Ingredients You’ll Need

Before we dive into the cooking process, here’s what you’ll need to create this protein-packed casserole:

• Vegetables – Bell peppers and onions are a must for authentic Mexican flavor. You can also add zucchini, mushrooms, or garlic to increase nutrients and flavor.
• Red enchilada sauce – This gives a smoky, tangy base for the casserole. Store-bought or homemade both work great.
• Green chilies – Mild diced green chilies add just the right hint of heat. For more spice, consider fire-roasted or hot chilies.
• Black beans – A plant-based protein source that also adds fiber, making this casserole even more filling.
• Chicken breast – Lean protein is key here. Use pre-cooked shredded chicken for convenience or cook fresh chicken to shred yourself.
• Corn tortillas – Cut into pieces and mixed in rather than rolled, they soak up the sauce while keeping the texture soft.
• Reduced-fat shredded Mexican cheese – Melts beautifully on top for a gooey finish. You can also try sharp cheddar or pepper jack.
• Low-fat cottage cheese – Adds creaminess without extra fat, and when blended, gives a smooth texture.
• Greek yogurt (2%) – A healthy alternative to sour cream, adding tanginess and extra protein to the dish.

How to Make High Protein Chicken Enchiladas

This recipe works on the stovetop or in a slow cooker, giving you flexibility depending on your schedule.

Stovetop Method

1. Cook the chicken: Heat a skillet over medium heat, lightly coat with oil or cooking spray, and cook the chicken breast for 4–5 minutes per side, until fully cooked (internal temp 165°F). Let it rest, then shred or dice.
2. Sauté the vegetables: In the same skillet, cook diced onions and bell peppers for 4–5 minutes, stirring occasionally until softened.
3. Combine everything: Add the shredded chicken back into the skillet along with green chilies, black beans, enchilada sauce, cottage cheese, and Greek yogurt. Stir to combine. Mix in cut-up corn tortillas until evenly coated.
4. Bake the casserole: Transfer the mixture to a lightly greased 9×13-inch baking dish. Sprinkle with shredded cheese and bake at 350°F for 15–20 minutes, until the cheese is melted and bubbly. Let it rest for 5 minutes before serving.

Slow Cooker Method

1. Prep ingredients: Dice onion and peppers, rinse black beans, and cut tortillas into bite-sized pieces.
2. Add chicken & vegetables: Place raw chicken in the slow cooker, then add onion, peppers, green chilies, black beans, and enchilada sauce. Stir to combine.
3. Slow cook: Cover and cook on low for 6–7 hours or high for 3–4 hours until chicken reaches 165°F and shreds easily.
4. Mix ingredients: Remove chicken, shred it, and return to the slow cooker. Add cottage cheese and Greek yogurt, stirring gently. Mix in the tortilla pieces until evenly distributed.
5. Bake for the final touch: Transfer the mixture to a greased baking dish, top with shredded cheese, and bake at 350°F for 15–20 minutes until melted and bubbly.

Ways to Customize

• Cheese: Full-fat, Monterey Jack, sharp cheddar, or even dairy-free alternatives work well.
• Protein options: Rotisserie chicken is a quick fix, ground turkey or beef adds more heft, and shredded pork adds a smoky twist.
• Tortilla variations: Flour tortillas for softness, or low-carb/high-protein options for more nutrition. Crushed tortilla chips on top add crunch.
• Veggies: Swap bell peppers with poblano or jalapeño for extra heat, or add mushrooms, zucchini, or spinach for more nutrients.
• Creaminess tweaks: Swap Greek yogurt and cottage cheese with sour cream and cream cheese if preferred.
• Sauce swaps: Green enchilada sauce for milder tang, or homemade sauce for full control over spices. Salsa verde works for a fresh twist.

FAQ

Do I need to blend the cottage cheese?
Blending gives a smoother texture, but you can leave it as-is if you don’t mind small curds.

Can I use flour tortillas?
Yes, though corn tortillas provide a more authentic enchilada flavor and slightly firmer texture.

How do I prevent soggy casserole?
Cut the tortillas into pieces and avoid adding extra sauce beyond the recipe amount.
