What You’ll Need

Ingredients for Paleo Chicken Casserole: carrots, yellow squash, zucchini, bell pepper, eggplant, onion, tomatoes, Italian spices, olive oil, garlic, chicken thighs, salt, and black pepper.

Ingredient Notes

  • Chicken thighs: Use bone-in, skin-on thighs for maximum flavor and juiciness. Look for chicken raised without antibiotics or hormones.
  • Vegetables: This recipe uses eggplant, garlic, carrots, bell pepper, onion, yellow squash, zucchini, and tomatoes. Feel free to use any variety of these vegetables.
  • Seasonings: Salt, black pepper, and Italian spices are used to create a fresh, savory, and earthy flavor combination that enhances the chicken and vegetables.

Add-ins and Substitutions

  • Substitute other vegetables: You can use broccoli, cauliflower, butternut squash, spinach, spaghetti squash, or any other vegetables you prefer.
  • Add bacon: For an extra savory flavor, you can add crispy bacon. Cook it first and chop it up to add to the casserole.
  • Use a different cut of chicken: If you prefer, you can use boneless chicken thighs, chicken breasts, drumsticks, or even shredded chicken. Just adjust the cooking time, as boneless cuts cook faster.
  • Add coconut milk: To make the casserole creamier, you can add coconut milk to create a savory and rich sauce for the chicken and vegetables.

How to Make Paleo Chicken Casserole

  • Brown the chicken: Season the chicken and brown both sides in a skillet with olive oil.
  • Transfer chicken to a baking dish: Place the chicken thighs in a 9×13-inch deep baking dish and spread minced garlic over the top.
  • Sauté the vegetables: In the same skillet, sauté the onion and carrots, followed by the bell pepper. Add the eggplant and sauté briefly.
  • Add the rest of the veggies and spices: Add the yellow squash and zucchini, then mix in the tomatoes and garlic just enough to combine. Avoid overcooking the tomatoes.
  • Combine and bake: Add the sautéed vegetables to the baking dish with the chicken. Cover with foil and bake at 370 degrees Fahrenheit for 1 hour. Serve warm.

Pro Tip: Use the heat of the skillet to warm the tomatoes without actually cooking them to preserve their texture.

Recipe Tips

  • Top the chicken with minced garlic: Adding fresh minced garlic on top of the chicken enhances its flavor.
  • Add the vegetables one at a time: Add each vegetable to the skillet one at a time to extract maximum flavor and prevent them from becoming mushy.
  • Cook the zucchini and yellow squash near the end: These vegetables can become mushy easily, so sauté them towards the end to retain their texture.
  • Cover the baking dish with foil: This helps to retain moisture and ensure even cooking, resulting in tender and flavorful chicken and vegetables.
