Step‑by‑Step Instructions for Easy Roasted Cajun Onion Boil

Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This temperature allows your onions to roast gradually, ensuring they become tender and flavorful. As the oven warms, gather your baking dish or cast iron skillet, which will cradle the onions during their roasting journey, making cleanup a breeze.

Step 2: Prepare the Onion
While the oven heats, take a large onion and slice off the top center to create a small well. This well is essential for holding the delicious butter and Cajun seasoning. Use a spoon to scoop just enough of the inner onion out, leaving the layers intact for a stunning reveal later.

Step 3: Season the Onion
Place a generous pat of butter in the well you created and sprinkle in your Cajun seasoning along with a touch of salt. Feel free to be adventurous with the amount of seasoning, as this will contribute to the richness of the Easy Roasted Cajun Onion Boil. Now, it’s time to wrap the onion tightly!

Step 4: Wrap the Onion
Carefully wrap your seasoned onion in aluminum foil, ensuring it’s completely sealed to trap all the flavors during roasting. This step is crucial to allow steam to build up, resulting in a beautifully tender onion by the time it’s cooked. Place the wrapped onion in your chosen baking dish or skillet before heading to the oven.

Step 5: Roast the Onion
Transfer the baking dish to the preheated oven and roast the onion for about 1 hour. As it cooks, keep an eye out for the onion turning fork-tender and becoming lightly caramelized. If after an hour it hasn’t reached the desired softness, reseal and return it to the oven for additional roasting.

Step 6: Broil for Extra Caramelization
For an exquisite finish, set your oven to broil after the onion has softened. Unwrap the foil carefully to avoid steam and drizzle a bit more butter over the top. Broil for 5-10 minutes, watching closely as the outer layers caramelize beautifully. This step adds wonderful texture and depth to your Easy Roasted Cajun Onion Boil.

Step 7: Serve and Enjoy
Once your onion has achieved a golden-brown exterior, take it out and let it rest briefly. Serve it on a plate, allowing the flavorful juices to pool around the base. This savory treat pairs perfectly with rice, crispy chickpeas, or any roasted veggies, making it a delightful addition to your meal.

How to Store and Freeze Onion Boil

Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days, ensuring the onion retains its delicious flavor and texture.

Freezer: For longer storage, wrap the cooled onion tightly in plastic wrap and then foil, freezing for up to 2 months. Thaw in the fridge before reheating.

Reheating: Gently reheat in the oven at 350°F (175°C) for about 15-20 minutes to restore its tender texture without drying out.

Freshness Tip: If possible, consume within the first few days for the best taste from your Easy Roasted Cajun Onion Boil!
