🍳 Step-by-Step Instructions
Step 1: Caramelize the Onions
This is where the magic starts.
- In a large skillet, heat olive oil over medium heat.
- Add the sliced onions and cook, stirring often, for 25–30 minutes until deep golden and caramelized.
- Add minced garlic, sauté for 1–2 minutes more.
- Deglaze with beef broth and Worcestershire sauce, scraping up browned bits.
- Simmer until most of the liquid has reduced, then remove from heat.
Step 2: Prepare the Meatloaf Mix
- Preheat your oven to 375°F (190°C).
- In a large bowl, combine:
- Ground beef
- Half of the caramelized onion mixture
- Eggs, breadcrumbs, thyme, Dijon, salt, and pepper
- Mix gently until combined — avoid over-mixing to keep the meatloaf tender.
Step 3: Shape and Bake
- Transfer meat mixture to a greased 9x5-inch loaf pan or form a loaf shape on a lined baking sheet.
- Bake uncovered for 35 minutes.
Step 4: Make the Cheese Sauce
While the meatloaf is baking:
- In a saucepan, melt butter over medium heat.
- Whisk in flour and cook for 1–2 minutes to create a roux.
- Slowly whisk in milk, stirring until smooth.
- Add mozzarella and Gruyère, stirring until melted and creamy.
- Season with a pinch of salt and pepper.
Step 5: Add the Toppings and Finish Baking
- After 35 minutes of baking, remove the meatloaf.
- Top with the remaining caramelized onions.
- Pour the cheese sauce over the top.
- Return to oven and bake for 15–20 more minutes, until the cheese is bubbling and lightly golden.
