The Best onion soup potatoes recipe

I have been making this onion soup potatoes recipe for years, and it’s always a crowd-pleaser. My kids love helping me in the kitchen, and this recipe is one of their favorites.

They get to mashing the potatoes with a fork, which they think is the best part of the job. The smell of onions sautéing in butter is amazing, and it fills the entire house with a savory aroma.

My husband loves how easy it is to make this recipe, and he always requests it for dinner. I like that it’s a hearty meal that can be made in under an hour.

The best part of this recipe is that you can customize it to your taste by adding different herbs or spices. My family loves it when I add some grated cheddar cheese on top, which melts perfectly into the potatoes.

This recipe has been passed down through generations in my family, and we’ve tweaked it to our liking over the years. We’ve made it for holidays, weeknights, and even potlucks.

It’s a versatile recipe that never fails to impress.
