Equipment

  • 9×13-inch baking dish
  • Large skillet
  • Large mixing bowl
  • Medium mixing bowl
  • Whisk
  • Cutting board
  • Sharp knife
  • Measuring cups and spoons

Ingredients

Base

  • 1 30–32 oz bag frozen shredded hash browns thawed and patted very dry
  • 1 lb Hatch green chile sausage OR pork sausage
  • ½ cup roasted Hatch green chiles only if using plain sausage
  • 1 cup corn thawed & dried OR drained if canned
  • 1 15 oz can black beans rinsed and drained
  • 1 medium onion diced
  • 1–2 jalapeños seeded and minced (optional)
  • 3 cloves garlic minced
  • ½ cup chopped fresh cilantro
  • 1 cup shredded pepper jack cheese
  • 1 cup shredded sharp cheddar cheese

Creamy Binder

  • 1 cup sour cream
  • ¾ cup heavy cream or whole milk
  • ¾ cup Hatch green chile enchilada sauce
  • 2 large eggs
  • 1 tsp smoked paprika
  • 1 tsp cumin
  • ½ tsp chili powder
  • ½ tsp onion powder
  • ½ tsp garlic powder
  • 1 tsp lime juice
  • Salt & pepper to taste

Topping

  • 1–1½ cups shredded pepper jack and cheddar cheese
  • Fresh cilantro for garnish
  • Sliced green onion optional

Instructions

Preheat

  • Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.

Prep Ingredients

  • Pat the thawed hash browns very dry with paper towels. Let the beans drain for 2–3 minutes and make sure the corn is thawed and dry.

Cook Sausage

  • In a large skillet over medium heat, brown the sausage until fully cooked. Add the diced onion and cook until soft and translucent. Stir in the jalapeño and cook for 1–2 minutes, then add the garlic and cook for 30–60 seconds. Drain excess grease, leaving about 1 tablespoon, and let the mixture cool for 5 minutes.

Mix Base

  • In a large bowl, combine the hash browns, corn, black beans, and cilantro, then toss to distribute evenly. Add the sausage mixture along with the pepper jack and cheddar cheese, and mix gently.

Make Binder

  • In a separate bowl, whisk together the sour cream, cream or milk, enchilada sauce, eggs, spices, lime juice, salt, and pepper until completely smooth.

Combine

  • Pour the binder into the mixture in two additions, folding gently after each addition until evenly coated. The mixture should be thick and creamy, not watery.

Assemble

  • Transfer the mixture to the prepared baking dish, filling no more than three-quarters full, and spread evenly. Top with the remaining cheese.

Bake

  • Bake for 40–50 minutes, rotating the pan halfway through, until the center is set, the edges are bubbling, and the top is golden. If the top browns too quickly, loosely tent with foil.

Rest

  • Let the casserole rest for 15 minutes before slicing.

Finish

  • Top with fresh cilantro, green onion, and a light squeeze of lime, then slice and serve.

Notes

Dry the Hash Browns Well

For best results, make sure the hash browns are completely thawed and thoroughly dried before mixing. Excess moisture is the main cause of a watery casserole, so press them well with paper towels.

Control Moisture from Add-Ins

If using frozen corn, thaw and pat it dry before adding. If using canned corn, drain it well. Let the black beans sit in a strainer for a few minutes after rinsing to remove excess water.

Choose the Right Sausage

This recipe works with either Hatch green chile sausage or plain pork sausage. If using plain sausage, add roasted Hatch green chiles for flavor. Do not use both together, as it can make the casserole too wet and overpower the balance.

Use Freshly Shredded Cheese

Freshly shredded cheese melts smoother and creates a better texture. Pre-shredded cheese can sometimes lead to a slightly oily or grainy finish.

Check for Doneness

The casserole is ready when the center is set, the edges are bubbling, and a knife inserted into the middle comes out mostly clean. If the top browns too quickly, loosely tent with foil and continue baking.

Let It Rest Before Slicing

Allow the casserole to rest for at least 15 minutes after baking. This helps it firm up and makes slicing much cleaner and easier.

Finish for Best Flavor

Add a light squeeze of fresh lime juice and a sprinkle of cilantro just before serving. This brightens the dish and balances the richness.
