Can't wait to share this Roasted Cauliflower Alfredo! I'm always up for a creamy pasta dish! I usually opt for blended cashews since the texture is smooth and creamy but I tried the same method that I usually do but with roasted cauliflower and it was a winner. It has a bit more texture to it than a cashew based sauce but the flavor is perfect and it's great when you want a lighter sauce. This Roasted Cauliflower Alfredo makes such a tasty dish that can be eaten on it's own or served with steamed vegetables, garlic bread, or a side salad.
What You Will Need For This Roasted Cauliflower Alfredo
- Roasted Cauliflower
- Pasta Noodles
- Onion & Garlic
- Campanelle Noodles: Any noodle will do! You can use the traditional fettuccine noodle, penne, rigatoni. It really doesn't matter! You can also use a gluten-free noodle.
- Unsweetened Plant Milk: Use water! I think using plant milk as it gets very creamy but water will also work just fine.
- Yellow Miso Paste: Miso Paste is never optional to me. It adds a delicious flavor but if you don't have it or want to buy it, leave it out. You may need to compensate and add more salt.
How To Make The Best Roasted Cauliflower Alfredo
Spread the cauliflower apart so pieces aren't touching. This will help even browning and proper roasting. Same with the onions. If the pan is too small the onions will steam instead of brown so be sure to give them enough space.
Another trick for onions is to leave them alone. Toss them only occasionally will also help brown them and they develop more flavor.
Serve this delicious creamy pasta with a side salad, garlic bread, a toasted baguette, or steamed vegetables. This pasta could also be a meal on it's own and doesn't really need a side but I can't resist a bowl of pasta and toasty piece of bread.
