Stir together the ground turkey, egg, panko, salt, 1 teaspoon of garlic, and ¼ teaspoon of pepper in a medium bowl until the ingredients are evenly combined. Shape mixture into 12 (about 1 ½-inch) meatballs; transfer to a parchment paper–lined baking sheet. Cover and refrigerate until ready to cook. (Here I’d go to step four.)
Cook the bacon in a large skillet over medium-high heat, stirring often, until it is crisp and rendered, about 8 minutes. Transfer bacon to a paper towel–lined plate using a slotted spoon. Reserve ¼ cup of drippings in the skillet; discard the remaining drippings, or reserve them for another use.
Return skillet with drippings to medium-high. Cook the meatballs, turning occasionally, until they are browned on all sides, about 6 minutes. Transfer meatballs to a plate and set aside. (Skip this step)
Very flavorful and easy. I followed the recipe, except I baked the meatballs at 375 for 15 minutes to make it even easier with less mess. I would use the meatball recipe alone to pair with any sauce. I forgot how tender and delicious turkey meatballs are!
Add mushrooms to the skillet with drippings, and cook over medium-high heat, undisturbed, until browned on one side, about 3 minutes. Stir and cook for 2 more minutes. Add the onion, 2 tablespoons of broth, and the remaining 2 teaspoons of garlic. Cook, scraping up browned bits from the bottom of the skillet, until onion is just tender, about 3 minutes. Add flour; cook, stirring constantly, for 1 minute. Add the wine, mustard, thyme, and the remaining ½ cup of broth; bring to a boil over medium-high heat.
Add the meatballs and half of the reserved bacon to the skillet; simmer over medium-low heat, turning the meatballs often, until a thermometer inserted into the meatballs registers 165°F and the sauce has thickened, 8 to 10 minutes. Stir in the cream and the remaining ¼ teaspoon of pepper. Season to taste with salt.
Cook the tagliatelle according to the package instructions. Serve the meatballs and sauce on top of the pasta, or serve pasta on the side. However, you prefer. Sprinkle with bacon, and garnish with additional thyme leaves.
