Breadcrumbs

Panko can be used for a lighter texture.

Worcestershire sauce

It’s what makes the meatloaf taste rich and savory.

Ketchup (or BBQ sauce)

Step-by-Step Instructions

Prepare the onions first
Heat a skillet over medium heat and add a bit of oil.
Sauté chopped onions for 10–12 minutes until caramelized and soft.

Mix the meatloaf ingredients
In a large bowl, combine ground beef, eggs, breadcrumbs, French onion soup mix, Worcestershire sauce, salt, and pepper.
Add the caramelized onions and mix gently until evenly combined.

Shape the meatloaf
Form the mixture into a loaf shape that fits your crockpot.
Press it gently so it holds together but isn’t too compact.

Place in the crockpot
Lightly grease the crockpot insert, then place the meatloaf inside.
Cover and cook on low for 6–7 hours or high for 3–4 hours.

Add the glaze
About 30 minutes before it’s done, spread ketchup or BBQ sauce on top.
Let it cook uncovered to allow the glaze to set.

Check doneness
Use a meat thermometer to ensure the internal temperature reaches 160°F (71°C).
Let it rest for 10 minutes before slicing.
