Smaller pieces distribute through the dish more evenly and keep every bite from feeling meat-heavy or uneven.
Heat a skillet over medium heat and add olive oil or butter.Fat helps restore moisture and revives roasted flavor that dulls in the refrigerator.
Cook aromatics first. Add onions, garlic, shallots, or scallions and cook until softened and fragrant. This rebuilds the flavor foundation before the chicken goes in.
Add a starch or base ingredient.
Stir in cooked rice, pasta, potatoes, beans, or vegetables. The leftover chicken should support the dish, not carry it alone.
Add the chicken last.Leftover chicken is already cooked. Heat it gently for just a few minutes so it stays tender instead of turning stringy and dry.
Add moisture if needed.A splash of stock, cream, soy sauce, salsa, or lemon juice helps wake up refrigerated flavors.
Taste before serving.
Leftovers almost always need a little extra salt, acid, or fresh herbs to taste alive again.
Notes
It actually took less time to make dinner tonight than to write & post this recipe. Isn't that a funny thought?
