What Kind of Pumpkin Should I Use?

You can absolutely use canned pumpkin puree here — it’s convenient, smooth, and reliable. Just make sure you’re buying pure pumpkin, not the pre-spiced pumpkin pie filling. If you have time and want to go the homemade route, roasted sugar pumpkins are ideal. They yield a naturally sweet, velvety texture that adds a deeper flavor dimension. Avoid large carving pumpkins, which tend to be watery and bland.

Options for Substitutions

Dairy-Free Cheese: Use your favorite dairy-free cheddar slices for the grilled cheese if you want a vegan version.
Coconut Milk: Instead of cream or whole milk, use full-fat coconut milk for an extra rich, dairy-free alternative.
Butternut Squash: No pumpkin? No problem. Butternut squash works beautifully as a swap.
Spice Control: Adjust the chili flakes or hot sauce to tone down or amp up the heat.
Gluten-Free Bread: Gluten-free bread works just as well for the croutons if needed.

Ingredients for this Spicy Pumpkin Soup with Grilled Cheese Croutons

Pumpkin Puree – The heart of the soup, giving it a naturally sweet and earthy flavor while providing a creamy, velvety base.
Yellow Onion – Adds depth and a savory balance to the sweetness of the pumpkin.
Garlic Cloves – For an aromatic punch and essential flavor foundation.
Fresh Ginger – Brings a warm, zesty kick that complements the spice and balances the richness.
Vegetable Broth – Creates the liquid base; go for low sodium to control salt levels.
Coconut Milk or Heavy Cream – Adds richness and a silky texture; coconut milk also introduces subtle sweetness.
Olive Oil or Butter – For sautéing the aromatics and adding body to the soup.
Red Pepper Flakes or Hot Sauce – Delivers the spicy element and can be adjusted to taste.
Salt & Black Pepper – Essential seasoning to tie everything together.
Fresh Thyme or Sage (optional) – Herbs add an earthy, aromatic layer that enhances the flavor complexity.
Cheddar Cheese – For that gooey, melty texture in the grilled cheese croutons.
Sourdough or White Bread – Thick slices hold up well when grilled and cut into croutons.
Butter (for grilling) – Ensures golden, crispy exteriors on your grilled cheese sandwiches.

Step 1: Sauté the Aromatics

Heat olive oil or butter in a large pot over medium heat. Add chopped onion and cook until soft and translucent, about 5–6 minutes. Add minced garlic and ginger and cook for another minute until fragrant.

Step 2: Build the Flavor

Stir in the red pepper flakes (or hot sauce) and a pinch of salt. Let the spices bloom for 30 seconds, then add the pumpkin puree and stir well to combine with the aromatics.

Step 3: Add the Broth

Pour in the vegetable broth and stir until everything is evenly mixed. Bring the soup to a simmer and cook for about 15 minutes, allowing all the flavors to meld.

Step 4: Blend the Soup

Use an immersion blender directly in the pot to blend the soup until smooth. Alternatively, let it cool slightly and blend in batches in a high-speed blender. Return to the pot.

Step 5: Stir in the Cream

Lower the heat and stir in your coconut milk or cream. Let it warm through, then taste and adjust seasoning with salt and pepper. Add more spice if desired.

Step 6: Make the Grilled Cheese

While the soup simmers, butter your bread slices and sandwich cheddar cheese between them. Grill in a skillet over medium heat until golden and crispy on both sides, and the cheese is melted. Let cool slightly, then cut into bite-sized croutons.

Step 7: Serve It Up

Ladle the hot soup into bowls and top each with a handful of grilled cheese croutons. Garnish with black pepper, fresh thyme or sage if desired, and serve immediately.

How Long to Prepare Spicy Pumpkin Soup with Grilled Cheese Croutons

Prep Time

Preparing this cozy dish takes around 15 minutes. Chopping the onions, garlic, ginger, and getting your grilled cheese ready will be your main tasks. If you’re using canned pumpkin, you save a good chunk of time.

Cook Time

The soup itself needs about 20–25 minutes to simmer and blend, while the grilled cheese sandwiches take about 5–7 minutes to prepare and grill. Altogether, the recipe should take no more than 40–45 minutes from start to finish.

Tips for Perfect Spicy Pumpkin Soup with Grilled Cheese Croutons

For extra flavor depth, sauté the onions low and slow until lightly caramelized.
Use a high-powered blender for an ultra-smooth texture if you’re not using an immersion blender.
Fresh ginger makes a difference — grate it finely so it distributes evenly in the soup.
Toast the grilled cheese slightly more than you would normally so they stay crisp longer in the soup.
Add a swirl of cream or coconut milk on top just before serving for visual appeal.

Watch Out for These Mistakes While Cooking

Using pumpkin pie filling instead of pure pumpkin puree — it’s already sweetened and spiced.
Overheating the dairy — coconut milk or cream can curdle if boiled; keep the heat low after adding.
Adding croutons too early — they’ll get soggy quickly. Add them just before serving.
Under-seasoning — always taste and adjust for salt and heat before serving.
Skipping the blend — a chunky soup won’t give you the same velvety experience.

What to Serve With Spicy Pumpkin Soup with Grilled Cheese Croutons?

1. Autumn Harvest Salad

A mix of arugula, apples, cranberries, and walnuts with a light vinaigrette complements the richness of the soup.

2. Roasted Brussels Sprouts

Their earthy, caramelized flavor plays nicely against the creamy soup.

3. Apple Cider or Sparkling Juice

A non-alcoholic drink pairing that enhances the fall flavors.

4. Maple Glazed Carrots

Sweet, tender carrots with a hint of maple provide a lovely side.

5. Crispy Roasted Chickpeas

Add them on the side or even on top of the soup for extra crunch and protein.

Storage Instructions

Refrigeration

Allow the soup to cool completely before transferring to an airtight container. Store in the refrigerator for up to 4 days. Reheat gently over low heat, adding a splash of broth or water if it thickens too much.

Freezing

The soup (without croutons) freezes beautifully. Pour into freezer-safe containers or bags, leaving space for expansion. Freeze for up to 3 months. Thaw overnight in the fridge and reheat on the stove.

Grilled Cheese Croutons

Best made fresh, but you can store leftover sandwiches in the fridge for 1 day. Reheat in a skillet or oven to crisp them back up before cutting into croutons.
