HOW TO MAKE Low Carb Chicken Taco Casserole

This casserole is easy to assemble. You mix the cooked chicken with the cauliflower rice and the other filling ingredients. Then you bake it until hot and bubbly. The top gets golden and the sides stay moist. You can make the mixture ahead and bake it when you are ready, or bake it and reheat later.

Follow the ingredient list and steps below for a clear path. If you like to shorten prep time, shred chicken or use pre-shredded items. Try to keep cauliflower rice well drained if it was frozen so the casserole does not get watery. For crisp edges, use a glass or ceramic dish. If you want a faster weeknight meal, this dish goes well with a crisp salad and plain Greek yogurt on the side.

For a tropical twist on chicken dinners, you can try flavors like in 30-minute pineapple chicken coconut rice, which uses fruit and coconut for a very different but simple meal idea.

EQUIPMENT NEEDED

• 9×13-inch (23×33 cm) baking dish
• Large mixing bowl
• Spoon or spatula for mixing
• Measuring cups and spoons
• Oven mitts
• Knife and cutting board for the green onions and cilantro
• Optional: grater for fresh cheese

Ingredients You’ll Need :

• 2 cups cooked chicken, shredded
• 1 cup cauliflower rice (fresh or frozen, thawed)
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup diced tomatoes with green chilies (such as Rotel), undrained
• 1 cup shredded cheddar cheese, divided (¾ cup for topping, ¼ cup can be mixed in if desired)
• 1/2 cup sour cream
• 1 tablespoon taco seasoning (store-bought or homemade)
• 1/2 cup green onions, chopped
• 1/4 cup fresh cilantro, chopped
• Salt and black pepper, to taste
• Nonstick cooking spray or a little oil, for greasing the baking dish

STEP-BY-STEP INSTRUCTIONS :

1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch (23×33 cm) baking dish with nonstick spray or a little oil.
2. In a large mixing bowl, add the shredded chicken, cauliflower rice, black beans, diced tomatoes with green chilies, taco seasoning, and sour cream.
3. Stir everything together until the chicken and veggies are evenly coated in the creamy taco mixture. If you like it extra cheesy, stir in 1/4 cup of the shredded cheddar at this stage.
4. Taste the mixture, then season with salt and black pepper to your liking. Remember the taco seasoning and cheese also add salt, so go gradually.
5. Transfer the chicken mixture into the prepared baking dish and spread it out into an even layer, pressing gently with the back of a spoon or spatula.
6. Sprinkle the remaining shredded cheddar cheese evenly over the top of the casserole.
7. Scatter the chopped green onions and half of the cilantro over the cheese layer, reserving the remaining cilantro for garnish after baking.
8. Bake in the preheated oven for 25–30 minutes, or until the casserole is hot throughout and the cheese on top is fully melted, bubbly, and lightly golden around the edges.
9. Remove the casserole from the oven and let it rest for 5–10 minutes. This helps it set up slightly so it slices and serves more neatly.
10. Garnish with the remaining cilantro, then scoop into bowls or onto plates and serve warm.

HOW TO SERVE Low Carb Chicken Taco Casserole

Serve this casserole warm. Use a spatula to scoop neat portions onto plates. Add a spoonful of salsa or a dollop of sour cream on top for extra creaminess. You can add slices of avocado or a few wedges of lime for bright flavor. A small side salad of lettuce, tomatoes, and cucumber keeps the meal light and fresh.

If you want a low carb wrap, spoon a portion into a large lettuce leaf and fold it like a taco. For family meals, place the casserole in the center of the table with bowls of toppings so each person can add their own extras. For a casual dinner, pair the casserole with a simple bowl of steamed vegetables.

If you plan an evening with more chicken dishes, a fun add-on is to serve this after or before a lighter dish like the seasonal drinks in 14 spooky Halloween milkshakes for a themed night.

STORAGE & FREEZING : Low Carb Chicken Taco Casserole

To store leftovers, let the casserole cool to room temperature, then cover the dish tightly or move portions into airtight containers. Refrigerate for up to 3–4 days. Reheat in the oven at 325°F (160°C) until hot, or warm single servings in the microwave for 1–2 minutes.

To freeze, cool the casserole completely. Wrap the baking dish in plastic wrap and then foil, or transfer portions into freezer-safe containers. Freeze for up to 2 months. To reheat from frozen, thaw overnight in the fridge and then bake at 350°F (175°C) for 20–30 minutes, until hot throughout. If you reheat from fully frozen, increase bake time and cover loosely with foil to prevent the top from burning.

If you plan to freeze, skip fresh toppings like chopped green onions and cilantro until after reheating. Add fresh herbs when you serve for bright flavor.

SERVING SUGGESTIONS

• Top with a spoon of sour cream or Greek yogurt and a few slices of avocado.
• Serve with lime wedges for a fresh squeeze of juice.
• Add a side of sautéed bell peppers and onions for color and crunch.
• Offer small bowls of pico de gallo, hot sauce, or pickled jalapeños for guests to choose from.
• Place a serving of mixed greens or a simple cabbage slaw on the side to add texture.

VARIATIONS

You can change this casserole to fit your needs without changing the base idea.

• Dairy-free: Use a dairy-free sour cream and dairy-free cheese. The texture will be a bit different but still tasty.
• Extra low carb: Omit the black beans to cut carbs further and add more cauliflower rice.
• Spicy: Add a chopped jalapeño or a pinch of cayenne to the mix for heat.
• Cheesy bake: Stir in the extra 1/4 cup cheese into the filling and top with a full cup of cheese for an even richer bake.
• Vegetable boost: Add chopped bell peppers, zucchini, or corn if you want more veggies. Note corn adds carbs.
• Make it a taco skillet: Skip the baking dish, mix everything in a large oven-safe skillet, and broil the top for a minute to brown the cheese.

For a menu with drinks and other fun items, pair this casserole with fall treats or themed drinks such as the ones in 15 spooktacular Halloween mocktails for a family party night.

FAQs

Q: Can I use fresh cauliflower rice instead of frozen?
A: Yes. Fresh cauliflower rice works well. Make sure it is not very wet. If it seems damp, press it with a paper towel to remove extra liquid.

Q: Is this dish really low carb with black beans?
A: Black beans add some carbs, but they also add fiber and protein. If you want fewer carbs, leave the beans out or cut the amount in half.

Q: Can I make this in a smaller dish?
A: Yes. If you use a smaller dish, the casserole will be thicker and may need a few extra minutes in the oven. Watch the top so it does not burn.

Q: Can I use taco-seasoned ground beef instead of chicken?
A: Yes. Cook the ground beef first, then mix it with the other ingredients. The bake time stays about the same.

Q: How can I reheat a single portion?
A: Microwave for 1–2 minutes on high or warm in a small skillet over low heat until hot. You can also use an oven at 325°F (160°C) for 10–15 minutes.

Q: Can I replace the cheddar with another cheese?
A: Yes. Monterey Jack, pepper jack, or a Mexican blend work well and change the flavor a little.
