🥣 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).
