The answer, and the disagreement underneath it
What searing actually buys you
One settled fact, one belief our own reviews still carry,
and what our own numbers do and don't back up.
Settled, not new

It browns the crust. It does not seal anything in
Searing browns the surface for flavor and fond, but it does not seal in juices -- that's folklore; searing is a flavor lever, not a moisture lever, so it's genuinely optional.
A dry surface above roughly 140°C browns: amino
acids in the beef react with its own sugars and build roast flavour a
braising liquid never develops on its own. Nothing in a lidded pot
gets past a simmer, so that reaction can only happen before the
liquid goes in, and the flavour compounds it makes dissolve straight
into the sauce. Cooks who reported searing for a deeper colour and a
more savoury gravy are describing a real, uncontested effect.

What to do: sear hard on every side if you want
that flavour in the sauce. It costs a pan and ten minutes, nothing
else.
A belief our own reviews still carry

“It also makes it more tender and moister”
Sear/brown the meat thoroughly before braising for a more tender, moister roast.
This is the exact claim the literature already
overturned for a steak, showing up again in home-cook write-ups of a
braise. Nobody in these reviews argued the other side of it, so it is
not a contested claim inside our data, just an untested one. It is
also, on the numbers below, not one we can back up.
What to do: treat this as a belief worth
knowing about, not a reason on its own to sear.
What our own numbers show
49 seared vs 26 not
On tenderness, the two groups come out tied
Searing is the only cooking choice in this dish with zero fitted effect behind it: 11 cooks described changing it, too few to estimate an outcome from. Comparing the two groups directly on tenderness, the recipes that sear and the recipes that skip it land closer together than the smallest real, fitted difference anywhere else in this dish. We hold no score at all for moistness or juiciness on any recipe here,
seared or not: that word pair exists in how we describe outcomes, but
nothing was ever fitted to it. Tenderness is the closest proxy we
have, and it does not move with searing.
What to do: if a recipe skips the sear, don't
expect a drier roast because of it. Twenty-six of the recipes here
do exactly that.
