If you’re craving something rich, savory, and soul-satisfying, my Cajun Seafood Pot Pie is a must-try. Growing up in Youngsville, Louisiana gave me a great palate for all things Cajun, and this dish is a cozy spin on a Southern classic; loaded with crawfish, shrimp, and crab in a creamy, spicy filling, all topped with golden puff pastry. This is the kind of dish that brings people together and leaves no leftovers behind.
Whether you’re feeding a crowd, celebrating a special occasion, or using up leftover seafood boil from the freezer, this pot pie turns simple ingredients into something unforgettable.
Why You’ll Love This Cajun Seafood Pot Pie
Pantry-Friendly & Freezer-Smart: Most of the ingredients are fridge or pantry staples; and if you’ve saved seafood from a previous boil, you’re halfway there.
Comforting & Flavorful: With sautéed Cajun aromatics, golden roux, and creamy seafood filling, this pot pie is the kind of food that makes people ask for seconds.
Customizable: Use whatever seafood you have on hand. Crawfish tails, shrimp, crab; it’s all fair game. This is a “clean out the freezer and impress the guests” kind of recipe.
Step-by-Step Guide to Emilie’s Cajun Seafood Pot Pie
1. Preheat Your Oven
Set your oven to 400°F. Make sure the rack is in the center position so your puff pastry bakes evenly.
2. Dice and Mix Your Vegetables
Chop up the following:
Yellow onion
Red bell pepper
Green onions
Celery
Garlic
Fresh parsley
Combine everything in a large deli container or bowl. Give it a shake or toss to evenly mix.
3. Sauté the Vegetables
Heat olive oil in a large cast iron skillet over medium heat. Add about ¾ of your prepped veggie mix (freeze the rest for next time!). Cook, stirring occasionally, until softened. Adjust the heat if needed to avoid browning or burning.
4. Optional: Deglaze with White Wine
For extra flavor and to preserve your skillet, transfer the sautéed vegetables to a saucepan. Add a splash of white wine and cook until evaporated. This helps balance the flavors and removes any acidity that could harm your cast iron.
5. Start the Roux
Return the veggies to the skillet. Over medium-low heat, add butter and let it melt. Sprinkle in flour and stir constantly until it forms a smooth roux with a light golden color. Don’t rush this step, it builds the base flavor.
6. Add the Seafood Stock
Gradually pour in seafood stock, about ½ cup at a time, stirring constantly. Try not to break your roux! Let it simmer for 5–10 minutes until the mixture thickens slightly. Keep stirring so it stays smooth and lump-free.
7. Finish the Filling
Turn off the heat. Stir in:
Heavy cream
Crawfish tails
Crab meat
Shrimp
Cubed golden potatoes
Then grate in sharp cheddar cheese to your liking, I like it extra creamy! Add a capful of crab boil seasoning and season to taste with your favorite Cajun seasoning.
Pro Tip: If your seafood was already seasoned from a boil, go lighter on the extra Cajun seasoning.
8. Top with Puff Pastry
Lay a sheet of puff pastry over the skillet. Trim any overhanging edges, but leave a little to crimp around the sides, it helps hold the pastry in place. Cut a small “X” in the center to let steam escape. Brush the top of your pastry with egg yolk for golden perfection.
9. Bake to Perfection
Place your skillet in the oven and bake for 35–40 minutes, or until the pastry is golden brown and crisp. Let it cool for 5–10 minutes before serving.
A Few Extra Tips
Make Ahead: The filling can be made a day ahead. Just store it in the fridge and top with pastry right before baking.
Use What You Have: No crawfish? Just double up on shrimp. No crab? Add more potatoes and cheese.
Save That Seafood: After a boil, peel and freeze leftover seafood for recipes like this. It’s the best way to stretch a feast into multiple meals.
Puff Pastry: I made my own puff pastry, which I will soon post, but feel free to buy your puff pastry.

Ingredients
Method
- Dice the yellow onion, red bell pepper, green onions, celery, garlic, and parsley. Combine all the chopped vegetables in a large deli or storage container. Give it a good shake or mix to combine.
- Heat olive oil in a large cast iron skillet over medium heat. Add the prepped vegetable mix and cook, stirring occasionally, until softened (I added about 3/4 the container and froze the rest). Be careful not to let the vegetables burn, lower the heat slightly if needed.
- (Optional but Recommended) For added flavor and to protect your cast iron, you can transfer the cooked vegetables to a saucepan. Add the white wine and cook until it’s fully evaporated. This prevents the acidity from stripping your cast iron.
- Return the vegetables to the cast iron skillet. On medium low heat, add butter and allow it to melt completely. Stir in the flour and cook, stirring constantly, until the flour develops a light golden color. Be careful not to burn it.
- Slowly pour in the seafood stock, about ½ cup at a time, stirring constantly to maintain a smooth consistency and prevent the roux from splitting. Turn your heat up to medium to let it simmer for 5–10 minutes until slightly thickened.
- Turn off the heat and stir in the heavy cream. Mix well to incorporate.
- Stir in the crawfish tails, crab meat, shrimp, and cubed golden potatoes.
- Grate in sharp cheddar cheese to taste, I like mine extra creamy, so I go generous. Add a capful of crab boil and season with Cajun seasoning to your liking. If your seafood wasn’t pre-boiled, use more seasoning to boost the flavor. (Tip: This dish shines when made with leftover seafood boil from the freezer.)
- Drape the puff pastry sheet over the top of the skillet, trimming any long overhangs but leaving a bit extra to crimp around the edge. This helps keep the pastry in place while baking. Cut a small “X” in the center to allow steam to escape.
- Place the skillet in a preheated 400°F oven. Bake for 35–40 minutes, or until the puff pastry is golden brown and crisp.
