Make the Roulades the following day.
-
In a small bowl combine the breadcrumbs, sage, fennel pollen and minced garlic. Stir to combine.
-
Remove the turkey breasts from the brine and pick off any spices. Pat each breast dry.
-
Place a large piece of plastic wrap down on your work surface and place one breast, skin side down on top of the plastic wrap. Cover the turkey with another piece of plastic wrap. Do the same for the remaining turkey breast.
-
Use a meat mallet or the underside of a heavy-duty skillet, and pound each turkey breast to an even ½ inch (1 cm) thick, and approximately 9 x 10 inch (23 x 24 cm) rectangle. It won't be exactly like a rectangle, but it will be close. Use a downward and forward motion when pounding on the turkey breast, stopping every now and then to straighten out the plastic wrap on top of the breast. When you think you are close to done, stop and feel each flattened turkey with your hands for any uneven areas. Pound out these parts until each piece is flat with an even half inch width.
-
Remove the top piece of plastic wrap from each breast and evenly sprinkle Kosher salt over surface, about 1/4 tsp each breast. Add a few rounds of freshly ground black pepper over each breast.
-
Sprinkle the breadcrumb and herb mixture over each turkey breast, leaving a ½ inch (1 cm) boarder around the perimeter of each turkey breast. Sprinkle the grated cheese over the breadcrumbs and herbs. Make sure you have a nice even layer spread over the turkey's surface.
-
Fold inward a half-inch boarder along the long sides of each rectangular turkey piece. This will enclose the bread crumbs and cheese so they don't spill out when you are rolling it up and while cooking.
-
Start at the short end and roll up each turkey breast, keeping the folded edges inside the roulade. Use the plastic wrap to guide the turkey into place. Set aside.
-
Preheat the oven to 425°F / 220°C / Gas Mark 7 and place the rack in the middle position.
-
Lay a piece of plastic wrap lengthwise on a work surface. Arrange the bacon slices lengthwise across the middle of the plastic wrap. Overlap each piece of bacon, about 1/3 of the way over each piece lengthwise. Make sure there are no gaps. The bacon should line up across the middle of the plastic wrap to equal the length of each roulade. About 8-10 slices of bacon per turkey roulade.
-
Lay a turkey roulade across the middle of the bacon slices, so that the bacon strips run perpendicular to the turkey roulade. Lift the top side of plastic wrap with the bacon, up and over one side of the turkey. Peel away the plastic wrap while holding the bacon in place. The bacon slices should lay over half the width of the turkey roulade meeting close to the seam. Repeat with the other side. If the bacon ends do not meet, stretch them until they completely cover the turkey around its girth. Secure the bacon to the turkey with toothpicks. Set aside and repeat with the other turkey roulade.
-
Place a medium flameproof roasting pan on a burner set at medium-high heat. Add the extra virgin olive oil and heat until shimmering.
-
Add the roulades top side down into the roasting pan and sear the bacon for 4 minutes. The bacon will begin to brown. Turn each roulade over on its' side and sear for one minute. Repeat for the remaining sides, ending with the top side up.
-
Place the roasting pan in the oven and bake until an instant read thermometer registers 165°F / 74°C at the thickest part of each roulade, about 35 minutes.
-
Place each roulade on a cutting board and let the turkey rest for 10 minutes and up to an hour.
