This sweet potato grilled cheese sandwich takes a basic sandwich to the next level! With creamy Gruyère cheese, hearty slices of sweet potato, and a creamy aioli, this grilled cheese is an elevated classic!
If you’re bored with plain old grilled cheese sandwiches, this sweet potato grilled cheese is a great way to switch things up and squeeze in some vegetables into your meal.
How to Cook Sweet Potato Slices
There are three ways to cook the sweet potato slices before making this sandwich.
- Microwave Method – Add the sweet potato slices to a shallow bowl, with 1″ of water at the bottom. Microwave for 5-6 minutes, or until the sweet potato is soft.
- Stovetop Method – Place the sweet potato slices in a single layer in a large skillet. Add 1″ of water then cover and simmer for 8-10 minutes until softened. Add more water, if needed.
- Oven Method – Preheat oven to 350 degrees. Line a baking sheet with parchment paper. Place the sliced sweet potato in a single layer on the baking sheet. Bake for 10 minutes then flip and continue to bake for 5 minutes or until softened.
The Best Bread for Grilled Cheese
I like to use sourdough bread. Trader Joe’s sells a great sourdough loaf that is sliced into 1/2″ slices which are perfect for a sandwich like this! You can use any bread you like, including gluten-free bread, but I recommend something with a hearty, chewy crust.
How to Massage Kale
Before adding the kale to this sandwich, it’s important to massage it. Once the kale has been washed, remove the tough stem. Tear the large leaves into quarters, then use your hands so squeeze the kale leaves. They’ll soften and turn darker in color. This results in a better texture and makes it easier to chew and digest!
Substitution Ideas
- Feel free to swap in slices of butternut squash in place of sweet potato. The cooking methods for the sweet potato slices can be used for butternut squash slices.
- If you don’t have Gruyère, you can use mozzarella or provolone cheese instead.
- Not a fan of kale? Try baby spinach instead! There’s no need to massage the spinach leaves before using.
- If you enjoyed this one, try my avocado grilled cheese, too!
How to Make Grilled Cheese in an Air Fryer
If you’d rather make your sandwich in an air fryer, follow my step by step instructions for air fryer grilled cheese. You can cook the sweet potato in the air fryer first, then add it to your sandwich and finish cooking your grilled cheese in the air fryer!
