I'm not a fan of store-bought croutons because they can be so hard and not very flavorful. I made this recipe and decided this will be my go-to crouton recipe. Depending on how large your bread slices are you may want to make a recipe and a half of the butter/garlic mixture.
6 slices bread, trim crusts, cube (let bread sit out a few hours or overnight)
3 TBS melted butter
1 tsp garlic powder
1 tsp dried parsley
Preheat oven to 300 degrees. In a bowl, mix together the melted butter, garlic powder, parsley and salt. Add the bread cubes. Toss until well coated.
Spread onto a rimmed cookie sheet or a 9x13 pan.
Bake for 15 to 25 minutes or until golden brown and crunchy. Stir a few times during baking.
