French Onion Meatloaf Ingredients

For the Meatloaf
• Ground Beef – Provides rich, hearty flavor and structure; consider using ground turkey or chicken for a leaner option.
• Breadcrumbs – Acts as a binder to keep the meatloaf tender and moist; opt for gluten-free breadcrumbs to enjoy a gluten-free adaptation.
• Milk – Ensures a moist texture by hydrating the breadcrumbs; non-dairy milk can be used for a dairy-free version.
• Onions – Caramelized for sweetness and depth of flavor, they are integral to the recipe’s profile; remember to cook slowly to achieve the best results.
• Garlic – Adds aromatic depth; finely mince for even distribution in the meat mixture.
• Worcestershire Sauce – Enhances umami flavor, complementing the richness of the beef.
• Dijon Mustard – Provides a tangy note that balances the dish’s sweetness perfectly.

• Salt & Black Pepper – Elevates the overall flavor; adjust according to taste preferences.

For the Cheese Topping
• Gruyère or Swiss Cheese – Melts beautifully over the meatloaf, delivering creamy texture and nutty flavor; cheddar works well as an alternative if you can’t find Gruyère.

Step‑by‑Step Instructions for French Onion Meatloaf

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This is an important first step to ensure your French Onion Meatloaf bakes evenly. While the oven warms up, gather all your ingredients and equipment, such as a large mixing bowl and a greased baking dish ready for the meaty delight.

Step 2: Caramelize the Onions
In a skillet over medium heat, add two large, thinly sliced onions with a tablespoon of butter. Sauté them for 20-25 minutes, stirring occasionally, until they turn golden brown and become sweetly aromatic. Once caramelized, deglaze the pan with 1/4 cup of beef broth, mixing well, then allow the onions to cool.

Step 3: Prepare the Meatloaf Mixture
In a large mixing bowl, combine the ground beef, breadcrumbs, milk, minced garlic, and a beaten egg along with Worcestershire sauce, Dijon mustard, thyme, salt, and pepper. Gently mix the ingredients with your hands or a spatula, ensuring a well-combined, moist mixture without overworking it, which can lead to a tough meatloaf.

Step 4: Incorporate the Onions and Cheese
Carefully fold the cooled caramelized onions into the meat mixture, followed by half of the shredded Gruyère cheese. This infuses the meatloaf with a rich flavor and adds a delightful gooeyness that mimics the essence of French onion soup. Make sure the ingredients are evenly distributed but remain tender.

Step 5: Shape and Bake
Transfer your meatloaf mixture into the prepared baking dish, shaping it into a loaf roughly 2 inches high. Place it in the preheated oven and bake for about 1 hour, or until the internal temperature reaches 160°F (70°C). Keep an eye on it; golden brown edges signify that your French Onion Meatloaf is on the right track.

Step 6: Add the Cheese Topping
Once baked, remove the meatloaf from the oven and sprinkle the remaining Gruyère cheese generously over the top. Return it to the oven for an additional 5-10 minutes, allowing the cheese to melt and form a bubbly, decadent layer atop your meatloaf, enhancing its gourmet appeal.

Step 7: Rest and Serve
After baking, it’s crucial to let the French Onion Meatloaf rest for about 10 minutes. This resting period allows the juices to redistribute, ensuring each slice is juicy and holds its shape beautifully when served. Slice and enjoy the savory combination of flavors that make this dish a feast for the senses!

Expert Tips for French Onion Meatloaf

Use a Meat Thermometer: Ensure your French Onion Meatloaf reaches an internal temperature of 160°F (70°C) for safe consumption and optimal juiciness.
Avoid Overmixing: Gently combine the meat mixture to prevent a dense, tough meatloaf. Overmixing can ruin the tender texture.
Perfect Onions: Cook the onions slowly over medium heat to achieve an even caramelization; this adds the essential rich flavor to your meatloaf.
Let It Rest: Allow the meatloaf to rest for 10 minutes post-baking. This helps retain moisture and makes slicing easier without it falling apart.
Customize Your Cheese: While Gruyère is wonderful, experimenting with different cheeses like cheddar or mozzarella can create exciting flavor variations!

Make Ahead Options

French Onion Meatloaf is perfect for meal prep enthusiasts! You can prepare the meat mixture, including the caramelized onions and cheese, up to 24 hours in advance. Simply follow the steps to combine the ground beef, breadcrumbs, milk, and spices, then fold in the cooled onions and half the cheese. Before serving, shape the mixture into a loaf and bake as directed. If you prefer, you can also bake the meatloaf completely, allow it to cool, and then refrigerate it for up to 3 days. When you’re ready to enjoy, simply reheat it in the oven at 300°F (150°C) until warmed through, ensuring it remains just as delicious and juicy as when freshly baked!
