Essential Ingredients
You only need a handful of heavy-hitting, highly accessible pantry staples to pull this magnificent, savory casserole together.
-
The Meat: 1.5 massive pounds of lean ground beef (80/20 works perfectly for deep, savory flavor).
-
The Vibrant Veggies: 3 massive bell peppers (use a mix of red, green, and yellow for a breathtakingly colorful dish!) and 1 large yellow onion, all sliced into thin strips.
-
The Seasoning: 1 standard packet (about 3 tablespoons) of your favorite fajita seasoning mix.
-
The Velvety Sauce: 1 massive can (10 oz) of diced tomatoes with green chiles (like Rotel) and 1/2 cup of full-fat sour cream or cream cheese to bind the filling together.

The Base: 8 massive flour tortillas, cut into bite-sized quarters or halves for easy layering!

The Cheese Blanket: 2 massive cups of freshly shredded Mexican blend or sharp cheddar cheese for that epic, breathtaking cheese pull!
Step-by-Step Instructions
-
Prep the Oven and Pan: Preheat your oven to a massive 375°F (190°C). Lightly grease a deep 9×13 baking dish perfectly with non-stick cooking spray.
-
Brown the Meat: In a massive, heavy-bottomed skillet over medium-high heat, vigorously cook the ground beef until it is completely browned. Highly Essential: Carefully drain off any excess grease!
-
Caramelize the Veggies: Add the thinly sliced bell peppers and yellow onion directly into the skillet with the beef. Vigorously sauté for exactly 5 to 7 minutes until the vegetables are breathtakingly tender and deeply fragrant.
-
Mix the Creamy Filling: Reduce the heat to low. Instantly add the fajita seasoning packet, the entire can of diced tomatoes with green chiles (do not drain!), and the sour cream. Vigorously stir everything together until it forms a breathtakingly smooth, velvety sauce that completely coats the meat and peppers.
-
Build the First Layer: Arrange exactly half of the quartered flour tortillas in a beautifully overlapping, even layer on the bottom of your prepared baking dish.
-
Add the Meat and Cheese: Spoon exactly half of the savory ground beef and pepper mixture directly over the tortillas. Sprinkle with 1 cup of the shredded Mexican cheese.
-
Repeat the Layers: Add the remaining tortillas in another beautiful layer. Top with the rest of the massive ground beef filling.
-
The Cheese Blanket & Bake: Generously smother the entire casserole with the remaining 1 cup of shredded cheese.

Frequently Asked Questions
Will the flour tortillas get soggy? This is a highly essential weeknight question! The tortillas will absolutely soften as they absorb the breathtakingly rich, savory juices of the beef and tomatoes, creating an authentic enchilada-like texture. If you want a firmer texture, you can use slightly stale corn tortillas instead!
Can I assemble this Fajita Casserole ahead of time? Yes! This is the ultimate meal-prep lifesaver. You can completely cook the beef and pepper filling and layer it with the tortillas in the pan. Cover it tightly and refrigerate for up to 3 days. Highly Essential: If baking from cold, add exactly 10 extra minutes to the baking time to ensure it is vigorously bubbling all the way through!
Can I use ground chicken or turkey instead of ground beef? Absolutely! This is a highly brilliant shortcut if you want a lighter meal. Lean ground turkey or even ground chicken works flawlessly with the bold fajita spices. Just be sure to season it vigorously!
