Chicken marinade
For 6 half chicken breasts—roughly the equivalent of 3 whole boneless breasts, usually about 1.25–1.75 lb / 600–800 g—I’d reduce the salt substantially, keep the sumac prominent, and use enough oil and lemon to make a loose paste that coats rather than submerges the chicken.
Suggested marinade
- 2 tbsp extra-virgin olive oil
- 2 tbsp fresh lemon juice (about ½–1 lemon, depending on size)
- 1 tbsp sumac
- 1½ tsp kosher salt
- Or ¾ tsp fine/table salt; table salt is much denser by volume.
- 1½ tsp paprika
- 1 tsp garlic powder
- ½ tsp freshly ground black pepper
This should make approximately ¼ cup / 60 mL of marinade—enough to thoroughly coat six breast halves in a bowl or zip bag.
A comparable sumac-lemon marinade commonly uses roughly equal measures of lemon juice and olive oil, with about 1 tablespoon of sumac for several pounds of chicken; the exact amounts can vary with the cooking method and whether other ingredients are included.[1][2][3]
Changes from your starting point
| Ingredient | Your starting point | Suggested | Why |
|---|---|---|---|
| Salt | 1 tbsp | 1½ tsp kosher / ¾ tsp table salt | One tablespoon would likely be aggressively salty for this amount of lean chicken, particularly if it is table salt |
| Sumac | 1 tbsp | 1 tbsp | Good starting level; it gives the characteristic tangy, berry-like flavour |
| Paprika | 2 tsp | 1½ tsp | Still provides colour and mild warmth without masking the sumac |
| Garlic powder | 2 tsp | 1 tsp | Garlic powder is concentrated and can become dusty or harsh at 2 tsp for this batch |
| Black pepper | 1 tsp | ½ tsp | Lets the lemon and sumac lead; increase to ¾ tsp if you like pepper-forward chicken |
| Lemon juice | Not specified | 2 tbsp | Enough acidity and brightness without leaving breast meat in strong acid for too long |
| Olive oil | Not specified | 2 tbsp | Carries the spices, helps the coating adhere, and supports browning |
Timing and cooking
- Marinate refrigerated for 30 minutes to 2 hours. Breast meat does not benefit much from a very long lemon marinade; after several hours its exterior can become slightly soft or mealy.
- Before grilling, pan-searing, air-frying, or roasting, remove the chicken from the marinade and lightly wipe off excess wet seasoning. This helps prevent the lemon and paprika from scorching.
- Cook until the thickest portion reaches 74°C / 165°F, then rest 5 minutes.
- Finish with a small extra dusting of sumac after cooking. That preserves its tart, fragrant character much better than relying entirely on the marinade.
If you want it more intense
For a more assertive, Middle Eastern-style result, use:
- 3 tbsp olive oil
- 2 tbsp lemon juice
- 1½ tbsp sumac
- 1½ tsp kosher salt
- 2 tsp paprika
- 1 tsp garlic powder
- ½–¾ tsp pepper
That version is particularly good if you will serve it with rice, pita, potatoes, a cucumber-yogurt sauce, or a salad—foods that can carry the extra seasoning. Recipes for sumac chicken often pair lemon juice, olive oil, and a generous amount of sumac in this general range.[2][4][5]
Practical note
If the chicken breasts are very large and thick, butterfly or pound them to a more even thickness before marinating. It gives more even seasoning and makes it much easier to cook them through without drying the thin ends.
