Bone Marrow Steak Subs: FAQ
1. Q: Can’t find bone marrow bones? What’s the best substitute?
→ A: Use beef tallow, duck fat, or truffle aioli for similar richness. For meat lovers, foie gras pâté adds luxury.
2. Q: Is the 12-hour bone soak mandatory?
→ A: CRITICAL STEP! Soaking draws out blood/impurities for pure, buttery marrow flavor. Skip it → risk gritty texture & off-tastes.
3. Q: Can I prep components ahead?
→ A: YES!
- Soak bones 24h ahead
- Sauté veggies 1 day prior (store airtight)
- Cook steak 2h early → slice AFTER resting, store in herb butter
4. Q: Why rest steak before slicing?
→ A: RESTING = JUICY RIBBONS! Cutting too soon releases precious juices. Wait 10 mins → flavor locks into every slice.
5. Q: How do I prevent soggy bread?
→ A: DOUBLE TOAST!
→ Brush rolls with herb butter
→ Toast cut-side down in steak pan drippings BEFORE assembling
6. Q: Cheese isn’t melting evenly !
→ A: PROVOLONE PRO-TIP:
→ Cover subs loosely with foil during broiling → cheese melts without burning
→ Use ROOM TEMP cheese slices
7. Q: Can I make this vegetarian?
→ A: TRY THIS PLANT-BASED BOMB:
- Replace steak with portobello mushrooms + eggplant (sear like steak)
- Swap bone marrow with miso-tahini spread
- Use veg-friendly cheese

→ A: FLAVOR GOLD!
