Creamy Butternut Squash Pasta Sauce (Easy 5-Ingredient Recipe)

Hi friends!
If you love creamy pasta but want something a little healthier (and super cozy), you’re going to love this Creamy Butternut Squash Pasta Sauce. It’s rich, golden, and full of flavor. And the best part? You only need five simple ingredients to make it!

This is one of my favorite fall recipes. It’s warm, comforting, and gives off major “sweater weather” vibes. Let’s get cooking!

Method:

Roast the Veggies

To start, you’ll need to prepare your vegetables. Peel and chop the butternut squash into small cubes so it cooks faster and more evenly. Then peel the onion and cut it in half, and peel the garlic cloves. Place all of them on a baking sheet. Here’s a helpful trick: wrap the onion and garlic in aluminum foil before placing them on the tray. This keeps them from burning too quickly and helps them roast more gently. Drizzle everything with a little bit of oil and sprinkle with some salt. This helps bring out the natural flavors as they cook.

Bake It All Up

Next, preheat your oven to 180°C (or 350°F) and slide the tray in. Let the veggies roast for about 30 minutes, or until the squash is soft when you poke it with a fork. You’ll notice that the squash starts to turn golden on the edges that means it’s getting sweet and ready to blend. Roasting gives everything a richer, deeper flavor compared to boiling.

Blend Until Smooth

After the vegetables are done roasting, take them out of the oven and let them cool for a few minutes. This step is important because blending hot vegetables too soon can be tricky (and steamy!). Once they’ve cooled slightly, add the squash, onion, and garlic to a blender or food processor. Then add the cashew nuts, nutritional yeast (or cheese), and a little more salt and pepper. Blend everything together until the sauce is completely smooth and creamy. If the sauce seems too thick, you can add a small splash of water to thin it out. Keep blending until it looks silky this is where the creamy magic happens!

Pour Over Your Favorite Pasta

Now it’s time for the fun part! Cook your favorite pasta penne and spaghetti work really well with this sauce. Once your pasta is cooked and drained, pour the warm, creamy butternut squash sauce over it. Mix everything together until every piece of pasta is coated in the golden sauce. You can serve it right away, and maybe even add a little extra seasoning or toppings if you’d like.

Ingredients

  • 1/2 butternut squash (peeled and chopped)

  • 1 onion (peeled and halved)

  • 5 cloves garlic (peeled)

  • 2 tbsp nutritional yeast (or swap with grated cheese)

  • 60g cashew nuts (raw and unsalted)

  • Salt and pepper to taste

Directions

  • Roast the veggies; Chop your butternut squash into cubes. Place the squash, onion, and garlic on a baking sheet. Drizzle with a little oil and sprinkle with salt.
    Pro tip: Wrap the onion and garlic in foil. This helps them cook slower and keeps them from burning while the squash gets soft.
  • Bake it all up; Put the tray in the oven at 180°C (350°F) for about 30 minutes or until the squash is soft and golden.
  • Blend until smooth; Once everything is roasted, add the squash, onion, garlic, cashew nuts, nutritional yeast (or cheese), and a bit of salt and pepper into a blender. Blend until the sauce is silky smooth. Add a splash of water if it’s too thick.
  • Pour over your favorite pasta; Cook your favorite pasta (I love it with penne or spaghetti!), then pour the creamy sauce on top. Give it a good mix and enjoy!

Notes

  • Make sure the garlic and onion are wrapped in foil. If not, they can burn before the squash is fully cooked.
  • Let the veggies cool a little before blending so the steam doesn’t pop the blender lid.
  • Blend long enough to get that ultra-smooth sauce chunky sauce just isn’t the same for this recipe.

Serving Suggestions

  • Top with crispy sage or chopped parsley for extra flavor.
  • Add roasted mushrooms or spinach to your pasta bowl for a veggie boost.
  • Serve it with garlic bread on the side for a cozy meal.
  • Sprinkle on some parmesan or vegan cheese if you want extra cheesy goodness.

Fun Fact

Butternut squash is actually a fruit! It grows from a flower and has seeds inside. And guess what? It’s packed with vitamin A, which is good for your eyes especially in the fall when days get shorter.

Conclusion

This creamy butternut squash pasta sauce is a fall favorite in my kitchen. It’s warm, comforting, and surprisingly simple. Just five ingredients and a blender, and you’ve got a cozy, healthy meal that tastes like a hug in a bowl.
