Remove the cabbage core and make six deep cuts around the center, about one-quarter of the way down.
Brush the cabbage with olive oil.
Mix together 1 teaspoon each of garlic powder, smoked paprika, paprika, Cajun seasoning, Old Bay seasoning, and chicken bouillon. Sprinkle evenly over the cabbage.
Squeeze half of the lemon over the cabbage and gently rub the seasoning into every cut and surface.
Place 3 tablespoons of butter in the center of the cabbage.
Wrap tightly with two sheets of aluminum foil and place on a baking sheet.
Bake for 1 hour.
Meanwhile, melt the remaining butter and whisk in the remaining garlic powder, smoked paprika, paprika, Cajun seasoning, Old Bay seasoning, and the remaining lemon juice.
After the first hour, carefully unwrap the cabbage and spoon 1 to 2 tablespoons of the seasoned butter over the top. Rewrap tightly.
Continue baking for another hour until the cabbage is tender.
Let rest for 5 to 10 minutes before serving.
Season with salt and black pepper and serve with the remaining garlic butter for dipping. This Cabbage Boil Recipe is best enjoyed warm.
