OMG WE HAD OUR FIRST COLD FRONT!

Laugh all you want, but this is the highlight of the year for us Floridians who run the risk of heat stroke through most of Fall.

Florida Fall Heat Stroke

We don’t wear flip flops in the Fall just to make Northerners cringe, it’s out of sheer necessity! Wearing them in Winter is an entirely different story… don’t judge my hoodie and flops.

Now that there’s officially a chill in the air, the soup kick that I’ve been on since August is exponentially more acceptable.

To celebrate the need to crank the heat and bring my potted veggies and herbs indoors, I made soup. Potato soup!

Just looking at that bowl-o-deliciousness makes me want to grab a spoon and dive in!

Serving Suggestions + Topping Ideas

There are SO MANY delicious toppings you can add to potato soup.

Keep things classic with a combination of cheddar, sour cream bacon, and chives or opt for a vegetarian version with plant based bacon bits or skipping the smoky topping altogether.

My Sriracha Roasted Chickpeas and Crispy Roasted Shawarma Chickpeas also taste absolutely stellar on top of potato soup. They’re smoky and spicy and just so delish!

Another fun topping combo that I absolutely adore is to add a scoop of vibrant green pesto and garlic croutons on top.

Questions & Reviews

  1. Thanks so much for the tip on making the pesto stay green. I never thought of blanching the leaves first, but it makes perfect sense! I often make a batch and freeze part of it in the fall when the garden is winding down and always disliked how brown looking it is when I pull it out of the freezer. Sure it tastes OK, but not as eye appealing as fresh. This technique is awesome – can’t wait to try it!

    1. It was a total lightbulb moment for me too! Now my pesto is shockingly green – love it so! <3 Hope you get a chance to try it soon Char 🙂

  2. Now that is one delicious bowl of comfort food and that pesto and garlicky croutons take this dish over the top. Totally know how you feel about the cold…I swear my blood has gone thin living in Hong Kong. Shring, of course!

  3. Potato soup, you had me at potatoes. Love potatoes, and I’m sure I will love this soup. I always keep a jar of pesto in the fridge for making quick and easy meals and adding some to this soup sounds just right to me. Cold fronts are fun, we just had one come through Texas and I’m so happy. I’m ready to start wearing my winter clothing, it’s almost December.
