What You’ll Gather

- 2 tablespoons unsalted butter
- 1 pinch of salt
- 1/8 cup water
- 2 tablespoons balsamic vinegar
- 4 slices of whole wheat bread (sourdough or whole-grain are very good too)
- 2 tablespoons mayonnaise (1 1/2 teaspoons per slice)
- 1 cup reduced-fat cheddar cheese
Kitchen Gear Checklist
- Skillet or frying pan – for cooking the onions and grilling the sandwich.

Grilled Cheese With Caramelized Onions Made Stepwise
Step 1: Prepare the Onions
Start by peeling and slicing the yellow onions into thin rings. This will help them caramelize evenly and blend beautifully with the cheese.
Step 2: Caramelize the Onions
In a skillet, melt the unsalted butter over medium heat. Add the sliced onions and a pinch of salt. Stir to coat the onions in the butter.
Step 3: Add Water and Balsamic Vinegar
Once the onions start to soften (after about 5 minutes), add the water and balsamic vinegar. Continue cooking, stirring occasionally, for another 15-20 minutes until the onions are golden brown and caramelized.
Step 4: Assemble the Sandwich
While the onions are caramelizing, spread mayonnaise on one side of each slice of whole wheat bread. Flip the slices over so the mayonnaise side is down. On two of the slices, layer the reduced-fat cheddar cheese and then the caramelized onions. Top with the remaining slices of bread, mayonnaise side up.
Step 5: Grill the Sandwich
In the same skillet used for the onions, place the sandwiches over medium heat. Grill for about 3-4 minutes on each side or until the bread is golden brown and the cheese is melted. You may want to press down gently with the spatula for even cooking.
Step 6: Serve and Enjoy
Once golden and crispy, remove the sandwiches from the skillet. Cut them in half, serve immediately, and enjoy the melty goodness of your Grilled Cheese With Caramelized Onions!
Vegan & Vegetarian Swaps
- For a vegan version, replace the butter with vegan butter and use a plant-based cheese alternative.
- Instead of mayonnaise, you can use a vegan mayo or even avocado spread for added creaminess.
- For added protein, consider adding sliced tomatoes or spinach to the sandwich.
Watch Outs & How to Fix
Cooking caramelized onions can be tricky. If they start to burn, reduce the heat and add a splash of water to deglaze the pan. This will help lift any stuck bits and prevent burning.
- Make sure to keep stirring the onions every few minutes to ensure even cooking.
- If your grilled cheese isn’t browning, the heat may be too low. Increase it slightly to achieve that golden crust.
- If the cheese isn’t melting, cover the skillet for a minute or two to create steam, which will help melt the cheese faster.
Shelf Life & Storage
Grilled Cheese With Caramelized Onions is best enjoyed fresh, but you can store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place the sandwich in a skillet over medium heat until warmed through, or use a toaster oven for a crispy finish.
Ask & Learn
Can I use any type of cheese for this recipe?
Yes! While reduced-fat cheddar is a great choice, you can also experiment with mozzarella, gouda, or even a spicy pepper jack for a kick.
How do I know when my onions are caramelized?
Onions are caramelized when they turn a deep golden brown and have a sweet, rich flavor. This process usually takes about 20-30 minutes over medium heat.
Can I make the caramelized onions ahead of time?
Absolutely! You can caramelize the onions a day in advance and store them in the refrigerator. Just reheat them before assembling your sandwich.
What bread works best for grilled cheese?
While whole wheat bread is a healthier option, sourdough, rye, or even a good quality white bread can work wonderfully for grilled cheese sandwiches.
