Ingredients & Equipment
You’ll need the following ingredients and equipment to make this truffle French onion grilled cheese:
- Stainless steel pan
- Thick cut bread
- Yellow onion
- Truffle gruyere cheese
- Butter
- Olive oil
- Salt
- Blue cheese (optional)
Customize This Recipe!
There are a few different ways you can customize this recipe:
- Use your favorite cheese. The truffle gruyere is truly life-changing (in my opinion), but feel free to use any melty cheese of your choosing!
- Bread is your friend. Don't skimp on the bread here - go for a crusty sourdough or a thick cut of any bakery loaf to get the best overall grilled cheese experience.
Kitchen Tips:
- Utilize mise en place! Make sure you have all of your ingredients prepped and ready before you begin making this recipe - it will help save you time and keep you organized.
- Microwave if needed. The heat from your onions should melt the cheese right away, but if it needs a bit of help, you can microwave the bowl of onions and cheese for ten seconds to do the trick.
- Deglaze your pan. While caramelizing your onions, if the bottom of your pan is getting sticky at all, add a bit of water to the pan and let it lift up all those yummy brown bits - the onions will reabsorb everything, especially the flavor!

Truffle French Onion Grilled Cheese
Ingredients
- 2 tablespoon olive oil
- 1 yellow onion sliced lengthwise
- 1 pinch salt
- 2 oz truffle gruyere cheese shredded
- 1 tablespoon butter
- 2 slices sourdough or thick-cut bread
Instructions
- While slicing the onions, heat the olive oil in a stainless steel pan on medium-low heat for a couple minutes.
- Add onion slices to the pan and lower heat slightly. Season with a hearty pinch of salt.
- Keep onions cooking over medium-low heat for about 45 minutes until they reach a deep golden brown color. Stir every few minutes to prevent sticking. If the onions are getting brown or black/burned too quickly, lower your heat.
- When the onions are done, put them into a bowl with the shredded cheese and let them sit until the onions melt the cheese. You can also microwave the bowl for a few seconds if the cheese isn't melting enough just from the heat of the onions.
- Butter both sides of the bread slices, grease the pan a bit more, and assemble the grilled cheese in the pan. Heat on both sides for a couple minutes each, until the bread is toasted and golden brown.
- Remove from heat and serve with a side of blue cheese for extra flavor!
