Overview
Asparagus turns mushy quickly if it’s overcooked, but it can stay stringy if it’s underdone. Sous vide keeps it bright green and crisp-tender, then you can finish with butter, lemon, or a quick char on the grill. This guide helps you choose texture targets for side dishes, salads, and meal prep.
Core Time & Temperature
| Doneness | Temperature | Time | Max Time |
|---|---|---|---|
| Crisp-Tender | 180°–183°F | 30 min | 1 h |
| Fully Tender | 183°–185°F | 45 min | 1 h |
Cooking time depends on thickness, not weight. Measure at the thickest part.
Food Safety Notes
Cooking time depends on thickness, not weight. Measure at the thickest part. Follow safe cooking practices and USDA guidelines for internal temperatures. Handle produce safely and keep bags below 183°F sealed tightly to avoid botulism risk. Chill leftovers quickly if not serving immediately.
