Grilled Potato Casserole


"This is a great potato casserole for the grill. Clean up can't get any easier than just tossing the foil! These can also be baked in a 350 degree oven if space on the grill is at a premium. Don't be tempted to skip the celery seed, it's what makes these unique."

  • Prep

  • Cook

  • Ready In

  1. Preheat an outdoor grill for medium-high heat.
  2. Melt the butter in a saucepan over medium-low heat. Whisk in the flour, salt, seasoned pepper, and celery seed; cook and stir for 1 minute. Gradually whisk the milk into the flour mixture, and bring to a simmer over medium heat. Cook and stir until the mixture is thick and bubbly, 5 to 10 minutes.
  3. Stir in the potatoes, onion, and green bell pepper. Pour the potato mixture onto a large sheet of heavy duty foil. Sprinkle with paprika. Fold the foil loosely around the potato mixture and seal tightly. Grill on covered grill, turning the packets every 15 minutes, until the potatoes are tender, about 45 to 50 minutes.


  • Partner tip: Reynolds® Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

Fabulous! Loved, loved this recipe ~ everyone did. Made just as written but with 4 green onions for the green pepper. This is reminiscent of scalloped potatoes, but with a very unique and delici...

I'm not sure why others found it bland... We thought it was perfect served with "Kickin' Crunchy Oven 'Fried' Chicken". For the sauce I added garlic powder and used a combination of browned flou...

This was good, and so easy! I bought the wrong pepper- a red one instead of green, but just used it anyway, and it was good in there. The potatoes were cooked to perfection in the time stated ...

This was the dish Recipe Group chose last week, and my husband and I loved it. I added garlic powder only because so many reviewers said it needed it. I baked it, covered, in a 425 degree oven...

Made these for Recipe Group. I didn't want to heat the grill up, so cooked them in the oven. They were just ok. Son didn't like them. Wasn't a whole lot of flavor, just kind of bland. I added ju...

Really tasty! I followed the ingredients as is, and would not change a thing. Rather than using the grill, I did these in the oven at 350 for one hour. Our family all loved this potato casserole...

this was so easy to make and no clean up was a plus. will definetely make again.

We loved these! I opted to bake them in the oven at 350 degrees and they took longer than 50 minutes to cook through. I will cook at higher temp next time or try on the grill. Delicious!!
