Chef Petrina Peart’s Galette de Ratatouille

Discover the story
Chef Petrina Peart, Camila, and her Mother-in-Law got together (virtually) in the kitchen to cook this delicious Galette de Ratatouille! This dish is also known as Beet Greens Pesto, Beets, Courgettes, Tomato, and Red Onions in Pate Brisee crust.

We welcome Chef Petrina Pert as she shows us how to make her 100% vegan Galette de Ratatouille. She was part of a past chef series we had on WOT as you will see in the recipe video! Chef Petrina is Le Cordon Bleu trained and specializes in making incredible dishes that are plant-based.  This recipe she made with Camila is no exception!

Here are some tips from Chef Petrina when you make this dish: 

Tip for blending your Pesto:
When making the pesto in a blender or using an emersion blender, add the oil first in the blender to help the blender combine the ingredients better.

Tip to making flaky pie crust:

Add the water to the dough a little at a time until you get a flaky consistency.

Tip for seasoning with salt and pepper:

When seasoning with salt and pepper, start with using half the amount in the recipe and then add more if desired. Adjust and more if desired.

Tip when using beets:

Slice the beets, soak in apple cider vinegar for 10 minutes, and then rinse with cold water. This will help the beet juices from bleeding into the other colors of the vegetables.

Tip if you do not have a rolling pin:

You can use a bottle of wine if you do not have a rolling pin.. Flour the label so the label does not stick to the dough.

Additional Notes:

*The smell of basil, mint, and lavender are natural mood enhancers!

Galette de Ratatouille


  • Blender, immersion blender, or hand wand


Pate Brisee (Flaky Pie Dough)
  • 1-1/2 cup all-purpose flour (or gluten-free flour blend)
  • 1/2 cup coconut oil (refined and solid)
  • 1-1/2 tsp. salt
  • 1/4 tsp. dried thyme (optional)
  • 1/3 cup ice cold water
Pesto Sauce
  • 1/2 cup olive oil (or your preference)
  • 2-4 garlic cloves (depending on size)
  • 1/2 cup fresh basil
  • 1 cup beet greens (removed from beets, washed, and rough chop)
  • 1/2 cup toasted pine nuts
  • 1/4 tsp. black pepper
  • 1/2 - 1 tsp. salt
  • dash of crushed red pepper flakes
  • 1 large beet (purchased with the stem and leaves)
  • 1 zucchini
  • 1 yellow squash
  • 2 large tomatoes
  • 1 red onion
  • fresh rosemary – add to the top before baking


For The Pie Dough:
  • In a small bowl, mix the flour, salt, and dried thyme.
  • In the same bowl, add the solid coconut oil, and use your fingers to break down the coconut oil into blueberry-sized pieces while incorporating it with the flour. It should resemble a crumble.
  • Use only 1 tbsp. of cold water at a time, sprinkle over the mixture while lightly kneading to form a dough ball. Once you have formed the dough ball, let it rest in the refrigerator until needed.
For The Pesto:
  • You will need a blender (any kind will do), a standing blender, an immersion blender, or a hand wand. Add olive oil, garlic, pine nuts, red pepper flakes, and basil to your blender and blend to form a paste. Then add beet greens and salt and pepper, just a little at first. Taste the pesto, if it’s to your liking then it’s done! If not, adjust with a little more salt and pepper, red pepper flakes, or parmesan cheese if your diet allows it.
For The Vegetables:
  • Thinly slice zucchini, squash, and red onions. (About 1/8 to ¼ inch thickness) set aside.
  • Thinly slice tomatoes. (About 1/8 to ¼ inch thickness). Set aside.
  • Thinly slice beets closer to 1/8 inch thickness. After slicing beets, to reduce the “bleeding,” wash in cold water with lemon juice, lime juice, or apple cider vinegar. Then pat dry.
  • Sprinkle flour on your work surface to keep the dough from sticking to the table or counter. Roll out the dough to about ¼ to ½ inch thickness. Place rolled dough on a lined cooking sheet or pizza round.
  • Spread that delicious pesto heavily on the dough, but keep away from the edges.
  • Assemble the vegetables in a circular direction, over the pesto, working from the outside to the center. See pictures. I recommend placing the beets next to the tomatoes, so they won’t bleed on the green zucchini and yellow squash.
  • Continue to assemble, working from the outside to the center until reaching the center.
  • Gently fold the edges onto itself using your finger to pinch the dough and form a crease/fold.
  • Lay fresh rosemary sprigs on top of vegetables.
  • Bake for 30 to 45 min. at 375 degrees, until the edges and crust are golden brown.
  • Finally, Bon Appetit! Enjoy!
AP flour can be substituted with Gluten-Free flour at a one-for-one ratio. You can also add 1 tsp. Chia or Flax seeds with 1 tablespoon warm water and then add this to your dough mixture, it will help to bind the dough better and add additional nutrition.
Avocado, grapeseed, or a blend can be substituted for the olive oil to suit your preference.
Pine nuts can be substituted for cashews, pistachios, or walnuts.
Nutritional Yeast can be added instead of parmesan cheese to get a fermented cheese flavor.

About Chef Petrina Peart

Chef Petrina was born and raised in Jamaica until her family migrated to the US. That early rearing as a child where she could go outside and pick fruit from a tree left a lasting impression on how she looked at food. She spent 8 years in the Air Force, and through her travels, she discovered her passion for cooking. She gained an understanding of how important food is and how it connects us all despite our different languages and cultures. During her time at Le Cordon Bleu, she gained the skills necessary to match her passion and a deeper understanding of gastronomy. Chef Petrina has been making waves in the Vegas food scene for the last 5 years, working at restaurants such as Andiron and Americana. Chef Petrina, seeing the need for vegan fine dining food in Vegas, created Gaiya’s Harvest. A pop-up dinner and small events catering concept, that also offers cooking lessons. Gaiya’s Harvest specializes in creating unique experiences by reimagining what vegan food can be.
