Last Updated on March 22, 2025 by Souhail

Meatloaf is a timeless comfort food, but have you ever tried a French onion meatloaf recipe? This dish takes all the rich, savory flavors of classic French onion soup and infuses them into a juicy, cheesy meatloaf that will have your taste buds dancing.

Perfect for weeknight dinners or Sunday family meals, this meatloaf features caramelized onions, melty cheese, and a flavorful glaze that keeps every bite moist and delicious. Whether you’re a long-time meatloaf lover or looking for a fresh way to enjoy this traditional dish, this recipe delivers the ultimate comfort food experience.

Why This Recipe Works

This French onion meatloaf recipe stands out because of its deep, rich flavors and gooey cheese center. Here’s why you’ll love it:

• Caramelized onions add incredible depth: Cooking the onions low and slow brings out their natural sweetness, enhancing the overall taste.
• A cheese-stuffed center: Unlike traditional meatloaf, this version is filled with Gruyère or Swiss cheese, making it irresistibly creamy.
• Moist and tender texture: A mix of ground beef and pork (or your choice of protein) ensures juiciness in every bite.
• Savory glaze for extra flavor: A tangy glaze made with Worcestershire sauce, ketchup, and beef broth complements the meatloaf perfectly.
• Easy customization: You can make this meatloaf keto-friendly, gluten-free, or even swap proteins for a different taste.

Ingredients Breakdown

For the Caramelized Onions

• 2 tablespoons butter
• 2 large onions, thinly sliced
• ½ teaspoon salt
• ½ teaspoon sugar (optional, for faster caramelization)
• ¼ cup beef broth

For the Meatloaf

• 1 ½ pounds ground beef (or a mix of beef and pork)
• ½ cup breadcrumbs (or almond flour for a low-carb option)
• 1 egg, beaten
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 tablespoon Worcestershire sauce
• ½ cup caramelized onions (from above)
• ½ cup shredded Gruyère or Swiss cheese

And For the Glaze

• ¼ cup ketchup
• 1 tablespoon Worcestershire sauce
• ¼ cup beef broth

Step-by-Step Instructions

1. Caramelize the Onions (20-25 minutes)

1. In a large skillet, melt butter over medium-low heat.
2. Add sliced onions and sprinkle with salt and sugar.
3. Cook, stirring occasionally, for about 20 minutes until the onions turn deep golden brown.
4. Deglaze the pan with ¼ cup beef broth, scraping up any browned bits. Set aside.

2. Prepare the Meatloaf Mixture (10 minutes)

5. Preheat your oven to 375°F (190°C) and grease a loaf pan or line it with parchment paper.
6. In a large bowl, mix ground beef, breadcrumbs, egg, salt, pepper, garlic powder, onion powder, and Worcestershire sauce.
7. Stir in ½ cup caramelized onions for added flavor.

3. Assemble the Meatloaf (5 minutes)

8. Take half of the meat mixture and press it into the loaf pan.
9. Sprinkle ½ cup shredded cheese in the center, avoiding the edges.
10. Top with the remaining meat mixture, sealing the edges to encase the cheese.

4. Apply the Glaze & Bake (50-60 minutes)

11. In a small bowl, whisk together ketchup, Worcestershire sauce, and beef broth.
12. Brush half of the glaze over the meatloaf before baking.
13. Bake uncovered for 50-60 minutes until the internal temperature reaches 160°F (71°C).
14. In the last 10 minutes, brush with the remaining glaze for extra flavor.

5. Rest & Serve (10 minutes)

15. Remove the meatloaf from the oven and let it rest for 10 minutes to lock in juices.
16. Slice and serve warm with your favorite sides!

Pro Tips for Success

• Use a mix of meats: Combining ground beef with pork or veal enhances flavor and moisture.
• Don’t skip resting time: Letting the meatloaf sit before slicing prevents it from falling apart.
• Caramelize onions properly: Slow-cooked onions bring out the best flavors, don’t rush this step!
• Cheese alternatives: If you don’t have Gruyère, try mozzarella or provolone for a gooey texture.

Variants of the Recipe

1. Keto & Low-Carb French Onion Meatloaf

To make this recipe low-carb and keto-friendly, swap the breadcrumbs for almond flour or crushed pork rinds. You can also use sugar-free ketchup in the glaze and serve with cauliflower mash instead of traditional sides.

2. French Onion Turkey Meatloaf

For a leaner option, use ground turkey instead of beef. Since turkey is leaner, add an extra tablespoon of olive oil or heavy cream to keep it moist. The caramelized onions and cheese will still bring out amazing flavors!

3. French Onion Meatloaf with Bacon

For an extra smoky kick, wrap the meatloaf in bacon strips before baking. This creates a crispy, flavorful outer layer while sealing in moisture.

4. Gluten-Free French Onion Meatloaf

Simply replace breadcrumbs with gluten-free panko or oat flour. Double-check that your Worcestershire sauce is gluten-free, as some brands contain wheat.
