What to serve with best homemade mashed potatoes recipe?

Potatoes are one of those things that can be served with countless main dishes because they’re so versatile. It’s rare for a dinner to come along that I can’t serve potatoes with. However, some dishes are better than others. Below are some of my favorite dinners to serve with mashed potatoes.


Milk substitute – Almond milk, coconut milk, oat milk, and similar options can be used in place of regular milk. You can also use half and half, heavy cream or evaporated milk.

Add other types of cheeses – You don’t have to stick with just cheddar. Consider adding other cheeses such as cream cheese, ricotta, mozzarella, fiesta blend, feta, gouda, etc.

Add vegetables – For a heartier dish, you can add vegetables such as peas, carrots, corn to the dish once it’s finished cooking. Please note that the veggies will need to be cooked before being added.

Add meat – Add protein to the dish or make it even heartier by mixing in cooked meat like shredded chicken or shredded beef.

Make it vegetarian – Use vegetable broth instead of chicken broth.

Make it spicy– Add some chopped jalapenos (fresh or pickled). You can also add some diced green chilies or red pepper flakes.

Add bacon– Bacon bits or fried and crumbled bacon always makes for a delicious topping addition.

Other topping options – Sour cream, various shredded cheeses, cooked vegetables, butter slices, crumbled bacon, shredded chicken, shredded beef, fresh herbs like parsley, green onions, chives, cilantro.

Tips and Techniques for easy creamy mashed potatoes

Use low salt ingredients- This is especially with regards butter and broth. Make sure they are unsalted and low sodium to prevent this side dish from becoming too salty.

Broth alternative– Stock can be used instead of broth. Don’t replace it with water because it doesn’t add any flavor to the overall dish.

Use full fat ingredients- This is with regards to milk and cheeses, sour cream. That’s because the higher the fat content, the more creamier and richer the end results.

Use hot milk- Because it also allows everything to blend together more smoothly.

Adjust amount of garlic and cheeses- Add more or less, based on your preference.

Sour cream substitute– Full fat Greek yogurt works very well.

What are the best potatoes for mashed potatoes? Yukon gold are the best, hands down!

Should I cut potatoes before boiling for mashed potatoes? Yes, because it allows them to cook faster. Make sure they are all around the same size.


Refrigerate – Store in an airtight container for 2-3 days.

Freeze – Freeze in an airtight container, without toppings, for up to 2 months.

Reheat – Reheat in the microwave.

Make ahead instructions– Make these a day in advance and heat them on the warm setting on the day you are serving.
