Leftover mashed potatoes are good in the fridge for 3-5 days if they are stored properly in a sealed container.
Reheat mashed potatoes on the stovetop over low heat or in the microwave, adding a splash of milk, cream, or butter to bring back their creamy texture. If you really have to and are crunched on time, you can also use the microwave. Make sure to cook them on a lower power to ensure they don’t scorch and of course you will need to add a little liquid as well.
Yes, if you don’t feel like using up the leftovers right away you can freeze the mashed potatoes. Make sure you cool them to room temperature then place in a freezer safe container or freezer bag. Make sure to label them and then freeze for another meal.
Yes, instant mashed potatoes can work in many leftover recipes, though the texture may be slightly different than homemade.
Not always. Many of the recipes below will call for cold mashed potatoes, especially when forming patties or even soups that will warm as they cook.
Tips and Tricks for Using Leftover Mashed Potatoes
Here are a few of my tips and tricks when using leftover mashed potatoes in recipes.
- Start with cold mashed potatoes for best results – Cold mashed potatoes are easier to shape into patties, balls, or doughs. They hold together better and won’t fall apart when cooking.
- Add a binder when needed – If your mashed potatoes feel too soft, mix in an egg, shredded cheese, or a little flour to help hold everything together—especially for pancakes, croquettes, or waffles.
- Don’t skip seasoning – Leftovers can taste a little flat after sitting in the fridge. Taste and adjust with salt, pepper, garlic powder, or fresh herbs before cooking.
- Use a scoop for even portions – A cookie scoop keeps things uniform when making potato cakes or bites so everything cooks evenly (and looks prettier too!).
- Crisp them up for better texture – Whether you’re pan-frying or baking, aim for golden, crispy edges. A hot skillet with a little oil or butter makes all the difference.
- Add mix-ins to level them up – Think chopped bacon, green onions, shredded cheese, or even leftover veggies to give your mashed potatoes new life and flavor.
- Thin them out for soups – Too thick? Add broth or milk and turn mashed potatoes into a creamy soup base in minutes.
- Reheat low and slow – Avoid blasting them in the microwave. Low heat with a splash of milk or cream keeps them smooth and creamy instead of dry or gluey.
- Use them as a shortcut ingredient – Leftover mashed potatoes can replace part of the dough or filling in recipes like shepherd’s pie, casseroles, or even savory breads.
- Don’t let them go to waste – If you’re not ready to use them right away, freeze in small portions so you can grab exactly what you need later.

The slow cooker lemon chicken orzo soup is chocked full of veggies, chicken, and flavor and makes enough to feed an army! I also love that it doesn’t really require a lot of ingredients. For instance, you only need 2 boneless skinless chicken breast. From the looks of the soup you would think I used a few pounds of chicken. A few veggies, nothing over the top, plus one cup of orzo pasta and you’ve got yourself a heart soup! You can prep your veggies the night before and place them in a container or a baggie to dump into the slow cooker the next morning or spend a few extra minutes in the morning prepping dinner.

























































































































































And in case you’ve never used/bought Meyer Lemons. I have a great storing tip for you. Store lemons away from foods with strong odors. If you refrigerate them they will last for up to 20 days! This works for all lemons but you definitely want to keep your Meyer Lemons away from the stinky foods. They are super fragrant and you don’t want to alter their fragrance.
