• 1 cup breadcrumbs (plain or Italian style)
• ¾ cup milk (or broth for dairy-free option)
• 1 large onion, thinly sliced
• 2 cloves garlic, minced
• 2 eggs, lightly beaten
• 2 tbsp Worcestershire sauce
• 1 tsp salt
• ½ tsp black pepper
• 1 tsp dried thyme or 2 tsp fresh, chopped

For the Glaze:

Simple Cooking Directions

1. Caramelize the onions slowly.
2. Mix meatloaf ingredients and fold in caramelized onions.
3. Shape into a loaf and spread glaze on top.
4. Bake until fully cooked and serve.

Step-by-Step Preparation Method

1. Caramelize Onions: Heat 1 tbsp olive oil or butter in a skillet over medium-low heat. Add sliced onions with a pinch of salt. Cook, stirring occasionally, for 15–20 minutes until golden brown and sweet. Set aside to cool slightly.
2. Preheat Oven: Preheat oven to 375°F (190°C). Grease a loaf pan or line a baking sheet with parchment paper.
3. Soak Breadcrumbs: In a small bowl, combine breadcrumbs and milk. Let sit 5 minutes until softened.
4. Mix Meatloaf: In a large bowl, combine ground beef, eggs, garlic, Worcestershire sauce, thyme, parsley, salt, and pepper. Add soaked breadcrumbs and caramelized onions. Mix gently until just combined (avoid overmixing).
5. Shape Loaf: Form mixture into a loaf shape in the prepared pan.
6. Prepare Glaze: In a small bowl, mix ketchup, brown sugar, Dijon mustard, and apple cider vinegar. Spread half the glaze over the top of the meatloaf.
7. Bake: Bake for 45 minutes. Remove from oven, spread remaining glaze, and bake another 10–15 minutes until internal temperature reaches 160°F (71°C).
8. Rest: Let meatloaf rest for 10 minutes before slicing to retain juices.

How to Serve

• Pair with mashed potatoes, roasted vegetables, or green beans.
• Slice and serve in sandwiches the next day.
• Garnish with fresh parsley for presentation.

Additional Recipe Tips

• Caramelize onions slowly for maximum sweetness and depth.
