Butternut Squash & Sage Soup | Kevin Wagonfoot

Listen, I was skeptical too. Butternut squash and keto seemed like they’d never get along, like bringing your stern uncle to a pool party. But then I made this soup from the Keto Slow Cooker Cookbook for Beginners, and I realized I’d been overthinking it. The magic is in the portions and the sage—that earthy herb just makes everything better.

I threw everything in my slow cooker on a Tuesday morning and forgot about it until dinner. My kitchen smelled incredible, and I actually had a bowl of soup that didn’t taste like I was punishing myself for wanting to eat. That’s a win in my book.

Why This Works for Keto

Here’s the thing: butternut squash gets a bad rap in keto circles, but it’s really about balance and pairing. This recipe keeps the carbs in check by using reasonable portions and letting the fat from cream and butter do the heavy lifting. The slow cooker does the work for you, breaking down the squash into something silky without any fussing, so you’re left with a soup that’s satisfying and actually fits your macros when you’re careful with your serving size.

Tips & Variations

  • Don't skip the sage. I used fresh when I had it, dried when I didn't, and honestly both work—but that herb is what keeps this from tasting like you're on a diet.
  • I serve mine in smaller bowls than I'd normally use, which somehow makes me feel like I'm eating more. Silly, maybe, but psychology is half the battle.
  • Make a double batch and freeze it in portions. Future-you will be grateful on a night when you'd otherwise order takeout.
