Why you’ll love this simple weeknight 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 FAVORITE meals that she would make.
These meatless quesadillas are my take on those simple and delicious quesadillas I grew up eating – I hope you love them!

Ingredients needed
The simple ingredients for these tasty 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 best for folding. Whole wheat tortillas can also be used or gluten-free tortillas as needed.
- Mexican cheese blend – Melts beautifully and adds classic quesadilla flavor. Monterey Jack, cheddar, or pepper jack also work well.
- Other options – this recipe is very customizable so add your favorite veggies and have fun with it! I think this would be great with potatoes, sweet potatoes, leafy greens, tomato, etc. So many options!
How to Make Loaded Veggie Quesadillas
Just a reminder that you can find the FULL written vegetarian quesadilla recipe down in the recipe card, but I want to quickly go over how to make them with visuals for you :)
- In a large skillet over medium-high heat, saute the onions until they begin to brown and caramelize. Add in the bell peppers + poblano pepper and season with spices and salt.
- Place your drained and rinsed beans into a bowl and season with salt, paprika, onion powder, and garlic powder. Add the bean mixture to the skillet with the veggie mixture and mix to combine.
- Assemble the fajitas by placing your tortilla on a clean surface. on one half of the tortilla, top with cheese then the vegetable filling. Add more cheese and fold over to seal.
- Grease the same skillet with butter and gently place the folded quesadilla into the pan. Cook for 2-4 minutes per side or until it’s a nice golden brown on both side. Top with sour cream and pico de gayo and enjoy!
Vegetarian Quesadilla Ideas
Once you have the base recipe down, it’s easy to customize these meatless quesadillas with different fillings.
Here are some ideas for things to add:
- Corn or roasted sweet corn
- Sautéed mushrooms
- Spinach or kale
- Cooked sweet potatoes
- Avocado slices after cooking
- Jalapeños for extra heat
- Different cheeses like pepper jack or queso Oaxaca
You can also swap the beans for refried beans, black beans, or even lentils for different textures and flavors!! Let me know what you end up trying!
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.

Easy Vegetarian Quesadilla Recipe
Ingredients
- 1 white onion, thinly sliced
- 1 red bell pepper, deseeded and diced
- 1 green bell pepper, deseeded and diced
- 1 poblano pepper, deseeded and minced
- 1 tablespoon butter
- 1 tablespoon canola oil
- 1 teaspoon fine sea salt
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- ½ teaspoon onion powder
- 8 flour tortillas, recipe makes 7-8 tortillas depending how much you put in each one
- 4 cups mexican style shredded cheese blend
For the Beans
- 15 oz can of black or pinto beans, drained and rinsed
- ½ teaspoon fine sea salt
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika
- ½ teaspoon onion powder
Instructions
- In a large skillet over medium heat, saute the onions with butter and oil for 10-15 minutes. Add bell peppers and poblano pepper into the skillet with the onions. Season with fine sea salt, garlic powder, smoked paprika, onion powder. Saute on med-low for 10-15 minutes, add ¼ cup water as needed to deglaze the pan.
- Place drained and rinsed beans into a large bowl, season with all spices and toss together.
- Once your veggies are cooked to your desired doneness, remove from heat right as any remaining water has cooked off, and place into a bowl with your beans. Mix together.
- On your work surface, place a tortilla, then ¼ cup cheese on slightly less than one half of the tortilla (because the fold has to go over the height of the toppings), then evenly spread about 3 heaping spoonfuls of your bean/veggie mixture, then top with ¼ cup cheese before folding tortilla over.
- Wipe out skillet and place it on low heat. If desired, take a bit of butter and spread it in the pan before placing quesadilla. Cook for 2-4 minutes per side to get a nice browning and melt the cheese, use a spatula to check the underside for doneness.
- Remove from the pan and place on a wire rack to cool for meal prep or directly onto plates for serving. Repeat with remaining quesadillas.
