How to Make

Quick Overview

This French Onion Meatloaf is straightforward: caramelize onions slowly, reduce beef broth to concentrate flavor, mix into ground beef with cheese and breadcrumbs, shape into a loaf, and bake. The texture is tender and juicy thanks to eggs and breadcrumbs; the standout element is the rich caramelized onion reduction that keeps every slice luscious. Prep time is about 30 minutes (most of that for caramelizing onions), and baking takes roughly 1 hour — total time about 1 hour 30 minutes.

Ingredients

2 lbs Ground Beef (80/20 recommended for juiciness)
2 Large Onions, thinly sliced
2 tbsp Butter (unsalted, for caramelizing onions)
1 tbsp Olive Oil (to prevent butter from burning)
1 cup Beef Broth (low-sodium preferred)
1/2 cup Breadcrumbs (plain or seasoned)
1/2 cup Gruyere Cheese, grated (packed)
2 Eggs (large, room temperature)
2 cloves Garlic, minced
1 tbsp Worcestershire Sauce
1 tsp Dried Thyme
Salt & Pepper, to taste

Directions

Preheat your oven to 375°F (190°C). Lightly grease a baking dish or line with parchment for easier cleanup.
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 they are deeply golden and caramelized. Take your time — the sugar in the onions needs to develop slowly for the best flavor.
Pour in 1 cup beef broth and increase the heat slightly to bring to a simmer. Let the broth reduce by about half, stirring occasionally, until it’s a rich, syrupy mixture. This should take 6 to 8 minutes. Remove from heat and set aside to cool slightly.
In a large mixing bowl, combine 2 lbs ground beef, 1/2 cup breadcrumbs, 1/2 cup grated Gruyère, 2 eggs, 2 cloves minced garlic, 1 tbsp Worcestershire sauce, 1 tsp dried thyme, and salt and pepper to taste. Use your hands or a spoon to gently mix — don’t overwork the meat.
Once the onion-broth mixture is cool enough to handle, fold it into the meat mixture until evenly distributed. The cooled onions add moisture and intense flavor without making the loaf soggy.
Shape the mixture into a loaf shape with your hands and place it into the greased baking dish. Smooth the top so it bakes evenly. If desired, top with a few extra slices of Gruyère for a cheesy crust.
Bake for about 1 hour, or until the internal temperature reaches 160°F (71°C) measured in the center. If the top is browning too quickly, loosely tent with foil.
Let the meatloaf rest for about 10 minutes before slicing — this helps the juices redistribute and keeps slices neat. Serve warm and enjoy!

What to Serve With

Creamy mashed potatoes or roasted garlic mashed potatoes for ultimate comfort.
Steamed green beans or sautéed Brussels sprouts to add brightness and texture.
A crisp green salad with a tangy vinaigrette to cut the richness.
Warm dinner rolls or buttered crusty bread to soak up any juices.
A glass of medium-bodied red wine or a cold ale complements the savory flavors nicely.

Top Tips for Perfecting

Caramelize onions low and slow: Rushing this step with high heat creates bitter edges instead of sweet depth.
Use 80/20 ground beef: The fat helps keep the loaf moist. If you prefer leaner meat, add a tablespoon of olive oil or a splash of milk.
Cool the onion mixture before mixing: Hot onions can melt the cheese and change the texture of the loaf.
Add a glaze: Brush ketchup mixed with a little brown sugar and Worcestershire during the last 15 minutes of baking for a sweet-savory finish.
Don’t overmix the meat: Overworking makes the loaf dense. Combine ingredients until just mixed.
Test doneness with a thermometer: 160°F internal temp ensures safety while keeping juices intact.

Storing and Reheating Tips

Refrigeration: Cool leftovers to room temperature, then store in an airtight container in the fridge for up to 3–4 days.
Freezing: Wrap cooled slices tightly in plastic wrap and place in a freezer bag or container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating: Reheat slices in a 350°F oven covered with foil for 10–15 minutes until warmed through. For single slices, microwave on medium power for 60–90 seconds, checking to avoid drying out. Add a splash of beef broth before reheating to restore moisture if needed.

FAQs

Can I use ground turkey or chicken instead of beef?
Yes — you can substitute ground turkey or chicken, but leaner meats are drier. Add 1–2 tablespoons of olive oil or a half cup of grated vegetables (like zucchini or carrots) to keep the loaf moist.

Do I have to use Gruyère cheese?
No. Gruyère adds a nutty, creamy note, but Swiss or cheddar are acceptable substitutes. For a stronger flavor, try a small amount of sharp cheddar.

Can I make this ahead of time?
Absolutely. Assemble the meatloaf, cover, and refrigerate for up to 24 hours before baking. Let it sit at room temperature for 20 minutes before placing in the oven.

How do I prevent the meatloaf from falling apart when slicing?
Let it rest for at least 10 minutes after baking. Resting firms the loaf and keeps slices intact. Use a sharp knife and slice gently.

Is there a slow-cooker or crock pot version?
Yes — you can slow-cook this loaf; transfer the shaped loaf to a greased slow cooker and cook on low for 4–6 hours. For a tested slow-cooker approach, consult trusted recipes to adjust liquid and timing.
