Batter

Salsa

Additional items

Instructions

Start the Salsa 

  • Preheat the oven to 425°F. Place the tomatoes, onion, and garlic on a parchment-lined sheet pan. Drizzle with oil and roast for about 45 minutes, or until softened and slightly charred. Set aside to cool.

Prep for Casserole

  • Char the poblano peppers on a comal over medium heat, turning until blackened on all sides. Transfer to a bowl, cover with plastic wrap, and let them steam for 10 minutes. Peel off the skins, remove stems and seeds, and set aside uncovered. 
  • In a large nonstick pan, fry the corn tortilla in oil until golden and crispy on both sides. Set aside for the salsa.
  • Lower the heat to medium-low. In the same pan, cook the onions until just softened. Add the chorizo and fully cook, then drain excess fat. Set aside.

Make the Batter

  • In a blender, combine eggs, crema, and melted butter. Blend on medium-high for about 5 minutes until light and bubbly. Transfer to a bowl.
  • Sift in the flour, baking powder, ground onion, and ground garlic. Add salt and gently whisk just until combined—avoid over-mixing.

Prep the Cheese

  • Mix the Oaxaca and cheddar cheeses together. 

Assemble Casserole

  • Preheat oven to 350°F. Grease a 12-inch baking dish with cooking spray.
  • Layer half of the roasted poblanos, followed by the chorizo and half the cheese. Repeat with the remaining peppers and cheese.
  • Lightly whisk the batter again, then pour it evenly over the top. Smooth the surface as much as possible for even baking.
  • Bake for 40–45 minutes, or until the batter is fully cooked, set, and golden on top.

Finish the Salsa

  • Blend the roasted tomatoes, onion, peeled garlic, crispy tortilla, oregano, chipotle peppers, adobo sauce, vinegar, and chicken broth until smooth.
  • Heat 2 tbsp of oil in a small saucepan over medium-low heat. Pour in the salsa and simmer gently for about 3 minutes, stirring occasionally. Season with salt to taste and remove from heat.

Serve

  • Remove the casserole from the oven and let it cool for 10 minutes before serving.
  • Top each serving with warm salsa and chopped cilantro. 
  • Serve with refried beans, Mexican rice, and a side salad for a complete meal.
