Chicken Marinade

This low-FODMAP chicken marinade builds bright, savory flavor from garlic-infused oil, fresh lemon, and herbs, so you skip the onion and garlic bulb that most bottled marinades rely on.

Ingredients

Base marinade (enough for about 900 g / 2 lb chicken, roughly 4 servings):

• 1/3 cup (80 ml) garlic-infused olive oil
• 1/4 cup (60 ml) fresh lemon juice (about 2 lemons)
• 1 tsp finely grated lemon zest
• 2 tsp maple syrup (balances the acid; well under the Monash-tested serving)
• 2 tbsp finely sliced scallion (spring onion) GREEN tops only
• 1 tbsp chopped fresh oregano, or 1 tsp dried
• 1 tbsp chopped fresh flat-leaf parsley
• 1 tsp Dijon mustard (read the label for no onion or garlic; use certified gluten-free if needed)
• 3/4 tsp fine salt
• 1/2 tsp freshly cracked black pepper
• 900 g (2 lb) boneless skinless chicken thighs or breasts

Greek variant (add to the base):

• 1 tbsp red wine vinegar
• 1/2 tsp extra dried oregano
• pinch of ground cinnamon (optional, traditional)

Italian variant (add to the base):

• 1 tbsp balsamic vinegar (keep to 1 tbsp; more raises the FODMAP load)
• 1 tsp chopped fresh rosemary
• 1 tsp chopped fresh thyme or basil

Instructions

Mix the marinade

1. In a medium bowl or a large jar, whisk together the garlic-infused oil, lemon juice, lemon zest, maple syrup, and Dijon mustard until glossy and slightly thickened.
2. Stir in the scallion green tops, oregano, parsley, salt, and pepper. Whisk in the vinegar and extra herbs for your chosen variant.
3. Taste on a clean spoon and adjust the salt or lemon. It should read bright and a little salty, since it mellows once it coats the chicken.

Marinate the chicken

1. Pat the chicken dry with paper towels. If using breasts, slice thick ones in half horizontally so they cook evenly.
2. Place the chicken in a zip-top bag or shallow dish and pour the marinade over it. Turn to coat every piece.
3. Refrigerate for at least 30 minutes and up to 12 hours. Because the marinade is acidic, do not go past 24 hours or the surface can turn mushy.

Cook and rest

1. Cook the chicken by your preferred method: grill or pan-sear over medium-high for about 5 to 6 minutes per side, or bake at 425°F (220°C) for 18 to 22 minutes.
2. Cook until the thickest part reaches 165°F (74°C) on an instant-read thermometer. Discard any leftover raw marinade; do not reuse it as a sauce.
3. Rest the chicken 5 minutes before slicing so the juices settle.

Tips & Substitutions

• Scale for meal prep. Triple the base, then portion it into freezer bags with raw chicken and freeze flat. The chicken marinates as it thaws in the fridge.
• Herb swaps. Fresh and dried herbs are both fine here, so use what you have. Roughly 1 teaspoon dried equals 1 tablespoon fresh.
• Sweetener is optional. The maple syrup only rounds out the acid; leave it out or use 1 teaspoon white sugar if you prefer.
• Watch the vinegar. Balsamic is low FODMAP at about 1 tablespoon. For more tang without the cap, reach for red wine vinegar or extra lemon.
• Mustard check. Plain Dijon is usually low FODMAP, but scan the label for onion, garlic, or wheat and pick a clean brand.
• No fresh scallions? Skip them rather than swapping in onion. Green chives also give a mild allium note.

Why This Works

• Garlic-infused oil, not garlic. The fructans that make garlic a trigger are water-soluble, not oil-soluble, so the oil carries the flavor without the FODMAPs.
• Green tops only. The green parts of scallions are low in fructans, while the white bulb is high, so using just the greens keeps the allium flavor gentle.
• Acid does the seasoning. Lemon juice and vinegar tenderize and brighten without the onion or garlic bulb that most bottled marinades lean on.
• Portion-aware add-ins. Maple syrup and balsamic both sit in low FODMAP ranges at the small amounts used here, so a batch stays gentle across several servings. Check the Monash app for current tested serving sizes.

Storage

Store the mixed marinade, before it touches raw chicken, in a sealed jar in the fridge for up to 5 days, or freeze it for up to 3 months. Marinated raw chicken keeps 1 to 2 days refrigerated or up to 3 months frozen; thaw in the fridge before cooking. Cooked marinated chicken lasts 3 to 4 days in the fridge and reheats well. Always discard any marinade that has touched raw chicken.
