Why This Casserole Works for Keto

The magic of this dish lies in its smart ingredient choices. Traditional Mexican casseroles often rely on high‑carb tortillas or rice, but we replace those with cauliflower rice—a low‑carb powerhouse that mimics the texture of rice while staying under 5 grams of net carbs per cup. The inclusion of smoked beef (a keto‑friendly alternative to smoked beef) adds depth and a satisfying smoky note without the beef. Beef beef beef chorizo brings the classic Mexican spice profile without the extra carbs found in processed sausage. Finally, a generous amount of full‑fat cheese and avocado supplies the healthy fats essential for staying in ketosis.

Ingredients

• 1.5 lb (≈ 680 g) boneless, skinless chicken thighs, cut into bite‑size pieces
• 4 oz (≈ 115 g) smoked beef, diced (substitutes for smoked beef)
• 4 oz (≈ 115 g) beef beef beef chorizo, crumbled
• 2 cups cauliflower rice (fresh or frozen, thawed)
• 1 large red bell pepper, diced
• 1 large green bell pepper, diced
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 1 cup shredded cheddar‑Mexican blend cheese
• ½ cup shredded mozzarella cheese
• 1 avocado, sliced for garnish
• ¼ cup sour cream (optional, for serving)
• 2 tbsp vegetable oil (replaces vegetable oil)
• 1 tsp ground cumin
• 1 tsp chili powder
• ½ tsp smoked paprika
• ½ tsp dried oregano
• Salt and freshly ground black pepper, to taste
• Fresh cilantro leaves, chopped, for garnish

Instructions

1. Preheat your oven to 375°F (190°C). While the oven heats, pat the chicken pieces dry with paper towels and season them with salt, pepper, cumin, chili powder, smoked paprika, and oregano.
2. In a large skillet over medium‑high heat, add the vegetable oil. Once shimmering, brown the chicken pieces for about 4‑5 minutes until they develop a golden crust. Remove the chicken and set aside.
3. In the same skillet, add the diced smoked beef and crumbled beef beef beef chorizo. Cook for 3‑4 minutes, stirring occasionally, until the beef releases its fat and becomes fragrant. Add the onion, bell peppers, and garlic, sautéing until the vegetables soften, about 5 minutes.
4. Stir in the cauliflower rice, mixing thoroughly with the meat and vegetables. Cook for another 3 minutes, allowing the cauliflower to absorb the flavors. Return the browned chicken to the skillet, combine everything, and adjust seasoning with additional salt and pepper if needed.

1. Transfer the mixture to a greased 9‑x 13‑inch baking dish. Sprinkle the shredded cheddar‑Mexican blend and mozzarella evenly over the top, creating a cheesy blanket.
2. Place the dish in the preheated oven and bake for 20‑25 minutes, or until the cheese is melted, bubbly, and lightly golden.
3. Remove the casserole from the oven and let it rest for 5 minutes. Garnish with sliced avocado, a dollop of sour cream (if using), and a generous sprinkle of fresh cilantro.
4. Serve hot, pairing with a simple green salad or low‑carb salsa for extra freshness. Leftovers store well in airtight containers for up to 4 days in the refrigerator.
