Note: The full list of this recipe ingredients with their amounts and options are listed in the recipe card below.
- Olive oil -- this is my favorite oil but you can also use grapeseed oil, peanut oil, or vegetable oil.
- Onion -- yellow onions have a nice balance of astringency and sweet in their flavor, becoming sweeter the longer they cook.
- Garlic Powder -- if you want to use garlic cloves, add two minced cloves to the onion as it is cooking.
- Kosher Salt -- we prefer using Kosher rather than table sale in this recipe.
- Black Pepper -- freshly ground or restaurant grade pepper adds more flavor.
- Dried Basil
- Dried Thyme
- Half and Half Cream -- may use a combination of heavy cream and milk if you don't have half and half.
- Cornstarch -- this is what thickens the liquid.
- Panko Breadcrumbs -- may use regular breadcrumbs.
- Parmesan Cheese -- freshly grated is best.
- Butter -- you may use salted or unsalted.
- Fresh Parsley -- used as a garnish.
