This paleo fettuccine alfredo is rich, creamy, and surprisingly dairy-free — all the decadence without the dairy.
I’ve become a little obsessed with grain-free pastas lately. They satisfy my pasta cravings in ways I didn’t expect. This version uses a grain-free fettuccine and a luscious cauliflower-based sauce, and it’s one of those recipes that even devoted traditional-pasta lovers will enjoy.
The idea for this sauce actually came to me in a yoga class — sometimes inspiration strikes at the most inconvenient times. I experiment with dairy-free cream sauces often: sometimes cashews, sometimes coconut, and occasionally other ingredients that don’t make the final cut. This cauliflower sauce, however, is totally blog-worthy: creamy, flavorful, and easy to make.
Combine that with a high-quality grain-free fettuccine and you have a dish that’s both comforting and lighter than the conventional Alfredo. I used an almond-based fettuccine for a pleasant texture and extra nutrition. Don’t let the ingredient list scare you — the result is indulgent and extremely satisfying.
Healthful benefits in this paleo fettuccine alfredo:
Cauliflower supports digestion and contains vitamins like B and K, along with omega-3 fatty acids. It has antioxidant and detoxifying properties and contributes fiber and micronutrients that support overall health.
Almond-based pasta and almond milk add nutrition, including protein and healthy fats. Almonds are naturally gluten-free and bring additional vitamins and minerals to the dish.
Nutritional yeast provides a savory, cheesy flavor without dairy, and also contributes B vitamins, amino acids, iron, zinc, selenium, and some fiber, making it a useful ingredient for plant-based recipes.
Garlic brings antiviral and antibacterial benefits, and a distinctive flavor that rounds out the sauce. It’s a traditional remedy in many systems of medicine and a flavorful addition here.
