Is your family a rice or potato family?  Our family is a rice family.  Growing up, we ate rice way more often than we ate potatoes!  It probably has something to do with our rich Louisiana Cajun family heritage.  I could literally eat rice every single day!


We eat shrimp and/or seafood much more often during Lent.  Growing up, my dad would do a shrimp boil in our kitchen; pouring the boiled shrimp right into the kitchen sink to drain and cool.  If we weren’t eating shrimp, we were eating catfish, or some sort of fish every Friday. I vividly remember the fish courtbouillon (coo-bee-yawn) that he made.   I also remember my mom would make elbow macaroni with tuna in a red sauce.  Kinda like a tuna spaghetti-mac.  Delicious!



How to Make a Cajun Shrimp and Rice Casserole


Quick Tip:  Buy shrimp that is already peeled and deveined. 


Quick Tip:  Buy the frozen chopped onion, bell pepper, and celery.  Save yourself some chopping time!  But if you prefer to use fresh vegetables, use about 1 cup of chopped onion, 1/2 cup of chopped bell pepper, and 1/4 cup chopped celery. 


Step 1.  Saute the veggies in the butter for about 5 minutes.

Step 2.  Add the shrimp, garlic, and seasonings.  Simmer for about 5 minutes  


Step 3. Stir in the soups and cooked rice (see below “How to Cook Perfect Rice”).  Mix it all up really well.  


Step 4.  Pour into a casserole dish.

Step 6. Serve with french bread and a salad.  Enjoy with a few dashes of hot sauce, if you prefer!

How to Cook Perfect Rice

First, you need to buy extra-long grain rice.  Why?  Because it won’t get sticky or mushy; especially after all the cooking/baking that it has to go through for this recipe.  You want the rice to be firm, yet thoroughly cooked.


Place 2-1/2 cups of water in a 2-quart heavy sauce pan.  Add 1/2 to 1 tsp salt and 1 Tbsp butter to the water.  Bring to a boil.  Stir in 1-1/4 cup of raw rice.  Immediately place the lid on the pan, and turn down the heat to low.  Let the rice simmer for about 20 minutes, or until all the water is absorbed.  No peeking!  When the rice is done, remove the pan from the heat.  Remove the lid and fluff the rice with a fork.


How Long Will Cooked Shrimp and Rice Casserole Last in the Refrigerator?

Any leftovers should last 2-3 days in the refrigerator.  Store in an airtight, covered container.  I like to use the BPA-free glass containers with locking lids.  Check out this 20 piece set of glass food storage containers with snap locking lids. Love these containers!


How to Reheat Cooked Shrimp and Rice Casserole

Personally, I would heat the shrimp and the rest of the casserole separately.  Remove the shrimp from the leftovers and set aside.  Heat the rice casserole to your liking, then warm the shrimp separately.  Don’t overheat the shrimp too much or they will become rubbery. What a shame!  Combine the warmed shrimp with the rest of the rice casserole and enjoy.
