How to Make Keto Chicken Fajita Casserole
Ready to get cooking? Follow these simple steps for a delicious keto dinner.
Step 1: Preheat and Prep. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with some of your oil.
Step 2: Sauté Aromatics. Heat 1 tablespoon of olive oil in a large skillet over medium high heat. Add the sliced onion and bell peppers. Cook, stirring occasionally, until they start to soften, about 5 7 minutes. Add the minced garlic and cook for another minute until fragrant. Remove the vegetables from the skillet and spread them evenly in the prepared baking dish.
Step 3: Cook the Chicken. In the same skillet, add the remaining 1 tablespoon of olive oil. Add the bite sized chicken pieces. Sprinkle them generously with the fajita seasoning. Cook the chicken, stirring frequently, until it’s browned and cooked through, about 7 10 minutes. Make sure there’s no pink left.
Step 4: Combine and Season. Add the cooked chicken to the baking dish with the vegetables. In a small bowl, whisk together the salsa and sour cream. Pour this mixture evenly over the chicken and vegetables in the baking dish. Gently toss to coat everything.
Step 5: Add Cheese and Bake. Sprinkle the shredded cheese evenly over the top of the casserole. Place the baking dish in the preheated oven. Bake for 15 20 minutes, or until the cheese is melted, bubbly, and slightly golden brown.
Step 6: Rest and Serve. Let the casserole rest for a few minutes before serving. This allows the flavors to meld and makes it easier to serve. Garnish with your favorite toppings like sliced avocado, fresh cilantro, or jalapeños if you like it spicy.
Do’s and Don’ts for Keto Fajita Casserole Success
Here are some tips to ensure your casserole turns out perfectly every time.
| Do’s | Don’ts |
| Do use pre cut vegetables if you’re short on time. | Don’t use store bought fajita seasoning mixes that contain added sugars or starches. Always check the label. |
| Do taste your fajita seasoning to ensure it’s low carb and to your liking. | Don’t use high carb salsas. Opt for brands specifically labeled low sugar or keto friendly. |
| Do consider adding a pinch of cayenne pepper or a diced jalapeño for extra heat. | Don’t overcook the vegetables in the initial sauté; they will continue to cook in the oven. |
| Do use chicken thighs for a richer, more moist casserole. | Don’t skip the resting time. It helps the casserole set up properly. |
| Do serve with a side salad or some avocado for extra healthy fats. | Don’t add any rice or beans, as these are high in carbs and not keto friendly. |
