Three bowls of Thai Pumpkin Soup with toppings

This soup is a bit of a departure for me. As a food blogger and home cooking advocate — and particularly as a vegetable gardener — I feel some responsibility to present recipes that encourage fresh food prep and hands-on cooking, in a way that’s approachable and doesn’t inspire dread.

Not whole foods cooking, exactly, but a reasonable compromise between completely from scratch, and dumped from a can. My general approach to recipes includes an expectation that the cook is okay with chopping some vegetables and has a reasonably stocked pantry of seasonings, condiments, legumes, proteins, etc.

My recipes are usually under an hour (unless there’s hands-off simmering involved). I don’t use restaurant techniques — you won’t find diffusers or sous vide devices in my kitchen — but my recipes are fully seasoned, and do use steps that layer flavors in a way you simply can’t find in fast food or off-the-shelf grocery store products.

So I have, somewhat intentionally, completely skirted shortcut recipes. No matter how my day has gone, I’m simply not the kind of cook who dumps cream-of-something into the Instant Pot and calls it dinner.

But, that doesn’t mean that every single meal I prepare is a full-on cooking situation. I take short-cuts, too. Not cream-of-something shortcuts, but thoughtfully planned and researched alternatives that skimp on time, not flavor. It’s time that I share these recipes. Past time.

Steps to cook Thai Pumpkin Soup

Normally, I might’ve created this recipe for the blog using roasted pumpkins and the full complement of Thai seasonings. Instead, I’m stepping out of my blogger’s comfort zone and sharing how I first made this recipe, for myself, for a quick dinner. Four easy steps (see photo above) and done.

Shortcuts for Making Thai Pumpkin Soup

  • Onions – okay, there’s no shortcut here, lol. It’s one of my uncompromisable ingredients: chopped onions. I’ll admit that prepping onions is one of my cooking super powers: I can peel and dice an entire onion in under a minute. If you need some tips for honing your onion chopping skills, check out my onion slicing tutorial. This is the most hands-on part of the soup, so once you finishing chopping, things move fast.
  • Garlic – if you hate handling fresh garlic, you’re not alone, so let me put that particular dread to rest: garlic powder is okay. Especially if it’s organic. Garlic powder (or the slightly coarser granulated garlic) is made by dehydrating fresh garlic cloves and grinding them to the proper consistency. I grow my own garlic, and make my own powder (yes, I’m one of those gardening nerds, lol). This recipe uses garlic powder, but feel free to substitute with two minced cloves of fresh garlic.
  • Thai red curry paste – this is just good stuff, plain and simple. My local grocery store gives me the choice of exactly one brand, but there are several high-end brands that can be found in places like Whole Foods (or on Amazon). It contains the addictive combination of red chile peppers, galangal, lemongrass, shallots, and more. Most brands are packed in 4 ounce containers. You’ll use about half of that.
  • Ginger paste – ginger paste should be readily available in the produce section of your grocery store. Note that some brands add sugar. I use one of those brands, but wanted to be sure to point it out, in case added sugar is a problem. Handling fresh ginger is not a big deal, but it’s weird with its papery skin and fibrous root. Weirdly wonderful, but, prepackaged paste is a good substitute.
  • Lemongrass paste – lemongrass paste is always in my fridge. Always. Fresh lemongrass is highly seasonal where I live, and when I can find it, I rarely consider it worth the effort. I don’t feel guilty at all about using lemongrass paste, and you shouldn’t either. Find it in the produce section, usually with the refrigerated herbs.
  • Pumpkin Puree – As I said, my blogger instincts might normally call for a roasting of a pie pumpkin. But, a can of pumpkin puree is perfectly acceptable. Look at the ingredients on the can: there should be one, pumpkin. Buy the can and feel good about it. I do.
  • Vegetable broth – would it surprise you to learn that I buy broth from the store? Like, a lot of store-bought broth. I’m the first person to extol the virtues of homemade broth, but I’m also a realist. Before a recipe is posted here on SoupAddict, it’s tested at least three times, which means I’m cooking soup for dinner during the week. A lot. I go through a ton of broth. Weekend broth-making is great, and it’s even fairly fast in a pressure cooker, but I’m not about to finish the day at my corporate job by firing up a batch of vegetable broth before even being able to start dinner for the night. Store-bought broth is perfectly fine, with cautions. Read the labels, understand sodium levels. Pay attention to ingredients – most are made with oils. There are big differences between brands: experiment to find the one you like. I actually prefer my store’s name brand broths. They’re less intensely brothy, which gives me more control over the end flavor of the soup.
  • Coconut milk – cracking open a whole coconut to create coconut milk is one thing I’ve never done, lol. I exclusively use canned, unsweetened coconut milk for cooking. Usually full fat, unless shopping finds me in a guilty mood. Like broth, there are often significant differences between brands. Not necessarily in flavor, but in ingredients. I usually go for as few as possible. Why canned? Boxed coconut milk is made for drinking and usually contains an eye-opening list of ingredients. Plus, full fat coconut milk comes with a ring of irresistible coconut cream around the edges. Any soup you see on this site with white designs on the surface (such as in these photos), was made with coconut cream scraped from the can.

