Ingredients for tuna pot pie
Buttery crust meets creamy tuna filling—just eight ingredients for ultimate comfort.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for flaky crust |
| All-Purpose Flour 🌾 | 2 cups | Plus 2 tbsp for dusting |
| Ice Water 💧 | ½ cup | Chilled for tougher dough |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Canned Tuna 🐟 | 2 cans | 5 oz each, in water |
| Cream of Mushroom Soup 🍄 | 2 cans | 10.5 oz each, condensed |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Sharp cheddar melts best |
| Fresh Mushrooms 🍄 | 1 cup | Sliced, cremini or white |
| Green Onions 🧅 | 3 whole | Sliced, white and green parts |
| Garlic Cloves 🧄 | 2 cloves | Minced for filling |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The crust is non-negotiable here. Plugrá brand butter from the store gives the best flakiness, but any cold, high-fat butter works. If you're in a pinch, Country Crock or Land O'Lakes both work fine. The flour? King Arthur or Gold Medal are my go-tos—they're consistent and give a light texture. Don't skip the ice water; it keeps the dough from getting gummy. I always make the dough first and let it rest while I prep the filling—30 minutes in the fridge makes all the difference for that perfect flaky layer.
No cream of mushroom soup? Homemade version with mushrooms, cream, and flour works even better, but Campbell's or French's are solid shortcuts. The tuna can be oil-packed if you prefer—just drain it well. Swapping cheddar for Gruyère or Swiss adds depth, but cheddar melts perfectly. Fresh mushrooms are ideal, but canned mushrooms work in a pinch. The green onions add a fresh pop, but if you're out, scallions or chives do the trick. Pro tip: Toast the flour in the butter for the crust to add extra flavor without effort.
This pie reheats beautifully—just 10 minutes at 350°F until bubbly. Store leftovers in the fridge for 3-4 days, or freeze portions for up to 3 months. I always make a double batch because it disappears fast. The crust stays crispy if you bake it straight from the fridge—no soggy bottoms here. Garnish with extra parsley right before serving so it stays vibrant.
Why You'll Love This Recipe
- Pantry-to-Table Magic: I swear by this recipe when I’m staring into my fridge at 6:30 PM wondering what to feed everyone. Just five ingredients—no fancy shopping trips—come together while you wait for the crust to blind-bake. The canned tuna might sound basic, but that buttery roux turns it into something actually special.
- Crust So Good: Honestly, the flaky, golden crust is what makes this dish feel like a restaurant meal. You’re not even using pie dough—just butter, flour, and ice water mixed into a shaggy ball. Roll it out, brush it with a little milk, and bake until it’s crisp enough to stand up to a fork. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: This recipe actually tastes better the next day—no sad, soggy pot pies here. The filling thickens just right, and the crust stays crisp if you reheat it properly. I’ve sent this to work in a thermos, packed it for lunch, and even frozen portions for lazy Sundays. No one complains.
- Budget Meal, Big Flavor: Between us, this is my go-to when I need to feed four people for under $10. The canned tuna is the star, but the butter and flour make it feel luxurious. I’ll be real: my daughter picks out the tuna flavor (she’s a picky eater), but she still asks for seconds. That’s the kind of solid, reliable meal I can always count on.
Step-by-step instructions for tuna pot pie
Here's how to build a golden, flaky crust that hugs a creamy tuna filling to perfection.
Make the Flaky Pastry Dough
Start by cutting the 0.75 cup unsalted butter into small cubes and letting them sit at room temperature for about 10 minutes—they should be soft but not melted. In a large bowl, whisk together the 2 cups all-purpose flour and 0.5 teaspoon sea salt. Add the butter cubes and use your fingertips or a pastry cutter to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces.
Sprinkle the 0.5 cup ice water over the mixture, 1 tablespoon at a time, gently tossing with a fork after each addition. Stop when the dough just comes together—it should hold when pressed but still feel slightly crumbly. Avoid overmixing, or the dough will toughen. Shape the dough into a disk, wrap it in plastic, and chill in the refrigerator for at least 30 minutes. This resting time is crucial for developing flaky layers.
Prepare the Creamy Tuna Filling
In a large skillet, melt 2 tablespoons of the remaining butter over medium heat. Add the 1 cup fresh mushrooms, sliced, and cook for 5-6 minutes until they release their moisture and turn golden. Stir in the 2 cloves minced garlic and cook for another 30 seconds until fragrant. Transfer the mushrooms to a mixing bowl and set aside.
In the same skillet, add the remaining 0.5 cup butter and melt over medium heat. Pour in the 2 cans cream of mushroom soup, 0.5 cup heavy cream, and 0.5 cup milk. Stir in the 2 cans drained tuna, breaking it into chunks, and the 1.5 cups shredded cheddar cheese. Cook for 3-4 minutes until the cheese is fully melted and the mixture is smooth. Fold in the cooked mushrooms, 3 sliced green onions, 0.5 teaspoon black pepper, and 0.5 teaspoon dried thyme. Taste and adjust seasoning if needed.
Assemble and Bake the Pot Pie
Preheat your oven to 375°F. On a lightly floured surface, roll out the chilled dough into a 12-inch circle, about 1/8-inch thick. Transfer the dough to a 9-inch pie dish, pressing it gently into the bottom and up the sides. Trim any excess dough, leaving a 1-inch overhang. Spoon the tuna filling into the crust, mounding it slightly in the center.
Roll out the remaining dough to a 12-inch circle and place it over the filling. Trim the edges to match the bottom crust, then crimp the two crusts together using your fingers or a fork to seal. Cut 4-5 slits in the top crust to allow steam to escape. Brush the top crust with a beaten egg (optional, for extra shine) and bake for 40-45 minutes until the crust is golden brown and the filling is bubbling through the slits.
