Creamy Chicken Fajita Bake – Spicy, Melty & Weeknight Gold.

Today is Tuesday, December 23, 2025.¹ We are deep in the “holiday rush,” just two days away from Christmas. Between the gift-wrapping, the travel plans, and the anticipation of big holiday feasts, the last thing anyone wants to deal with on a Tuesday night is a sink full of dishes or a complicated stovetop technique.

The Creamy Chicken Fajita Bake is the ultimate “Weeknight Gold.” It takes the vibrant, smoky flavors of traditional sizzling fajitas—the charred peppers, the zesty lime, and the spiced chicken—and transforms them into a low-effort, high-reward casserole. By adding a creamy element (cream cheese and salsa), you create a sauce that binds the ingredients together, ensuring the chicken stays succulent while the cheese on top reaches that perfect, golden bubble. It’s a meal that feels indulgent but comes together with about ten minutes of hands-on work.

Ingredients

To get that authentic fajita flavor in a bake, the spice blend and the “crunch” of the vegetables are the most important variables.

The Protein & Veggies

1.5 lbs Chicken Breast: Cut into thin strips or bite-sized cubes.
3 Bell Peppers: Use a mix of red, yellow, and green for visual appeal. Sliced into strips.
1 Large Red Onion: Sliced into wedges.
2 tbsp Olive Oil.

The Creamy Fajita Sauce

4 oz Cream Cheese: Softened. This is the secret to the “velvet” texture.
1/2 cup Salsa: Choose “chunky” for extra texture and your preferred heat level.
1 tbsp Taco or Fajita Seasoning: (Or a mix of chili powder, cumin, garlic powder, and smoked paprika).
1 tbsp Lime Juice: To cut through the richness.

The Melty Topper

1.5 cups Shredded Mexican Blend Cheese: Or a mix of Monterey Jack and Sharp Cheddar.
Fresh Cilantro & Sliced Jalapeños: For garnish.

Instructions: The One-Dish Wonder

The goal is to let the oven do the heavy lifting. By baking everything together, the juices from the peppers and chicken create a natural “gravy” that mixes with the cream cheese.

1. The Prep

Preheat your oven to 400°F (205°C). Lightly grease a 9×13 inch baking dish.

2. Season the Base

Place your raw chicken strips, sliced peppers, and onions directly into the baking dish. Drizzle with olive oil and sprinkle the fajita seasoning over the top. Toss with your hands or tongs until everything is brightly coated in spices.

3. Add the Cream

In a small bowl, whisk together the softened cream cheese, salsa, and lime juice. Dollop this mixture over the chicken and vegetables. You don’t need to stir it in perfectly—it will melt and spread as it bakes.

4. The First Bake

Slide the dish into the oven and bake for 20 minutes. At this point, the chicken should be nearly cooked and the vegetables should be tender but not mushy.

5. The Cheese Finish

Remove the dish from the oven. Give everything a quick stir to ensure the melted cream cheese and salsa have coated the chicken.

Sprinkle the shredded cheese evenly over the top.
Bake for another 10–15 minutes, or until the cheese is bubbling and has a few golden-brown spots.

6. Garnish and Serve

Let the dish rest for 5 minutes (this allows the sauce to thicken). Top with fresh cilantro, a squeeze of extra lime, and jalapeños if you like it spicy.

Flavor & Texture Notes

This bake is defined by its “creamy heat.” The cream cheese mellows out the acidity of the salsa and the “bite” of the chili powder, resulting in a sauce that is rich and savory.

Texturally, the bell peppers provide a soft, sweet contrast to the lean, seasoned chicken. Because it’s a “bake,” the cheese on top provides a slightly chewy, salty crust that holds everything together. It is a comforting, warm dish that hits every corner of the palate—smoke, salt, cream, and tang.

FAQ

Can I use frozen peppers and onions?

Yes, but be careful! Frozen vegetables release a lot of water. If you use them, I recommend sautéing them for 5 minutes first to cook off the excess moisture, or your bake might turn out like a soup.

What should I serve this with?

This is incredibly versatile. It works beautifully inside warm flour tortillas, over a bed of cilantro-lime rice, or even tucked into a hollowed-out bell pepper for a “stuffed pepper” vibe.

How do I store and reheat leftovers?

Store in an airtight container for up to 3 days. When reheating, do so in the oven or on the stovetop if possible to maintain the texture of the chicken. If using a microwave, use a lower power setting so the cheese doesn’t become rubbery.
