Place almonds in a dry skillet. Don't add any oil.
Heat over medium to medium-low heat.
Move the almonds around every few seconds. Just slide the pan around and give it a little shake to flip the almonds or use a heat-proof silicone spatula. Once the pan is warm, this takes just 1-2 minutes.
As soon as the almonds are brown, remove them from the pan onto a plate.
Oven Method
Place almonds on a baking sheet. I like to use parchment because it makes removing the almonds easy.
Put baking sheet in a preheated 350° oven for 6-10 minutes, flipping halfway through cooking.
Once the almonds are brown, remove them from the oven and place almonds on a clean plate
Notes
Any amount of almonds may be toasted. I often toast just the amount I need for a recipe.
Always stay near your almonds while they are toasting. They can go from brown to burnt in no time at all.
Actual time will vary depending on your stove, your pan, your oven, and the amount of almonds you are toasting.
Use of parchment paper in the oven is optional.
Rely on your nose, instead of the timer. You'll begin to smell the almonds as they begin to brown.
Remove the almonds from the pan or baking sheet as soon as they are the desired color. Otherwise, they will continue to brown in the hot pan.
