Main path: thick asparagus, 185°F for 10 to 12 minutes
Use this path intact when your cook matches Anova’s Butter-Poached Asparagus with Fresh Mint recipe: one bunch of thick, trimmed asparagus; butter, salt, and fresh mint; a 185°F (85°C) bath; and 10 to 12 minutes, with the recipe stating that time depends on thickness. Put asparagus in one single layer in a large zipper-lock or vacuum-seal bag. Anova lists water-immersion sealing or a vacuum sealer on its dry setting. When tender, plate it and serve it with the butter and mint from the bag. Anova: Sous Vide Butter-Poached Asparagus with Fresh Mint
Practical limit: “thick” is recipe wording, not a measured category supplied by this guide. Keep the stated one-layer arrangement. The recipe does not provide a refrigerator-start adjustment, a maximum bag load, or permission to stack bags, so this guide does not add one.
Source-Path Decision Gate
Choose a complete named path. Do not use a familiar temperature to fill missing conditions from another recipe.
| What matches your cook? | Use this supported path | Do not transfer |
|---|---|---|
| Thick asparagus with butter, salt, fresh mint, one layer, and immediate service | Use Anova Butter-Poached Asparagus with Fresh Mint: 185°F (85°C), 10 to 12 minutes. | Do not replace its stated thickness-dependent timing with 14 minutes from another recipe. |
| Green asparagus with butter, salt, garlic, Parmesan, one layer or two bags if needed, and immediate service | Use Anova Garlic Parmesan Asparagus: 185°F (85°C), 14 minutes. | Do not treat this as timing evidence for a named “thick” category; that recipe does not state spear thickness. |
| Different spear description, crowded or stacked bags, different start condition, or substituted method | No source-matched time is supplied here. | Do not average 10 to 12 minutes and 14 minutes, or turn them into a 10-to-14-minute range. |
The garlic-Parmesan path is a separate Anova-hosted recipe. It calls for trimmed green asparagus with butter, salt, garlic, and Parmesan at 185°F (85°C) for 14 minutes; it specifies one single layer in a food-safe bag, or two bags if needed, and directs the cook to drizzle the cooking liquid over the finished dish. It does not state spear thickness or give a rule connecting its 14 minutes to the butter-poached recipe. Anova: Sous Vide Garlic Parmesan Asparagus
Why there is no thin-to-thick timing chart
Two recipes sharing 185°F do not make one validated schedule. They state different ingredients, asparagus descriptions, bag instructions, and times. Combining them would hide conditions a reader needs to reproduce either source.
Vegetable schedules remain ingredient- and recipe-specific. For another source-matched path, use the dedicated guides for sous vide corn on the cob or sous vide potatoes rather than carrying an asparagus time into a different vegetable.
USDA asparagus grades do not solve that gap. Its grade standards list minimum diameters of 1/2 inch for U.S. No. 1 and 5/16 inch for U.S. No. 2, unless otherwise specified. Those are commercial grade requirements, not culinary labels for thin, medium, or thick spears and not sous vide timing categories. Do not measure a spear against those minimums and assign it a cook time from this article. USDA AMS: Asparagus Grades and Standards
Wash, trim, bag, and serve within scope
Before trimming and bagging fresh asparagus, wash it thoroughly under running water. Use clean hands and keep it away from unclean surfaces and utensils. FDA does not recommend washing produce with soap, detergent, or commercial produce wash. Washing can reduce bacteria, but it does not eliminate bacteria; this is produce-handling guidance, not a safety guarantee. FDA: Selecting and Serving Produce Safely
Then follow one selected recipe’s ingredients, bag arrangement, and serving instruction together. This guide covers fresh asparagus for immediate service only. It does not supply guidance for storage, cook-chill, reheating, pasteurization, frozen or canned asparagus, soup, searing, or changes to start state and bag load.
When texture misses your target
If asparagus is not tender at the butter-poached recipe’s stated endpoint, or is softer than you want after either named recipe, do not turn that result into a general time adjustment. Record the named recipe, its stated spear description, the one-layer or two-bag arrangement, and the starting condition you used. For a next cook, choose a source-matched recipe rather than transferring or averaging times.
Bottom line
For thick asparagus matching Anova’s butter-poached recipe, 185°F (85°C) for 10 to 12 minutes is the supported immediate-service path. The 14-minute garlic-Parmesan recipe is a separate path, not an extension of that clock. If your conditions do not match either named recipe, this evidence does not supply a time.
