Classic Roasted Butternut Squash and Apple Soup

Fall soup season is one of my favorite times of year.

This cozy butternut squash and apple soup brings together sweet roasted squash with tart apples for a bowl that’s both comforting and satisfying. The roasting process brings out the natural sugars in the squash while the apples add a nice fruity balance.

I like to roast everything together on one pan before blending it all up with some broth and warm spices. A touch of cream makes it smooth and rich, while a sprinkle of toasted pumpkin seeds on top adds a nice crunch.

It’s the kind of soup that fills your kitchen with amazing smells and makes everyone gather around the table on a chilly evening.

What Kind of Butternut Squash Should I Use?

Any butternut squash you find at the grocery store will work great for this soup, but there are a few things to keep in mind when selecting one. Look for a squash that feels heavy for its size and has a hard, matte skin without any soft spots or blemishes. The tan-colored neck should be long and thick, as that’s the part with the most usable flesh. If you’re short on time, many stores sell pre-cut butternut squash in the produce section, which can save you about 15 minutes of prep work. Just make sure the pieces look fresh and aren’t dried out around the edges.

Options for Substitutions

This cozy soup recipe is pretty forgiving when it comes to swaps and substitutions:

• Butternut squash: You can easily swap butternut squash with other winter squashes like acorn, delicata, or kabocha. Pumpkin works great too! Just keep the same amount and cooking time.
• Granny Smith apple: Any tart apple will work here – try Honeycrisp, Braeburn, or Gala. Sweet apples like Red Delicious might make the soup a bit too sweet, so you may want to reduce the brown sugar slightly.
• Chicken broth: Vegetable broth is an easy swap for a vegetarian version, or you can use low-sodium chicken stock. In a pinch, water with a bouillon cube works too.
• Pumpkin seeds: No pumpkin seeds? Try toasted sunflower seeds, chopped walnuts, or even croutons for that nice crunchy topping. You can also skip them entirely if needed.
• Brown sugar: Maple syrup, honey, or white sugar all work as substitutes. If using liquid sweeteners like maple syrup, start with 2 teaspoons and adjust to taste.
• Garlic powder: Fresh garlic works great too – use 1-2 cloves, minced, and roast it along with the other vegetables.

Watch Out for These Mistakes While Roasting

The biggest mistake when making roasted butternut squash soup is cutting your squash pieces too small, which causes them to burn before they caramelize properly – stick to those 1-inch pieces and give them plenty of space on the baking sheet so they roast instead of steam.

Don’t skip checking your squash with a fork after about 25-30 minutes of roasting, as overcooked squash can become mushy and watery, making your soup thin and bland rather than rich and creamy.

When blending your soup, start with less broth than you think you need since you can always add more to reach your desired consistency, but you can’t take it back once it’s too thin.

For those pumpkin seed garnishes, watch them closely during the last few minutes of toasting because they can go from perfectly golden to burnt in just 30 seconds.

What to Serve With Butternut Squash and Apple Soup?

This cozy fall soup pairs beautifully with warm, crusty bread like a thick slice of sourdough or some homemade dinner rolls for dipping. I love serving it alongside a simple arugula salad with dried cranberries and goat cheese to balance out the soup’s sweetness with something fresh and tangy. For a heartier meal, try it with a turkey and brie sandwich or even a classic BLT – the smoky bacon works surprisingly well with the sweet squash flavors. Don’t forget to sprinkle those roasted pumpkin seeds right on top of each bowl for a nice crunch that makes every spoonful even better.

Storage Instructions

Refrigerate: This soup tastes even better the next day after all those fall flavors have had time to meld together! Store it in the fridge in an airtight container for up to 5 days. I like to keep the toasted pumpkin seeds separate so they stay nice and crunchy.

Freeze: You can definitely freeze this soup for up to 3 months in freezer-safe containers or bags. Just leave a little room at the top for expansion, and make sure to freeze the pumpkin seeds separately. It’s perfect for having a cozy meal ready when the weather gets chilly.

