Ingredients You’ll Need

Getting the ingredients for this French Onion Meatloaf is a breeze, and each one plays a crucial role in building layers of flavor and texture. From the ground beef that delivers juicy heartiness to the caramelized onions packing a sweet umami punch, every element counts.

• Ground Beef (or turkey for a lean option): Provides the main protein and a juicy base that keeps the meatloaf tender.
• Caramelized Onions: Two large thinly sliced onions slowly cooked until golden brown add deep, sweet flavor and moisture.
• Breadcrumbs: A cup to bind ingredients and keep the meatloaf from becoming too dense; gluten-free options work great too.
• Shredded Cheese (Swiss or Gruyere): Half a cup to add creamy melt-in-your-mouth richness and a nod to the classic French onion soup.
• Egg: Acts as a binder helping everything stay together perfectly.
• Garlic Powder: A teaspoon to enhance the savory profile without overpowering other flavors.
• Thyme: Another teaspoon for a subtle herbaceous note that complements the onions brilliantly.
• Salt and Pepper: To taste, essential seasonings that bring all the ingredients into harmony.
• Optional: Onion soup mix: Sprinkled in for an extra layer of the signature French onion flavor.

How to Make French Onion Meatloaf

Step 1: Caramelize the Onions

Begin by thinly slicing two large onions and cooking them slowly in olive oil over medium heat. This step takes about 20 to 25 minutes, but it’s worth every second. The onions will beautifully brown and soften, developing a sweet, rich flavor that’s the soul of this meatloaf.

Step 2: Mix Ingredients Together

Once the onions have cooled a bit, combine them with ground beef, breadcrumbs, shredded cheese, egg, garlic powder, thyme, salt, and pepper in a large bowl. If you’re using onion soup mix, add it now to amp up the flavor. Mix everything gently, just until combined, to keep your meatloaf tender.

Step 3: Shape the Meatloaf

Shape the mixture into a loaf on a lined baking sheet or press it into a loaf pan for neater edges. This shaping locks in moisture during baking and ensures the loaf cooks evenly.

Step 4: Bake to Perfection

Preheat your oven to 375ºF (190ºC) and bake the meatloaf for 50 to 60 minutes. It’s done when the internal temperature reaches 160ºF (71ºC), guaranteeing a juicy, perfectly cooked center surrounded by that golden crust.

Step 5: Rest Then Slice

Let the meatloaf rest for 5 to 10 minutes after baking. This allows the juices to redistribute, making each slice moist and flavorful instead of falling apart.

Freezing

This meatloaf freezes beautifully. Wrap it tightly in plastic wrap and foil or place it in a freezer-safe container. It can be frozen for up to 3 months without losing flavor or texture.

FAQs

Can I use ground turkey instead of beef?

Absolutely! Ground turkey is a leaner option that works well in French Onion Meatloaf. Just keep in mind it might be slightly less juicy, so be gentle when mixing and consider adding a bit of extra moisture like a splash of broth or an additional egg.

Is there a vegetarian version of this recipe?

While this recipe is designed for meat, you can try substituting the ground beef with plant-based ground meat alternatives and use vegetable broth in place of any broth or onion soup mix. Caramelized onions and cheese help retain that rich flavor.

How do I know when the meatloaf is fully cooked?

The best way is to use a meat thermometer. When the internal temperature reaches 160ºF (71ºC), your French Onion Meatloaf is safely cooked and ready to enjoy.

Can I add extra vegetables to this meatloaf?

Yes, finely chopped mushrooms, bell peppers, or carrots can be added to the mix for extra nutrition and texture. Just sauté them lightly before mixing to reduce moisture that could make the meatloaf too soggy.

What cheese works best for the French Onion Meatloaf?

Swiss and Gruyere are traditional choices because they melt beautifully and complement caramelized onions with their nutty flavor. However, you can experiment with mozzarella or provolone if you prefer a milder cheese.
