It makes a nice big casserole
This Mexican Casserole was a life-saver the other week. I didn’t have much time to make dinners or lunches, so I made this lovely big casserole, and we have several meals.
It was awesome to know that there was a healthy yummy meal ready in the fridge when I needed it! I could also see that this casserole would be great to take to a football party as a main dish!
The casserole was perfect, not too spicy, and not too bland. It’s a layered enchilada dish that’s simply loaded with veggies and yumminess. I served it with some Debi’s Flamin’ Hot Sauce (which I highly recommend!).
It was also delicious with a drizzle of homemade enchilada sauce. I make the enchilada sauce and keep a small container of it in the freezer; that way we always have fresh homemade sauce at the ready.
It’s your choice which milk you use. 2% milk will lower the calories of the recipe, while whole milk will give you a richer thicker casserole. You could also try plant-based milk; I’d recommend a neutral flavored one like unsweetened soy or almond milk.

Mexican Casserole Recipe
- 3 poblano chiles
- 2 large red bell peppers
- 2 cups frozen corn, thawed
- 1/3 cup all-purpose flour
- 1 teaspoon salt, divided use
- ¼ teaspoon freshly ground black pepper
- 2 cups 2% milk, or your choice
- 1 ½ cups vegetable broth
- 2 cups shredded Mexican blend cheese, divided use
- 1/3 cup finely chopped red onion
- 1/4 cup chopped fresh cilantro
- 2 large eggs, lightly beaten
- 1 15-ounce carton part-skim ricotta cheese
- 1 can 15.5 ounce white beans, drained and rinsed
- 18 6-inch white corn tortillas
- 1 cup thinly sliced green onions, divided use
- Preheat broiler to 450° F.
- Cut poblanos and bell pepper in half lengthwise; discard seeds and membranes. Place peppers, skin side up, on a foil-lined baking sheet; flatten with hand. Place corn on baking sheet. Broil 10 minutes or until poblanos and bell pepper are blackened and corn is lightly browned. Place poblanos and bell pepper in a zip-top plastic bag; seal. Let stand 10 minutes. Peel and coarsely chop; set poblanos and bell pepper aside separately.
- Place flour, ½ teaspoon salt, and black pepper in a large saucepan. Gradually add milk and broth, stirring with a whisk. Cook over medium heat until slightly thick (about 12 minutes), stirring constantly. Remove from heat. Combine milk mixture and poblanos in a blender; process until smooth. Stir pureed poblano mixture into remaining milk mixture.
- Preheat oven to 350° F.
- Combine bell pepper, corn, remaining ½ teaspoon salt, 1 cup cheese, red onion, cilantro, eggs, and ricotta.
- Coat bottom of a 13 x 9-inch baking dish with oil or cooking spray. Spread ½ cup sauce in bottom of dish. Arrange 6 tortillas over sauce, overlapping slightly. Spread half of ricotta mixture over tortillas; top with half of white beans. Sprinkle with 1/3 cup green onions and 2/3 cup cheese. Pour about 1 cup sauce over cheese. Repeat layers with 6 tortillas, remaining ricotta mixture, remaining beans, 1/3 cup green onions, 1 cup sauce, and 6 tortillas. Pour remaining sauce over tortillas. Coat 1 side of foil with oil or cooking spray. Place foil, coated side down, over casserole. Bake at 350° F for 30 minutes or until bubbly.
- Uncover; sprinkle with remaining cheese. Bake, uncovered, 15 minutes or until cheese melts. Let stand 15 minutes. Garnish with remaining green onions, sliced avocado, and hot sauce as desired. Enjoy!
