Ingredients
These homemade Croquettes are made with basic ingredients! Here's what you'll need:
- Potatoes - This recipe starts with leftover mashed potatoes. It's a great way to use up extras from a holiday meal!
- Egg - An egg helps to hold the potato mixture together.
- Cheese - I used gruyère cheese, but any cheese that melts well (cheddar, pepper jack, mozzarella, etc.) will work great.
- Bread - You can make your own breadcrumbs from whole wheat bread, or you can use store bought breadcrumbs. Use panko for extra crispy results!
- Olive Oil - The breadcrumbs are mixed with extra virgin olive oil (along with a little salt and pepper), which make helps them become crunchy when baked.
This recipe is naturally vegetarian and nut free. For a gluten free option, simply use gluten free breadcrumbs.
How to Make Croquettes with Leftover Mashed Potatoes

- Prep mashed potatoes. Start by mixing the mashed potatoes with an egg, which will help to hold the croquettes together as they bake.
- Add cheese. Next, cut the cheese into pieces, then form the potatoes around the cheese. The cheese should be totally enclosed when you're done.

Tips for the Best Results
This recipe is super easy to make, but these simple tips will give you the best results:
- Start with cold mashed potatoes. The croquettes will hold together better.
- If the mashed potato mixture sticks to your hands when forming the croquettes, wet your hands first.
- For extra crispy and golden results, fry the croquettes in a few tablespoons of olive oil over medium heat instead of baking.
