Creamy Chicken Spinach Enchilada Casserole Ingredients

For specific amounts, please refer to the printable recipe card at the bottom of the post.

• Boneless Skinless Chicken Breast – cooked and shredded (see tips below)
• Butter
• Fresh Mushrooms – sliced white or baby Bella’s
• Large Yellow Onion – diced
• Dash Of Nutmeg – a defining flavor in chicken and spinach enchiladas casserole
• Frozen Chopped Spinach – boxed and thawed spinach must be squeezed or drained.            
• Sour Cream – is the tangy, creamy base for the enchiladas’ white sauce. 
• Half & Half -Adds richness and increases the velvety smoothness of the white sauce.
• Chopped Green Chiles – sold at the grocery store in a small can in the international aisle, usually by the taco shells.
• Ground Cumin – A signature spice in enchilada recipes that introduces warm, aromatic, and earthy notes. 
• Salt & Cayenne Pepper – Both seasonings highlight and balance flavors with a touch of fiery zest.
• Flour Tortillas
• Cheese – Monterey Jack or Four Cheese Mexican Blend are my usual go-to for this casserole recipe.

QUICK TIP: if you forget to thaw your spinach ahead of time, and your microwave has a quick thaw setting (usually for 1 pound of ground beef) it works perfectly to quickly thaw the box of frozen spinach.

How To Make Easy Shredded Chicken In No Time:

Using a stand mixer with a paddle attachment is a quick and convenient way to get even consistency for easy shredded chicken recipes.

Simply place the cooked chicken in the bowl of the mixer, attach the paddle attachment, and mix on low speed for about a minute or until the chicken is shredded exactly the way you want it.

Paddle Mixer Shredded Chicken Tips:

• For quick and even shredding, use warm chicken.
• If the chicken is dry, add a splash of water or broth to help it shred. (Based on the recipe, try butter or olive oil.)
• A whisk attachment to shred chicken also works but may take a bit longer.

This method is much faster than shredding chicken by hand, producing evenly shredded chicken. Make a large batch, portion it into 1 or 2-cup servings and freeze. Takes all the prep work out of easy weeknight meals: tacos, salads, chicken enchiladas, and more.

Recipe Notes:

• You can cook the chicken in a crockpot and add water, olive oil, salt, pepper, garlic, and cumin. Crockpot chicken will be tender, moist, and easy to shred. 
• Use leftover chicken; alternatively, you can sauté, grill, or bake the chicken. Rotisserie chicken is quick, convenient, and economical.
• Place cooked chicken in the bowl of a stand mixer with the paddle attachment.  Turn the mixer on low for about 30-60 seconds, and you will have shredded chicken in 1 minute or less!
• Chopped frozen spinach should be broken up and drained well to avoid watering down the enchilada white sauce. Thaw in a colander over a bowl in the fridge, or squeeze in a cheesecloth.

Serving Suggestions

This family-friendly chicken dinner idea doubles as a make-ahead recipe, saving you from the chaos of busy evenings. Here are a few serving ideas for easy weeknight dinners if you want to add some extra touches!
