onion baked potato on foil
Hasselback onion potato on foil

When we're young we take a lot of things for granted, especially when it comes to food that we don't have to cook ourselves. These potatoes were one of those things I took for granted. My Grandma used to make them and like most things when you're a kid,  I didn't have the appreciation for them back then that I do now. And although I have often, longingly, thought about these Onion Baked Potatoes in Foil over the years, until recently, I've never actually made them myself.

This is such an easy baked potato in foil recipe and a simple way to add some variety and a little pizzazz to your baked potato repertoire. These are great on the grill in the summer, but I make these all year 'round in the oven.

  • 📋 Onion Baked Potatoes in Foil Recipe
  • ⭐ Reviews
  • 🥔 More Potato Recipes

🥘 Ingredients

You only need 3 ingredients for this baked potato with onion recipe:

  • potatoes- you can use any type of potato, yukon gold, red potatoes etc..
  • onion soup mix
  • margarine

I guess these would be considered old skool hasselback potatoes because my Grandma was making these 45 ish years ago. The big difference is that they are not peeled, nor are they cut as thin as hasselback potatoes, meaning way less work! And that's always a good thing because I'm all about less work. Why peel potatoes when you don't have to? Plus, the potatoes peels are full of nutrients! And why make 12 cuts when you only have to make 4 or 5? Am I right?

📖 Variations

  • Baked or Grilled: This baked potatoes in foil recipe is something that my Grandma used to make on the BBQ and I just loved them! However, since it's not currently barbecue season at the time of this posting, I decided to do these potatoes in the oven.  But you can also do these baked potatoes in foil on the grill!
  • Potatoes - I use whatever type I have on hand!
  • Vegan: use vegan margarine to make this vegan. Lipton onion soup mix is vegan.
  • Margarine: you can use butter if you prefer, but I prefer them with margarine, the way my Grandma made them
  • WW Points: Bring the WW points down by using light margarine

There are a lot of baked potato recipes out there and even a few that use butter or margarine with onion soup mix. But I did not see any others that used the exact same method as this. And this method is far superior to the others when it comes to being an easy side dish AND locking in the flavor!

Baked Potatoes in Foil | with onion soup mix

🔪 Instructions

Most of the sliced baked potato with onion recipes instruct the cook to pour the melted onion and butter over the potato. However, you potentially lose a lot of flavor that way. With these Lipton Onion Soup Potatoes, you spread the onion/butter mixture, unmelted, between the slices, then you wrap in foil and bake; it literally locks and bakes in the flavor. It takes a little more time than just pouring melted butter over the potato, but it is well worth it for the rich buttery, onion flavor you get in the end!

⏲️ Baking time

Bake in oven: on 400 degrees F for 40- 45 minutes or until fork easily goes through the potato.

Grill/BBQ method: Follow the above directions, but bake on medium -high grill/BBQ (400 degrees F, with lid down) for 30-40 minutes until fork easily goes through the potato.

💭 Top tip

I always bake these on a large baking sheet when I do them in the oven, as they tend to leak. 

🍽Equipment

You'll need a good utility knife, (affiliate link) a cutting board, a mixing bowl and spoon, as well as a baking sheet and aluminum foil.

👪 Serving Size

This recipe makes 6 servings. However, you can half, double or triple the recipe by clicking on the blue serving number and selecting the number of servings you'd like. The ingredient quantities will automatically adjust. You may need an additional sheet pan.

🔢WW Points

These potatoes are 4 WW points on my plan using light Becel margarine (and 7 with Becel Olive oil margarine), because I get potatoes as a zero points food. Plug the recipe into the recipe builder on your app to see how much they are on your plan.

And these onion baked potatoes are lower fat than indicated in the nutrition label, as some of the margarine does melt off.

🥗What to serve with Onion Baked Potatoes

If I'm making these baked potatoes with onion on the grill, I like to serve them with Marinated Grilled Maple Lemon Pork (shown)and a vegetable. If I'm baking them in the oven, they pair well with Baked Hoisin Chicken!

OR...if you're making these potatoes on the grill, then why not try them with my Weight Watchers friendly BBQ Beer Can Chicken?! (shown)

🌡️Storage

Store these potatoes in airtight container for up to 3 days in the fridge. You can keep the foil on them or take them out. However, if you reheat them in the microwave, be sure to remove the foil! They do not stand up well to freezing.

These sliced potatoes with onions in foil in the oven are an easy recipe, as well as delicious and an economical way to add some excitement to your baked potatoes!

Ingredients

  • 6 medium potatoes
  • 1 -1 ounce - pkg onion soup mix 28 g (approximately)
  • ⅔ cup margarine * I use Becel olive oil margarine
US Customary - Metric

Instructions

  • Preheat oven to 400 degrees F. 
  • Mix margarine (or butter) and onion soup mix together. 
  • Using a sharp knife, make crosswise cuts in each potato about a ½ inch apart, (you want to make about 4 -5 cuts in each potato) stopping about ¼ inch from the bottom of the potato. *Do NOT cut right through. 
  • With a butter knife, add a dab of the margarine (or butter) onion soup mixture between each slice, dividing evenly between all slices in all potatoes.
  • Wrap each potato in aluminum foil (shiny side in) and place on a cookie sheet, as they may leak a little.
  • Bake in oven: for 40- 45 minutes or until fork easily goes through the potato.
    Grill/BBQ method: Follow the above directions, but bake on med-high grill/BBQ (with lid down) for 30-40 minutes until fork easily goes through the potato.

Garnish:

  • You can garnish with sour cream, green onions and bacon bits, if you desire.

    I LOVE potatoes baked this way, and have been making them so for many decades. I started using baby Dutch gold potatoes, or baby Yukon gold potatoes about a year ago, mostly due to the ease of cutting them up, partly due to their delicious flavors, and because I have a major and massive shoulder injury that requires me to find the easiest way to prepare foods from here on out.

      Hi Joyce! Sorry to hear about your massive shoulder injury but that's great you've found a way to work around it and prepare food in the easiest way possible! And wonderful suggestion to use those types of potatoes! Thank you for stopping in to Food Meanderings, taking the time to comment and I hope you'll continue to visit 🙂

    Where is the carbohydrate count for the potatoes? These look great but I am on Keto.

      Hi Marilyn,
      Thanks for bringing this to my attention! There must be something wrong with my calculator (I will contact the people who manage it) but when I search carbohydrates for 1 potato it's 17 g. I hope that helps!

    Here's a hint for cutting the potatoes so that you don't slice all the way through: put them on a spoon then cut. It will prevent you from cutting all the way through! Delicious sounding recipe and will be trying it out! (I have made these with just onions and cheese, alternating btwn slices and a sprinkle of pepper/salt. Yum)

    I'm confident that this potato tastes out of this world. The onion soup mix is really an amazing ingredient. I have used it in brisket.

    My Mum always made these with cut up potatoes. I love how you make them on whole potatoes and sort of Hasselbeck them for intense flavor. The family will love them.
