Calories: 143kcal

Author: Oh My Veggies

Ingredients

1 large acorn squash
2 tablespoons olive oil divided
¼ teaspoon ground cinnamon
½ teaspoon kosher salt or to taste
1 medium yellow onion chopped
3 cloves garlic minced
2 cups unsweetened almond milk
2 cups vegetable broth
Sour cream or plain Greek yogurt for serving optional

US Customary - Metric

Instructions

Preheat the oven to 375ºF.
Chop the tip and tail off the acorn squash, then cut it in half length-wise. Scoop out the seeds and discard them (or you can roast them like pumpkin seeds--they're delicious!).
Drizzle the squash flesh with 1 tablespoon of olive oil and sprinkle with salt and cinnamon. Place both squash halves on a baking sheet, cut-side down. Roast the acorn squash for 45 to 50 minutes, or until the flesh is very soft. Use a spoon to remove the squash flesh from the skin; discard the skin.
Heat the remaining olive oil in a skillet over medium heat. Add the chopped onion and sauté until browned, about 15 minutes. Add the garlic and sauté an additional 2 minutes. Remove from heat.
Add the squash, sautéed onion and garlic, almond milk, and vegetable broth to a blender and blend until completely smooth. Season to taste with salt and pepper and serve with sour cream or plain Greek yogurt, if desired.

Notes

If you have an immersion blender, you can cook the onion and garlic in a Dutch oven, then add the remaining ingredients and blend directly in the pot.

Hi Julia,
I just read your sentence with the "strüsel to your küchel" five times until I got the idea even though I am German 😉 There's a cake in Germany, which is called "Streuselkuchen". "Kuchen" being the cake and "Streusel" being crumbles. So it's a crumble cake, in fact. And without crumbles no crumble cake 😉
So "Streusel" are crumbles and you could also put them on a "Küchle" (to stay with the "Ü"), which would be a smallish, flat cake or pastry. 🙂

  Hi Kirsten! I'm so sorry to hear the soup didn't work out for you! I enjoy the mild flavor, but can understand the desire for something more robust. I also make this recipe using 1 cup of full-fat coconut milk in place of the almond milk, which makes it more rich, and add a little more veggie broth. I recommend adding salt to taste in soups because that always makes a big difference! 🙂 My apologies again, and let me know if you take another swing at it. 🙂

  Not sure what you mean - it says to add the broth and almond milk in the very last step of the recipe. The soup doesn't require cooking down.

The soup was great!! I added sweet potatoes and instead of almond milk (which I didn't have) I used evaporated milk. Such a versatile soup/recipe, there are so many things you can add or do to the soup to suit your tastes! Next time I am going to add some kale or spinach 🙂
