Roast dinner is always a winner in our home. An easy way to feed your family a hearty meal, use up any vegetables from the bottom of the fridge and best of all there are usually leftovers for the next day. This Ninja Foodi gammon joint is super simple to prepare, tastes delicious and is perfect for feeding a crowd!
I do love to make a Ninja Foodi roast beef joint sometimes too, or a slow cooker whole chicken, so there is lots of choice for everyone. This recipe is great for those days when I decide on the spur of the moment to make a roast dinner and don’t necessarily want to spend a fortune on it.
The pressure cooker setting on the Ninja Foodi is a fantastic way to cook dinner in a hurry, ideal for those Sundays when you end up catering to guests unexpectedly, as seems to happen a lot on weekends.
When this gammon joint is ready I will let it rest, under some tin foil, for around 30 minutes. While it rests I make Ninja Foodi roast potatoes (check out my 5 tricks for crispy roast potatoes too!), air fryer sage and onion stuffing, air fryer pigs in blankets, yorkshire puddings and make a lovely glaze to pour over the top too, alongside gravy. It makes for the tastiest roast dinner, with a LOT less time standing over a hot oven! I love to serve this with a brown sugar BBQ sauce too with mashed potatoes.
If you’re serving up a tasty roast dinner then this Ninja Foodi apple crumble is perfect for dessert.

Ingredients for Ninja Foodi gammon joint recipe:
Gammon joint of choice – I used a 1.1KG sized (approx) smoked gammon joint (boneless ham).
10 black peppercorns
2 garlic cloves
1 onion
2 stalks of celery
3 bay leaves
Water
Method for cooking gammon in the Ninja Foodi:
Optional first step: Soak your gammon joint to remove some of the saltiness.
Place the gammon joint in your slow cooker.
Chop the onion into 4 wedges.
Chop the celery stalks in half.
Add the peppercorns, garlic cloves (crush a little), onion wedges, celery stalks and bay leaves.
Cover the gammon joint with water. Keep an eye on the pressure cooker maximum line in your Ninja Foodi pot.
Pressure cook for 12 minutes per 500g of gammon, (25 minutes for my recipe) then use the quick release method to release the steam to prevent further cooking.
I used the temperature probe for my gammon joint, and set it to stop cooking when the joint hit 68C (155F), which is the ideal safe internal temperature of a gammon joint. This was 25 minutes and I pressure cooked my gammon straight from the fridge.
Rest the gammon before slicing.

Can you make diet coke gammon in the Ninja Foodi?
Many manufacturers of pressure cookers will tell you not to use carbonated drinks, so I just make this in my slow cooker instead, rather than risk it malfunctioning and spraying my kitchen with diet coke! I love to make slow cooker balsamic gammon too!
Want to use something other than water for your gammon joint?
Adding some orange juice in works well, particularly if you’re using a small joint. Once the gammon is cooked you could use some of this juice, boil it on the hob, and thicken it up for a lovely glaze. This gives your gammon a lovely look, and is nice if you want to display a feast as your guests sit to dinner!
These easy ham glazes are a great place to start with creating your own ‘secret sauce’ for gammon.
Want to add a glaze to your gammon joint?
I’d suggest glazing it and finishing it off using the air crisp setting. Some of my favourite glazes are marmalade, maple syrup with apple juice and mustard or simple honey and mustard.
Remove your gammon, brush the thick glaze of choice on, score the top, then air fry for 5-7 minutes until the glaze has cooked well.
Rest before slicing and serving.
Can you use this Ninja Foodi roast gammon for sandwiches?
Absolutely! It is delicious and works very well in sandwiches. I like to whip up some sandwiches, using air fryer bread rolls or soft white rolls, and then keep these in the freezer for lunches when I’m low on time or fancy something a little special.
Do you need to seal the gammon first?
I don’t do anything to the gammon before cooking besides remove all of the plastic packaging and give a wash over as required.
What vegetables work well with gammon?
For a roast dinner we really feel like anything goes. Roast potatoes are a given, and then I love to serve with Cavolo Nero, air fryer baby carrots, air fryer carrot and parsnips, red cabbage, air fryer honey glazed parsnips and peas.
Is this Ninja Foodi gammon joint sliceable?
Yes, as long as you don’t overcook it. The main thing you want to do when slow cooking or pressure cooking meat is to rest it after cooking for 30 minutes or so wrapped in tin foil. This keeps the joint nice and warm, and keeps the lovely juices in too.
This meat slices up great, as you can see, and the slices are perfect for 1-2 per dinner portion with plenty of leftovers for tasty gammon sandwiches, or even just a simple gammon, egg and chips dinner one night!
