This rich comforting Vegan Grilled Cheese with Caramelized Onions and Red Pepper is loaded with sweet and savory flavors.
If you have been following me for a while you may have noticed that I am a little obsessed with caramelized onions. One of my favorite ways to use them is in a dip, but I also love them in pasta, vegan tofu quiche, and mushroom sliders.
So today I decided to make Vegan Grilled Cheese with Caramelized Onions and Red Pepper. There is something about caramelized onions that takes everything to a whole new level.
They add a sweet, rich taste to whatever you put them in. If you are looking to take your vegan grilled cheese up a notch, caramelized onions are the way to go.
Some roasted red pepper recipes to try are my Onion and Roasted Red Pepper Focaccia Sandwich and my Tofu Ricotta and Red Pepper Dip. A caramelized onion recipe to try is my Onion Fritters recipe.
Other grilled cheese recipes to try are my Vegan Pesto Cheese Sandwich and my Vegan Pizza Grilled Cheese recipe.
Maple Mustard Tofu is also good in a sandwich.

💭 Tips
- When making caramelized onion, slow and steady wins the race. For caramelized onions, you need some patience. It takes a good 20 minutes to get nicely browned onions - longer if you're using more onions.
- If they take start to stick add a little water, like a quarter of a cup or so.
- Balsamic vinegar adds a wonderful flavor. I always add a couple of splashes near or at the end of the cooking time.
