It’s easy to customize (swap turkey sausage, make it vegetarian, go dairy-free) and it reheats beautifully for busy weekdays.

- 1 teaspoon ground cumin
- 1/2 teaspoon smoked paprika

How to Make Breakfast Green Chili Casserole
Time needed: 1 hour
- Prep and cook the base
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with a little butter or nonstick spray. If you’re using hash browns, spread them evenly in the bottom of the dish and press down slightly. If you prefer cubed bread, roughly toss the cubes with a tablespoon of melted butter and press them into the dish.
- Sauté the aromatics
In a skillet over medium heat, warm the olive oil. Add the chopped onion and cook until soft and translucent, about 4 minutes. Add the breakfast sausage, breaking it up with a spoon, and cook until browned and cooked through. If you’re making the vegetarian version, sauté the bell pepper until soft and stir in the black beans to warm through. Stir in the drained green chiles and remove from heat.
- Mix the custard and assemble
In a large bowl, whisk together the eggs, milk, cumin, paprika, salt and pepper. Sprinkle half of the cheddar over the potato or bread base, then distribute the sausage and chile mixture evenly. Slowly pour the egg mixture over everything so it settles into the nooks. Top with the remaining cheddar.
- Bake and finish
Bake for 35–45 minutes, or until the top is puffed and golden and a knife inserted into the center comes out mostly clean. Let it rest for 10 minutes—the casserole will set and be easier to slice. Finish with chopped cilantro and green onions or jalapeño for a fresh contrast.
Serving suggestions
Serve this with simple sides: a bright green salad, sliced avocado, or a bowl of fresh fruit to cut through the richness. Leftovers are fantastic reheated in the oven or microwave, and the flavors often improve overnight as they meld. If you want something lighter, consider pairing it with Coffee Pancakes.
Notes
- Make it ahead: Assemble and refrigerate up to 24 hours before baking.
- Freeze-friendly: Bake, cool, and freeze in portions for easy breakfasts—reheat in a 350°F oven until warmed through.
- Texture tip: If you like a crispier top, broil for 1–2 minutes at the end—watch closely so it doesn’t burn.
- Dairy-free swap: Use a plant-based milk and dairy-free cheese to adapt the recipe.
FAQs
Yes—assemble the casserole, cover it tightly, and refrigerate overnight. Add 5–10 minutes to the baking time if you chill it before baking. This is the ultimate make-ahead breakfast for busy mornings or brunch hosting.
You can swap sausage for diced ham, cooked bacon, or make it vegetarian with sautéed mushrooms and black beans. For a lighter option, use turkey sausage.
Use hash browns as the base (check the package to ensure they’re gluten-free) and avoid bread—then yes, it can be gluten-free. Also confirm any processed ingredients, like sausage, are labeled gluten-free.
That depends on the chiles you choose. Canned mild green chiles add brightness with little heat; pick the hot variety or add chopped jalapeño if you want more kick.
