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; they are a delicious side dish!
You only need 3 simple ingredients for this baked potato with onion recipe:
- potatoes- you can use any type of potato, yukon gold, red potatoes etc..
- onion soup mix - I use Lipton
- margarine - I use Becel
*see recipe card for quantities
I guess these oven-baked potatoes would be considered old-skool hasselback potatoes because my Grandma was making these 45-ish years ago. And it's really the easy way to make them.
The big difference is that these foil-wrapped potatoes 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 potato skins are full of nutrients! And why make 12 cuts when you only have to make 4 or 5? Am I right?
- 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 (russet potatoes etc)-you can use any kind of potato. However, I like to use larger potatoes, as they are easier to slice and fill. You could also substitute sweet potatoes.
- 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 lighter 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!
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 the potatoes; 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!
⏲️ Cooking time
Bake in oven: on 400 degrees F/204 degrees C (on middle oven rack in a regular oven) for 40- 45 minutes or until fork easily goes through the potato. Baking time will vary, depending on the size of potato you are using. If you are using a convection oven, you'll need to adjust temperature to 375 degrees F/190 degrees C.
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.
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.

These potatoes are 5 WW points using light Becel margarine, as potatoes are no longer 0 (zero) points on the plan.
And these onion baked potatoes are lower fat than indicated in the nutrition label, as some of the margarine does melt off.

Store these potatoes in an 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.
