Creating Meatloaf with Mushroom Gravy can be smooth sailing if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). This ensures an even cooking temperature for your meatloaf.

2. Prepare the Meatloaf Mixture: In a large mixing bowl, combine the ground beef, breadcrumbs, egg, chopped onion, minced garlic, Worcestershire sauce, thyme, salt, pepper, and milk.

3. Mix Until Combined: Using your hands or a spatula, mix the ingredients just until combined. Be careful not to overmix, as this can lead to a tougher meatloaf.

4. Shape the Meatloaf: Transfer the mixture to a greased loaf pan. Form it into a loaf shape, ensuring the top is slightly rounded for even cooking.

5. Bake: Place the loaf pan in the preheated oven and bake for approximately 1 hour or until the internal temperature reaches 160°F (70°C).

6. Rest the Meatloaf: Once cooked, remove from the oven and let it rest for about 10 minutes. This allows juices to redistribute for a tender bite.

7. Prepare the Gravy: While the meatloaf is resting, melt butter in a skillet over medium heat. Add the sliced mushrooms and sauté until they are soft and browned, about 5-7 minutes.

8. Make the Roux: Sprinkle the flour over the mushrooms, stirring continuously until the flour is absorbed, about 1-2 minutes.

9. Add Beef Stock: Gradually whisk in the beef stock. Continue to stir until the gravy thickens, about 3-5 minutes. Season with salt and pepper to taste.

10. Slice the Meatloaf: After resting, slice the meatloaf into even portions using a sharp knife.

11. Serve with Gravy: Spoon the mushroom gravy over the sliced meatloaf, allowing it to soak in for added flavor.

These straightforward steps will result in a succulent Meatloaf with Mushroom Gravy that will impress your family and friends.