Rest and Serve
Remove the pot pie from the oven and let it cool for 10 minutes before slicing. This resting time allows the filling to set slightly, making it easier to serve without a runny mess. Garnish with 0.25 cup chopped fresh parsley just before serving. The crust should be crisp and flaky, while the filling remains creamy and rich—perfect for a comforting meal.
Serve warm with a side of steamed green beans or a simple salad. The flaky crust and melty cheese combo makes this tuna pot pie a crowd-pleaser, especially on chilly days.
Pro Tips For Making Tuna Pot Pie
- Chill the Tuna First: Drain that canned tuna and pop it in the fridge for 10 minutes before mixing with your filling—it firms up the texture and keeps the pie from turning mushy when you bake it. I learned this the hard way after serving a runny, sad tuna pie that looked more like soup.
- Cut Butter Cold: Use your fingers to chop unsalted butter into the flour before adding ice water—small, pea-sized chunks melt slower and give you a flakier crust. I used to pulse it in a food processor and ended up with a dense, cracker-like top. (Yes, even if you're impatient like me.)
- Skip the Overmixing: Once you add ice water to your dough, stop stirring the second it holds together in shaggy clumps—overworking it makes the crust tough. I was skeptical until I tried it, and now my pot pie crust has that perfect balance of crisp and tender.
- Bake at 375°F, Not Higher: The oven should be at 375°F the whole time—any hotter, and the crust burns before the filling sets. I used to crank it to 400°F for speed, but the top would turn brown while the center stayed wet. (Your future self will thank you.)
Best sauces and condiments for this dish
Creamy Mushroom Sauce
The star of this pot pie is the cream of mushroom soup base, but you can elevate it further. For extra depth, stir in 1 tablespoon Dijon mustard or 1 teaspoon Worcestershire sauce into the filling before baking.
This adds a subtle tang that brightens the richness. I also like adding ½ cup sautéed shallots with the mushrooms for a sweeter, more complex flavor profile. 🍄
Cheesy Upgrade Options
While sharp cheddar is classic, swapping in ½ cup Gruyère or ½ cup smoked Gouda adds a nutty, caramelized depth when baked. For a creamy texture, blend ¼ cup cream cheese into the filling before assembling.
If you love a little heat, fold in ½ teaspoon smoked paprika or ¼ teaspoon cayenne with the cheese. 🧀
Herb and Spice Boosts
Fresh herbs make all the difference. Alongside the dried thyme, add 1 tablespoon chopped fresh dill or 1 teaspoon lemon zest to the filling for a bright, citrusy note. For a smoky touch, sprinkle ½ teaspoon smoked sea salt over the top crust before baking.
I also love a pinch of nutmeg—just ¼ teaspoon—to warm up the flavors. 🌿
Crispy Topping Twists
For a pesto-topped pot pie, mix 2 tablespoons basil pesto with 1 tablespoon cream cheese and spread it over the top crust before baking.
Another favorite is a brown butter drizzle: melt 2 tablespoons butter, brush it on the crust, and sprinkle with 2 tablespoons panko breadcrumbs for crunch. For a savory-sweet contrast, add 2 tablespoons grated Parmesan to the top crust before baking. 🥖
Garnish Game-Changers
Fresh garnishes take this dish to the next level. A sprinkle of toasted breadcrumbs adds texture, while crispy fried shallots bring a gourmet touch. For a pop of color, stir 1 teaspoon turmeric into the filling (it adds a golden hue) or drizzle hot honey over the top after baking.
I also love a final touch of chopped chives or microgreens for freshness. 🌟
Sauce Pairings
Serve this pot pie with a creamy garlic aioli for dipping—mix ¼ cup mayonnaise, 1 minced garlic clove, 1 teaspoon lemon juice, and ½ teaspoon Dijon mustard.
A spicy sriracha mayo (add 1 teaspoon sriracha) is another crowd-pleaser. For a lighter option, a cool cucumber-dill yogurt sauce balances the richness perfectly. 🍽️

Frequently asked questions
Can I use oil-packed tuna instead of water-packed?
Yes, but drain it thoroughly and pat it dry with paper towels first. Oil-packed tuna adds extra richness, so you might want to reduce the heavy cream in the filling by 2 tablespoons to balance the flavors. The texture will be slightly more moist, but still delicious!
How do I prevent a soggy bottom crust?
Prevent sogginess by baking the pie on the lowest oven rack and placing a baking sheet underneath to catch drips. Chill the assembled pie for 20 minutes before baking, and avoid overfilling—the top crust should be 1/4-inch thick at its highest point. Brushing the bottom crust with a beaten egg wash before adding filling also creates a moisture barrier.
Can I make this pot pie ahead of time?
Assemble the pie and refrigerate it for up to 24 hours before baking. For make-ahead convenience, bake it completely, then cool and refrigerate. Reheat at 350°F for 15-20 minutes until warmed through. The crust stays crispy when reheated properly—just cover it loosely with foil to prevent over-browning.
What's the best way to reheat leftovers?
For best results, slice the pie and reheat individual portions in the microwave for 1-2 minutes (covered with a damp paper towel). For oven reheating, cover with foil and bake at 350°F for 10-12 minutes until bubbly. Avoid high heat—it can make the crust rubbery. A quick air fryer session at 320°F for 3-4 minutes also works wonders!
Can I substitute the crust with something else?
For a gluten-free option, use a store-bought gluten-free pie crust or make one with almond flour and butter. For a low-carb version, try a cauliflower crust or simply bake the filling in a buttered baking dish with a sprinkle of crushed pork rinds on top. The filling recipe remains the same—just adjust the baking time by 5-10 minutes if using a different base.
