Drain the soaked chickpeas and rinse them well under cold water. Set aside.
Heat a large pot over medium heat and add the olive oil, letting it warm until shimmering and fragrant.
Add the chopped onion to the pot and sauté until it becomes soft and translucent, about 5 minutes, filling your kitchen with a sweet aroma.
Stir in the minced garlic and cook for another 30 seconds until fragrant—be careful not to burn it, as this can turn bitterness into the flavor.
Add the chopped carrots and celery, stirring well, and cook for about 5 minutes until they soften slightly and release a fresh, earthy scent.
Pour in the crushed tomatoes and stir to combine, allowing the mixture to bubble gently and thicken slightly, about 3 minutes.
Stir in the soaked chickpeas, bay leaf, thyme, and pour in the vegetable broth. Bring the mixture to a gentle boil.
Reduce heat to low, cover the pot, and let the ragout simmer gently for about 45 minutes, stirring occasionally, until the chickpeas are tender but not mushy and the flavors meld beautifully.
Remove the bay leaf, taste the ragout, and adjust the seasoning with salt or pepper if needed. The stew should be thick, fragrant, and hearty.
Serve the chickpea ragout hot, garnished with fresh herbs or a drizzle of olive oil if desired, accompanied by crusty bread or grains.
