Method
Make the filling
- Heat the oven to 400°F.
- Lightly grease a 2-quart baking dish.
- Melt the butter in a large saucepan over medium heat.
- Add the onion and carrots and cook for 5–7 minutes, stirring occasionally, until softened.
- Stir in the flour and cook for 1 minute.
- Gradually whisk in the broth and milk, then add the salt, pepper, and thyme.
- Simmer for 3–5 minutes, stirring, until thickened.
- Gently stir in the peas and drained tuna.
- Transfer the filling to the prepared baking dish.
Top and bake
- Lay the puff pastry over the filling and trim it to fit with about a 1-inch overhang.
- Tuck the edges against the inside rim of the dish.
- Cut 4 small vents in the top.
- Bake for 25–30 minutes, until the pastry is puffed and golden and the filling bubbles through the vents.
- Rest for 10 minutes before serving.
Notes
For a crisp topping, keep the thawed puff pastry cold until you place it over the filling. Refrigerate leftovers for up to 3 days; freezing is possible, though the pastry may lose some crispness. For a dairy-free variation, use plant-based butter and unsweetened non-dairy milk.
