Ingredients You’ll Need

The best part about French Onion Meatloaf is how it relies on a handful of accessible ingredients, each one playing a crucial role. The proteins, seasonings, and optional extras meld together into an irresistible, flavor-packed centerpiece.

• Ground Beef (80% lean): Adds hearty flavor and helps create that classic meatloaf texture everyone loves.
• Ground Pork: Brings extra richness and juiciness that puts this meatloaf above the rest.
• Small Onion, finely chopped: The foundation of French onion flavor—caramelized for sweetness and depth.
• Olive Oil: Helps soften and caramelize onions beautifully.
• Garlic, minced: Gives aromatic background notes that round out the flavor profile.
• Breadcrumbs: Binds everything together and gives the loaf structure.
• Milk: Softens the breadcrumbs, creating a tender, moist loaf.
• Large Egg: Ensures the meatloaf holds its shape without crumbling.
• French Onion Soup Mix: Shortcut seasoning that delivers concentrated, satisfying onion flavor with every bite.
• Worcestershire Sauce: Adds that signature savory, umami punch.
• Salt and Pepper: Balances the flavors and brings out the best in the meat.
• Ketchup (for glaze): The tangy-sweet base for a perfectly glazed top.
• Dijon Mustard (for glaze): Brings a bit of zip to the glaze, making it pop.
• Brown Sugar (for glaze): Offers gentle sweetness and helps the glaze caramelize beautifully.
• Soy Sauce (for glaze): Adds a rich, salty depth that complements the onions perfectly.
• Worcestershire Sauce (for glaze): The not-so-secret ingredient that infuses the glaze with irresistible savory vibes.

How to Make French Onion Meatloaf

Step 1: Caramelize the Onions

Start by heating the olive oil in a skillet over medium heat. Add the finely chopped onions and let them cook low and slow for about 10 to 12 minutes, stirring frequently. You want them to reach a soft, golden-brown color for maximum sweetness and flavor. Add the minced garlic during the last minute—you’ll notice the kitchen instantly smells amazing! Remove the onion-garlic mixture from the heat and let it cool while you prep the other ingredients.

Step 2: Mix Up the Meatloaf Base

Preheat your oven to 350°F (175°C). In a large bowl, combine the ground beef and pork, breadcrumbs, milk, egg, French onion soup mix, Worcestershire sauce, salt, and pepper. Now, fold in those luscious caramelized onions and garlic. Use your hands (with clean fingers!) to mix everything together just until fully combined—over-mixing can make meatloaf dense. It’s almost time for some oven magic.

Step 3: Shape and Bake the Loaf

Transfer your savory meat mixture into a loaf pan, shaping it into a neat loaf that fills the pan evenly. Slide it into the preheated oven and bake for 50 to 60 minutes; you’re looking for an internal temperature of 160°F (71°C) to ensure it’s fully cooked but still juicy. The anticipation at this point is real!

Step 4: Prepare and Spread the Glaze

While the meatloaf bakes, whisk together ketchup, Dijon mustard, brown sugar, soy sauce, and Worcestershire sauce for your glaze. Once the meatloaf has baked for about 40 minutes, pull it out (carefully!), spread the glaze generously over the top, and return it to the oven. Bake for another 10 to 15 minutes until the glaze is set and deliciously bubbly.

Step 5: Rest and Slice

Let your French Onion Meatloaf rest for 10 minutes after it comes out of the oven. This gives all those tasty juices a chance to settle, so each slice is moist and full of rich, developed flavor. Now, it’s ready to serve!

How to Serve French Onion Meatloaf

Garnishes

A classic French Onion Meatloaf truly shines when adorned with a sprinkle of chopped fresh parsley or even some crispy fried onions on top for an extra touch of crunch and onion flavor. If you love cheese, a dusting of grated Gruyère or Swiss as it comes out of the oven really nods to the classic soup inspiration.

Side Dishes

Pair your meatloaf with buttery mashed potatoes or creamy garlic mashed cauliflower—both catch those savory juices beautifully! Roasted green beans or glazed carrots make a colorful, fresh counterpoint. And if you’re feeling fancy, a side of garlicky French bread for soaking up every bit of the sauce is sheer perfection.

Creative Ways to Present

Transform leftovers into unforgettable sandwiches with thick slices of French Onion Meatloaf on toasted sourdough, a swipe of grainy mustard, and maybe some melted Gruyère. For a dinner party twist, slice the meatloaf into individual servings and top with little caramelized onion nests. A drizzle of extra glaze or a dollop of creamy horseradish sauce can make each plate restaurant-worthy!

Make Ahead and Storage

Storing Leftovers

French Onion Meatloaf keeps beautifully in the refrigerator for up to 4 days. Wrap any leftovers tightly in foil or store them in a sealed container to retain all that moisture and flavor. When stored right, every bite reheats just as juicy as the first serving.

Freezing

If you’re looking to prep French Onion Meatloaf ahead of time, wrap the cooled loaf (whole or sliced) in a layer of plastic wrap followed by foil, and freeze for up to 3 months. Just be sure to label it, so future you knows there’s a homemade dinner waiting without any mystery!

Reheating

For best results, reheat slices gently in the oven at 325°F (163°C), covered loosely with foil, until warmed through. If you’re in a rush, the microwave works too—just cover the meatloaf with a damp paper towel to keep it moist and pop it in for a minute or two. Add a little fresh glaze or jus to liven up every serving!

FAQs

Can I use only beef for this French Onion Meatloaf?

Absolutely! While a beef-pork blend adds extra moisture and flavor, using 100% ground beef will still yield a fantastic loaf. Just choose 80% lean for best results, and maybe add a touch more milk if you’re worried about dryness.

Is it possible to make this recipe gluten-free?

Yes! Swap out the regular breadcrumbs for your favorite gluten-free variety and double-check your French onion soup mix and soy sauce labels for any hidden gluten. The result is every bit as satisfying and savory.

Can I prepare French Onion Meatloaf ahead and bake it later?

Definitely! You can assemble the loaf, cover it tightly, and refrigerate it unbaked for up to 24 hours. Just bring it to room temperature for 20 minutes before baking, then continue with the recipe as written. Meal prep made simple!

What type of onion works best?

A standard yellow onion is perfect here—it caramelizes beautifully and brings that signature French onion flavor. Sweet onions will add more sugariness, while white onions offer a sharper note, so feel free to experiment based on your tastes.

What’s the secret to juicy meatloaf?

The secret is a combination of milk-soaked breadcrumbs, a blend of proteins, and not overworking the meat mixture. Also, giving the loaf a little rest before slicing ensures every bite is juicy and tender, so patience definitely pays off!

Final Thoughts

I hope you’ll make French Onion Meatloaf a regular star at your dinner table! It’s a guaranteed crowd-pleaser that transforms the humble meatloaf into something truly special. Give it a try, and watch your family’s eyes light up at first bite!
