1-First Step: Mise en place and setup Gather and measure all ingredients. Dice 1 large yellow onion, 1 green bell pepper, and 1 bunch of celery (leaves included). Chop green onions and parsley, and mince 2-3 cloves garlic. Slice the 12-ounce package of Andouille sausage into coins. Shred meat from 1 rotisserie chicken and keep 2 cups of raw or pre-cooked shrimp ready. Place a large, heavy-bottom stock pot or stainless steel Dutch oven on medium-low heat for the roux. Have a separate skillet for browning sausage and a ladle and whisk nearby. If you plan to use okra, slice 1 cup and set aside.

2-Second Step: Make the roux (critical for any Cajun gumbo recipe) Combine 1 cup all-purpose flour and 2/3 cup vegetable or canola oil in the stock pot. Stir constantly over medium-low heat for 30 to 45 minutes until the mixture turns dark brown like chocolate and reaches a soft dough-like consistency. Keep the heat moderate to prevent burning. If the roux starts to dry out or thin too much, add a little more flour or oil as needed. Tip: Use a wide pot so the roux cooks evenly. The color change is the most important cue; taste will be nutty, not burnt. Cook slowly for deep color and flavor. A dark roux is what gives authentic New Orleans gumbo its signature taste.

3-Third Step: Brown the sausage and deglaze While the roux cooks, heat a skillet over medium-high. Add the sliced Andouille sausage in a single layer and brown each side. Remove browned sausage to a plate. Pour 1/2 cup chicken broth into the hot skillet to deglaze, scraping up browned bits, then pour that liquid into the roux pot. This step adds concentrated flavor from the sausage drippings to the gumbo base. If using kielbasa, follow the same method.

4-Fourth Step: Add broth and vegetables Pour the remaining 5 1/2 cups chicken broth into the roux pot for a total of 8 to 10 cups depending on your preferred thickness. Add the diced celery, green bell pepper, yellow onion, green onions, parsley, garlic, and optional 1 cup okra. Stir well to combine. Bring to a gentle boil, then reduce to a simmer and cook for 5 to 7 minutes until vegetables are slightly tender, skimming any foam that rises to the surface. Adjust the heat so the pot barely bubbles. Over-boiling can break down flavors and make the gumbo cloudy.

5-Fifth Step: Season and add seafood Stir in 1 to 2 tablespoons Cajun seasoning (start with less if you are sensitive to heat). Add 2 cups uncooked shrimp to the pot and cook for about 2 minutes until they turn pink and curl. If your shrimp are pre-cooked, add them later with the shredded rotisserie chicken so they just warm through.

6-Sixth Step: Combine proteins Stir in the shredded rotisserie chicken and the browned Andouille sausage. Taste and adjust seasoning with salt, pepper, or chicken bouillon paste for added depth. If the gumbo seems too thick, add extra broth to reach the desired consistency. Cook a few more minutes to marry flavors.

7-Final Step: Serve and rest Serve the gumbo hot over cooked rice and garnish with chopped green onions and parsley. Leftovers improve overnight as flavors meld, so consider making this gumbo a day ahead for even better depth. Flavors typically taste richer on day two.
