Why This Onion Boil Delivers
Sweet onions become meltingly soft when cored, stuffed with a garlic-paprika-butter blend, and slow-baked in foil packets. The natural sugars caramelize while absorbing bold seasonings like Old Bay and thyme for restaurant-quality flavor at home. High in fiber and vitamin C, each onion offers satisfying nutrition with minimal effort. Budget-friendly and naturally gluten-free, it adapts easily to vegan or spicy preferences.
Ingredients
Makes 4 servings (1 onion each). Prep Time: 15 minutes. Cook Time: 60 minutes. Total Time: 1 hour 15 minutes.
- 4 large sweet onions (Vidalia or yellow, about 10 ounces each)
- 1/2 cup unsalted butter, softened (or vegan butter)
- 1 tablespoon garlic powder
- 4 teaspoons smoked paprika
- 2 teaspoons Old Bay seasoning
- 2 teaspoons kosher salt
- 1 teaspoon dried thyme
- 1 teaspoon black pepper
- Optional: 1 teaspoon cayenne for heat
- Chopped parsley and lemon wedges, for serving
Step-by-Step Instructions
Follow these simple steps for foolproof results. Use heavy-duty foil for best steaming effect.
- Preheat oven to 375°F. Line a baking sheet with foil or place directly on rack for easy cleanup.
- Trim root ends of onions flat. Peel outer layers. Use a melon baller or spoon to core out centers about 1/2-inch deep, creating a cavity (save cores for stock if desired).
- In a bowl, mash softened butter with garlic powder, paprika, Old Bay, salt, thyme, pepper, and cayenne until smooth.
- Stuff 2 tablespoons seasoned butter into each onion cavity. Spread 1 tablespoon more over tops and sides.
- Wrap each onion tightly in a 12×12-inch foil square, sealing edges to trap steam.
- Bake 55-65 minutes until fork-tender (medium onions: 50 minutes; large: 65 minutes). Check one to confirm.
- Rest foil packets 5 minutes. Unwrap carefully (steam hot), baste with pan juices, and garnish with parsley.
Pro Tip: Slice open tableside to reveal steamy layers. Serve juices spooned over rice or crusty bread.
