- Make the meatloaf: Preheat oven to 350 degrees. In large bowl, combine all meatloaf ingredients except ground chuck, and mix thoroughly. Add ground chuck and, using your hands, mix just to combine. (Overworking the meat will lead to a dense loaf.)
- Shape mixture into a rectangular loaf. Smooth, using a spatula dipped in water. Spray a baking sheet with lip with nonstick cooking spray and place loaf in middle. Bake for 50 minutes, or until meat thermometer registers 165 degrees.
- While loaf is baking, make tomato creole sauce: To a small saucepan, add oil, onion, celery, garlic, and a pinch of salt. Sauté on medium heat for 5 to 10 minutes, until soft. Add remaining ingredients and cook for about 10 more minutes, stirring vigorously so the sauce doesn’t burn.
- After removing meatloaf from oven, let rest 10 minutes before slicing. Serve with tomato creole sauce ladled over each serving.
