How to Make Savory French Onion Meatloaf

Step 1: Caramelize the Onions

Start with the onions, since these take the longest:

1. Heat 2 tablespoons of butter in a medium skillet over medium-low heat.
2. Add the thinly sliced onions and cook, stirring occasionally, for 25–30 minutes until golden and soft.
3. Stir in the balsamic vinegar and sugar. Let it reduce slightly.
4. Add beef broth and simmer until onions are jammy and the liquid has mostly evaporated.
5. Season with salt and pepper to taste, then remove from heat and set aside.

Pro Tip: Low and slow is key to perfect caramelized onions. Don’t rush it—you want golden brown, not burnt.

Step 2: Prepare the Meatloaf Mixture

1. Preheat your oven to 375°F (190°C).
2. In a large bowl, mix breadcrumbs and milk. Let it soak for 5 minutes.
3. Add ground beef, ground pork, chopped onion, minced garlic, egg, Worcestershire, Dijon mustard, thyme, salt, and pepper.
4. Mix everything gently with your hands or a wooden spoon until just combined. Avoid overmixing to keep the loaf tender.
5. Form the mixture into a loaf shape and place in a greased loaf pan or on a parchment-lined baking tray.

Step 3: Bake the Meatloaf

1. Bake for 45 minutes uncovered.
2. Remove the meatloaf from the oven and evenly layer the caramelized onions on top.
3. Sprinkle the shredded Swiss cheese generously over the onions.
4. Return to the oven and bake for another 10–15 minutes, or until cheese is melted and bubbly.

Optional: Broil for 1–2 minutes for a golden, bubbly cheese top.

5. Let the meatloaf rest for 10 minutes before slicing to allow juices to redistribute.

Serving Suggestions

This meatloaf pairs beautifully with:

• Mashed potatoes – Classic and indulgent, just like the meatloaf.
• Green beans almondine – A crisp, fresh contrast to the richness.
• Crusty French bread – To soak up any extra oniony goodness.
• Red wine – Try a Pinot Noir or Merlot to match the savory notes.

Leftovers & Storage

Fridge:

• Store leftovers in an airtight container for up to 4 days.
• Reheat slices in the microwave or oven until warmed through.

Freezer:

• Wrap individual slices tightly in plastic wrap and foil.
• Freeze for up to 2 months.
• To reheat, thaw overnight in the fridge and warm in the oven at 350°F.

Recipe Tips & Variations

Tips:

• Don’t overmix the meat mixture — overworking can make the loaf tough.
• Use a meat thermometer — internal temp should be 160°F for beef/pork.
• Let it rest after baking — this helps maintain moisture and structure.

Variations:

• Mushroom lovers: Add sautéed mushrooms to the onion mix for an earthy upgrade.
• Spicy twist: Add crushed red pepper or swap Swiss for pepper jack cheese.
• Gluten-free: Use gluten-free breadcrumbs or rolled oats.
• Cheese swap: Gruyère is a fantastic substitute for Swiss cheese.

Frequently Asked Questions (FAQs)

Can I make this meatloaf in advance?
Absolutely! You can assemble the loaf and refrigerate it for up to 24 hours before baking. Let it sit at room temperature for 30 minutes before baking.

Can I use all beef instead of pork and beef?
Yes, but keep in mind that pork adds moisture and flavor. If using all beef, consider using an 80/20 blend for juiciness.

Can I double the recipe?
Definitely! Just use a larger loaf pan or divide the mixture into two loaves and extend baking time slightly. Always check internal temperature.

What other cheese works besides Swiss?
Gruyère is a close match with a stronger flavor. Mozzarella works for meltiness but is milder. Provolone also complements the flavors well.

Do I need to cook the onions for that long?
Yes! Caramelizing onions properly takes 25–30 minutes. That’s what brings out their sweetness and signature flavor.
