Savory Caramelized Onion Tart - Vegan recipe hero image

I remember the first time I made this Savory Caramelized Onion Tart; the aroma of onions cooking low and slow filled my kitchen, and I couldn't wait to share it with friends.

It's one of those recipes that brings everyone together, and it’s a great way to showcase the beauty of plant-based cooking.

Plus, caramelizing onions is so therapeutic—trust me, it's worth the wait!

What Makes This Recipe Special

  • ✓Made with simple, plant-based ingredients that are easy to find
  • ✓No animal products - completely vegan and cruelty-free
  • ✓Perfect for beginners and experienced cooks alike
  • ✓Delicious results that everyone will love, vegan or not

Ingredients & Substitutions

I love using a mix of yellow and red onions for a touch of sweetness and color. If you don’t have vegan vegan butter, coconut oil works beautifully too! Just remember to keep it cold when making the crust.

Tips & Notes

  • •If you're short on time, feel free to use store-bought vegan pie crust; it saves a lot of time!
  • •I like to sprinkle a bit of extra thyme on top right before serving for an aromatic touch.

Recipe Variations

  • •Sometimes I'll add sautéed mushrooms to the onions for an earthy flavor boost.
  • •You could also throw in some spinach or kale for a pop of color and nutrition.

Storage & Freezing

This tart keeps well in the fridge for about 3 days. Just cover it with some foil or plastic wrap, and it’ll be ready for a quick snack or a light lunch!

Frequently Asked Questions

Can I use a different type of flour?

Absolutely! Whole wheat flour can work, but it may give a denser texture. Just adjust the liquid a bit if needed.

How do I store leftovers?

I usually keep mine in an airtight container in the fridge for up to 3 days. Reheat gently in the oven for the best texture!

Ingredients

Instructions

  1. 1

    In a large bowl, combine the flour and a pinch of salt. Cut in the vegan vegan butter with a pastry cutter or your fingertips until the mixture resembles coarse crumbs.

  2. 2

    Add in the ice water, one tablespoon at a time, mixing until the dough comes together. Form it into a disc, wrap in plastic, and chill in the fridge for about 30 minutes.

  3. 3

    While the dough chills, heat the olive oil in a large skillet over medium-low heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until the onions are golden brown and caramelized, about 30-35 minutes.

  4. 4

    Once the onions are caramelized, stir in the balsamic vinegar and fresh thyme. Cook for another minute and then remove from heat.

  5. 5

    Preheat your oven to 375°F (190°C). Roll out the chilled dough on a lightly floured surface to fit a 9-inch tart pan. Press the dough into the pan and trim any excess.

  6. 6

    In a bowl, mix the nutritional yeast, plant-based oat milk, salt, and pepper until smooth. Spread the caramelized onions evenly over the crust, then drizzle the nutritional yeast mixture on top.

  7. 7

    Bake in the preheated oven for 25-30 minutes, or until the edges are golden and the tart is set. Let it cool slightly before slicing.

  8. 8

    Serve warm or at room temperature, and enjoy the savory goodness with your loved ones!
