Instructions

1
Cut the ends off the onions, peel them, and use an apple corer or knife to remove the center core, creating a hole.
2
In a small bowl, melt 2 tablespoons of unsalted butter.
3
To the melted butter, add the garlic powder, Cajun seasoning, Old Bay seasoning, paprika, chili powder, lemon pepper seasoning, sugar, dried parsley, lemon juice, and minced garlic.
4
Mix all the sauce ingredients together until well combined and set aside.
5
Cube the remaining 1 tablespoon of butter.
6
Place each cored onion on a large piece of aluminum foil.
7
Insert one chicken bouillon cube into the hole of each onion, followed by the cubed butter, dividing it evenly between the two onions.
8
Spoon the prepared Cajun butter sauce into and over the top of each onion.
9
Wrap each onion tightly in its foil packet and place them in a baking dish.
10
Bake at 350°F (175°C) for 60 minutes.
11
Carefully unwrap the onions and transfer them to a serving plate.
12
Pour any remaining juices from the foil packets over the onions.
13
Garnish with fresh parsley and serve immediately, optionally with rice.

Tips & Notes

Pro tips

Choose large, firm onions of similar size so they bake evenly; cut a thin slice from the root end to create a flat, stable base.
Mix the butter with all seasonings before stuffing to ensure even distribution of Cajun flavors throughout the filling.
Wrap each onion tightly in foil to trap steam and cook the onion through while keeping the butter moist and flavorful.
Don't skip the bouillon; it adds savory depth that complements the Cajun spice blend and enriches the cooking liquid.

Substitutions

Unsalted butter → salted butter (reduce added salt if any)
Cajun seasoning blend → store-bought Cajun seasoning (1–1.5 tsp, to taste)
Old Bay seasoning → additional paprika or smoked paprika (1/4 tsp)
Dried parsley → fresh parsley (1 tbsp chopped, added after baking for fresher flavor)

Storage & make-ahead

Store leftover baked onions in an airtight container in the refrigerator for up to 3 days. Reheat gently in a foil-covered dish at 350°F for 10–15 minutes, or microwave until warmed through.
