Step 3: Incorporate the Onions

Take about half of the caramelized onions and mix them directly into the meat mixture.

This distributes the sweet onion flavor throughout the meatloaf.

Reserve the remaining onions for topping later.

Step 4: Shape the Meatloaf

1. Preheat your oven to 375°F (190°C).
2. Line a baking sheet with parchment paper or lightly grease a loaf pan.
3. Shape the meat mixture into a loaf shape about 8 inches long.

Place it in the prepared pan.

Step 5: Bake the Meatloaf

Place the meatloaf in the oven and bake for 35 minutes.

During this time the loaf will firm up and begin developing flavor.

Step 6: Add Onions and Swiss Cheese

1. Remove the meatloaf from the oven.
2. Spread the remaining caramelized onions over the top.
3. Lay Swiss cheese slices across the entire loaf.

Return the meatloaf to the oven.

Bake for 10–15 more minutes, or until:

• The cheese is melted and bubbly
• The internal temperature reaches 160°F (71°C)

Step 7: Rest Before Slicing

Allow the meatloaf to rest for 5–10 minutes before cutting.

This step helps the juices redistribute, keeping the meat moist.

Serving Suggestions

This French onion meatloaf pairs wonderfully with classic comfort sides:

• Creamy mashed potatoes
• Roasted vegetables
• Buttered green beans

A spoonful of the onion sauce from the pan drizzled over each slice makes the dish even more flavorful.

Tips for the Best Meatloaf

1. Take time with the onions
Slow caramelization creates the deep flavor that defines the dish.

2. Use breadcrumbs and milk
This combination keeps the meatloaf tender.

3. Don’t overmix the meat
Mix only until ingredients are combined.

4. Check the temperature
A meat thermometer ensures perfectly cooked meatloaf.
