Recipe ingredients
All ingredients for this Instant Pot ham and scalloped potatoes recipe are shown in the pic below, and special notes are included in this bulleted list to assist you.
- Chicken broth. Use store-bought or homemade, or vegetable broth, Smoked Chicken Stock, or Smoked Turkey Stock.
- Potatoes. You can use any type of potatoes - red, Yukon Gold, or russet potatoes - peeled or with the skin on. Cut into even ½-inch cubes for perfect cooking. I used red potatoes, but you can use any type, even baby potatoes. You can also add some sweet potatoes.
- Ham. Use leftover Double Smoked Ham or Baked Ham. You can also use Air Fryer Bacon (or any cooked bacon), Smoked Sausage (or any cooked sausage), canned ham, or even leftover chicken or turkey.
- Milk. I used whole milk, but you can make a richer sauce with half-and-half or heavy cream, or a lighter sauce with 2% or 1% milk. You can even use evaporated milk.
- Sour cream. Use plain yogurt or plain Greek yogurt instead.
- Cheese: I used white cheddar cheese, but you can use sharp cheddar cheese, Gouda, Monterey Jack, or whatever kind you have - even mozzarella cheese would work.
- Flour - Use cornstarch instead of all-purpose flour to thicken the sauce.
- Seasonings - I used my favorite seasonings, but feel free to add your favorites to make it your own.

How to make Instant Pot scalloped potatoes and ham
- Preheat your oven to 375 degrees F and grease a 9 x 13-inch casserole dish with cooking spray.
- Cut potatoes into ½-inch cubes and place them in the Instant Pot. Add chopped onion on top and pour in chicken broth.
- Secure the lid and pressure cook on high pressure for 2 minutes. Do a quick release when the timer is up.
- Use a slotted spoon to move potatoes to the prepared baking dish.
- Press 'Cancel' on your Instant Pot and then 'Saute'. Pour milk into the remaining broth. Add flour, salt, black pepper, garlic powder, onion powder, and paprika. Whisk until smooth and thickened.
- Mix in sour cream and 1-½ cups of shredded cheese. Stir until melted.
- Add the diced ham and stir to combine.
- Pour the mixture over the potatoes in the casserole dish and stir to combine.
- Top with remaining cheese and bake, uncovered, for 15 minutes at 375 degrees F.
- Broil for 2-3 minutes until golden brown and bubbly, garnish with fresh parsley if desired, and serve immediately. Enjoy!
Top tips
- Cut the potatoes into ½-inch cubes and no bigger. I use a mandolin to make this job easier.
- After pressure cooking, use the quick-release method to prevent the potatoes from becoming too soft or mushy.
- When making the sauce, whisk continuously to prevent lumps. Add a splash of milk if it gets too thick.
- Assemble early and bake when ready.
What to serve with cheesy scalloped potatoes
These are my favorite dishes to serve with these au gratin potatoes:
- Vegetable Sides: Air Fryer Green Beans, Air Fryer Brussels Sprouts with Bacon, and Easy Air Fryer Carrots.
- Fresh and Light: Greek Cucumber Salad, Broccoli Crunch Salad, and Carrot Salad.
- Bread & Rolls: Homemade Air Buns, No Knead Sourdough Bread, and Homemade Biscuits without Milk.
Variations
- Vegetarian: Skip the ham and add a mix of sautéed mushrooms, bell peppers, and spinach, and use vegetable broth instead of chicken broth.
- Spicy: Add diced jalapeños, red pepper flakes, or cayenne pepper.
- Crunchy topping: Mix breadcrumbs with melted butter and sprinkle over top before baking.
Equipment
- I used a large 8-quart Instant Pot to make this recipe, but even a smaller pressure cooker will work.
- A 9 x 13-inch casserole dish.
Storage and reheating
Refrigerator: Store leftovers in an airtight container in the refrigerator for 3-4 days.
Freezer: Cover and store in the freezer for up to 2 months.
Reheating: If frozen, thaw in the fridge overnight, then reheat in the oven at 350 degrees F, covered, for 25-30 minutes until heated.
