Step‑by‑Step Instructions for French Onion Meatloaf
Step 1: Caramelize the Onions
Begin by slicing the onions thinly, then place them in a large skillet over low heat. Add a bit of oil or butter and cook for 20-25 minutes, stirring occasionally, until they are beautifully golden and caramelized. This step adds a deep, rich sweetness to your French Onion Meatloaf, enhancing its overall flavor profile.
Step 2: Prepare the Meat Mixture
In a large mixing bowl, combine the ground beef, the caramelized onions you just made, eggs, breadcrumbs, and milk or broth. Sprinkle in your chosen seasonings, such as salt, pepper, and herbs. Mix gently with your hands until well combined, but don’t overwork the meat; you want to keep it tender for your meatloaf.
Step 3: Shape the Meatloaf
Once combined, shape the meat mixture into a loaf and place it in a greased baking dish. Ensure the loaf is even in thickness, as this will help it cook uniformly. If desired, you can use parchment paper for easier cleanup, making your preparation of the French Onion Meatloaf that much simpler.
Step 4: Add Cheese Topping
Generously sprinkle shredded cheese over the top of the formed meatloaf. This will create a deliciously cheesy crust as it bakes, taking your French Onion Meatloaf to the next level of comfort food delight. Press down gently to ensure the cheese sticks to the meat.
Step 5: Bake the Meatloaf
Preheat your oven to 375°F (190°C) while the cheese topping settles. Once heated, bake the meatloaf for 50-60 minutes. To check for doneness, use a meat thermometer; the internal temperature should reach 160°F (71°C), ensuring a safe and juicy meatloaf.
Step 6: Rest Before Slicing
After removing the meatloaf from the oven, let it rest for about 10 minutes. This allows the juices to redistribute throughout the French Onion Meatloaf, ensuring every slice is moist and flavorful. Use this time to set the table or prepare your favorite side dishes.
Step 7: Slice and Serve
Finally, slice the meatloaf into individual servings and plate them. Serve warm, perhaps with a sprinkle of fresh parsley to add a touch of color and brightness. This French Onion Meatloaf is sure to be a hit at the dinner table!

Expert Tips for French Onion Meatloaf
-
Onion Perfection: Caramelize slowly: Take your time with the onions to achieve that sweet, deep flavor—rushing will yield bitterness.
-
Keep it Tender: Don’t overmix: Gently combine ingredients without overworking the meat; a tender meatloaf is always more enjoyable!
-
Moisture Matters: Use broth: Opting for broth instead of milk can amplify the flavor in your French Onion Meatloaf, making it even more delicious.
-
Check for Doneness: Use a thermometer: Ensure the internal temperature reaches 160°F (71°C) for perfectly cooked meatloaf—nobody wants dry meat!
-
Resting is Key: Allow to rest: Letting the meatloaf sit for 10 minutes before slicing keeps it juicy and prevents crumbling.

French Onion Meatloaf Recipe FAQs
How do I select the best onions for caramelizing?
Absolutely! Look for onions that are firm and heavy for their size, with no dark spots or blemishes. Yellow onions work best for caramelizing, as they have the right balance of sweetness and flavor. Aim for medium to large-sized onions; you'll need about 2-3 to make 2 cups of caramelized onions.
How should I store leftovers of the French Onion Meatloaf?
Very simply! Once cooled, store sliced French Onion Meatloaf in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy, reheat slices in the microwave for a quick meal or use the oven at 350°F (175°C) to warm them, ensuring they remain deliciously juicy.
Can I freeze uncooked French Onion Meatloaf? How should I do that?
Yes, indeed! To freeze the uncooked French Onion Meatloaf, shape it into a loaf and wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can be safely frozen for up to 3 months. When you're ready to cook it, just thaw it overnight in the fridge before baking; this way, the meatloaf stays flavorful and moist during cooking!
What’s the best way to reheat leftover meatloaf?
For the best results, I recommend reheating leftovers in a preheated oven at 350°F (175°C) for about 15-20 minutes. This method allows the meatloaf to warm evenly while retaining its moisture. Alternatively, you can use the microwave, but do so on medium power for short intervals to avoid drying it out.
Are there any dietary considerations with this recipe?
Absolutely! If you or your guests have allergies, be mindful of the ingredients used. For instance, if you're gluten-sensitive, you can substitute breadcrumbs with gluten-free options, or even use ground oats. Always check the labels of the cheese to ensure they meet dietary restrictions. Also, keep in mind that cooked meatloaf should not be fed to pets, as some ingredients such as onions can be harmful to them.
