Preheat your oven to 375°F. In a large bowl, combine the 4 cups of stuffing mix with the 18 fl oz of heated turkey stock, stirring until the bread is evenly moistened and begins to soften (about 2-3 minutes). In a separate skillet, melt the 7 tablespoons of butter over medium heat and add the diced onion, celery, and minced garlic. Sauté for 5-7 minutes, stirring occasionally, until the vegetables are completely softened and fragrant. Season this mixture with the Bell's seasoning while cooking. Once the vegetables are tender, set them aside to cool slightly—this cooling step is important because you don't want to cook the eggs when you mix them in.

Pulse or grind the remaining 1 cup of stuffing mix into fine crumbs using a food processor or by hand with a fork—this will create a better texture binder than whole pieces. In a large mixing bowl, combine the lightly beaten eggs, ground turkey, salt, black pepper, and fresh parsley. Add the softened stuffing mixture from Step 1 to the turkey mixture, followed by the cooled sautéed vegetables and the stuffing crumbs. Using your hands, gently fold everything together just until combined—don't overmix, as this can make the meatloaf dense and tough. I like to do a quick seasoning check by cooking a small spoonful of the mixture in a hot skillet for 1-2 minutes to taste before shaping the full loaf.

Lightly grease a large baking sheet or a 9x13-inch baking dish. Transfer the meatloaf mixture onto the prepared surface and, using wet hands (which prevents sticking), gently shape it into a compact log or oval loaf about 2-3 inches tall. Place it in the preheated 375°F oven and bake for 55-60 minutes, until the internal temperature reaches 155°F when measured with an instant-read thermometer inserted into the thickest part of the loaf. Remove the meatloaf from the oven and cover it loosely with aluminum foil, then let it rest for 15 minutes—this allows the juices to redistribute and keeps the meat moist when you slice it.

While the meatloaf rests, bring the 16 fl oz of turkey stock to a gentle boil in a saucepan over medium-high heat. In a separate skillet over medium heat, melt the 4 tablespoons of butter and whisk in the all-purpose flour, stirring constantly for 2-3 minutes until the mixture (called a roux) is light golden and smells nutty—this cooking step removes the raw flour taste. Slowly pour the hot stock into the roux while whisking continuously to prevent lumps from forming. Once fully incorporated, reduce the heat to low and stir in the browning sauce, then simmer gently for 3 minutes to deepen the color and thicken slightly.

Remove the foil from the rested meatloaf and slice it into thick, even pieces using a sharp knife or serrated blade. Arrange the slices on a serving platter or individual plates. Pour the warm gravy from Step 4 over or alongside the meatloaf slices, and serve with cranberry sauce on the side for a classic, comforting presentation.
