Step‑by‑Step Instructions for Cheesy Chicken Cauliflower Rice Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it heats, take a moment to grease a 9×13-inch casserole dish with avocado oil to prevent sticking. This ensures your Cheesy Chicken Cauliflower Rice Casserole comes out easily once baked, allowing for perfect serving straight from the pan.
Step 2: Sauté the Onions
In a Dutch oven or large pot over medium-high heat, add about 1 tablespoon of avocado oil. Once the oil is hot, toss in the diced onions and sauté for 3-4 minutes until they turn soft and translucent. This step builds the foundational flavor for your casserole, making it aromatic and inviting.
Step 3: Cook the Cauliflower Rice
Add riced cauliflower to the softened onions in the pot, seasoning with kosher salt and ground black pepper. Cook for 10-12 minutes, stirring occasionally, until the cauliflower is golden and soft. It’s essential to allow moisture to evaporate, establishing a firm base for the casserole as it combines with other ingredients.
Step 4: Add Garlic
Stir in the minced garlic and cook for an additional minute until fragrant. The garlic should become aromatic, enhancing the overall flavor of your Cheesy Chicken Cauliflower Rice Casserole. Ensure you keep stirring to prevent the garlic from burning as it infuses the mixture with rich fragrance.
Step 5: Create the Creamy Mixture
Lower the heat and pour in the low-fat milk, followed by garlic powder, Italian seasoning, Dijon mustard, cream cheese, and plain Greek yogurt. Stir thoroughly until the cream cheese melts and all ingredients are well blended. The spinach should be added in at this stage, wilting as it mixes in, creating a luscious, creamy consistency.
Step 6: Combine Protein and Rice
Fold in the cooked and shredded chicken along with the cooked white jasmine rice, ensuring everything is evenly mixed. Take care that each scoop of your Cheesy Chicken Cauliflower Rice Casserole holds the delightful combination of veggies, chicken, and rice, providing balanced nourishment in every bite.
Step 7: Transfer to Casserole Dish
Carefully transfer the mixture into the prepared casserole dish, spreading it evenly throughout the pan for even cooking. This layer is crucial for creating that delicious cheesy topping later on. Prepare for the finale of this homestyle dish by ensuring it’s well compacted but not squished.
Step 8: Top with Cheese and Bake
Sprinkle the shredded cheddar cheese generously over the top of the casserole. Place the casserole dish into the preheated oven and cover with foil to retain moisture while baking for 25 minutes. The cheese should melt beautifully, infusing every corner of the casserole with its creamy goodness as it cooks.
Step 9: Broil for Extra Crisp
After 25 minutes, remove the foil and switch your oven to broil. Broil the casserole for 2-3 minutes until the cheese turns golden and bubbly. Keep an eye on it to achieve that perfect crispiness without burning. This final touch will give your Cheesy Chicken Cauliflower Rice Casserole an appetizing golden crust that is sure to impress!
