Ingredients
- 4 cups diced or shredded cooked chicken breast

- 3 cloves garlic, minced
- 1 cup ranch dressing

- 1 cup shredded cheddar cheese (divided)
- 5 cups broccoli florets
- 1 pound thawed frozen spinach, well-drained
Instructions
- Step 1: Preheat the oven to 375°F (191°C). If using frozen spinach, thaw completely and squeeze out excess water. For fresh broccoli, boil for 1–2 minutes until bright green, then drain well.
- Step 2: In a large bowl, combine the chicken, chopped bacon, prepared vegetables, minced garlic, ranch dressing, and half of both the mozzarella and cheddar cheeses. Mix everything thoroughly. You can also mix all ingredients directly in the casserole dish to save on cleanup.
- Step 3: Transfer the mixture to a 9×13 inch (23×33 cm) casserole dish and spread evenly.
- Step 4: Sprinkle the remaining mozzarella and cheddar cheeses evenly over the top of the casserole.
- Step 5: Bake for about 15 minutes, or until the top is hot and bubbly. Remove from the oven, let it cool slightly, then serve warm.
Tips & Variations
- For extra flavor, add a teaspoon of ranch seasoning or smoked paprika to the mixture before baking.
- Swap the chicken with turkey breast or cooked sausage for a different protein twist.
- Use fresh spinach instead of frozen; just sauté and drain it well before mixing.
- For a crispier topping, sprinkle some parmesan cheese over the shredded cheese before baking.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave or cover the casserole with foil and bake at 350°F (175°C) until heated through. Avoid overcooking to keep the chicken tender.
