What to serve with mashed potatoes?

Potatoes are one of those things that can be served with countless 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.

  • Salisbury Steak
  • Chicken Fried Steak
  • Seasoned Pork Chops
  • Fried Chicken
  • Roasted Turkey
  • Oven Baked Ham


Milk substitute – Almond milk, coconut milk, oat milk, and similar options can be used in place of the milk.

Use other cheeses – You don’t have to stick with cheddar. Try other cheese options such as mozzarella, fiesta blend cheese, Gouda, etc.

Add vegetables – For a heartier dish, you can add vegetables such as peas, corn, green beans, etc. to the dish once it’s finished cooking. The veggies will need to be cooked/heated before adding.

Add meat – Add protein to the dish or make it even heartier by adding cooked meat. I like adding baked or fried chicken pieces to the top like a KFC bowl.

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.

Add more toppings – Sour cream, other cheeses, vegetables, butter, and other similar ingredients go well on the top of these potatoes. Treat them like a baked potato.


Refrigerate – Store in an airtight container for up to 5 days.

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

Reheat – Reheat using the microwave or small pot over the stove.
