Ingredients
For the Meatloaf:
- 2 pounds ground beef (80/20 recommended for juiciness)
- 1 cup breadcrumbs
- 1/2 cup grated Parmesan cheese
- 1/4 cup milk
- 2 large eggs
- 1 tablespoon Worcestershire sauce
- 1 teaspoon salt
- 1/2 teaspoon black pepper
For the Buttered Onions and Topping:
- 2 large onions, thinly sliced
- 2 tablespoons butter
- 6–8 slices Swiss cheese
- Optional: fresh thyme for garnish
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a loaf pan or line a baking sheet with parchment paper if you prefer shaping the meatloaf by hand.
Step 2: Caramelize the Onions
In a large skillet over medium heat, melt the butter. Add the thinly sliced onions and cook slowly, stirring occasionally.
Let the onions cook for about 20 to 25 minutes, until they become soft, golden brown, and deeply caramelized. Cooking them slowly is essential to develop their natural sweetness and rich flavor.
If the onions begin to brown too quickly, lower the heat. You want them soft and golden, not burned.
Once caramelized, remove from heat and set aside.
Step 3: Prepare the Meatloaf Mixture
In a large mixing bowl, combine:
- Ground beef
- Breadcrumbs
- Grated Parmesan cheese
- Milk
- Eggs
- Worcestershire sauce
- Salt and black pepper
Mix gently with your hands or a spoon until just combined. Avoid overmixing, as this can make the meatloaf tough and dense.
For extra flavor, you may mix a small handful of the caramelized onions directly into the meat mixture.
Step 4: Shape the Meatloaf
Transfer the mixture into your prepared loaf pan and shape evenly. If using a baking sheet, form the mixture into a firm loaf shape.
Press gently to smooth the top without packing it too tightly.
Step 5: Bake the Meatloaf
Place the meatloaf in the preheated oven and bake for 40 to 45 minutes, or until the internal temperature reaches 160°F (71°C).
Step 6: Add the Onion and Cheese Topping
Remove the meatloaf from the oven. Spread the caramelized onions evenly over the top.
Layer the Swiss cheese slices over the onions, covering the surface completely.
Return the meatloaf to the oven and bake for an additional 10 to 15 minutes, or until the cheese is melted and bubbly.
For a slightly golden, restaurant-style finish, you can broil it for 1 to 2 minutes — but watch carefully to prevent burning.
Step 7: Let It Rest
Allow the meatloaf to rest for at least 10 minutes before slicing. This helps the juices redistribute and makes slicing easier.
Tips for the Best French Onion Meatloaf
- Use ground beef with some fat for maximum moisture.
- Do not skip caramelizing the onions — it makes all the difference.
- Let the meatloaf rest before cutting to keep it juicy.
- Add a splash of beef broth to the onions for extra richness.
- For extra cheesiness, mix shredded Swiss into the meat mixture.
Serving Suggestions
This flavorful meatloaf pairs perfectly with:
- Creamy mashed potatoes
- Roasted carrots or green beans
- Garlic bread
- Simple garden salad
The combination of savory beef, sweet onions, and melted cheese makes it a complete, satisfying main course.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days.
To reheat, warm slices in the oven at 325°F until heated through, or microwave gently. Add a splash of broth if needed to keep it moist.
This meatloaf also freezes well for up to 3 months when wrapped tightly.
