Sourdough Discard Hoagie Rolls

I was craving a super soft sub bun like the ones at Jimmy Johns, and guess what? This recipe nails it! Plus, they’re a fun and simple bake! This recipe uses a cup of sourdough discard for a real tangy flavor, combined with commercial yeast for that perfect rise.

These hoagie rolls (or sub buns—whatever you want to call them) will totally elevate your sandwich situation. Do you love recreating deli sandwiches at home? This feels like a natural step when you make your own killer bread. Maybe it’s just a sourdough-lover thing, but it really takes sandwiches to the next level!

Here’s a little secret: adding corn grits on top is totally optional but adds a wonderful bit of texture and a slight crunch that contrasts so nicely with the soft rolls. It’s my favorite extra touch!

Ingredients

You probably have most of these pantry staples already!

• Yeast – Since this recipe uses sourdough discard, we add dry active yeast to make sure the rolls get that fluffy rise we all want.
• Sugar – Sugar is a superstar here! It helps soften the rolls, boost the rise, extend their shelf life, encourage a beautiful brown crust, and adds a nice round sweetness to balance everything.
• Water – Just plain warm water to hydrate everything and activate the yeast.
• Sourdough discard – We’re adding a cup here, which is a fantastic way to use up that discard. It gives these rolls fantastic flavor. Keep in mind, the older your discard is, the tangier it’ll taste—so give it a quick sniff before using!
• Oil – I usually go with vegetable oil, but any neutral oil you have will work perfectly.
• Flour – I love mixing half all-purpose and half bread flour for a perfect chewy-soft balance. But if you want to use just one, that’s totally fine too!
• Salt – Don’t forget this one! I recently learned the hard way what happens when you skip or mismeasure salt. It really makes a difference.
• Corn grits – Totally optional, but a sprinkle on top before baking adds that little crunchy surprise we all love on soft rolls.

How to Make Homemade Hoagie Rolls

These rolls come together so easily! I always get a thrill when I use commercial yeast with sourdough discard—the rise is quick and reliable, plus that classic sourdough flavor is still there.

1. Mix the dough and set it aside to rise.
2. Divide and shape your dough pieces.
3. Let the shaped dough rise a second time.
4. Brush with water and sprinkle on the corn meal.
5. Score the tops lightly.
6. Bake to golden perfection.
7. Let them cool down.
8. Dig in and enjoy!

Shaping Buns

Use whatever shaping technique you’re comfortable with, especially if you already make bread loaves—you can shape these just like that.

Sizing

Want big sub buns? Divide the dough into 8 equal pieces, around 133 grams each. Prefer smaller buns, maybe for the kids or mini sandwiches like at Jimmy Johns? Go for 16 portions. I usually make a mix of big and small rolls, so there’s something for everyone.

What Kind of Sandwiches to Make with These

Honestly, the sky’s the limit! Having these fresh rolls ready means your sandwich game is instantly on point.

Still need some inspiration? Here are a few favorites to get those creative juices flowing:

• Cold cuts. Hit up your favorite deli and go crazy with meats, cheeses, and all the toppings you love!
• Grinders – I tested the viral TikTok grinder sandwich on these rolls, and wow—they did not disappoint! (You’ll spot these in a few pictures below too. I might have overloaded my camera roll with them.) From cold to hot subs, these rolls handle it all beautifully.
• French dip sandwiches – Toast the rolls so they hold their structure when dunked in all that delicious au jus.
• Philly cheesesteaks – A classic for a reason. These rolls are perfect to scoop up all that melty goodness.

I swear, I went a little overboard with photos of this sandwich—I just can’t help it, it’s that good!

Storage Tips

To keep your hoagie rolls fresh, store them in an airtight container or resealable plastic bag at room temperature. They’ll stay soft and tasty for up to 5 days. If you want to keep them longer, just pop the rolls in the freezer once cooled. Wrap them well in plastic wrap and place in a freezer bag. When you’re ready to eat, thaw at room temperature and warm in the oven for a few minutes to bring back that fresh-baked vibe.

Make-Ahead Tips

These rolls are perfect for making ahead! You can prepare the dough and shape the rolls, then refrigerate them overnight during the second rise. Just make sure to cover them well. The next day, let them come to room temperature for about 30 minutes before baking. This slow rise adds extra flavor and fits nicely into busy schedules.

Variations

• Flour swaps: Try swapping half the bread flour with whole wheat flour for a heartier roll with a touch of nuttiness.
• Herb twist: Mix some dried herbs like oregano or thyme into the dough for a subtle Italian flair.
• Seed topping: Instead of corn grits, sprinkle sesame or poppy seeds on top before baking for a little extra crunch and flavor.
• Cheesy rolls: Add some shredded parmesan or cheddar on top right after brushing with water for a melty, golden crust.

Serving Suggestions

These hoagie rolls are incredibly versatile! Here are some tasty ideas to enjoy them:

• Fill with your favorite deli meats, cheese, lettuce, tomato, and a swipe of mayo for a classic cold sub.
• Make a hot sandwich like a Philly cheesesteak or meatball sub—these rolls hold up wonderfully.
• Turn them into sloppy joes or pulled pork sandwiches for a family-friendly dinner everyone will love.
• Use them as slider buns for mini sandwiches at your next gathering or party.

Recipe FAQs

• Can I use all sourdough starter instead of discard? For this recipe, it’s best to use discard as it’s less active and won’t cause the dough to rise unevenly. Using a very active starter might affect the texture and rise.
• What if I don’t have bread flour? You can use all all-purpose flour, though the rolls may be slightly less chewy. Mixing with bread flour creates a nice balance, but all-purpose works just fine.
• How do I know when the rolls are done baking? The rolls should be golden brown on top and sound hollow when tapped. For a precise check, use a thermometer—the internal temp should be 200 to 210°F.
• Can I skip the corn grits topping? Yes, they taste great without it! The corn grits just add a little crunch and that classic deli roll feel, but it’s totally optional.
• How do I reshape if the dough gets too sticky? Just dust your hands and work surface lightly with flour. Try not to add too much flour, or rolls might get dense. Sticky dough is normal and helps keep the rolls soft.
