Instructions

1
Cut the top and bottom off the sweet onion and peel off the outer skin.
2
Using a small knife, carefully core out the center of the onion, creating a well.
3
Stuff about 1 tablespoon of butter into the cored center of the onion.
4
In a small bowl, place the remaining 1 tablespoon of butter. Add the all-purpose seasoning, paprika, lemon pepper, cayenne pepper, and Old Bay seasoning.
5
Add the chili garlic sauce to the bowl.
6
Grate the garlic clove directly into the sauce mixture and stir everything to combine.
7
Place the stuffed onion onto a large sheet of aluminum foil.
8
Pour the prepared sauce over the top of the onion, ensuring it fills the core and coats the outside.
9
Wrap the onion tightly in the aluminum foil, creating a sealed packet.
10
Place the foil packet in a small baking dish. Bake until the onion is completely tender. (Note: The video does not specify time or temperature. A common method is baking at 400°F / 200°C for 45-60 minutes).
11
Carefully unwrap the hot onion and transfer it to a serving bowl. Pour all the flavorful juices from the foil over the onion.
12
Serve immediately with hard-boiled eggs on the side.

Tips & Notes

Pro tips

Core the onion carefully from the top, leaving at least ½ inch at the bottom to hold the stuffing and sauce.
Use softened butter so it distributes evenly in the cavity; cold butter may not meld with the spices.
Cover the baking dish loosely with foil for the first 30–40 minutes to retain moisture, then uncover to let the sauce reduce slightly and concentrate flavor.

Substitutions

Chili garlic sauce → sriracha or sambal oelek (adjust quantity to taste for heat level)
Old Bay seasoning → Cajun seasoning or Creole seasoning (similar savory-spicy profile)
Paprika → smoked paprika (adds deeper, smokier note)

Storage & make-ahead

Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently in a 325°F oven for 10–15 minutes, or microwave with a splash of water to restore tenderness.

Common Questions

Can you make this onion boil ahead of time?

Yes. Prepare the stuffed onion and sauce up to 24 hours in advance, refrigerate covered, then bake when ready. Add 5–10 minutes to baking time if starting from cold.

What type of onion works best for this recipe?

Large sweet onions like Vidalia, Walla Walla, or Texas Sweet are ideal because they soften quickly and balance the spicy sauce without becoming harsh.
