I have found that this recipe does not come out the same if you use frozen or fresh green beans.  I've found it tastes best with canned green beans.

Helpful Tips for All Recipes
  • When a recipe call for House Seasoning Blend, you can find the recipe on www.itisakeeper.com. Simply search for "House Seasoning Blend" or you can substitute salt and pepper to taste.  
  • I always use unsalted butter in my recipes.
  • I always use a meat thermometor to test for doneness when cooking meat.
  • When a recipe is made in the oven, it should be pre-heated to the temperature in the recipe, unless otherwise noted.
