Follow these easy steps to make your own Onion Boil:

Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
Prepare the Onions: Using a melon baller or a small spoon, scoop out the top center of the onions (about halfway down), creating a “well” in the center to hold the seasonings.
Add Butter to the Onion Wells: Place each onion on a sheet of aluminum foil. Add 1 tablespoon of butter into the middle of each onion’s well.
Make the Seasoning Mix: In a small bowl, melt the remaining 2 tablespoons of butter in the microwave. Add the paprika, Old Bay seasoning, cajun seasoning, Italian seasoning, salt, black pepper, crushed garlic, and chili onion crunch (or red chili flakes). Stir the mixture well until fully combined.
Pour the Seasoning Over the Onions: Pour the seasoning mixture evenly over the onions, letting it drip down the sides.
Wrap and Roast: Tightly wrap each onion in foil and place them in a baking dish or cast-iron skillet to catch any drips. Roast the onions for 50-55 minutes on the center rack. Check for tenderness; if needed, bake for an additional 10 minutes until the onions are fork-tender.
Optional Broiling: For a caramelized top, turn the oven to broil. Open the foil, drizzle a little more butter or olive oil, and sprinkle extra salt. Broil for 2-3 minutes, watching carefully until the top is golden brown and crispy.
Serve and Enjoy: Peel away the outer layers of the onion and enjoy each soft, flavorful layer. Don’t forget to pour any delicious juices from the foil over the onions for extra flavor.

Pro Tips for Perfect Onion Boil

Use Sweet Onions: For the best flavor, stick with sweet onions like Vidalia or Walla Walla. These types will caramelize beautifully and provide the perfect balance of sweetness and savory depth.
Customize Your Spices: Don’t hesitate to adjust the seasonings based on your personal preferences. You can add more chili onion crunch for extra heat or experiment with other spices like garlic powder or thyme for a unique twist.
Monitor the Broiling Step: If you decide to broil the onions, keep a close eye on them. Broiling can quickly go from golden brown to burnt, so watch for that perfect crispy finish.

Serving Ideas or Usage Tips

Onion Boil is incredibly versatile and can be enjoyed in many ways:

As a Side Dish: Pair this flavorful onion with grilled meats, roasted chicken, or fish for a savory, satisfying side. The sweetness and spices balance well with a variety of main dishes.
Snack Time: Perfect for a quick snack or appetizer! The caramelized onions, combined with the seasonings and buttery goodness, make it a savory treat that’s hard to resist.
Topping for Sandwiches or Burgers: Slice the onion after baking and use it as a topping for sandwiches, burgers, or even salads. Its rich flavor adds depth to any dish.
Great for Meal Prep: This dish is easy to make ahead of time and can be stored in the fridge for a few days, making it ideal for meal prepping. Just reheat in the oven for a few minutes before serving.

Storage Advice or Shelf-Life Information

To keep your Onion Boil fresh:

Refrigeration: Store leftover Onion Boil in an airtight container in the refrigerator for up to 3 days. The onions will maintain their flavor and texture, though they may soften slightly upon reheating.
Freezing: Freezing is not recommended as the onions can become mushy after thawing. For the best flavor and texture, enjoy them fresh or refrigerated.
Reheating: To reheat, place the onion in a baking dish and cover with foil. Heat at 350°F (175°C) for 10-15 minutes, or until warmed through. You can also microwave individual portions.
