  • Thyme or rosemary for added aroma.
  • A tablespoon of Dijon mustard in the cream for a tangy twist.

Vegetarian Suggestions:

Ensure the cheese used is vegetarian, as some cheeses contain animal rennet.

Potato Gratin Recipe – Vegan Version

To transform Potato Gratin into a delicious vegan meal, you would just need to substitute a few key ingredients with their plant-based counterparts. Here’s how you can make it vegan:

  1. Potatoes: No change needed, as potatoes are naturally vegan.
  2. Heavy Cream: Use a full-fat canned coconut milk or any rich dairy-free cream alternative designed for cooking. There are also vegan cream substitutes made from soy, cashew, or almonds available in the market.
  3. Milk: Opt for unsweetened almond milk, soy milk, oat milk, or any other plant-based milk you prefer. These will work well for the base of your gratin.
  4. Garlic: No change needed, continue to use fresh garlic for flavoring.
  5. Butter: Use a vegan butter substitute or a mild-flavored oil like avocado or olive oil for greasing the dish.
  6. Grated Cheese: There are many vegan cheeses available, made from nuts like cashews or almonds, soy, or tapioca. Look for a vegan cheese that melts well to get that signature gratin texture.
  7. Salt, Pepper, Nutmeg: No change needed, as these are all vegan-friendly.

When preparing vegan Potato Gratin, keep in mind that plant-based milk and cream alternatives might have different fat content and may behave differently when heated. You may need to adjust quantities or cooking times slightly.

Taste and adjust your seasoning as necessary, since vegan cheeses can have different levels of saltiness than their dairy counterparts.

With these substitutions, you’ll still achieve a creamy, satisfying dish, but it will be entirely plant-based.

Enjoy your vegan Potato Gratin!
