Need a recipe for leftover ham? This is the one you for you. Kind of like potato dauphinoise, but made even better with pieces of ham and caramelised onions. These Scalloped Potatoes are comfort food heaven!
A luxury side dish for Christmas or Thanksgiving!
Or if you don’t want to serve up these scalloped potatoes as a side dish, make it the main event with a few little additions.
I’m using chunks of leftover baked ham, buttery fried onions and 3 different cheeses.
It’s carblicious, ultra cream and cheesy, and probably a million calories (I’ll work it out and include in the recipe card), but who cares when it tastes this good?
We start by frying up slices of onion in a pan (1) with butter, garlic, salt, pepper and a little garlic salt. Five or six minutes is enough to get sweetly softened light brown onion, but you can cook for 8-10 minutes more than that if you love really caramelized onions. Turn off the heat.
Make the sauce by melting butter in a saucepan, then stirring in flour to form a roux (2). Heat for a minute to cook out the flour, then while stirring with a whisk, slowly add the milk, a good splash at a time (3). When all of the milk has been added, stir in the cream and cheddar cheese (4).
Arrange a layer of potatoes (no need to pre-cook them) in a greased baking dish (5), and top with half the onions, half the ham and a good pinch of salt and pepper (6). Spoon over half the sauce (7).
Repeat the layers once more (7, 8, 9, 10), then top with cheddar, Gruyere and red Leicester (11). Cover with foil and bake in the oven for 75-90 minutes, until the potatoes are tender throughout (12).
Remove the foil and cook for a further 15-20 minutes until the cheese is browned and bubbly. Top with fresh thyme before serving.
What’s the difference between potato dauphinoise and scalloped potatoes?
- Potato dauphinoise is a French dish of thinly sliced potatoes (not usually pre-cooked), baked with cream and/or milk, a hint of garlic (more for the aroma than the flavour) and sometimes a little nutmeg. Cheese may or may not be added.
- Scalloped potatoes – Scalloped potatoes are often argued to be cooked with cream, garlic and onion, but without cheese. Many recipes do call for the addition of cheese though (including mine!). The potatoes are usually sliced a little thicker than with potato dauphinoise.
Can I cook the potatoes first?
You can cook the sliced potatoes in milk or stock for 10-12 minutes first if you wish. This will speed up the overall cooking process, meaning the dish will only need around 30 minutes in the oven (uncovered).
I prefer not to pre-cook the potatoes as I find draining the potatoes too messy, and I’m too impatient to wait for the potatoes too be cool enough, so I can handle them when I layer them up in the pan.
Suggestions for swaps:
If you want to change up this recipe, you could swap out the ham for bacon or even pepperoni or chorizo (salty meats work best).
You can also replace some or all of the potato with sweet potato or slices of butternut squash (like this squash and potato gratin)

- 6 tbsp plain (all-purpose) flour
- 2 1/3 cups (560ml) full fat milk
- 3/4 cup (180ml) double (heavy) heavy cream
- 1 1/2 packed cups (150g) grated mature cheddar cheese
- 1/2 packed cup (50g) grated Gruyere cheese
- 1/2 packed cup (50g) grated Red Leicester cheese
- 1 tbsp chopped fresh thyme
- Preheat oven to 180C/350F. Grease a large casserole dish.
- Heat the butter in a frying pan (skillet) on a medium-high heat. Add the onion, garlic, ¼ tsp salt, ¼ tsp black pepper and ¼ tsp garlic salt. Fry for 5-6 minutes, stirring often until the onions soften. Turn off the heat.
- Now make the cheese sauce. Melt the butter in a saucepan over a medium-high heat. Add the flour and stir with a whisk. Cook for 1 minute, stirring constantly.
- Add the milk, a splash at a time, whilst stirring with the whisk until incorporated, and no lumps remain.
- Add the cream and three quarters of the cheddar cheese. Stir until the cheese melts.
- Arrange half of the potatoes in the bottom of the casserole dish. Top with half the onion mixture and half of the cubed ham. Sprinkle over ¼ tsp salt and ¼ tsp black pepper.
- Pour over half the sauce.
- Repeat the layers with the potato, onion, ham, salt, pepper and the remaining sauce.
- Sprinkle the remaining cheddar cheese, the Gruyere and red Leicester over the top.
- Cover the dish with foil and place in the oven for 75-90 minutes - until the potatoes are tender (you can check by pushing a knife through them, They should cut through potatoes easily).
- Remove the foil and cook for a further 15-20 minutes until the cheese is golden and bubbly.
- Remove from the oven and allow to rest for 5 minutes, then serve topped with a sprinkling of fresh thyme.
*Which potatoes to use?I find the best types of potato are floury potatoes - as the starch in them helps to create a thicker sauce. Maris Piper, King Edwards, Rooster, Russets, Yukon golds and Desirée are all good options.
Can I make it ahead and reheat later?Yes, you can cook the dish as per the instructions, then cool, cover and refrigerate for up to two days. Reheat, covered in foil for 30-35 minutes at 180C/350F until piping hot throughout.
Can I freeze it?I find the potatoes, although still tasting great, can have a slightly grainy texture when frozen and reheated, so I don't recommend it.
If you do have leftovers and want to freeze them, then cook the dish, cool, cover and freeze. Defrost in the refrigerator overnight, then reheat, covered in foil for 30-35 minutes at 180C/350F until piping hot throughout. Nutritional Information is per serving.
