The inspiration behind this recipe:

We finally put our garden to rest a couple of weeks ago.  It’s hard to believe that at the end of November we could still reap produce but we didn’t have a hard frost until then.

I was doing a little refrigerator assessment this weekend and found a huge bag of our Poblanos.  They’d been in there a couple of weeks so it was time to do something with them.  It’s amazing how long something lasts that is homegrown and not shipped in from some far corner of the globe!

I roasted and peeled them all, froze about half and with the cold wind blowing outside, decided a good, spicy Mexican-inspired casserole with chicken was in order.

Yeah, baby!  This Mexican Chicken Poblano and Black Bean Tortilla Casserole!

Why roast Poblano peppers?

It’s a good idea to roast Poblano peppers before using them because the skin of mature Poblanos can be a bit leathery.  It also bumps up the flavor tremendously!

How to roast Poblano peppers:

  • Place them on a rimmed baking sheet.
  • Preheat the broiler to high, set a rack near the top–approximately eight inches away from the element works well.
  • Broil until the top is blackened, approximately 8-10 minutes.  Turn them over and blacken the other side–approximately 5-6 minutes.
  • Immediately cover with aluminum foil or another rimmed baking which will cause them to steam.  The steam is going to separate the skin from the flesh, making them easier to peel.
  • Peel and remove as many seeds as possible.  Resist the temptation to peel them under running water as you will rinse away flavor.
  • Poblano peppers freeze very well, so after roasting, just place them into a zipper top freezer bag and you’ll have roasted Poblano peppers ready to go!

How to make Mexican Chicken, Poblano and Black Bean Tortilla Casserole:

  • First, roast the peppers per the above directions and set them aside.
  • Next, you’ll need to fry the corn tortillas.  The reason you want to fry them up first is that they’re going to hold up better in a casserole.  Corn tortillas placed directly into a casserole tend to dissolve.  All they need is one to two minutes in hot oil and they’re good to go!  Simply drain on a cooling rack and they’re done!

  • Reserve some of the oil you fried the tortillas with and cook the onion, spices and tomato sauce.
  • Layer the ingredients just as you would lasagna and bake away.
  • Refrigerate and this casserole is the perfect make-ahead dish.  Assemble it up to one to two days ahead of when you’re going to need it.
  • This casserole also freezes great to bake whenever!

  1. Hi Carol,
    I did this with impossible meat, as I am a vegetarian and it was divine. My garden is booming with poblanos and this is definitely in the rotation. I added roasted corn and black olives. Thank you for the recipe!

  2. 5 stars
    I made this tonight and it was so good! I had never roasted poblanos before–that was a new experience for me. I served it with lime tortilla chips and salsa. Was a hit with my husband.

    1. Thanks so very much, Chris! So glad you and your hubby enjoyed! Roasting the peppers definitely takes the flavor to another level. Thanks again and hope you’ll keep in touch!

  3. I made this as written (ok, used a hoppy, fruity IPA) and it was amazing. Had a few Santitas handy to chase around the loose bits on the plate… nothing was left over.

    1. Hi, Dianne, Thanks so much for your question. I think they would. The thing I like about the Poblanos is that deep, smoky flavor they give the dish. Hope you enjoy and let me know how it goes.

  4. Carol, this looks so delish! I’ve made a couple casseroles like this before but have never fried the tortillas before. Great idea, and I’ll definitely do it next time 🙂

  5. That sounds delicious!

    And I don’t have a garden, but I still have peppers (and one lone tomato) from out last CSA pickup. (We didn’t have a frost until last week.) Local and really fresh – they do last so much longer!
