In a large measuring cup with a spout, combine the beef broth, chicken broth, half-and-half, Worcestershire sauce, onion powder, garlic powder, dried oregano, dried basil, mustard powder, dried parsley, and smoked paprika.
Stir until fully combined, then set the sauce mixture aside.
Measure all remaining ingredients before beginning the cooking process.
Bring a large pot of salted water to a boil for the macaroni.
Lightly season the ground beef with salt and black pepper.
Heat a large skillet over medium-high heat.
Add the seasoned ground beef to the skillet.
Cook for approximately 8 minutes, breaking the beef apart as it browns, until fully cooked.
Remove the cooked beef from the skillet.
Drain any excess grease and set the beef aside.
In the same skillet, melt the unsalted butter over medium heat.
Add the all-purpose flour to the melted butter.
Stir continuously until a smooth mixture forms.
Cook for approximately 2 minutes, or until the mixture begins to turn lightly toasted in color.
Reduce the heat to medium-low.
Gradually add the prepared sauce mixture to the skillet in small increments, stirring continuously after each addition.
Continue stirring until the sauce is smooth and fully combined.
Add the half beef bouillon cube to the sauce.
Stir until the bouillon is fully dissolved.
Increase the heat slightly and bring the sauce to a gentle boil.
Reduce the heat and allow the sauce to simmer uncovered while preparing the macaroni.
Add the macaroni to the boiling salted water.
Cook according to package directions until just al dente.
Drain the cooked macaroni well and set aside.
Reduce the sauce heat to low.
Gradually add the grated cheddar cheese, stirring continuously until the cheese is fully melted and incorporated.
Return the cooked ground beef to the skillet.
Stir until the beef is evenly coated in the cheese sauce.
Add the cooked and drained macaroni to the skillet.
Stir thoroughly until the pasta is evenly coated with the sauce.
Allow the mixture to rest briefly if needed, as the sauce will thicken as the macaroni absorbs it.
Remove the skillet from the heat.
Serve immediately while warm and creamy.
