Method
 

Step-by-Step Instructions for Onion Boil
  1. Preheat your oven to 375°F (190°C). Gather your ingredients, baking dish, aluminum foil, and chosen seasonings.
  2. Take a large, firm onion and scoop out about ⅓ of the top to create a well. Place the onion on aluminum foil.
  3. Fill the well in the onion with butter. Drizzle olive oil and Cajun seasoning over the butter, distributing evenly.
  4. Wrap the onion tightly in aluminum foil, sealing in moisture and flavor. Place it in a baking dish.
  5. Roast the onion in the preheated oven for about 1 hour, until fork-tender and slightly caramelized.
  6. Optionally, broil for 5-10 minutes for added flavor and texture, watching closely to prevent burning.
  7. Remove from the oven, let cool slightly, unwrap, drizzle the collected juices over top, and serve warm.
