Ingredients Notes

The magic of this French Onion Meatloaf lies in its carefully selected ingredients, each contributing to the dish's rich, savory flavor. Let’s break them down.
The ground beef forms the heart of the meatloaf. Opt for 80/20 ground beef for the perfect balance of flavor and moisture. You can mix in a bit of ground pork if desired for an extra boost of juiciness.
Caramelized onions are the star of the show. Slow-cooked to golden perfection, they add sweetness and depth. Be patient with this step; the flavor payoff is worth it.
A blend of breadcrumbs and milk acts as a binder, keeping the meatloaf tender and moist. This combination prevents the meatloaf from becoming dense or dry.
Gruyère cheese is the ideal topping. Its nutty, creamy profile melts beautifully and pairs wonderfully with the onions. If Gruyère isn’t available, Swiss cheese works as an excellent substitute.
The glaze, made from a mix of beef broth and Worcestershire sauce, adds a savory finishing touch. It seeps into the meatloaf as it bakes, enhancing its flavor and moisture.
You’ll also need a standard loaf pan for baking. If you don’t have one, you can shape the meatloaf free-form on a baking sheet, but the pan ensures a consistent shape and even cooking.
How To Make This French Onion Meatloaf

Creating this delicious meatloaf is easier than you think. With just a bit of prep and some hands-off baking time, you’ll have a show-stopping dish on your table in no time.
Start by caramelizing your onions. Heat a skillet over medium-low heat, add butter, and let it melt. Toss in thinly sliced onions and cook slowly, stirring occasionally, until they’re golden brown and fragrant. This process takes about 20-25 minutes, but the resulting flavor is unmatched.
While the onions cook, prepare the meat mixture. In a large bowl, combine ground beef, breadcrumbs soaked in milk, an egg, minced garlic, and a splash of Worcestershire sauce. Mix gently to keep the meatloaf light and tender.
Once the onions are ready, let them cool slightly before folding half of them into the meat mixture. Save the other half for topping. Transfer the meat mixture to your loaf pan, pressing it down gently to create an even layer.
Top the meatloaf with the reserved caramelized onions and a generous layer of shredded Gruyère cheese. Bake at 375°F (190°C) for 45-50 minutes, or until the internal temperature reaches 160°F (71°C).
Let the meatloaf rest for 10 minutes before slicing. This allows the juices to redistribute, ensuring every slice is moist and flavorful.
Storage Options
French Onion Meatloaf is as easy to store as it is to make, making it perfect for meal prep or leftovers.
To refrigerate, place any leftovers in an airtight container and store them for up to 3 days. Reheat slices in the oven or microwave, covered, to prevent drying out.
For longer storage, freeze individual slices or the entire loaf. Wrap tightly in plastic wrap, then foil, and store in a freezer-safe bag for up to 3 months. Thaw in the refrigerator overnight before reheating.
Reheat frozen slices directly in the oven at 350°F (175°C) for 15-20 minutes or until warmed through. The flavors only deepen with time, so don’t worry about losing any of that deliciousness.
Variations and Substitutions
This recipe is incredibly versatile, allowing you to customize it to your taste and dietary needs.
- Swap the Gruyère cheese for cheddar or mozzarella if you prefer a different flavor profile.
- Add sautéed mushrooms or bell peppers to the meat mixture for extra texture and nutrition.
- Use ground turkey or chicken instead of beef for a leaner option. Be sure to adjust the cooking time as needed.
- For a gluten-free version, replace the breadcrumbs with gluten-free breadcrumbs or crushed rice crackers.
- If you like a touch of heat, mix in a pinch of red pepper flakes or a splash of hot sauce.
Don’t be afraid to get creative and make this dish your own. It’s hard to go wrong with such a flavorful base!
Whether you’re making it for a cozy family dinner or impressing guests with a gourmet twist, French Onion Meatloaf is sure to deliver every time. Give it a try, and watch it become a beloved staple in your kitchen!
