Air fryer spatchcock chicken with crispy golden skin, juicy meat, creamy mash, and caramelised red wine onion gravy. Come see how easy Sunday dinner can be.
The first time I made air fryer spatchcock chicken, my husband wandered into the kitchen, sniffed the air like a hound, and asked if we were having company. We weren’t. It was just a Tuesday. I’ve made it ever since, mostly because the skin crackles like autumn leaves and I’m a little smug about it.

Why This Air Fryer Spatchcock Chicken Is a Keeper
Here’s the secret: flattening the bird means it cooks evenly. The breast stays juicy while the thighs finish right alongside it. No dry chicken, no pale, flabby skin, and no sad dinner you have to drown in sauce.
The air fryer does the rest. Hot, rushing air turns the skin glassy and crisp, and the whole kitchen smells like roast chicken within minutes. It’s the kind of smell that makes neighbours suddenly remember they haven’t called in a while.
Then there’s the good stuff on the side. A silky, stick-blended mash and a caramelised red wine onion gravy turn a simple chicken into a proper, put-your-feet-up kind of dinner. It feels fancier than it has any right to.

Notes
Gather Your Ingredients
Here’s everything you need, grouped so you can pull it all out at once. I always line mine up on the counter, because I once forgot the red wine until the onions were already done. Lesson learned, and I’m passing it along.
For the Chicken
| Ingredient | Amount | Quick note |
|---|---|---|
| Whole chicken | 1.6kg | Pat it very dry. Dry skin is crisp skin. |
| Olive oil | 2 tsp | Just enough to help the skin brown. |
| Salt and pepper | To season | Be generous. A big bird needs it. |
| Dijon mustard (optional) | 1/4 tsp | Adds a quiet tang. You won’t taste mustard, just depth. |
For the Caramelised Red Wine Onion Gravy
| Ingredient | Amount | Quick note |
|---|---|---|
| Olive oil | 1 tbsp | For the onions. |
| Red onion, finely sliced | 1 medium | Slice thinly so they melt down sweet and jammy. |
| Red wine | 1/4 cup | Use something you’d happily sip. |
| Fresh rosemary, chopped | 1 tbsp | Fresh really matters here. |
| Fresh thyme, chopped | 1 tbsp | Strip the leaves from the stems. |
| Chicken stock | 3/4 cup | Low-sodium helps you control the salt. |
| Dijon mustard | 1/4 tsp | A tiny bit of sharpness. |
| Balsamic vinegar | 1 tsp | Adds a rounded, slightly sweet finish. |
| Salt and pepper | To taste | Taste at the end. |
| Tapioca starch or cornflour (optional) | 1/2 tsp to start | Only if you like a thicker gravy. |
For the Mash
| Ingredient | Amount | Quick note |
|---|---|---|
| Large potatoes, peeled and diced into 1 inch cubes | 4 | Even cubes cook at the same speed. |
| Olive oil or butter | 1 tbsp | Butter for richness, oil for a lighter mash. |
| Salt | To taste | Add it to the water and again at the end. |
A Few Notes Before You Start
If you’re new to spatchcock chicken in air fryer cooking, the size of the bird matters most. A 1.6kg chicken fits most standard baskets once it’s flattened. If you’re not sure, hold it up against your basket before you start.
I’ve tried a lot of ways to make spatchcock chicken air fryer style, and this simple seasoning wins every time. Every other recipe I tried years ago left the wings scorched. Tucking them behind the breast fixes that completely.
How to Make Air Fryer Spatchcock Chicken Step by Step
Spatchcock the Chicken
Remove any giblets, then lay the chicken breast-side down on a board. Run a finger along the back to find the backbone and the soft outer edge of the ribcage. That’s your guide.
Using strong kitchen scissors or a sharp knife, start at the tail end and cut along one side of the backbone up to the neck. Repeat on the other side. Lift out the whole backbone and set it aside. My grandmother always said it makes the best stock.
Turn the chicken breast-side up and open it like a book. Press down firmly on the breastbone until the whole bird lies flat. You might hear a satisfying little crack, which is exactly what you want.
Tuck the wings behind the breast so they don’t overcook. It looks a bit like the chicken is relaxing with its hands behind its head, and honestly, same.
Season and Air Fry
Preheat your air fryer to 350F / 176C. While it warms up, mix the olive oil and dijon together if you’re using it. Rub it all over the skin, getting into every nook, then season generously with salt and pepper.
Place the chicken in the air fryer skin side up. If you’d like easier clean up, line the base with parchment first. Just make sure it’s weighed down by the chicken so it doesn’t fly up into the heating element.
Cook for 50 to 55 minutes, until cooked through and crisp. Around the halfway mark you’ll hear the sizzle pick up and smell the skin turning deep gold. Resist the urge to keep opening the basket. I’ve done it, and it doesn’t help.
For peace of mind, check that the thickest part of the thigh reaches 165F / 74C, the safe minimum internal temperature for poultry according to the USDA.
Make the Mash
While the chicken cooks, add the potatoes to a large pan of boiling salted water. Bring it back to the boil, then reduce to a medium simmer and cook for 15 minutes, until soft and fork tender.
Drain well and pat the potatoes dry with kitchen paper. Dry potatoes make fluffier, creamier mash, and nobody wants a watery bowl of sadness.
Add the olive oil or butter and blitz with a stick blender for the creamiest texture you’ve ever had. Season with salt to taste. A potato masher or fork works if you don’t own a stick blender, but this trick is honestly life changing for your mash.
Simmer the Gravy
Add the olive oil to a non-stick pan over low heat. Add the sliced onions and cook gently for 8 to 10 minutes, until caramelised and golden. Don’t rush this by cranking up the heat. I’ve burned them at least twice, so learn from me.
Add the red wine, herbs, stock, dijon, balsamic, salt, and pepper. Simmer on low for about 15 minutes, until the gravy has reduced by a third to a half. It’ll turn glossy and smell like a cozy pub in winter.
Want it thicker? Stir 1/2 tsp tapioca starch into 2 tbsp of water in a mug, then stir it into the gravy. Cook for about two minutes until it thickens to your liking. I prefer a loose jus, so I skip the thickener, but it’s your dinner.
Shred and Serve
Shred the chicken and pile it onto warm plates next to a big scoop of mash. Spoon the gravy over everything and garnish the chicken with fresh parsley. Then sit down, because you’ve earned it.
Tips, Swaps, and Variations
Tips for Crispy, Juicy Chicken
Dry the chicken thoroughly before oiling it. If you have time, leave it uncovered in the fridge for an hour or two first. The skin dries out beautifully and comes out even crisper.
Let the chicken rest for about 10 minutes before shredding. The juices settle back in, and the meat stays tender instead of leaking all over your board.
Easy Swaps
No red wine? Use extra chicken stock plus a splash more balsamic. The gravy will be a touch lighter, but still lovely. Out of fresh herbs? Use about a third of the amount in dried, though fresh really does taste better here.
Not a fan of mash? Roast potatoes, steamed greens, or buttery carrots all sit nicely beside this chicken.
Fun Variations
Rub the skin with a little smoked paprika and garlic powder for a smokier flavour. Or scatter lemon zest over the chicken just before serving for a bright, fresh finish.

