Some use poblanos in chile rellenos but I never do and never eat them that way. Poblanos are like green bell peppers to me, not enough spicy flavor and never as good as Hatch green chiles. In Hatch they grow green chiles that are all spectrums of heat from milder to very hot. On the Scoville scale, Poblanos are anywhere from 1,500 to 2,500 units. But Hatch Green Chile are 2,000 to 5,000 units. Yep, I do like that spicy! But usually canned whole green chile are milder but have that amazing green chile flavor and are perfect for this relleno dish.

Hatch Chile Relleno Casserole Recipe:
- 27 ounce can of Whole Green Chiles
- 1 pound grated cheddar cheese
- 1 pound grated Monterrey Jack cheese
- 4 eggs, separated, whites and yellows
- 2 cups milk
- 2 Tablespoons flour
Equipment Needed:
- Cooking Spray
- Cheese Grater
- 9 x 13 baking dish
- Mixer
- Aluminum Foil, to cover
🥣 Recipe Tips
- Whip Egg Whites Thoroughly: As noted in the recipe, beat the egg whites until stiff peaks form to achieve a light, fluffy texture. This is crucial for the casserole’s consistency when folding them into the yolk-milk-flour mixture.
- Use High-Quality Hatch Chiles: Opt for canned whole Hatch green chiles for their balanced flavor and mild heat, which are ideal for this dish. Ensure they’re seeded and split open evenly to layer smoothly without gaps.
- Rest Before Serving: Let the casserole rest for at least 10 minutes after baking to allow it to set properly. This makes it easier to cut and serve while keeping the layers intact and the flavors melded.
How to make this Baked Chile Rellenos Casserole:

Preheat your oven to 350° F and grate both cheeses if not already grated and set aside. Spray a 9 x 13 baking dish with non stick cooking spray. Seed the hatch green chiles, split them open and lay ½ of them in the bottom of the baking dish.

Add the grated cheddar cheese on top of the green chiles. It may seem like too much but trust me, it’s perfect.

Layer remaining Hatch green chiles on top of the cheddar adjusting so that there are not empty spots.

Top the hatch green chiles with the pound of grated Jack cheese and even it out in the casserole dish.

Separate egg whites from the yolks with an egg separator and set the egg yolks aside.

Beat the egg whites with a mixer in a separate bowl until stiff and then set aside.
Tip-Also one important tip when making this is to be sure and whip the egg whites well, that makes a great consistency when you gently fold in the remaining ingredients

Add the flour and milk to the egg yolks and mix well. Gently fold the whipped egg whites into the egg yolk, flour, milk mixture.

Gently pour the mixture over top of the Hatch chile relleno casserole and spread it out evenly.

Cover your casserole dish with aluminum foil and place in preheated oven. Bake the casserole for one hour, covered, uncover and bake 5-10 minutes longer to brown.

Remove from oven and allow it to rest for at least 10 minutes before serving.
