Preheat your oven to 375ºF and line a baking sheet with parchment paper.
Spread the carrots over the baking sheet and roast for 40 minutes, tossing halfway through cooking.
In a large pot, heat 2 Tbsp of vegetable broth. Add the onion and celery, cook for 7-10 minutes or until softened. Then add the garlic and cook for 2 to 3 more minutes.
Add the roasted carrots, vegetable broth, white beans, turmeric, and tahini into the pot. Use an immersion blender to puree until completely smooth. Add lemon juice and pepper to taste.
Pour into a bowl and enjoy!
