How to Make Crockpot French Onion Meatloaf
Ingredients
- 2 large sweet onions, thinly sliced
- 2 tbsp salted butter
- 1 tbsp olive oil
- 1 tsp sea salt
- ½ tsp coarse black pepper
- 1 tsp granulated sugar
- 1 tbsp cooking sherry (optional)
- 1 ½ lbs ground beef (80/20)
- ½ cup Italian-style breadcrumbs
- ¼ cup whole milk
- 1 large egg
- 1 packet (1 oz) French onion soup mix
- 1 tbsp Worcestershire sauce
- Half of the caramelized onions (reserve the rest for topping)
- 6-8 slices Swiss, Gruyère, or provolone cheese
- Fresh thyme sprigs (for garnish)
Directions
Caramelize the Onions:
In a skillet, melt the butter and olive oil over medium heat. Add the thinly sliced onions, sea salt, black pepper, granulated sugar, and cooking sherry (if using). Cook the onions slowly, stirring occasionally, until they are soft and golden brown, about 15-20 minutes.
Prepare the Meatloaf:
In a large mixing bowl, combine the ground beef, breadcrumbs, milk, egg, French onion soup mix, Worcestershire sauce, and half of the caramelized onions. Mix until just combined, being careful not to overmix.
Slow Cook the Meatloaf:
Shape the meat mixture into a loaf and place it in the crockpot. Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the meatloaf is cooked through and reaches an internal temperature of 160°F (70°C).
Add the Cheese Topping:
About 15 minutes before the meatloaf is done, place the remaining caramelized onions on top, followed by the slices of cheese. Cover and cook until the cheese is melted and bubbly.
How to Serve Crockpot French Onion Meatloaf
This savory meatloaf is best served warm, straight out of the crockpot. Slice thickly and serve alongside creamy mashed potatoes, steamed vegetables, or a fresh side salad. For added flair, garnish with fresh thyme sprigs to elevate the presentation.
How to Store Crockpot French Onion Meatloaf
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. The meatloaf also freezes well; wrap it tightly in plastic wrap and aluminum foil, and it can be frozen for up to 3 months. When ready to eat, thaw it in the refrigerator overnight and reheat in the oven or microwave until heated through.
