The large pectoral muscle of the bird - very lean, mild, and quick-cooking, with almost no connective tissue to break down.
What it does in a recipe: Lean, neutral protein that cooks fast and carries whatever seasoning it is given. Pick the swap that covers that job - the ratios below are written so you can act on them without doing any arithmetic.
Also called: Boneless skinless chicken breast, Chicken fillet
Thigh is the same bird and the same flavour family, but the higher fat and collagen content mean it stays moist well past the point where breast has gone dry.
MethodGive it a few extra minutes - thigh is at its best around 175°F rather than the 165°F you would stop breast at, because the collagen needs time to soften.
Trade-offDarker meat, richer flavour and a slightly looser grain. In a pale dish like a cream sauce the colour difference shows.
1 lb chicken breast = 1 lb extra-firm tofu, pressed and sliced into slabs
Pressed extra-firm tofu holds a slab shape and browns on a hot surface, giving you the same knife-and-fork component even though the protein network is entirely different.
MethodPress hard, then marinate - unlike chicken, tofu absorbs almost nothing during cooking, so all the seasoning has to go in beforehand.
Trade-offNo fibrous grain at all, and it will not shred or pull. Expect a soft interior even when the outside is well browned.
Allergen checkSoy-based, so it is unsuitable for anyone with a soy allergy. Read the label on flavoured or baked tofu in particular, and take a diagnosed soy allergy as a matter for a clinician rather than a recipe note.
Worth knowing
Breast is lean enough that the difference between perfect and dry is about two minutes. Pull it at 165°F and rest it rather than cooking to a visual cue.

Chicken breast in summary
Chicken breast at a glance: category, its job in a recipe, the diets it suits, the diets its substitutes can satisfy, and how many substitutes there are.
Can I use chicken thigh (boneless, skinless) instead of chicken breast?
1 lb chicken breast = 1 lb boneless skinless chicken thigh. Thigh is the same bird and the same flavour family, but the higher fat and collagen content mean it stays moist well past the point where breast has gone dry. Darker meat, richer flavour and a slightly looser grain. In a pale dish like a cream sauce the colour difference shows.
Can I use turkey breast instead of chicken breast?
1 lb chicken breast = 1 lb turkey breast, sliced or cut to the same thickness. Turkey breast is structurally near-identical lean white muscle, so it cooks on the same timings as long as the pieces are cut to a matching thickness. Slightly firmer bite and a marginally stronger flavour, and it goes dry even faster than chicken breast does.
Can I use pork loin instead of chicken breast?
1 lb chicken breast = 1 lb pork loin, cut to the same size. Pork loin is the pig's equivalent lean muscle and behaves the same way under heat - fast-cooking, mild, and unforgiving of overcooking. Sweeter and denser than chicken. It suits fruit, mustard and caraway more naturally than lemon-and-herb treatments.
Can I use extra-firm tofu instead of chicken breast?
1 lb chicken breast = 1 lb extra-firm tofu, pressed and sliced into slabs. Pressed extra-firm tofu holds a slab shape and browns on a hot surface, giving you the same knife-and-fork component even though the protein network is entirely different. No fibrous grain at all, and it will not shred or pull. Expect a soft interior even when the outside is well browned.
Cooking around an allergy? Diet tags here describe the ingredient itself, not any particular brand. Processed products change formulation without notice and shared production lines are common, so read the label on everything you use. A severe allergy is a medical matter - confirm with the manufacturer or your clinician rather than relying on a substitution chart.
