One‑Pan Chicken Enchilada Casserole

In my ongoing challenge to cook my way through the freezer, I came across a package of Bell & Evans chicken breast cubes—an ideal starting point for this comforting One-Pan Chicken Enchilada Casserole. This recipe delivers All the creamy, cheesy comfort of classic enchiladas—without the fuss of rolling each one.

The Inspiration

This recipe was inspired by Mary Younkin’s Creamy Green Chile, Chicken and Spinach Enchiladas from The Weeknight Dinner Cookbook (Page Street Publishing, 2016). I originally made a vegetarian version of this dish for my daughter and her family, who don’t eat meat or chicken. I increased the amount of black beans and added corn. Next I added sautéed onions and red pepper. It quickly became one of their favorite recipes, and now I make both versions depending on who’s coming to dinner.

Friends and family love to tease me about never following a recipe exactly as written, even the first time I make it. After more than 40 years of cooking, I know what I like—and I’m not afraid to substitute when the pantry is missing an ingredient or two. The downside? Sometimes I hand someone the original recipe instead of my tweaked version, and they’re baffled when their dish doesn’t taste like mine. Mea culpa. As a consequence, I’m making a real effort to jot down my changes as I cook so I can actually recreate the dish the next time.

But I digress—back to the casserole.

A New Technique

I was concerned the chicken would become dry during the bake in the oven. So for this batch, I used a technique called velveting the chicken, a method commonly used in stir‑fries to keep the meat tender and moist. The chicken is tossed with water and left to absorb it for 5–10 minutes. Then cornstarch and a bit of oil are added, and the mixture marinates for 15–20 minutes. After that, the chicken is ready to be quickly seared before going into the casserole. If you’re curious about the technique, you can read more here: https://thewoksoflife.com/how-to-velvet-chicken-stir-fry/. For a stir fry some soy sauce is added to the chicken along with the water.
