Vietnamese Banh Mi Spice Rub
A fragrant, aromatic dry spice blend inspired by Vietnamese banh mi seasoning. This rub balances warm spices, bright garlic, and subtle sweetness to season grilled meats, vegetables, or marinated proteins for banh mi sandwiches and other Vietnamese dishes. Toast the spices to unlock their essential oils for maximum flavor.
Steps
Before you start
- Measure all spices before toasting
- Use a dry skillet with no oil
- Toast over medium heat to avoid burning
Toast whole spices
- Place white peppercorns, coriander seeds, and star anise pieces in a small dry skillet (8–10 inch / 20–25 cm) over medium heat.
- Toast for 2–3 minutes, stirring frequently with a wooden spoon, until the spices become fragrant and the coriander seeds turn golden brown.
- Listen and watch for them to darken slightly—the aroma will peak when they're ready.
- Pour onto a plate to cool for 1 minute.

Ready when: Spices are fragrant and coriander seeds are golden brown
Tip: Do not walk away—toasted spices burn quickly. The smell will change from pleasant to acrid if overcooked.
Grind toasted spices
- Transfer the cooled toasted spices to a spice grinder or mortar and pestle.
- Grind until the mixture reaches a fine powder with just a few small pieces remaining (not paste-like).
- This should take about 30–45 seconds in a grinder.
- Pour into a small bowl.

Ready when: Mixture is a fine, fragrant powder
Tip: Don't over-grind into a paste; a few small pieces add texture. If using a mortar and pestle, this will take 2–3 minutes of gentle grinding.
Mix in remaining ingredients
- Add garlic powder, white sugar, kosher salt, and the ground spice mixture to the small bowl.
- Stir with a spoon for about 30 seconds until all ingredients are evenly distributed and there are no clumps.
- The rub should be uniform in color and texture, with no visible pockets of salt or sugar.

Ready when: All ingredients evenly combined with no visible clumps
Tip: If the rub feels damp or forms clumps, it's absorbing humidity. Let it sit uncovered for 10 minutes, then stir again before storing.
Store or use immediately
- Transfer the spice rub to a clean, dry glass jar with a tight-fitting lid.
- Label it with the date.
- Use immediately to season grilled pork for banh mi, coat chicken or fish before cooking, or mix with oil to create a marinade.
- For banh mi pork, use about 2–3 tablespoons per pound of meat.

Ready when: Rub is sealed in an airtight jar
Tip: Store away from heat and light. The rub will stay fresh for up to 3 months, though the aroma will gradually fade.
Good to know
Tips
- Toast the whole spices just before grinding to preserve their aromatic oils—pre-ground spices lose potency quickly.
- To use as a wet marinade, mix 3 tablespoons of rub with 3 tablespoons fish sauce, 2 tablespoons oil, and 1 tablespoon rice vinegar for pork banh mi.
- The sugar in this rub helps create a flavorful crust when meats are seared or grilled. It may char slightly, which adds depth.
- If you don't have a spice grinder, a clean coffee grinder works perfectly, or use a mortar and pestle (which will take longer but gives you control over texture).
Make ahead
The spice rub can be made up to 3 months ahead and stored in an airtight container at room temperature. Prepare it in larger batches and keep on hand for quick banh mi meals, grilled meats, or seafood.
Storage & reheating
Room temperature: Up to 3 months in an airtight glass jar away from heat and light. The flavor will peak in the first month. No refrigeration or freezing needed.
Substitutions
- white peppercorns → Black peppercorns. Use the same amount. Black pepper is slightly more peppery and will darken the rub slightly, but works well.
- coriander seeds → Ground coriander (already ground). If you only have ground coriander, use 1½ tablespoons (9 g) and skip the toasting step. Mix it directly with other ingredients.
- star anise pods → ½ teaspoon fennel seeds. Fennel is closely related and milder. Toast it with the other spices. The anise note will be subtler.
- white sugar → Light brown sugar. Use the same amount. Brown sugar adds a slight molasses note and may give the rub a slightly darker color.
