 minutes, until slightly reduced. Keep it on low heat.
Bake and assemble the French dip sandwich rolls
- Heat the oven to 200 C / 390 F during the last 15 minutes of proofing. Brush the rolls with the egg beaten with 1 tbsp water. Bake for 18 minutes, until deep golden and the bottoms sound hollow when tapped. Cool on a rack for 10 minutes.
- Split each roll lengthwise with a serrated knife, leaving one long edge attached. Spread the cut sides with mustard. Remove the bay leaf, bring the jus to a gentle simmer, and add the beef. Warm it for 1 minute, then lift it out with tongs, divide it among the rolls and top each with a slice of cheese.
- Set the filled rolls on the baking sheet and return them to the oven for 4 minutes, until the cheese melts. Ladle the jus into 6 small bowls, about 100 ml each, and serve right away.
