Bring a large pot of salted water to a boil and cook pasta (I used penne) according to package directions (for al dente cook 1-2 minutes less than than package directions).
Heat a large saute pan over medium heat and saute the mushrooms for 5 minutes or until starting to turn golden.
Add garlic and continue to cook one minute.
Drain water off pasta (reserving 1/4 cup pasta water). Return the pasta to the large pot and toss with reserved pasta water and olive oil.
Add mushrooms to the pasta stirring to combine and place in a large serving dish.
