Ingredients
For the Meatloaf:
- 1 ½ lbs (680g) ground beef
- 1 cup caramelized onions (about 2 medium onions, thinly sliced)
- 1 cup French onion soup (canned or homemade)
- 1/2 cup breadcrumbs
- 1/4 cup milk
- 2 large eggs
- 2 cloves garlic, minced
- 1 teaspoon Worcestershire sauce
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried thyme or rosemary
For the Topping:
- 1/2 cup shredded Swiss or Gruyère cheese
- 1/4 cup caramelized onions (reserved from above)
- Optional: fresh thyme for garnish
Step-by-Step Instructions
Step 1: Caramelize the Onions
- Heat 1 tablespoon of olive oil or butter in a skillet over medium heat.
- Add thinly sliced onions and cook slowly, stirring occasionally, until golden brown and sweet, about 15–20 minutes. Set aside 1/4 cup for topping.
Step 2: Prepare the Meatloaf Mixture
- In a large bowl, combine ground beef, caramelized onions, breadcrumbs, milk, eggs, garlic, Worcestershire sauce, salt, pepper, and dried herbs.
- Mix gently until just combined; avoid overmixing to keep the meatloaf tender.
Step 3: Shape and Bake
- Preheat oven to 375°F (190°C).
- Shape the meat mixture into a loaf and place in a greased baking dish or loaf pan.
- Pour French onion soup over the top of the meatloaf to add flavor and moisture.
Step 4: Bake the Meatloaf
- Bake uncovered for 45–55 minutes, until the internal temperature reaches 160°F (71°C).
- About 10 minutes before the end of baking, sprinkle the shredded cheese and reserved onions over the top. Return to oven until cheese melts and slightly bubbles.
Step 5: Serve
- Allow the meatloaf to rest for 5–10 minutes before slicing.
- Garnish with fresh thyme if desired and serve with mashed potatoes, roasted vegetables, or a simple salad.
Tips for the Best French Onion Meatloaf
- Caramelize Onions Slowly: Low and slow cooking brings out their natural sweetness.
- Use 80/20 Ground Beef: Ensures juiciness without excess fat.
- Don’t Overmix: Overworking the meat can make the loaf dense.
- Rest Before Slicing: Helps the meatloaf hold together and keeps it moist.
- Extra Flavor: Add a splash of balsamic vinegar to the onions for a subtle tang.
Variations to Try
- Cheesy Surprise: Stuff the center with additional cheese for a gooey interior.
- Mushroom Lovers: Add sautéed mushrooms to the meat mixture for extra umami.
- Low-Carb Version: Skip breadcrumbs or use almond flour instead.
- Turkey Version: Substitute ground turkey for a lighter alternative.
- Glazed Top: Spread a layer of caramelized onion jam or ketchup mixed with brown sugar over the meatloaf for a sweet-savory glaze.
