Ingredients

3 to 4 yellow onions enough to cover the bottom of the pan when cut into circles, see instructions
¼ red bell pepper, cut into strips
¼ green bell pepper, cut into strips
1 celery rib, trimmed
⅓ cup olive oil
2 tablespoons melted butter
1 tablespoon minced garlic
1 teaspoon Louisiana hot sauce
¼ teaspoon liquid smoke
1 tablespoon fresh parsley leaves, minced
1 tablespoon fresh celery leaves, minced, optional
salt, black pepper and cayenne pepper to taste

Instructions

Preheat the oven to 300 degrees F.
Peel the onions, then remove the outer edges of each onion's flesh. See post.
Cut each onion into thick circular slices. Arrange onion slices in a single layer in a well-greased enameled cast iron skillet.
Sprinkle the slices liberally with salt, black pepper and cayenne pepper.
Place the red and green bell pepper strips and the celery rib into the bowl of your food processor. Pulse the mixture until finely chopped, then pour into a large bowl.
Pour the remaining ingredients into the bowl with the minced veggies.
Stir until well-combined.
Pour the mixture evenly over the onion slices in the skillet.
Bake uncovered for 1 ¼ to 1 ½ hours, using a spoon to pour the olive oil/butter herb mixture that falls into the bottom of the pan over the onions approximatley every 20 minutes.
Let cool for 5 minutes before serving.

Notes

You can substitute white onions in place of the yellow onions, but not red onions as the recipe just won't turn out the same.
