Preheat your oven to 400 degrees.
Prepare a rimmed baking sheet with tinfoil. Set aside.
Get out and measure all of your ingredients.
Using a sharp knife, make slices across the potato about ⅛ to ¼ inch apart, making sure to cut ¾ of the way down the potato, not all the way through. The slices should stay connected at the bottom of the potato as best you can.
When all of the potatoes are cut, place them cut side up on your prepared sheet.
Coat potatoes with olive oil and place a piece butter or garlic butter in between every other slice or so.
Sprinkle with a few shakes of salt and pepper.
Bake for 60-75 minutes, depending on the size of your potatoes. Use a toothpick to confirm potatoes are cooked throughout.
In the meantime, grab your skillet and add your chopped bacon to it. Cook bacon until almost crispy. Drain on paper towel and set aside. On occasion, I'll leave some bacon fat in my skillet and fry some onion inside it, maybe some mushrooms too. You can shove sliced swiss cheese in between the potato slices and serve mushrooms and onions on top. Oh so good too! The possibilities are truly endless with these delicious hasselback baked potatoes!
Remove potatoes from your oven and turn your oven up to broil.
Stuff cheese and bacon or ham between each of the potato slices.
Place roughly ¼ of your bacon into each potato and as much cheese as you like.
Return to oven and cook for 5-10 minutes or until cheese is totally melted.
Serve with sour cream and some green onions! Enjoy every bite!
