Ingredients
- 1 large Yellow Onion (peeled, top and bottom trimmed, hollowed about 3/4 of the way down)
- 4 tablespoons Unsalted Butter (softened for stuffing; additional 2 tbsp melted for sauce)
- 1 teaspoon Cajun Seasoning (store‑bought blend)
- 1 teaspoon Smoked Paprika (adds sweet smoky flavor, not spicy)
- 1 teaspoon Old Bay Seasoning (classic seafood boil seasoning)
- 0.5 teaspoon Garlic Powder
- 0.5 teaspoon Lemon Pepper (provides tangy citrus note)
- 0.25 teaspoon Salt (adjust to taste)
- 0.25 teaspoon Black Pepper
- 1 teaspoon Parsley Flakes (for garnish)
Instructions
Prepare the Onion
Trim the top and bottom of the large yellow onion, peel it, then cut a shallow circle around the middle and scoop out the inner layers, leaving about a ¼‑inch wall so the cavity is roughly three‑quarters of the way down.
Time: PT5M
Stuff the Cavity with Butter
Take 4 Tbsp softened unsalted butter and pack it firmly into the hollowed onion cavity, spreading it evenly to the edges.
Time: PT3M
Make the Boil Sauce
In a mixing bowl melt the remaining 2 Tbsp butter over low heat, then stir in Cajun seasoning, smoked paprika, Old Bay, garlic powder, lemon pepper, salt, black pepper, and parsley flakes until a smooth, aromatic sauce forms.
Time: PT5M
Temperature: Low heat on stovetop
Assemble for Baking
Place the butter‑stuffed onion in the center of a baking sheet or oven‑safe pan, pour the prepared sauce over the onion, then cover tightly with a sheet of heavy‑duty aluminum foil, sealing the edges to trap steam.
Time: PT3M
Bake the Onion
Preheat the oven to 375 °F (190 °C). Bake the covered onion for 45‑50 minutes, until the onion is tender when pierced with a fork and the butter‑spice sauce has caramelized on the surface.
Time: PT45M
Temperature: 375 °F
Finish and Serve
Remove the foil carefully (steam will be hot). Drizzle any remaining sauce over the top, add a final sprinkle of fresh parsley flakes, and serve immediately. Eat with hands or a fork, optionally with steamed rice on the side.
Time: PT4M
