Potato & Cheddar Quesadilla

"Here's my favorite way to use up left-over mashed potatoes. If your mashed potatoes are flavored with garlic, onions, etc. it's all the better. Measurements are approximate since I usually throw this together to use up leftovers in the fridge. If my potatoes are plain, I have been known to add a little chicken bouillon to give them more flavor. Serving size may vary- my two year-old DD and I share one of these for lunch. This definitely is not a "diet" meal, but, it's delicious!"

    This recipe was great. It was even better than I guessed it would be. I had used a small pack of instant loaded potatoes. I also used onion flakes and omitted the red pepper. Otherwise, I followed the instructions exactly. The quesadillas were very flavorful. My son loved them. He put buffalo sauce on his for a kick.

    I've been making this recipe for ages and I guess I never rated it. This is perfect for using leftover mashed potatoes and there isn't much that's more comforting than potatoes and cheese.

    WOW! When I looked for recipes to use up a ton of leftover mashed potatoes, I didn't see this one coming. I'm so glad you are this creative and generous to share! Made mine with Cotija cheese ("mexican parmesan", crumbly like feta)and some precooked fajita-seasoned chicken. The potatoes already had green onion and garlic so I skipped that and sprinkled everything with a dusting of spanish paprika for smoky good measure! Perfect 5 for ease of preparation, originality and great taste. What is that, 15 stars???

    Good comfort food, Amy. I didn't want to clean a pan so I just baked in the oven (didn't even use oil) so I thought it was pretty healthy! They are so go piping hot and room temp. Thanks for posting. Roxygirl

    This is so random and I would never have thought of it. Made for a quick lunch using leftover mashed potatoes from Thanksgiving. I'd make this again to use up leftovers for lunch but I wouldn't go out of my way to make potatoes for this. Great idea and tasted great too. Thanks for sharing.


I love to cook and experiment with foods- and I rarely follow a recipe exactly.
