This gorgeous fall soup is a healthy, fiber and protein-packed and in my humble opinion, the absolute best butternut squash soup recipe. It looks so sophisticated, but is actually so simple! Made with just a few simple ingredients (with dairy-free and gluten-free options) and garnished with sour cream and crispy black beluga lentils. A delicious and easy fall recipe that looks (and tastes!) like fall in a bowl.

Why you'll love this Butternut Squash Soup

  • Nutrition- Between the butternut squash and the black lentils, this soup is packed with antioxidants, vitamins A, C, E, fiber and protein.
  • Plant Based- If you're looking for vegetarian dinner recipes, use vegetable stock for a great veggie packed option!
  • High protein meal prep- This is a great recipe if you are trying to make your meals for the week, and pack in the protein, this is a great option.
  • Dairy free and gluten-free- Roasted butternut squash is naturally sweet and creamy so there is no need for cream.
  • Freezer Meals- It can be divided into portions and frozen for up to 4 months, then reheated when you need a quick and easy dinner or lunch.
  • Crispy Black Beluga Lentils- This black lentils recipe is my new favorite thing! I am trying to figure out where else to use them. If nothing else, they are just a great, high fiber and high protein snack by themselves!
  • Fall aesthetic- If you are looking for fall recipes, or a dish for a Halloween party, here you go!

Ingredients

  • Butternut Squash- Use the freshest squash you can, and look for squash with a dull (not shiny) skin and one that feels heavy for its size.
  • Chicken or Vegetable Stock- Use vegetable stock if you'd like to keep it vegetarian or vegan.
  • Shallot- Just one bulb, so half of a full shallot.
  • Garlic- A few whole cloves with the skin on.
  • Fresh Thyme- This adds a soft herbal essence that is so nice with squash.
  • Pumpkin Pie Spice- We use just a tiny bit to add that warm spiciness that will make it smell and taste like fall.
  • Brown sugar- This enhances the natural sweetness just a bit.
  • Salt- To bring out all of these great flavors.
  • Butter- Just a little bit of butter adds so much rich creamy decadence to this soup.
  • Black Lentils and Sour cream- These are used for the garnishes. Not only do they add great flavor, but also texture, crunch, and a beautiful Halloween aesthetic!
Ingredients for butternut squash soup.

How to cook butternut squash

There are tons of different ways to cook Butternut Squash. It can be cubed and roasted, it can be roasted whole, or as we are doing in this recipe, it can be halved and roasted.

By cutting the squash in half and roasting, it keeps the moisture in and creates a creamier, moister (ew, sorry), and more tender squash which is the perfect texture for using in a Butternut Squash soup.

Not only does this method work well for soup, but it is also incredibly easy and a lot less time consuming, and labor intensive than having to peel, cut, and cube the squash. So it is a win all around!

Option 1: Roasting butternut squash halves (recommended)

To cut the squash, cut ยฝ inch off of the top and bottom so that both ends are flat. This will give you a sturdy end to stand the squash on while you cut it in half the long way.

Cutting butternut squash in half.

Scoop out the seeds and the stringy part and toss, (or set aside to roast later!).

Rub cut sides with olive oil and sprinkle them with a little salt and pepper. Then place the squash, cut side down on a baking sheet or baking dish.

In the little indent in the squash, where the seeds and stringy part was, place the garlic cloves and shallot. This little cave will help roast soft and creamy garlic and shallots that you don't even have to peel! They will cook in their skin and then will be soft and easy to peel when they are cooked.

Roast in a 400ยฐF preheated oven for 45 minutes. After 45 minutes, use a knife to pierce the squash to check its doneness. The skin should be slightly browned and the knife should easily slice all the way through the squash.

Option 2: Roasting diced butternut squash

These days, there are so many places that you can buy already peeled and cubed butternut squash. How nice is that!? So if you'd like to go this route, easy peasy!

Toss 4 cups of cubed squash with a couple tablespoons of olive oil, salt and pepper and the fresh thyme leaves.

Place it on a parchment lined baking sheet with the whole (unpeeled) shallot and garlic cloves.

Roast in a 400ยฐF oven for 25-35 minutes, until you can easily pierce a piece of squash with your fork.

Option 3: Microwave option

I would recommend one of the oven roasting methods if at all possible. However, if you would rather, you can microwave the squash.

To do this, cut and prep the squash as instructed above. Then, place it cut side down on a microwave safe plate and microwave on 100% power for 15-20 minutes, checking the squash every 5 minutes. When the flesh is soft and easily pierced with a knife, all the way through, it is done.

How to make crispy black lentils

These are so easy to make, and feel like tiny crispy bubbles that add such good crunch and texture to contrast the creaminess of the soup.

Simply soak ยผ cup of black beluga lentils in water overnight (at least 8 hours and no more than 24).

Then, drain them and shake them dry on a towel.

Heat a large sautรฉ pan (so the lentils are in a single layer), over medium high heat. Add ยฝ cup olive oil (or your preferred oil). Toss a single lentil into the oil to test if it is hot enough. If the lentil sizzles, it is ready.

Add the lentils and stir them to make sure they are all in the oil. Let them sizzle for 5 minutes until they feel crisp when you stir them. They shouldn't be soft or chewy at all, but light and crisp and with an airy pop when you bite them. This should take about 5 minutes, but let them cook until they are crisp.

When they are done, place the lentils on a paper towel to let them cool and absorb any extra oil. They will get crisper as they cool. Set them aside until it is time to serve and garnish your soup.

How to make this fall soup

Once the squash, garlic and shallots are roasted, place the butternut squash flesh, and peeled garlic and shallot in a high powered blender. Add in the salt, pumpkin pie spice, brown sugar, and chicken stock and blend on medium high speed for 1-2 minutes, until everything is blended and smooth.

Start with 2 cups of stock, and then slowly add more until you are happy with the consistency.

At this point, you can place the soup in a sealed container and put it in the fridge for up to 2 days. When you are ready to serve, heat it over medium heat in a large saucepan.

Once it is hot, add the butter and stir in until it is melted and well blended into the soup.

How to garnish this soup

This soup is so much fun because it is naturally fall colored! Then, add the sour cream and crispy black lentils to create the perfect dish for your halloween dinner party!

Check out this Roasted Beet Hummus, for another naturally brightly colored dish!

Top soup with about a teaspoon of sour cream, and about a tablespoon or two of the black lentils. Serve while it's hot and enjoy!

Dietary options

  • Dairy Free- To keep this soup dairy free, skip the butter, or instead add a tablespoon of coconut oil. This may alter the flavor a tiny bit, but it will still be delicious. Instead of the sour cream, use a vegan sour cream, cashew, soy or coconut cream.
  • Vegan- Simply use vegetable stock in place of the chicken stock, and coconut oil in place of the butter.

Frequently asked questions

Can I freeze butternut squash soup?

Yes! You sure can. Put it in a freezer safe ziplock bag, or snap lock container, being sure to leave a little room for expansion. It can be frozen for up to 3 months. Thaw it in the fridge overnight, and warm it in the microwave or in a saucepan on the stove.

How long do the crispy black lentils last?

In my experience they don't last long....before they all get eaten! But as far as storage goes, at room temperature, as long as there's no moisture and they are in a sealed container, they will stay fresh and crisp for up to a week.

Is butternut squash healthier than potatoes?

Yes, it is considered healthier than potatoes because it is lower in calories and carbs, and higher in fiber and vitamin A.

    Full of flavor and warm spices-perfect for the cool fall weather. The black beluga lentils add a fun little pop of texture! (Made us feel fancy.) Wish I had some rustic bread to dip in.
