Ingredients Method

Ingredients

  

• 2 cups cooked shredded chicken (rotisserie breast or poached chicken works great)
• 1 cup salsa (choose a low-sodium, chunky salsa you like)
• 1/2 cup low-sodium chicken broth
• 1 tablespoon olive oil (or avocado oil)
• 1 medium yellow onion, diced
• 1 red bell pepper, diced
• 1 cup corn kernels (fresh, canned, or frozen)
• 1 cup black beans, rinsed and drained
• 1 teaspoon ground cumin
• 1 teaspoon chili powder
• 1/2 teaspoon smoked paprika (optional, but adds depth)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 teaspoon salt (adjust to taste)
• 1/4 teaspoon black pepper
• 6 small corn tortillas, cut into strips or wedges
• 3/4 cup reduced-fat shredded Mexican blend cheese (or part-skim mozzarella with a sprinkle of cheddar)
• 1/2 cup plain nonfat Greek yogurt (for topping, optional)
• Fresh cilantro, chopped (optional)
• Lime wedges (optional, for serving)

Method

 

1. Preheat and prep: Heat the oven to 375°F (190°C). Lightly mist a 9x13-inch baking dish with cooking spray.
2. Sauté the veggies: Warm the olive oil in a large skillet over medium heat. Add onion and bell pepper. Cook 4–5 minutes, until softened. Stir in corn and cook 1 more minute.
3. Add spices: Sprinkle in cumin, chili powder, smoked paprika, garlic powder, onion powder, salt, and pepper. Stir for 30 seconds to bloom the spices.
4. Make the sauce base: Pour in salsa and chicken broth. Stir and bring to a gentle simmer for 2–3 minutes. You want a saucy, slightly thickened mixture.
5. Stir in chicken and beans: Add shredded chicken and black beans to the skillet. Toss to coat everything evenly. Turn off the heat.
6. Layer it up: Scatter half the tortilla strips in the baking dish. Spoon half the chicken mixture over the tortillas. Add a light sprinkle of cheese. Repeat with remaining tortillas, remaining chicken mixture, and finish with the rest of the cheese.
7. Bake: Cover loosely with foil and bake for 15 minutes. Remove foil and bake another 8–10 minutes, until the cheese is melted and the edges bubble.
8. Rest and garnish: Let the casserole rest 5–10 minutes so it sets. Top with dollops of Greek yogurt, chopped cilantro, and a squeeze of lime, if using.
9. Serve: Cut into squares and serve warm. Add extra salsa or hot sauce on the side if you like more heat.

What Makes This Special

This casserole keeps all the taco fun while trimming calories in smart, satisfying ways. We use lean shredded chicken, plenty of fiber-rich veggies, and a light hand with cheese.

Corn tortillas add that taco vibe without overdoing carbs. Everything bakes together so the flavors meld into warm, saucy layers, and you still get a gentle crunch on top. It’s comfort food that doesn’t weigh you down.

• Light yet filling: Lean protein and fiber keep you full without a heavy sauce.

• Great for leftovers: Reheats beautifully for lunches and quick dinners.

Keeping It Fresh

Let leftovers cool completely, then cover tightly or portion into airtight containers.

Refrigerate for up to 4 days. Reheat covered in the microwave in 60–90 second bursts until hot, or warm in a 325°F oven for 12–15 minutes.

To freeze, wrap cooled portions well and freeze up to 2 months. Thaw overnight in the fridge, then reheat as above.

If the casserole seems a little dry after freezing, splash in a tablespoon of broth or add a spoonful of salsa before reheating.

Why This is Good for You

• Lean protein: Shredded chicken helps keep you full and supports muscle health with fewer calories than higher-fat meats.
• Fiber power: Black beans and veggies add fiber, which supports digestion and steady energy.
• Smart carbs: Corn tortillas deliver that taco feel without heavy layers of dough. They’re naturally portion-friendly.
• Lighter dairy: Reduced-fat cheese and Greek yogurt bring creaminess and calcium without overloading calories.
• Sodium control: Using low-sodium broth and rinsed beans helps keep salt in check.

Pitfalls to Watch Out For

• Too much liquid: Watery salsa or extra broth can make the casserole soupy. Use a thick salsa and measure liquids.
• Over-cheesing: Cheese adds up fast.

  Measure your cheese so the calories stay in line.

• Salt creep: Preseasoned chicken or salty salsa can push sodium high. Taste before adding extra salt.
• Overbaking: Too long in the oven can dry out the chicken. Bake just until the cheese melts and it bubbles.

Alternatives

• Protein swaps: Use ground turkey (93% lean) browned with the spices, or shredded rotisserie chicken breast.

  For vegetarian, try crumbled extra-firm tofu or more beans.

• Tortilla tweaks: Swap corn tortillas for whole-wheat tortillas or even thinly sliced zucchini for an extra-light, low-carb option.
• Dairy-free: Use a plant-based shredded cheese that melts well and top with dairy-free yogurt or guacamole.
• Veggie boost: Add diced zucchini, mushrooms, or spinach to the sauté step for more volume and fiber.
• Spice levels: For mild, use a gentle salsa and skip chili powder. For heat-lovers, add chipotle in adobo or a pinch of cayenne.

FAQ

Can I use pre-cooked rotisserie chicken?

Yes. Remove the skin and shred the breast meat for a leaner option.

It saves time and still tastes great once it’s mixed with the salsa and spices.

What can I use instead of black beans?

Pinto beans or white beans work just as well. If you’re avoiding legumes, sub in extra veggies like chopped zucchini, cauliflower rice, or more bell pepper.

How do I make it gluten-free?

Use certified gluten-free corn tortillas and check labels on salsa, broth, and spices. Most basic versions are naturally gluten-free, but it’s good to verify.

Can I assemble it ahead?

Yes.

Assemble up to 24 hours in advance, cover, and refrigerate. Add 5–10 extra minutes to the bake time since it will be cold going into the oven.

How many calories per serving?

It depends on your exact ingredients, but with lean chicken, reduced-fat cheese, and low-sodium options, you’re typically in the range of 280–350 calories per serving for eight portions. Use a nutrition calculator with your brands for precision.

Will corn tortillas stay firm?

They soften as they absorb the sauce, creating a layered, enchilada-like texture.

If you want more structure, lightly toast the tortilla strips in a dry skillet first.

Can I use fresh tomatoes instead of salsa?

You can. Dice tomatoes and simmer them with a little onion, garlic, lime, and spices until thick. Just make sure the mixture reduces so the casserole isn’t watery.

What cheese melts best here?

A reduced-fat Mexican blend melts nicely and keeps calories lower.

Part-skim mozzarella with a small handful of sharp cheddar also gives good pull and flavor.

How do I add more greens?

Stir a few handfuls of baby spinach into the hot chicken mixture until wilted before layering. You can also serve the casserole over a bed of shredded lettuce.

Can I make it spicier without extra calories?

Yes. Add jalapeño slices, crushed red pepper, or a splash of hot sauce to the sauce mixture.

Spices bring the heat without adding significant calories.
