1 teaspoon sugar
For the Meatloaf
1½ pounds (680 g) ground beef
½ pound (225 g) ground pork
1 cup breadcrumbs
2 large eggs
¼ cup milk
1 tablespoon Worcestershire sauce
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon dried thyme
Topping
1 cup shredded Swiss cheese
Equipment
Large skillet
Mixing bowl
9 × 5 inch loaf pan
Knife and cutting board
Measuring cups and spoons
Step-by-Step Instructions
1. Prepare the Oven
Preheat the oven to 350°F (175°C).
Lightly grease a 9×5 inch loaf pan or line it with parchment paper for easier removal.
2. Caramelize the Onions
Heat butter in a large skillet over medium heat.
Add:
sliced onions
sugar
Cook slowly, stirring occasionally.
Continue cooking for about 20 minutes until the onions become:
deep golden brown
soft
sweet-smelling
Remove from heat and allow them to cool slightly.
Reserve about ¼ cup of the onions for topping.
3. Prepare the Meat Mixture
In a large mixing bowl combine:
ground beef
ground pork
breadcrumbs
eggs
milk
Worcestershire sauce
salt
black pepper
dried thyme
Mix gently with your hands or a spoon until just combined.
Do not overmix because it can make the meatloaf dense.
4. Add the Onions
Fold most of the caramelized onions into the meat mixture.
Mix lightly to distribute them evenly.
5. Shape the Meatloaf
Transfer the mixture into the prepared loaf pan.
Press gently to shape it into an even loaf.
Spread the reserved caramelized onions over the top.
6. First Bake
Place the loaf pan in the oven.
Bake for 45 minutes until the meatloaf is mostly cooked and lightly browned.
7. Add the Cheese
Remove the meatloaf from the oven.
Sprinkle shredded Swiss cheese evenly over the top.
Return it to the oven.
Bake an additional 15 minutes until:
the cheese melts
the top becomes lightly golden
internal temperature reaches 160°F (71°C).
8. Rest the Meatloaf
Remove from the oven and let it rest for 10 minutes before slicing.
This step helps the juices redistribute and keeps slices neat.
Serving Suggestions
Serve the meatloaf with classic comfort-food sides such as:
Creamy mashed potatoes
Roasted green beans or carrots
Simple green salad with vinaigrette
Warm crusty bread
Expert Cooking Tips
1. Caramelization is key
Properly browned onions create the signature French onion flavor. Cook them slowly for best results.
2. Use a meat blend
The combination of beef and pork creates a juicier meatloaf than beef alone.
3. Avoid overmixing
Overworking the meat can make the texture firm.
4. Check temperature
The safest internal temperature for ground meat dishes is 160°F (71°C).
5. Let it rest
Resting ensures clean slices and better texture.

Storage
