👩🏻‍🍳 Why You'll Love This Recipe

This vegetarian Mexican recipe is kind of like a lasagna, but with a Mexican spin. Tortillas play the part of the lasagna noodles, salsa and a southwest corn blend provide great flavor and chunks of veggies.

Fiesta style shredded cheese melts into a gooey, cheese-y, deliciousness that holds the whole thing together. The result is a flavorful, fun dish that is easy and healthy, too. (Shhhh…don’t tell the kids, but I snuck some fresh spinach in there as well, to give it a little extra nutritional boost!!)

Served with a Chipotle Lime Slaw, a handful of corn chips, and this delicious sour cream guacamole - just like that, dinner is ready! Or prepare this delicious recipe for vegan black beans to serve on the side for a hearty and nutritious complete meal.

I am always excited to make a dish where I can do all the work up front (not too much work, though!) and then forget about it while it cooks. The crock pot is perfect for that, as are casseroles and other baked dishes.

This recipe is great because you put it together, throw it in the oven, and then go about your business until it is ready. While you are waiting, you can do the laundry, empty the dishwasher, help the kids with their homework, etc. OR, here’s a better idea...sit down, put your feet up, and relax for a bit! Maybe even have a little glass of wine! Either way, you will still have a great meal ready for the whole family in 25 to 30 minutes. 🙂

🥘 Ingredients Needed

Here are the ingredients I used for this recipe. I like keeping my meals low calorie and low fat BUT I know times are trying right now - so please feel free to substitute with the items you have in your pantry and refrigerator.

• whole wheat tortillas (you can substitute regular flour tortillas)
• fat free refried beans
• chunky salsa
• Seasoned Southwestern Corn (you'll find this in the frozen section)
• fresh baby spinach
• reduced fat fiesta blend shredded cheese (or any mild cheese)
• green onions

🔪 Instructions

1. Preheat the oven and prepare the pan by spraying with non-stick cooking spray. Place a tortilla in the bottom of the pan, spread refried beans on the tortilla, and then top with salsa.
2. Distribute corn evenly on top.
3. Top with a handful of the spinach and then cheese.
4. Place the second tortilla on top.
5. Repeat layering of the beans, salsa, corn, spinach, and cheese.
6. Place the third tortilla in the pan. Top with remaining salsa and cheese. Sprinkle with green onion.
7. Bake until hot and bubbly.

💭 Top Tips

What sauce is best?

I use salsa. It's a staple pantry ingredient that I always have on-hand. It's fat free and low cal - a total win/win! If you don't have salsa, consider substituting with red or green enchilada sauce. Salsa verde would also be a great swap!

What cheese is best?

The prepackaged/shredded fiesta blend is my first choice because there are already spices added to the cheese. Less work for you - yay! But if you need to substitute that, almost any shredded cheese would be terrific - pepper jack, cheddar or Queso Fresco would be great choices.

Queso Fresco is a Mexican farmers type cheese. It's super melty and very delicious!

How spicy is it?

That really depends on the salsa you use. There's no additional spices, I used a mild salsa and it wasn't spicy in the least, just flavorful.

One of the secrets to this dish is to use Bird's Eye Seasoned Southwestern corn (in the freezer section). It has some additional seasoning, and red and green peppers and onion. But, if you don't have it on hand, you can always use regular frozen corn and you should be fine.

📖 Variations for this vegetarian Mexican recipe

What else can I add to the casserole?

If you want to veg it up, sautéed onions and peppers would be a great addition, and sliced black olives add a pop of salty goodness!

A sprinkle of minced cilantro adds a bright pop of green when it comes out of the oven.

Substitute ingredients

Also, you can adjust the amounts or substitute ingredients in the recipe as you wish. Love refried beans? Increase the amount on each layer. Watching your sodium? Substitute low sodium salsa. It is a very forgiving recipe, which gives you tons of options!

Make your own tortillas

You can complete the meal with some homemade flour tortillas. Don't stress, they are super easy to make, yummy too!

Adding meat

We have been trying to minimize our consumption of meat lately, so I specifically set out to create a vegetarian Mexican recipe. But that doesn't mean that you can't enhance this with some cubed cooked chicken, or some browned ground beef! Experiment based on what your family likes best.

Like lasagna, only better!

This vegetarian Mexican recipe is cheesy, filling and delicious but not a heavy meal. The salsa and vegetables keep it fresh and light.

What the picture does not illustrate is that my family was behind me in the house, hungrily waiting for me to decide that I had enough pictures so that we could actually have dinner! Thanks, guys, for being so patient!!

Mexican Mac 'n Cheese is truly the stuff dreams are made of (my dreams anyways!) rich, cheesy and satisfying. Or my Enchilada Bake, made in the crock pot (love that!) is another great meal. If you're a meal planner, this one is perfect because it's freezer friendly!
