What makes this recipe healthy?

As a Registered Dietitian, I design my recipes to maximize nutrition without sacrificing satisfaction.

Here’s how I made this one with nutrition in mind:

• High protein from lean ground turkey and beans
• Contains dietary fiber from beans and corn
• Uses less cheese than other recipes (but it’s just as satisfying)
• More vegetables than other casseroles
• Lots of vitamins and minerals from nutritious ingredients

Key ingredients and swaps

Scroll down to the recipe card for the detailed recipe and ingredients list.

Lean ground turkey: Swap for lean ground chicken or beef, if preferred.

Zucchini: Zucchini is a great way to add extra fiber, volume, and micronutrients to this dish. I wouldn’t suggest any swaps.

White onion: Substitute yellow or red onion if needed.

Garlic: You can use fresh or jarred/pre-minced garlic in this recipe. You’ll need about a teaspoon of jarred garlic for every clove used in the recipe.

Canned green chilies: You can usually find these in the Mexican section of the grocery store. They’re sold in small cans.

Beans and corn: Use two cans of any beans you like, such as pinto beans, red kidney beans, white kidney beans, black beans, and/or corn. I used pinto and corn in this recipe, but use what you like.

Mini tortillas: Feel free to use corn or flour tortillas.

Red enchilada sauce: I suggest using store bought sauce in this recipe to make life easier.

Lime juice: I find a splash of lime juice really helps brighten store bought sauce. This is optional, but I do think it helps round out the flavors.

Shredded pepper jack cheese: If you can’t find exactly this, look for spicy monterey jack or cheddar. Any melty cheese with a little kick with work.

How to make turkey zucchini enchilada casserole

Position your oven rack to the middle and pre-heat to 375 F.

Back at your stove, heat a large pan to medium and add olive oil.

Add ground turkey. Use a spatula to crumble the turkey until it’s browned with minimal pink remaining. Stir occasionally as needed.

Add zucchini, onion, salt, pepper, and chili powder. Cook for 4-5 minutes, stirring occasionally, until onions are translucent and softened.

Add garlic and stir. Cook for 1-2 minutes or until just fragrant, stirring frequently to prevent burning. Turn off the heat.

Add chilies, beans, corn, enchilada sauce, lime juice (if using), and tortillas. Stir. If your pan isn’t big enough for all the ingredients, combine in a large bowl instead. Then, pour the mixture into your 9×13-inch baking dish and gently flatten with a spatula. Top with cheese.

Transfer to the oven and bake for 25-35 minutes or until cheese is bubbling. If desired, finish for 2-3 minutes under the broiler for extra browning, but watch it carefully to prevent burning. Let it rest for 10-minutes before serving.

Top tips

• Make sure your onions are soft in the pan before adding the next ingredients.
• Before adding your ingredients to the baking dish, taste the mixture and adjust lime juice or seasonings as desired. Every store bought enchilada sauce tastes a bit different, so it’s important to adjust to taste.
• Finish your casserole under the broiler for 1-2 minutes to brown the cheese.
