1-First step: Get everything ready Start by chopping the onion, celery, carrots, potatoes, and sweet potatoes into small pieces that are all close in size. This helps the vegetables cook evenly. Mince or chop the garlic, measure out the herbs, and have the chicken broth, white wine, butter, flour, and pie crust ready before you begin. If you are cooking for a busy weeknight, doing this prep first keeps the rest of the process calm and smooth.

2-Second step: Cook the chicken Place a medium to large skillet over medium heat and add 3 tablespoons of olive oil. Season the chicken tenderloins with salt and pepper, then cook them until they are no longer pink. This usually takes a few minutes on each side, depending on the size of the pieces. Move the cooked chicken to a plate and let it cool enough to handle, then dice it into small pieces that match the size of the vegetables. This makes every bite feel balanced.

3-Third step: Build the flavor base Using the same skillet, add the chopped red onion and garlic. If the pan looks dry, add a little more olive oil from the remaining 1 tablespoon. Cook the onion and garlic until the onion turns translucent. This is where the kitchen starts to smell really good, and the flavor base for your chicken sweet potato pot pie begins to come together.

4-Fourth step: Add the vegetables and herbs Add the carrots, potatoes, celery, sweet potatoes, and frozen vegetables such as peas or corn. Stir in the rosemary, thyme, and sage. These herbs give the pie its warm, homey flavor, and they work well with the sweet potatoes. Cook the vegetables for a few minutes so they start to soften, but keep an eye on them. Some pieces may need a little more time than others, especially if they are cut larger.

5-Fifth step: Deglaze the pan Pour in the white wine, using anywhere from 1/4 cup to 1/2 cup based on how much flavor and liquid you want. As it bubbles, scrape the bottom of the skillet with a spoon to lift up the browned bits. Those bits add a lot of flavor to the filling. Let the wine cook for a minute or two so the sharp edge softens.

6-Sixth step: Make the gravy Push the vegetables to the side of the pan, then add the butter and flour. Cook this mixture for about a minute until the flour turns lightly browned. This step matters because it removes the raw flour taste and helps create a smooth sauce. Slowly pour in the chicken broth, starting with a smaller amount and adding more until the filling thickens into a gravy. The sauce should coat the vegetables but not feel too runny.

7-Seventh step: Mix in the chicken and cool the filling Return the diced chicken to the skillet and stir it through the gravy and vegetables. Taste the filling and adjust the salt and pepper if needed. Then let the mixture cool slightly before adding it to the crust. This is an important step because hot filling can soften the pie dough and make the bottom crust soggy. A short cooling period helps the pie bake up neater and slice more cleanly.

8-Eighth step: Assemble the pie Place the bottom crust into a 9-inch pie pan. Spoon the cooled filling into the crust and spread it out evenly. Moisten the edge of the bottom crust with a little water, then place the top crust over the filling. Seal the edges by pressing them together, then trim any extra dough if needed. Cut 3 to 4 vent slots in the top crust so steam can escape while baking. These vents help the crust stay crisp instead of puffing too much.

9-Ninth step: Bake until golden Bake the pie at 375 to 400 degrees Fahrenheit until the crust turns golden brown. Depending on your oven and the exact thickness of the pie, this may take a bit of watching near the end. If the edges brown too fast, you can loosely cover them with foil. The finished pie should feel hot through the center and smell rich, savory, and slightly sweet from the potatoes.

10-Tenth step: Rest before serving Once the pie comes out of the oven, let it cool for 15 to 20 minutes before slicing. This resting time helps the filling settle, which makes serving much easier. The pie will still be warm, but the slices will hold together better. Serve it on its own or with a simple side salad for a comforting meal.
