Preheat oven to 400 degrees F. Line large baking sheet with parchment paper and lightly spray with cooking spray. Set aside.
In a small bowl, add oats and milk. Stir and set aside to soak for 10 minutes while you are getting other ingredients ready.
In a large bowl, add ground turkey, eggs, onion, garlic, soaked oats, balsamic vinegar, oregano, salt and pepper. Using your hands mix just until combined. Don’t over mix or meatloaf will turn out tough.
Transfer mixture on previously prepared baking sheet and form into a loaf shape. Brush ketchup on top.
Bake for 45 minutes or or until cooked through. Meatloaf is ready when internal temperature is 160 degrees but I recommend not insert it in the center as juices run out. Instead go by cook time and adjust next time, if necessary.
Remove from the oven and let rest for 5-10 minutes. Garnish with parsley and cut into 8-10 slices. Serve hot with mashed potatoes and steamed green beans or broccoli.

Notes
Store: Refrigerate in an airtight container for up to 5 days.
Freeze: You can freeze cooked, cooled and sliced meatloaf in an airtight container for up to 3 months. Thaw in the refrigerator overnight.
Reheat: Reheat in the microwave or simmer in a covered pot with a splash of water. I do not like to warm up meatloaf in the oven because it dries out.
Recipe updated August 2025. Only change is I doubled all ingredients to make a larger loaf and used tiny but more oats. You can cut the recipe in 1/2 and bake for same amount of time in a loaf pan. Or bake 4 mini meatloaves for 35 minutes.
