• Chopped parsley or cilantro (optional, for garnish)

Instructions

1. Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.

2. Cook the Beef Layer
In a skillet over medium heat, heat olive oil and sauté the onions for 2–3 minutes. Add garlic and cook for another minute. Add ground beef, breaking it up as it browns. Season with chili powder, paprika, cumin, salt, and pepper. Stir in tomato paste (optional) and cook until fully browned and flavorful. Spread cooked beef evenly into the bottom of the baking dish.

3. Prepare the Cheese Egg Mixture
In a mixing bowl, whisk together eggs, cream (or milk), salt, garlic powder, and shredded cheddar and Monterey Jack. Pour this mixture evenly over the beef layer.

4. Add the Top Cheese Layer
Sprinkle the remaining cheese evenly on top. Arrange jalapeño slices across the surface (use fresh for heat or pickled for tangy mild flavor).

5. Bake to Perfection
Bake uncovered for 30–40 minutes, or until the top is golden, bubbly, and set in the center. Let it rest for 5–10 minutes before slicing to allow the layers to settle.

6. Garnish and Serve
Top with chopped parsley or cilantro if desired. Slice and serve warm.
