What's not to love about pesto. We love it with just about everything.  pesto to the oat milk cream sauce creates a rich, flavorful combination, quick to become your favorite, easy pasta recipe!  Plus, pesto packs healthy punch of good for you, unsaturated fats. The olive oil, nuts, and basil in pesto also provide vitamins, minerals, and antioxidants.

Try making a homemade pesto

In the summer months when basil is in season and readily available, try making your own pesto at home! It’s surprisingly easy to make and only requires a few simple, clean ingredients. Plus, homemade pesto has a much more vibrant flavor with oftentimes less sodium than the store-bought versions. 

Pesto is traditionally made with pine nuts, but you can use any nut you like! Walnuts, macadamia nuts and pistachios are all great alternatives that give a similar rich, nutty flavor. Pesto is most commonly made with basil, but if you’d like to switch up the flavor and try something new, other leafy greens like kale, spinach, and arugula are great options. If you prefer a cheese-free pesto, nutritional yeast mimics the Parmesan cheese flavor and thickens up the sauce like a shredded cheese would.

Add your favorite ingredients for a heartier meal

This recipe is a great base to customize as you like. To make it hardier and even more flavorful, add your favorite vegetables like onions, zucchini, broccoli, bell peppers, or mushrooms. For some protein, top with chicken or your favorite plant-based meat alternative. For the best timing, we recommend cooking your vegetables and protein in a separate pan while boiling pasta and making the sauce so all ingredients are done around the same time.
