This delicious Enchilada Casserole makes an ordinary weeknight dinner into an extraordinary Mexican dinner. Try it!
Preheat oven to 450 F degrees.
Mix Green Enchilada simmer sauces and whipping cream in a large bowl. Season to taste with salt.
Heat 3 tbsp of oil in a large saucepan over medium-high heat. Add the onion and sauté until tender, about 3 minutes. Add the poblano peppers and cook for another 3 minutes. Add frozen corn, mix thoroughly, turn the heat off, season with salt to taste and set aside.
In a medium saucepan, add the remaining oil and heat over medium-high heat. When oil is hot, dip one tortilla at a time for 10 seconds, turn and fry for an extra 10 seconds. Remove and place over paper towels. Repeat for the remaining tortillas. NOTE: THIS STEP IS IMPORTANT IF YOU WANT YOUR TORTILLAS TO HOLD THE FILLING AND SAUCE. OTHERWISE, THEY WILL GET SOGGY AND MUSHY.
Overlap 6 fried tortillas - or as many as you need to cover the whole surface - in a rectangular or oval baking dish. Top tortillas with the zucchini & squash shreds. Season with salt and pepper. Pour 1/3 of the Green Enchilada sauce mixture evenly over the zucchini/squash mix.
Cover with another layer of tortillas and add the poblano & corn mixture. Pour another 1/3 of the Green Enchilada sauce over the poblano/corn mixture.
Top with the remaining tortillas. Pour the last 1/3 of the Green Enchilada sauce evenly over the tortillas. Sprinkle mozzarella cheese. Cover with foil making sure foil is not touching cheese.
Place in the oven and bake until bubbling, about 40 minutes. Serve the enchilada casserole with a side of refried beans. Provecho!
