A Gluten-Free, Dairy-Free Chicken Casserole Remake of Classic King Ranch Chicken

I didn’t know about King Ranch Chicken until I moved to Texas. A friend used to bring leftovers to work, and the aroma — plus how much she enjoyed it — prompted me to create a dairy-free version. This casserole quickly became a comfort-food staple in our home and a hit with friends and neighbors.

Make This Dairy-Free Chicken Recipe: Step-by-Step

img 1570 4
  • Step 1: Poach the chicken in simmering water until cooked through (about 15–30 minutes, depending on thickness). Remove and shred.
  • While the chicken cooks, preheat oven to 375°F and complete the next steps.
  • Step 2: Chop the onion, jalapeño and garlic, then sauté in a large skillet over medium heat until softened.
  • Step 3: Add the Ro-Tel and spices, stir to combine, then set aside.
  • Step 4: Make the “cheese” sauce: warm the chicken broth and plant milk over medium-high heat, whisk in the corn starch until the mixture thickens. Reduce heat, stir in the dairy-free shreds and salt until melted, then remove from heat.

  • Step 5: Add shredded chicken to the skillet with the vegetables, then pour in the sauce and mix thoroughly.
  • Step 6: Spray a 9×13 baking dish with cooking oil. Arrange one layer of tortillas on the bottom and bake 4–5 minutes to slightly crisp them (tear tortillas in half as needed).
  • Steps 7–9: Layer half the chicken mixture over the first tortilla layer, add another layer of tortillas, then spread the remaining chicken mixture on top.
  • Step 10: Sprinkle 1 cup dairy-free cheese shreds over the casserole.
  • Step 11: Bake at 375°F for 20 minutes. Slice, garnish with lime, cilantro or avocado if desired, and serve.

FAQs

Can I use a rotisserie chicken?

Yes. Use about 4 cups shredded cooked chicken to replace the 2 pounds of boiled chicken breasts.

Can I use store-bought queso sauce?

Yes. Pre-made sauces are often thicker, so thin with a little plant milk if needed to reach your preferred consistency.

Can I meal prep this ahead of time?

Yes. Prepare the chicken, vegetables and sauce ahead and store in an airtight container in the fridge for 3–4 days. I recommend assembling and baking the casserole the day you plan to serve it for best texture.

Can I freeze this casserole?

Yes. Assemble and cool completely, then freeze in a freezer- and oven-safe dish. Thaw overnight in the fridge and reheat in the oven until warmed through.
