Ingredients

- 1 tsp dry oregano
- 1 tsp dry thyme
- 1.5 lb (700 g) small tri-color potatoes (red, white, blue colors)
- 1/4 (60 g) red bell pepper
- 1/4 (60 g) orange or yellow bell pepper
- 2 (200 g) zucchini, medium
- 2 tbsp garlic-infused oil
- 1/2 tsp salt
Instructions
- In a small bowl, mix the mayo, oregano, and thyme until well combined.
- Slice the chicken breasts horizontally into thinner cutlets for even cooking.
- Coat the chicken evenly with the herb mayo mixture. Transfer to a resealable plastic bag or container and refrigerate for at least 2 hours, preferably overnight.
- Bring a large pot of water to a boil. Add the potatoes and cook for 5 minutes. Drain well and allow them to dry for a few minutes.
- Cut the bell peppers into large wedges and the zucchini into thick slices or rounds.
- In a large bowl, toss the potatoes, bell peppers, and zucchini with the garlic-infused oil and salt until evenly coated.
- Preheat the grill or BBQ to medium-high heat (about 400–450°F / 200–230°C). Clean and lightly oil the grates.
- Place the chicken and vegetables on the grill. Cook the chicken for 4–6 minutes per side, or until it is no longer pink inside in the thickest parts (the internal temperature must be minimum 165°F (74°C)).
- Grill the vegetables, turning occasionally, until tender and lightly charred, about 10–15 minutes. The potatoes should be golden and crisp on the outside.
- Transfer everything to a serving platter and let the chicken rest for 3–5 minutes before serving.
- Serve immediately and enjoy!
Low FODMAP Serving Size
This dish is designed for comfort: chicken and potatoes are FODMAP-free; zucchini and bell peppers are low FODMAP in typical serving sizes, which is 1/4 of the amount required by the recipe.
Use only a mayo without onion or garlic: Always check labels on condiments and oils for hidden high-FODMAP ingredients.
Don’t forget about FODMAP stacking and watch out for other foods containing fructose (bell peppers) or fructant (zucchini) in the same meal.
Substitutions
If you need to adjust for allergies, availability, or taste, here are easy swaps that keep the flavor (and the FODMAPs) in check.
- Boneless, skinless chicken thighs can replace breasts; grill slightly longer and cook to 165°F (74°C).
- Use dairy-free or egg-free mayo (without onion/garlic) to accommodate allergies and keep it low FODMAP.
- Swap oregano/thyme for smoked paprika and lemon zest for a brighter flavor.
- If garlic-infused oil is unavailable, use plain zoil; you can add lemon zest and a pinch of asafoetida/hing (gluten-free) for aroma.
- High-smoke-point oils (avocado or canola) can stand in for olive oil on hot grills.
- Any color bell pepper works; choose firm peppers for better grill marks.
- Use small Yukon Gold or fingerling potatoes if tri-color aren’t available; sweet potato works in low-FODMAP portions (about 1/2 cup cooked).
- Swap potatoes for carrots – just boil the carrots for 6-7 min.
- Swap zucchini for grilled brussels sprouts (check out our recipe) – they both contain fructant so do not mix them.
- Add scallion greens or fresh chives for oniony notes without FODMAPs.
- For extra heat, use red pepper flakes or a mild chili powder (both low FODMAP in modest amounts).
What to Serve With It
- Simple green salad with lemon, olive oil, and chive tops (green parts only)
- Quinoa or rice pilaf with parsley and toasted almonds (if tolerated)
- Grilled corn cut into small segments (mind portions to keep it low FODMAP)
What Else You Should Know
Slice chicken breasts horizontally for thinner cutlets: this speeds cooking and keeps them juicy. Parboil potatoes for 5 minutes, then let them dry; dry surfaces crisp better on the grill.
Oil hot, clean grates right before grilling to prevent sticking. Use an instant-read thermometer and pull chicken at 165°F (74°C).
For FODMAP comfort, ensure the garlic-infused oil is well strained and the mayo contains no onion or garlic. Rest grilled chicken 3–5 minutes so juices redistribute and each bite stays tender.
Conclusion
From herby mayo–coated chicken cutlets to char-marked potatoes, peppers, and zucchini, this recipe brings effortless summer flavor with low-FODMAP peace of mind. A short parboil guarantees crisp, tender potatoes; garlic-infused oil delivers aroma without triggers; and the grill seals in juiciness fast.
It’s make-ahead friendly, beginner-approved, and ideal for Labor Day or any easy dinner. Rest the chicken, watch for 165°F doneness, and serve hot off the grates.
Whether you’re feeding family or a crowd, every bite tastes bright, balanced, and satisfying—proof that simple technique and smart ingredients turn weeknight staples into cookout stars. Fire up, dig in, and enjoy