Warm Up: Gently reheat the soup on the stovetop over medium-low heat, stirring occasionally until it’s heated through. You can also use the microwave, but I find the stovetop gives better results. Add a splash of broth if it seems too thick, and top with fresh pumpkin seeds right before serving.

Ingredients

For the soup:

• 1 small yellow onion (chopped)
• 1 Granny Smith apple (peeled and cut into 1-inch pieces)
• 1/4 tsp garlic powder
• 3.5-4.5 cups chicken broth (or vegetable broth for vegetarian option)
• 1 tsp kosher salt
• 1 medium butternut squash (2.5-3 lb, peeled and cubed into 1-inch chunks)
• 1/2 tsp ground black pepper (freshly ground preferred for more flavor)
• 2 tbsp extra virgin olive oil (I use California Olive Ranch)

For the pumpkin seed topping:

• 1 tbsp extra virgin olive oil (I use Libby’s for toasting)
• 1 tbsp brown sugar (packed)
• 1/4 tsp paprika (for color and subtle warmth)
• 1/2 tsp kosher salt
• 1/2 cup shelled pumpkin seeds (pepitas, gives a nice crunch)

Step 1: Prepare Ingredients and Toast Pumpkin Seeds

• 1 medium butternut squash
• 1 Granny Smith apple
• 1 small yellow onion
• 1/2 cup shelled pumpkin seeds
• 1 tbsp brown sugar
• 1/2 tsp kosher salt
• 1/4 tsp paprika
• 1 tbsp extra virgin olive oil

While your oven preheats to 350°F, prepare all your vegetables: peel and cube the butternut squash into 1-inch chunks, peel and chop the Granny Smith apple into similar-sized pieces, and chop the yellow onion.

In a bowl, toss the pumpkin seeds with brown sugar, kosher salt, paprika, and 1 tablespoon olive oil until evenly coated.

Spread the seeds on a baking sheet and roast for 10 minutes, stirring halfway through for even browning.

I like to toast the seeds separately first so they stay crispy and don’t get waterlogged from the squash’s moisture—this gives you that satisfying crunch in every spoonful.

Step 2: Roast Squash, Apple, and Onion

• cubed butternut squash from Step 1
• chopped apple from Step 1
• chopped onion from Step 1
• 2 tbsp extra virgin olive oil
• 1 tsp kosher salt
• 1/2 tsp ground black pepper
• 1/4 tsp garlic powder

Remove the toasted pumpkin seeds from the oven and set aside.

Increase the oven temperature to 425°F.

On a large baking sheet, combine the cubed butternut squash, chopped apple, chopped onion, 2 tablespoons extra virgin olive oil, 1 teaspoon kosher salt, black pepper, and garlic powder.

Toss until everything is evenly coated.

Spread in a single layer and roast for 35-40 minutes, stirring halfway through (around the 20-minute mark) to ensure even caramelization.

The squash should be fork-tender and the edges slightly browned when done—this caramelization is what builds the soup’s natural sweetness and depth of flavor.

Step 3: Simmer and Blend the Soup Base

• roasted squash, apple, and onion mixture from Step 2
• 3.5-4.5 cups chicken broth

Transfer the roasted squash, apple, and onion mixture into a pot and add the chicken or vegetable broth.

Bring to a gentle simmer over medium-high heat, then reduce to medium-low and simmer for 15 minutes to allow flavors to meld.

Using an immersion blender, blend the soup directly in the pot until completely smooth—I find an immersion blender works best here because it keeps the soup hot and requires less handling than transferring to a regular blender.

If you prefer a chunkier texture, you can blend it less; for silky smoothness, blend for an extra minute.

Step 4: Season and Finish the Soup

• blended soup from Step 3
• toasted pumpkin seeds from Step 1
• kosher salt and black pepper for adjustment

Taste the soup and adjust seasoning as needed with additional salt, pepper, or a splash of broth if it’s too thick.

The soup should be creamy and well-balanced—not too rich, not too thin.

Simmer gently for another 5 minutes to ensure all flavors are fully incorporated and the soup is heated through.

Ladle into bowls and top each serving with the toasted pumpkin seeds from Step 1 for texture contrast and a nutty flavor that complements the sweet squash beautifully.
