Instructions

Phase 1: Prep & Preheat (Time: 5 Minutes | Intensity: Low)

1. Preheat the Oven: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray.

2. Prep the Ingredients: Dice the onion, mince the garlic, slice the green onions, and chop the cilantro. Set aside.

Phase 2: Cook the Beef Layer (Time: 10 Minutes | Intensity: Medium-High)

1. Brown the Beef: Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until fully browned (about 6-8 minutes). Drain any excess grease, leaving about 1 tablespoon in the pan for flavor.

2. Sauté Aromatics: Add the diced onion and minced garlic to the skillet. Cook for 2-3 minutes until softened and fragrant.

3. Season: Stir in the taco seasoning, chili powder, cumin, smoked paprika, salt, and pepper. Add the diced green chiles with their liquid. Cook for another 2 minutes, stirring constantly, until the mixture is well coated and fragrant.

4. Remove from Heat: Remove the skillet from the heat and set aside.

Phase 3: Prepare the Casserole Base (Time: 3 Minutes | Intensity: Low)

1. Whisk the Eggs: In a medium mixing bowl, whisk together the eggs, heavy whipping cream, sour cream, garlic powder, onion powder, salt, and pepper until smooth and fully combined.

Phase 4: Assemble the Casserole (Time: 5 Minutes | Intensity: Low)

1. First Layer (Beef): Spread the seasoned ground beef mixture evenly across the bottom of the prepared baking dish.

2. Second Layer (Cheese): Sprinkle 1 ½ cups of shredded cheddar cheese evenly over the beef.

3. Third Layer (Egg Mixture): Pour the egg and cream mixture evenly over the cheese and beef. Tilt the dish gently to ensure the mixture spreads evenly.

4. Fourth Layer (Toppings): Sprinkle the remaining ½ cup of cheddar cheese and the Monterey Jack cheese over the top. Scatter the sliced black olives and diced tomatoes over the cheese.

Phase 5: Bake (Time: 30-35 Minutes | Intensity: Low)

1. Bake: Transfer the baking dish to the preheated oven and bake for 30 to 35 minutes, until the center is set and a knife inserted into the middle comes out clean.

2. Broil (Optional): For a golden, bubbly top, switch the oven to broil for the last 2-3 minutes. Watch carefully to prevent burning.

3. Rest: Remove from the oven and let the casserole rest for 5-10 minutes before slicing. This allows the layers to set and makes serving easier.

Phase 6: Garnish & Serve (Time: 2 Minutes | Intensity: Low)

1. Garnish: Sprinkle the sliced green onions and chopped fresh cilantro over the top of the casserole.

2. Serve: Slice into 6 equal portions and serve with sour cream, guacamole, salsa, or hot sauce on the side.

Flavor Variations

• Spicy Keto: Use pepper jack cheese instead of Monterey Jack and add a diced jalapeño to the beef mixture for extra heat.

• Chicken Taco Casserole: Substitute the ground beef with 3 cups of shredded cooked chicken. Reduce the taco seasoning to 1 tablespoon.

• Veggie-Packed: Add 1 cup of sautéed zucchini, cauliflower rice, or spinach to the beef layer for extra nutrients.

• Creamy Jalapeño: Add 4 oz of softened cream cheese and 2 diced jalapeños to the beef mixture for a creamy, spicy twist.

• Dairy-Free: Substitute the heavy cream with full-fat coconut milk, the sour cream with a dairy-free alternative, and use dairy-free shredded cheese.
