How to Make Onion Boil – Step-by-Step Directions
Step 1 – Prepare Ingredients
Begin by preheating your oven to 375°F. Next, peel the large sweet onions, removing the outer layers until they’re smooth and clean. Use a paring knife to cut a hole in the top of each onion, approximately 1-inch in diameter, being careful not to pierce the bottom.
Step 2 – Scoop Out the Center
Take a small spoon or a butter knife to scoop out the center of each onion. Aim to create a well that extends halfway down into the onion. This step is crucial as it provides space for the delightful mix of spices and butter, enhancing the flavor.
Step 3 – Add Butter
Slice 1 tablespoon of butter into two pieces and place one piece in the well of each onion. This will melt during baking and infuse the onion with rich, creamy flavor.
Step 4 – Prepare the Spice Mix
In a small microwave-safe bowl, melt the remaining 1 tablespoon of butter in the microwave. Once melted, add the chili onion crunch, minced garlic, paprika, Old Bay seasoning, Cajun seasoning, Italian seasoning, salt, and black pepper. Stir the mixture well to combine all the flavors.
Step 5 – Fill the Onions
Pour the seasoned butter mixture evenly over the two onions, ensuring it fills the wells. Don’t hesitate to spread a bit of the mixture over the sides of the onions for extra flavor and color.
Step 6 – Wrap and Bake
Wrap each onion tightly in aluminum foil and place them in a baking dish. This will keep them steamy as they cook, ensuring tenderness and flavor infusion.
Step 7 – Baking Time
Place the dish in the preheated oven and bake for about 50-60 minutes. Keep an eye on them; check for fork tenderness at the end of the baking time. If they’re still firm, continue baking, checking every 10 minutes until the desired tenderness is achieved.
Step 8 – Add Final Touches
Once the onions are tender, peel back the foil from the top. If desired, drizzle some more melted butter and sprinkle a bit more seasoning over the tops for an extra flavor boost.
Step 9 – Optional Broiling
For a delightful finish, set the oven to broil and return the onions back to the oven. Broil for 2-3 minutes to lightly caramelize the tops, creating a visually stunning and deliciously crisp finish.
