Potato & Onion Gratin, Barbecue Grill

The theme for Monday Posts in May is Potatoes.

Potatoes are a very misunderstood vegetable. Yes, they are a vegetable, plus they are healthy.

Potatoes have vitamins C and B6, potassium, copper, manganese and dietary fiber. They offer cardiovascular protection, have a potential for lowering blood pressure and have a variety of phytonutrients with antioxidant activity.

This month we are celebrating the the humble potato.

Chez nous we have 6 months (roughly) of winter cooking, which I do in the kitchen and 6 months (roughly) of summer cooking which mon mari does outdoors on one of the barbecue grills or smokers.

This is one of our favorite summer potato recipes.

  1. I have not done this with cheese. I do potatoes, Vidalia or sweet onions, garlic and butter in foil packets on the grill. Same idea. I like Gruyere. I’ll have to try this 🙂

    • As far as the hubs is concerned I can put cheese on everything. It gets a nice, crisp crust when I do them in foil packets…. but really hard to get off the foil, even when I oil it first. lol

    • I think cast iron would work perfectly well. You could add a little water / broth initially and not bother covering them. By the time the liquid cooks off the veggies would be tender and you can just let it brown…. Just a thought lol
