Prep: Preheat the oven to 375 degrees F. (See: Notes for stove top/sear option)
Meatball Mixture: Put the bread slices and creamer in a large bowl. Let it soak for 5-10 minutes. Use a fork to break the bread apart and then add the rest of the meatball ingredients to the bowl. Mix everything to fully combine.
Form Meatballs: Use a cookie scoop or ice cream scoop to form 1 1/2 tablespoon meatballs and roll between your hands. Continue this process with the rest of the meatball mixture and place the meatballs in a single layer in a large cast iron skillet or braiser that can go in the oven.
Bake: Move the large skillet to the preheated oven to bake for 22-24 minutes or until the internal temperature of the meatballs reaches 165 degrees F (use a meat thermometer).
Optional Serving Suggestions: While the meatballs bake, it is the perfect time to make the stuffing, mashed potatoes, or any other items that you plan to serve with the meatballs and gravy. Or make these when you have lots of holiday leftovers to warm up.
Make Gravy: Once the meatballs are fully cooked, carefully remove them from the oven and use a slotted spoon to remove meatballs from the hot skillet - set aside. Do NOT drain the grease. Bring the large skillet to a medium-high heat and add butter to melt. Whisk in the flour to create a paste or roux. Gradually pour in the turkey broth, a half cup at a time, whisking continuously to make a thick and creamy gravy. Whisk in the salt and pepper, taste and make any desired adjustments. If you prefer a thicker gravy, let it simmer for a little bit and if you prefer a thinner gravy, add a little more broth.
Combine: Add the cooked meatballs back to the hot pan and toss in the gravy to fully coat.
Serve: Highly recommend serving these meatballs in a bowl with stuffing, mashed potatoes, and cranberry sauce with plenty of gravy on top!
Notes
Stove Top Variation: If you prefer a sear on your meatballs, feel free to skip the oven option and cook them on the stove top instead. Take a large cast iron skillet and add just enough olive oil to thinly coat the pan. In batches, sear the meatballs on medium-high heat and then let cook on medium heat until cooked through (approx. 10-15 minutes). Internal temp should reach 165 degrees F. Then remove the meatballs from the skillet and take a little extra broth to deglaze the pan and then continue making the gravy. The color of the gravy with the stove-top version might be a little darker than if you bake the meatballs.
Holiday Leftovers: If you have a lot of leftovers from a Thanksgiving dinner or Christmas dinner, like stuffing, mashed potatoes, & cranberry sauce, we highly recommend making these Thanksgiving Meatballs for dinner and serving in a bowl with all those delicious side dishes!
