Ingredients You Will Need to Make the Southwestern Casserole

Before getting started, make a trip to the grocery store to buy the following ingredients:

  • Rotini. Boil the rotini as directed on the box and then drain the pasta of any water.
  • Lean Ground Beef. Use at least 4.5 pounds of ground beef. Try cooking a big batch of ground beef and making a few of these ground beef recipes to stock your freezer.
  • Onions. Dice your onions into bits and pieces.
  • Taco Seasoning. Grab your favorite taco seasoning to use on your ground beef. More taco-style meals here!
  • Kidney Beans. Rinse and drain the kidney beans before adding them.
  • Monterey Jack Cheese. Be sure to sprinkle plenty of Monterey jack cheese over the casserole.

You should also have tomato paste, water, diced tomatoes, and chopped green chiles when assembling the Big Family Freezer-Friendly Southwestern Casserole.

Do I Have to Use Rotini Pasta?

Rotini pasta is a great addition to this casserole. However, if you want to use what you have, you can replace it with other types of pasta. Macaroni, rotelle, and bowties are just a few types of pasta that you can use when preparing the Southwestern Casserole.

Kidney Bean Alternatives

If you do not have kidney beans or would rather not use them, you can always use red beans or black beans as an alternative. These alternative beans will provide the same texture as kidney beans while contributing to the flavor of the dish. I often use whatever type of beans I have on hand to save money.

Can I Use Canned Green Chiles?

If you would like to avoid buying chiles and chopping them into pieces yourself, you can buy diced green chiles at the grocery store. Several discount stores offer these canned chiles. Buying pre-diced chiles is a great way to save yourself some time while still adding the flavorful ingredient to your casserole.

What to Side and Dessert Should I Make with the Southwestern Casserole?

Serve the Southwestern Casserole freezer meal with a spring salad and homemade bread with garlic. You can purchase frozen garlic bread or prepare your own bread at home using this French bread recipe, butter, minced garlic, and parsley flakes.

You can also add a side of vegetables like Sheet Pan Roasted BroccoliCollard Greens with Ham, or Garlicky Green Beans and Tomatoes.

In addition, you can add a delicious dessert to stretch the dinner. Try adding one of my many make-ahead cookie recipes, Baked ApplesStrawberry Trifle, or Banana Heath Pudding.

How to Freeze the Southwestern Casserole

You know how much I enjoy filling my freezer. You can freeze this meal too! After assembling all your Southwestern Casserole ingredients into a large baking dish, cover it with aluminum foil, and place the casserole in the freezer. You can leave it stored in your freezer for up to three months.

Always thaw the casserole overnight in your fridge before following the baking directions included in this recipe. Because you can freeze the Southwestern Casserole, you might want to make it when you have extra time and hold onto it until you need a good home cooked meal on a busy night.
