How It Works

How Marinade Amounts Are Calculated

Formula

Total Marinade = Meat Weight (lbs) x Coverage Factor

The standard ratio is about 1/2 cup of marinade per pound of meat.

Classic Marinade Ratio

  • 50% oil: Carries flavor, helps browning
  • 25% acid: Tenderizes surface, adds tang (vinegar, citrus juice, wine)
  • 25% seasoning: Garlic, herbs, spices, soy sauce, etc.

    • Marinating Times

  • Fish/seafood: 15-30 minutes
  • Chicken/pork: 2-12 hours
  • Beef/lamb: 4-24 hours
  • Vegetables: 30 min-2 hours

    • Worked Example

    Marinade for 2 lbs of chicken thighs, standard coverage.

    meat_lbs = 2marinade_style = 0.5
    1. 01Total marinade = 2 x 0.5 = 1 cup.
    2. 02Acid (vinegar/citrus) = 1 x 0.25 = 0.25 cups (4 tbsp).
    3. 03Oil = 1 x 0.50 = 0.50 cups (8 tbsp).
    4. 04Seasoning = 1 x 0.25 = 0.25 cups (4 tbsp).

    Frequently Asked Questions

    Can you marinate too long?

    Yes. Acid-based marinades can break down the surface of meat, making it mushy. Fish should never marinate more than 30 minutes in citrus. Chicken can go 12 hours max, beef up to 24 hours.

    Should I marinate in the fridge?

    Always. Marinating at room temperature promotes bacterial growth. Keep marinating meat at 40°F or below. Use a zip-lock bag to maximize contact with minimal marinade.

    Can I reuse marinade?

    Never reuse marinade that has touched raw meat unless you boil it for at least 5 minutes first. It is safer and easier to reserve a portion before adding raw meat.
