Copycat Subway Sweet Onion Chicken Teriyaki Wrap at Home
The Subway sweet onion chicken teriyaki is a cult order: juicy glazed chicken, crunchy fresh vegetables, and that sweet onion sauce that ties the whole thing together. Recreating it at home is easier than you would think, and the homemade version has real advantages — you control the sugar in the sauce, the chicken is freshly cooked rather than held warm, and each wrap costs under £2 instead of the £6-plus you would pay in store. This copycat subway chicken teriyaki wrap delivers the full experience in about 25 minutes: caramelised teriyaki chicken strips, a homemade sweet onion sauce, and loads of crunchy veg in a toasted wholemeal wrap.
The honest framing, consistent across this whole series: this is a homemade recipe inspired by Subway’s sweet onion chicken teriyaki. It is not affiliated with or endorsed by Subway, and it is not their actual proprietary recipe — their sauces are made to closely guarded formulas I have no access to. What follows is my own from-scratch sweet onion sauce and teriyaki glaze, built from supermarket ingredients and tested until the wrap tastes like the craving it is answering.
- A homemade take on Subway’s sweet onion chicken teriyaki, with from-scratch teriyaki glaze and sweet onion sauce.
- Around 450 calories and 40g of protein per wrap (estimated), for under £2 in ingredients.
- Ready in 25 minutes; the chicken cooks in one pan while you chop the vegetables.
- Both sauces use supermarket staples — no specialty bottles required.
- Not affiliated with Subway — an inspired-by home recipe, not the official product.
Breaking Down the Copycat Subway Chicken Teriyaki Wrap
A great copycat starts by identifying what actually defines the original. Here it is three things: the chicken, the sweet onion sauce, and the fresh crunch. The chicken in the shop version is pre-cooked and reheated; at home you get to cook it fresh, which is an immediate upgrade. Thin strips of chicken breast, seared hard in a hot pan and then glazed with a quick teriyaki sauce, give you caramelised edges and juicy centres that the original can only dream of.
The teriyaki glaze is a simple reduction: soy sauce, a little honey, garlic, ginger and rice vinegar, simmered until syrupy. It takes five minutes and tastes leagues better than any bottle, because you control the sweetness — the shop glaze leans very sweet, and most home cooks prefer it dialled back a notch. The glaze should coat the chicken thickly and shine; if it is watery, it has not reduced enough.
The sweet onion sauce is the signature element. The homemade version blends light mayonnaise with finely grated onion, a touch of mustard, rice vinegar and a little sweetener, rested for at least 15 minutes so the raw onion mellows into sweetness. It will not be identical to the squeezy bottle — nothing homemade ever is — but it hits the same sweet-savoury notes and, frankly, tastes fresher. The vegetables are the easy part: shredded lettuce, sliced peppers, red onion and cucumber for crunch, all chopped fresh.

How to Make the Sweet Onion Chicken Teriyaki Wrap
Make the sweet onion sauce first so it has time to mellow while you cook. Then it is one pan for the chicken and a chopping board for the veg — weeknight-simple.
- Make the sweet onion sauce: whisk the light mayonnaise with the grated onion, Dijon, rice vinegar (1 tablespoon), sweetener and a pinch of salt. Cover and refrigerate for at least 15 minutes.
- Make the teriyaki glaze: simmer the soy sauce, honey, grated ginger, crushed garlic and remaining rice vinegar in a small pan for 4 to 5 minutes until slightly syrupy. Set aside.
- Slice the chicken breasts into thin strips, about 1 cm thick, cutting against the grain. Season with salt and pepper.
- Heat a large frying pan over high heat with a light spray of oil. Sear the chicken strips in a single layer for 2 to 3 minutes per side until golden and cooked through. Work in two batches if needed — crowding steams the chicken instead of searing it.
- Pour the teriyaki glaze over the chicken in the pan and toss for 1 to 2 minutes until every strip is lacquered and the sauce clings. Sprinkle with sesame seeds.
