How to Make French Onion Meatloaf
Step 1: Caramelize the Onions
Caramelizing sliced onions is key to bringing out their natural sweetness.
1. Heat olive oil in a skillet over medium heat.
2. Add thinly sliced onions.
3. Cook for about 20-25 minutes until they turn golden brown, stirring occasionally to prevent burning.
Step 2: Prepare the Meat Mixture
Combine all ingredients for a flavorful meatloaf.
1. In a mixing bowl, combine ground beef (or turkey), breadcrumbs, shredded cheese, egg, garlic powder, thyme, salt, pepper, and cooled caramelized onions.
2. Mix gently until just combined—be careful not to overmix.
Step 3: Shape the Meatloaf
Forming your meat mixture into a loaf shape helps with even cooking.
1. Transfer the mixture onto a lined baking sheet or into a loaf pan.
2. Shape it into a loaf approximately 8 inches long.
Step 4: Bake the Meatloaf
Now it’s time to bring everything together in the oven.
1. Preheat your oven to 375°F (190°C).
2. Place the meatloaf in the oven and bake for about 50-60 minutes.
3. Check that the internal temperature reaches 160°F (71°C) using a meat thermometer.
Step 5: Rest Before Slicing
Allowing the meatloaf to rest enhances its flavor and texture.
1. Let it rest for 5-10 minutes after removing from the oven.

Common Mistakes to Avoid
When making French Onion Meatloaf, it’s easy to overlook some details. Here are common mistakes and how to avoid them.
- Skipping the caramelization: Failing to properly caramelize the onions can lead to a lack of flavor. Spend extra time cooking them until they are golden brown and sweet.
- Overmixing the meat: Mixing the ingredients too much can result in a tough meatloaf. Combine everything gently until just mixed for a tender texture.
- Not measuring ingredients: Eye-balling ingredients, especially spices, can throw off the flavor balance. Use measuring cups and spoons for accuracy.
- Ignoring resting time: Cutting into the meatloaf immediately after baking can cause it to fall apart. Let it rest for 5-10 minutes to allow the juices to redistribute.
- Using stale breadcrumbs: Old breadcrumbs can affect the texture and taste of your meatloaf. Always use fresh or properly stored breadcrumbs for best results.
