Tips & Variations
- For Crispier Potatoes: Carefully open the foil packet for the last 5-10 minutes of cooking. This will allow the potatoes to brown and get a little extra crispy.
- Add-ins: Feel free to customize your foil packets! Try adding diced bell peppers, chopped mushrooms, or a sprinkle of fresh rosemary or thyme.
- Protein: Turn this side dish into a full meal by adding chicken sausage, sliced smoked sausage, or even small chunks of chicken breast to the packet before cooking.
Frequently Asked Questions
Can I use different potatoes?
We used Wada Farms Smalls Artisan Mini Potatoes. They are small and round instead of oblong, like fingerlings. The Smalls are perfect for foiled potatoes. However, you can use russet potatoes, red potatoes, or Yukon Gold potatoes. Just be sure to chop them into same size pieces, 1-inch pieces, so they cook evenly.
Can I make these ahead of time?
You can prep the potatoes, onions, and garlic up to a day in advance. Store the mixture in a sealed container in the refrigerator and assemble the foil packets right before cooking.
Do I need to poke holes in the foil?
No, you do not need to poke holes. The sealed foil packet steams the potatoes, making them perfectly tender.
Ingredients
- 1 bag (24 oz) Wada Farms small potatoes, quartered
- ½ yellow onion, diced
- 3-4 cloves garlic, minced
- 2-4 tablespoons olive oil
- Salt and pepper, to taste
- Butter (optional)
Instructions
Preheat your oven to 375°F (if baking) or your grill to medium-high heat.
Tear off a large piece of heavy-duty aluminum foil. For extra security and to prevent tears, you can double up the foil.
Start by washing and drying your potatoes. Quarter each potato, ensuring they are all the same size so they cook evenly.
Place the potatoes, onions, garlic, salt and pepper in the center of the foil. Drizzle generously with olive oil and toss until everything is well-coated.
Fold the foil over the potatoes to create a sealed packet. Make sure to crimp the edges tightly to prevent any steam from escaping.
Cooking Times
How long to bake potatoes in foil (Oven): Place the sealed foil packet on a baking sheet and cook for 35-45 minutes at 375°F. The potatoes are done when they are tender and easily pierced with a fork.
How long to grill potatoes in foil (Grill): Place the sealed packet directly on the grill grates. Cook for 40-50 minutes, flipping the packet every 10-15 minutes to ensure even cooking. Cooking time may vary depending on your grill’s temperature.
