Low Carb Chile Relleno Casserole: A Southwestern Comfort Food Classic

The aroma of roasted chiles always transports me back to my grandmother’s kitchen in Santa Fe. She would stand over the stove, coaxing the skins off freshly roasted peppers, the air thick with their smoky fragrance. Chile Rellenos were a special treat, reserved for holidays and family gatherings. While I adore the traditional method, with its labor-intensive stuffing and frying, this casserole offers all the beloved flavors in a much simpler, weeknight-friendly form, perfect for anyone watching their carbs without sacrificing deliciousness.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 35 minutes
• Total Time: 50 minutes
• Servings: 8
• Yield: 1 Casserole
• Dietary Type: Low Carb

Ingredients

• 2 (7 ounce) cans whole green chilies, drained well
• 8 ounces Monterey Jack pepper cheese, shredded
• 3 eggs
• ¾ cup heavy cream
• ½ teaspoon salt
• 4 ounces cheddar cheese, shredded

Equipment Needed

• 8×8 inch baking pan
• Knife
• Mixing bowl
• Whisk

Instructions

1. Begin by preheating your oven to 350°F (175°C). While the oven is heating, grease an 8×8 inch baking pan. This will prevent the casserole from sticking and make serving easier. I like to use a light coating of olive oil or avocado oil spray.

2. Prepare the green chilies. Carefully slice each chile lengthwise along one long side. Open the chiles flat, being careful not to tear them. Draining the chiles well is crucial to prevent a soggy casserole.

3. Arrange half of the sliced green chilies in the bottom of the prepared baking pan. Place them skin side down, creating a single layer that covers the bottom of the pan. This layer acts as the foundation for the cheesy filling.

4. Generously top the layer of chiles with the shredded Monterey Jack pepper cheese. Distribute it evenly, ensuring that every chile is covered with a generous layer of cheese. If you are sensitive to spice, you can substitute plain Monterey Jack cheese.

5. Arrange the remaining green chilies over the cheese layer. Place them skin side up, effectively creating a cheesy filling sandwich between two layers of chiles.

6. In a mixing bowl, prepare the egg mixture. Beat together the eggs, heavy cream, and salt until well combined. This mixture provides the binding and richness to the casserole. Ensure the salt is evenly distributed to enhance the flavors.

7. Pour the egg mixture evenly over the chiles and cheese in the baking pan. Make sure the liquid distributes throughout the casserole to ensure even cooking.

8. Sprinkle the shredded cheddar cheese evenly over the top of the casserole. The cheddar cheese will melt and create a golden-brown crust, adding a lovely visual appeal and a sharp, tangy flavor.

9. Bake in the preheated oven for 35 minutes, or until the casserole is golden brown and set. A toothpick inserted into the center should come out clean. Keep an eye on it, as oven temperatures can vary. If the top starts to brown too quickly, you can loosely tent it with foil.

10. Once baked, remove the casserole from the oven and let it stand for 10 minutes before cutting and serving. This allows the casserole to set properly, making it easier to slice and serve.

Expert Tips & Tricks

• Cheese Choice: Experiment with different types of cheese to customize the flavor profile. Asadero or Oaxaca cheese would be great substitutes for the Monterey Jack. A sprinkle of cotija cheese on top after baking adds a salty, crumbly finish.
• Spice Level: Adjust the heat by adding a pinch of cayenne pepper or a dash of hot sauce to the egg mixture. Alternatively, add some finely diced jalapeños to the cheese layer.
• Make-Ahead Prep: Assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. This is a great time-saver for busy weeknights. You may need to add a few minutes to the baking time if starting from cold.
• Chile Roasting: For an even more authentic flavor, roast your own poblano peppers. Roast under a broiler, on a grill, or over a gas stove flame until the skin is blackened. Place in a bowl and cover with plastic wrap to steam for 10 minutes. Scrape off the skins, remove the seeds, and use in the recipe.

Serving & Storage Suggestions

Serve the Low Carb Chile Relleno Casserole warm, cut into squares. It makes a fantastic main course or a hearty side dish. A dollop of sour cream, a sprinkle of fresh cilantro, and a side of salsa or guacamole elevate the presentation and flavors.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions until warmed through, or reheat the entire casserole in a preheated oven at 350°F (175°C) until heated through. The casserole can also be frozen for up to 2 months. Thaw completely in the refrigerator before reheating.
