Keto and casseroles seem to go hand in hand when you think about the type of high-fat foods that are being included. All of the cheeses you’re able to use create an ooey, gooey texture that everyone can enjoy. Whether you’re a working mom, a college student, or you just want an easy meal – this casserole will get the job done!
This is my Southwestern-esque take on Shepherd’s Pie. It’s got a great heat coming through from the chili seasoning, a good balance of acidity and sweetness from the tomatoes, and plenty of cheese to boot. The cauliflower on top just adds a layer of fluffy goodness that lightens up what might be considered a heavy dish.
One tip to make things go a little quicker is to pre-cook the cauliflower when you start browning the chicken. It will still be warm enough to melt the cheese into the cauliflower, and will save on 5-6 minutes of down time while you’re cooking. This way, you can have everything ready in just about 30 minutes.
Yields 6 servings of Nacho Chicken Casserole
The Preparation
- 28 ounces boneless, skinless chicken thighs
- salt and pepper, to taste
- 1 1/2 teaspoons chili powder
- 2 tablespoons olive oil
- 4 ounces cream cheese
- 1/4 cup sour cream
- 3 tablespoons parmesan cheese
- 4 ounces cheddar cheese, shredded
- 1 cup canned tomatoes with green chiles, such as Ro-Tel
- 16 ounces frozen cauliflower
- 1 medium jalapeno pepper
The Execution
1. Pre-heat oven to 375F. Using kitchen shears, chop chicken into bite-size chunks. Season chicken with salt, pepper, and chili seasoning.
2. Over medium-high heat, cook chicken in olive oil until browned on all sides.
3. Add cream cheese, sour cream and 3/4 of the cheddar cheese to the chicken, then stir together until melted and mixed. Add tomatoes and green chili and mix well.
4. In a casserole dish, add chicken mixture from the pan.
5. Microwave frozen cauliflower until cooked through. Use an immersion blender to blend with remaining cheddar cheese and parmesan into a mashed potato-like consistency. Season with salt and pepper.
6. Cut a jalapeno into chunks. Spread cauliflower mixture over the top of the casserole, then sprinkle jalapeno pepper over the top. Bake for 15-20 minutes or until some color is on the top and the jalapenos are cooked.
7. Slice and serve. Some fresh chopped cilantro tastes great over the top!
