How to Make Easy Roasted Butternut Squash Soup

Butternut squash is all the rage right now, and for good reason. It’s tasty, healthy, and easy to cook. Butternut squash soup can be found at fancy restaurants, weddings, etc. but you don’t need a fancy event to enjoy it. You can make the creamy soup right at home with this easy roasted butternut squash soup recipe!

Honestly, it’s so simple. Anyone could follow this recipe. I make it quite often, my kids devour it, and it’s super healthy. Butternut squash is chock full of vitamins, not to mention the other awesome veggies you can sneak in such as celery, peppers, and carrots.

So, buckle up. All you need are some fresh veggies, herbs and spices, a pan, broth and a blender to make this delicious, creamy soup.

What You’re Going to Need:

Phase One
  • 1 bag of frozen, diced butternut squash. I buy the pre-chopped frozen stuff because it’s easier. And when it’s on sale I can stock up and fill my freezer.
  • 1/4 tsp of rosemary. You can use more if you really love it.
  • 1/4 tsp salt. Try and limit your salt because the broth will have it.
  • 1/2 tsp of garlic powder
  • pinch of red pepper flakes. Less is more when it comes to these. If you like it spice, add more, by all means. But their effect increases when cooked.
  • 1/4 tsp of black pepper
  • olive oil
  • 2 cups of broth. You can use the store bought stuff. Personally, I make my own broth at home and freeze it. That way, I avoid preservative and the high sodium levels. Also, it doesn’t matter which kind. I used vegetable broth for this, but you can go chicken if you prefer.
  • 3 full carrots
  • 1/2 a bunch of celery
  • 4 cloves of garlic. If you or anyone in your household is suffering from a cold, add even more garlic to help!
  • 1 sprig of green onion
  • a medium sized roasting pan
Phase Two
  • large pot
  • blender. I used a Magic Bullet, but anything that blends will do the job just fine.


Step One

Preheat your oven to 350 degrees Celsius.

Step Two

Gather all of your ingredients in one place. Then take your carrots, green onions, celery, and garlic and wash your veggies thoroughly. Then, begin to chop them into tiny, bite sized pieces. The smaller you chop them, the quicker they’ll cook.

Step Three

Take your expertly chopped veggies and add to the roasting pan. Open your bag of frozen and diced butternut squash and dump those in there, too. Stir them around to get a good mixture.

Step Four

Now you can add your herbs and spices. If you prefer some over the others, you can definitely add more. The ones I used are just common to this recipe. But I’ve seen people add in curry, thyme, and even jalapenos. Then, stir around to make sure your veggies are as coated as they can be.

Step Five

Next, add your olive oil. I never tell people how much to add, because it all depends on the person. Obviously, the more you use, the oilier your roasted veggies will be. If that’s not what you’re going for, then only drizzle the surface, stir around to get decent coverage, and then add ¼ cup of water to prevent drying out during the baking process. Myself, I love olive oil. It makes the veggies nice a soft.

Step Six

Now that you’ve got the ingredients all prepared, cover your roasting pan and stick it in the oven on 350 degrees for about an hour. Taking it out periodically to stir and check if it needs extra oil or water. After about an hour, assess whether or not they’re soft enough (this will depend on the size you chopped your veggies). You want them to be fairly mushy, so they will easily blend in the blender.

Step Seven

Once that’s done and your vegetable mix is good and mushy, set it aside and let cool. To expedite this process, transfer the ingredients to a new dish and stick in the fridge. Reason being, is that you can’t blend super hot foods. (trust me, I learned the ward way!)

Step Eight

Now you’re ready to start blending your soup! If you’re using a large blender or mixer, feel free to add the whole lot and dump in your broth, blending until you get a nice, creamy consistency.

Myself, I used a Magic Bullet, so I had to do small portions at a time. I added a few spoonful’s of my roasted vegetables, plus enough broth just to cover it. Mixed until creamy and smooth and then dumped into my large cooking pot. I repeated this until I had mixed all the ingredients.

Step Nine

Once all of your ingredients are in the pot, add any remaining broth to it and stir. Cook this on a medium-high heat until it begins to bubble. This really fuses together all the different tastes and makes the final result so much creamier.

Step Ten

Voila! Your homemade roasted butternut squash soup is done and ready to enjoy. If you like things on the spicier side, sprinkled some extra red pepper flakes on top before diving in.


And there you have it! This homemade roasted butternut squash soup recipe is foolproof. Seriously, anyone can toss veggies in a pan and then blend them up. And, I promise you, this is the best, creamiest, soup you will ever eat. It’s my go-to comfort food during the colder months and my kids absolutely love it. What more could you ask for? And one of the best things about this recipe is that you can spend the day making a large batch and divide into containers to freeze! They’d make great on-the-go lunch ideas, or a smart and quick meal when you’re not in the mood to cook.
