Is Stouffer's Baked Chicken Breast low FODMAP?

No — onion and garlic run all through the gravy on this tray, and you eat the whole thing in one sitting. The chicken breast itself is harmless, but the mashed potatoes are whipped with cream, skim milk, sour cream, and butter — several lactose sources layered together — and the 2%-or-less list adds onions, dried garlic, and onion powder, the concentrated fructan forms that matter even in small amounts. Bleached wheat flour appears too, though only as a minor gravy thickener, so the wheat contribution is trivial next to the alliums. Because the 8.875-oz tray is a single pre-mixed serving, there is no practical way to eat around the sauce: the gravy blankets the chicken and the dairy is beaten into the potatoes. If onion and garlic are your reliable triggers, skip this one rather than trying to portion it. If lactose is your only concern, the picture is a little friendlier, but the fructans are still there either way. A plain baked chicken breast with your own mash gets you the same comfort plate without the ambush.

📏 The full 8.875-oz tray is one pre-mixed serving — the gravy and dairy-whipped potatoes can't be portioned around, so the whole onion-garlic-lactose dose arrives at once.
