Any desired garnishessuch as: sun dried tomatoes, chopped basil, etc.
Bring a large pot of water to a boil and add pasta. Boil according to package directions.
While pasta is boiling, heat olive oil in a small fry pan over medium heat. Add minced garlic and heat, while stirring constantly, for a few minutes. (If garlic turns green, don't be alarmed, it just means it wasn't fully ripe). Add butter to garlic/oil and melt completely.
When pasta is done, drain well and pour into serving bowl(s). Pour garlic butter over pasta. Give a gentle toss. Top with garnishes or serve plain.
If using garlic powder, you can omit the olive oil as well. Simply melt butter over the hot pasta and sprinkle with garlic powder.
