For extra crunch, sprinkle reserved crispy bacon on top after baking. Garnish with chopped green onions or chives if you like.
How to prepare the chicken
Using a store-bought rotisserie chicken is the quickest option—just shred and add. If you prefer to cook your own, you can bake, slow-cook, or use an Instant Pot to make shredded chicken.
- Bake chicken breasts in the oven and shred when cooked through.
- Slow-cook chicken with a little seasoning for tender shredding.
- Use an Instant Pot for fast, hands-off shredded chicken.
Shredded chicken is versatile and great to keep on hand for casseroles and other quick meals.
