Ingredients
🥩 Meatloaf
| Ingredient | Amount |
| Ground beef (80/20) | 2 pounds (900 g) |
| Breadcrumbs | 1 cup |
| Whole milk | ½ cup |
| Large eggs | 2 |
| Worcestershire sauce | 2 tablespoons |
| Garlic, minced | 3 cloves |
| Onion powder | 1 teaspoon |
| Salt | 1½ teaspoons |
| Black pepper | 1 teaspoon |
| Fresh parsley, chopped | 2 tablespoons |
🧅 French Onion Topping
| Ingredient | Amount |
| Yellow onions, thinly sliced | 2 large |
| Butter | 2 tablespoons |
| Olive oil | 1 tablespoon |
| Beef broth | ½ cup |
| Fresh thyme | 1 teaspoon |
| Gruyère or Swiss cheese, sliced | 8 ounces (225 g) |
🌿 Garnish
| Ingredient | Amount |
| Fresh parsley, chopped | For garnish |
Step-by-Step Instructions
Preheat the oven to 375°F (190°C).
Heat the butter and olive oil in a large skillet over medium heat.
Add the sliced onions and cook for 25–30 minutes, stirring occasionally, until deeply golden and caramelized.
Stir in the beef broth and thyme, then simmer for 3 minutes. Set aside.
In a large bowl, combine the ground beef, breadcrumbs, milk, eggs, Worcestershire sauce, garlic, onion powder, salt, pepper, and parsley.
Mix gently until just combined.
Shape the mixture into a loaf and place it in a lightly greased baking dish or loaf pan.
Bake for 45 minutes.
Remove the meatloaf from the oven and spread the caramelized onions evenly over the top.
Arrange the Gruyère or Swiss cheese slices over the onions.
Return the meatloaf to the oven and bake for another 20–25 minutes, until the cheese is melted and bubbly and the internal temperature reaches 160°F (71°C).
Allow the meatloaf to rest for 10 minutes before slicing.
Garnish with fresh parsley and serve warm.
Best Tips
Use ground beef with a little fat, such as 80/20, to keep the meatloaf juicy and flavorful.
Caramelize the onions slowly over medium-low heat. Rushing this step prevents them from developing their signature sweet flavor.
Avoid overmixing the meat mixture, as this can make the meatloaf dense instead of tender.
Let the meatloaf rest before slicing so it holds together beautifully.
Best Ingredient Options
| Ingredient | Best Substitute |
| Gruyère cheese | Swiss, Provolone, or Mozzarella |
| Ground beef | Ground turkey or ground chicken |
| Breadcrumbs | Crushed crackers or panko |
| Whole milk | Half-and-half or heavy cream |
| Fresh thyme | Dried thyme or Italian seasoning |
Recipe Variations
Add sautéed mushrooms to the onion topping for an even richer French onion flavor.
Mix shredded cheddar into the meat mixture for an extra cheesy center.
Use a combination of ground beef and ground pork for a more tender and flavorful meatloaf.
Brush the meatloaf with a light layer of barbecue sauce before adding the onions for a sweet and smoky twist.
What to Serve With
Creamy mashed potatoes are the perfect side dish because they soak up the delicious onion juices and melted cheese.
Roasted carrots, green beans, or asparagus add freshness and balance to the rich meatloaf.
Buttered egg noodles or roasted baby potatoes also pair wonderfully with this hearty dinner.
Warm dinner rolls or crusty artisan bread complete the meal beautifully.
Make-Ahead Instructions
Prepare and shape the meatloaf up to 24 hours in advance.
Store it covered in the refrigerator and bake just before serving.
The caramelized onions can also be prepared a day ahead and refrigerated separately.
Storage
Store leftover meatloaf in an airtight container in the refrigerator for up to 4 days.
Reheating
Reheat slices in a 350°F (175°C) oven for 10–15 minutes, or microwave individual portions for 2–3 minutes until heated through.
Freezing
Wrap the cooked or uncooked meatloaf tightly in plastic wrap and aluminum foil.
Freeze for up to 3 months.
Thaw overnight in the refrigerator before baking or reheating.
Common Mistakes to Avoid
Using lean beef can result in a dry meatloaf with less flavor.
Skipping the resting time may cause the loaf to fall apart when sliced.
Cooking the onions too quickly prevents proper caramelization and reduces their sweetness.
Overbaking the meatloaf can dry it out, so use a meat thermometer for the best results.