As you’ll see in the recipe, Thai Pumpkin Soup comes together in a just a few super simple steps. But don’t forget the toppings! They’re optional, of course, but garnishes can take an already great soup and send it right over the top.

Toppings for Thai Pumpkin Soup:

  • Cilantro: Fresh cilantro is a natural choice to pair with Thai-leaning cuisine. If you have cilantro avoiders in the house, serve it on the side, or just skip it altogether. I don’t recommend substituting flat-leaf parsley, as it’s a bit strong. Fresh Thai basil would be nice, though, if you have access to it.
  • Green onions: The easiest of easy prep: buy a bunch at the store. Wash them off and peel off any loose or wilty layers. Remove the root end, and then slice thinly on the diagonal. Also, if your store has a salad bar, check to see if they have pre-sliced green onions. I often raid the salad bar when I make soup.
  • Chile peppers: If you and your people love things spicy hot, top the soup with slices of hot chile peppers, such as jalapenos (hottish), Fresnos (hot), or Thai bird or habaneros (yeowza).
  • Crushed red pepper: For a more controlled heat, sprinkle some crushed red pepper flakes over the soup. Aleppo pepper is quite lovely, too (although not spicy).
  • Seeds: If you enjoy crunch with your soup, scatter some seeds over the top. Sunflower or pepitas are particularly nice, as their nutty flavors go really well with this soup. For extra oomph, make a batch of my Honey Sriracha Roasted Pumpkin Seeds, which is both soup topping and awesome snack!

The irony here is that it probably took you longer to read this post and its tips than it will be to make the soup. Thank goodness! 😀

Oh, and Thai Pumpkin Soup is make-ahead awesome, so don’t hesitate to make it the day before a busy evening, or enjoy leftovers for lunch the next day. It’s creamy, flavorful, and satisfying.

I never heard of lemongrass paste before. If a recipe calls for 3 stalks of lemongrass, how much of the paste would you use in place of the stalks? This will be much easier for me to find year round. thank you in advance.

Keeping it real. Thank you for that! Some online recipes are just so overwhelming with all of the steps or hard to find ingredients. This looks easy and delicious.

So hoping one of the soups you'll post soon is Mock Turtle. While still feeling like summer here in SW Ohio, fall will be here before we know it. At least I hope fall is here before we know it. Sort of worried winter will come without experiencing autumn. Would love to have your Mock Turtle soup recipe to add to our menu.

I can't believe you posted this! :D Mock Turtle soup is definitely on my upcoming list, I just have to photograph everything. My mom's Mock Turtle soup is one of the consistently great food memories of my childhood. Stay tuned!

And about the weather, I'm worried about that, too. We're breaking all sorts of heat records this week, and I'm afraid that it will move out ... and then it will snow, lol. The trees in my yard aren't even bothering to turn color - the leaves are just browning up and dropping off.
