Heat the oil in a medium to large saucepan and sauté the onion over medium-high heat until just browning. Add the zucchini and bacon bits and continue it sauté.
1 tablespoon olive oil, 500 g of a large zucchini cut in chunks with skin, 2 tablespoon bacon bits, 1 sweet onion chopped
Once some of the zucchini starts to brown, add the broth and bring to a boil. Cook until the zucchini softens. It will depend on how large your chunks are. Mine only took about 5 minutes.
2 cups of your favorite broth
Once soft, use an immersion blender or transport the zucchini and broth to a blender. Blend until smooth then add in the cheese, thyme, a few pinches of salt and the spinach. Blend again.
5 sprigs of thyme, Kosher Salt, 3 cups of Baby Spinach
Serve with an additional sprinkle of parmesan cheese on top and a few more thyme leaves. I tried it hot, cold and at room temperature. By far I liked it warm the best but I've never been a cold soup person.
