Want a great potato soup with ingredients you love? This gluten free roasted potato soup with mushrooms is rich, thick and packs tons of flavor. No gluten, no dairy, just healthy deliciousness! Perfect for #MeatlessMonday too.
I’m wearing a hat and scarf in my house right now. No gloves. Still, we’re getting some nasty, cold weather here in central PA.
And there’s no better antidote to nasty, cold weather than a big bowl of hot potato soup.
But the potato soups I always made in the past used wheat flour as a thickening agent, and I’m pretty serious about avoiding gluten these days. My priorities are, in order: 1. be happy 2. everything else, and gluten doesn’t make me a happy camper.
I’ve been fooling around in the kitchen and came up with a gluten free, dairy free, vegetarian (obviously) potato soup that packs ridiculous heaps of roasted potato and veggie flavor. Plus it’s thick, creamy, tastes nice and rich and satisfies me down to the toes. Which are quite frosty at the moment, despite the wool socks.
Turns out making a thick, luscious, creamy potato soup gluten free is incredibly easy. I just replaced the wheat flour in my back-in-the-day favorite potato soup recipe with Bob’s Red Mill All Purpose Gluten Free Flour. I think any gluten free flour blend you want to use will work well.
Gluten free cooking tip: gluten free flours are made of starches. Starch is what thickens stuff (think cornstarch). The protein in wheat flour, aka gluten, does diddly squat to thicken anything. So there’s absolutely no magic in wheat flour that makes it essential for thickening potato soup, or any soup. That deserves a woot. Woot!
You can use white or Russet potatoes for sure, both are good. The skin on white potatoes is a little finer so I slightly prefer them, but only slightly. And only when they’re on sale and cheaper than Russet, which is rare.
I’d like to try this soup with red potatoes at some point. If you do, leave a comment or hit me up on Facebook and let me know how it came out. I don’t know what my deal is, I never want to spend the extra buck or so on red potatoes. If you convince me that it’s worth it, I’ll give them a try.
Roasting the potatoes before adding them to the soup gives them a little bit of a crispy crust, and aye carumba is that good!
I’ve made a lot of potato soup where the potatoes kind of dissolve into the broth, and I don’t love that effect. I want my potatoes tender yet solid and flavorful, which gave me the idea of roasting before adding them. I more or less follow Ina Garten’s method for garlic roasted potatoes, not just because I’m an Ina fangirl but partly. They carry that nice roasty texture and all that gorgeous garlic roasted flavor right into the soup!
Mushrooms in potato soup is a natural to me. I freaking love mushrooms. But they’re not just in there because they’re my pet veggie.
Mushrooms are almost no calorie and a great source of antioxidants. And those little rhizomes they poof out when they’re cooking have an amazing way of thickening stuff up. Perfect for a gluten free potato soup. They also add depth of flavor, that crucial umami experience that vegan food occasionally lacks.
I highly recommend cremini mushrooms because they have lots of flavor. Buttons are good too, but not as good. Sorry buttons.
Without the mushrooms, this would be a very good potato soup. With the mushrooms, I’ll lick the bowl if no one’s looking. I might lick it anyway even if they are.
When I’m having a great soup, I need at least one slice of bread to mop the bowl with. I’m onto a great gluten/egg/dairy free bread at the moment, Ener-G’s Light Tapioca Loaf . It’s dairy, egg and gluten free and has a light, airy texture. And not to get fancy on you, but it tastes like bread. And it’s just so damn handy in soup weather to be able to grab a slice of bread when I want it, especially during soup season.
