Let’s dive into the details of how to create this delicious meal that combines simplicity with rich flavors.

Crafting the Perfect Beef Layer

To start, gather the ingredients for the beef layer. You will need:

• 450g (1 lb) ground beef
• 1 medium onion, diced finely
• 2 cloves garlic, minced
• 1 cup marinara or tomato sauce
• 1 tbsp tomato paste

Begin by sautéing the aromatics. In a large skillet or an oven-safe pot, heat the oil over medium heat. Add the diced onion and cook for about 4-5 minutes until softened. Then, add the minced garlic and cook for an additional 30 seconds, ensuring it becomes fragrant without burning.

Next, add the ground beef to the skillet. Break it apart as it cooks, allowing it to turn from pink to brown, which should take about 6 to 8 minutes. If using lean beef, drain any excess fat, then stir in the tomato paste for added flavor. After a minute, incorporate the marinara sauce and let the mixture simmer for 5-7 minutes. Season with salt, pepper, and a pinch of oregano or red pepper flakes to taste.
