Ingredients

Scale
  • 8 ounces pasta (penne, rotini, or shells)

  • 2 tablespoons olive oil

  • 1 medium onion, diced

  • 3 cloves garlic, minced

  • 1 red bell pepper, diced

  • 1 yellow bell pepper, diced

  • 1 green bell pepper, diced

  • 2 cups cooked prime rib, thinly sliced

  • 1 cup cherry tomatoes, halved

  • 1 teaspoon chili powder

  • 1 teaspoon smoked paprika

  • ½ teaspoon cumin

  • ½ teaspoon black pepper

  • ½ teaspoon salt (adjust to taste)

  • 1 cup heavy cream

  • 1 cup shredded sharp cheddar cheese

  • ½ cup shredded Monterey Jack cheese

  • ¼ cup chopped fresh cilantro

  • 2 green onions, sliced (optional for garnish)


Instructions

  • Bring a large pot of salted water to a boil. Cook pasta according to package instructions until al dente. Drain and set aside.

  • Heat olive oil in a large skillet over medium heat. Add diced onion and cook until translucent, about 3–4 minutes. Stir in minced garlic and cook for another 30 seconds until fragrant.

  • Add the diced red, yellow, and green bell peppers. Sauté until slightly tender but still crisp, about 4–5 minutes.

  • Stir in the thinly sliced prime rib and cook for 2–3 minutes, just until heated through.

  • Sprinkle chili powder, smoked paprika, cumin, salt, and black pepper over the meat and vegetables. Stir well to combine and let spices bloom for a minute.

  • Add cherry tomatoes and heavy cream. Reduce heat to low and simmer for 3–4 minutes until slightly thickened.

  • Gradually stir in cheddar and Monterey Jack cheese until melted and the sauce is creamy.

  • Add the cooked pasta to the skillet, tossing to coat evenly with the sauce.

  • Garnish with chopped cilantro and green onions, if desired. Serve immediately.

Notes

  • Use tender leftover prime rib for the best texture and flavor.

  • Adjust chili powder for milder or spicier heat.

  • Substitute or add vegetables such as zucchini, corn, or black beans for variety.

  • Cheese options can be customized; pepper jack adds extra Southwest flavor.

  • Can be prepared a day ahead and reheated gently on the stove.
