Making low carb Mexican casserole is surprisingly easy and doesn’t require fancy skills or hard-to-find ingredients. It’s a simple, fuss-free recipe that comes together in one skillet (or a small baking dish) with minimal cleanup. 

Let’s walk through the quick steps to bring it all together.

Step 1: Prep and Sauté

  • Preheat your oven to 350°F.
  • In a large pan, ideally an oven-safe skillet, warm some olive oil over medium heat. 
  • Once it’s hot, toss in chopped red bell pepper, chopped red onion, a bit of salt, and pepper. Sauté everything until the veggies start to soften and smell amazing.

Step 2: Season and Combine

  • Sprinkle in chili powder, cumin, and dried oregano. Let the spices cook for a minute or two so they can release their flavor.
  • Take the skillet off the heat and stir in sour cream, salsa, and shredded cooked chicken. Mix until everything’s coated and well combined. If your skillet isn’t oven-safe, go ahead and transfer the mixture to a small casserole dish.

Step 3: Finish and Bake

  • Drizzle some heavy cream over the top, then add a generous layer of shredded cheese.
  • Place the dish in the preheated oven and bake for 30 minutes, or until the remaining cheese is melted and slightly golden, and the casserole is heated through.
  • Top with fresh chopped cilantro right before serving and dig in!

Expert Tips for Perfecting Your Low Carb Mexican Casserole

Want to take your casserole game from good to mouthwatering? These little tweaks can make a big difference in flavor, texture, and ease. 

  • Use an Oven-Safe Skillet: If you’ve got a skillet that can go straight from stovetop to oven, use it! It saves you from washing extra dishes and helps everything cook evenly.
  • Toast the Spices: Don’t skip this part. Letting the chili powder, cumin, and oregano hit the heat brings out deeper, bolder flavors. It’s the secret to that warm, comforting kick.
  • Drain Extra Moisture from Veggies: Bell peppers and onions release a lot of water. Let them sauté until most of the moisture cooks off so your casserole doesn’t turn soupy.
  • Shred the Chicken Well: Go for small, even shreds of chicken. This helps every bite scoop up flavor and blend seamlessly with the creamy, cheesy goodness.
  • Don’t Overdo the Cheese: Tempting, we know. But a balanced amount of cheese gives you a gooey top without overpowering the dish. Just enough to melt and brown beautifully.
  • Use Taco Seasoning: For an extra burst of flavor, sprinkle some homemade taco seasoning into the mix. It adds a zesty, bold kick that perfectly complements the dish’s rich, cheesy base.
  • Garnish Right Before Serving: Add that fresh pop of chopped cilantro after baking. It keeps the flavor bright and adds a lovely contrast to the rich, cheesy base.

Even if you’re not a kitchen pro, these tips make the cooking process smoother and the end result even tastier. Small tricks, big payoff.
