What to serve it with

This casserole is fantastic on its own but can be paired with crispy tortilla chips for crunch. A bright, fresh side salad adds a refreshing contrast to the richness of the dish. You might also enjoy serving it with some avocado slices or a dollop of sour cream for added creaminess. For an extra kick, consider adding diced jalapeños or hot sauce.

Storage and reheating

Leftovers can be stored in the refrigerator for up to three days. Ensure they are in an airtight container to maintain freshness. For longer storage, you can freeze the casserole for up to three months. Just make sure to let it cool completely before transferring it to the freezer. When reheating, aim for an internal temperature of 165°F for food safety, and remember the two-hour rule for room temperature foods.

Tips for best results

  • Use lean ground turkey to cut down on fat while still enjoying a flavorful dish.
  • To save time, chop your onions and peppers in advance.
  • Consider adding other veggies, such as zucchini or spinach, to increase nutrition.
  • If you prefer a spicier kick, add some diced green chilies or extra taco seasoning.
  • Be sure to let the casserole sit for a few minutes after removing it from the oven to help it set before serving.

Ways to change it up

There are many ways to customize this casserole to suit your preferences. Swap out black beans for pinto or kidney beans. You can also experiment with different types of cheese, such as Monterey Jack or pepper jack for a bit of spiciness. If you’re looking for a gluten-free option, serve the casserole with quinoa instead of tortilla chips.

Can I use ground beef instead of turkey?

Yes, ground beef can be substituted for ground turkey if you prefer. Just ensure it is cooked to an internal temperature of 160°F.

How long do leftovers last in the refrigerator?

Leftovers can stay fresh in your refrigerator for up to three days when stored properly.

Can I make this casserole ahead of time?

Absolutely! You can prepare the casserole ahead of time and store it in the refrigerator or even freeze it for later use. Just remember to modify cooking times if it has been refrigerated or frozen.

What other toppings work well?

Besides cheese, you can try toppings such as fresh cilantro, diced avocados, or sliced jalapeños for extra flavor.

Is this recipe gluten-free?

The recipe is naturally gluten-free, but be sure to check the taco seasoning packet for any gluten-containing ingredients.
