Heat the oven to 350°F and spray a 2-quart casserole dish with cooking spray.
Cook pasta to al denté (per package directions), drain, and rinse with cool water. Lay the shells, open-side down, on a paper towel to dry while preparing the other ingredients.
12 uncooked jumbo pasta shells
Heat a large skillet over medium heat. Add the oil, onion, and diced jalapeño. Cook the onion and jalapeño, stirring occasionally, until translucent and fragrant, about 4-5 minutes. Transfer the cooked vegetables to a paper towel.
1 tbsp canola or vegetable oil, 1 medium onion, 1 jalapeño pepper
Add the ground beef to the skillet and cook, breaking the beef apart, until lightly browned. If there is just a small amount of rendered fat in the pan, no need to drain.
1 lb. lean ground beef
Add taco seasoning, cream cheese, salt, black pepper, 1 tbsp cilantro, ¼ cup taco sauce, and ½ cup shredded cheese to the beef mixture and stir well.
2 tsp taco or chili seasoning, 4 oz. cream cheese, 1 tsp kosher salt, ½ tsp freshly ground black pepper, 1 cup taco sauce, 1½ cups shredded Mexican blend cheese or Colby Jack, 3 tbsp chopped fresh cilantro
Cook 2-3 minutes, over medium-low heat, until mixture is hot and cheese has melted. Remove from heat.
Pour ¼ cup taco sauce into the prepared casserole dish.
Fill each pasta shell with 2 tbsp beef/cheese mixture and place the shells into the prepared dish on top of the sauce.
Pour the remaining ½ cup taco sauce around and in-between the shells.
Cover and bake 20 minutes.
Remove the dish from the oven, uncover, and sprinkle with crushed corn chips. Sprinkle the remaining cheese on top and bake about 10-15 minutes or until the cheese melts.
1 cup crushed corn chips
Garnish with sour cream, cilantro, and sliced green onions. Enjoy!
