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:

• Use Pepper Jack for extra kick.
• Whole milk keeps custard tender.
• Freshly shredded cheese melts best.
• Split chiles for even filling.
• Room-temp eggs blend more smoothly.

How to Make It

1. First, preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish so the casserole won’t stick.
2. Next, spread the drained and split green chiles in a single layer across the bottom; you should still see some green peeking through.
3. Then, scatter the shredded Monterey Jack (or Pepper Jack) and cheddar over the chiles in an even layer; press slightly so cheese nests into the peppers.
4. Meanwhile, whisk eggs, milk, heavy cream, flour, baking powder, salt, pepper, garlic powder, and onion powder until smooth and a bit frothy.
5. Pour the egg mixture slowly over the cheese, moving the dish a little so the custard seeps down and covers the chiles evenly. You’ll hear a quiet settle and see the custard fill gaps.
6. Bake for about 45 minutes, or until the top turns golden and the center no longer jiggles — a knife in the middle should come out mostly clean.
7. Finally, let it rest for 10 minutes so the custard firms and slices hold together; then scoop warm portions and enjoy the steam and aroma.

Also, if the edges brown too fast, tent loosely with foil during the last 15 minutes.

Kitchen Tips (From My Kitchen)

1. Time-saver: Use pre-shredded cheese, but expect slightly less melt — toss it with a pinch of flour.
2. Common mistake + fix: If the custard is runny, bake a bit longer and check center with a knife; underbaking causes weeping.
3. Simple variation: Stir in chopped cilantro or serve with salsa verde for brightness.

Serving Ideas

• Weeknight dinner: Pair with a crisp green salad and lime wedges.
• Brunch: Serve with fried eggs on top and hot sauce on the side.
• Holiday side: Offer alongside roasted pork or turkey for a creamy contrast.
• Garnish ideas: Cilantro, sliced scallions, or a dollop of sour cream.

Storing & Leftovers

• Fridge: Store covered up to 4 days.
• Freezer: Freeze portions up to 2 months; thaw overnight in fridge.
• Reheat: Warm covered in a 325°F oven until heated through to keep texture.
  Leftover idea: Stuff slices into a warm tortilla for a cheesy wrap.

FAQs

Q: Can I make this ahead?
A: Yes — assemble, cover, and refrigerate up to 24 hours; add 5–10 minutes to baking time when cold.

Q: Can I swap cheeses?
A: Absolutely — try a mix of pepper jack and monterey for spice, or all cheddar for milder flavor.

Q: How do I know it’s done?
A: The edges will be golden and the center should be mostly set with a gentle wobble.

Q: Can I freeze Creamy Chile Relleno Casserole?
A: Yes, freeze baked slices in a single layer, then stack with parchment. Reheat from thawed for best texture.
