- 1/2 teaspoon black pepper
- 6 ounces Gruyère cheese, shredded
- 1/4 cup beef stock

Step-by-Step Directions
- In a large skillet, melt butter over medium-low heat. Add sliced onions and sauté for 30-35 minutes. Stir occasionally until they are deeply caramelized. Deglaze the pan with balsamic vinegar and let cool.
- Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
- In a mixing bowl, combine beef, breadcrumbs, and milk. Add the egg, Worcestershire, thyme, salt, and pepper. Mix in half of the caramelized onions by hand.
- Place half the meat on the baking sheet. Shape it into a 9×5-inch rectangle.
- Layer remaining onions and Gruyère over the center. Leave a 1-inch border on all sides.
- Place the remaining meat mixture on top. Pinch the edges firmly to seal the loaf.
- Whisk beef stock and brown sugar together. Brush half of this glaze over the loaf.
- Bake for 55 minutes total. Brush with more glaze after 30 minutes. Ensure the internal temperature reaches 160°F (71°C).
- Rest the meatloaf for 10 minutes before slicing. This keeps the cheese from running out.
How to Serve It

Quick Questions
Can I make the onions ahead of time?
Yes, you can cook them a day early. Store them in the fridge until you’re ready. This saves you 30 minutes at dinner time.
What if I don’t have panko?
Standard breadcrumbs or crushed crackers work well too. They help hold the moisture inside the meat. Your loaf will still be perfectly juicy and delicious.
I hope your family loves this cozy meal as much as mine does. It really is the ultimate comfort food for a chilly night. Give it a try and enjoy every cheesy bite!
