Step-by-Step Instructions to Make Poblano Pepper and Cheese Casserole

1. Roasting the Poblano Peppers

The key to unlocking the rich, smoky flavor of poblano peppers is roasting them properly. Preheat your oven’s broiler and arrange the halved peppers, skin side up, on a lightly oiled baking sheet. Broil them for about 10 minutes until the skins blacken and blister, and the peppers puff slightly.

Once they’re charred, give them time to cool just enough to handle. Then, carefully peel away the skins — this step is crucial for smooth texture and to avoid any bitterness. Remove the seeds and stems, and slice the peppers into strips or chop them, depending on your preference.

Pro tip: Roasting the peppers over an open flame on a gas stove can also work if you want an extra smoky flavor.

2. Preparing the Tomato Sauce

While your peppers are roasting, heat the olive oil in a 10-inch ovenproof skillet over medium heat. Add the chopped onion and jalapeño and sauté until softened, about five minutes. The jalapeño adds a subtle heat to the sauce, but you can omit or adjust it to suit your spice tolerance.

Next, toss in the garlic and cook for another minute until fragrant. Then, add the chopped tomatoes along with Mexican oregano, paprika, ancho powder, cumin, salt, and pepper. Use a spoon to break apart the tomatoes, stirring everything together.

Let the mixture simmer on medium-low heat for about 10 minutes, stirring occasionally. You want the sauce to thicken and the flavors to meld. If you prefer a thicker sauce, you can simmer it a bit longer.

Once the sauce reaches the right consistency, transfer it to a glass bowl to prepare for layering.

3. Assembling the Casserole

Preheat your oven to 350°F (175°C) as you prepare to layer your ingredients.

In the same skillet (or transfer to a baking dish if preferred), spread half of the tomato sauce evenly over the bottom. Then, add half of your roasted poblano strips over the sauce. Sprinkle half of the shredded cheese across the peppers to create a rich, melty layer.

Repeat the layering with the remaining tomato sauce, roasted poblano strips, and most of the remaining cheese, leaving a small amount of cheese for the topping.

4. Adding the Egg and Cheese Topping

In a bowl, beat the four eggs and mix them with the leftover shredded cheese. This mixture adds creaminess and helps bind the casserole together as it bakes.

Pour the egg and cheese mixture evenly over the assembled layers in the skillet or baking dish.

5. Baking to Perfection

Place the casserole in the preheated oven and bake for 25 minutes, or until the eggs have set and the cheese on top is melted, bubbly, and slightly golden.

If you want a crispier top, you can finish under the broiler for 1-2 minutes, but watch carefully to avoid burning.

6. Garnishing and Serving Suggestions

Once baked, remove your casserole from the oven and let it cool slightly. Garnish with a sprinkle of spicy chili flakes for a pop of heat and fresh herbs like cilantro, parsley, or chives to brighten the dish.

This casserole pairs beautifully with warm tortillas, a side of rice, or a crisp green salad to round out your meal.
