This French Onion Meatloaf is a warm and hearty dish that beautifully mixes savory ground beef with the rich flavor of caramelized onions. It’s topped with a delicious glaze that gives it a tasty kick!
When I make this meatloaf, I love how the smell fills the kitchen—it’s the kind of comfort food that makes everyone excited for dinner! Pair it with mashed potatoes, and you’re all set for a cozy meal.
Key Ingredients & Substitutions
Yellow Onions: These are ideal for caramelizing due to their sweetness. If you need a substitute, you can use sweet onions like Vidalias or even red onions, though they may alter the color slightly.
Ground Beef: I recommend using 80/20 for the juiciest meatloaf. However, feel free to swap for ground turkey, chicken, or even a plant-based ground for a lighter option.
Swiss Cheese: This cheese melts beautifully and adds great flavor. If you’re looking for something different, try Gruyère, provolone, or even a sharp cheddar for a bolder taste.
Balsamic Vinegar: This adds depth to your caramelized onions. If you don’t have it, red wine vinegar or apple cider vinegar can work well too, just use a little less as they can be tangier.
How Do I Properly Caramelize Onions?
Caramelizing onions takes patience but yields great flavor. Below are steps to perfect this crucial part of the meatloaf.
- Start with a large skillet and set it on medium heat. Add olive oil and then the sliced onions, ensuring they’re evenly coated.
- Sprinkle sugar halfway through cooking. This helps the onions caramelize faster and enhances their sweetness.
- Cook for about 25-30 minutes, stirring occasionally. You want them to become golden brown and very soft.
- After caramelization, add balsamic vinegar and stir for an extra minute to incorporate the flavor.
Don’t rush! The longer you take to caramelize, the deeper the flavors will develop.

How Much Time Will You Need?
This delicious French Onion Meatloaf takes about 10 minutes for prep and 1 hour for baking, totaling approximately 1 hour and 10 minutes. Allow for an additional 10 minutes of resting time after it comes out of the oven. It’s easy and just right for any cozy dinner!
Step-by-Step Instructions:
1. Prepare the Onions:
Start by preheating your oven to 350°F (175°C). In a large skillet, heat the olive oil over medium heat. Add the thinly sliced onions. Cook them slowly, stirring occasionally for about 25-30 minutes, until they’re caramelized and golden brown. Halfway through, sprinkle in the sugar to help them caramelize better. Once beautifully caramelized, stir in the balsamic vinegar, cook for another minute, then remove from heat and set aside.
2. Mix the Meatloaf Ingredients:
In a large bowl, soak the breadcrumbs in milk for about 5 minutes until they’re softened. Then add the ground beef, egg, minced garlic, Worcestershire sauce, dried thyme, salt, and black pepper. Mix gently, using your hands or a spoon. Be careful not to overwork the mixture; just combine everything well.
3. Shape and Bake the Meatloaf:
Lightly grease a loaf pan, or line a baking sheet with parchment paper. Form the meat mixture into a loaf shape and place it in the pan or on the baking sheet. Spread half of the caramelized onions over the top of the meatloaf.
4. Bake and Add the Cheese:
Bake the meatloaf uncovered in the preheated oven for 45 minutes. After that time, take it out and layer the Swiss cheese evenly over the top, followed by the remaining caramelized onions.
5. Finish Baking:
Return the meatloaf to the oven and bake for another 10-15 minutes, or until the cheese is melted and the internal temperature reads 160°F (71°C). Once done, remove it from the oven and let it rest for 10 minutes before slicing into it.
6. Serve:
To serve, garnish with freshly chopped parsley. This savory dish is perfect with mashed potatoes or a side of veggies. Enjoy the rich flavors and comforting warmth of your homemade French Onion Meatloaf!
