To make kale chips, increase oven to 425F. Line two large baking sheets with parchment and divide the kale ensuring they are spread evenly. Toss each with 1 tbsp of olive oil to coat. Bake until crisp about 6-7 minutes turning over.
Remove from oven and sprinkle with flaked sea salt and let cool.
To make garlic oil, place oil and garlic in a small sauce pot. Cook over medium heat until oil starts to sizzle. Remove from heat and let stand until ready to use.
To make soup, preheat oven to 400F and line a large baking sheet with parchment paper.
Cut parsnips into 1 inch size pieces. Place parsnips and onions on baking sheet and toss with olive oil, salt and fresh ground pepper. Bake for 20-25 mins until parsnips have softened.
Add parsnips, onions, celery, leaves and 3 1/2 cup vegetable stock in a food processor or blender. Blend until smooth and creamy.
Place in soup pot and heat until hot. Here you can stir in additional 1/2 cup vegetable stock for your preferred consistency in thickness of soup. Stir in lemon juice and season with additional salt and fresh ground pepper to taste.
To assemble, place soup in bowl and top with kale chips. Drizzle top with garlic oil and sprinkle with aleppo pepper and za'atar.
