Key Ingredients
Poblano Peppers:
Roasted poblanos are the heart of this casserole. They add smoky flavor, gentle heat, and a soft texture that blends beautifully with eggs, sausage, and cheese.
Pork Breakfast Sausage:
Pork sausage gives the casserole a rich, savory base. Its seasoning adds depth and makes the dish feel hearty enough for a full breakfast or brunch.
Extra Sharp White Cheddar Cheese:
Extra sharp white cheddar adds strong cheesy flavor and creamy richness. It melts into the casserole and gives the top a golden, flavorful finish.
Eggs:
Eggs hold the casserole together and create the soft, custardy breakfast texture. They make the dish filling and protein-rich.
2% Milk:
Milk lightens the eggs and helps create a tender texture. It keeps the casserole from becoming too heavy or dense.
Rice Flour:
Rice flour helps thicken the egg mixture slightly and gives the casserole more structure. It also keeps the recipe gluten-free.
Dried Hot Green Chile:
Dried hot green chile adds warmth, spice, and New Mexico-style flavor. It gives the casserole a deeper chile taste without adding extra liquid.
Salt and Black Pepper:
Salt brings out the flavors of the eggs, peppers, sausage, and cheese, while black pepper adds mild warmth.
Green Chile Sauce:
Green chile sauce is optional for serving, but it makes the dish even more flavorful. It adds moisture, heat, and a beautiful finishing touch.
Expert Tips
Roast the poblanos well so the skins blister and the flavor becomes smoky.
Steam the roasted poblanos in a covered bowl or bag before peeling to make the skins easier to remove.
Remove the seeds and stems for a smoother texture and milder flavor.
Drain excess grease from the sausage so the casserole does not become oily.
Use extra sharp cheddar for the strongest flavor.
Whisk the rice flour into the eggs and milk until smooth to avoid lumps.
Pour the egg mixture slowly so it settles evenly into the layers.
Tap the baking dish gently on the counter to help the egg mixture move between the sausage, cheese, and peppers.
Bake until the center is fully set and no longer loose.
Let the casserole rest before slicing so it holds its shape.
For extra heat, add more dried green chile or serve with hot green chile sauce.
For a milder version, use mild sausage and reduce the dried chile.
Poblano Breakfast Casserole with Pork Sausage
Ingredients
3 to 4 large poblano peppers, roasted, peeled, seeded, and sliced
1 pound pork breakfast sausage
1 1/2 to 2 cups shredded extra sharp white cheddar cheese
7 large eggs
1 cup 2% milk
1/4 cup rice flour
1 tablespoon dried hot green chile
1/2 teaspoon salt, or to taste
1/2 teaspoon black pepper
Cooking spray or butter, for greasing the baking dish
Optional for Serving
Breakfast potatoes
Green chile sauce
Sour cream
Chopped cilantro
Warm tortillas
Extra shredded cheddar
Instructions
Preheat the oven to 375°F / 190°C.
Lightly spray or grease a 9×9-inch glass baking dish and set it aside.
Roast the poblano peppers until the skins are blistered and darkened. Place them in a covered bowl or sealed bag for a few minutes to steam, then peel off the skins. Remove the seeds and stems, then slice the peppers into strips or pieces.
In a skillet over medium heat, cook the pork breakfast sausage until browned and fully cooked. Break it into crumbles as it cooks. Drain any excess grease if needed.
Place a layer of roasted poblano peppers on the bottom of the prepared baking dish.
Add an even layer of cooked pork sausage over the poblanos.
Sprinkle the shredded extra sharp white cheddar cheese over the sausage.
In a mixing bowl, whisk together the eggs, milk, rice flour, dried hot green chile, salt, and black pepper until the mixture becomes smooth and slightly thick, like a light slurry.
Pour the egg mixture evenly over the layers in the baking dish. Gently shake the dish or tap it lightly on the counter to help the egg mixture settle between the layers.
Bake uncovered for about 45 to 50 minutes, or until the casserole is puffed, golden brown on top, and fully set in the center.
Remove from the oven and let it rest for 10 minutes before slicing. This helps the casserole firm up and makes it easier to serve.
Serve warm with breakfast potatoes and green chile sauce spooned over the top.
Notes
This casserole is rich, hearty, and full of smoky poblano flavor. The roasted peppers add depth, the pork sausage makes it savory and filling, and the extra sharp white cheddar gives it a bold, cheesy finish.
Rice flour helps the egg mixture set with a slightly firmer texture while keeping the casserole gluten-free.
For a spicier version, add more dried hot green chile or serve with extra green chile sauce. For a milder version, use mild breakfast sausage and reduce the dried chile.
This dish is perfect for weekend breakfast, brunch, meal prep, or a holiday morning casserole.
Important Notes When Making Poblano Breakfast Casserole with Pork Sausage
A 9×9-inch baking dish works well for a thick, hearty casserole.
The casserole may puff up while baking and settle slightly as it cools.
The center should be set before removing it from the oven.
If the top browns too quickly, loosely cover the dish with foil.
Rice flour helps with structure, but it should be whisked well into the liquid mixture.
Pork sausage can be salty, so adjust added salt carefully.
Roasted poblanos are usually mild, but heat levels can vary.
Letting the casserole rest for 10 minutes makes slicing much easier.
This dish is excellent for meal prep and reheats well.
Store leftovers covered in the refrigerator.
Serve with sauce after baking, not before, so the casserole does not become watery.
How to Enjoy Poblano Breakfast Casserole with Pork Sausage After Cooking
After the Poblano Breakfast Casserole comes out of the oven, let it rest for about 10 minutes. This resting time helps the eggs finish setting and allows the layers of poblano, sausage, cheese, and egg to hold together when sliced.
Cut the casserole into squares and serve it warm. Each slice should have smoky roasted poblano, savory sausage, melted cheddar, and a golden egg base.
For a classic breakfast plate, serve it with crispy breakfast potatoes on the side. The potatoes add crunch and make the meal feel complete and comforting.
For extra flavor, spoon warm green chile sauce over the top. The sauce adds heat, moisture, and a beautiful Southwestern finish that works perfectly with the poblanos and sausage.
You can also serve this casserole with sour cream, chopped cilantro, avocado slices, salsa, warm tortillas, or extra shredded cheddar. Warm tortillas are especially good if you want to turn the casserole into breakfast tacos.
For brunch, pair it with fresh fruit, a simple salad, roasted potatoes, beans, coffee, or orange juice. The richness of the sausage and cheese pairs well with something fresh or bright on the side.
Leftovers can be reheated in the microwave, oven, or air fryer. For the best texture, reheat gently until warm, then add green chile sauce or salsa right before serving.
