- Make the herb butter. In a small bowl, mash the 8 tablespoons of cold butter with the parsley, dill, grated garlic, and 1/2 teaspoon salt until evenly combined.
- Lay a sheet of plastic wrap on the counter, scrape the butter onto it, and roll it into a tight log about 5 inches long and 1 inch thick. Twist the ends shut and freeze for at least 30 minutes, until rock solid.
- Trim any tenderloins or loose flaps from each chicken breast. Place one breast between two sheets of plastic wrap and pound with a meat mallet, working from the center outward, until the breast is an even 1/4 inch thick. Repeat with the remaining breasts.
- Season both sides of each pounded breast with the 1 1/2 teaspoons salt and the black pepper.
- Slice the frozen butter log crosswise into 4 equal pieces. Place one piece in the center of each chicken breast, set toward the wider end.
- Fold the long sides of the chicken inward over the butter, then roll up tightly from the wider end, tucking as you go so the butter is fully sealed inside with no gaps. Press the seam to close.
- Set up a breading station with three shallow bowls: flour in the first, eggs beaten with the milk in the second, and breadcrumbs in the third.
- Roll each chicken parcel in the flour, shaking off the excess, then dip in the egg, then coat thoroughly in breadcrumbs, pressing the crumbs into the surface.
- For an extra-secure double crust, dip each breaded parcel back into the egg and then back into the breadcrumbs a second time, sealing any thin spots.
- Place the breaded rolls seam side down on a plate, cover loosely, and refrigerate for at least 1 hour and up to overnight to set the crust.
- Pour the neutral oil into a deep heavy skillet or Dutch oven to a depth of about 2 inches and heat over medium-high to 340 F (170 C). Preheat the oven to 400 F (200 C).
- Carefully lower 2 chicken rolls into the hot oil, seam side down. Fry, turning gently with two spoons, for 6 to 7 minutes, until deeply golden brown on all sides.
- Transfer the fried rolls to a wire rack set over a sheet pan. Repeat with the remaining 2 rolls, returning the oil to 340 F between batches.
- Slide the sheet pan with all 4 rolls into the preheated oven and bake for 6 to 8 minutes, until the chicken registers 160 F (71 C) at its thickest point.
- Rest the chicken on the rack for 2 minutes only. Transfer to warm plates and serve immediately, instructing diners to cut into the center so the molten herb butter spills out onto the plate.
