I saw this recipe on Pinterest last night (http://iowagirleats.com/2013/03/06/creamy-garlic-shells/) and had to try it.
It was delicious and very easy!
8 oz mini shells pasta
1 Tbsp olive oil
1 Tbsp butter
3 cloves garlic
2 Tbsp flour
3/4 cup chicken broth
3/4 cup milk
salt and pepper
1/4 tsp garlic powder
1/4 cup Parmesan cheese
2 tsp parsley
Cook mini shells until tender. Drain and set aside. In a medium pot, melt the butter with the olive oil on medium heat. Add the garlic. Cook the garlic (being careful not to burn) for about 30 seconds. Whisk in the flour. Let it cook for a minute.
While continuing to whisk, slowly add the chicken broth and milk. Keep whisking until the mixture is smooth. Add salt and pepper. (I did about 1 tsp of salt and 1/4 tsp pepper.)
Switch over to a wooden spoon. Continue stirring constantly for about 4-5 minutes, or until thickened. I turned up the heat a little bit.
When the sauce is thickened, remove from heat and add the Parmesan cheese, garlic powder, and parsley. When the cheese melts, add the cooked pasta. Stir and serve.
