Ingredients

Making the Roast

  • pound boneless beef shoulder roast, cut into 2 inch chunks
  • 2 jalapenos, stems and seeds removed, diced
  • 1 yellow onion, diced
  • 1 teaspoon Slap Ya Mama seasoning
  • 1 teaspoon garlic powder
  • 1 teaspoon black pepper
  • 1 teaspoon paprika
  • 16 ounce Herdez Mild Salsa Verde
  • 30 corn tortillas
  • 8 ounce sour cream
  • 3 cups Monterey Jack cheese, shredded
  • 3 cups sharp cheddar cheese or spicy cheese, shredded

Poblano Cream Sauce

  • 3 roasted poblanos, seeds removed, roasted, peeled
  • 2 roasted jalapenos, seeds removed
  • 1 medium onion, sliced into rings
  • 15 ounce green enchilada sauce
  • 1 cup heavy cream
  • ¼ cup chicken broth
  • 1 teaspoon chicken bouillon
  • ½ teaspoon red pepper flakes

Instructions

Slow Cook the Roast

  • Spray a 6-8 quart crock pot with non-stick cooking spray, and add the beef, jalapenos, onions, seasonings, and salsa verde. Stir, cover, and cook on high for 4-5 hours or on low 7-8 hours.
  • Once the beef is fall-off-the-fork tender, place it on a plate and shred. Place back into the crock pot.

Or Cook Roast on Stove

  • Melt a tablespoon of butter over medium heat. Add all roast ingredients, stir to combine.
  • Cover and reduce heat to low and simmer for 2- 2 ½ hours over low heat, stirring occasionally
  • Shred and return to the pan.

Poblano Cream Sauce

  • Wash and dry the peppers.
  • Rub the peppers and onions with olive oil and place on the hot grill, or you can roast peppers over a medium flame on the stove using tongs.
  • Let poblano peppers cook until blistered and charred on each side, and grill the jalapeños and onions for a few minutes until the jalapeños and onions have softened a bit.
  • Remove from the grill and place the poblanos in a gallon size baggie, or a bowl, and cover with plastic wrap. Let steam for 10 minutes.
  • Remove from the baggie/bowl and peel the skin off each pepper.
  • Cut stems off of the poblano and jalapeno peppers, remove seeds, and place into a Vitamix or a blender.
  • Add grilled onions, enchilada sauce, heavy cream, chicken broth, chicken bouillon, and red pepper flakes into the Vitamix or blender and blend until creamy.

Assemble the Casserole

  • Heat tortillas in a pan over medium heat.
  • Preheat the oven to 375 degrees.
  • Spray a 9x13 deep baking dish with non-stick cooking spray.
  • Pour 1 cup of creamy poblano sauce into the bottom of the baking dish and top with a layer of corn tortillas.
  • Spread a thin layer of sour cream over tortillas.
  • Next, add shredded beef in an even layer on top of sour cream and then top with cheese and some poblano sauce.
  • Repeat layers ending with shredded cheese and poblano sauce.
  • Cover with aluminum oil and bake in the oven for 25 minutes.
  • Remove foil and bake for an additional 10 minutes or until the cheese has melted throughout.

Notes

  • Refrigerate the onions for about 30 minutes before slicing them to avoid stinging eyes.
  • Wash your hands and NEVER touch your face when handling hot peppers.
  • Look for a beef shoulder roast with plenty of marbling. That's what gets it nice and tender while it cooks.
  • Spray your baking dish just before layering the ingredients so the aerosolized oil doesn't pool at the bottom of the dish.
