🌟 Why This Recipe Works

🔪 Step-by-Step Instructions
🧈 Step 1: Caramelize the Onions
-
In a large skillet over medium heat, melt 2 tbsp butter with 1 tbsp olive oil.
-
Add the thinly sliced onions and stir to coat.
-
Sprinkle with 1/2 tsp sugar and 1/4 tsp salt. This helps the onions brown.
-
Cook over medium-low heat, stirring frequently, for 25–30 minutes, until the onions are golden brown and caramelized.
-
Optional: Add 1 tbsp balsamic vinegar during the last 5 minutes to enhance depth.
-
Set aside to cool.
Pro Tip: Don’t rush the onions. Slow cooking is key to rich, sweet flavor.
🧂 Step 2: Prepare the Meatloaf Mixture
-
In a large bowl, combine:
-
2 lbs ground beef
-
1/2 lb ground pork (optional but recommended)
-
1 cup caramelized onions
-
2 minced garlic cloves
-
1 cup breadcrumbs
-
1/2 cup milk
-
2 eggs
-
2 tsp Worcestershire sauce
-
1 tbsp Dijon mustard
-
1 tsp salt
-
1/2 tsp pepper
-
1/2 tsp dried thyme
-
1/4 tsp ground sage (optional)
-
-
Gently mix with your hands or a large spoon until combined. Do not overmix.
Why breadcrumbs and milk? They form a panade, which keeps the meatloaf moist and tender.
🧀 Step 3: Add the Cheese
-
Fold in 1 cup shredded Gruyère or Swiss cheese into the meat mixture.
-
Alternatively, press half the meat mixture into the loaf pan, add a cheese layer, and top with the remaining meat to create a cheesy center.
🥩 Step 4: Form and Bake
-
Preheat your oven to 350°F (175°C).
-
Line a loaf pan or baking sheet with parchment paper.
-
Shape the meat mixture into a loaf and place into the prepared pan.
-
Bake for 55–65 minutes, or until internal temperature reaches 160°F (71°C).
-
In the last 5–10 minutes, sprinkle the remaining 1/2 cup shredded cheese over the top. Return to oven and bake until cheese is melted and bubbly.
🍷 Optional: Make the French Onion-Style Gravy
-
In a small saucepan, melt 1 tbsp butter over medium heat.
-
Whisk in 1 tbsp flour and cook for 1–2 minutes to form a roux.
-
Slowly add 1/2 cup beef broth, whisking constantly to prevent lumps.
-
Add 1 tsp Worcestershire and a splash of white wine or vinegar.
-
Simmer for 3–4 minutes until slightly thickened. Drizzle over sliced meatloaf or serve on the side.
⏲ Step 5: Rest and Serve
-
Let the meatloaf rest for 10 minutes before slicing.
-
Slice into thick pieces and serve with mashed potatoes, roasted vegetables, or buttered green beans.
Resting tip: This helps redistribute juices and keeps your meatloaf moist.
🧊 Storage and Reheating
-
Refrigerate: Store in an airtight container for up to 4 days.
-
Freeze: Wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
-
Reheat: Warm slices in the oven at 300°F or microwave in 30-second bursts.
