1½ cups (1 red, 1 green)

Fresh or frozen

Onion, sliced

1 medium

Yellow or white

Taco seasoning

Store-bought or homemade

Cheddar or Mexican blend cheese

🥣 Step-by-Step: How to Make Fajita Chicken Casserole

Step 1: Preheat & Prep

Preheat oven to 375°F (190°C)

Grease a 9x13-inch baking dish — or line with parchment

Step 2: Mix the Base

In a large bowl, combine:

Shredded chicken

Instant rice

Cream of chicken soup

Sour cream

Taco seasoning

1 cup cheese

Chicken broth

Stir until well blended

✅ No lumps? You’re doing it right.


Step 3: Add Veggies

Fold in:

Sliced bell peppers

Onion

Optional: Diced tomatoes with chilies

Mix gently — don’t crush the rice

✅ Frozen veggies? No need to thaw — just toss in.


Step 4: Bake to Golden Perfection

Pour mixture into the prepared dish

Spread evenly

Top with remaining 1 cup cheese

Bake 25–30 minutes, until:

Rice is tender

Cheese is bubbly and golden

Center is hot

✅ Cover with foil if top browns too fast.


Step 5: Rest & Serve

Let cool 5–10 minutes — helps it set

Scoop and serve — each bite should be creamy, cheesy, and packed with fajita flavor

Pair with:

Guacamole

Salsa

Sour cream

Or just a fork — it’s that good

Leftovers? Reheat in the oven or air fryer — never microwave (kills the texture).

Assemble, refrigerate, bake when ready (add 5–10 mins)
