What You Need to Toast Walnuts
- Walnuts (shelled and halves or pieces)
- Baking sheet or oven tray
- Oven
- Spatula or spoon
- Optional: Parchment paper
Step-by-Step Guide to Toast Walnuts in the Oven
Step 1: Preheat The Oven
Set your oven to 350°F (175°C). Let it warm up fully before you put the walnuts inside. This helps toast them evenly.
Step 2: Prepare The Baking Sheet
Put parchment paper on the baking sheet. This stops the walnuts from sticking. If you do not have parchment paper, you can use the baking sheet directly. Just be ready to watch them carefully.
Step 3: Spread Walnuts On The Tray
Place the walnuts in one layer on the baking sheet. Spread them out evenly. Do not pile them up. This helps every walnut toast well.
Step 4: Toast The Walnuts
Put the baking sheet in the oven. Toast the walnuts for 5 to 10 minutes. Check them after 5 minutes. Stir or shake the tray gently to move the walnuts. This helps them toast evenly.
Step 5: Watch Closely
Walnuts can burn quickly. They turn from golden brown to burnt fast. Watch them closely in the last few minutes. When you smell a nutty aroma, they are ready.
Step 6: Cool The Walnuts
Take the walnuts out of the oven. Let them cool on the baking sheet or in a bowl. They get crunchier as they cool. Do not put hot walnuts in a closed container. Wait until they are cool.
