How to Make Southwest Tuna Casserole

  1. Preheat oven to 350°F (175°C).
  2. Coat a 2-quart casserole dish with non-stick cooking spray.
  3. Cook pasta according to package directions until al dente. Drain and set aside.
  4. While pasta cooks, heat canola oil in a large skillet over medium-high heat.
  5. Add chopped onion and celery; cook and stir until softened, about 3-5 minutes.
  6. Stir in frozen corn and cook for 2 more minutes.
  7. Add dairy-free mayonnaise, salsa, and chili powder to the skillet. Stir until well combined.
  8. If the mixture is too thick, add non-dairy milk or chicken stock, 1 tablespoon at a time, until desired consistency is reached.
  9. Gently stir in the drained tuna and cooked pasta.
  10. Pour the tuna mixture into the prepared casserole dish.
  11. Sprinkle evenly with dairy-free cheese.
  12. Bake for 25-30 minutes, or until bubbly and cheese is melted and slightly browned.
  13. Let cool slightly before serving. Enjoy!
