4. Bake for 40–45 minutes, or until the internal temperature reaches 160°F (71°C).

2. Caramelize the Onions

1. While the meatloaf bakes, heat butter and olive oil in a skillet over medium heat.
2. Add sliced onions, sugar, and salt, stirring occasionally. Cook slowly for 25–30 minutes until deep golden brown.
3. Stir in beef broth and Worcestershire sauce, allowing the mixture to simmer and slightly thicken.

3. Smother the Meatloaf

2. Spoon the caramelized onion mixture over the top.

4. Melt the Cheese & Serve

1. Return the meatloaf to the oven for another 5–10 minutes, or until the cheese is melted and bubbly.
2. Let it rest for 5 minutes before slicing.
3. Serve with mashed potatoes, roasted vegetables, or a fresh side salad.

Tips for the Best French Onion Meatloaf

Troubleshooting & Common Mistakes

Even the best meatloaf recipes can go wrong if you’re not careful. Here are some common mistakes people make with French Onion Smothered Meatloaf—and how to avoid them!

Meatloaf Turns Out Dry

Solution:

• Use 80/20 ground beef (or a mix of beef and pork) to keep it juicy.
• Don’t skip the milk and egg—they help bind and moisten the meat.
• Let the meatloaf rest for at least 5 minutes after baking before slicing.

Onions Burn Instead of Caramelize

Solution:

• Cook the onions low and slow over medium-low heat for 25–30 minutes.
• Add a little sugar to help the caramelization process.
• If onions start burning, reduce heat and add a splash of water or beef broth.

Cheese Burns or Doesn’t Melt Properly

Solution:

• Add the cheese in the last 5–10 minutes of baking, so it melts without burning.
• Use freshly shredded cheese instead of pre-shredded (which contains anti-caking agents that prevent proper melting).

Meatloaf Falls Apart When Sliced

Solution:

• Use the right ratio of meat to breadcrumbs and egg to ensure it holds together.
• Let the meatloaf cool slightly before slicing, so the juices redistribute and help keep its shape.

• Low-Sodium Beef Broth – Reduces salt intake without compromising flavor.

FAQs About French Onion Smothered Meatloaf

1. Can I make this meatloaf ahead of time?

Yes! You can prepare the meatloaf mixture a day in advance and store it covered in the fridge. When ready to bake, just pop it in the oven and follow the instructions.

You can also fully bake the meatloaf ahead of time, then reheat it with the onions and cheese before serving.

2. Can I use a different type of meat?

Absolutely! While ground beef is traditional, you can also use:

• Ground turkey – Leaner, but still juicy when paired with the onions.
• Ground pork – Adds a little more fat and flavor.
• Ground chicken – Works great if you’re looking for a lighter alternative.
• A mix of beef and pork – Adds the perfect balance of richness and tenderness.

3. What’s the best cheese to use?

The best cheeses for this recipe are:

• Gruyère – The most authentic choice with a nutty, slightly sweet flavor.
• Swiss cheese – Milder and slightly nutty.
• Provolone – Melts beautifully and adds a creamy texture.
• Mozzarella – If you prefer a gooey, stretchy cheese.

Avoid cheeses that don’t melt well, like feta or parmesan.

4. How do I keep my meatloaf from falling apart?

To ensure your meatloaf holds its shape:

• Don’t skip the egg and breadcrumbs – These act as binding agents.
• Mix the ingredients just enough – Over-mixing can make the meatloaf too dense and dry.
• Let it rest before slicing – If you cut into it right away, the juices will escape, making it more crumbly.

5. Can I make this meatloaf in a different shape?

Yes! Instead of a traditional loaf shape, you can:

6. How do I thicken my caramelized onion sauce?

If you want a thicker sauce, try:

• Adding a little cornstarch slurry (mix 1 tsp cornstarch with 1 tbsp water).
• Letting it simmer longer to reduce the liquid.
• Sprinkling in a little flour and stirring well before adding broth.
