Ingredients

  • 1 unit Instant-read meat thermometer
  • 1 unit Refillable oil spray bottle
  • 1 pack Perforated parchment liners

Step-by-Step Instructions

  1. Step 1: Apply the 25/20 formula

    Take any oven recipe: subtract 25F (15C) from the temperature and multiply the time by 0.8 to get the air fryer time.

  2. Step 2: Preheat before adding food

    Run the air fryer empty for 3-4 minutes so proteins sear and the crust forms instantly.

  3. Step 3: Check early, verify with a thermometer

    Start checking at 75% of the converted time. Confirm internal temperatures before serving.

Ingredient Substitutions & Expert Guide

## The Oven to Air Fryer Conversion Cheat Sheet Every air fryer owner hits the same wall: "my recipe says oven 425F for 35 minutes - what do I do?" The answer is the chef-tested **25/20 rule**: lower the temperature by 25F (15C) and reduce the cooking time by 20%. ### The Formula | Oven Temp | Air Fryer Temp | Time Cut | | :--- | :--- | :--- | | 350F / 175C | 325F / 165C | minus 20% | | 375F / 190C | 350F / 180C | minus 20% | | 400F / 200C | 375F / 190C | minus 20% | | 425F / 220C | 400F / 200C | minus 20% | | 450F / 230C | 425F / 220C | minus 20% | ### The Golden Rules 1. **Always preheat 3-4 minutes** - hot air needs a running start. 2. **Never fill the basket over about 70%** - crowding blocks airflow and steams instead of crisps. 3. **Shake or flip halfway** - the fan does the work, your basket needs a turn. 4. **Verify with a thermometer** - chicken 165F, steak 130-145F, salmon 135F, pork 145F. --- ## How To Use This Chart Like A Pro The 25/20 rule converts most oven recipes, but the best cooks treat it as a starting line, not a finish line: start checking at 75% of the converted time and let the thermometer make the final call. ## When The Rule Needs Extra Care - **Batter-heavy dishes** (cake loaves, muffins): keep the lower temp, extend time a touch - batter needs time to set before the crust colors. - **Delicate fish**: drop 5F extra and check two minutes early; thin fillets finish fast. - **Frozen food**: add zero time - the air fryer defrosts and crisps in one motion. ## Tools That Make Conversion Foolproof A probe thermometer with a leave-in display, perforated parchment liners, and an oil mister. These three turn "guess cooking" into repeatable results. ## When To Ignore The Rule Filled or liquid dishes (soups, braised stews, saucy casseroles) do not belong in an air fryer - the fan dries the surface before the middle cooks. Reach for a Dutch oven for those. ## Quick Math Examples - Oven 375F / 20 min -> 350F / 16 min - Oven 425F / 40 min -> 400F / 32 min - Oven 350F / 12 min -> 325F / 10 min