When Things Go Sideways
The skin isn’t crisp. The chicken was probably still damp, or the basket was overcrowded. Pat it dry next time, and give it a few extra minutes if you need to.
The breast is dry. It likely cooked a little too long. Start checking the temperature at the 45 minute mark, and pull it out the moment the thigh hits 165F / 74C.
The wings are scorched. They weren’t tucked in tightly enough. Tuck them firmly behind the breast, and they’ll shelter nicely.
The gravy is too salty. Add a splash of water or unsalted stock and a tiny bit more balsamic. Next time, use low-sodium stock and taste before seasoning.
The mash is gluey. Over-blending can do it. Pulse in short bursts and stop as soon as it’s smooth.
Storing and Reheating Leftovers
| Item | Fridge | Freezer |
|---|---|---|
| Shredded chicken | 3 to 4 days, airtight | Up to 2 months |
| Gravy | 3 to 4 days, airtight | Up to 2 months |
| Mash | 3 to 4 days, airtight | Up to 1 month |
Cool everything quickly before storing, in line with the USDA’s leftovers guidance. Don’t leave it sitting out for hours while you watch one more episode.
Reheating Advice
Warm the chicken in the air fryer at 320F / 160C for 5 to 7 minutes. It’ll crisp up again without drying out. Gently reheat the gravy in a small pan, adding a splash of stock if it’s thickened up in the fridge.
Mash reheats best in a saucepan over low heat with a spoonful of butter or a splash of milk, stirred often. Microwave works too, just stir halfway through.
No-Waste Ideas for Leftovers
- Stir leftover chicken into a creamy chicken a la king for a second dinner.
- Pile cold shredded chicken into sandwiches with a smear of leftover gravy.
- Simmer the saved backbone with an onion and herbs for a quick homemade stock.
- Fold leftover mash into golden potato cakes and pan fry them.
Frequently Asked Questions
Why spatchcock a chicken in the air fryer?
Flattening the bird lets it cook evenly and fit in the basket. You get juicier meat and far crispier skin than you would with a whole, rounded chicken.
What size chicken works for spatchcock chicken in air fryer cooking?
This recipe uses a 1.6kg chicken, which fits most standard baskets once flattened. If your air fryer is small, check the fit before you start, since a larger bird may not sit flat.
How do I know the chicken is cooked through?
Use a meat thermometer in the thickest part of the thigh. It should read 165F / 74C, and the juices should run clear.
Can I make the gravy ahead of time?
Yes. Make it up to 3 days ahead and store it in the fridge, then warm it gently in a pan. Add a splash of stock if it’s thickened.
Do I have to use the dijon?
No, it’s optional. It adds a subtle tang to the skin and gravy, but the recipe is still delicious without it.
