🍽️ Introduction
This French Onion Meatloaf is a gourmet upgrade to your everyday meatloaf. Inspired by the rich flavors of French onion soup, it features caramelized onions, Gruyère or Swiss cheese, and herbs baked right into a juicy meat mixture. It’s topped with more melty cheese and baked until golden and bubbling. Perfect for a cozy family dinner or a meal prep superstar that tastes even better the next day.
🛒 Ingredients
For the Caramelized Onions:
- 2 large yellow onions, thinly sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 1 tsp sugar (optional, to speed caramelization)
- Pinch of salt
For the Meatloaf:
- 1.5 lbs (680 g) ground beef (80/20 is ideal)
- ½ cup caramelized onions (from above)
- 1 cup shredded Gruyère or Swiss cheese
- ½ cup plain breadcrumbs
- 2 eggs
- 2 tbsp Worcestershire sauce
- 1 tbsp Dijon mustard
- 1 tbsp fresh thyme leaves (or 1 tsp dried)
- 2 cloves garlic, minced
- ½ tsp salt
- ½ tsp black pepper
For the Topping:
- Remaining caramelized onions
- ¾ cup shredded Gruyère or Swiss cheese
- Optional garnish: Fresh thyme or parsley
👩🍳 Instructions & Method
Step 1: Caramelize the Onions
- In a large skillet over medium heat, melt the butter and olive oil.
- Add the sliced onions and a pinch of salt.
- Cook slowly for 25–30 minutes, stirring occasionally, until the onions are deep golden brown. Add a teaspoon of sugar about 15 minutes in to help them caramelize faster.
- Set aside to cool. Reserve about half for the topping.
Step 2: Prepare the Meatloaf Mixture
- Preheat your oven to 375°F (190°C).
- In a large mixing bowl, combine:
- Ground beef
- ½ cup caramelized onions
- 1 cup shredded cheese
- Breadcrumbs
- Eggs
- Worcestershire sauce
- Dijon mustard
- Thyme
- Minced garlic
- Salt and pepper
- Mix gently with your hands or a spatula until just combined. Do not overmix — that can make the meatloaf tough.
Step 3: Shape & Bake
- Line a baking sheet with parchment paper or foil, or use a loaf pan.
- Shape the meat mixture into a loaf shape (roughly 9×5 inches) or press it into the pan.
- Bake uncovered for 35 minutes.
Step 4: Add the Topping
- Remove from the oven and carefully top the loaf with:
- Remaining caramelized onions
- ¾ cup shredded cheese
- Return to oven and bake another 15–20 minutes, or until internal temperature reaches 160°F (71°C) and the cheese is melted and bubbly.
Step 5: Rest & Serve
- Let the meatloaf rest for 10 minutes before slicing — this helps the juices redistribute and gives you clean slices.
- Garnish with a little fresh thyme or parsley, if desired.
- Serve with mashed potatoes, roasted vegetables, or a green salad.
📝 Tips & Variations
- Cheese options: Gruyère gives the most classic French onion flavor, but Swiss or even provolone work well.
- Make it ahead: You can assemble the meatloaf a day in advance and refrigerate it before baking.
- Leftovers: Fantastic as a sandwich filling with extra onions and melted cheese.
