snow peas substitute
in quiche.
Snow Peas adds crisp sweetness and bright color to Quiche. In the savory custard filling, the right substitute must hold its crunch during cooking.

adjustment for this dish
Snap peas swap 1:1 by volume but their thicker pods hold more water than snow peas. Blanch 2 minutes (vs 90 seconds), shock, and press 8 minutes under a plate — otherwise the rich custard slumps during the 45-minute bake and the golden wedge weeps when you slice it.

Zucchini

Slice thin on bias for similar flat shape

adjustment for this dish
Zucchini swap 1:1 by volume holds 95% water to snow peas' 88% and will wreck the custard set. Dice 1/4 inch, salt 2 tsp, rest 20 minutes, squeeze dry hard in a towel, then layer on the blind-baked crust before the pour — the filling still jiggles clean at the center.

Green Beans

Slice thin lengthwise for stir-fries
5.0
adjustment for this dish
Green beans swap 1:1 by volume but their skin resists the custard bond more than snow peas' thinner pod. Blanch 3 minutes, shock, dry, and cut 1/2-inch pieces so they sit evenly across the crust and the cream-and-egg filling sets around them without leaving raw pockets.

Celery
5.01 cup : 1 cup
Sliced on bias, keeps crunch in Asian dishes
5.0
adjustment for this dish
Celery swap 1:1 by volume keeps more crunch through the 45-minute bake than snow peas and brings a stronger aromatic. Peel the strings, dice 1/4 inch, sauté 3 minutes in butter to mellow the raw edge, then pat dry before the custard pour so the filling golds evenly across the wedge.
technique for quiche
technique
Raw snow peas in a quiche custard dump 40% of their weight as water during the 45-minute bake at 375°F, which turns the rich cream-and-egg filling into a weeping pond and leaves the crust soggy beneath the wedge. Blanch 3/4 cup sliced pods for 90 seconds, shock, then press between paper towels for 5 minutes under a plate — you want them below 10% residual moisture before they meet the custard.
Blind bake the crust with pie weights for 15 minutes at 400°F, brush with beaten egg, and return for 3 more so it seals against the pods' remaining moisture. Scatter the dried pods across the bottom of the crust, pour in the custard (4 eggs to 1 cup cream), and bake until the center jiggles like set yogurt but not liquid.
Unlike in omelet where pods meet eggs for 45 seconds, here they sit in a slow thermal bath for three-quarters of an hour, so any prep shortcut shows up as a slumped, pale filling when you slice the golden wedge.
pitfalls to avoid
watch out
Don't skip the blanch-and-press step — raw pods release 40% of their water into the custard during the 45-minute bake and slump the filling.
watch out
Avoid pouring hot custard over room-temperature pods; let them cool fully before the rich cream hits or you'll pre-cook pockets of egg.
watch out
Don't skip blind baking the crust for 15 minutes; without it the pod moisture soaks the bottom and you lose every golden wedge to sog.
watch out
Pull the quiche when the center jiggles like set yogurt, not when it's still liquid — pods hold residual heat and overcook the filling post-oven.
watch out
Don't pack pods to the edges of the crust; center-heavy placement keeps the slice structure intact when you cut a wedge.
