Ingredients You’ll Need
Gathering simple, quality ingredients is the key to nailing this recipe. Each component plays an essential role in building layers of flavor, moisture, and texture that create the ultimate French Onion Meatloaf experience.
- 1 ½ pounds ground beef: Choose a mix with some fat for juiciness and flavor.
- 1 packet (1 oz) dry French onion soup mix: This seasoning blend is the heart of the dish, infusing it with rich onion and herb notes.
- ½ cup plain breadcrumbs: Helps bind the meat and keeps it tender without drying out.
- 2 large eggs: Acts as a binder to hold all the ingredients together perfectly.
- ½ cup milk: Adds moisture, keeping the meatloaf soft and succulent.
- 1 tablespoon Worcestershire sauce: Boosts umami and deepens the savory profile.
- 1 cup shredded mozzarella cheese: Melts beautifully inside, adding a gooey, cheesy surprise.
- 1 tablespoon ketchup (plus extra for topping): Adds a subtle sweetness and tang, enhancing the overall flavor.
- Salt and black pepper to taste: Essential for seasoning and bringing all the flavors together.
- Chopped fresh parsley (optional): For a fresh, vibrant garnish and a pop of color.
How to Make French Onion Meatloaf Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F (190°C) and lightly greasing a loaf pan. This sets the stage for even cooking and prevents sticking, making it easy to remove the meatloaf once done.
Step 2: Combine Ingredients
In a large mixing bowl, add the ground beef, dry French onion soup mix, breadcrumbs, eggs, milk, Worcestershire sauce, shredded mozzarella, ketchup, salt, and black pepper. Use your hands or a spoon to mix everything until just combined. The key is not to overmix, as that can make the meatloaf dense instead of tender and juicy.
Step 3: Shape and Top
Transfer the meat mixture into your prepared loaf pan, pressing it down and shaping it evenly. Once shaped, spread a thin layer of ketchup over the top. This glaze will caramelize during baking, adding a flavorful, slightly tangy crust.
Step 4: Bake to Perfection
Bake in your preheated oven for 50 to 60 minutes. The meatloaf is done when its internal temperature reaches 160°F (71°C). This ensures it’s safely cooked but still moist and tender. After removing it from the oven, let it rest for 10 minutes—this resting time allows juices to redistribute, making each slice juicy and flavorful.
How to Serve French Onion Meatloaf Recipe

Garnishes
A sprinkle of freshly chopped parsley adds a lovely burst of color and freshness that brightens the rich flavors of the meatloaf. You can also consider a light drizzle of extra ketchup or even a spoonful of caramelized onions for an extra special touch.
Side Dishes
This French Onion Meatloaf Recipe pairs beautifully with classic comfort sides. Think creamy mashed potatoes, roasted vegetables, or a simple green salad to balance the rich flavors. For a lighter option, steamed green beans or sautéed mushrooms work wonderfully too.
Creative Ways to Present
If you want to switch things up, slice the meatloaf and serve it open-faced on toasted bread with a slice of provolone or Swiss cheese melted on top. Or wrap leftover slices in a warm pita with lettuce and mustard for a tasty sandwich that’s perfect for lunch the next day.
Make Ahead and Storage
Storing Leftovers
Once cooled, wrap leftover meatloaf tightly in plastic wrap or store in an airtight container and refrigerate. It will keep well for up to 3-4 days, making it a great option for quick meals later in the week.
Freezing
You can freeze the meatloaf either whole or sliced. Wrap it tightly in plastic wrap and then foil or place in a freezer bag to prevent freezer burn. Frozen meatloaf will last up to 3 months without losing flavor or texture.
Reheating
To reheat, thaw meatloaf slices overnight in the refrigerator if frozen. Warm gently in the oven at 325°F (160°C) until heated through to avoid drying out, or microwave on a medium setting, covered, to retain moisture.
FAQs
Can I use different cheese in this French Onion Meatloaf Recipe?
Absolutely! Mozzarella is classic for its meltiness, but try Swiss or provolone for a slightly different flavor twist that complements the onion soup mix wonderfully.
Is there a gluten-free option for this recipe?
Yes, simply swap the plain breadcrumbs for gluten-free breadcrumbs to keep the meatloaf texture perfect without gluten.
How do I avoid a dry meatloaf?
Don’t overmix your ingredients and make sure to include milk and eggs, as they add moisture. Also, resting the meatloaf after baking helps keep it juicy when sliced.
Can I make this recipe with ground turkey or chicken?
You can, but keep in mind these leaner meats may result in a drier meatloaf. Consider adding a bit more moisture like extra milk or a tablespoon of olive oil to compensate.

Leftover French Onion Meatloaf makes fantastic sandwiches. Serve slices on your favorite bread with mustard, lettuce, and tomato for a comforting and delicious lunch option.
