Ingredients You’ll Need
For the Caramelized Onions:
- 3–4 large sweet onions, sliced
- 4 tbsp salted butter
- 1 tbsp olive oil
- 1 tsp sea salt
- 1 tsp coarse black pepper
- 1 tsp granulated sugar
For the Meatloaf:
- 1 lb ground beef
- 1 cup Italian herb bread crumbs
- 1 cup milk
- 1 egg
- 1 oz packet French onion soup mix
- ½ cup cooking sherry
- ½ tsp Worcestershire sauce
For the Topping:
- 4 oz Swiss, Gruyère, or provolone cheese, sliced or shredded
- Fresh thyme sprigs, for garnish
How to Make It
1️⃣ Caramelize the Onions
- In a large skillet, heat butter and olive oil over medium heat.
- Add sliced onions, salt, pepper, and sugar.
- Cook for 15–20 minutes, stirring occasionally, until onions are golden and caramelized. Set aside.
2️⃣ Mix the Meatloaf
- In a large mixing bowl, combine ground beef, bread crumbs, milk, egg, soup mix, cooking sherry, and Worcestershire sauce.
- Mix until just combined—don’t overwork the meat.
3️⃣ Layer in the Crockpot
- Lightly grease the inside of your slow cooker.
- Add half the caramelized onions to the bottom.
- Form the meat mixture into a loaf and place on top of the onions.
- Layer the remaining onions over the meatloaf.
4️⃣ Slow Cook
- Cover and cook on low for 6–8 hours or high for 3–4 hours, until the meat reaches an internal temperature of 160°F (70°C).
5️⃣ Add the Cheese
- About 15 minutes before serving, top the meatloaf with Swiss cheese.
- Cover again and let the cheese melt to perfection.
6️⃣ Serve
- Carefully lift the meatloaf out of the crockpot.
- Slice and serve hot, garnished with thyme sprigs for a fragrant, finishing touch.
Tips for Success
- Use sweet onions like Vidalia for the best caramelization.
- Don’t skip the cooking sherry—it adds depth and brings out the French onion flavor.
- For easier cleanup, line the crockpot with parchment or a slow cooker liner.
- Let the meatloaf rest for 5 minutes before slicing to keep it juicy.
