Directions: Chicken Enchilada Casserole With Cauliflower

Step 1: Prepare the Cauliflower
Begin by steaming the cauliflower florets until tender, about 8-10 minutes. You want them soft enough to mash but not mushy.
Step 2: Sauté the Aromatics
In a large skillet, heat the extra-virgin olive oil over medium heat. Add the chopped onion and minced garlic, cooking until the onion is translucent and fragrant, about 5 minutes.
Step 3: Mix the Ingredients
In a mixing bowl, combine the steamed cauliflower, sautéed onion and garlic, shredded chicken, taco seasoning, diced green chilis, red enchilada sauce, large egg, egg white, salt, and black pepper. Mix well until everything is evenly coated.
Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C). Grease your baking dish with a little olive oil. Spread the cauliflower mixture evenly in the dish, then sprinkle the reduced-fat Mexican cheese blend on top.
Step 5: Bake the Casserole
Bake in the preheated oven for about 25-30 minutes or until the cheese is melted and bubbly, and the edges are slightly golden.
Step 6: Garnish and Serve
Remove the casserole from the oven and let it cool for a few minutes. Top with fresh cilantro, diced tomatoes, and sliced avocado before serving.
Dairy-Free/Gluten-Free Swaps

- For a dairy-free version, substitute the reduced-fat Mexican cheese blend with a dairy-free cheese alternative.
- Ensure the enchilada sauce is gluten-free, or make your own using gluten-free ingredients.
- Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) for a vegan option.
- Use quinoa or brown rice instead of cauliflower for a different base, if desired.
Problems & Prevention
To prevent any mishaps while making your Chicken Enchilada Casserole With Cauliflower, keep these tips in mind:
- Don’t overcook the cauliflower; it should be tender but not mushy, as it needs to hold its shape in the casserole.
- Ensure all ingredients are well mixed to avoid dry spots in the casserole.
- Let the casserole cool for a few minutes after baking; this will help it set and make serving easier.
- If you find the casserole is too dry, a splash more enchilada sauce can help moisten it before serving.
