Ingredients

  • onions
  • butter
  • seasoning salt or desired seasoning

Instructions

  1. Quarter the onions without slicing through them completely, so they remain attached at the root.
  2. Spread the onion quarters open like a flower and stuff them with butter and your desired seasoning.
  3. Wrap each stuffed onion tightly with foil.
  4. Place the foil-wrapped onions on the barbecue and cook until they are soft, approximately 30 minutes.

Tips & Substitutions

For the best flavor, consider using a mix of butter and olive oil to stuff the onions. If you don't have seasoning salt, a blend of garlic powder, onion powder, and smoked paprika works well. You can also experiment with adding cheese or bacon bits for extra richness. Make sure to keep the foil tightly wrapped to lock in moisture while cooking on the barbecue.

Serving Suggestions

These barbecue stuffed onions make a fantastic side dish, especially when paired with grilled meats or served alongside a fresh salad. They complement dishes like my Favorite Lemon Pie for dessert or can be enjoyed as part of a vegetarian meal. Serve them with crusty bread to soak up the delicious juices.

Storage & Reheating

Leftover stuffed onions can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply unwrap the onions from the foil and place them on a baking sheet in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through. They can also be microwaved for quicker reheating.

Frequently Asked Questions

Can I use different types of onions for this recipe?

Yes, while yellow onions are commonly used for their sweetness, you can also use red onions for a sharper flavor or sweet Vidalia onions for a milder taste. Each type will give a unique twist to your barbecue stuffed onions.

How can I make these stuffed onions spicier?

To add some heat, consider mixing in crushed red pepper flakes or diced jalapeños with the butter and seasoning. You can also use a spicy barbecue sauce as a stuffing alternative for a kick of flavor.

Can these onions be cooked in an oven instead of on a barbecue?

Absolutely! If using an oven, preheat it to 400°F (200°C). Place the foil-wrapped onions on a baking sheet and cook for about 25-30 minutes, or until they are tender. This method works well if you don't have access to a grill.
