Prepare all the necessary ingredients. Wash the garlic and onion thoroughly, then finely chop them. Cut the smoked beef into small squares.

Boil the spaghetti in salted water to give it flavor. Stir the spaghetti to prevent it from sticking together and cook until al dente. Once cooked, drain it.

Melt the butter, sauté the garlic and onion until fragrant. Once aromatic, add the smoked beef and stir until cooked. Then add the flour, stirring until it clumps and starts to brown.

Pour the milk into the pan, add all the seasonings (salt, pepper, oregano). Once it starts to boil, reduce the heat, and add the grated cheese. Stir continuously until the cheese is fully melted.

Taste and adjust the seasoning if necessary. Once the taste is right, add the spaghetti and stir until the sauce evenly coats the spaghetti. Turn off the heat and serve on a plate. Enjoy while warm. Happy cooking. 😁
