Ingredients You’ll Need

These ingredients are deceptively simple but incredibly essential. Each one plays a crucial role in building layers of flavor, texture, and color that make this French Onion Meatloaf such a standout dish.

• 1 lb ground beef (80% lean): Provides the juicy base and hearty flavor essential for meatloaf.
• 1/2 lb ground pork: Adds a bit of sweetness and moisture, balancing the beef perfectly.
• 1 small onion, finely chopped: Caramelized to bring sweet, savory depth to the meat mixture.
• 1 tablespoon olive oil: For caramelizing the onions, unlocking their natural sweetness.
• 1 clove garlic, minced: Adds a subtle pungency that enhances overall flavor.
• 1/2 cup breadcrumbs: Helps bind everything together and keeps the meatloaf tender.
• 1/4 cup milk: Moisturizes the breadcrumbs, keeping the texture soft and pleasant.
• 1 large egg: The glue that holds all components together perfectly.
• 1 packet French onion soup mix: The secret ingredient that infuses this meatloaf with classic French onion flavor.
• 1 teaspoon Worcestershire sauce: Adds umami and depth, elevating the savory profile.
• Salt and pepper, to taste: Essential seasonings that bring out the natural flavors.
• 1/4 cup ketchup: The base of the glaze, providing a sweet tang.
• 1 tablespoon Dijon mustard: Adds a sharp, sophisticated kick to the glaze.

How to Make French Onion Meatloaf

Step 1: Caramelize the Onions and Garlic

Start by heating olive oil in a skillet over medium heat. Add the finely chopped onion and cook it slowly, stirring often for about 10 to 12 minutes until it turns golden and sweetly caramelized. Toss in the minced garlic during the last minute just to bring out its fragrance without burning it. This step is absolutely crucial because these onions will be the heart and soul of your French Onion Meatloaf, contributing that luscious sweetness and deep flavor that set this meatloaf apart.

Step 2: Mix the Meatloaf Ingredients

Preheat your oven to 350 degrees Fahrenheit (175 Celsius). In a large bowl, combine the ground beef, ground pork, breadcrumbs, milk, egg, French onion soup mix, Worcestershire sauce, salt, and pepper. Then, fold in the cooled caramelized onions and garlic. This mixture is where all the magic happens — every ingredient mingles perfectly, ensuring every bite of the French Onion Meatloaf bursts with savory, comforting goodness.

Step 3: Shape and Bake the Meatloaf

Transfer your delicious mixture into a loaf pan and gently shape it into a loaf. Baking it at 350 degrees Fahrenheit for 50 to 60 minutes allows the meatloaf to cook evenly and hold its shape while becoming wonderfully juicy inside. Keep an eye out for when the internal temperature reaches 160 degrees Fahrenheit (71 Celsius) — that’s your signal that perfection has been reached.

Step 4: Prepare and Apply the Glaze

While the meatloaf bakes, whisk together ketchup, Dijon mustard, brown sugar, soy sauce, and Worcestershire sauce in a small bowl. After about 40 minutes of baking, take the meatloaf out and slather this glaze evenly over the top. Return it to the oven for another 10 to 15 minutes to let the glaze set and bubble into a sticky, flavorful crust. This glaze beautifully complements the meat and onions, adding a delightful sweet tangy finish.

Step 5: Rest Before Serving

Once out of the oven, let the French Onion Meatloaf rest for 10 minutes before slicing. This resting period allows juices to redistribute, ensuring each slice is moist and tender rather than crumbly. Trust me, this little pause makes a world of difference in the final presentation and taste experience.

How to Serve French Onion Meatloaf

Garnishes

A sprinkle of freshly chopped parsley or chives right before serving adds a lovely burst of color and a hint of freshness that contrasts beautifully with the meaty richness of the French Onion Meatloaf. You could also add a spoonful of caramelized onions on top for an extra indulgent touch.

Side Dishes

Classic sides like creamy mashed potatoes and steamed green beans are absolute winners here, soaking up the savory glaze and making every bite even more comforting. Roasted carrots or a crisp Caesar salad also pair wonderfully, adding texture and balancing the richness with freshness.

Creative Ways to Present

Want to impress guests? Slice the French Onion Meatloaf thick, stack it on toasted artisan bread, and top with melted Swiss or Gruyère cheese for a decadent meatloaf sandwich. Another fun idea is to serve mini meatloaf “cakes” topped with a dollop of tangy sour cream or horseradish sauce for a party appetizer twist!

Make Ahead and Storage

Storing Leftovers

Leftover French Onion Meatloaf keeps beautifully in the refrigerator for up to 3 days. Be sure to store it in an airtight container to maintain moisture and flavor — it reheats just as deliciously, making lunch or dinner the next day simple and satisfying.

Freezing

This meatloaf freezes wonderfully, making it an excellent meal prep candidate. Wrap it tightly in plastic wrap and aluminum foil or store in a freezer-safe container. It will keep well for up to 2 months, ready to thaw and reheat for a comforting dinner in a pinch.

Reheating

To reheat, cover the meatloaf with foil and warm it in a 325 degrees Fahrenheit oven until heated through, usually about 20 minutes. This prevents it from drying out while maintaining that tender texture and sticky glaze that make the French Onion Meatloaf so crave-worthy.

FAQs

Can I make this French Onion Meatloaf gluten-free?

Absolutely! Just substitute the breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers to keep that perfect texture without gluten.

Is it possible to use all beef instead of mixing pork and beef?

Yes, using all ground beef works fine. The pork adds extra moisture and slight sweetness, but beef alone will still yield a delicious French Onion Meatloaf.

Can I prepare the meatloaf mixture ahead of time?

You can mix it up to a day in advance and keep it covered in the fridge. This allows the flavors to meld even more — just shape and bake when you’re ready.

What if I don’t have French onion soup mix?

You can substitute with a combination of dried onion flakes, beef bouillon powder, and a pinch of garlic powder to mimic that iconic flavor.

Can I use a glaze other than the one suggested?

Definitely! While the classic glaze balances sweet and tangy perfectly, feel free to experiment with BBQ sauce or a tomato-based glaze for different flavor profiles on your French Onion Meatloaf.
