"This creamy and delicious cauliflower Alfredo sauce recipe is a great way to use up the nearly-bad produce in your fridge."

Honestly, nothing beats comfort food. Especially thick, creamy, and rich fettuccine Alfredo. While traditional Alfredo has a heavy cream base, this version swaps in a superfood that tastes just as good as it is for the planet.

Stephanie Manzinali, the vegan food blogger behind @that.veganbabe, recently shared her cauliflower Alfredo sauce on Instagram—which, despite being loaded with veggies, tastes nothing like ’em. “This pasta can be made in 20 minutes or less,” she wrote. “It’s so creamy and delicious, and you can’t taste the cauliflower at all.”

The cauliflower Alfredo sauce is also really easy to make. You simply steam the cauliflower until it’s soft, add it to a blender with the rest of your ingredients (including plant milk, onion, garlic, and cashews), then blend until smooth. Aside from it being dairy-free, it’s planet-friendly in another way, too: It’s the perfect way to use up cauliflower that’s about to go bad.

A delicious and healthy meal that also helps cut down on food waste? Yep, we’re sold. Here’s how to make cauliflower Alfredo sauce, step by step.
