Step-by-Step Preparation (Detailed)
Step 1: Prepare the Meatball Mixture
In a large bowl, combine ground beef, breadcrumbs, egg, milk, chopped onion, garlic, Worcestershire sauce, salt, and pepper.
Mix gently until just combined. Avoid overmixing — this keeps the meatballs tender instead of dense.
Pro Tip: Wet your hands slightly before mixing to prevent sticking.
Step 2: Shape the Meatballs
Roll the mixture into evenly sized meatballs, about 1–1.5 inches in diameter (roughly 30–35 g each).
Place them on a tray or plate as you go.
Step 3: (Optional) Brown the Meatballs
For extra flavor, lightly brown the meatballs in a pan over medium heat for 2–3 minutes per side.
This step adds a deeper, richer taste but can be skipped if you’re short on time.
Step 4: Prepare the Gravy
In the slow cooker, whisk together:
- Beef broth
- Onion soup mix
- Ketchup
- Worcestershire sauce
Mix until smooth.
Step 5: Add Meatballs to Slow Cooker
Gently place the meatballs into the gravy mixture, ensuring they are mostly submerged.
Step 6: Slow Cook to Perfection
- Low setting: 6–7 hours
- High setting: 3–4 hours
The meatballs should be tender, fully cooked, and infused with flavor.
Step 7: Thicken the Gravy
In the last 20–30 minutes, mix cornstarch with water to create a slurry.
Stir it into the slow cooker and let the gravy thicken.
Texture Cue: The gravy should coat the back of a spoon smoothly.
