Prep the oven and pan: Heat oven to 400°F (200°C). Lightly oil a sheet pan or line with parchment.
You can also use a muffin tin for tidy portions.
Soak the breadcrumbs: In a large bowl, mix breadcrumbs and milk. Let sit 2–3 minutes until the crumbs absorb the liquid. This keeps the meatloaf tender.
Add the flavor base: Stir in the egg, onion, garlic, 1/3 cup ketchup, Worcestershire, mustard, salt, pepper, paprika, and parsley.
Mix in the meat: Add ground beef and pork (or turkey).
Gently mix with your hands or a fork until just combined. Do not overmix or the mini loaves can turn dense.
Shape the minis: Divide into 8 even portions. Form small oval loaves (about the size of a large egg, slightly flattened) and place on the pan, leaving space between.
Top with sauce: Brush a thin layer of ketchup over each loaf for a glossy glaze. You can mix in a little brown sugar and vinegar if you like it tangier.
Bake: Cook 18–22 minutes, until the centers reach 160°F (71°C).
If using turkey, aim for 165°F (74°C). They should be browned with a slight glaze.
Rest and serve: Let them sit 5 minutes to reabsorb juices. Serve with mashed potatoes, roasted veggies, or a simple salad.
