Use a heavy bottom stock pot and place it over medium high heat. Drizzle in your olive oil and heat it up for about one minute.
Gently add your cut up sausage into the pot and sear it for 2-3 minutes, until it is browned on all sides.
Now add your chopped onion into the pot and continuously stir it around until they are softened and translucent, about 3 minutes.
Next, add your minced garlic into the pot with the sausage and onion, and stir it around for about 1 minute (careful not to burn the garlic).
Sprinkle the flour into the pot and stir it in to absorb all of the grease from the olive oil and sausage. Continue to stir for 1-2 minutes to help cook off the flour taste.
Now gently pour your chicken broth into the pot while you continue to stir to make sure the flour is fully incorporated into the liquid.
Gently add in the green beans and the potatoes. Then sprinkle in all of your seasonings including the seasoned salt, Cajun seasoning, garlic powder, black pepper, and onion powder.
Stir the green beans up so that all of the seasonings are combined. Turn the heat down to medium low, and cover the pot with a lid.
Simmer the smothered green beans for 30 minutes, the potatoes should be fork tender. Stir around to help break the potatoes up a bit to thicken the liquid.
Taste to check for seasoning and add salt and pepper to your liking.
Serve right away, and enjoy!
