How to Make Cajun Seafood Pot Pie
Step 1: Sauté the Aromatics
Start by heating up the butter and olive oil in a large skillet over medium heat. Add your onion, celery, and red bell pepper, sautéing until they’re softened and fragrant—about 4 to 5 minutes. Then toss in the minced garlic, letting it mingle with the veggies for about 30 seconds. This aromatic base is the heart of your Cajun Seafood Pot Pie, so take a moment to enjoy those smells.
Step 2: Make the Roux
Now, sprinkle the flour evenly over the vegetables, stirring well to coat every piece. This turns everything pale and thick—give it a good stir so the flour cooks off that raw flavor and becomes the glue that will hold your creamy sauce together.
Step 3: Build the Creamy Sauce
Slowly whisk in the seafood stock (or chicken broth), making sure lumps don’t form. Let it simmer, stirring all the while, until the mixture is noticeably thicker—about 3 to 4 minutes. Pour in the heavy cream, then add the Cajun seasoning, paprika, thyme, and a sprinkle of salt and pepper. Suddenly, you have a velvety, spice-kissed sauce that’s rich but never heavy.
Step 4: Add the Seafood and Veggies
Fold in the shrimp and crab meat, letting them cook gently until the shrimp just begin to turn pink (about 2 to 3 minutes—don’t overcook). Toss in the corn and peas for a final pop of color and sweet flavor. Take the skillet off the heat so the seafood stays tender.
Step 5: Assemble and Top
Coat a 9-inch deep-dish pie pan or baking dish with a bit of butter or spray, then pour in your luscious seafood filling. Roll out the puff pastry to fit your dish, then gently lay it over the top, trimming the edges as needed and sealing them by pressing gently around the rim. Cut a few small slits in the center with a knife for steam to escape, and brush everything with a beaten egg for that bakery-shop shine.
Step 6: Bake and Rest
Slide your Cajun Seafood Pot Pie into a preheated 400°F (200°C) oven, and bake for 25 to 30 minutes. When the pastry is deeply golden and flaky with the filling visibly bubbling, it’s ready. Let the pie rest for about 10 minutes—this helps everything set so each slice holds together beautifully.
How to Serve Cajun Seafood Pot Pie

Garnishes
For a fresh, herby flourish, sprinkle the finished pie with chopped flat-leaf parsley or a few snipped chives. A dash of extra Cajun seasoning or hot sauce right before serving perks up the flavors even more. A wedge of lemon on the side is a fun touch, offering a little acidity that brightens up each bite of Cajun Seafood Pot Pie.
Side Dishes
While Cajun Seafood Pot Pie is hearty enough to headline your meal, I love it with a crisp green salad—think peppery arugula or baby spinach tossed with a zingy vinaigrette. If you want something extra-festive, try a cornbread muffin or a side of roasted asparagus. The key is to keep sides simple to let the flavors of the pot pie shine.
Creative Ways to Present
For a memorable dinner party, spoon the filling into individual ramekins and top each with a round of puff pastry, making mini Cajun Seafood Pot Pies. Or, if you’re serving a buffet, bake the filling in a cast iron skillet for dramatic, rustic flair. Custom-shaped pastry cut-outs (think crawfish or shellfish designs) are a playful, personal way to dress up the crust.
Make Ahead and Storage
Storing Leftovers
Leftover Cajun Seafood Pot Pie keeps wonderfully in the fridge. Cover the cooled pie tightly with foil or plastic wrap and refrigerate for up to 3 days. The flavors actually meld and deepen overnight, making tomorrow’s supper just as enticing as the first slice.
Freezing
You can freeze the assembled, unbaked pie for up to two months—just wrap it well so the crust stays fresh. When ready to bake, pop the frozen pie straight in the oven (no thawing needed); just add an extra 10–15 minutes to your baking time. Baked leftovers can technically be frozen too, though the crust will be flakier if frozen before baking.
Reheating
To reheat, place your pie in a 350°F (175°C) oven, covered with foil, for about 20 minutes or until hot and bubbly. Remove the foil for the last 5 minutes to crisp up the pastry again. Microwave reheating works for individual portions, but the oven keeps everything tasting and looking its best.
FAQs
Can I use other seafood in Cajun Seafood Pot Pie?
Absolutely! You can easily substitute crawfish, scallops, or even cooked white fish for the shrimp or crab. Just be sure to keep the total amount the same so the filling stays balanced and generously packed.
What if I don’t have seafood stock?
Chicken broth works perfectly in a pinch and still gives you a richly flavored sauce. If you want even more seafood depth, toss in a splash of bottled clam juice or add a bit of fish sauce to your broth.
Can I make this recipe ahead of time?
Yes—assemble the Cajun Seafood Pot Pie up to the point of adding the pastry, then refrigerate (covered) for up to 24 hours. Add the pastry and egg wash just before baking for the freshest, flakiest top.
Is there a dairy-free option?
To make it dairy-free, substitute a plant-based butter and use full-fat coconut milk or unsweetened soy creamer in place of the cream. Check your puff pastry label, as some brands are made without dairy.
How spicy is Cajun Seafood Pot Pie?
The heat level depends on your Cajun seasoning blend. If you’re spice-sensitive, start with half the called-for seasoning and taste as you go. Add cayenne or hot sauce at the table for those who love extra kick!
