This recipe for this chicken pot pie appears in the book “Cook It In Your Dutch Oven.”

The delights of classic chicken pot pie are many—from the burnished, flaky crust to the luscious, savory filling.

But putting it together can be a chore: Between making pie dough (which often requires pulling out a food processor), poaching chicken in one pot and building a gravy in another, and then transferring the filling and crust to a pie plate to bake, this comfort food requires a major time commitment, not to mention a battery of pots and pans.

We wanted an easier way and found our trusty Dutch oven to be just the ticket to get us there using only one pot.

Boneless, skinless chicken thighs, cut into pieces, were easy to work with and stayed moist through cooking. While tasters liked the deeper flavor provided by browning the chicken, they weren't keen on the crusty, browned exterior on the pieces—it didn't jibe with the luxurious, creamy filling.

Instead, we simply stirred bite-size pieces of chicken right into the gravy and turned to two powerhouse ingredients—tomato paste and soy sauce—to boost savoriness without being distinguishable in their own right.

To give our pot pie fresh spring flavor we swapped in leeks for onions and stirred in some fresh asparagus, peas, and tarragon after pulling the pot from the oven.

With our one-pot filling perfected, we turned to the crust. Instead of labor-intensive home-made pastry, we decided to use buttery store-bought puff pastry and wove it into a simple but stunning lattice. But no matter what we tried, baking the crust on top of the filling inevitably led to sorry, soggy results.

In the past we skirted this problem by baking the crust separately on a baking sheet, but we were hesitant to add more dishes to our recipe. We realized, however, that the lid of the Dutch oven could act as a stand-in baking sheet: We simply turned the lid upside down before covering the pot and baked the pastry on top. A simple egg wash turned the crust a deep golden. Once we slid the baked crust onto the filling, our simplified centerpiece was complete.

To thaw frozen puff pastry, let it sit either in the refrigerator for 24 hours or on the counter for 30 minutes to 1 hour. We prefer to place the baked pastry on top of the filling in the pot just before serving for an impressive presentation; however, you can also cut the pastry into wedges and place them over individual portions of the filling.

Servings: 6Start to finish: 1 hour, 30 minutes1 (9½-by-9 inch) sheet puff pastry, thawed4 tablespoons unsalted butter1 pound leeks, white and light green parts only, halved lengthwise, cut into ½ inch pieces, and washed thoroughly4 carrots, peeled and cut into ½ inch piecesSalt and pepper½ cup all-purpose flour4 garlic cloves, minced1 teaspoon tomato paste3 cups chicken broth, plus extra as needed¼ cup heavy cream1 teaspoon soy sauce2 bay leaves2 pounds boneless, skinless chicken thighs, trimmed and cut into 1 inch pieces1 large egg, lightly beaten1 pound asparagus, trimmed and cut on bias into 1 inch lengths1 cup frozen peas2 tablespoons chopped fresh tarragon or parsley1 tablespoon grated lemon zest plus 2 teaspoons juiceCut sheet of parchment paper to match outline of Dutch oven lid and place on large plate or upturned rimmed baking sheet. Roll puff pastry sheet into 15-by-11-inch rectangle on lightly floured counter. Using pizza cutter or sharp knife, cut pastry widthwise into 10 1½ inch-wide strips.Space 5 pastry strips parallel and evenly across -parchment circle. Fold back first, third, and fifth strips almost completely. Lay additional pastry strip perpendicular to second and fourth strips, keeping it snug to folded edges of pastry, then unfold strips. Repeat laying remaining 4 pastry strips evenly across parchment circle, alternating between folding back second and fourth strips and first, third, and fifth strips to create lattice pattern. Using pizza cutter, trim edges of pastry following outline of parchment circle. Cover loosely with plastic wrap and refrigerate while preparing filling.Adjust oven rack to lower-middle position and heat oven to 400 F. Melt butter in Dutch oven over medium heat. Add leeks, carrots, and 1 teaspoon salt and cook until vegetables are softened, about 5 minutes. Stir in flour, garlic, and tomato paste and cook for 1 minute.Slowly stir in broth, scraping up any browned bits and smoothing out any lumps. Stir in cream, soy sauce, and bay leaves. Bring to simmer and cook until mixture is thickened, about 3 minutes. Stir in chicken and return to simmer.Off heat, cover pot with inverted lid and carefully place parchment with pastry on lid. Brush pastry with egg and sprinkle with salt. Transfer pot to oven and bake until pastry is puffed and golden brown, 25 to 30 minutes, rotating pot halfway through baking.Remove pot from oven. Transfer parchment with pastry to wire rack; discard parchment. Remove lid and discard bay leaves. Stir asparagus into filling and cook over medium heat until crisp-tender, 3 to 5 minutes. Off heat, stir in peas and let sit until heated through, about 5 minutes. Adjust filling consistency with extra hot broth as needed. Stir in tarragon and lemon zest and juice. Season with salt and pepper to taste. Set pastry on top of filling and serve.
