Step 1 – Caramelize The Onions
Preheat oven to 350°F. In a large skillet, melt butter over medium heat. Add thinly sliced onions and sugar, cooking and stirring occasionally until caramelized and golden brown, about 20 minutes.

Step 2 – Mix The Meat Mixture
In a large bowl, combine ground beef, ground pork, breadcrumbs, eggs, milk, Worcestershire sauce, salt, pepper, and thyme. Mix until just combined – don’t overmix!

Step 3 – Add Most Of The Onions
Fold most of the caramelized onions into the meat mixture, reserving a small portion to top the meatloaf later for that gorgeous presentation.

Step 4 – Shape And Top
Transfer the meat mixture to a loaf pan, pressing down gently to form an even loaf. Top with the reserved caramelized onions for beautiful golden color.

Step 5 – First Bake
Bake in the preheated oven for 45 minutes until the meatloaf is nearly cooked through and starting to brown on top.

Step 6 – Add Cheese And Finish
Remove from oven and sprinkle shredded Swiss cheese over the top. Return to oven and bake for an additional 15 minutes until cheese is melted and bubbly.

Step 7 – Rest And Serve
Let the meatloaf rest for 10 minutes before slicing – this helps it hold together perfectly and allows the juices to redistribute for the best texture.

Expert Tips

Master this gourmet meatloaf with these helpful tips for perfect results every time!

Take time with the onions – proper caramelization takes about 20 minutes. Don’t rush this step – it’s where all the amazing flavor comes from!

Don’t overmix the meat – mix just until ingredients are combined to keep the meatloaf tender and not tough.
Use the right meat ratio – the combination of beef and pork creates the perfect texture and flavor. Don’t substitute all beef.
Let it rest – the 10-minute resting period is crucial for easy slicing and the best texture.
Save some onions – reserving caramelized onions for the top creates beautiful presentation and extra flavor in every bite.
Check internal temperature – meatloaf should reach 160°F internally for food safety.
Line the pan – lining your loaf pan with parchment makes removal much easier.
Make ahead tip – can be assembled and refrigerated up to 24 hours before baking.
