• Ground beef (80% lean): The classic foundation that gives your meatloaf its hearty flavor and juicy bite.
• Ground pork: Adds extra richness and ensures every slice stays tender and moist.
• Onion, finely chopped: Essential for that deep, sweet caramelized onion flavor that makes this recipe shine.
• Olive oil: The key to sauteing your onions, bringing out all their natural sweetness.
• Garlic, minced: Just a clove elevates the savory notes and rounds out the entire dish.
• Breadcrumbs: The secret to a light texture that holds everything together without drying out the loaf.
• Milk: Helps soften the breadcrumbs and keeps the meatloaf perfectly juicy.
• Egg: Acts as the binding agent so your loaf slices neatly and tastes divine bite after bite.
• French onion soup mix: Adds instant depth and that unmistakable French onion flavor with minimal effort.
• Worcestershire sauce: A splash ups the umami and gives your meatloaf a delicious, savory undertone.
• Salt and pepper, to taste: Balance and brighten all those rich flavors; season with a gentle hand.
• Ketchup (for glaze): Brings a sweet-tangy gloss to the finished loaf, making each bite irresistible.
• Dijon mustard (for glaze): Adds a subtle zippy warmth that cuts through the richness.
• Brown sugar (for glaze): For a deep caramel flavor on the glazed topping.
• Soy sauce (for glaze): Contributes an extra layer of savory magic—trust me, it works!

How to Make French Onion Meatloaf

Step 1: Caramelize the Onions and Garlic

Start things off by heating the olive oil over medium heat and dropping in those finely chopped onions. This is where the character of your French Onion Meatloaf is born—you want soft, golden, deeply caramelized onions that coax sweetness from every slice. Give it a full 10-12 minutes, stirring often so nothing burns. In the last minute, toss in your garlic just until fragrant. Set aside to cool before mixing into the meat.

Step 2: Blend the Meatloaf Mixture

With your onions cooling, grab a large mixing bowl. Add your ground beef and pork, milk-soaked breadcrumbs, egg, that reliable French onion soup mix, Worcestershire sauce, and a careful sprinkle of salt and pepper. Fold in the caramelized onion and garlic mixture, then mix by hand—gently! The less you work it, the more tender your loaf. You’ll know it’s perfect when everything is just combined and speckled with little oniony jewels.

Step 3: Shape and Bake the Loaf

Scoop your mixture into a loaf pan and shape it evenly for a gorgeous, hearty slab. Slide it into a preheated 350°F oven and bake for 50-60 minutes. It’s worth waiting for that internal temperature of 160°F—this is how you know your French Onion Meatloaf is done and supremely juicy inside.

Step 4: Whip Up the Glaze

While your kitchen is starting to smell amazing, mix up your glaze: whisk together ketchup, Dijon mustard, brown sugar, soy sauce, and just a touch more Worcestershire. After about 40 minutes of baking, generously brush this glossy, flavor-packed glaze over your meatloaf. Pop it back into the oven for the last 10-15 minutes until bubbly and caramelized.

Step 5: Rest and Slice

Once baked, patience pays off—let your meatloaf rest for a good 10 minutes. This helps all those juices redistribute, so every slice stays moist and beautiful. Grab your sharpest knife and cut into hearty, aromatic slices that are ready for all your favorite sides.

How to Serve French Onion Meatloaf

Garnishes

Nothing finishes off a French Onion Meatloaf like a flourish of fresh parsley or a sprinkle of crispy fried onions on top for extra crunch and eye appeal. If you’re feeling decadent, a few shavings of Gruyère or Swiss cheese melted over hot slices echo the best part of French onion soup.

Side Dishes

Pairing is half the fun! Classic mashed potatoes catch all those savory juices, while roasted green beans or buttered peas bring freshness to every forkful. For something special, consider a crisp green salad with sharp vinaigrette to balance the richness.

Creative Ways to Present

For a fun twist, slice the meatloaf and tuck it into crusty rolls with extra sauce for mouthwatering sandwiches. Or, arrange slices on a platter with caramelized onions and cheese for a bistro-style meatloaf board—guaranteed crowd-pleaser!

Make Ahead and Storage

Storing Leftovers

Leftover French Onion Meatloaf holds up wonderfully. Cover tightly with foil or transfer to an airtight container, then refrigerate—it’ll stay delicious for up to 4 days, making weekday lunches a breeze.

Freezing

You can easily freeze whole or sliced portions. Once completely cooled, wrap in foil and place in a freezer bag or container. Label and date—you’ll thank yourself later. For best texture, enjoy within 2 months.

Reheating

Reheat slices in the oven, covered, at 325°F until warmed through for the best results. For single servings, a splash of broth and a minute or two in the microwave keeps things moist and tasty.

FAQs

Can I use only ground beef instead of a beef and pork mix?

Yes, but the pork adds a certain juiciness and gentle flavor you’ll miss. All beef works in a pinch—just don’t choose anything too lean, or the French Onion Meatloaf texture may be dry.

What can I substitute for the French onion soup mix?

If you’re looking to avoid premade soup mix, double the amount of caramelized onion, add a pinch of dried thyme, and a dash of beef bouillon for a homemade punch of umami.

Why is my meatloaf falling apart?

Too little binder (egg or breadcrumbs), overmixing, or not letting it rest can lead to crumbling. Follow the steps closely and your French Onion Meatloaf will slice like a dream.

Can I assemble ahead and bake later?

Absolutely! Shape the loaf and cover, then refrigerate up to a day ahead. Let it come to room temperature before baking for best results, ensuring even cooking.

Is this recipe kid-friendly?

Very much so! The caramelized onions mellow out beautifully, the glaze is both sweet and savory, and you can always adjust seasonings to please younger palates.
