Ingredients You’ll Need

• 2 (7-ounce) cans whole green chiles, drained and split open
• 2 cups shredded Monterey Jack or Pepper Jack cheese
• 1 cup shredded cheddar cheese
• 4 large eggs
• 1 cup whole milk
• 1/2 cup heavy cream
• 1/4 cup all-purpose flour
• 1/2 teaspoon baking powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon garlic powder
• 1/4 teaspoon onion powder

Chef notes:

• Monterey Jack = milder, oozy melt.
• Pepper Jack = adds gentle heat.
• Whole milk keeps the custard rich.
• Drain chiles well to avoid sogginess.
• Use fresh-shredded cheese for best melt.

How to Make It

1. First, preheat the oven to 350°F (175°C). Grease a 9×13-inch dish so the casserole releases easily.
2. Next, whisk eggs, milk, heavy cream, flour, baking powder, salt, pepper, garlic powder, and onion powder until smooth and slightly aerated. The mixture should coat the back of a spoon.
3. Then, layer half the drained, split-open chiles in the bottom of the dish so pockets face up; you’ll get little cheese pockets as it bakes.
4. After that, sprinkle half the Monterey Jack, then half the cheddar over the chiles. Press lightly so cheese nestles into the chiles.
5. Meanwhile, pour half the egg mixture evenly over the first layers; you should see the custard fill gaps and surround the chiles.
6. Repeat layers with remaining chiles and cheeses, then pour the rest of the egg mixture on top. Smooth with a spatula.
7. Finally, bake 45 minutes or until the top is set and edges turn golden. The center should jiggle faintly but not be runny. Let rest 10 minutes; the custard will finish setting and slice cleanly.
8. Serve warm. For a corn-studded twist, I often borrow a simple technique from my cheesy scalloped corn casserole to add texture.

Kitchen Tips (From My Kitchen)

1. Time-saver: Use pre-shredded cheese but toss it in a little flour to prevent clumping.
2. Common mistake + fix: If the center stays very wet, tent with foil and bake 10–15 minutes longer; this prevents over-browning while finishing the custard.
3. Simple variation: Stir in 1/2 cup roasted corn or chopped cilantro for brightness.

Serving Ideas

• Weeknight dinner: pair with a simple green salad and warm tortillas.
• Brunch: serve with fried eggs and salsa on the side.
• Holiday side: slice and place next to roasted meats for a creamy contrast.
• Game day: cut into squares and offer toothpicks for easy sharing.
  
  Garnish ideas: chopped cilantro, a squeeze of lime, or a drizzle of crema. Also try it as a hearty filling for a hot sandwich like a savory casserole melt: a chicken-biscuit-style stack works well.

Storing & Leftovers

• Fridge: Store covered up to 4 days; cool before sealing.
• Freezer: Freeze portions up to 2 months in airtight containers.
• Reheat: Warm gently in a 350°F oven until heated through to keep texture.
  
  Leftover idea: Chop and fold into a breakfast scramble or a hearty sandwich.
