Ingredients You’ll Need

This French Onion Meatloaf keeps things remarkably simple yet achieves irresistible depth, thanks to a handful of carefully chosen ingredients. Each one plays an important role—whether for moisture, savoriness, or that irresistible cheesy kiss on top!

• Ground Beef: Use 2 pounds for a juicy, rich loaf; ground turkey is a leaner alternative but still packs a ton of flavor.
• Caramelized Onions: Slow-cooked, golden-sweet onions infuse the entire meatloaf with that signature French onion flair.
• Breadcrumbs: 1 cup helps bind everything together without making the loaf dense; gluten-free works perfectly too.
• Shredded Cheese: ½ cup of Swiss or Gruyere is the magic melter—choose one for classic French onion taste.
• Egg: One large egg brings the mix together, ensuring slices hold up beautifully.
• Garlic Powder: 1 teaspoon adds subtle warmth, letting the onions and cheese stay center stage.
• Thyme: 1 teaspoon enhances the herbal notes and gives a nod to classic French flavors.
• Salt and Pepper: A generous pinch of each heightens and balances the other flavors.
• Optional Onion Soup Mix: For anyone craving that nostalgic, extra-savory kick, stir in a packet for big flavor payoff.

How to Make French Onion Meatloaf

Step 1: Prepare and Caramelize the Onions

Start by thinly slicing two large onions. Toss them in a skillet with a drizzle of olive oil over medium heat, and let them gently brown for about 20 to 25 minutes. Stir regularly, savoring the sweet aroma as the onions turn irresistibly golden and jammy—the backbone of French Onion Meatloaf’s flavor.

Step 2: Mix the Ingredients

Let your caramelized onions cool a little, then combine them in a big mixing bowl with the ground beef (or turkey), breadcrumbs, shredded Swiss or Gruyere, egg, garlic powder, thyme, salt, and pepper. If you’re using onion soup mix, add it here. Mix gently—just enough to combine everything evenly so your French Onion Meatloaf stays juicy and tender.

Step 3: Shape the Meatloaf

Turn the mixture out onto a parchment-lined baking sheet, shaping it into a generous loaf. You can also use a loaf pan for tidy edges and even cooking. Be careful not to pack it down too tightly; a light hand means a softer, more luscious meatloaf after baking.

Step 4: Bake to Perfection

Slide your French Onion Meatloaf into a preheated 375°F (190°C) oven and bake for 50 to 60 minutes. It’s ready when a thermometer stuck into the center reads 160°F (71°C). If you’d love an extra-cheesy top, try sprinkling on more cheese during the last 10 minutes of baking!

Step 5: Rest and Slice

Once out of the oven, let your meatloaf rest for 5 to 10 minutes. This little pause makes the juices settle, so every slice will be moist, hearty, and loaded with flavor—a reward well worth the wait!

How to Serve French Onion Meatloaf

Garnishes

A finishing touch makes all the difference! Scatter some fresh thyme leaves or chopped parsley over your French Onion Meatloaf for a pop of color. For extra decadence, a handful of crispy fried onions (store-bought or homemade) adds both crunch and drama on top.

Side Dishes

Classic mashed potatoes, garlicky green beans, or a crisp green salad all make dreamy partners for French Onion Meatloaf. The rich meat and sweet onions pair wonderfully with simple sides that sop up extra juices and balance the hearty flavors.

Creative Ways to Present

For a special meal, slice the meatloaf thick and layer on a melted cheese topping, broiling for just a minute until bubbly. Or serve mini French Onion Meatloaf “sliders” on soft rolls with a swipe of garlic aioli for a fun, casual twist. Leftovers also shine as an elevated sandwich filling!

Make Ahead and Storage

Storing Leftovers

Leftover French Onion Meatloaf is a lifesaver on busy days! Store slices in an airtight container in the refrigerator, where they’ll stay delicious for up to four days. The flavors actually deepen overnight, making your lunches and weeknight meals quick and satisfying.

Freezing

French Onion Meatloaf is ideal for freezing either before or after baking. Wrap tightly in plastic wrap and foil, then freeze for up to three months. Defrost overnight in the fridge before baking or reheating, and you’ll have a comforting dinner ready to go with hardly any work.

Reheating

The best way to gently reheat French Onion Meatloaf is in a 325°F oven, covered with foil to lock in moisture. For a quick fix, slices can be microwaved too—just splash a little broth over them to keep things nice and juicy. Add a sprinkle of cheese on top for an instant upgrade!

FAQs

Can I make French Onion Meatloaf with ground turkey?

Absolutely! Ground turkey works beautifully in this recipe, yielding a lighter (but still flavorful) French Onion Meatloaf. You may want to add a splash of milk or extra cheese to keep things moist.

What cheese should I use for the classic flavor?

Swiss and Gruyere are the traditional choices for authentic French onion flair, thanks to their nutty, meltable qualities. For a change, try provolone or a mix of your favorites—you can’t go wrong!

Can I prepare French Onion Meatloaf ahead of time?

Yes, you can shape the loaf a day in advance and refrigerate it, covered, before baking. This makes hosting a breeze and lets the flavors deepen even more before it hits the oven.

How do I keep my meatloaf from falling apart?

Be sure to let your French Onion Meatloaf rest for at least 5 minutes after baking. The egg and breadcrumbs act as binders, but taking it easy when mixing and shaping helps everything stay together for perfect slices every time.

What’s the best way to reheat leftovers?

For best results, reheat slices of French Onion Meatloaf in the oven, covered with foil. This prevents drying out and helps the cheese stay gooey. The microwave works in a pinch—just add a little broth if needed!
