Step-by-step instructions

Frequently asked questions (FAQ's)
Ground turkey is slightly leaner and lower in calories and fat than ground beef, making it a healthier option. However, ground beef does contain more flavor.
Penne, ziti, rotini, cavatappi, or rigatoni all hold the sauce well and bake beautifully.
Spinach, mushrooms, zucchini, broccoli, bell peppers, peas, and carrots are all great additions.
This dish can be made up to two days in advance. Keep the casserole covered tightly with plastic wrap or foil in the refrigerator until you are ready to bake it.

Top Tip
Cook the pasta just until al dente. Since the casserole continues cooking in the oven, slightly firm pasta will finish baking without becoming soft or mushy. It's a simple step that makes a big difference in the finished dish.
