Preheat the oven to medium heat. Line a baking tray with parchment paper for clean cooking and easy lifting later.

Combine ground beef, breadcrumbs, egg, milk, onion, garlic, salt, and pepper. Stir slowly until the mixture feels even.

Divide the mixture into small equal parts. Shape each part into a tiny loaf with rounded edges for smooth cooking.

Place all mini loaves on the lined tray. Leave space between each loaf so heat moves evenly during baking.

Mix BBQ sauce, ketchup, brown sugar, and olive oil in a small pan. Heat gently until smooth and shiny.

Brush a thin layer of glaze over each loaf. Keep the coating light so the meat can brown nicely.

Bake the mini meatloaves until firm and slightly golden. The kitchen fills with a sweet smoky aroma.

Remove the tray briefly and add more glaze. The extra layer adds sweetness and deep barbecue flavor.

Return the loaves to the oven again. Bake until the glaze turns glossy and sticky on every loaf.

Let the mini meatloaves rest for a short time. This helps the juices settle and keeps every bite tender.