- Warm the wraps in a dry pan for 30 seconds per side until pliable and lightly toasted in spots.
- Spread a generous tablespoon of sweet onion sauce down the centre of each wrap. Pile on the shredded lettuce, sliced peppers, cucumber and red onion.
- Top with the hot glazed chicken, drizzle over a little more sweet onion sauce, and roll tightly, tucking in the sides as you go. Rest seam-side down for a minute to seal, then halve and serve.
Rolling Without Tearing
Do not overfill — it is the number one cause of wrap blowouts. Warm wraps are pliable wraps; a cold wrap cracks. If your wraps are small, serve the filling as two open wraps or in bowls over rice instead of forcing a roll that will split.
Estimated Nutrition per Wrap
Approximate estimates for one of two wraps, based on typical own-brand labels. A planning guide, not laboratory analysis.
| Nutrient | Per Wrap (estimate) |
|---|---|
| Calories | ~450 kcal |
| Protein | ~40 g |
| Carbohydrates | ~52 g |
| Fat | ~9 g |
| Fibre | ~7 g |
| Salt | ~2.0 g |
Forty grams of protein in a wrap you actually look forward to eating is the headline. The fat stays low because the sauces are mayonnaise-light rather than oil-heavy, and the wholemeal wrap plus a mountain of vegetables keeps the fibre respectable. Watch the salt if that is a concern for you — soy sauce is the main contributor, and a reduced-salt soy sauce swaps in with no change to the method.
Storage and Reheating
Assembled wraps are best eaten fresh, but the components are excellent for meal prep. The glazed chicken keeps for 3 days in the fridge and reheats in a hot pan or microwave until steaming; the sweet onion sauce keeps for 5 days refrigerated in a sealed jar; chopped vegetables keep for 2 days. Assemble fresh each time — a pre-rolled wrap goes soggy within hours as the vegetables release water. The teriyaki glaze alone keeps for a week in the fridge and is superb on salmon, tofu or stir-fried vegetables, so consider doubling it deliberately.
Easy Variations
Swap the chicken for king prawns — sear for 2 minutes per side and glaze the same way. A vegetarian version with smoked tofu or Quorn-style pieces works well; glaze them exactly like the chicken. Add pickled red onions for sharpness, or sliced mango for a sweet-heat contrast that works surprisingly well with teriyaki. For a lower-carb version, serve the whole thing as a bowl over shredded lettuce and extra cucumber instead of in a wrap, saving around 180 calories. Spice lovers can add sriracha to the sweet onion sauce or sliced fresh chilli to the vegetables. And if wholemeal wraps are not your thing, a toasted ciabatta-style roll turns it into a sandwich that still honours the original brief.
Copycat Subway Chicken Teriyaki Wrap FAQs
Is this the actual Subway sweet onion chicken teriyaki recipe?
No. This is a homemade recipe inspired by Subway’s sweet onion chicken teriyaki. It is not affiliated with or endorsed by Subway, and their actual proprietary sauce formulas are not public.
Can I make the sweet onion sauce ahead?
Yes — it actually improves with resting. Make it up to 5 days ahead and refrigerate in a sealed jar. The grated onion mellows into sweetness as it sits.
My teriyaki glaze is too thin. What went wrong?
It needs longer simmering. Keep it at a gentle bubble until it coats the back of a spoon — it thickens further as it cools. If you are in a hurry, a quarter teaspoon of cornflour mixed with cold water will tighten it instantly.
Can I use chicken thighs instead of breast?
Yes. Thigh strips are juicier and more forgiving of high heat; sear for 3 to 4 minutes per side. Each wrap gains roughly 60 calories.
How do I keep the wrap from going soggy in a lunchbox?
Pack the components separately and assemble fresh, or spread the sauce between the chicken and the vegetables rather than directly on the wrap. A layer of lettuce against the wrap acts as a moisture barrier.
