Creating Your Delicious Fajita Casserole
This effortless black bean fajita casserole is designed for convenient weeknight meals, bringing together the vibrant flavors of fajitas. It features smoky bell peppers and onions, hearty black beans simmered in salsa and taco seasoning, and corn tortilla strips for added texture. Topped with Cotija cheese, avocado, sour cream, and fresh cilantro, it offers a complete and satisfying meal that is both comforting and nutritious. This dish can be easily customized with various beans or cooked meats and is also suitable for freezing.
Preparing this flavorful casserole begins with preheating your oven to 350°F. In a 12-inch cast-iron skillet, heat two tablespoons of olive oil over high heat until shimmering. Add sliced bell peppers and red onion, cooking them undisturbed for about six minutes until one side is charred. Stir in 1½ teaspoons of taco seasoning, continuing to cook for another two to three minutes until the vegetables soften and char further. Transfer the cooked vegetables to a plate. Reduce the heat to medium, add the thinly sliced garlic and the remaining tablespoon of olive oil to the skillet, stirring constantly for about 30 seconds until fragrant. Next, incorporate the rinsed black beans, one cup of refrigerated salsa, half a cup of water, the remaining half teaspoon of salt, and the last 1½ teaspoons of taco seasoning. Return the cooked vegetables and their juices, along with the corn tortilla strips, to the skillet, stirring to ensure everything is evenly coated. Remove the skillet from the heat and sprinkle two tablespoons of crumbled Cotija cheese over the mixture. Bake for approximately 12 minutes, or until the edges are bubbling and the cheese is beautifully melted. Finish by topping with sliced avocado, two tablespoons of sour cream, and two tablespoons of fresh cilantro. For an extra kick, pickled jalapeño slices or hot sauce can be added.
Expert Tips for Perfecting Your Casserole
Our Test Kitchen's insights ensure this black bean fajita casserole is not only delicious but also easy to prepare and versatile. For those seeking variety, feel free to swap black beans with pinto or kidney beans, as they work equally well. If you prefer a more succulent dish, simply incorporate an additional half cup of water. Using corn tortillas is highly recommended over flour tortillas, as they maintain their structure better and avoid becoming gummy. Alternatively, the casserole can be served in corn tortilla shells, in which case the tortilla strips can be omitted. Cotija cheese adds a distinct, tangy flavor, but Monterey Jack can be used for a milder, less pungent cheesy note.
Beyond the primary ingredients, bell peppers are a nutritional powerhouse, offering a low-calorie base rich in vitamin C and potassium, beneficial for heart health and sodium excretion. Black beans are crucial for this recipe, providing an excellent source of fiber for digestive well-being, plant-based protein, and non-heme iron. Refrigerated salsa acts as a convenient flavor enhancer, packed with vitamins and antioxidants from tomatoes, peppers, onions, and garlic. These nutritional aspects highlight the health benefits of this comforting dish. For cooking flexibility, while a cast-iron skillet is ideal for its heat retention and oven-safe properties, any ovenproof skillet or casserole dish can be used. If transferring to a separate dish for baking, ensure it's adequately sized. For future enjoyment, the casserole can be assembled and frozen in an airtight, freezer-safe container for up to three months. Thaw overnight in the refrigerator before baking, noting that baking time may be slightly extended. Leftovers can be stored in an airtight container in the refrigerator for up to four days and reheated in the microwave in one-minute intervals or in a 350°F oven until bubbling hot. This versatile casserole pairs wonderfully with Mexican red rice, cauliflower rice pilaf, or a refreshing jicama salad, offering a complete and satisfying meal for any occasion.
