It’s my healthier take on the classic John Wayne casserole, and the great thing about this casserole, it’s surprisingly easy to make. We all need weeknight dinners that don’t take a lot of effort.
What is Johnn Wayne Casserole?
John Wayne Casserole is a hearty Tex-Mex dish inspired by the famous Hollywood star John Wayne. The casserole is a savory dish often popular among meat lovers and people who enjoy the flavors of the Southwest.
The classic dish typically consists of a base made with biscuits, ground beef, green chilies, sour cream, cheese, eggs, and various vegetables baked together in a casserole dish.
A Lighter Twist on a Classic Casserole
For this version of John Wayne casserole, I skipped the biscuit layer and added spinach to boost nutrition and keep it lighter. The egg-based topping bakes up with a soft, soufflé-like texture, giving this dish a healthier twist and still keeping all the bold, comforting flavors you expect from the original.
Here’s How I Make This Casserole
Brown the ground beef in a cast iron skillet for quick, even browning.
Add the seasoning (chili powder, cumin, oregano, garlic powder, and black pepper), black beans, and water.
Simmer for about 10 minutes to let the flavors come together.
Spread a creamy layer of sour cream, cheddar and Monterey Jack cheeses, and green chile peppers.
Make the final layer with egg yolks, cream or milk, steamed spinach, remaining cheese, and a spoonful of tapioca starch.
Whisk the egg whites until firm and gently fold them into the egg mixture for a light, fluffy topping.
Bake until bubbly and set.
How to steam spinach in the microwave?
Place spinach and 2 tablespoons of water in a microwaveable bowl and cover with a plate. Microwave until starting to wilt, about 1 – 2 minutes, depending on how much spinach you have. Squeeze excess liquid before using the spinach in a recipe.
