Ingredients
To make onion mashed potatoes, you will need these ingredients:
Potatoes- I used Maris piper potatoes. Others that are great for this recipe are russet potatoes, King Edwards,
Onions - Brown, yellow, or white onions work fine. Dice the onions into tiny pieces so they are cooked tender and mash beautifully with the potatoes.
Milk- This will make it creamy and also thin out the mash so it's not too thick. Adjust quantity accordingly.
Butter- Salted or unsalted works fine.
Salt
Black pepper
Onion granules
You will also need a large pot to use on the stove and a large bowl for serving.
How To Cook Mashed Potatoes With Onions
Once you have the ingredients, it’s time to make mashed potatoes with onions!
Follow these easy steps:
Peel the potatoes. Cut them into chunks of about 1-2 inches and rinse them under cold water.
Chop the onion into small pieces.
Add the washed potatoes and chopped onions to a large pot. Cover with enough water so that all the potatoes and onions are submerged by at least 1 inch then add salt.
Boil until the vegetables are soft. Use a fork to check the doneness.
Drain the potatoes and onions.
Immediately add butter, milk, onion granules, and black pepper to the potatoes.
Mash till smooth using a potato masher, mixer, or fork.
Serve hot as a side dish or even on their own!
Remember, you can always serve these onion mash potatoes with extra salt, pepper, or butter if you wish. Some fresh herbs like parsley would also be a nice touch. You could even make loaded mashed potato bowls KFC-style with some corn and popcorn chicken. Yum!
Serving Suggestion
Pair it with chicken, turkey, sandwiches, or wraps. Here are some suggestions for chicken, steak, lamb, and vegetables you can serve with:
Pan fried steak, Instant pot steak
Baked boneless chicken breast, air fryer frozen chicken drumsticks, Air fryer thin chicken breast
Air fryer broccolini, Boiled carrots
Storage and Reheating
Once the mash is completely cool, it’s time to store the leftovers. Grab any airtight container like Tupperware, or a Ziploc, put the remaining potatoes inside of it, label, and store it in the fridge where it will keep well for up to three days.
You might be wondering if you can freeze mashed potatoes, and the answer is yes. Put them in a freezer-friendly Ziplock bag or container, label them, and store them for up to 6 months. Just make sure you thaw them in the fridge before reheating them.
To reheat, one of the quickest methods is in the microwave. Heat them for 2 minutes, then remove and stir before putting them in the microwave for an additional 1-2 minutes. Ensure they are hot again before you eat them.
You can also reheat it in a pot over medium heat. Try adding some additional milk or butter if you try this method to help the consistency get smooth and creamy again.
Tips
