Ingredients

• Ground Beef: 1 ½ pounds, 80/20 blend, for juicy texture.
• Onions: 2 medium (about 2 cups), thinly sliced, for caramelized sweetness.
• Breadcrumbs: ¾ cup, plain or panko, for binding.
• Egg: 1 large, for structure.
• Milk: ½ cup, for moisture.
• Beef Broth: ¼ cup, low-sodium, for savory depth.
• Gruyère or Swiss Cheese: 1 cup, shredded, for melty topping.
• Garlic: 2 cloves, minced, for aroma.
• Thyme: 1 teaspoon, dried (or 2 teaspoons fresh), for herby flavor.
• Worcestershire Sauce: 1 tablespoon, for umami.
• Olive Oil: 1 tablespoon, for cooking onions.
• Butter: 1 tablespoon, for caramelizing onions.
• Salt: ¾ teaspoon, or to taste.
• Black Pepper: ½ teaspoon, for seasoning.
• Optional Add-Ins: ¼ cup chopped mushrooms for extra earthiness.
• Optional Glaze: Mix 2 tablespoons ketchup with 1 teaspoon brown sugar for a sweet-tangy top.
• Optional Side: Mashed potatoes, green beans, or a side salad.

Instructions

1. Prepare Your Ingredients (Mise en Place): Thinly slice onions, mince garlic, shred cheese, and measure breadcrumbs, milk, and broth. Preheat oven to 350°F (175°C). Line a baking sheet with parchment or lightly grease a 9×5-inch loaf pan.
2. Caramelize the Onions: Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-low heat. Add sliced onions and a pinch of salt. Cook, stirring occasionally, for 15-20 minutes until golden and soft. Add a splash of beef broth if they stick. Stir in garlic and thyme, cook for 1 minute, then set aside to cool slightly.
3. Mix the Meatloaf: In a large bowl, combine ground beef, breadcrumbs, egg, milk, Worcestershire sauce, ½ cup beef broth, ½ teaspoon salt, ½ teaspoon pepper, and half the caramelized onions (about 1 cup). Mix gently with your hands until just combined; avoid overmixing to keep the loaf tender.
4. Shape and Bake: Form the mixture into a loaf shape on the baking sheet or press into the loaf pan. If using glaze, spread ketchup-brown sugar mixture over the top. Bake for 50-60 minutes, until the internal temperature reaches 160°F (71°C).
5. Add Cheese and Onions: Remove meatloaf from oven. Top with remaining caramelized onions and shredded Gruyère. Return to oven for 5-7 minutes until cheese is melted and bubbly.
6. Serve: Let meatloaf rest for 10 minutes before slicing. Serve hot with mashed potatoes, green beans, or a side salad for a complete meal.
