[Cassava Flour Roux] Seafood Gumbo

Okay, y’all! I’ve finally made a grain-free/gluten-free gumbo using Cassava Flour to make the roux– and it turned out fabulous! You’re going to love this Seafood Gumbo!

In case you are new here, I’ve had a Whole30 Chicken and Sausage Gumbo on the blog for a long time. To keep it Whole30– I used Arrowroot to thicken the soup but I really never made a traditional roux–  more of a faux roux to keep the dish grain-free and gluten free but also get all the yummy gumbo flavors. It’s a super simple recipe that’s perfect for any weeknight. If you’re looking for more of a “gumbo soup” that’s whole30 compatible and paleo friendly– definitely try this recipe.

This rendition, however, starts off by making a more traditional roux by swapping out  Cassava Flour + avocado oil in place of all purpose flour + vegetable oil. Just as making any roux for a gumbo– it’s a bit cumbersome and time consuming, but totally worth it. You just need to be patient and enjoy the process!  A good roux takes time–and when I make it with cassava it takes anywhere between 20 to 30 minutes.  If you want to compare color, take out a jar of peanut butter and a copper penny before you start.  Relax and enjoy the process, it’ll be worth it! 

This is such a fun celebratory dinner to make over the holidays or on a chilly Sunday for supper. And, once you have the base down– you can really add whatever filling you’d prefer. Chicken and sausage is great, but here i’ve made a seafood rendition using Sausage, Shrimp, Crab, and Oysters. It’s delicious.

Total Time1 hr

Ingredients

  • ¾ cup + 1 tbsp avocado oil
  • ¾ cup cassava flour
  • 1 cup diced green bell pepper about 1 medium pepper
  • 1 cup diced yellow onion about ½ large onion
  • 1 cup diced celery about 2 stalks
  • 3 cloves garlic minced
  • 4 cups seafood stock
  • ½ tsp dried thyme
  • ½ tsp dried oregano
  • ½ tsp cayenne
  • 1 tsp kosher salt plus more to taste if desired
  • ½ tsp white pepper black pepper is fine, also
  • 1 bay leaf
  • 1 cup frozen cut okra
  • 12- ounces store-bought fully cooked andouille sausage or kielbasa thinly sliced
  • 1 lb peeled and deveined shrimp
  • 8 ounces lump crab meat
  • 8 ounces small oysters in their liquor I buy the cartons from Central Market
  • Freshly chopped parsley leaves optional for serving

Instructions

  • Preheat the oven to 375 degrees F and line a baking sheet with parchment paper. Set aside.
  • Heat a large pot, preferably a Dutch oven, over medium heat. Add ¾ cup of the avocado oil and ¾ cup of the cassava flour and stir until well combined and there are no longer any clumps. Cook, constantly stirring, browning the flour until it is a dark reddish/brown in color. This can take anywhere from 20 to 30 minutes depending on how hot your stovetop is. You *do not* want the stovetop too hot. Medium/medium-low is best to ensure you slowly brown the roux without burning it.
  • When your roux is a nice brown color (think peanut butter or a copper penny), add the bell pepper, onion, celery, and garlic and stir until well combined (it will thicken quickly) and continue to cook—browning the roux just a tad more and softening the vegetables, about 3 more minutes.
  • While stirring, pour in 4 cups of the seafood stock until well incorporated. Add the thyme, oregano, cayenne, salt, pepper and bay leaf and stir to combine. Bring the pot to a rapid simmer, then reduce the heat to a lighter simmer over medium-low heat, cover, and let cook while you prepare your okra, stirring occasionally.
  • Place the frozen okra on the prepared baking sheet and drizzle with the remaining 1 tbsp of avocado oil. Transfer to the oven and roast until golden, about 20 minutes.
  • Meanwhile, slice up your andouille sausage and add to the gumbo, stir to combine, cover and continue cooking while your okra is roasting.
  • When the okra is done roasting, add to the gumbo.
  • About 5 minutes prior to serving—get ready to add your seafood. When ready to add the seafood, increase your heat and bring to a rapid simmer, uncovered. Add the shrimp, crabmeat and undrained oysters and stir to combine.. Cook until the shrimp is just cooked through, about 3 minutes. Remove from heat, taste and add salt, if desired and serve immediately.
  • To serve, I use a ¼ cup measuring cup to scoop up the steamed white rice and place it in a mound in a bowl. Spoon approximately 1 cup of the gumbo around the rice. Garnish with freshly chopped parsley, if desired. Serve and enjoy!

    When I use cassava flour, it always turns out gluey – what am I doing wrong?

      cook it longer and slower– it really needs to cook down!

    What other flour could we swamp in lieu of cassava? Would ratios better similar?

    Can you substitute the crab for something less expensive?

    Do you thaw the frozen okra before roasting it?

        This looks amazing, and I’m from South Louisiana so I know a good gumbo when I see one. 😉 Are the oysters you used smoked from a can or fresh?

    Making this right now and it smells SOOOO good! I’m a south LA girl too so that says a lot. Instead of oysters, I am doubling up on crabmeat. Can’t wait to eat this tonight!

    Do you think it would be alright to make the roux and everything the day before and then add the seafood the next day when I reheat?

      Yes! that could work just fine! Just make the base of the gumbo (roux + holy trinity + seafood stock + seasonings and even the andouille sausage). Then, reheat on the stovetop over medium heat until simmering and you can add the seafood right before ready to serve. Will be great (and will give the gumbo extra time to really mend those nice flavors).

        If I’m only doing shrimp and andouille so I change the broth amount?

    This was great. I never knew canned oysters would work so well in a gumbo. Then the next couple of days I made oyster stew and crab arugula pasta!

    Serving 17. If I put that number in the servings calculator, are all measurements good to go?

      Hi Shelley–
      Most everything should be okay; however, you may not need as much broth as it calls for or as much salt– but this is something you can season to taste + you can also just make sure your gumbo doesn’t get too thin (you still want some body to it) by adding the broth in one carton at a time until the consistency looks nice.

    Can you omit the oysters all together or what would be a good replacement?
