Creamy potato soup is the ultimate comfort food! This Cheesy Pesto Potato Soup is a lighter twist on the classic with all the bowl-licking flavor of the original! Instant Pot + Slow Cooker
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.
We don’t wear flip flops in the Fall solely to make Northerners cringe, it’s out of sheer necessity people! 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 basil indoors, I made soup. Potato soup! And since my fresh basil was snuggled up next to the stove, I decided to let it in on the fun.
Just looking at that bowl-o-deliciousness makes me want to grab a spoon and dive in!

Simple Basil Pesto
- 2 cups fresh basil leaves, stems removed
- 1/4 cup walnuts (or pine nuts!)
- 2 large cloves of garlic
- 1/2 cup extra virgin olive oil, plus extra to taste
- 1/2 cup freshly grated parmesan cheese
- (optional) salt and pepper to taste
My go-to trick for pesto that stays vibrant green (even when frozen) is blanching before blending! Toss your basil leaves in boiling water to blanch briefly. Once they turn bright green, remove leaves with a slotted spoon and add to a bowl of ice water to halt the cooking process. Pat the leaves dry with a paper towel then follow the steps below. This is optional but my absolute favorite technique and well worth the effort for gorgeous green pesto!
- Combine basil, walnuts, and garlic in a small food processor.
- While it runs, slowly pour in your olive oil.
- Add your parm cheese and puree for about a minute or so more.
- Swirl into this soup or serve over pasta, pizza, or anything your heart desires!
You can also use an immersion blender to make the pesto, score!
