Step by Step Directions

poblano chicken casserole recipe

Making this Mexican Poblano Chicken Casserole is straightforward and requires just a few simple steps to create a bubbling, golden masterpiece.

  • Preheat your oven to 350°F and grease a casserole dish.
  • Heat olive oil in a large skillet and sauté the diced onion, minced garlic, and diced poblano peppers until they become soft and fragrant.
  • Transfer the sautéed vegetables to a food processor or blender, then add the half-and-half, sour cream, salt, pepper, and cumin, blending until smooth.
  • In a large bowl, combine the canned chicken with the blended pepper mixture and 1 cup of the Colby-Monterey Jack cheese, mixing thoroughly.
  • Pour the chicken mixture into your prepared casserole dish and spread evenly.
  • Sprinkle the remaining 1 cup of cheese over the top of the casserole.
  • Cover the dish with foil and bake for 35 minutes.
  • Remove the foil and continue baking for an additional 10-15 minutes until the top is golden brown and bubbly.
  • Let the casserole rest for 5 minutes before serving to allow it to set properly.

For the best flavor depth, consider using a premium Indian spice grinder to freshly grind your cumin and other spices before adding them to the creamy pepper mixture.

Substitutions and Variations

  • Add some crunch – Mix in a cup of frozen corn or diced bell peppers for extra texture and color, which also helps stretch the dish if you’re feeding a crowd
  • Rice or pasta version – Stir in 2 cups of cooked rice or small pasta like orzo to make it heartier, turning this from a simple casserole into a full meal deal
  • Vegetarian twist – Skip the chicken entirely and double up on black beans or pinto beans, adding extra cumin and maybe some smoked paprika to keep the flavor interesting

Additional Things to Serve With This Dish

This casserole is basically a warm hug on a plate, but to be frank, even warm hugs need some friends to make the meal complete.

  • Mexican rice – Because what’s a poblano casserole without its trusty sidekick, and you can totally use the boxed stuff if you’re not feeling fancy.
  • Simple black beans – Just drain, rinse, and warm them up with a pinch of cumin, or go wild and add some diced onion if you’re feeling ambitious.
  • Fresh corn tortillas – Warm them up and use them to scoop up every last creamy bit, because forks are overrated sometimes.
  • Crisp romaine salad – Toss with lime juice, olive oil, and a sprinkle of cotija cheese to cut through all that rich, melty goodness.
  • Cilantro lime rice – Cook regular white rice but stir in chopped cilantro and lime juice at the end, which makes you feel like you actually tried.
  • Warm flour tortillas – Perfect for making little casserole tacos, and honestly, is there anything flour tortillas can’t improve?
  • Simple guacamole – Even the store-bought kind works great, though mashing a few avocados with lime and salt takes like three minutes.

Cooking Tips & Tricks (Chef’s Notes)

Let me share some game-changing tricks that’ll turn you into a poblano casserole wizard, or at least someone who doesn’t accidentally create a watery mess.

  • Roast those poblanos first – Char them over an open flame or under the broiler until the skin blisters and blackens, then steam them in a paper bag for 10 minutes before peeling, because this adds a smoky depth that’ll make people think you actually know what you’re doing.
  • Drain your chicken like your life depends on it – Canned chicken holds onto liquid like a sponge, so press it between paper towels or even give it a gentle squeeze to avoid turning your creamy casserole into poblano soup.
  • Let the sautéed veggies cool off – Throwing hot onions and peppers directly into that sour cream mixture will curdle it faster than you can say “oops,” so give them a few minutes to cool down.
  • Shred your own cheese – Pre-shredded cheese has anti-caking agents that prevent proper melting, which means you’ll get grainy instead of gloriously gooey, and nobody wants sad cheese.
  • Don’t skip the resting time – Let this beauty sit for 10 minutes after baking so everything can settle and thicken up, even though waiting feels like torture when it smells that good.
  • Cover tightly with foil – Create a proper seal around the edges of your dish so the steam stays trapped and keeps everything moist during that first 35 minutes of baking.

Fun “Did You Know?”

Beyond its impressive nutritional profile, this Mexican poblano chicken casserole connects you to centuries of culinary tradition and surprising food facts.

Did you know poblano peppers originated in Puebla, Mexico, around 1,000 years ago? They’re actually quite mild, ranking only 1,000-2,000 on the Scoville scale. When dried, poblanos become ancho peppers, completely transforming their flavor profile.

Colby-Monterey Jack cheese combines two American innovations from the 1880s. The half-and-half in your casserole contains exactly what its name suggests—equal parts milk and cream.

I love how this dish blends ancient Mexican ingredients with modern American dairy innovations.
