Ingredients
  

  • 2 cups (8 ounces) uncooked elbow macaroni
  • 2 pounds ground beef
  • 1 large onion, chopped
  • 2 garlic cloves, minced
  • 2 cans (14-1/2 ounces each) diced tomatoes, undrained
  • 1 can (16 ounces) kidney beans, rinsed and drained
  • 1 can (6 ounces) tomato paste
  • 1 can (4 ounces) chopped green chiles, drained
  • 1-1/2 teaspoons salt
  • 1 teaspoon chili powder
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon pepper
  • 2 cups shredded Monterey Jack cheese
  • 2 jalapeno peppers, sliced

Instructions
 

  • Cook the macaroni according to the package directions. Drain and set aside.
  • In a large saucepan, cook the ground beef and chopped onion over medium heat until the meat is fully browned, breaking it into crumbles as it cooks. This should take about 6-8 minutes.
  • Add the minced garlic and sauté for an additional minute to release its aroma.
  • Drain any excess fat from the meat mixture.
  • Mix in the diced tomatoes, kidney beans, tomato paste, green chiles, salt, chili powder, cumin, and pepper. Stir well to combine.
  • Bring the mixture to a boil, then reduce the heat and simmer uncovered for 10 minutes to let the flavors meld.
  • Preheat your oven to 375°F (190°C).
  • Incorporate the cooked macaroni into the beef mixture, stirring until evenly coated.
  • Transfer the mixture into two greased 2-quart baking dishes.
  • Sprinkle Monterey Jack cheese evenly over the top of each casserole and layer the jalapeno slices on top.
  • Cover the dishes with foil and bake for 30 minutes.
  • Uncover and bake for an additional 10 minutes, until the cheese is bubbly and golden.
  • Enjoy one casserole fresh, and let the second cool completely before covering it tightly and freezing for up to 3 months.
