Why you’ll love this simple after-work dinner!

Growing up in the south, we ate at Mexican restaurants on a WEEKLY basis which meant we always had leftover fajita veggies in the fridge. My mom would use those leftovers to make us quesadillas for dinner the next night and it was always one of my GO-TO meals that she would make.

These meatless quesadillas are my take on those simple and savory quesadillas I grew up eating – I hope you love them!

Ingredients needed

The simple ingredients for these flavorful vegetarian quesadillas are listed fully down in the recipe card but let’s briefly go over the pantry staples needed including a few substitutions you can make as desired!

Black or pinto beans – Adds protein and makes the quesadillas hearty and filling. Either option works great. I’ve even made this with refried beans!
White onion – Caramelizes as it cooks and adds sweetness and depth.
Bell peppers – Adds sweetness and color. I used a red bell pepper + a green one but any color combo of bell peppers will work great!
Poblano pepper – Adds a mild smoky flavor and subtle heat. A jalapeño can be substituted for more spice!
Butter – Helps the onions caramelize and adds richness.
Flour tortillas – Large tortillas work dependable for folding. Whole wheat tortillas can also be used or gluten-free tortillas as needed.
Mexican cheese blend – Melts beautifully and adds familiar quesadilla flavor. Monterey Jack, cheddar, or pepper jack also work well.
Other options – this method is quite customizable so add your go-to veggies and have fun with it! I think this would be great with potatoes, sweet potatoes, leafy greens, tomato, etc. So many options!

Recipe Tips

Cook the onions slowly. Letting them soften and caramelize adds huge flavor to the filling.
Don’t overfill the quesadillas. Too much filling makes them harder to flip and can cause them to fall apart.
Cook on medium-low heat. This ensures the tortilla gets crispy while the cheese fully melts.
Use cheese on both sides of the filling. This helps hold everything together once melted.
Let them rest for a minute after cooking. This helps the cheese set so the filling stays inside when slicing.
