Simple Walnut Pesto on pastaTry this delicious Simple Walnut Pesto recipe soon. It’s easy to make and entirely gluten-free. Plus, it’s loaded with healthy ingredients and none of the wonky stabilizers found in store-bought pesto. 

You can use this simple walnut pesto to top polenta, gluten-free pasta, quinoa or make your own gnudi. It’s also fabulous over grilled fish or steak, swirled into mashed potatoes, or to add a kick to soups or stews. I usually keep a container of homemade pesto stashed in the fridge to add a spoonful or two to whatever needs a flavor kick. That’s one of the great things about this recipe – you can store or freeze a good sized portion for dinner, and keep some in a smaller container to cook with.

Why Walnut Pesto?

Why do I use walnuts? Well, they are loaded with Omega-3s and other heart-healthy goodness. Between the basil, garlic, extra virgin olive oil and walnuts, this pesto sauce is not only delicious, it’s good for you too.

Can you switch it up? Yes!

The recipe is fabulous with pistachios – just swap out the walnuts to make your pesto super-green. This recipe also works really well with pepitas/pumpkin seeds – just make sure you get the plump green ones, not the ones you just pulled out of your jack-o-lantern. If you’d like to cut out the cheese, decrease the oil to 1/2 cup total, and add one more garlic clove. You’ll likely need a little more salt with no cheese too. I sometimes throw in a couple of sweet peppers or a squeeze of lemon to swap up the flavors. Sometimes a add a handful of fresh parsley. Try the base recipe once or twice, then make it your own!
