Melt 3 tbsp of butter in a pot over medium heat.
Add garlic and all seasonings, stirring until the butter foams and smells fragrant.
Pour in chicken broth, half and half, soy sauce, and the bouillon cube. Bring to a boil.
Add the dry pasta. Simmer uncovered, stirring occasionally to prevent sticking, until the pasta is tender and the liquid has reduced into a thick sauce.
Reduce heat to low. Gradually stir in the Parmesan cheese until smooth.
Remove from heat. Stir in the lemon juice and the remaining 1 tbsp of butter.
Cover for 1 minute to let everything meld.
Serve warm.
