How to Make Onion Boil
-
Preheat your oven to 375°F. This will prepare the perfect environment for our sweet onions to turn tender and delicious.
-
Prepare the onions by peeling them and cutting a hole in the top about 1-inch in diameter. Carefully scoop out the center with a small spoon to create a well—this is where all the flavor will go!
-
Place pieces of the butter into the center of each onion. You’ll add a luscious richness to every bite of this Onion Boil.
-
Melt the remaining tablespoon of butter in a small microwave-safe bowl. Mix in the chili onion crunch, minced garlic, paprika, Old Bay seasoning, Cajun seasoning, Italian seasoning, salt, and pepper. This flavorful mixture will fill the onions with zest!
-
Pour the mixture evenly into the wells of each onion, filling them to the brim and spreading a bit over the sides for extra flavor infusion.
-
Wrap each onion tightly in foil and place them in a baking dish. This keeps all those lovely flavors inside as they bake.
-
Bake the onions for 50-60 minutes, or until they’re fork-tender. After 50 minutes, check for tenderness and continue baking if necessary, checking every 10 minutes.
-
Unwrap the foil from the tops of the onions. If desired, add a little more melted butter and seasonings to enhance the flavor.
-
Broil (optional) by setting the oven to broil and returning the onions for an additional 2-3 minutes. This will caramelize the tops for a delicious finish.
Optional: Drizzle with balsamic glaze for an extra touch of sweetness.
