Description
This easy pumpkin and cauliflower soup recipe is designed for bulk cooking and freezing in portions — so you can make once and enjoy many times. You’ll cook a large batch of smooth, creamy soup that freezes beautifully, then turn each portion into a different 15-minute dinner when you’re ready to eat.
Ingredients
- 2 tbsp olive oil
- 2 leeks, washed (see how to clean leek post) and sliced (white and light green parts only)
- 2 onions, diced
- 4 cloves garlic, crushed
- 1 medium cauliflower (about 1 kg/2.2 lb), chopped
- 1 kg peeled fresh pumpkin (about 2.2 lb), diced. Can use butternut pumpkin (butternut squash) or sugar pumpkins/pie pumpkins
- 8 cups (2 L) vegetable and/or chicken stock
- Salt and black pepper, to taste
Instructions
Cook the Soup
- In a large pot, sauté onion and leek in olive oil over medium heat until soft and fragrant, about 8 minutes. This builds the flavour base for the soup.
- Add crushed garlic and stir gently to release its aroma, cooking for 1 minute. This adds depth and a savoury note to your base.
- Add chopped pumpkin and cauliflower, tossing evenly in the aromatics to coat each piece and help draw out flavour as they cook.
- Pour in vegetable and chicken stock, stirring gently to combine all ingredients. Bring to a gentle boil, then reduce to low heat to simmer.
- Simmer over low heat until the pumpkin and cauliflower are tender and soft throughout — about 25–30 minutes, depending on cut size.
- Blend the soup until smooth and creamy using a stick blender or regular blender. Taste and season with salt and pepper as desired.
Portion and Freeze for Meal Prep
- Place your empty pot or container on a kitchen scale and press tare (reset) to zero. Pour in the soup to weigh the total content only.
Tip: Note the total weight — you’ll use this to decide your portion sizes. - Decide how much soup you want per portion. For example, 300 ml / 1¼ cups suits one person, while 600 ml / 2½ cups suits two.
If your soup weighs 4500 g / 4.5 kg (about 10 lb), you’ll get around seven 600 ml / 2½ cup portions. Refer to note 1 for portion chart - Prepare your freezer bags by placing each inside a glass jar to hold its shape upright. This keeps the bag stable and makes pouring easier.
- Pour soup carefully into the bag using a wide-mouth funnel if needed. Weigh each filled bag to ensure consistent portions, sealing or setting aside as you go.
- Seal each bag using a food-safe sealer set to the moist mode. Press “seal,” not “vacuum,” to avoid pulling out liquid. You can also use zip-lock bags or freezer-safe containers.
- Lay sealed soup bags flat on a tray to freeze overnight until solid. Once frozen, stack them flat or upright to save freezer space and keep everything tidy. Refer to note 2 for vacuuming
Notes
- Perfect Batch Example
My total soup weight: 4500 g / 4.5 kg (about 10 lb)
That’s the batch size for this recipe. Here’s how I portion it evenly so there’s almost no waste and it fits neatly in the freezer.7 × 600 g / 2½ cup portions – perfect for two people or generous meal prep serves. If you have a little leftover simply divide it evenly between portions or freeze it as a small single-serve portion.
or
6 × 750 g / 3 cup portions – hearty, family-size portions for dinner. - If you like, you can then cut open the top seal and vacuum-seal the frozen soup for longer storage — it’s best to do this only once the soup is solid, as vacuuming unfrozen soup will pull liquid into the sealer.
