Ingredients
  

For the Meatloaf:
  • 1½ lbs ground beef 80/20 recommended
  • 8 oz mushrooms finely chopped
  • 1 small onion finely diced
  • 2 cloves garlic minced
  • 1 cup breadcrumbs
  • 2 large eggs
  • 1/2 cup milk
  • 1 tbsp Worcestershire sauce
  • 1 tsp dried thyme or Italian seasoning
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1 tbsp olive oil for sautéing
  • For the Glaze:
  • 1/3 cup ketchup
  • 1 tbsp brown sugar
  • 1 tsp Dijon mustard optional, for tang

Equipment

  • Loaf pan or baking sheet
  • Skillet
  • Mixing bowls:
  • Spatula or Wooden Spoon:

Method
 

Preheat Oven
  1. Preheat your oven to 375°F (190°C). Line a loaf pan with parchment paper or lightly grease it.
Sauté Vegetables
  1. In a skillet, heat olive oil over medium heat. Add mushrooms, onion, and garlic. Cook for 5–6 minutes, until softened and most of the liquid has evaporated. Let cool slightly.
Mix the Meatloaf
  1. In a large bowl, combine ground beef, sautéed vegetables, breadcrumbs, eggs, milk, Worcestershire sauce, thyme, salt, and pepper. Mix gently with your hands until just combined — do not overmix.
Shape & Add Glaze
  1. Press the mixture into the prepared loaf pan or shape it into a freeform loaf on a parchment-lined baking sheet. Stir together ketchup, brown sugar, and Dijon mustard, then spread half over the top of the loaf.
Bake
  1. Bake for 45 minutes, then remove from the oven and brush with the remaining glaze. Return to the oven for another 10–15 minutes, or until the internal temperature reaches 160°F (71°C).
Rest & Serve
  1. Let the meatloaf rest for 10 minutes before slicing. Serve warm with mashed potatoes, gravy, or roasted vegetables.

Notes

Make it extra moist: Mix in ¼ cup grated Parmesan or a few tablespoons of sour cream.
Vegetarian option: Substitute beef with lentils or plant-based meat and skip the eggs for a meat-free version.
Storage: Keeps in the fridge for up to 4 days or freeze slices for up to 3 months.
