This Poblano Chorizo Breakfast Casserole layers smoky roasted poblanos, spicy chorizo, and melty cheese into a rich, custardy bake that’s perfect for brunch.

It’s technically a strata, which just means everything’s layered and soaked in an egg mixture before baking. The result? A make-ahead casserole that’s rich, savory, and perfect for casual mornings or a no-fuss weekend brunch.

Here’s Why This Chorizo Breakfast Casserole Recipe Works

Smoky roasted poblanos: Charring the chiles brings out a deep, earthy sweetness that plays perfectly against the spicy chorizo.

Cheese with attitude: Pepper Jack melts creamy but adds a little kick, so the casserole isn’t one-note cheesy.

Overnight ease: Assemble it ahead so the bread drinks in the custard, then by morning, all you do is bake.

Feeds a crowd, travels well: Ideal for brunch buffets, potlucks, or holiday mornings since it reheats beautifully.

Recipe Tips

Start with stale bread: Day-old or oven-dried cubes soak up the custard better.

Roast poblanos well: Broil until the skins blister and blacken for maximum smoky depth.

Drain the chorizo: Spoon off excess grease so the casserole bakes rich, not oily.

Spray the foil: A light coat of oil keeps the melted cheese from sticking when you uncover it.

Rest before slicing: A 10-minute cool-down helps the strata set so it cuts into neat portions.

Swap if needed: No poblanos? Use roasted bell peppers. Can’t find chorizo? Try spicy Italian sausage.

Ingredients 

  • 1 tablespoon olive oil
  • 6 Poblano chili peppers
  • 1 ¼ pounds stale bread, crusts removed, approximately 1 large loaf of French bread
  • 10 large eggs
  • 3 cups whole milk
  • 8 ounces cream cheese, cut into chunks
  • 1 tablespoon chipotle aioli
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 1 teaspoon ground cumin
  • 1 ½ pound ground chorizo sausage
  • 3-4 shallots, sliced
  • 3 garlic cloves, grated or minced
  • 1 deli roasted red bell pepper, sliced in strips
  • 8 ounces Pepper Jack cheese
  • ½ cup chopped cilantro
  • 2 ounces Parmesan cheese, grated

Instructions 

  • Coat a 9x13x2-inch oven proof casserole dish with oil spray.

Roast the Poblano peppers:

  • Brush the Poblano peppers with the olive oil and place on a foil-lined baking sheet.  Set the oven control to ‘broil’ with the top rack positioned 4-6 inches from the unit. 
    Broil the peppers for 5 minutes until the skin blisters and chars.  Pull the rack out and flip the peppers and broil the second side for an additional 5 minutes until the skin is blistered and charred.
  • Transfer the baking sheet to a work space and cover with another piece of foil.  Let the peppers steam and ‘sweat’ for 10 minutes.  When cool enough to handle, lift the skins off and discard. 
    Cut the peppers in half, remove and discard the seeds, veins and the stem; then slice the peppers lengthwise, into 1-inch strips.  Place the strips on a plate and reserve until needed.

Mix the Custard:

  • To the bowl of a food processor or blender, add the eggs, milk, cream cheese, salt, pepper, aioli and cumin.  Pulse the mixture until smooth.  Set aside.  

Prepare the Ingredients:

  • Place the bread cubes in a large bowl and set aside.
  • In another bowl add the Pepper Jack cheese and the cilantro, toss to combine.  Set aside.
  • In a large skillet set over medium heat, add the chorizo and cook until lightly browned, breaking it up with a fork as it cooks.  Spoon off and discard as much of the accumulated fat as possible. 
    Push the chorizo to the edge of the skillet and add the sliced shallots and red bell pepper.  Sauté until the shallots are slightly softened.  Add the garlic and cook until fragrant, about 30 seconds. Stir the chorizo and shallots, red pepper and garlic together and remove the skillet from the heat and set aside. 
  • Shred the Pepper Jack cheese into a large bowl, add the chopped cilantro, toss together and set the bowl aside.

Assemble the Strata:

  • Coat a 9x13x2-inch oven-proof casserole dish with oil spray.
  • Place ½ of the bread cube in the bottom of the prepared dish.  Pour ⅓ of the milk mixture over the bread cubes.
  • Add ½ of the chorizo mixture over the bread cubes and ½ of the Pepper Jack cheese and ½ of the Poblano slices.  With a spatula, press down gently on the layer. 
  • Continue layering with the remaining bread, ⅓ of the milk mixture, the remaining chorizo mixture and Pepper Jack cheese and the last of the Poblano slices.  Again, press the layer down gently.
  • Pour the last of the milk mixture and distribute the grated Parmesan cheese evenly over the top.  
  • Spray one side of a sheet of foil with non-stick oil spray, cover the casserole, oil side down and transfer to the refrigerator overnight.
  • When ready to bake the strata, transfer from the oven to the counter top while the oven heats. 
  • Heat the oven to 350°F and bake the strata for 40 minutes covered with the foil, then remove the foil and continue to bake for another 20-25 minutes until the strata is golden brown and a little crisp around the edges.
  • Transfer from the oven and cool for 10 minutes on a wire rack before serving.

Notes

Measure the bread: You’ll need about 7–8 cups of lightly packed cubes.
Choose bulk chorizo: Widely available in most supermarkets and easy to crumble into the mix.
Drain the fat: Spoon off excess grease after cooking the chorizo. If fat rises to the top after baking, blot with a paper towel.
Chill overnight: Refrigerating before baking gives the bread time to fully soak up the custard.
Don’t freeze raw strata: Only freeze after baking (up to 3 months).
Storage tips: Leftovers keep 3–4 days in the fridge or can be frozen for later.
