Make Meatballs: Place 3 slices white bread and 1/3 cup of creamer in a large bowl; let sit for 5-10 minutes. Use a fork to mash up the soaked bread and add 1 pound ground beef, 1/2 pound ground pork, 1 egg, 1 teaspoon onion powder, 1/2 teaspoon garlic powder, 1/4 teaspoon ground nutmeg, 1 teaspoon kosher salt and 1/2 teaspoon ground black pepper to the bowl. Mix to fully combine. Remove one tablespoon of the meat mixture at a time and roll into a meatball (highly recommend using a small cookie scoop). Continue this process with the rest of the meat mixture. Place meatballs in a single layer in an oven-safe cast iron skillet or braising pan.
Bake: Move the entire skillet to the oven and bake, uncovered, for 22-24 minutes or until cooked through. Use a slotted spoon to remove the cooked meatballs from the hot pan and set aside. Drain remaining grease, leaving about 1-2 tablespoons in the bottom.
Make Gravy: Bring large skillet to a medium-high heat and add 4 tablespoons butter to melt. Whisk in 6 tablespoons all-purpose flour to create a roux. Gradually pour in 2 1/4 cups beef broth, whisking continuously, until it is fully incorporated. Continue this process by pouring in the 1/3 cup of creamer, whisking continuously. Let simmer and thicken a bit, if needed to reach your desired consistency. Whisk in 2 tablespoons sour cream and 1/2 teaspoon kosher salt right before adding the meatballs back to the pan.
Combine: Add the meatballs back into the pan and toss in the cream sauce.
Serve: Recommend serving over mashed potatoes with or without a side of lingonberry jam.
