How to Make French Onion Meatloaf

Preheat Oven: Begin by setting your oven to 375°F (190°C) to create the ideal cooking environment for your meatloaf. This ensures a delicious, even cook throughout.
Prepare Onions: In a pan over medium heat, sauté the sliced onions in a bit of oil until they become golden brown and caramelized—about 15-20 minutes. This step brings out their natural sweetness, essential to the French onion flavor.
Mix Ingredients: In a large bowl, combine the ground beef, caramelized onions, shredded cheese, breadcrumbs (or almond flour), eggs, and milk (or broth). Gently mix until just combined; be careful not to overwork the mixture to maintain tenderness.
Shape the Loaf: Form the mixture into a loaf shape and place it in a baking dish or on a lined baking sheet. Make sure it’s evenly shaped for consistent cooking.
Bake: Slide the meatloaf into the oven and bake it for 50-60 minutes or until the internal temperature reaches 160°F (70°C). A nice golden crust should form on the outside.
Rest: Once done, take the meatloaf out of the oven and let it rest for 10 minutes before slicing. This allows the juices to redistribute, ensuring a moist and flavorful meatloaf.

Optional: Garnish each slice with extra melted cheese for an indulgent touch.

French Onion Meatloaf Recipe FAQs

How do I select the best onions for caramelizing?
Choose yellow or sweet onions as they have the perfect balance of sweetness and flavor for caramelizing. Look for firm, smooth-skinned onions without any dark spots or blemishes. Fresh onions yield the best results, providing that rich, sweet profile essential for your French Onion Meatloaf.

What is the best way to store leftovers?
Allow your French Onion Meatloaf to cool completely before storing it in an airtight container. It can stay fresh in the refrigerator for up to 3 days. Place it in a single layer to prevent sogginess, and consider adding a piece of parchment paper between layers if you have more to stack.

Can I freeze French Onion Meatloaf, and how?
Absolutely! To freeze, wrap your uncooked French Onion Meatloaf tightly in plastic wrap, followed by a layer of foil to protect it from freezer burn. This way, it can stay fresh for up to 3 months. When you’re ready to cook it, simply thaw it in the refrigerator overnight before baking.

What should I do if my meatloaf falls apart when slicing?
If your meatloaf crumbles, it might be due to under-binding ingredients. Make sure to use enough eggs and breadcrumbs to hold it together. Also, allow the meatloaf to rest for about 10 minutes after baking before slicing. This lets the juices redistribute and helps keep the loaf intact.

Are there any adjustments for dietary restrictions?
Of course! You can easily make French Onion Meatloaf gluten-free by substituting regular breadcrumbs with almond flour or gluten-free breadcrumbs. Additionally, if you’re watching your fat intake, opt for lean ground beef or even ground turkey. Always check ingredient labels carefully for any hidden allergens.

Can I use different types of cheese?
Absolutely! While Gruyère or Swiss are the classic choices that give a lovely melt and flavor, feel free to experiment with other cheeses like cheddar or mozzarella. Just keep in mind that the flavor profile will vary—sharp cheeses add a tangy bite, while milder options will provide a creamier texture.
