Start by shredding the rotisserie chicken into bite-sized pieces, ensuring to remove any skin. Chop the red potatoes into small, even pieces to ensure they cook uniformly.
In a large pot or Dutch oven, add a splash of olive oil over medium heat. Add the dried minced onion flakes and sauté for about 2 minutes until they become fragrant.
Add the shredded chicken, chopped potatoes, frozen lima beans, frozen corn, and chicken broth into the pot. Stir well to combine all ingredients.
Pour in the tomato sauce, followed by the sugar, salt, pepper, ground red pepper, oregano, and poultry seasoning. Mix everything together until well incorporated.
Bring the stew to a gentle boil, then reduce the heat to low. Cover the pot and let it simmer for about 30-40 minutes, stirring occasionally. This allows the flavors to meld beautifully.
After simmering, taste the stew and adjust the seasoning as needed. You might want to add a pinch more salt or pepper depending on your preference.
Ladle the Brunswick Stew into bowls and serve hot. It pairs wonderfully with crusty bread or cornbread, making it a complete meal!
