Quick Overview
This French Onion Meatloaf is easy to assemble and packed with texture: soft, juicy meat interlaced with sweet onions and melted Gruyère. Preparation is straightforward—caramelize onions, mix, shape, and bake. The standout elements are the creamy, reduced onion broth and the cheese-studded interior. Prep time is about 25 minutes active, with 1 hour baking, total time roughly 1 hour 30 minutes including resting.
Ingredients
- 2 lbs Ground Beef, room temperature
- 2 Large Onions, thinly sliced
- 2 tbsp Butter, for cooking onions
- 1 tbsp Olive Oil, for cooking onions
- 1 cup Beef Broth
- 1/2 cup Breadcrumbs, plain
- 1/2 cup Gruyère Cheese, grated
- 2 Eggs, lightly beaten
- 2 cloves Garlic, minced
- 1 tbsp Worcestershire Sauce
- 1 tsp Dried Thyme
- Salt & Pepper, to taste
Directions
- Preheat oven to 375°F (190°C). Grease a loaf pan or baking dish and set aside.
- In a large skillet, heat 2 tbsp butter and 1 tbsp olive oil over medium heat. Add the thinly sliced onions and cook, stirring occasionally, for 20 to 25 minutes until deeply golden and caramelized—don’t rush this step; it builds the flavor.
- When the onions are caramelized, pour in 1 cup beef broth and increase heat slightly to let it reduce by half, about 5 to 7 minutes. Remove from heat and set aside to cool slightly.
- In a large bowl, combine 2 lbs ground beef, 1/2 cup breadcrumbs, 1/2 cup grated Gruyère, 2 eggs, 2 minced garlic cloves, 1 tbsp Worcestershire sauce, 1 tsp dried thyme, and salt and pepper to taste. Mix gently with your hands or a fork until just combined—overworking makes the loaf dense.
- Fold the cooled onion mixture into the beef mixture, ensuring even distribution without compacting the meat too much.
- Shape the mixture into a loaf and place it in your prepared greased baking dish, smoothing the top gently. If you like, add a little extra grated Gruyère on top for a golden finish.
- Bake in the preheated oven for about 1 hour, or until an instant-read thermometer inserted into the center reads 160°F (71°C).
- Remove the meatloaf and let it rest for 10 minutes before slicing. This helps the juices redistribute so slices hold together neatly. Serve warm and enjoy!
What to Serve With:
- Creamy mashed potatoes or buttered egg noodles to soak up the flavorful juices.
- A simple green salad with a tangy vinaigrette to cut through the richness.
- Roasted Brussels sprouts or green beans for a crisp, savory side.
- Crusty bread or baguette if you want something to mop up every last bit.
- For drinks, try a light red wine like Pinot Noir or a crisp apple cider for a non-alcoholic option.
Top Tips for Perfecting:
- Don’t rush the onions: Proper caramelization takes time but rewards you with deep, sweet flavor.
- Temperature matters: Let ground beef sit at room temperature for 15 minutes before mixing so it cooks evenly.
- Avoid overmixing: Combine ingredients until just incorporated to keep the meatloaf tender.
- Cheese swap: If Gruyère isn’t available, Swiss or fontina are great substitutes.
- For a crisp top: broil for 1–2 minutes at the end of baking to brown the cheese—watch closely to avoid burning.
- Flavor boost: Add a tablespoon of Dijon mustard to the mix for extra depth.
- Common mistake: Adding too much liquid to the meat mixture. Use the reduced broth from the onions sparingly—if it’s very wet, let it cool and thicken slightly before adding.
Storing and Reheating Tips:
- Refrigeration: Store leftovers in an airtight container for up to 3–4 days.
- Freezing: Slice the cooled meatloaf, wrap portions tightly in plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating on the stovetop: Place slices in a skillet with a splash of broth and warm over medium-low heat until heated through to retain moisture.
- Reheating in the oven: Preheat to 325°F (160°C), place slices in a baking dish with a few tablespoons of broth, cover with foil, and bake for 15–20 minutes until warmed.
- Microwave: For quick reheating, cover and microwave slices in 30-second intervals until hot, but expect less crisp texture.
FAQs
What type of ground beef is best for meatloaf?
Use 80/20 ground beef (20% fat) for the best balance of flavor and moisture. Leaner beef can dry out the loaf.
Can I make this meatloaf ahead of time?
Yes. Assemble the loaf, cover, and refrigerate up to 24 hours before baking. Allow it to sit at room temperature for 15 minutes before roasting.
Can I substitute the Gruyère cheese?
Absolutely—Swiss, fontina, or a mild cheddar will work well if Gruyère is unavailable.
Is there a low-sodium option for this recipe?
Use low-sodium beef broth and reduce added salt, relying on Worcestershire sauce and thyme for flavor.
Can I bake this in a slow cooker?
Yes, you can adapt it for a slow cooker—shape the loaf to fit and cook on low for 4–6 hours. For a slow-cooker method, consider a dedicated slow-cooker recipe to adjust liquid and timing precisely.
How do I know when the meatloaf is done?
The safest method is an instant-read thermometer: the center should reach 160°F (71°C).
