How to Make Slow Cooker Stuffed Pepper Meatloaf

Prepare the crockpot: Lightly grease the black ceramic insert with a drizzle of olive oil. Place two long strips of parchment paper across the bottom, ensuring enough overhang for easy lifting after cooking.
Prepare the vegetables: Finely dice the green and red bell peppers, chop the onion, and mince the garlic. Keep the pieces small for even distribution.
Prepare the meatloaf mixture: In a large mixing bowl, combine the lean ground beef, diced bell peppers, onion, garlic, eggs, breadcrumbs, milk, cooked rice, tomato sauce, Worcestershire sauce, Italian seasoning, smoked paprika, garlic powder, salt, and black pepper.
Mix gently: Combine all ingredients until evenly incorporated, being careful not to overmix. The key is to maintain a tender texture.
Shape the meatloaf: Form the mixture into a thick oval loaf about 9 inches long and 5 inches wide. Place it in the center of the prepared crockpot.
Prepare the glaze: In a small bowl, whisk together the ketchup, brown sugar, Worcestershire sauce, yellow mustard, and smoked paprika until smooth and well blended.
Glaze the meatloaf: Spread half of the tomato glaze over the top and sides of the meatloaf. Reserve the remaining glaze in the refrigerator for later.
Slow cook: Cover the crockpot and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the center of the meatloaf reaches an internal temperature of 160°F (71°C).
Add the remaining glaze: During the final 20–30 minutes of cooking, spread the remaining tomato glaze over the top of the meatloaf and continue cooking until heated through.
Rest the meatloaf: Turn off the slow cooker and let the meatloaf rest for 10–15 minutes, allowing flavors to meld and making slicing easier.
Finish the dish: Lift the meatloaf using the parchment strips, remove the parchment, and slice it into thick portions. Arrange the slices slightly overlapping inside the crockpot for a beautiful presentation.
Garnish and serve: Sprinkle with freshly chopped parsley just before serving to add a splash of color and freshness.

Optional: Serve with creamy mashed potatoes or a crisp side salad for a complete meal.
