First Step: Gather and prepare all ingredients by finely chopping onions, mincing garlic, and measuring out spices to streamline the cooking process.

Second Step: Heat olive oil over medium heat in a large skillet or saucepan. Add chopped onions and garlic, sautéing until translucent and fragrant, about 3-5 minutes.

Third Step: Add ground beef or preferred protein alternative, breaking it up with a spatula. Cook until browned thoroughly, approximately 7-10 minutes, ensuring no pink remains.

Fourth Step: Pour in dry red wine if using, allowing it to simmer for 3-4 minutes to reduce slightly and concentrate flavors.

Fifth Step: Stir in crushed tomatoes, dried oregano, salt, and pepper. Bring the mixture to a gentle simmer.

Sixth Step: Lower heat and add milk or suitable substitute, stirring well to combine. Let the sauce cook slowly for 45 minutes to an hour, stirring occasionally to prevent sticking.

Seventh Step: Taste and adjust seasonings as needed. For dietary adaptations, incorporate vegan substitutes at the protein step or adjust seasoning to enhance flavors accordingly.

Final Step: Serve the bolognese sauce over your choice of pasta or vegetables. Garnish with fresh herbs or grated cheese as preferred, enjoying the rich and satisfying dish.
